What the market asked
The Polymarket event was framed as “Ethereum above ___ on August 13?” — a crypto threshold question about where ETH would sit on a specific date. Resolution, as the council noted, was strict: the close of the Binance spot ETH/USDT 1-minute candle at 12:00 PM Eastern Time (16:00 UTC) on August 13, 2026. Among the related outcomes, the graded line was whether Ethereum would be above $1,600 on that date.
What the council concluded
All four models — Gemini, Grok, Claude, and GPT — participated, with Grok as chairman. The council’s formal action was BUY_YES, with an assigned probability of 34% and confidence of 70%. Its published reasoning was brief and procedural:
Council recommends BUY_YES (YES). Probability: 34%, Confidence: 70%. Resolution is strictly the close of the Binance spot ETH/USDT 1-minute candle at 12:00 PM Eastern Time (16:00 UTC) on August 13 2026.
Separately, under the most-likely framing used for grading, the council identified “Will the price of Ethereum be above $1,600 on August 13?” as the standout outcome and assigned it 100%. That most-likely call is what the grade is based on.
What the market itself was pricing
The report does not include an independent Polymarket mid or order-book snapshot beyond the council’s own numbers. What we have is the council’s dual signal: a BUY_YES stance paired with a 34% probability figure and 70% confidence on the recommendation, alongside a 100% most-likely weight on the above-$1,600 threshold. In other words, the models treated “above $1,600” as effectively the resolved state they expected, even while the headline BUY_YES probability on the broader action sat at 34%.
What actually happened
The winning outcome was exactly the council’s graded pick: Ethereum above $1,600 on August 13. The council was marked correct. Graded on the most-likely basis, the pick probability of 100% against a binary win produced a Brier score of 0.0 — a perfect score on that call. No partial credit or near-miss dynamics applied; the threshold that the council treated as certain was the one that paid.
Takeaway
This was a clean hit on a single-day crypto level. The interesting tension in the record is internal: a modest 34% BUY_YES probability and 70% confidence next to a 100% most-likely tag on the $1,600 line. When grading follows the most-likely outcome, a full-probability call that matches reality will always print a Brier of zero — which is what happened here. The result does not prove the council can repeatedly pin ETH levels; it shows that on this dated threshold, with a hard Binance 1-minute close rule, the models’ top pick and the market’s resolution lined up completely. Future reports will show whether that alignment is skill or a one-off on a relatively low bar for the asset.
