Polymarket Adds Five-Minute Crypto Contracts to US App

Polymarket US is a prediction-market app that now offers very short-duration crypto contracts tied to major tokens. Five-minute formats compress the usual trading window and fit a style of market that resolves quickly instead of over a longer session. The use of CF Benchmarks shows the contracts rely on an external reference price rather than an exchange-specific quote.

For traders, the change means they can express a view on BTC, ETH, SOL, or XRP over a narrow time slice rather than a broader move. The setup also makes the settlement rules more specific: ties go to Up, and taker fees are handled separately from the spread. That kind of structure matters for anyone building around prediction markets because the contract design shapes how orders are entered and how outcomes are resolved.

Short-duration crypto contracts sit at the edge between market participation and rapid-fire speculation. A five-minute format narrows the distance between price movement, contract creation, and settlement, which raises questions about how much these products resemble trading tools versus wagering products. For Polymarket, the model also shows how prediction markets are being adapted to crypto-specific references instead of only election or event contracts.
