Highest temperature in Los Angeles on July 26?

Platform comparison

Market context

The real-world event is the hottest reading at Los Angeles International Airport on 26 July, which will be resolved against the airport’s daily history record rather than a citywide estimate. The market is currently split between the **80-81°F** and **74-75°F** bands, with the 80-81°F outcome fractionally ahead at 50% and 74-75°F close behind at 49%.[1]

That spread is typical of a temperature market sitting near a threshold, where one degree of overnight or midday warming can flip the winning band. In weather terms, the key comparison is not whether Los Angeles is broadly warm, but whether the day at KLAX clears the upper 70s and reaches the low 80s, which is the kind of boundary that historically creates tight, binary pricing in these contracts. The current **0% YES** crowd-implied read therefore looks more like a placeholder than a strong weather signal, and the market is effectively leaning on the odds of a single high-temperature print rather than on a broad trend.[1]

For traders, the important catalyst is the official daily high at the airport station, which depends on the exact late-morning through afternoon temperature path at KLAX and can be pushed around by coastal marine influence, inland heat spilling to the coast, or any late-day cooling. There are no political-style debate dates or declarations here, so the practical watchpoint is the forecast cycle and any last-minute update from weather services before the settlement window closes, with the resolution itself tied to Wunderground’s station history rather than to broader Los Angeles forecasts.[1]

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 Los Angeles on July 26? 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

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.

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.

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 Election Predictions UK route into the same order book at 0% fees.

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.

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.
