Boston Temperature Bet Takes Center Stage on Coinbase Prediction Market

A new prediction market on Coinbase allows users to trade contracts on future events. The first event is the lowest temperature in Boston on June 27, 2026. Users can buy 'Yes' or 'No' contracts with a fee applied for operating the market and broker fees.

The price of each contract reflects the market's odds, such as $0.65 meaning a 65% chance. If the event happens, users who bought 'Yes' contracts earn $1 per contract minus what they paid (minus fees). If it doesn't happen, those who bought 'No' contracts earn $1 per contract.

Coinbase Financial Markets offers regulated prediction markets on outcomes in crypto, economics, politics, sports, entertainment, technology, science, and more. New markets are added regularly with clear rules and settlement policies based on the result.
