Polymarket US has introduced five-minute price-direction contracts for Bitcoin, Ethereum, Solana and XRP, allowing eligible users to trade on whether each cryptocurrency will finish a five-minute interval higher or lower. The launch was announced on October 27, 2026.

Key Takeaways

  • Winning positions pay $1 per contract at settlement; losing positions expire without a payout.
  • The contracts use CF Benchmarks prices, with ties resolved in favor of Up.
  • Taker fees are charged separately from the bid-ask spread.

How the Polymarket US contracts work

Each market offers Up and Down outcomes for a fixed five-minute period rather than requiring a prediction of a specific price target. The Polymarket US crypto listings include five-minute markets for all four assets.

The purchase price determines the potential gain or loss. For example, a winning contract bought for $0.60 would pay $1, producing $0.40 in gross profit before fees. An unsuccessful position would lose its $0.60 purchase cost.

Settlement and trading costs

The US platform uses CF Benchmarks pricing to determine outcomes. A trader’s view of a cryptocurrency’s spot price on an exchange may therefore differ from the outcome determined under the contract’s reference methodology.

Taker fees are separate from the bid-ask spread. Fees, spreads, liquidity and execution can all affect the result of trading contracts with such short settlement windows.

A shorter US trading window

The launch expands Polymarket’s US lineup rather than introducing the format to the company for the first time. Polymarket introduced five-minute Bitcoin markets internationally in February 2026. On October 15, its US platform added 15-minute, hourly and daily markets for Ethereum, Solana and XRP.

Polymarket’s US application operates separately from its international platform through infrastructure regulated by the Commodity Futures Trading Commission. Polymarket has not disclosed initial trading volume or active user figures for the new contracts.
