Highest temperature in Paris on August 15?

Platform comparison

Market context

The market concerns the highest temperature recorded at Paris-Le Bourget Airport on 15 August 2026, with settlement based on Weather Underground's Daily Observations table rather than summary figures. The current crowd-implied probability of 1% suggests traders expect temperatures to fall outside a specific range on that date, though the exact threshold is not specified in available documentation.

Paris experiences considerable temperature variation in mid-August, with historical records showing highs typically between 24–28°C, though extremes have reached into the low 30s during heat waves. The 1% probability reflects either an expectation of unusually cool conditions or an unusually high threshold set for resolution. August 2023 saw Paris reach 32°C on the 15th; August 2022 peaked at 29°C on that date. These precedents suggest moderate summer warmth is the norm, making outlier scenarios—whether exceptionally cool or exceptionally hot—relatively unlikely.

Traders should monitor European weather forecasting updates as August 2026 approaches, particularly from Météo-France and the European Centre for Medium-Range Weather Forecasts, which typically issue reliable 10–14 day outlooks roughly two weeks before the settlement date. Broader climate patterns, including Atlantic pressure systems and any developing heat domes across Western Europe, will influence final conditions. The specificity of the resolution source—Weather Underground's Daily Observations table at Le Bourget—means traders must verify data consistency, as discrepancies between observation stations or reporting methods could affect settlement interpretation.

Methodology

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

For political markets the resolution source is decisive. Polymarket defines a concrete source per contract (e.g. AP, Reuters, official electoral commission) and uses the UMA Optimistic Oracle as the on-chain dispute mechanism. With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.

UK Frequently Asked Questions

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.

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.

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.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
