Highest temperature in Manila on July 1?

Platform comparison

Market context

The real-world event hinges on whether Manila’s Ninoy Aquino International Airport records a daytime high above 34°C on 1 July 2026, despite the crowd-implied probability of 0% for that outcome. Historical July averages place daytime maxima at 31°C with very high humidity and frequent rainfall, as the wet season dominates from June to October, typically capping highs below 33°C unless cloud cover breaks abruptly [2][4]. Short-range forecasts suggest limited diurnal heating potential, reinforcing trader consensus around 31–32°C, while modest probabilities for 33–34°C reflect only possible model spread or transient steering flow disruptions [1].

Traders should monitor PAGASA’s daily synoptic updates for shifts in westerly wind intensity or sudden cloud dissipation, which could push temperatures toward 34°C—a contrarian angle given the 0% market pricing [8]. Recent local forecasts indicate mostly cloudy skies with highs near 79–81°F (26–27°C), but any unexpected reduction in rainfall or increased sunshine hours could act as a catalyst for higher readings [7][9]. The value spot lies in betting against the 0% implied probability if steering flow anomalies or short-term model errors materialise, as Hong Kong’s July outlook similarly shows uncertainty between seasonal warmth and synoptic influences [3].

Methodology

We track Highest temperature in Manila on July 1? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
