Highest temperature in Chengdu on August 4?

Platform comparison

Market context

Chengdu’s highest temperature on 4 August is being judged against a late-summer pattern that is normally hot, humid and unsettled, with current forecast sites pointing to a daytime peak around 31–32°C and some risk of patchy rain. Model-style guidance in the market’s orbit has been clustered in the low 30s rather than an extreme heat spike, which helps explain why the crowd is not pricing a very high reading. [1][2][3]

That backdrop matters because Chengdu’s August climatology is already warm enough to make the upper 20s and low 30s the base case, but rainfall and cloud cover often cap the ceiling rather than the floor. Travel and weather references put typical August highs near 30–32°C, with 4 August itself historically landing around 32.1°C in one long-run summary, so outcomes in the low-to-mid 30s are the most natural benchmark for reading this contract. [3][5][7]

The main catalyst to watch is whether afternoon heating is interrupted by showers or thunderstorm cover, since even small timing shifts can decide whether the day tops out at 31°C, 33°C or higher. Traders should therefore focus on the day-ahead forecast updates and any intraday revision from the resolution source, rather than broader monthly averages; the market is leaning on the latest short-range temperature outlook rather than on seasonal heat alone.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events.

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.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

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.
