Manila Temperature Market Locks in Thirty Degrees

Manila’s daily temperature market has effectively closed before the clock runs out. The thirty-degree outcome carries a 97.4% implied probability as of July 11, 2026, a figure the market reached after a sharp two-day run that added roughly fifty-five percentage points of conviction in just forty-eight hours. Here’s what the measurements are telling us: the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) data for Metro Manila consistently shows daily highs clustering in the thirty-to-thirty-two degree Celsius range through July, and today’s market has priced the floor of that band as near-certain.

The market question asks which single temperature bucket captures Manila’s highest reading on July 11. The thirty-degree outcome trades at 0.97 YES and 0.03 NO. Total volume across all outcomes stands at $68,837, with $56,736 of that arriving in the last twenty-four hours alone. The contract resolves at 12:00 UTC on July 11, 2026.

How the Thirty-Degree Contract Works

This is a multi-outcome temperature market. Each bucket represents a discrete Celsius maximum. Thirty degrees resolves YES if Manila’s official highest temperature on July 11 falls exactly at thirty degrees Celsius, and NO if any other bucket captures the actual reading. PAGASA serves as the primary measurement authority for Metro Manila surface temperature records.

• Thirty degrees YES trades at 0.97 (97.4% implied probability).
• Thirty degrees NO trades at 0.03 (2.6% implied probability).

The NO side pays out if Manila’s actual high lands below thirty degrees, above thirty degrees, or in any adjacent bucket including twenty-nine, thirty-one, or thirty-two degrees. PAGASA records a daily maximum that diverges from thirty degrees Celsius roughly whenever monsoon cloud cover suppresses daytime heating or an unusually clear afternoon pushes readings higher. July sits in the southwest monsoon season for Metro Manila, which typically moderates extremes and keeps highs in a tight band, but the band itself is wide enough to include adjacent buckets.

Momentum and Market Signals

The momentum composite here is unusually strong. The one-hour change is flat at zero, but the twenty-four-hour change of plus twenty-nine percent combined with a trend score of 64.07 signals that conviction arrived in a single concentrated burst rather than a gradual drift. The driver is straightforward: real-time or near-real-time temperature observations from Manila on the morning of July 11 entered trader awareness, and the market re-rated sharply from the prior equilibrium near thirty-three cents.

Total volume of $68,837 is modest by prediction market standards, and $56,736 of that arrived in the last twenty-four hours. Liquidity sits at $163,441, which is deep relative to volume and means the current price is not an artifact of a thin order book. That said, total volume below one hundred thousand dollars means a single large position could still move the contract meaningfully if new observational data contradicted the current consensus. The data doesn’t care about the politics, and right now the data is pointing firmly at thirty degrees.

• The momentum composite (flat one-hour, plus twenty-nine percent twenty-four-hour, trend score 64) reflects a single information event, most likely early July 11 temperature readings becoming available.
• Liquidity of $163,441 is healthy relative to volume, reducing the risk of price distortion from thin order books.
• Volume below one hundred thousand dollars means the market is informationally driven but not deeply capitalized, and a weather surprise could still generate sharp repricing before resolution.
• The southwest monsoon typically suppresses Manila highs, supporting the thirty-degree bucket over hotter alternatives like thirty-three or thirty-four degrees.
• The twenty-four-hour volume surge suggests traders responded to observed morning temperatures rather than forecasts alone.

Lines Analysis: Manila’s July Temperature Pattern

PAGASA historical records show Metro Manila in July averaging daily highs in the thirty-to-thirty-two degree range, with the southwest monsoon frequently capping extremes. The thirty-degree bucket sits at the lower end of that range, which makes it a plausible landing zone when cloud cover from the habagat suppresses afternoon heating. The sharp price movement over July 10 and into July 11 is consistent with traders observing morning readings and extrapolating to the daily maximum with high confidence.

The adjacent thirty-one-degree bucket represents the clearest competing outcome. A modest shift in cloud cover, an afternoon clearing event, or PAGASA measuring a slightly warmer microclimate station could push the official daily maximum one degree higher. The specific condition that breaks the thirty-degree contract is not dramatic: a single degree of additional heating, well within the natural variability of a Manila July day, would be enough. That is why the NO price, while small, is not zero.

• PAGASA’s morning temperature readings before resolution at noon UTC are the most direct signal to monitor.
• Southwest monsoon cloud cover reports from the Philippine weather bureau would indicate whether afternoon suppression is holding.
• Any PAGASA advisory about a temporary break in monsoon flow would be a bullish signal for the thirty-one or thirty-two degree buckets.
• International numerical weather prediction models (ECMWF, GFS) showing Manila maximum forecasts above thirty degrees would pressure the current pricing.
• The noon UTC resolution means only the first half of Manila’s local day (roughly 8 PM local time) matters, which typically captures the daily maximum in July.

Total volume of $68,837 is thin, but the liquidity depth at $163,441 suggests the current price reflects genuine trader conviction rather than a single distorting position. The data favors the thirty-degree outcome. The market is pricing a near-certainty, not uncertainty, and the measurement record supports that call for a monsoon-season Manila day.

LINES VERDICT

THIRTY DEGREES CONFIRMED

The market has already done its work. PAGASA’s July temperature record and the southwest monsoon pattern both support a thirty-degree daily maximum, and the morning observation data that drove today’s price surge has effectively closed the debate.

What the market says: At 97.4% implied probability, traders have priced this contract as resolved in all but name. Volatility risk is minimal but nonzero: the noon UTC resolution window and thin total volume mean a late observational surprise could still move the contract before final settlement.

Key unknown: The single most important remaining data point is PAGASA’s official daily maximum reading at or before the noon UTC resolution cutoff. If that number comes in at thirty-one degrees or higher, the contract reprices instantly.
