This PredictPedia contract is a Polymarket event titled "Which company has the best AI model on LiveBench (Mathematics) end of October?" [1]. The rules say it will resolve according to "the company which owns the model with the highest Mathematics score on LiveBench.ai when the leaderboard is checked on October 31, 2026, at 12:00 PM ET" [1]. The listed end time for the event is 2026-10-31T16:00:00.000Z [1]. Resolution relies on the Mathematics column of the LiveBench leaderboard, with the latest available LiveBench release selected and the category set to Mathematics [1]. Models are ranked by their displayed score. If two or more models have exactly the same score, the model with the lower listed cost per successful task ranks ahead. If a tie remains, alphabetical order of company names in the market group is the final tiebreaker [1]. The winning contract is the company that occupies first place under this ranking [1]. The rules also cover a missing data source. If the LiveBench leaderboard is unavailable at check time, the market stays open until the leaderboard returns and resolves on the first check after it becomes available. If the source becomes permanently unavailable, the market resolves to "Other" [1]. The provider status is listed as active [1]. The market data in this record is a partial sample. The saved provider event contains 21 markets, and 12 are included here [1]. The included markets were selected by finite Yes price in descending order, using the first reported outcome for nonbinary contracts, and then by volume. Missing or invalid prices rank last [1]. Each included market asks whether one named company will hold first place, so each contract is a separate Yes or No question. Within this sample, the Anthropic contract has the highest Yes snapshot, followed by the OpenAI and Google contracts [1]. The sample does not show the full field, so no conclusion can be drawn about companies that are not included. One included market lists a different end date, 2026-11-01T03:59:00.000Z, than the others [1], so the listed end times should be read market by market. The prices are snapshots of the provider data, not executable quotes or verified probabilities. They were observed at 2026-10-24T12:00:05.917Z [1]. They describe that moment only and are not live values. Because the contract closes after the leaderboard check, the outcome will depend on the scores shown at that check, not on any price shown here.
