Singapore May 10 Peak Temperature: Market Locks In 33°C

The market has already decided. With less than 12 hours before the 2026-05-10 12:00:00 resolution, the 33°C outcome for Singapore’s highest temperature on May 10 sits at 99.2% probability. That is not a market wrestling with uncertainty. That is a market that believes the meteorological data is already telling the story.

Here’s what the measurements are telling us: Singapore in May sits deep in its inter-monsoon transition. Daily maximum temperatures in the 33°C range are climatologically normal for this period. The Meteorological Service Singapore consistently records afternoon highs between 32°C and 34°C during May, with 33°C representing the statistical center of that distribution. The market has priced the most probable physical outcome, not the tails.

How the 33°C Contract Works

This contract resolves YES if the highest recorded temperature in Singapore on May 10, 2026 equals exactly 33°C. The Meteorological Service Singapore provides the official measurement used for resolution. The market closes at 2026-05-10 12:00:00.

• YES (33°C exactly): Priced at $0.99, implied probability 99.2%.
• NO (any other temperature): Priced at $0.01, implied probability 0.8%.

For the NO side to pay out, Singapore’s official maximum temperature on May 10 must land anywhere other than exactly 33°C. That means 32°C, 34°C, or any other value. Singapore’s weather in May is consistent but not perfectly predictable. A passing storm system, cloud cover suppressing afternoon heating, or an unusually humid air mass could push the peak reading one degree lower. A clear, dry afternoon with strong solar radiation could push it to 34°C. Either scenario would flip this contract entirely.

Momentum and Market Signals

The momentum composite here is striking. The 1h change, 24h change, and trend score of 87.41 are all moving together as one signal, pointing sharply toward 33°C. That kind of synchronized movement over a short window typically means new observational data or a forecast update has landed, and traders responded quickly. Given the resolution date, the most likely driver is May 10 morning temperature readings or an updated Meteorological Service Singapore forecast showing conditions consistent with a 33°C peak.

Total market volume sits at $79,414, with $62,775 traded in the last 24 hours. Liquidity is reported at $916,600. That volume figure is below $1 million, which means this market can reprice sharply if a single piece of new data arrives before resolution. One confirmed temperature reading from a Singapore weather station could move this contract to near certainty or collapse it entirely in minutes.

• 1h and 24h change: Both strongly positive, consistent with a late-session confirmation of forecast data pointing toward 33°C.
• Trend score 87.41: Reflects sustained directional conviction over the measurement window, not a single spike.
• Volume at $62,775 (24h): Active for a short-duration science contract, suggesting traders are engaged with real-time meteorological data.
• Liquidity at $916,600: Deep order book relative to volume, meaning the 99.2% price is structurally supported, not a thin-market artifact.
• Open interest at $0: All positions are settled or closed out, consistent with a contract approaching its resolution window.

Lines Analysis: Meteorological Service Singapore and the 33°C Threshold

The case for 33°C rests on climatological base rates. Singapore’s Meteorological Service data shows May afternoon highs cluster around 32°C to 34°C during inter-monsoon periods. The 33°C reading represents the mode of that distribution. If today’s synoptic conditions match the seasonal average, the official maximum lands at 33°C and this contract resolves YES. The market is pricing climatological probability, not an edge case.

What makes the NO side real is measurement precision. Singapore’s official temperature records are taken to single-degree resolution for contract purposes. A maximum of 33.4°C rounds to 33°C. A maximum of 33.6°C could round to 34°C. The difference between YES and NO is not a dramatic weather event. It is a matter of where the afternoon peak lands within a narrow band. Convective activity, sea breeze timing, or afternoon cloud development could all shift that reading by one degree.

• Meteorological Service Singapore morning observation data: a reading trending toward 33°C by mid-morning confirms the YES trajectory.
• Updated numerical weather prediction models for Singapore on May 10: any model shift toward 34°C peak or rain-suppressed 32°C peak would pressure the 99.2% price.
• Convective activity reports: thunderstorm development before peak heating (typically 2 to 4 PM local time) would cap the maximum below 33°C.
• Regional ENSO status: neutral-to-weak La Nina conditions in 2026 tend to keep Singapore temperatures near climatological norms rather than pushing extremes.

The $79,414 market is pricing the most physically plausible outcome. The data favors YES. The single variable that matters before 2026-05-10 12:00:00 is whether Singapore’s afternoon peak on May 10 lands precisely at 33°C or tips one degree in either direction.

LINES VERDICT

Climatologically Confirmed, Precision Pending

The market has done the meteorological math and landed at 99.2% for 33°C. Singapore’s May climate makes this reading the most probable single outcome, and the data doesn’t care about the politics of rounding.

What the market says: 99.2% probability for 33°C as Singapore’s peak temperature on May 10. With resolution at 2026-05-10 12:00:00, the window for repricing is narrow. Thin volume means a single confirmed reading could move this contract sharply in either direction before close.

Key unknown: Whether Singapore’s afternoon maximum on May 10 lands exactly at 33°C or tips to 32°C or 34°C. The Meteorological Service Singapore’s official afternoon observation is the single data point that resolves this contract.

Scientific Context: Singapore’s May Temperature Baseline

Singapore sits about 1.3 degrees north of the equator. The Meteorological Service Singapore records the highest mean daily maximum temperatures of the year during March through May, the inter-monsoon period. Historical records show May daily maximums averaging around 32°C to 33°C at Changi climate station, the primary reference point for official readings. The 33°C threshold in this contract aligns directly with that historical center. In 2025 and 2024, Singapore recorded May daily maximums in the 32°C to 35°C range, with 33°C appearing as one of the most frequent single-day values. The market pricing reflects that base rate accurately. What it cannot reflect is today’s specific synoptic setup, and that is where the 0.8% NO probability lives.

FAQ

• What does 99.2% mean here? The market assigns a 99.2% chance that Singapore’s official highest temperature on May 10 equals exactly 33°C. It does not guarantee the outcome.
• How does the NO contract pay out? The NO position pays if Singapore’s official peak temperature on May 10 is anything other than 33°C, including 32°C or 34°C.
• What data moves this price before resolution? A morning temperature reading from the Meteorological Service Singapore trending above or below 33°C would shift trader conviction and reprice the contract quickly.
• When does this market resolve? Resolution is set for 2026-05-10 12:00:00, based on the Meteorological Service Singapore’s official maximum temperature record for May 10.
• Is the volume reliable? Total volume is $79,414, below $1 million. That means the 99.2% price can shift sharply on a single large trade or new data point before close.
