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":"[\"0.0005\", \"0.9995\"]","volume":"17450.539871","active":true,"closed":false,"marketMakerAddress":"","createdAt":"2026-10-13T12:00:51.342529Z","updatedAt":"2026-10-14T20:52:52.562909Z","new":false,"featured":false,"submitted_by":"0xAC9930b2AE455a671b62dE86876A7e8587825294","archived":false,"resolvedBy":"0x65070BE91477460D8A7AeEb94ef92fe056C2f2A7","restricted":true,"questionID":"0x45ef29642ed8db8aaf9fe91a2369bbe51145cbe4749f9bcc452e44f95056a905","enableOrderBook":true,"orderPriceMinTickSize":0.001,"orderMinSize":5,"umaResolutionStatus":"proposed","volumeNum":17450.539871,"liquidityNum":9725.92728,"endDateIso":"2026-10-14","startDateIso":"2026-10-13","hasReviewedDates":true,"volume24hr":16936.640454,"volume1wk":17450.539871,"volume1mo":17450.539871,"volume1yr":17450.539871,"gameStartTime":"2026-10-13 21:00:00+00","clobTokenIds":"[\"98346302443584559925860654637914232533932488990211745600797005540009457433821\", \"93018991307865035587486347682485796519885595296969790895383057747253547349539\"]","comboStatus":"disabled","umaBond":"250","umaReward":"0.6","volume24hrClob":16936.640454,"volume1wkClob":17450.539871,"volume1moClob":17450.539871,"volume1yrClob":17450.539871,"volumeClob":17450.539871,"liquidityClob":9725.92728,"makerBaseFee":1000,"takerBaseFee":1000,"acceptingOrders":true,"negRisk":false,"ready":false,"funded":false,"acceptingOrdersTimestamp":"2026-10-13T12:01:00Z","cyom":false,"competitive":0.8003199679231757,"approved":true,"rewardsMinSize":20,"rewardsMaxSpread":4.5,"spread":0.001,"oneDayPriceChange":-0.4945,"lastTradePrice":0.001,"bestAsk":0.001,"automaticallyActive":true,"clearBookOnStart":false,"manualActivation":false,"negRiskOther":false,"umaResolutionStatuses":"[\"proposed\", \"proposed\"]","pendingDeployment":false,"deploying":false,"deployingTimestamp":"2026-10-13T12:00:51.555282Z","rfqEnabled":false,"eventStartTime":"2026-10-14T13:30:00Z","holdingRewardsEnabled":false,"feesEnabled":true,"feeType":"finance_prices_fees","feeSchedule":{"exponent":1,"rate":0.04,"takerOnly":true,"rebateRate":0.25},"version":"v1"}
