Highest temperature in Manila on June 30?

Platform comparison

Market context

The real-world event is the daily maximum temperature recorded at Ninoy Aquino International Airport on 30 June 2026, with long-term averages for Manila in June consistently hitting 32°C amid very high heat and humidity[3]. Historical data shows daytime peaks regularly reaching 32°C, while short-range PAGASA guidance for this period forecasts a range of 25–33°C, making outcomes between 29–31°C the most statistically probable[1]. The current crowd-implied probability of 0% for any specific high-temperature range appears misaligned with these established climatological patterns, as even the cooler end of the forecast band (25°C) remains well above the 0% threshold implied by the market[1].

Traders should monitor the Low Pressure Area (LPA) forecast for Southern Luzon and Visayas, which is expected to bring heavy to intense rainfall and could suppress temperatures below the typical June maximum[7]. The primary catalyst the market leans on is this weather system’s potential to disrupt the usual heatwave, though UN climate reports indicate global temperatures are likely to remain at record levels through 2030, increasing the baseline risk of extreme heat[4]. Watch for updates from PAGASA and local weather bulletins on the LPA’s movement, as a shift toward the coast could trigger the cooling effect that would invalidate the 31°C frontrunner currently favoured by 37% of traders[1]. Recent forecasts suggest Metro Manila temperatures may reach up to 34°C until the weekend, reinforcing the likelihood of high readings unless the LPA intervenes decisively[8].

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
