The market has already priced this as settled, with implied probability sitting at 99.9%. That kind of conviction doesn’t arrive randomly. It arrives when real-time weather data, historical Singapore climate patterns, and trader positioning all point in the same direction simultaneously. The market question asks: what will the highest temperature in Singapore be on June 24? The 31°C outcome carries a YES price of $1.00 against a NO price of $0.00. The market resolves at 12:00 UTC on June 24, 2026, with total volume reaching $119,405. How the Singapore Temperature Contract Works This contract resolves YES if Singapore’s official highest temperature on June 24, 2026, registers at exactly 31°C. The contract resolves NO if any other outcome on the listed scale (25°C or below through 35°C or higher) proves correct. Singapore’s Meteorological Service provides official daily maximum temperature readings. The market closes at noon UTC on June 24. YES (31°C): priced at $1.00, implying 99.9% probability that 31°C is confirmed as the day’s high.NO (any other temperature): priced at $0.00, implying the market sees essentially zero chance of a different outcome. A NO payout requires Singapore’s official maximum temperature to land anywhere other than 31°C on June 24. Singapore’s Meteorological Service would need to record 30°C or lower, or 32°C or higher, to invalidate the dominant position. Given that the 31°C band sits near Singapore’s average June daily maximum, the meteorological threshold is plausible year-round. But the 24-hour price jump of 60% tells you this isn’t abstract probability anymore. The data already exists or is extremely close to confirmed. Sponsored Partner Momentum and Market Conviction The momentum composite here is extraordinary. The 24-hour price change of +60.0% combined with a trend score of 65.14 and zero 1-hour movement signals a market that exploded upward on a confirmed data signal and then locked in. That pattern is typical when real-time or near-final weather readings become available to traders. The market moved, absorbed the information, and stopped moving because nothing is left to price. Total volume stands at $119,405, with $104,384 of that arriving in the last 24 hours. Liquidity sits at $94,634. For a single-day weather contract on a specific city, this is meaningful activity. The 24-hour volume surge confirms the 60% price jump was conviction-driven, not a thin-order artifact. Here’s what the measurements are telling us: traders saw something specific and moved heavily. The 24-hour volume of $104,384 represents roughly 87% of total contract volume, indicating the market formed its view almost entirely within the final trading window.The 1-hour price change of +0.0% confirms the market reached equilibrium and stopped moving, consistent with near-certainty pricing on a resolving contract.The trend score of 65.14 sits in strongly bullish territory, aligning with the directional lean of all recent price action.Liquidity of $94,634 means the order book is deep enough that this price reflects genuine market consensus, not a thin-market illusion.The 24-hour price move of +60.0% traces directly to real-time weather data becoming available for Singapore on June 24. Lines Analysis: What the Singapore Data Shows Singapore’s climate in June is well-characterized. The city-state sits just one degree north of the equator, and June daily maximum temperatures typically range between 30°C and 33°C. A reading of 31°C falls squarely within the statistical core of expected June highs. The Meteorological Service of Singapore publishes daily extremes, and the market’s near-instant convergence to 99.9% strongly suggests that official or near-official temperature readings for June 24 are already accessible to traders. The data doesn’t care about the politics, and in this case, there is no politics. There is only the thermometer. The path to a NO outcome exists on paper. Singapore could record an unusually cool June day below 30°C or an unusually hot day above 32°C. Neither would be unprecedented in absolute terms, but both would be outliers relative to June climatology. The Meteorological Service records show that Singapore’s June daily maximums fall below 30°C or above 33°C in only a small fraction of historical observations. The 60% price surge and the convergence to $1.00 suggest traders have already seen the answer. The Meteorological Service of Singapore publishing final June 24 temperature data would confirm resolution and eliminate any residual uncertainty.Any late-breaking weather station revision showing a reading outside the 31°C band would be the only remaining catalyst for price movement.Singapore’s June climate baseline strongly supports mid-range daily highs between 30°C and 32°C, making 31°C the statistically central outcome.The contract’s noon UTC resolution window means afternoon convective activity, a common Singapore phenomenon, may not factor into the official daily maximum.Related market pricing (74% for Singapore and Southeast Asia temperatures in annual rankings) is consistent with the region operating near its historical high baseline in 2026. Total volume of $119,405 on a single-day temperature contract shows real trader interest in granular weather outcomes. The data favors the YES side overwhelmingly, and the market has reflected that since the 60% move locked in the price. The market is pricing certainty, not uncertainty. LINES VERDICT MARKET CONCLUDED The 31°C outcome has captured essentially all market probability. The 60% price surge on confirmed-day volume tells you this market resolved itself before the official close. What the market says: At 99.9% implied probability, the market treats a 31°C Singapore high on June 24 as a done fact. With the resolution window closing at noon UTC on June 24, the remaining volatility risk is near zero. Key unknown: The single remaining question is whether the Meteorological Service of Singapore’s official final reading confirms exactly 31°C or reveals a rounding or station adjustment that shifts the outcome to 30°C or 32°C. Frequently Asked QuestionsWhat does 99.9% probability mean for the Singapore temperature contract?It means traders collectively assign less than a 0.1% chance to any outcome other than 31°C. At $1.00 YES price, the market treats this as a confirmed result.How does the NO side of this contract pay out?NO pays if Singapore's official daily maximum on June 24 lands on any temperature other than 31°C, including 30°C, 32°C, or any other listed outcome.What data or event caused the 60% price jump in 24 hours?Real-time or near-final weather readings for Singapore on June 24 became available to traders, driving rapid convergence to near-certainty pricing for the 31°C outcome.When does this market resolve?The contract resolves at 12:00 UTC on June 24, 2026, based on the Meteorological Service of Singapore's official daily maximum temperature reading.Is the $119,405 volume enough to trust this market's price?Volume is moderate, but $94,634 in liquidity and $104,384 arriving in 24 hours indicate genuine conviction. Thin-market distortions are unlikely at this depth.How is the Smart Money Index calculated?We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market.

Official Confirmation Locks Resolution The Meteorological Service of Singapore publishes its final June 24 daily maximum at exactly 31°C, confirming what the market already priced. All YES holders collect at $1.00. No further price movement occurs because the contract resolves as traded. This is the overwhelmingly dominant scenario at current probability levels. Station Adjustment Shifts the Reading A weather station revision or data quality check by the Meteorological Service of Singapore moves the official daily maximum to 30°C or 32°C before the noon UTC resolution window closes. This is the primary remaining risk, however small. Such revisions are rare but not impossible in near-real-time meteorological reporting. Adjacent Temperature Captures Resolution If Singapore's official reading lands at 30°C or 32°C, those outcome contracts would capture resolution value. Both sit adjacent to the dominant band and would represent a rounding boundary call by the Meteorological Service. Traders holding those positions would benefit from any last-hour convective suppression or afternoon temperature spike that pushes the final reading off the 31°C mark. Unexpected Convective Event Near Noon UTC A sudden late-morning squall or Sumatra squall line, a known Singapore weather phenomenon, could depress afternoon temperatures before the noon UTC resolution cutoff. If peak heating occurs after the resolution window, the official daily maximum within the trading period could fall below 31°C. Singapore's equatorial weather makes afternoon convection common, but pre-noon events are less frequent. Key macro factor: Singapore's position in a region experiencing above-average sea surface temperatures in 2026 supports persistent daily maximums at or near the 31°C range throughout June.
