Market context

Wellington's maximum temperature on 26 May 2026 will be measured at the airport weather station and resolved against historical temperature bands. The settlement window closes at midday on that date, meaning the final reading will capture the day's peak before the market locks.

May sits in Wellington's late autumn period, when daily highs typically range between 12 and 16 degrees Celsius. Historical data from the airport station shows that temperatures exceeding 20 degrees in late May are rare but not unprecedented; the city's maritime climate moderates extremes, though nor'west föhn winds can occasionally push readings higher. The 0% crowd probability suggests traders are pricing in either a very narrow expected range or treating this as a baseline reference market where consensus hasn't yet crystallised around specific temperature bands.

The New Zealand MetService forecast for late May 2026 will be the practical guide for traders assessing likelihood across temperature brackets. Seasonal patterns favour cooler outcomes given the time of year, but individual weather systems—particularly any warm air mass moving south from the tropics—could shift outcomes materially. Traders should monitor MetService's 10-day outlook as the settlement date approaches, particularly any signals of nor'west flow or high-pressure systems that historically correlate with above-average May temperatures in Wellington. The airport station's continuous recording provides objective resolution, eliminating interpretation disputes once the day concludes.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
