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":"[\"1\", \"0\"]","volume":"22266.274154999996","active":true,"closed":true,"marketMakerAddress":"","createdAt":"2026-10-01T12:00:51.225454Z","updatedAt":"2026-10-03T13:53:08.757848Z","closedTime":"2026-10-02 22:29:56+00","new":false,"featured":false,"submitted_by":"0xAC9930b2AE455a671b62dE86876A7e8587825294","archived":false,"resolvedBy":"0x65070BE91477460D8A7AeEb94ef92fe056C2f2A7","restricted":true,"questionID":"0x3c9284b8559a3613769e77b8293e3e0a5e37e4b4cfaff1f49aa175a468d4d4ae","umaEndDate":"2026-10-02T22:29:56Z","enableOrderBook":true,"orderPriceMinTickSize":0.001,"orderMinSize":5,"umaResolutionStatus":"resolved","volumeNum":22266.274154999996,"endDateIso":"2026-10-02","startDateIso":"2026-10-01","hasReviewedDates":true,"volume24hr":17000,"volume1wk":22266.274155,"volume1mo":22266.274155,"volume1yr":22266.274155,"gameStartTime":"2026-10-01 21:00:00+00","clobTokenIds":"[\"31248693527926117708547542517997620301156514110424007370937312117399775541889\", \"47558559438539105416867251147036885665217593297208710779209184479088540690700\"]","comboStatus":"disabled","umaBond":"250","umaReward":"0.6","volume24hrClob":17000,"volume1wkClob":22266.274155,"volume1moClob":22266.274155,"volume1yrClob":22266.274155,"volumeClob":22266.274154999996,"makerBaseFee":1000,"takerBaseFee":1000,"acceptingOrders":false,"negRisk":false,"ready":false,"funded":false,"acceptingOrdersTimestamp":"2026-10-01T12:00:58Z","cyom":false,"approved":true,"rewardsMinSize":100,"rewardsMaxSpread":2.5,"spread":0.001,"automaticallyResolved":true,"oneDayPriceChange":0.5245,"lastTradePrice":0.999,"bestBid":0.999,"bestAsk":1,"automaticallyActive":true,"clearBookOnStart":false,"manualActivation":false,"negRiskOther":false,"umaResolutionStatuses":"[\"proposed\", \"proposed\"]","pendingDeployment":false,"deploying":false,"deployingTimestamp":"2026-10-01T12:00:51.523304Z","rfqEnabled":false,"eventStartTime":"2026-10-02T13:30:00Z","holdingRewardsEnabled":false,"feesEnabled":true,"feeType":"finance_prices_fees","feeSchedule":{"exponent":1,"rate":0.04,"takerOnly":true,"rebateRate":0.25},"version":"v1"}
