Note that all figures will be rounded to the nearest cent using standard rounding.\n\nIf SPX does not trade at all during the regular session, the market will resolve 50-50.\n\nIf either of the relevant days are shortened (for example, due to a market holiday schedule), the official open/close price published by S&P 500 Index for that shortened session will still be used for resolution.\n\nIf the previous trading day has no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price.\n\nThe resolution source for this market is the Wall Street Journal, specifically the Open/Close values published by the WSJ under \"Historical Prices\".\n\nUS: https://www.wsj.com/market-data/stocks\nEMEA: https://www.wsj.com/market-data/stocks/emea\nASIA: https://www.wsj.com/market-data/stocks/asia","outcomes":"[\"Up\", \"Down\"]","outcomePrices":"[\"0\", \"1\"]","volume":"11900.820047000003","active":true,"closed":true,"marketMakerAddress":"","createdAt":"2026-10-06T12:00:51.255543Z","updatedAt":"2026-10-08T07:36:57.628529Z","closedTime":"2026-10-07 22:29:26+00","new":false,"featured":false,"submitted_by":"0xAC9930b2AE455a671b62dE86876A7e8587825294","archived":false,"resolvedBy":"0x65070BE91477460D8A7AeEb94ef92fe056C2f2A7","restricted":true,"questionID":"0xceae83a42848ecc25856f961ef5e5716d09fed619a0f2b018f8ef207b824de7e","umaEndDate":"2026-10-07T22:29:26Z","enableOrderBook":true,"orderPriceMinTickSize":0.001,"orderMinSize":5,"umaResolutionStatus":"resolved","volumeNum":11900.820047000003,"endDateIso":"2026-10-07","startDateIso":"2026-10-06","hasReviewedDates":true,"volume24hr":9929.075296,"volume1wk":11902.671898999999,"volume1mo":11902.671898999999,"volume1yr":11902.671898999999,"gameStartTime":"2026-10-06 21:00:00+00","clobTokenIds":"[\"72231001709399425398644321186162176912046139024866395255526774623740240630724\", \"32294585449178760945894829032367504169050151019200477611164199201619054872078\"]","comboStatus":"disabled","umaBond":"250","umaReward":"0.6","volume24hrClob":9929.075296,"volume1wkClob":11902.671898999999,"volume1moClob":11902.671898999999,"volume1yrClob":11902.671898999999,"volumeClob":11900.820047000003,"makerBaseFee":1000,"takerBaseFee":1000,"acceptingOrders":false,"negRisk":false,"ready":false,"funded":false,"acceptingOrdersTimestamp":"2026-10-06T12:00:58Z","cyom":false,"approved":true,"rewardsMinSize":20,"rewardsMaxSpread":4.5,"spread":0.001,"automaticallyResolved":true,"oneDayPriceChange":-0.5795,"lastTradePrice":0.005,"bestAsk":0.001,"automaticallyActive":true,"clearBookOnStart":false,"manualActivation":false,"negRiskOther":false,"umaResolutionStatuses":"[\"proposed\", \"proposed\"]","pendingDeployment":false,"deploying":false,"deployingTimestamp":"2026-10-06T12:00:51.522552Z","rfqEnabled":false,"eventStartTime":"2026-10-07T13:30:00Z","holdingRewardsEnabled":false,"feesEnabled":true,"feeType":"finance_prices_fees","feeSchedule":{"exponent":1,"rate":0.04,"takerOnly":true,"rebateRate":0.25},"version":"v1"}
