Historically, OpenRouter has served as a primary gateway for developers to access frontier models from OpenAI, Anthropic, and Google. In late 2025, these three providers were the undisputed leaders in both revenue and request volume. However, the landscape shifted dramatically in early 2025 with the launch of DeepSeek’s R1 model, which signaled the start of a massive increase in Chinese LLM market share (rising from 3% to 13% globally in just two months). By mid-2026, OpenRouter volume had exploded to 25 trillion tokens per week, but this growth was increasingly captured by “open-weight” models and regional providers. A significant precedent for the current volatility was the mid-June 2026 U.S. government intervention, which temporarily banned Anthropic’s Fable 5 and Mythos 5 models for national security reasons, causing a sudden vacuum in the top rankings that Chinese models quickly filled. The week of July 6, 2026, represents the first full week where U.S. labs are attempting to reclaim this lost ground through a new generation of “agent-optimized” and “budget-tier” models like Claude Sonnet 5 and GPT-5.6 Luna.
My analysis indicates that the combined market share for Google, OpenAI, and Anthropic is currently in a state of high volatility due to a fundamental shift in how developers use OpenRouter. Historically, these three providers dominated the platform, but recent data from June 2026 suggests their total token/request share has collapsed from above 70% to approximately 30-33%. This decline is primarily driven by the surge of Chinese models like DeepSeek (which held the #1 spot for four consecutive weeks in June) and Meituan’s LongCat-2.0 (formerly Owl Alpha). These models offer comparable performance for specialized tasks at a fraction of the cost—often as low as $0.30 per million tokens.
As of July 1, 2026, the revenue-based share for the three providers was approximately 47.36% (Anthropic at 26.94%, OpenAI at 15.56%, and Google at roughly 4.86%). However, the resolution criteria for this question rely on OpenRouter’s public rankings page, which measures “weekly demand” based on the number of text requests. Because OpenAI and Anthropic models are priced significantly higher (e.g., $2.00-$5.00 per million input tokens) than their open-weight competitors, their revenue share naturally overstates their request share.
There are strong indications of a potential short-term rebound for the week of July 6th. Anthropic released Claude Sonnet 5 on June 30 and restored access to Fable 5 and Mythos 5 on July 1 following the lifting of U.S. export controls. Similarly, OpenAI announced the GPT-5.6 family (Sol, Terra, Luna) in late June. The introduction of “Luna”—a high-volume, low-cost model priced at $1 per million tokens—is a direct strategic attempt by OpenAI to reclaim request share from Chinese providers.
In my reasoning process, I weighted the recent structural decline (headwind) more heavily than the new product launches (tailwind). While the new models will undoubtedly see a surge in testing during the week of July 6th, the massive volume currently captured by DeepSeek and others makes a return to previous dominance (e.g., >50% share) unlikely in a single week. The most probable outcome is that the “Big Three” will hold a combined share near 33.5%, reflecting a slight recovery from June lows but still constrained by the high-volume, low-cost competition that now defines the OpenRouter ecosystem. The risk of Google falling out of the top 9 is low but present, which would further drag down the total.
The question asks for the combined OpenRouter weekly text request-share (week starting July 6, 2026) of Google + Anthropic + OpenAI, counting each provider only if it appears in OpenRouter’s top-9 author list. Forecasters converge on a mid‑30s central estimate anchored by late‑June token‑share proxies (roughly 32% combined) but emphasize that token share is only a noisy proxy for request share — frontier models can have higher request/share ratios while token‑heavy cheap/open models can depress token‑weighted rankings. All teams highlight Anthropic’s clear near‑term upside (Claude Fable 5 restoration and Sonnet 5 launch/promotions) while OpenAI’s GPT‑5.6 looks to be a restricted preview unlikely to move OpenRouter share immediately and Google showed late‑June weakness. There is modest but non‑negligible risk that OpenAI or Google could be omitted from the top‑9 (which would score them 0), and routing/Fusion accounting on OpenRouter could mechanically alter author‑level counts in ways not visible from token proxies. Forecasters therefore center forecasts in the mid‑to‑high‑30s, with a meaningful lower tail for truncation/dilution and a smaller upper tail if Anthropic adoption or request‑share skew versus token‑share materializes. The summary recommendation is to verify the official OpenRouter weekly request‑share rows (June 29 and then July 6) before finalizing the score.
Forecast: Probability distribution:
We are forecasting the combined OpenRouter text market share (weekly, week labelled “July 6th”) for Google + OpenAI + Anthropic, with the important rule that any of the three not appearing in the top-9 providers for that week contributes 0.
Across the four analyst forecasts there are two clusters:
A key subtlety raised by Forecaster 3 is credible: the question resolves on text request share (or “text market share” as displayed), which can differ from token-volume-based summaries. Cheap/open models can be disproportionately token-heavy, so the big-three share in requests could run somewhat higher than their share in tokens. That supports shifting the central estimate slightly upward versus the lowest token-share anchors (~32%).
Given (a) the short horizon (week commencing July 6, only a few days ahead of the forecast date), which limits plausible week-to-week drift, (b) the more plausible/consistent evidence from Forecasters 1–3 clustering around mid-30s, and (c) a modest upward adjustment for request-vs-token effects plus a small tail probability that the true request-share is closer to the low/mid-40s, I place the median at 36% with moderately wide tails (including some chance of a sharp drop if one provider falls out of the top-9, and some chance of a temporary surge).
An amateur forecast is likely to (1) anchor on general consumer mindshare (e.g., “OpenAI dominates, so combined must be 60%+”) rather than OpenRouter-specific routing economics, or (2) treat a single scraped token-share snapshot as identical to the contract’s text market share by week.
This forecast improves by triangulating the more internally consistent analyst cluster (1–3), explicitly discounting the outlier estimate that appears to rely on non-comparable or dubious inputs, and incorporating a calibrated adjustment for request-vs-token differences while keeping realistic week-to-week volatility. Confidence in being better-calibrated than an amateur is high; confidence in the exact median within ±3–5 points is moderate.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the dominant reasoning pattern is that the combined share of Google, OpenAI, and Anthropic is now viewed as much lower than the roughly 60% seen in mid-2025, mainly because Chinese-origin models have expanded sharply and are now estimated to control more than 45% of traffic. That shift is treated as the core structural driver behind the decline in the Big Three’s combined OpenRouter share.
The forecasts broadly converge on a central estimate in the low-to-mid 30% range. This comes from decompositions that put Google roughly in the 10–18% band, Anthropic around 10–12%, and OpenAI around 4–8%. OpenAI is consistently described as the weakest of the three on OpenRouter, while Google and Anthropic are seen as the larger contributors, though the exact split varies.
A secondary theme is that recent product launches may have stabilized or modestly supported the group’s share. Google’s Gemma 4 and OpenAI’s GPT-OSS are cited as possible offsets to the broader downward trend, but not enough to restore the earlier ~60% level. One forecast also notes that open-model momentum could help the upper end of the range if those releases gain traction.
The main sources of uncertainty are similar across the rationales:
There is broad agreement on direction and scale of change, with only modest disagreement about the exact total and the relative shares of Google versus Anthropic.
— Iteration 2 — Across the forecasts, the dominant theme is a sharp erosion in the combined OpenRouter text share of Google, OpenAI, and Anthropic versus the roughly 60% Western big-three position seen in mid-2025. The main anchor is the April 2026 evidence that Chinese-origin models now exceed 45% of token volume, with no single provider above about 23%, implying a much more fragmented market.
Key reasoning patterns:
Areas of consensus:
Main disagreement:
Overall, the collective reasoning points to the big-three still being important, but no longer dominant—most likely holding around one-third of OpenRouter text market share in the week beginning 6 July.
— Iteration 3 — The forecasts share a common anchor: the latest OpenRouter spend snapshot shows Google, OpenAI, and Anthropic together at about 85.1%, and because the target week is only a couple of weeks later, the base expectation is that their combined share will remain near that level.
Key reasoning patterns:
Overall, the consensus is that the combined share should stay high, likely in the low-to-mid 80s, with meaningful but mostly downside-skewed uncertainty driven by Anthropic pricing effects and competitive share gains elsewhere.
Summary of Rationale Arguments
Platform Metrics and Market Shifts A central theme across the rationales is the distinction between OpenRouter’s measurement of “request share” versus “token volume.” Historically, Google, OpenAI, and Anthropic have maintained a dominant position in API request share, driven by complex enterprise applications and consumer chat tools. However, their raw token volume share has recently seen steep erosion. This shift is primarily driven by the surge of highly capable, ultra-cheap, or free open-weight models (such as those from DeepSeek, Xiaomi, and Zhipu AI), which are increasingly favored for automated, high-token agentic loops. Furthermore, OpenRouter’s internal routing features—which heavily subsidize or default to cheaper alternative models—have structurally entrenched these open-weight competitors.
Upward Catalysts: The “Perfect Storm” of Model Releases Despite the structural shift toward open-weight models, forecasters heavily weight a cluster of major proprietary model releases occurring just before the target week. These catalysts are expected to trigger significant surges in benchmarking and prompt migration:
Downward Pressures and Resolution Risks Counteracting these upward spikes are several structural and seasonal risks. Forecasters note a “summer slump” and the lingering effects of the U.S. holiday weekend, which typically depress the high-volume enterprise API usage that the major U.S. providers rely on. Conversely, international open-weight developers are less affected by U.S. seasonality.
Finally, a crucial resolution risk dictates that if a provider falls out of OpenRouter’s top nine leaderboard, their contribution to this metric drops to zero. While Anthropic’s position is viewed as highly secure, some forecasters highlight minor downside risks for Google (due to recent API infrastructure friction) and OpenAI (due to restricted rollouts and regulatory caps), which could theoretically push them into the platform’s uncounted “Others” category.

The research summarizes late June 2026 OpenRouter rankings and trends showing Chinese models gaining substantial share while U.S. providers declined. Reported rankings for late June list DeepSeek 15.3%, Xiaomi 11.8%, MiniMax 9.6%, Google 8.8% (4th), and OpenAI 7.9% (6th); Anthropic’s position is unclear and reportedly dropped out of the top 5 in early June. The combined market share for Google, OpenAI, and Anthropic is reported to have fallen from about 72% one year earlier (July 2025) to roughly 26–31% in late June 2026. The research emphasizes a spend vs. usage distinction: by dollar spend Anthropic was said to lead (67.2%), OpenAI 12.8%, Google 5.1%, but usage/token-volume metrics (which the Metaculus/OpenRouter “by task” ranking reflects) are dominated by Chinese models.
The report highlights key drivers and uncertainties: sharp Chinese price cuts and lower per-token costs, a near-fivefold token-usage increase on OpenRouter, Anthropic’s mid-June access restrictions and partial lifting in early July, and a resolution rule that any company not in OpenRouter’s top 9 counts as 0% (which makes Anthropic’s contribution highly uncertain). It presents three scenario ranges for the week commencing 6 July: Scenario 1 (Anthropic not in top 9) combined ~15–17%; Scenario 2 (Anthropic returns) combined ~20–29%; Scenario 3 (continued decline) combined ~20–25%; the research’s favored consolidated range is roughly 20–30% combined for the three companies, with Anthropic’s top-9 status as the primary variable.

The OpenRouter text model market has undergone a dramatic shift over the past year, with Chinese AI models gaining substantial market share at the expense of U.S. providers. Here’s what the data shows:
Recent Market Share Data:
According to recent reports from late June 2026, the OpenRouter rankings show:
Critical Finding: The combined market share of Google, OpenAI, and Anthropic has declined from approximately 72% to 30% over the past year [2]. This represents a massive 42 percentage point drop.

Given the 4-day proximity to the target week and strong recent trends, forecasters should heavily weight the late June data points (Google ~8.8%, OpenAI ~7.9%) while considering:
The most likely range appears to be 20-30% combined, with Anthropic’s inclusion/exclusion from the top 9 being the primary variable determining whether the result falls in the lower (15-20%) or higher (25-35%) end of the range.
(a) Time left. Today is July 2, 2026. The target week starts July 6, 2026 and should be finalized once the July 13 week appears on OpenRouter, so I expect the outcome to be known in roughly 11–14 days.
(b) Outside view. The relevant reference class is weekly OpenRouter text-model author/provider share. The base rate has moved sharply: reports using OpenRouter token-share data say Google + OpenAI + Anthropic were around 70% in June 2025 and roughly 30% by June 2026, as Chinese/open-weight models gained share. A late-June provider-share snapshot gave Anthropic 15.3%, Google 8.8%, OpenAI 8.1%, or 32.2% combined. (officechai.com)
(c) Inside view. The latest live model-level data I found, updated July 2, shows the top usage ranks dominated by DeepSeek, Xiaomi, Tencent, MiniMax, OpenRouter, and Z.ai, with Anthropic’s top models still high but GPT-5.5 only at rank 12 and Gemini’s top model at rank 14. Summing the July 2 top-100 model rows by provider gives an approximate current Google + OpenAI + Anthropic token-share near 29.6%. This is below the late-June 32.2% base, but Anthropic’s Fable/Mythos restriction has just been lifted and Fable 5 access is being restored globally, which pushes upward for the target week. (whatstrending.ai)
(d) Outcome if nothing changed. About 29.5–30.0%.
(e) Outcome if the current trend continued. The short-run direction has been slightly downward for the trio, mainly because non-U.S. cheap models are taking more volume. If that continued without an Anthropic rebound, I’d expect roughly 27–29%.
(f) Experts and markets. I am not aware of a dedicated prediction market for this exact OpenRouter provider-share question. The broader expert/commentary consensus is that OpenRouter usage has become fragmented and price/performance-driven, with no single provider owning the market and cheap Chinese/open-weight models taking a majority or near-majority of volume. (dataandluck.com)
(g) Unexpected low scenario. A new free or ultra-cheap Chinese/open-weight model surges during July 6–12, while Anthropic’s restored Fable/Sonnet usage fails to appear on OpenRouter and OpenAI slips out of the top 9, causing OpenAI to be scored as 0. That could put the result in the low-20s.
(h) Unexpected high scenario. Anthropic’s Fable 5 / Sonnet 5 rebound is much stronger than expected, while Google and OpenAI hold steady and one or more cheap-model leaders has capacity, quality, or routing issues. That could push the combined share into the high-30s or low-40s.
Rationale. I anchor on the outside-view late-June value of 32.2% and the broader June 2026 “around 30%” base rate. The latest reconstructed July 2 value is lower, about 29.6%, so I move the center downward from 32.2. I then add back a modest Anthropic recovery effect because restrictions on its most advanced models were lifted just before the target week. My median is therefore close to current levels rather than extrapolating the recent decline too aggressively: 30.0%. The main downside tail is not Anthropic or Google disappearing from the top 9—both look too large for that—but OpenAI is more vulnerable to top-9 exclusion if two fast-rising providers overtake it. The upside tail is mainly an Anthropic rebound plus temporary stalling among the cheap-model leaders.

Conditioning on the question not being annulled.
I accept the critic’s main point: I was still applying too much of a one-sided “token share overstates target-lab request share” discount. The resolution metric is text request share by model author, while most hard public data are token-volume proxies; OpenRouter explicitly distinguishes Market Share as request share, and its dataset docs warn that token counts come from upstream tokenizers and are not directly comparable across providers. (openrouter.ai)
The freshest quantitative proxy still points near 30%. The July 2 whatstrending.ai leaderboard is token volume over the trailing 7 days; summing visible top-100 rows gives roughly Anthropic 6.15T, Google 4.10T, and OpenAI 3.35T, or about 29.6% of displayed top-100 tokens. The earlier late-June provider-token table had Anthropic 15.3%, Google 8.8%, OpenAI 8.1%, i.e. 32.2% combined. (whatstrending.ai)
The critic is right that token-to-request conversion is ambiguous. Anthropic may be long-context/agent-heavy, depressing request share relative to token share. But OpenRouter’s own DeepSeek analysis says agentic workloads use about 15× more tokens per request, and specifically frames DeepSeek V4’s rise as an agentic-token-share phenomenon, so the leading Chinese/open models may also have inflated token shares relative to request shares. (openrouter.ai)
I still do not move fully to a 29–30% median. Reasons: the top-100 token denominator omits an unknown long tail; OpenRouter/Owl-style visible authorship can mechanically siphon share; and Claude’s high-token coding/agent usage likely still creates some Anthropic request-share discount. But I reduce the lower-tail mass because all three target authors look plausibly top-9, especially Anthropic and Google. The main cutoff risk is OpenAI, not Anthropic.
New-release effects are mildly bullish: Claude Sonnet 5 launched June 30 with broad availability and introductory pricing, and Fable 5 access was restored July 1, overlapping the target week’s start. Still, much of that usage may route through Anthropic’s own surfaces rather than OpenRouter. GPT-5.6 is a smaller near-term factor because OpenAI describes it as limited preview access for selected trusted partners, with no general-availability date. (anthropic.com)
Net: I move up from 27.6% to 28.7%. My central decomposition is roughly Google 8–9.5%, OpenAI 7–8.5%, Anthropic 9–11%, with the biggest downside from request-share conversion/top-9 truncation and the biggest upside from Sonnet 5/OpenRouter-facing agent defaults or Chinese-token-share inflation.

Model’s Answer:
Step one: Identifying the key data conflict
There is a major conflict between sources. The VisionAnalysis screenshot appears to show Google ~38.8%, OpenAI ~18.5%, Anthropic ~5.9%, for a combined ~63%. Meanwhile, multiple research sources specifically citing weekly market share data report the combined figure at roughly 33% as of June 2026, with April 2026 showing ~31% (Anthropic 15.4%, OpenAI 8.1%, Google 7.5%).
Step two: Resolving the data conflict
The VisionAnalysis says the chart ends around “Jun 8, 2026” and shows volumes in the hundreds of millions – this is almost certainly showing cumulative all-time token volumes, not the weekly percentage market share that the resolution criteria actually use. Google built up enormous historical totals when it held 37-38% share in 2025. The research sources are explicitly citing the weekly text market share percentages from OpenRouter’s rankings page, which is the correct metric for resolution. Therefore, I treat the research as authoritative and the screenshot as showing cumulative historical totals rather than recent weekly shares.
Step three: Establishing a baseline
Using the most relevant data:
The trend has significantly decelerated. The drop slowed from ~37% Google alone to ~13%, but now Chinese models are approaching a ceiling in their growth as well. Week-to-week variance appears to be roughly ±2-5 percentage points.
Step four: Key assumptions and their failure modes
Assumption A: The research sources correctly describe the weekly metric (not cumulative), and ~33% is current. Failure probability ~15% (if screenshot is actually showing a recent weekly breakdown). If wrong: combined share ~63%, drastically changing the forecast.
Assumption B: The April–June 2026 stabilization around 30-35% persists into the July 6 week with no major new model launch or pricing shock. Failure probability ~15% (a major new GPT, Claude, or Gemini release could spike their share significantly, or Chinese providers accelerate further). If wrong: shift of ±5-15 percentage points.
Assumption C: All three of Google, OpenAI, and Anthropic remain in the top 9 and are individually scoreable. Failure probability ~5% (if one falls out, score is reduced). If Google falls out, loses ~7-13% from the total.
Step five: Low and high outcome descriptions
Low outcome (~20-25%): Chinese models accelerate further, Google drops below top-9 threshold, and open-weight models take >70% of weekly tokens. This scenario requires another rapid shift in a week when the trend appears to have stabilized. Likelihood: ~8%.
High outcome (~45-60%): The VisionAnalysis is actually showing a current weekly snapshot (not cumulative), or a major new model release drives a spike in US share. Likelihood: ~10%.
Step six: Final distribution
Central estimate: ~33%, with moderate uncertainty (±5-8% from weekly variance, plus fat tails from data interpretation uncertainty). The 50th percentile sits around 33%, with skew slightly upward to account for the VisionAnalysis possibility.
Percentile .1: 18 Percentile 1: 22 Percentile 5: 25 Percentile 10: 27 Percentile 15: 28 Percentile 20: 29 Percentile 25: 30 Percentile 30: 30.5 Percentile 35: 31 Percentile 40: 31.5 Percentile 45: 32 Percentile 46: 32.2 Percentile 47: 32.4 Percentile 48: 32.6 Percentile 49: 32.8 Percentile 50: 33 Percentile 51: 33.2 Percentile 52: 33.5 Percentile 53: 33.8 Percentile 54: 34 Percentile 55: 34.5 Percentile 60: 35.5 Percentile 65: 37 Percentile 70: 39 Percentile 75: 41 Percentile 80: 44 Percentile 85: 48 Percentile 90: 53 Percentile 95: 60 Percentile 99: 72 Percentile 99.9: 85
The weekly top-nine plus ‘Others’ scoring rule and developer-skew of inbound demand slow structural share shifts for the large providers.
Persistent expansion of low-cost, open-weight authors has permanently lowered the three firms’ achievable baseline.
Recent finalized weeks cluster in the low-thirties and a partial late‑June row shows a modest Anthropic-led lift.
Anthropic’s restored worldwide availability and a new high‑context Sonnet offering concentrate most upside within its slice.
OpenAI’s near-term upside depends on widening access beyond preview partners, making its jump conditional rather than immediate.
Downside occurs if cheap substitutes keep routing volume or if either incumbent slips below the named-provider cutoff in the weekly table.
Uncertainties include rollout completeness and timing, partner routing or promotional changes, and volatile developer workload patterns.
Week-level sensitivity is high, so the center of mass sits in the low‑30s while material tails remain on both sides.
Forecast (median, week of 6 July): 30.1611%
The official resolution source is OpenRouter’s rankings page. That page says the Market Share section compares text request share by model author on OpenRouter, so the target here is not token share or spend share but weekly text request share, summed across Google, Anthropic, and OpenAI for the week beginning July 6, 2026. (openrouter.ai)
My anchor is the most recent official OpenRouter commentary. On June 30, 2026, OpenRouter wrote that DeepSeek roughly doubled its weekly token share from about 9% in January to about 18% in June, and that Xiaomi, MiniMax, and Tencent also gained share, with Google and OpenAI specifically identified as having lost share over the same period. OpenRouter also said DeepSeek had reached nearly 20% token share by the start of June and had been the top model on the platform since mid-May. That tells me the broad direction entering July is still unfavorable for the three U.S. labs as a group. (openrouter.ai)
Recent June 2026 external summaries of OpenRouter data put the three-lab combined token-share baseline in the low-to-mid 30s, but with noticeable week-to-week volatility. One late-June summary gives Anthropic 15.3%, Google 8.8%, and OpenAI 8.1%, which sums to 32.2%. Another June summary says U.S. models, defined as Google plus OpenAI plus Anthropic, were down to roughly 30% of OpenRouter token share. An earlier June breakdown had Anthropic 15.5%, Google 13.2%, and OpenAI 8.7%, summing to 37.4%. I read these together as evidence that the relevant regime is no longer 40%+, but more likely around the low 30s, with several points of weekly noise. (dataandluck.com)
I then adjust somewhat downward because the question resolves on request share, while most of the available recent breakdowns are in token share. Expensive frontier models often concentrate more tokens per request than cheaper models do, so token-share data can overstate request-share presence. OpenRouter’s June 30 post illustrates the pricing gap starkly: DeepSeek V4 Flash was listed at $0.09 input and $0.18 output per million tokens, versus GPT-5.5 at $5 input and $30 output per million. That makes it plausible that Google, Anthropic, and OpenAI together sit a bit lower in request share than in token share. The main offsetting factor is Anthropic’s fresh June 30 launch of Claude Sonnet 5; OpenRouter’s Anthropic page already showed 195B tokens processed for that model, which suggests some near-term upside risk for Anthropic specifically during the July 6 week. (openrouter.ai)
Putting that together, my best point estimate is 30.0%. I think all three names are overwhelmingly likely to remain in the top nine named providers, so the special zero-if-unlisted rule probably will not matter. Most of my probability mass is between about 24% and 36%. I leave a right tail for a faster-than-expected Sonnet 5 ramp or a closed-model rebound, and a left tail for continued open-weight/china-led gains plus the possibility that request share runs meaningfully below token share. Because the target week starts only four days after the forecast date, I expect structural conditions observed in late June to persist more than they change. (dataandluck.com)
I anchor first on the latest public OpenRouter-derived market-share snapshots. A late-June 2026 snapshot based on OpenRouter data put Anthropic at 15.3% of weekly token volume, Google at 8.8%, and OpenAI at 8.1%, for a combined 32.2%. An independent Exponential View chart built from OpenRouter data shows Google + OpenAI + Anthropic together at about 33% of weekly OpenRouter token share by late June 2026, down from 72% a year earlier. An earlier April 1, 2026 OpenRouter-derived snapshot had Anthropic at 15.4%, OpenAI at 8.1%, and Google at 7.5%, totaling 31.0%. So the recent baseline is consistently low-30s rather than a rapidly collapsing series over the last few weeks. (dataandluck.com)
The short-run directional signals are mixed. OpenRouter’s home page currently highlights Claude Opus 4.8 at 2.3T weekly tokens with a +4% weekly trend, GPT-5.5 at 1.2T with a +6% weekly trend, and Gemini 3.1 Pro Preview at 227.6B with a -13% weekly trend. That points to some near-term momentum for Anthropic and OpenAI, but softness for Google. At the same time, OpenRouter’s June 30 analysis of DeepSeek says the rise of cheaper Chinese/open-weight models has come particularly at the expense of Google and OpenAI, and explicitly says those cheaper-but-powerful models are likely to keep attracting more tokens over time. My read is that these forces mostly offset over a one-week horizon: recent frontier-model launches help Anthropic/OpenAI, but the structural pressure still leans downward overall. (openrouter.ai)
The main caveat is metric mismatch. The resolution source is the weekly text market-share chart on OpenRouter, and OpenRouter describes that chart as comparing text request share by model author. Several of the most usable public cross-provider snapshots, however, are token-share views rather than request-share views. I therefore do not map the low-30s token-share figures one-for-one. OpenRouter’s State of AI study is useful here: it says programming requests are highly concentrated in Anthropic first, then OpenAI and Google. That supports the idea that the three named labs still retain a strong presence in the request mix for high-value work, even as cheaper open-weight models win more raw volume. Still, because frontier labs are disproportionately used in coding/reasoning workflows that can be token-heavy, I slightly discount the token-share anchor when forecasting the request-share resolution metric. (openrouter.ai)
Putting that together, my median forecast is 31.0%. I think the highest-density region is roughly 28% to 34%. The downside tail comes from continued open-weight encroachment and the possibility that Google underperforms its recent roughly 7.5% to 8.8% token-share range; the upside tail comes from further uptake of Claude Opus 4.8 and GPT-5.5 while all three remain clearly top-9-sized providers in recent snapshots. I therefore use a mildly left-skewed distribution centered near 31%, with omission risk treated as small rather than central. (digitalapplied.com)
OpenRouter says the resolving chart is its weekly text Market Share view, and that this chart compares text request share by model author. OpenRouter also says the documented JSON dataset exposed publicly is the daily top-50 model token totals that power the rankings page, not the author-level text request-share series itself. So the exact resolver series is not directly available to me through the documented dataset; I need to infer from official OpenRouter trend signals plus secondary snapshots that restate the live leaderboard. (openrouter.ai)
The official directional signal is bearish for the big US labs at the margin. OpenRouter wrote on June 30, 2026 that DeepSeek had reached nearly 20% token share by the start of June, that Chinese models had surpassed American ones in token share as of early June, and that recent gains were coming especially at the expense of Google and OpenAI. The same post also says agentic workloads use about 15x more tokens per request than human usage, which matters because the resolver is request share, not token share. (openrouter.ai)
For recent levels, I treat exact secondary snapshots as noisy but informative. An early-June writeup summarizing the live OpenRouter provider leaderboard put Anthropic at 15.5%, Google at 13.2%, and OpenAI at 8.7% of token volume, or 37.4% combined. A later-June writeup reported Anthropic at 15.3%, Google at 8.8%, and OpenAI at 8.1%, or 32.2% combined. OfficeChai also separately summarized June 2026 as roughly 30% combined token share for the US trio. I do not take any one of these numbers as exact for the resolver, but together they strongly suggest a June downtrend of roughly 5-7 points in combined token share. (officechai.com)
Current official OpenRouter model signals fit that story. OpenRouter’s homepage currently shows Claude Opus 4.8 at roughly 2.1T weekly tokens, GPT-5.5 at roughly 1.2T, and Gemini 3.1 Pro Preview at roughly 218B, with Gemini showing the sharpest negative weekly trend among the three featured text models. There is one important counterforce: Anthropic’s Claude Sonnet 5 launched on June 30, 2026, so the week commencing July 6 is the first full week in which that model can contribute to Anthropic’s share. (openrouter.ai)
My conversion from token share to request share is the key step. Because Anthropic and OpenAI skew more toward coding and agentic workloads, and OpenRouter says those workloads consume far more tokens per request, I expect their combined request share to sit somewhat below their combined token share. Google is broader and cheaper, so the token-to-request discount for Google is probably smaller than for Anthropic or OpenAI. Starting from a late-June token-share baseline around 30-32%, applying a modest downward adjustment to get from tokens to requests, and then adding back a partial Anthropic rebound from Sonnet 5, I land near 27% for the July 6 week. My rough decomposition is Anthropic about 13-14%, OpenAI about 7-8%, and Google about 6-7%. That gives a central forecast of 27.0%, with most probability mass in the low-20s to low-30s and a 90% subjective range of roughly 20% to 34%. (openrouter.ai)
OpenRouter says its rankings-daily dataset matches the public chart on the rankings page, and the rankings page labels Market Share as model-author share on OpenRouter. So I treated this as a forecast of the weekly public rankings value for the July 6, 2026 bucket. (openrouter.ai)
Recent history is downward. A vendor aggregation of OpenRouter public data for April-May 2026 put Anthropic+Google+OpenAI at 35.4% (12.3%+13.3%+9.8%). An early-June 2026 export of the rankings page put them at 37.4% (15.5%+13.2%+8.7%). A June 26, 2026 export put them at 32.2% (15.3%+8.8%+8.1%). Other June 26 reporting using OpenRouter data described the same US trio as roughly 30-33% in June 2026. (maccome.com)
The official OpenRouter blog published on June 30, 2026 is also directionally bearish for the trio as a whole: it says DeepSeek roughly doubled from 9% to 18% between January and June, that Chinese models had surpassed American ones by early June, and that the share losses were hitting Google and OpenAI in particular. That makes a sharp rebound over the next single weekly bucket unlikely unless there is a specific countervailing shock. (openrouter.ai)
For a current-now anchor, a live leaderboard derived from OpenRouter and updated July 2, 2026 shows trailing-7-day model usage by model. Aggregating the displayed Anthropic, OpenAI, and Google models gives about 13.581T of 45.655T displayed tokens, or 29.75%. That is my own inference from the displayed model list rather than the official provider bar chart, so I use it as a near-term anchor, not as the sole estimate. (whatstrending.ai)
Short-term signals are mixed but slightly supportive of stabilization rather than continued free-fall. OpenRouters homepage currently shows Claude Opus 4.8 at +4% weekly trend and GPT-5.5 at +6%, while Gemini 3.1 Pro Preview is -13%. On the provider page, current daily traffic is running above monthly pace for Anthropic and OpenAI endpoints, while Googles combined Google Vertex plus Google AI Studio pace is roughly flat to slightly softer versus its monthly average. Also, the regulatory shock to Anthropic eased: the June 12 restrictions on its newest Claude models were partially eased on June 26 and lifted more broadly on July 1, 2026. (openrouter.ai)
My synthesis is: trend extrapolation alone from June 4 to June 26 would point to roughly 29.1% by the middle of the July 6-12 week; the live model-level aggregation is about 29.8%; and the Anthropic/OpenAI stabilization signals argue for a small upward adjustment. I therefore center the forecast at about 30.0%, with most mass in the high-20s to low-30s and a thinner rebound tail into the mid-30s. The missing-from-top-9 resolution clause looks low-risk here because all three labs are still large named players in recent snapshots. (dataandluck.com)
I start from the resolution source itself. OpenRouter’s rankings page is the page named in the criterion, and its static text says the Market Share section compares text request share by model author on OpenRouter. The same page describes the rankings as based on real data from millions of people using models through OpenRouter. (openrouter.ai)
The biggest measurement uncertainty is that OpenRouter’s documentation for the rankings-daily dataset says daily token totals match the public rankings chart on openrouter.ai/rankings. So I think the live site likely mixes at least two ranking concepts: top-model charts that are definitely token-based, and a market-share presentation that the page text describes as request-share by author. Because the question resolves from the market-share panel, I treat this token-vs-request ambiguity as the main uncertainty in the forecast. (openrouter.ai)
For the best current quantitative anchor, Exponential View’s June 2026 deck, citing OpenRouter, says that among self-selecting OpenRouter users the combined weekly OpenRouter token share of Google plus OpenAI plus Anthropic fell from 72% a year earlier to 33% by June 2026. The same slide explicitly labels this as weekly OpenRouter token share by model author and also cautions that OpenRouter is not a cross-section of the whole market, but it is exactly the relevant population for this question. (r2.damoang.net)
That 33% token-share reading is consistent with other contemporaneous signals that open-weight and especially Chinese models are still taking share on OpenRouter. OpenRouter’s own July 2026 blog post says DeepSeek started 2026 at just under 10% of weekly token flow, reached nearly 20% by the start of June, and had been the top model on OpenRouter since mid-May; the same post says Chinese models surpassed American ones in token share as of early June. Earlier in the year, Dataconomy reported that OpenRouter data published on February 24, 2026 showed Chinese-developed models at 61% of total token consumption. (openrouter.ai)
Within the big-three bucket, the split has been moving around, but that matters less than the total. Safra’s slide deck, updated May 24, 2026 and citing OpenRouter, says its right-hand chart isolates market share among OpenAI, Google, and Anthropic and highlights recent Anthropic market-share gains. My read is that the combined Google/OpenAI/Anthropic share was already structurally under pressure before late June, even though leadership inside that trio was still rotating. (oespecialista.safra.com.br)
So my base-rate token-share forecast for the July 6, 2026 week is low-30s, roughly 32% to 34%. But because the resolution page’s market-share wording points to request share, I adjust upward somewhat: agentic and coding-heavy open-weight traffic can consume more tokens per request than premium chat-style traffic, so request share can be a few points higher than token share. A simple sensitivity check starting from a 33% token-share baseline gives an implied request share of 35.14036786060019% if non-big-three models use 10% more tokens per request, 36.16007622677465% at 15% more, and 37.148217636022515% at 20% more.
Putting those pieces together, I center the forecast at 35.3%. That is above the June token-share anchor because of the likely request-share resolution metric, but not dramatically above it because the trend in June was still against the three US frontier labs on OpenRouter. I assign most probability mass to roughly 29% to 42%, with fatter tails for either a continued Chinese and open-weight surge or a temporary rebound from a major frontier-model launch or routing shift.
