Polymarket US Launches 5-Minute Bitcoin, Ethereum, Solana, and XRP Predictions

Polymarket US has opened 5-minute binary options prediction contracts for Bitcoin, Ethereum, Solana, and XRP. The launch comes after Polymarket successfully rejoined the US market through the CFTC-regulated QCX LLC. Polymarket and Kalshi continue to face state opposition, with full and partial bans in several jurisdictions. Polymarket has officially launched 5-minute crypto price prediction contracts on the Polymarket US App. Shortlisted cryptocurrencies include Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and XRP. The app operates as a binary options market (up and down forecasts), with correct predictions paying out at $1 per contract.
