Highest temperature in Singapore on July 8?

Platform comparison

Market context

The real-world event is the peak daily temperature recorded at Singapore Changi Airport on 8 July 2026, with current crowd-implied probability at 0% for any outcome exceeding the market’s baseline. Historical data shows Singapore’s July highs typically cluster between 30°C and 32°C, with 31°C being the most frequent maximum over the past decade[7]. Recent Polymarket activity confirms this pattern, assigning 75% probability to 31°C and 21% to 32°C, while 30°C holds 27.5% implied chance[1]. This aligns with BBC Weather’s current forecast for 8 July, which predicts a high of 31°C amid thundery showers and southerly winds[3].

Traders should monitor real-time updates from Wunderground, the official resolution source, and watch for sudden shifts in cloud cover or rainfall intensity that could suppress peak temperatures below 30°C[1]. While no political catalysts directly influence weather, unexpected declarations on urban heat mitigation or infrastructure expansions in Singapore could indirectly alter local microclimates over time. For immediate context, AccuWeather’s 10-day forecast notes morning rain and a high of 88°F (31.1°C) for 8 July, reinforcing the 31°C consensus[5]. The market is leaning on Wunderground’s temperature record as the primary catalyst, with no scheduled debates or campaign-finance disclosures affecting the outcome.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Highest temperature in Singapore on July 8? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

FAQ

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.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

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.
