Highest temperature in Manila on July 1?

Platform comparison

Market context

The underlying event is the highest temperature recorded at Ninoy Aquino International Airport on 1 July 2026, measured in degrees Celsius. Historical data shows Manila’s July daytime highs typically reach 31°C, with the wet season (June to October) averaging 26°C to 31°C due to heavy rainfall and high humidity [1][2]. The hottest months in Manila are March and April, not July, with April often exceeding 34°C in recent years [2][6]. Given that July is firmly within the wet season and temperatures rarely breach 32°C, the crowd-implied 0% probability for a “YES” outcome (likely indicating an extreme threshold) aligns with climatic norms rather than anomaly.

Traders should monitor PAGASA’s daily temperature bulletins and Wunderground’s real-time station data for 1 July, as sudden shifts in cloud cover or wind patterns could marginally alter peak readings [2][6]. While no major weather announcements are scheduled for that date, the broader macro context includes BTC/ETH funding rates and whale flows, which may influence liquidity on USDC-settled prediction contracts if volatility spikes [6]. Recent PAGASA data confirms Laoag and Catbalogan hit 34.0°C by 30 June, but Manila remains cooler, reinforcing the low likelihood of extreme heat [6]. Exchange spot prices and funding rates on major crypto venues will be critical for assessing contract demand as the settlement window closes on 1 July 2026 at 12:00 UTC.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

How volatile are crypto prediction markets?

Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.

Which crypto markets exist on Polymarket?

Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.

Are crypto prediction markets taxable in the US?

In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
