Key facts and constraints:
Synthesis of analyst views:
Resulting distribution (conceptually): concentrated on the four release dates, with cumulative probability by 2026-08-07 around ~80–85%, and ~15–20% probability that no qualifying release appears by the 2026-08-12 cutoff (open-after). This implies p90 and above should be placed strictly past 2026-08-12 to correctly represent the open-after mass.
An amateur forecast is likely to (a) extrapolate the latest MoM increase and overconcentrate on the very next checkpoint date, or (b) ignore the discrete Cox publication schedule and incorrectly spread probability across arbitrary days, or (c) anchor percentiles at the 2026-08-12 bound instead of placing them past-bound to represent “miss in-window.” My forecast explicitly concentrates mass on the plausible publication dates and encodes a material open-after tail (without stacking at the bound), while moderating overly aggressive mid-June crossing assumptions. Confidence is moderate: the main remaining uncertainty is short-term EV wholesale volatility vs. summer/supply headwinds.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the reasoning is dominated by release mechanics and recent trend strength:
Overall, the forecasts expect the Manheim EV Index to cross 218.0 on a scheduled summer release, with July 8 and August 7, 2026 emerging as the central dates. The shared logic is that strong recent growth likely puts the index near the threshold, but uncertainty about the current level keeps open a meaningful chance of delay beyond the immediate summer window.
— Iteration 2 — Across the forecasts, the core reasoning is highly similar:
The collective view is that the EV Index is more likely than not to reach 218.0 within the next several scheduled Manheim releases, with probability mass concentrated on the mid-June through early-August reporting dates. At the same time, the forecasts retain a sizable tail into later 2026 in case seasonal EV price softness prevents an immediate crossing.
— Iteration 3 — Across the forecasts, the reasoning is driven by two main themes: release cadence and recent EV Index momentum.
The collective view is that the Manheim EV Index is most likely to first hit 218.0 or higher on a scheduled release date clustered around July, with mid-June as an earlier but less certain possibility, and a meaningful tail into August if the trend slows or the threshold is not yet met.

Forecaster 3: Probability distribution:
The research found that the latest full-month Manheim EV Index update (May 2026, published June 5, 2026) reported the EV Index was up 11.9% year-over-year and 3.5% month-over-month while the overall Manheim Used Vehicle Value Index (MUVVI) was 212.6; mid-month and prior-month updates (mid-May, April, March 2026 and several 2025 months) show an accelerating trend for EV wholesale values (examples cited: April 2026 +7.2% YoY, mid-May +11.4% YoY, June 2025 +12.1% YoY), EV weighting in the index reached record levels (about 3.3–3.9%), and drivers noted include elevated gasoline prices, stronger EV demand, and growing off-lease EV supply. Publication cadence is monthly (typically the 5th business day of the following month) with mid-month checkpoints, giving multiple release opportunities (mid-June, full June, mid-July, full July) before the August 12, 2026 resolution deadline.
A critical gap identified by the research is that published Manheim materials cited in the search report percentage changes for the EV Index but did not state the EV Index’s absolute numerical value, so the research could not confirm whether the index was already at or above the 218.0 threshold; searches of prediction-market platforms (Manifold, Metaculus, Polymarket) did not surface any active markets on this specific question. Sources used in the research included Manheim / Cox Automotive monthly and mid-month market reports and related Cox Automotive commentary, plus checks of prediction-market websites.

Reading: strict
The resolution criteria are highly specific and literal: the qualifying value must be numerically stated, must be seasonally adjusted, must be for the newest-dated data point, must appear in the release text or a named chart (not the downloadable file), and the publication date must be publicly verifiable to daily precision from the release’s first public appearance. There is no room for charitable interpretation — every condition is tightly defined with explicit exclusions.

Evidence confidence: medium
medium evidence]The EV Index rose ~3.1–3.5% in May; a similar rate of gain in June would bring the index from ~212.5 to approximately 219–220. The mid-June release has historically included an explicit numerical EV Index value (as seen in mid-May at 211.7). If EV market momentum continues, this is the earliest qualifying date.
Monthly gains can decelerate; the full-month May figure may itself have declined from mid-May (211.7), meaning the starting point for June is lower. A gain of only ~2.6% from ~212.5 is needed, but if the June trajectory is slower (e.g., +1–2%), the mid-June value could be 215–217, below threshold.
high evidence]Even if mid-June slightly misses, continued upward momentum would likely push the full-month June figure above 218.0. The recent pace of gains (~3% per month) over two months from ~212.5 would produce ~225+. A moderate deceleration to ~1.5–2% for mid-June and a continued pace for full June could still hit the threshold by July 8.
If EV market prices reverse course or decelerate sharply below 218.0 by June, the full-June release would also miss the threshold. Additionally, whether the absolute EV Index level will be stated numerically in the July 8 release is uncertain (the June 5 release only stated percentage changes, not the absolute level).
medium evidence]If momentum slows in June but persists modestly through July, the threshold could be crossed later. The p75 projection is ~225.8, suggesting a wide range of possible dates. Seasonal patterns or tariff-related pricing shifts (sources 12, 13 note elevated prices vs. prior year) could be uneven month-to-month.
If the EV Index continues at its recent pace, it would likely cross 218.0 earlier (June or July 8 releases); these later dates represent a scenario where the pace of EV price gains has materially slowed relative to the March–May trend.
low evidence]The p10 projection is ~210.4, suggesting meaningful probability that the index remains below threshold through the window. If EV market conditions deteriorate (demand shock, increased supply, tariff reversal), prices could fall. Furthermore, if future releases follow the June 5 pattern of reporting only percentage changes without the absolute EV Index level numerically, no qualifying release would be published even if the index level is above 218.0.
Recent trend has been strongly upward; the index is approximately 5.5 points (2.6%) below threshold with 4 releases remaining. The p10 of 210.4 requires approximately no gain or a decline from current levels, which contradicts the observed trend. Multiple release formats (mid-month and full-month) provide multiple opportunities.
inside_view_v1)Inside View Causal Analysis
Current state → decision chain:
The EV Index was 211.7 at mid-May 2026 (source 17), with derived full-month May at ~212.5 (source 6). The threshold of 218.0 requires ~2.6% additional gain from ~212.5.
Key causal mechanisms:
- Price momentum: March +3.7%, April +1.4%, mid-May +3.1%, full-May +3.5%. The trend is strongly upward, with the March/May rates well above the required 2.6% gap.
- Release schedule: 4 qualifying releases before Aug 12 deadline — June 17, July 8, July 17, Aug 7 (source 7).
- Survival projection: Median projected EV Index after 4 periods ≈ 220.5, with 218.0 threshold between p25 (~215.2) and p50 (~220.5) (source 8). This is strong quantitative evidence — tagged high.
- Qualification format risk: June 5 release stated only % changes, not absolute level. Mid-May did state “211.7” numerically. Both release types can qualify via chart label even when release text omits absolute level.
Scenario weighting by evidence strength:
Scenario: July 8 full-June release (high evidence strength): This is the most likely resolution bin. Even if mid-June (June 17) misses because the index sits just below 218, the full-June index would likely cross given recent momentum. The high-evidence survival projection has median ~220.5 after 4 periods, with threshold below median. The July 8 release falls in Jul 04–Jul 12 (bin_3). Assigning heaviest mass here.
Scenario: June 17 mid-June release (medium evidence strength): If June monthly gain mirrors May’s +3.5%, the mid-June index would be ~213–215 (2 weeks into June), potentially already at 215–217, possibly 218+. Given mid-May was explicitly stated as 211.7 and full-May estimated ~212.5, a half-month further gain of ~2.5–3% could reach 218. Probability is moderate. June 17 falls in Jun 18–Jun 26 (bin_1)… wait, June 17 is in Jun 10–Jun 18 (bin_0). Bin_0: Jun 10–Jun 18 covers June 17.
Scenario: July 17 or Aug 7 (medium evidence strength): If June gains are mild, this covers the catch-up. July 17 falls in Jul 12–Jul 19 (bin_4); Aug 7 falls in Aug 04–Aug 12 (bin_7).
Scenario: No qualifying release by Aug 12 (low evidence strength): p10 of 210.4 implies some chance of below-threshold, plus format risk. But recent trend strongly argues against.
Bin mapping:
- Jun 10–18, includes June 17 mid-June release (bin_0): medium scenario → 20%
- Jun 18–26 (bin_1): no release dates in this window → ~0%
- Jun 26–Jul 4 (bin_2): no release dates → ~0%
- Jul 4–12, includes July 8 full-June release (bin_3): high scenario → 35%
- Jul 12–19, includes July 17 mid-July release (bin_4): medium scenario → 15%
- Jul 19–27 (bin_5): no release dates → ~0%
- Jul 27–Aug 4 (bin_6): no release dates → ~0%
- Aug 4–12, includes Aug 7 full-July release (bin_7): medium scenario → 12%
- Aug 12–Oct 14 (bin_8): resolves as >Aug 12 if no qualifying release → low scenario → 10%
- bin_9 to bin_12: small residual for uncertainty about never resolving or very late → 4% spread thin
The format qualification risk (absolute level not always stated) creates moderate uncertainty, but chart labels also qualify, and mid-month releases have historically stated the numeric value. I’ll keep most mass in the near-term bins.

outside_view_v1)Reference class: month-to-month moves in the Manheim EV Index (recent 2026 months) and historical probability that an index ~2.6% below a threshold reaches that threshold within the next four Manheim release opportunities. Base rate: ~60% — the Research Brief’s survival/hazard projection (using recent observations ~205.3, 211.7, ~212.5) produced a median projected EV Index ≈220.5 after four releases with the 218.0 threshold between the p25 (~215.2) and p50 (~220.5) (source 8). Adjustment: +15 percentage points to reflect (a) multiple scheduled publication opportunities before the 2026-08-12 cutoff (June 17 mid-June, July 8 full-June, July 17 mid-July, Aug 7 full-July — source 1/7), (b) the recent strong monthly gains in 2026 (+3.1–3.5% in May; March/April gains also positive — sources 5,6), and (c) the outside-view conservatism that favors the base-rate. I subtract modest probability for non-qualification because the June 5 release pattern (June 5 full-month) showed only percentage changes and did not print the absolute EV Index value in the release text (source 11), and the strict resolution rules require an explicit numeric seasonally adjusted EV Index in text or a labeled chart value. Final event-by-deadline probability: ~75% that a qualifying release (EV Index ≥218.0, printed numerically in release text or chart label) appears on or before 2026-08-12; ~25% that no qualifying release is published by that date (resolves >2026-08-12). Distribution across specific publication-date bins (weights reflect the scenario evidence strengths in the Research Brief): - Jun 10–18 — mid-June, June 17 (bin_0): 15%. Rationale: medium evidence (Research Brief scenario tagged medium). If monthly gain repeats ~3% in early June, mid-June could cross 218 (sources 5,6,8,17). - Jul 04–12 — full-June release dated July 8 (bin_3): 45%. Rationale: high-evidence scenario in the brief (relative_evidence_strength = high). The survival projection’s median outcome and the multi-period opportunity strongly point to the July 8 full-month release as the likeliest first qualifying publication (source 8), though there is some risk the release will omit a numeric absolute value (source 11). - Jul 12–19 — mid-July, July 17 (bin_4): 10%. Rationale: medium evidence; plausible if mid-June misses but momentum carries into July (Research Brief scenario medium). - Aug 04–12 — full-July release dated Aug 7 (bin_7): 5%. Rationale: medium evidence but later in window; assigned smaller mass because earlier scheduled releases are more likely to be the first crossing. - Aug 12–Oct 14 (bin_8): 25%. This captures the Research Brief’s low-evidence but non-negligible scenario that no qualifying release appears by the Aug 12 cutoff (p10-style tail and the reporting-format risk noted in sources 11–13 and scenario tag low). Other bins set to zero because scheduled qualifying releases fall on the bins above and unscheduled publication is less plausible; the distribution is intentionally wider than an inside-view point estimate because the brief flagged uncertainty about whether Cox will print absolute EV Index levels in future releases (confidence_in_evidence = medium) and the resolution’s strict requirement that the numeric level appear in text or on the chart (source 11). Key evidence cited inline: mid‑May EV Index = 211.7 (numeric in mid‑May release) and derived full‑May ≈212.5 (sources 17, 6); June 5 full‑month release reported % changes but not the absolute EV number in text (source 11); scheduled qualifying release dates are June 17, July 8, July 17, Aug 7 (source 1/7); survival/hazard projection median ≈220.5, p25 ≈215.2, p10 ≈210.4 (source 8). Given the brief’s medium confidence in evidence and the strict resolution criteria (numeric value required in release text/chart), I intentionally preserve substantial mass (25%) for the possibility that no qualifying, verifiable numeric publication occurs by 2026-08-12.
contrarian_v2)Adversarial reading
The bulk of the evidence, especially the high-strength scenario and the survival/hazard projection (median 220.5 after four releases, 218.0 between p25 and p50), pulls toward crossing the threshold on the July 8 full-June release (bin_3), with secondary support for the June 17 mid-month release.
Counter-evidence found (or absence)
The June 5 full-month May release (sources 11, 12, 13) reported only percentage changes and omitted any absolute numerical EV Index value in the release text or chart label; the downloadable file is explicitly excluded for resolution. Mid-May did state 211.7 numerically, but the pattern of non-numerical reporting creates a material risk that later releases will also fail to qualify even if the index exceeds 218.0. This is substantive counter-evidence that the high-evidence July 8 scenario under-weights.
Distribution implications
The absolute-value reporting barrier and the p10 projection (~210.4) justify shifting mass away from the early bins (especially bin_0 and bin_3) relative to naive consensus and toward the post-deadline bins (bin_8 and later), increasing terminal probability by roughly 25–30 percentage points versus a projection-only reading.
Strategy: logit_mean • Drafts: 3/3
anchoring_v1The draft places ~16.5% mass on June 10–18, capturing the June 17 mid-June release (bin_0) and ~35.7% on July 4–12, capturing the July 8 full-June release (bin_3), making bin_3 the modal bin. This is anchored to the EARLIEST plausible timing under the survival projection (which uses a strongly optimistic 3–3.5%/month trend) rather than treating the modal expectation neutrally. Specifically, the survival projection’s median of ~220.5 after FOUR releases is being used to justify placing over 50% of mass on the first two of those four releases — this treats the front-of-window as the modal outcome rather than acknowledging the threshold falls between p25 and p50, meaning roughly 25–50% of outcomes would clear it on the first opportunity (not 50%+ combined across first two). Additionally, the June 17 bin’s ~16.5% mass is anchored to the most optimistic interpretation of “if monthly gain repeats ~3% in early June” — the mid-month release captures only the first ~2 weeks of June data, not a full month’s gain, so projecting a full +3% to that mid-month point is optimistic. The draft also underweights the qualification format risk: the June 5, 2026 full-month release (the most recent full-month release) omitted the absolute EV Index level, meaning the July 8 full-June release may similarly fail to qualify, but the draft treats this risk qualitatively as only a modest drag.
ceiling_v1The core structural constraint the forecaster partially integrated but under-weighted is the discrete release schedule ceiling: there are exactly 4 qualifying release dates before the Aug 12 deadline (June 17, July 8, July 17, Aug 7), and resolution can only fall on one of those 4 dates or the terminal “>Aug 12” bin. The bins with zero qualifying releases (bin_1: Jun 18–26, bin_2: Jun 26–Jul 4, bin_5: Jul 19–27, bin_6: Jul 27–Aug 4) cannot resolve the question — yet the draft places ~0.9% total mass in each of these four empty bins (~3.6% total), which violates the hard structural constraint. More importantly, the “reporting format” risk is a second structural constraint: the June 5, 2026 full-month release explicitly did NOT state the absolute EV Index level numerically (sources 11, 12, 13), only percentage changes. If full-month releases consistently omit the absolute level, then July 8 (bin_3) and Aug 7 (bin_7) face a material disqualification risk that isn’t fully reflected. The survival projection’s median of ~220.5 addresses only the level question, not the qualification format question — these are independent constraints that must be multiplied. If the format failure probability on full-month releases is ~40–50% (1 full-month failure observed out of 1 full-month attempts), then bin_3’s ~35% should be discounted to ~18–21%, and bin_7’s ~10% to ~5–6%.
math_v1The draft distribution sums to 1.0 (verified: all probabilities across 13 bins sum to exactly 1.0). However, there is a significant internal inconsistency between the stated rationale and the shape of the distribution. The rationale cites the survival/hazard projection median of ~220.5 after four periods (with 218.0 between p25 ~215.2 and p50 ~220.5) as “strong quantitative evidence” and tags the July 8 full-June release scenario as “high evidence strength.” Yet the distribution assigns only 35.7% to Jul 04–12, which contains July 8 (bin_3). By contrast, 18.6% flows to Aug 12–Oct 14, the “resolves after deadline” bin (bin_8), and 16.5% to Jun 10–18 (bin_0). If the median projection implies the threshold is crossed by the July 8 release in the typical case, the modal bin should receive substantially more than 35.7%, and the post-deadline bin (bin_8) should receive less than 18.6%. The distribution appears to have been pulled downward in the near-term bins and shifted toward the tail, contrary to what the “high evidence” quantitative projection implies.
Reviews consumed: 3
The anchoring reviewer flagged that mass on the earliest bins is too optimistic and format risk for full-month releases is underweighted (shift_lower). The ceiling reviewer flagged the structural empty-bin constraint (bins 1,2,5,6 contain no release dates) and emphasized full-month format disqualification risk, suggesting a redistribute with more mass on bin_8 and mid-month bins. The math reviewer pointed in the opposite direction (shift_higher), arguing bin_3 should hold more mass given the survival median ~220.5 and that bin_8 at 18.6% is inflated relative to the projection’s p10. I weighed these: I accepted the ceiling reviewer’s empty-bin structural constraint (zeroing bins 1,2,5,6 except trivial floor) since no release dates fall there. I partially accepted the anchoring/ceiling format-risk concern, keeping bin_8 elevated. I partially accepted the math reviewer’s point that bin_3 deserves the modal weight given the high-evidence projection, but did not boost it as aggressively as 47% because the format risk on full-month releases (June 5 omitted absolute level) is a legitimate offset. Net: redistributed empty-bin mass mostly to bin_3 and bin_8, kept mid-June, which historically prints numeric value (bin_0) reasonably weighted.
[math] bin_3 should be ~47% and bin_8 reduced to ~11% based on survival projection median 220.5

Model’s Answer: Step one is to pin down the discrete resolution dates. This question cannot resolve on arbitrary days; it can only resolve on the publication dates of qualifying official Cox/Manheim releases. From the 2026 release pattern in the research, the full monthly reports appear to land on the fifth business day after month-end, which strongly points to 2026-07-08 for the June report and 2026-08-07 for the July report. The mid-month checkpoints appear about three business days after the 15th, which makes 2026-06-18 and 2026-07-20 the best inferred checkpoint dates.
Step two is to estimate where the EV Index likely stands now. The strongest source trail suggests the EV Index was about 202.4 in March, then roughly 205.2 in April, about 211.6 at mid-May, and about 212.4 in the full May report. That means the threshold of 218.0 is still about 2.6% above the latest likely full-month value.
Step three is to think about how fast it can plausibly get there. EVs have clearly been outperforming, and higher gasoline prices are supportive, so a June or July crossing is plausible. But 218 is not already “at the doorstep” in the official snippets, and the language around the broader Manheim index is still “moderate rise” rather than a blowoff move. That makes the mid-June checkpoint possible but still distinctly unlikely, the early-July full June report a serious candidate, the mid-July checkpoint slightly later but still plausible, and the early-August full July report another meaningful possibility. There is also still a substantial chance it simply does not get there by the Aug. 12 resolution cutoff.
The assumptions that matter most are whether the May EV Index estimate of roughly 212.4 is basically correct, whether the release cadence continues in the same pattern, and whether EV price momentum remains strong through June and July rather than flattening. I’d put the chance that the May level is materially off at about 20%, the chance the release-date pattern slips by a day or two at about 25%, and the chance that recent EV momentum fades enough to prevent a crossing by Aug. 12 at about 35%. Those risks are why I keep a large tail on the later-than-cutoff outcome.
An earlier outcome would most likely come from a very strong June checkpoint, with gasoline-price support and continued EV outperformance pulling the seasonally adjusted EV index above 218 already by mid-month. I think that is possible but only around a 10% kind of outcome. A later outcome would come from more ordinary month-over-month appreciation, where EV values keep rising but not fast enough to clear 218 until after the Aug. 12 cutoff, or perhaps do not clear it at all in the observed window. I think that later-than-cutoff path is still roughly one-third likely.

Seasonal calendar, sparse monthly history, and rounded public reporting constrain when a threshold can be observed.
Mid-month checkpoints and monthly releases are the formal windows for a qualifying label to appear, concentrating opportunity on June 17 and the early July monthly date.
Recent three-month momentum—consecutive gains in March through May—makes the modest percentage increase now needed readily attainable.
Market-side forces—still-elevated gasoline prices and tight used-EV days’ supply—bias wholesale EV values upward, while muted dealer sentiment and rising off-lease supply limit runaway upside.
A mid-June checkpoint is the most likely immediate inflection because it can display a labeled EV Index value before the June monthly report.
If mid-June falls short, the June monthly and mid-July snapshots provide follow-on chances, but historical patterns show July rarely fully rescues a weak June.
Key uncertainties include the short, regime-shifting EV series, the possibility that public labeling or rounding conventions change, and the timing of off-lease EV flows into wholesale channels.
Near-term sensitivity is highest to gasoline prices and rapid shifts in dealer bidding; those factors can flip a modest required move from unlikely to plausible within weeks.
Forecast (median): around 2026-07-21 for the next Manheim EV Index release to show a seasonally adjusted EV Index ≥ 218.0.
Question: will Cox/Manheim’s next eligible EV Index reading exceed the 218.0 threshold before 2026-08-12? The latest listed May 2026 EV Index is 212.6, so the next qualifying datapoint must gain +5.4 points (~+2.5%). Forecasters mostly agree this is plausible given strong early-2026 momentum—May was +3.5% MoM—tight used-EV days’ supply, rising used-EV sales, and high gasoline prices that Cox links to stronger dealer bidding. Important cautions shared across teams are that the recent upswing is a short, possibly shock-driven regime (218+ was mainly a pandemic-era phenomenon), mid-month checkpoint values can be noisy, and Cox warns of rising off-lease EV supply into summer that could cap prices. The consensus places meaningful probability mass on a June crossing (mid-June + June full-month/Q2) with additional, smaller chances in July, while retaining a substantial no-event tail; one provided probability split was mid-June 20%, June full-month 27%, mid-July 8%, July full-month 14%, and no qualifying release by Aug. 12 about 31%. Forecasters differ little on mechanisms and timing; disagreement is mainly about how persistent the recent momentum will be versus incoming off-lease supply pressure.
