The Ornn Compute Price Index (OCPI) was launched in late 2025 to provide a standardized benchmark for the rapidly maturing GPU-as-a-Service (GPUaaS) market. Traditionally, hardware prices follow a predictable depreciation curve as newer, more efficient models are released. However, the H100 has defied this pattern. In early 2024, H100 units were sold for $25,000–$30,000, with secondary market prices occasionally exceeding $40,000. By late 2025 and early 2026, instead of falling as the Blackwell (B200) architecture was announced, H100 rental rates surged. For example, 1-year contract prices rose from $1.70 in October 2025 to $2.35 in March 2026. This “price inversion” is historically rare in hardware but has been driven by the unprecedented scale of the generative AI boom and persistent supply chain bottlenecks in High Bandwidth Memory (HBM). The addition of the OCPI to the Bloomberg Terminal in April 2026 marked the transition of compute from a specialized service to a commodity with financial reference rates.
My prediction for the Ornn H100 SXM compute price index is based on a synthesis of direct index reports, market proxy data, and the broader supply-demand dynamics of the AI hardware sector. As of May 12, 2026, the available data presents a market characterized by a “price inversion” where older hardware (H100) is seeing price increases rather than typical depreciation.
Direct anchors for the Ornn index are critical. In March and April 2026, the index reportedly reflected 1-year contract levels of approximately $2.35 per GPU-hour, a 38% increase from $1.70 in October 2025. Other benchmarks, such as the Neo Cloud H100 index, stood at $2.64 in April. However, Ornn’s own platform and associated prediction markets for late May 2026 show lower clusters between $1.78 and $2.17. This suggests that the official spot transaction index—which the question targets—may be slightly more conservative than the 1-year contract rates cited in industry reports.
Supply-side data supports a sustained high-price environment through July 2026. Nvidia’s Q4 FY2026 earnings call confirmed that H100 (Hopper) capacity remains “sold out” across major cloud providers. Furthermore, lead times for the newer Blackwell (B200) architecture remain at 6-7 months as of April 2026, ensuring that H100 hardware will continue to fill the supply gap for at least another quarter. SEC filings from infrastructure providers like IREN and Applied Digital show billions of dollars in committed capital for GPU expansion, indicating that demand has not yet been satiated by new capacity.
However, I must account for the “Blackwell cliff.” The new B200 architecture offers significantly better efficiency (reported as 35x lower cost per token). As Blackwell units begin to ship in higher volumes throughout mid-2026, the premium for older H100 units will likely face downward pressure. The July 31 resolution date is approximately 80 days from the current data point. While 80 days is not enough time for a total market crash, it is enough time for the “fear of missing out” pricing to stabilize.
Weighting these factors, I have anchored the most likely value at $2.28. This sits between the $2.35 contract benchmarks and the $2.17 prediction market clusters, allowing for a slight moderation in the steep upward trend seen in early 2026. The 50% HDI of $1.98 to $2.58 reflects the volatility seen in semiconductor price indices (1.5% monthly standard deviation) and the potential for shifts in how Ornn normalizes its transaction-based data. Higher-end scenarios ($2.75+) are possible if supply chain issues like High Bandwidth Memory (HBM) shortages persist into 2027, while lower-end scenarios ($1.80) would follow if Blackwell deployments accelerate significantly before the end of July.
Question: what will the Ornn H100 SXM USD compute-price index read (nearest $0.05) at/closest to 4:00pm New York on 31 July 2026. Forecasters largely agree the best public anchors are Ornn-linked live prints in mid-April–mid-May 2026 (~$1.80–$1.95), GPU Markets’ $2.14 fix (18 Apr), and SemiAnalysis’s 1‑yr contract reading of $2.35 (Mar 2026), so most weights center the distribution in the high-$1s/low-$2s (median ≈ $1.90–$1.95) with an implied σ ≈ $0.30–$0.35. Consensus reasoning: very strong hyperscaler and AI demand plus HBM/packaging bottlenecks make a large price collapse unlikely before July, while cheap public listings (ComputePrices shows many ~$1.50 offers) and Blackwell ramp create a meaningful downside tail; contract-market tightness supplies the principal upside risk. Quantiles across models put ~90% mass roughly between ~$1.33 and ~$2.63, with small (<~1%) probability mass above ~$3 or below ~$1.40. Forecasters differ mainly on tail weights and how much public scraped offers should pull the Ornn transaction-based index down; the report emphasizes getting Bloomberg/Ornn API prints as the highest‑value pre-resolution update.
Forecast: Probability distribution:
We are forecasting the Ornn H100 SXM USD compute price index at 4:00pm New York time on 31 Jul 2026 (~11 weeks out from 12 May 2026). Across analysts, the main anchor is that the index in early May 2026 is around the high-$1.7s to ~$1.9 per H100-hour (transaction-based/spot-like index), with recent spring 2026 history largely in the ~$1.7–$2.0 band and occasional excursions higher in adjacent markets/contract anecdotes.
Key drivers into late July:
Reconciling analyst disagreement:
Synthesis: I center the distribution slightly above the “~$1.8–$1.9 now” anchor (median ~1.95) to reflect persistent demand and the possibility of mild upward drift, while keeping a meaningful downside tail (Blackwell substitution / easing supply) and a moderate-but-real upside tail (renewed scarcity/volatility). I do not place meaningful probability outside the 1.0–5.0 broad bounds; extreme outcomes seem very unlikely for this specific index on this short horizon.
A typical amateur forecast here would either (a) repeat the very wide 1.0–5.0 range without tying it to the H100 SXM index level, or (b) anchor on a single retail cloud list price (often much higher than transaction-based indices) and extrapolate incorrectly.
This forecast improves by (1) anchoring on the cross-analyst consensus of the index level in early May (~high-$1.7s to ~$1.9), (2) explicitly incorporating the two opposing mechanisms most cited by the analysts (Blackwell substitution vs persistent demand/shortage), and (3) keeping tails wide enough to be calibrated for spot-volatility while not overreacting to out-of-family signals (e.g., Blackwell price spikes) that may not transmit one-for-one to H100.
Overall confidence: moderate. The horizon is short, which helps, but the index can still jump on relatively small liquidity/availability changes, so tail risk remains material.
Forecast rationale (numeric):
— Iteration 1 — The forecasts are grounded in a few common anchors and assumptions:
Main difference: one forecast is slightly more optimistic and places the center closer to $1.90, while the other is a bit more conservative around $1.70. Overall, though, they agree the most likely outcome is somewhere around the high-$1.6 to $1.9 range, with only a small probability of extreme moves.
— Iteration 2 — The forecasts broadly converge on a similar picture:
Overall, the shared view is of a slightly declining but still fairly elevated compute price, centered in the low-to-mid $1s, with moderate volatility and a small chance of sharp upward spikes.
— Iteration 3 — The forecasts converge on a moderately stable to slightly softer H100 SXM compute price index by late July 2026, anchored by the most recent observed print and current site indications.
The collective view is that Ornn’s H100 SXM compute price index on 31 July 2026 at 4:00pm New York time is most likely to remain near current levels, with a slight bias downward, driven by improving supply and competition but cushioned by ongoing AI demand.
Summary of Forecasting Rationales
The forecast for the Ornn H100 SXM compute price index is driven by a tug-of-war between extreme structural supply constraints and the deflationary pressure of next-generation hardware rollouts. Across the rationales, several key themes emerge:
Recent Volatility and Demand Shocks Forecasters universally highlight a recent, aggressive spike in H100 spot prices. After a prolonged period of depreciation, the market experienced a “parabolic” surge driven by the release of new frontier AI models and sudden, massive training and inference requirements. This panic buying severely depleted spot liquidity, establishing a high short-term premium.
Upward Pressures: Structural Bottlenecks and Power Constraints Despite being an older architecture, the H100 is retaining its value as a vital “bridge” solution due to severe macroeconomic bottlenecks. The deployment of the next-generation Blackwell (B200) architecture is heavily delayed by physical supply chain issues, including advanced packaging capacity limits and high-bandwidth memory shortages. Furthermore, data center infrastructure is constrained by electrical grid limitations, transformer backlogs, and impending summer heatwaves that threaten to throttle compute capacity. As long as these physical and power constraints persist, H100 demand remains inelastic, maintaining a firm floor on spot prices.
Downward Pressures: Mean Reversion and Next-Gen Cannibalization Conversely, a major downside risk is the eventual mean reversion of the recent demand shock. Most rationales argue that the current price spike reflects a temporary “desperation premium” that will cool once initial frontier model workloads conclude. More importantly, as the B200 instances finally clear their backlogs and come online over the summer, they offer vastly superior price-to-performance. This migration to newer architectures is expected to flood the secondary market with offloaded H100s, naturally depressing the index.
Index Mechanics and Expected Volatility Forecasters note that the Ornn index utilizes a volume-weighted methodology based on executed, negotiated clearing prices. This mechanism smooths out extreme, idiosyncratic retail price spikes or brief intraday anomalies. However, because compute is a flow commodity in a zero-inventory environment, the market remains fundamentally volatile.
Conclusion Overall, the rationales anticipate that the recent acute price spike will partially subside as the market cools and newer architectures deploy. However, persistent structural shortages, high inference demand, and data center power limits will likely prevent a total price collapse, establishing a new, elevated baseline with wide potential tails for both supply gluts and sudden scarcity shocks.

The research outlines the development and current status of the Ornn Compute Price Index (OCPI), which tracks AI compute pricing, specifically focusing on the Nvidia H100 SXM GPU. The OCPI is designed to provide a sustained benchmark for rental pricing, capturing transaction-level data across various hardware configurations and deployment contexts. As of May 2026, the OCPI-H100 SXM value is reported at $2.74 per GPU-hour, reflecting a significant increase from approximately $1.70 in October 2025. The research highlights various competing indices that show discrepancies in pricing trends, emphasizing the different methodologies used to derive these values.
Additionally, the research discusses key factors influencing the price forecast for July 31, 2026, including potential downward pressures from the upcoming release of the B200 GPU and increased supply, as well as upward pressures from substantial investments in AI infrastructure. The prediction markets, particularly OctagonAI, suggest a possible decline in prices, while the OCPI remains elevated. The analysis indicates a range of potential outcomes for the OCPI-H100 SXM price, depending on market dynamics and supply-demand shifts leading up to the specified date.
Sources used in the research include:
The Ornn Compute Price Index (OCPI) is the first sustained benchmark tracking AI compute pricing, created by Ornn AI Inc., a New York-based company building financial infrastructure for the AI sector. It tracks negotiated transaction-level rental pricing for major GPU models (including Nvidia H100 SXM, A100, H200, B200, and RTX GPUs), normalized across hardware configuration, provider, and deployment context [4][8][15]. The index was added to the Bloomberg Terminal on April 2, 2026, approximately six months after going live (~October 2025) [8][15]. Over 400 data center operators, investors, and AI companies currently use the platform [8].
| Date | Price (USD/GPU-hour) | Source |
|---|---|---|
| Oct 2025 | ~$1.70 | SemiAnalysis one-year contract data [6][11] |
| Early March 2026 | ~$2.31 | Tomasz Tunguz / Ornn data [1] |
| March 2026 | ~$2.35 | SemiAnalysis [6][11] |
| ~Feb-March 2026 | ~$2.75 | Ornn (baseline for Blackwell comparison) [9][11] |
| May 6-11, 2026 | $2.74 | Ornn official website, OCPI-H100 SXM live value [4] |
Key trend: H100 rental prices surged ~40% from October 2025 ($1.70) to March 2026 ($2.35), then appear to have stabilized around $2.74 by May 2026 [4][6][11].
There are four GPU price indices on Bloomberg (Silicon Data, Ornn AI, Compute Desk, SemiAnalysis), and they show significant discrepancies in price levels and trends [17]:
The differences reflect varying methodologies—Ornn captures negotiated/transaction prices while cloud provider list prices can be significantly higher [7][17].
OctagonAI — “Price of NVIDIA H100 SXM compute by May 31, 2026?” references Ornn OCPI as the settlement basis. As of May 12, 2026, prediction market forecasts suggest prices around $1.78-$1.82/GPU-hour by May 31, 2026 [16]. This is notably below the current $2.74 live reading, which could reflect expectations of a near-term price decline, or differences in how the resolution price is determined.
OctagonAI — “NVIDIA H100 SXM Compute Price Up or Down by Apr 17, 2026?” showed probability of exceeding $1.7617 rose from 44% to 57% [2]. This suggests the market’s strike price was around $1.76, implying the index was near that level at some prior point.
Polymarket — “GPU rental prices (H100) hit_ by April 30?” used Silicon Data’s H100 Index (SDH100RT), not Ornn. Total volume ~$569,716. The market on whether prices would hit $2.50 by April 30 resolved “No” [19]. This is a somewhat liquid market but tracks a different index.
Liquidity/reliability note: The Polymarket had ~$570K volume (moderate liquidity). OctagonAI market volumes were not specified but appear to be smaller/newer markets [16][19].

The current OCPI-H100 SXM value is $2.74/GPU-hour as of May 11, 2026 [4]. The key question for July 31 resolution is whether the recent price surge (from ~$1.70 in Oct 2025) represents a sustained new equilibrium or a temporary spike that will partially revert as Blackwell supply increases.
The OctagonAI prediction market (the closest available market using Ornn data) implies a significant decline to ~$1.80 by end of May [16], while the current Ornn live reading remains elevated at $2.74. This discrepancy is a critical uncertainty—it could reflect:
By July 31, 2026 (~2.5 months out), reasonable scenarios span from ~$1.50 (if Blackwell ramp significantly displaces H100 demand) to ~$3.00+ (if supply constraints persist and AI demand continues surging). The rounded-to-$0.05 resolution format means the answer will be a value like $1.50, $2.00, $2.50, $2.75, etc.
Key data gaps: No complete historical daily OCPI time series is publicly available, no deep-liquidity prediction market exists specifically for the Ornn H100 SXM index on July 31, 2026, and the index has only ~8 months of history, making statistical analysis of volatility difficult [16].
The critic makes several compelling points that warrant further adjustment:
B200 at $4-5/hr is NOT direct price competition: This is the strongest argument. The B200 is nearly 2x the price of H100. It’s targeting premium training workloads, not displacing H100 for cost-conscious users. My bearish thesis relied too heavily on generic “Blackwell pressure” without examining the actual price dynamics.
Supply constraints are concrete and persistent: 90% zero availability, TSMC CoWoS booked through 2026, $700B AI capex planned. These aren’t speculative—they’re documented facts supporting price stability.
Short timeframe limits structural changes: 80 days is genuinely insufficient for dramatic market restructuring. The 40% surge took 5 months; expecting comparable moves in half that time without a clear catalyst is questionable.
Potential upward price convergence: OCPI negotiated prices at $2.74 vs. cloud list prices at $3.33-$3.73 means there’s room for prices to rise as the market matures and demand strengthens.
I still believe:
The “H100 as value tier” argument is particularly compelling. As the market segments into premium (B200 for cutting-edge training) and cost-optimized (H100 for inference, budget training, smaller organizations), H100 could maintain strong demand precisely because it’s cheaper than Blackwell—not despite it.
I’m raising my median from $2.45 to $2.50, representing a ~9% decline rather than 11%. This better balances:

Looking at the critic’s new research, I need to substantially revise my forecast based on critical new information.
The critic has uncovered what appears to be a fundamental baseline error in my previous forecasts:
Current price is much lower than assumed: The Ornn website shows H100 SXM prices around $1.80-$1.90, not the $2.74 I was working with. This is a ~30-35% discrepancy.
The OctagonAI prediction market now makes sense: I was skeptical of the $1.78-$1.82 prediction because it implied an implausible 35% crash. But if current prices are actually ~$1.85, the prediction market is simply saying prices will stay roughly flat - a much more reasonable expectation.
Multiple independent sources converge: Ornn website (~$1.85), OctagonAI (~$1.80), and cloud rental surveys ($1.80 at lower end) all point to the $1.80-$2.00 range as current market level.
My entire distribution was mis-anchored: Building around $2.74 when actual current is ~$1.85 means my median of $2.45 would require a ~32% increase, not a decline.
Wide uncertainty is appropriate: With only ~8 months of index history and apparent high volatility (if the $2.74 was ever accurate), the tails should remain fairly wide.
Modest upward bias makes sense: Persistent AI demand and supply constraints could push prices up somewhat from current levels by July.
Blackwell pressure is real but constrained: B200’s TCO advantage exists, but CoWoS packaging remains fully booked through 2026.
Starting from current ~$1.85:
I’m accepting the critic’s reframed distribution with minor adjustments - slightly wider upper tail given demonstrated price volatility.
Updated prediction: Percentile 0.1: 1.05 Percentile 1: 1.20 Percentile 5: 1.40 Percentile 10: 1.55 Percentile 20: 1.70 Percentile 30: 1.80 Percentile 40: 1.90 Percentile 50: 2.00 Percentile 60: 2.15 Percentile 70: 2.30 Percentile 80: 2.55 Percentile 90: 2.90 Percentile 95: 3.30 Percentile 99: 4.05 Percentile 99.9: 4.85
The critic raises several valid concerns that merit careful consideration.
1. Prediction Market Signal: I may have been too dismissive. Even discounting for the market’s apparent newness and unspecified volume, a prediction market expecting ~$1.80 by end of May (vs. current $2.74) represents significant aggregated information. The ~35% gap is too large to completely dismiss.
2. Mean Reversion: The critic correctly notes that I anchored heavily on the current $2.74 reading, which sits near the top of the observed historical range. Commodity indices do exhibit mean-reversion, and the recent 40% surge from October 2025 levels suggests overshoot potential.
3. P0.1 Adjustment: The question creator explicitly states <$1.00 is unlikely. My 0.90 was inappropriately low.
4. Analyst Expectations Alignment: My median representing only ~14% decline from current levels does sit at the optimistic end of the 10-20% analyst range. Given multiple bearish factors converging, centering closer to the middle of that range is warranted.
1. Current Price Anchor Validity: The Ornn live reading of $2.74 is the most direct observable data. The massive gap with prediction markets could reflect methodology differences, timing issues, or even prediction market error—not necessarily superior information.
2. Supply Constraint Reality: 90% supplier availability at zero, TSMC CoWoS fully booked through 2026, and $700B in AI capex are concrete bullish factors that provide genuine price support.
3. Volatility Uncertainty: With only 8 months of index history, predicting 2.5-month movements with high confidence is inappropriate. I maintain the need for relatively wide tails.
The discrepancy between multiple Bloomberg indices (Compute Desk at $3.50, Silicon Data at $2.64, Ornn at $2.74) suggests significant methodology-driven variation. This means the “true” market-clearing price has substantial measurement uncertainty, which should be reflected in wider confidence intervals.
I’ll shift my distribution modestly leftward to:
However, I’ll maintain appropriate probability on the right tail given supply constraint risks and the historical tendency for GPU pricing to spike during demand surges.

Agent Forecast (discrete, confidence: medium-low)
Base Rate: Ornn ORNNH100 has tracked in a $1.70-$1.85 band from March-May 2026, with ~$0.05-0.08/month upward drift. No observation of the Ornn H100 SXM index above $2.00 in its tracked history; broader list-price indices (SemiAnalysis ~$2.35, Compute Desk ~$2.18) sit 20-30% higher due to methodology differences. The closest forward market signal is the Robinhood May-31 monthly H100 SXM contract with ~50% probability above $2.17.

Reviewer Panel:
Reviewer (reasoning)
The forecast’s weakest link is its simple linear extrapolation of a ~$0.05–0.08/month price rise through July, which ignores likely supply ramps, second-hand market effects, and potential H200 adoption that could sharply dampen H100 SXM pricing. It also overweights a single Kalshi contract’s “implied median” without considering that Kalshi’s market structure and bid–ask spreads can distort the true expected value. Finally, it fails to account for recently announced NVIDIA supply increases and enterprise commitments that may cap prices well below $2.50 by late July.
Objections:
Reviewer (calibration)
The forecast’s central estimate for July relies on extrapolating a significant price jump implied by Kalshi’s May market (relative to current Ornn values) but then reverts to a slower growth rate for June/July without fully justifying this shift. While acknowledging Blackwell as a downside risk, its potential impact on H100 supply-demand dynamics and price by July 2026 is not sufficiently integrated into the probability distribution. The analysis could better reconcile the ‘steady upward trajectory’ of Ornn’s past with the market’s expectation of an imminent, accelerated surge.

Adjustment Rationale:
Adjusted by (1) tightening source attribution: the May-31 prediction-market reference is a Robinhood-listed H100 SXM monthly contract showing ~47-56% probability above $2.17 (corpus-implied median range $1.83-$2.17), not a directly-quoted Kalshi May contract; (2) shifting ~5 points of probability from the 2.5-3 and 3-4 buckets into the 1.5-2 and 2-2.5 buckets to better reflect the Blackwell/H200 supply-ramp downside that calibration and reasoning reviewers correctly flagged was under-weighted; and (3) lowering confidence from medium to medium-low, since linear extrapolation of $0.05-0.08/month Ornn growth through 2.7 months ignores plausible non-linear effects (Blackwell displacement, secondary-market depreciation, enterprise pooling). Held firm on the central tendency — the Ornn ORNNH100 series has trended steadily from ~$1.70 in March to ~$1.85 in May 2026 with no observed reversal, so the modal bucket remains $2-$2.5, but the distribution is now wider on both sides.

Model’s Answer: Step one is to anchor on the exact resolution source rather than broader GPU pricing chatter. The most important evidence is the official Ornn dashboard and Ornn homepage, both current to May 11, showing the H100 SXM USD index at 2.74. That matters much more than generic cloud list prices, survey-based benchmarks, or stale exchange pages, because this question resolves specifically to the Ornn H100 SXM index.
Step two is to look at the limited but relevant history. We have a verified end-March value around 1.76, a March 25 reading around 1.72, and evidence that the same market has recently been capable of spiking near 4.95. So this is not a low-volatility series. In roughly six weeks it moved from the high 1s to the high 2s, with evidence of temporary excursions much higher. That argues against a narrow forecast.
Step three is to decide how much of the recent jump to 2.74 should persist into late July. My base case is mild mean reversion, not a full reversal. H100 is still a highly usable product in mid-2026, but it is no longer the frontier part, so continued supply growth and substitution toward H200 and Blackwell-class hardware should create some downward pressure. Against that, legacy demand, inference demand, and periodic spot tightness should keep H100 from collapsing. That leads me to a center a bit below the latest print, with a broad right tail because the series has already shown it can squeeze upward violently.
Step four is source weighting. I put the most weight on Ornn dashboard and Ornn homepage because they are current and directly tied to resolution. I put moderate weight on the Kalshi March resolution because it confirms how the index is used and gives an exact historical anchor. I put moderate but clearly lower weight on SemiAnalysis because it is adjacent, not identical. I put low weight on the Ornn trade page showing 1.80 because it appears lagged or inconsistent with the more authoritative sources. I put low weight on social posts about 4.95 because they are anecdotal, but they are still useful evidence that the upper tail is real.
Step five is to pressure test the forecast with the key assumptions most likely to be wrong.
The first key assumption is that the May 11 reading of 2.74 is representative rather than a stale or transient spike. I assign about a 25% chance this assumption is materially wrong. If wrong, the entire distribution should shift lower by roughly 0.30 to 0.70.
The second key assumption is that H100 SXM remains a reasonably liquid, actively traded reference market through July rather than rapidly de-rating as newer chips take share. I assign about a 30% chance this is materially wrong. If wrong on the downside, July could land closer to the mid 1s or low 2s.
The third key assumption is that there is no major supply shock, power constraint, export-policy disruption, or sudden demand wave in the last two and a half months. I assign about a 15% chance this is wrong. If wrong, the right tail above 5 becomes much more plausible.
A low outcome would most likely come from faster-than-expected migration to newer GPUs, broadening H100 supply, or the current 2.74 print unwinding as a short-lived squeeze. I think 1.50 or lower is roughly a 7% to 8% event, while a print below 0.975 is very unlikely, around a few tenths of a percent.
A high outcome would most likely come from another spot shortage, a burst of inference or training demand, or a market structure issue where small traded volume pushes the index sharply higher. I think 4.50 or higher is roughly an 8% event, and above 5.025 is a low-probability but real tail, around a few percent.
Overall, the best single-point view is a median near 2.60, with a fairly wide 90% interval centered roughly from the mid 1s to the mid 4s. Because this is a short-horizon market-price question with sparse exact historical data but known jumpiness, I am intentionally keeping the tails fatter than a simple trend extrapolation would suggest.

Forecast: median = 2.6882
Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary The estimate for the Ornn H100 SXM compute price index on July 31, 2026, centers on a median of $2.35, reflecting a slight moderation from early May 2026 spot prices of approximately $2.65 to $2.78. This spot market is characterized by extreme volatility, having swung from roughly $1.72 per hour in late March to a peak of $4.95 in late April before correcting. The baseline expectation is that prices will drift downward over the summer. While demand for computing power to support agentic AI applications remains intensely strong, the ongoing volume production and deployment of next-generation architectures like Blackwell are expected to begin alleviating supply bottlenecks. Because there is typically a lag before new chip deployments materially ease spot market constraints, prices are anticipated to soften gradually rather than collapse. However, the extraordinarily wide distribution—spanning from $1.50 at the 10th percentile to $4.15 at the 90th percentile—accounts for the market’s demonstrated capacity for sudden, drastic price swings.
Strongest Arguments for Higher Values • Sustained GPU Shortages: Broader industry supply constraints are widely expected to persist through August or September 2026, meaning overall compute demand could continue to outstrip available capacity. • Explosive Demand Spikes: The market has proven highly reactive to sudden bursts of demand for AI training and inference, as evidenced by the dramatic price surge in late April 2026. • Hardware Rollout Delays: If the mass deployment of newer systems encounters unexpected production bottlenecks or data center integration delays, reliance on existing H100 clusters will remain high.
Strongest Arguments for Lower Values • Generational Depreciation: The H100 is an aging architecture, and as more efficient next-generation systems come online in larger volumes, the premium on H100 instances will naturally erode. • Continuing Downward Corrections: The sharp drop from the April high of nearly $5.00 down to the $2.70 range suggests that peak prices were anomalous, and the broader trajectory may trend downward as global compute capacity steadily improves. • Rapid Clearing of Bottlenecks: If new chip production and cloud deployments accelerate faster than anticipated, spot market constraints could resolve sooner, driving prices swiftly toward the $1.50 range.
Key Uncertainties • Volume and Timing of Deployments: The exact pace at which next-generation hardware becomes widely available for spot rental will dictate the speed of H100 price depreciation. • Unpredictable Demand Shocks: The potential for large technology firms or AI startups to suddenly secure massive spot allocations for new model training runs introduces significant tail risk for price spikes. • Intrinsic Spot Market Volatility: The underlying index has demonstrated swings of over 100% within a matter of weeks, making it difficult to rule out extreme outcomes in either direction.
This market settles on Ornn’s own H100 SXM USD index, not on raw advertised cloud prices. That matters because Ornn says OCPI is normalized across hardware configuration, provider, and deployment context, is distributed on Bloomberg, and reflects negotiated transaction levels / real trades. An older October 2025 Ornn methodology document, however, described a live-offer/availability-weighted construction for the H100 index, so I include a modest extra uncertainty premium for possible methodology evolution between the older paper and the current 2026 product description. (prnewswire.com)
My level anchor is the high-$1.8s to low-$1.9s. Ornn’s public homepage, as recently crawled, displayed OCPI-H100 SXM values in the $1.80-$1.90 range. Separately, an Octagon summary of April 30 H100 settlement markets reported that Kalshi contracts up through the $1.95 strike resolved YES, implying the April 30 Ornn settlement was above $1.95. I therefore treat the current spot neighborhood as roughly around $1.9, with some source disagreement about the exact print. (ornn.ai)
The broader H100 market has rebounded rather than collapsed. Silicon Data reported a 10% jump in its H100 rental index from $2.00 to $2.20 between December 9, 2025 and January 6, 2026, and its longer history page says non-hyperscale H100 rental rates had already compressed from early-2024 scarcity levels to roughly the $1.5-$3.0 range by late 2025. TrendForce also summarized market chatter that one-year H100 leasing prices had risen materially from late-2025 lows into March 2026. These are not the Ornn index itself, but they do support a regime of sticky demand and non-trivial upside volatility. (silicondata.com)
Demand-side fundamentals still look strong for a July 31, 2026 resolution. Ornn said in April that its dataset had already captured six months of pricing behavior and that more than 400 data center operators, investors, and AI companies were using the platform. TSMC’s 1Q26 management report showed revenue up 35.1% year over year, with High Performance Computing at 61% of revenue, while Reuters reported CoreWeave expects 2026 capex of $30-35 billion to meet massive AI-compute demand. Those are not signs of a near-term demand air pocket. (prnewswire.com)
The main bearish force for H100 by late July is substitution from newer NVIDIA platforms. NVIDIA said Blackwell was already in full-scale production across system makers and cloud service providers, and that Rubin-based products are due in the second half of 2026. NVIDIA also continues to market Blackwell/Rubin on much better inference economics. That should cap H100 upside and creates a plausible easing path by July, but the horizon here is only about 80 days, so I do not expect a full price collapse before July 31 unless supply loosens much faster than the current evidence suggests. (investor.nvidia.com)
I therefore use a four-regime mixture model for the rounded July settlement: 30% easing regime centered at $1.65, 40% stable regime centered at $1.90, 22% tight-market regime centered at $2.15, and 8% squeeze regime centered at $2.65. The weighted mean of those regime centers is $1.94/GPU-hour. My modal rounded outcomes are $1.85-$2.00, with most probability mass from about $1.55 to $2.35. I assign only a tiny probability to a sub-$1.00 print, because Ornn’s own public indication is still in the high-$1.8s and public specialist-provider quotes remain low-single-digit dollars per GPU-hour. I assign only a trace probability above $5.00 for the same reason. Best single rounded guess: $1.90. (ornn.ai)
As of May 12, 2026, Ornn’s public homepage cycles OCPI-H100 SXM values of $1.80, $1.85, and $1.90 in its live section, while a March 4 Data Center Dynamics article citing Ornn described H100 at $1.70. Public H100 SXM offer boards show why I do not anchor directly to any one posted cloud price: ComputePrices lists 32 provider observations from $0.80/hr upward, and Oracle’s March 12, 2026 public price list shows OCI H100 at $10 pay-as-you-go and $6 with annual commitment, so public offer dispersion is very large relative to a benchmark index. (ornn.com)
That dispersion matters because Ornn’s own public materials describe OCPI as a benchmark grounded in real trades or negotiated transaction levels rather than scraped offer boards. So listed prices are useful context, but not a direct settlement proxy. (ornn.com)
The bullish side of the forecast is straightforward: Oracle said on March 10, 2026 that AI training and inference demand continued to grow faster than supply, and CoreWeave said on May 7, 2026 that average pricing for A100s, H100s, H200s, and L40s all increased quarter over quarter while near-term capacity across its fleet remained largely sold out. That is strong evidence that the spring 2026 compute market was still tight, not loosening. (investor.oracle.com)
The bearish side is also real: Blackwell rollout is now underway. Microsoft documents ND GB200-v6 instances, Google has previewed A4 VMs based on NVIDIA B200, and NVIDIA says Blackwell Ultra can deliver far lower inference cost than Hopper, including up to 35x lower cost in one cited comparison and up to 10x lower AI costs for some inference providers. Over time, that should cap H100 SXM pricing by shifting premium workloads to newer hardware. (learn.microsoft.com)
A weak but still useful cross-check is the public May 31 H100 SXM prediction market on Robinhood/ForecastEx. On May 12 it showed 50¢ on Above $1.83, while some strikes above $2.00 were also trading well above 50¢. The display is low-volume and somewhat noisy, so I treat it only as a soft signal, but it is at least consistent with a late-May market in the low-$2s rather than the mid-$1s. (robinhood.com)
My synthesis is modestly bullish but not explosive. July 31, 2026 is close enough that I do not expect Blackwell supply to fully commoditize H100 SXM by then, but far enough away that I also do not want to extrapolate the spring squeeze indefinitely. I therefore center the distribution at about $2.00 per GPU-hour, with the highest mass around $1.95 to $2.05 and most probability between roughly $1.70 and $2.40. To encode that view, the code uses a four-scenario mixture: 20% bearish rapid-substitution case with mean 1.60, 50% base case with mean 1.95, 25% tight-market bullish case with mean 2.25, and 5% upper-tail squeeze case with mean 2.90. The weighted mean of those scenario centers is 2.0025. This leaves meaningful downside if Blackwell substitution bites faster than expected, but still places more mass on stable-to-higher outcomes because the best current primary evidence still describes AI compute demand as outrunning available supply. (investor.oracle.com)
I treated this as a forecast of the official Ornn H100 SXM USD compute index at 4:00pm New York time on July 31, 2026, not as a forecast of generic retail cloud list prices. That matters because Ornn says its compute index is built from real traded spot prices, normalized across hardware configuration, provider, and deployment context, and Ornn announced in April 2026 that the index is available on Bloomberg. So the target is best thought of as a transaction benchmark, not a scraped-offer average. (ornn.trade)
My main anchor is the recent change in the market’s level. DatacenterDynamics reported on March 4, 2026 that Ornn’s H100 index was “currently at $1.70.” A secondary market summary for the April 30 contract family says all 20 April H100 markets resolved YES, with recent winning strikes including $1.91 through $1.95, which implies the April 30 print was above $1.95. Then, as of May 12, 2026, SimpleFunctions’ live aggregation of Kalshi H100 May 31 contracts showed probabilities around 82% for above $1.96, 80% for above $1.99, 79% for above $2.04, 77% for above $2.10, and 75% for above $2.15-$2.17. I read that as the best available market-implied evidence that late-May expectations have moved into the low-to-mid $2s, materially above the $1.70 level seen in early March. (datacenterdynamics.com)
That level is broadly plausible when cross-checked against public offer data. ComputePrices’ early-May snapshot showed examples from about $1.79 per hour for H100 SXM on one provider to $4.31 per hour on Azure, and another early-May market note put exchange spot H100 pricing in roughly the $1.85 to $4.10 range. Because Ornn weights transacted supply rather than hyperscaler sticker prices, I expect the index to sit below the expensive hyperscaler end but above the cheapest distressed or spot-like prints. (computeprices.com)
The directional trend into spring 2026 also argues against a bearish July collapse. SemiAnalysis said its H100 1-year rental contract index rose from $1.70 per GPU-hour in October 2025 to $2.35 by March 2026. That is not the same series as Ornn spot H100 SXM, so I do not map it one-for-one, but it is useful base-rate evidence that H100 economics rebounded rather than continued to slide. Against that, I do expect some summer softening pressure from substitution toward newer accelerators; that part is my inference, supported indirectly by the fact that Ornn is already tracking newer compute types like H200 and B200 alongside H100. (newsletter.semianalysis.com)
I therefore used a three-scenario mixture rather than a single normal forecast: 30% softening case centered at $1.90 with 0.30 sd, 50% base case centered at $2.45 with 0.35 sd, and 20% tight-market case centered at $3.15 with 0.55 sd. The weighted mean of that mixture is $2.425 per GPU-hour, and it places the median/mode in the $2.40-$2.45 area. I keep a meaningful right tail because these compute markets are still young and thin, and the live Kalshi probabilities show sharp repricing over short intervals; but I still assign low probability to extreme outcomes above $5 by July 31. (simplefunctions.dev)
So my best point estimate is $2.45 per H100 SXM GPU-hour for Friday, July 31, 2026 at 4:00pm New York time. The distribution I encoded is centered in the low-to-mid $2s, with most mass spanning roughly $1.90 to $2.95, a smaller downside tail into the mid-$1s if summer softening wins out, and a thinner but still real upside tail above $3 if tightness persists. The code converts that continuous mixture into the required 83 discrete buckets by applying nearest-$0.05 rounding intervals, matching the question’s settlement convention. (simplefunctions.dev)
My anchor is that Ornn’s OCPI is supposed to measure negotiated transaction levels / real trades, not scraped list prices. Ornn’s own methodology paper describes the H100 index as a real-time market benchmark built from executable market data, and Ornn’s April 2, 2026 Bloomberg announcement says OCPI reflects negotiated transaction levels and had only reached six months of live history at that point. A March 4, 2026 DatacenterDynamics report said Ornn’s H100 spot index was $1.70, while a May 2026 crawl of Ornn’s own site showed H100 SXM figures around $1.80-$1.90. That is meaningfully below public posted-rate trackers: on May 12, 2026, ComputePrices showed H100 SXM offers from $0.80/hr to $16.84/hr, with a dense cluster around roughly $1.79-$2.29, and ComputePulse’s public-API H100 index was $2.56. So my starting point is that the July 31, 2026 settlement should likely sit below broad public posted-rate averages and closer to the cheaper transacted end of the market. (ornn.trade)
The directional forces through July 31, 2026 cut both ways. Bullish for H100 pricing: Nvidia said in November 2025 that “cloud GPUs are sold out” and demand keeps accelerating, and Ornn argues compute pricing has been moving through a period of heavy capital deployment. Bearish for H100 pricing: AWS says Project Rainier is already online, Anthropic is expected to use more than 1 million Trainium2 chips by year-end, Amazon says Trainium2 is fully subscribed and nearly all Trainium3 supply is expected to be committed by mid-2026, Meta announced a multi-year AMD Instinct infrastructure agreement with first shipments beginning in the second half of 2026, and Nvidia says Blackwell is in full-scale production while Rubin-based partner products arrive in the second half of 2026. In addition, AWS already showed in 2025 that cloud H100 pricing can be repriced sharply, cutting P5 on-demand pricing by 44% effective June 1, 2025. My inference is that substitute supply is genuinely increasing, but over an 80-day horizon it is more likely to cap H100 than to cause a full collapse before the end of July. (investor.nvidia.com)
Putting those together, my base case is mild easing to roughly flat pricing versus the recent high-$1.7s / high-$1.8s Ornn area, not a dramatic move either way. I put most of the probability mass between about $1.50 and $2.30, with the single highest rounded bucket at $1.85 per GPU-hour. I keep a meaningful right tail into the mid-$2s because ongoing scarcity could keep transacted supply tight even as alternatives ramp. I also keep a smaller left tail below $1.50 because public H100 SXM offers are already as low as $0.80-$1.79 on some venues, so a faster-than-expected migration to Blackwell / Trainium or aggressive neo-cloud competition could pull transaction benchmarks down faster than consensus expects. Because OCPI is still a young benchmark with limited live history, I am using wider tails than I would for a mature commodity index. (computeprices.com)
Bottom line: my median-ish call for the official Ornn H100 SXM USD compute price index at 4:00pm New York time on Friday, July 31, 2026 is $1.85/GPU-hour, with an implied mean in the high-$1.8s. I assign only a very small probability to outcomes above $5 because current public H100 SXM pricing is far below that except for a few expensive outliers, while Ornn is explicitly intended to reflect normalized transaction levels rather than the most expensive posted rates. (computeprices.com)
As of Tuesday, May 12, 2026, the underlying here is best thought of as Ornn’s H100 SXM spot benchmark, not a hyperscaler list price or a long-duration reservation contract. Ornn’s official site says the OCPI tracks live traded spot prices for GPU compute, and Ornn announced on April 2, 2026 that the index is available on Bloomberg Terminal. That matters because the resolution source explicitly prefers the Ornn/Bloomberg H100 SXM USD index. (ornnai.com)
For historical base rates, H100 prices had already compressed materially through 2025: J.P. Morgan’s January 1, 2026 outlook showed H100 neocloud hourly rates at $2.0 in December 2025 versus $2.7 in November 2024. But the direction then tightened again in early 2026. DatacenterDynamics reported Ornn’s H100 spot around $1.70 on March 4, 2026, while SemiAnalysis reported its H100 1-year contract index rose from $1.70 in October 2025 to $2.35 in March 2026 and described on-demand GPU rental capacity as sold out across GPU types. I treat that as evidence that the spring 2026 market was re-tightening, while also remembering that Ornn spot should normally sit below the 1-year contract market. (am.jpmorgan.com)
I do not anchor directly on public cloud sticker prices because they are far wider than the Ornn spot concept. On May 12, 2026, ComputePrices showed listed H100 SXM offers as low as $0.80 to $1.66 per hour across smaller providers, while Thunder Compute’s May 2026 comparison put normalized H100 prices around $6.16 on CoreWeave, $6.88 on AWS, $6.98 on Azure, and $11.01 on Google Cloud. Silicon Data’s April 27 note also showed hyperscaler H100 on-demand rates basically flat around $7.40 to $7.52 from March 1 to April 20, while neocloud pricing moved more. My inference is that the Ornn index should remain much closer to the low/mid transactable market than to hyperscaler list rates, and that it can keep moving even if hyperscaler pricing looks static. (computeprices.com)
For Friday, July 31, 2026, I see two opposing forces. Upward pressure comes from still-tight AI compute demand: SemiAnalysis describes a run on GPUs and sold-out on-demand capacity, and NVIDIA’s latest official results said Blackwell demand was exceptional. Downward pressure comes from gradual substitution and supply growth: Samsung says HBM4 is now shipping commercially and expects HBM sales to more than triple in 2026, which should slowly improve availability of newer accelerators and cap H100 upside later in the year. Early-May prediction markets tied to the same Ornn H100 index were noisy and low-liquidity, but they still leaned upward overall; Robinhood showed May 31 strikes above $2.00 at 75¢ and above $2.17 at 56¢, while Coinbase snippets showed the same $2.17 strike near 89% to 90%. I use those markets only as directional evidence because the venue-to-venue quotes were inconsistent. (newsletter.semianalysis.com)
My forecast therefore uses a three-regime mixture: a 55% base case of continued firmness but partial stabilization, a 25% tight-market upside regime, and a 20% relief/downshift regime. Using regime means of $2.15, $2.60, and $1.75 per GPU-hour gives an expected value of $2.1825 before discretization, so my rounded central forecast is about $2.20. I put most of the probability mass between about $1.75 and $2.70, with thin tails below $1.25 and above $3.50. That leaves room for a genuine squeeze, but it keeps the center of mass below hyperscaler list pricing and below the 1-year contract market, which is where I think the spot-like Ornn H100 SXM index most plausibly settles at 4:00pm New York time on July 31, 2026.
