Singapore May 30 High Temp: Market Calls 32°C

The market has already made its call. The 32°C outcome for Singapore’s highest temperature on May 30 sits at 99.6% implied probability, and the price movement getting there tells a clean story: up 60.6% in 24 hours, with a trend score of 87.94. That kind of momentum doesn’t appear without real-world data confirming the direction.

The market question asks: what is the highest temperature in Singapore on May 30? The 32°C outcome trades at $1.00 YES and $0.00 NO, with $62,313 in total volume and $50,348 changing hands in the last 24 hours. The contract resolves at 12:00 UTC on May 30, 2026, meaning resolution is effectively now.

How the 32°C Contract Works

YES pays out if Singapore’s official highest temperature on May 30 reaches 32°C, as measured by the relevant meteorological authority. NO would require the day’s peak to land outside that reading. Every other outcome — 33°C, 34°C or higher, or anything at 31°C and below — represents a competing contract on Polymarket, not the same trade.

• YES ($1.00): Singapore’s daily high on May 30 resolves at 32°C.
• NO ($0.00): The daily high lands at any other temperature, above or below 32°C.

The path to NO is narrow. Singapore’s Meteorological Service records daily maximum temperatures with precision. For this contract to miss, the official reading would need to land at 31°C or below, or push to 33°C or above. Given where the market has priced competing outcomes, neither scenario is attracting serious capital today.

Momentum and Market Conviction

The composite momentum signal here is unusually sharp. A 32.6% one-hour move combined with a 60.6% 24-hour jump and a trend score of 87.94 points to observed temperature data — not speculation — driving the price. Traders aren’t guessing at what the afternoon will bring. They’re pricing what the instruments are already showing.

Total volume of $62,313 is modest by prediction market standards. The $50,348 in 24-hour volume represents the bulk of total lifetime activity, which confirms this is a fast-moving intraday settlement, not a long-running market. Liquidity at $140,093 is healthy relative to volume, meaning the order book can absorb movement without distortion. That said, thin absolute volume means a single large trade could still shift the displayed price.

• The 1h and 24h momentum composite signals real-time weather confirmation, not anticipatory positioning.
• $50,348 of the $62,313 in total volume moved in the last 24 hours, reflecting late-stage convergence on a known outcome.
• Liquidity ($140,093) exceeds volume, a sign the book was set up to handle resolution cleanly.
• Open interest reads $0, consistent with a contract approaching or at resolution with positions already closed or matched.
• Competing outcomes (33°C, 31°C, etc.) show near-zero activity, confirming market consensus has concentrated on 32°C.

Lines Analysis: What the Data Supports

Singapore’s tropical climate in late May produces consistent daily highs in the 31°C to 34°C range. The Meteorological Service Singapore publishes real-time and daily maximum readings, and the market’s price trajectory strongly suggests those readings have landed at or near 32°C for May 30. Here’s what the measurements are telling us: the convergence to $1.00 is not a bet on a future outcome. It’s a market reflecting an observed fact.

The data doesn’t care about the politics, and in this case, there’s no politics to care about. This is a straightforward temperature measurement market. The scenario where this contract misses requires either a data revision or a late-day reading that shifts the official daily maximum. Singapore’s meteorological records are stable and rarely revised intraday. That makes a NO outcome nearly theoretical at this point.

• Meteorological Service Singapore posts daily maximum temperature data that serves as the resolution basis for this contract.
• A reading above 33°C or below 31°C would reprice the contract, but competing outcome contracts show no capital moving in either direction.
• The $0 open interest figure suggests most positions have already settled or matched, consistent with resolution imminent.
• Any official data revision before 12:00 UTC resolution would be the only remaining path to a price shift.
• Volume concentration in the final 24 hours confirms informed traders acted on observed data, not forecast models.

The $62,313 in total volume is modest, but the directional signal is unambiguous. Every meaningful dollar in this market moved toward 32°C in the final day. The market is pricing a confirmed measurement, not uncertainty.

LINES VERDICT

EFFECTIVELY RESOLVED

The price action and momentum composite reflect observed temperature data, not a prediction. At 99.6% implied probability with $1.00 YES and no capital supporting any competing outcome, this contract has functionally settled before its official resolution time.

What the market says: At 99.6% implied probability, the market treats 32°C as Singapore’s confirmed daily high for May 30. With resolution at 12:00 UTC today, volatility risk is essentially zero unless an official data revision emerges in the final hours.

Key unknown: The only remaining variable is whether Meteorological Service Singapore issues any revision to the daily maximum reading before the 12:00 UTC resolution window closes. That scenario carries near-zero historical precedent.

Scientific Context: Singapore Temperature in Late May

Singapore sits roughly 1.3 degrees north of the equator. Daily maximum temperatures in May typically range from 31°C to 34°C, with 32°C and 33°C being the most common outcomes in recent years. The urban heat island effect in central Singapore can push readings slightly higher than surrounding areas. The Meteorological Service Singapore’s official daily maximum is the authoritative figure for markets like this one.

Before this contract’s end date arrives, no additional data release will reprice it. The measurement has been taken. The market has absorbed it. What remains is the formality of official resolution.

What is the probability number in this market?

The 99.6% implied probability means traders collectively price a 99.6% chance Singapore’s official daily high on May 30 lands at exactly 32°C, based on observed meteorological data available before resolution.

What does NO pay out on?

The NO outcome at $0.00 pays nothing. For NO to have value, the official daily maximum would need to resolve at any temperature other than 32°C, including 31°C, 33°C, or any other listed outcome.

What data event would move this price?

Only an official revision to the Meteorological Service Singapore’s daily maximum temperature reading for May 30 could reprice this contract. No forecast model or pending data release is relevant at this stage.

When does this contract resolve?

The contract resolves at 12:00 UTC on May 30, 2026. At the time of this analysis, resolution is imminent, and the price reflects finalized or near-finalized temperature data.

Is the volume reliable enough to trust the price?

Total volume of $62,313 is thin by prediction market standards. However, liquidity at $140,093 exceeds volume, and the directional consensus is absolute. Thin volume means a single trade could move the displayed price, but no capital is challenging the 32°C outcome.
