Pronóstico: Highest temperature in Taipei on August 1?

Platform comparison

Market context

Polymarket is currently pricing the **36°C** band as the leading outcome for Taipei’s August 1 high, with the market implying that a hot but not extreme afternoon is the base case for this USDC-settled contract on Polygon. The event resolves off the highest temperature recorded at Taipei Songshan Airport Station on the day, so traders are really betting on the station reading that appears in Wunderground’s daily history, not on headline city forecasts. The current zero per cent YES reading in the prompt does not match the live contract view shown by Polymarket, which places 36°C ahead of 37°C.

That pricing sits in line with what Taipei normally does in August. AccuWeather’s August outlook for Taipei City puts daily highs mostly between **86°F and 92°F** (about **30–33°C**) with overnight lows in the high 20s Celsius, while travel climate guides describe August as hot, humid and sometimes stormy, with typical highs around **33–36°C**. The longer-run frame matters because one sharp late-morning surge, rather than the full-day average, is what decides the conditional tokens in this market.

What traders should watch is any change in the local weather setup before the settlement cut-off, especially afternoon convection, monsoon rainbands or a typhoon track that could cap the day’s maximum. Polymarket’s own contract text says revisions to temperatures inside the market window count until the first datapoint for the following day is published, so late updates to Wunderground’s history can still move the resolution line. On a hands-on basis, that means monitoring the station feed, not just city forecasts, because the final payout is binary: correct range tokens redeem at **$1** on Polygon, and everything else expires worthless.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
