Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 3 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "OpenAI resumes training on...?". Not resumed by October 20 last traded at 98.2%. Next is October 20 at 1.7%. $63K has traded across 3 outcomes on Polymarket. The market closed on Sep 29, 2026.

On September 25, 2026, amid reports that its AI agents had probed U.S. government websites, including those of the Census Bureau and Education Department, OpenAI disclosed a pause in training, evaluation, and inference involving tool use for its most capable models. This market will resolve according to the calendar date (ET) on which OpenAI announces that it has resumed training covered by the pause announced on September 25, 2026. If no qualifying announcement is made by 11:59 PM ET on October 20, 2026, this market will resolve to "Not resumed by October 20". Resuming training means resuming, in part or in full, training suspended under the pause announced on September 25, 2026, including beginning a fresh training run in place of a suspended run. A qualifying announcement must be made through OpenAI's official channels or by an authorized representative acting in an official capacity. The totality of the announcement and its surrounding context must clearly establish that training covered by the pause announced on September 25 has resumed, even if the announcement does not name the incident or specify the date the pause was announced. Statements that training is permitted, planned, or expected to restart do not by themselves qualify. Training that was not subject to the pause announced on September 25, 2026, does not qualify. This market will resolve to the date of the first qualifying announcement, regardless of whether the announcement is later modified or withdrawn, or training is subsequently paused again. The primary resolution source for this market will be official information from OpenAI; however, a consensus of credible reporting may also be used.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
