Polymarket Adds Five-Minute Crypto Contracts to US App

Polymarket US relaunched this year after the CFTC's 2022 settlement had barred US customers from its original offshore platform, and it returned to the regulated market by acquiring QCEX, a CFTC-licensed exchange. Its earlier contracts covered elections and sports outcomes over days or weeks. Five-minute crypto up-or-down bets instead mirror the ultra-short binary contracts Kalshi already runs, pricing them off CF Benchmarks, the Kraken-owned index also used in CME crypto futures.

Users can now wager on five-minute BTC, ETH, SOL and XRP price direction inside a regulated US app rather than turning to offshore derivatives venues. The tie-goes-Up settlement rule changes payout outcomes compared with voiding a tied market, and taker fees charged on top of the spread raise the real cost of trading these contracts repeatedly. Frequent traders and market makers now have to price that spread-plus-fee structure into any high-frequency strategy.

Five-minute binary contracts sit closer to short-dated options than to the forecasting markets prediction platforms were built to be, testing whether CFTC oversight of 'event contracts' fits instruments this tightly tied to raw price moves. Settling every five minutes rewards speed over judgment, which can feed short-term volatility rather than aggregate genuine information, the stated justification for prediction markets. Kalshi has already pushed this boundary, and how far regulators let it stretch will shape the category. (per cryptobriefing.com)

Whether this format stays confined to BTC, ETH, SOL and XRP or expands to more assets and even shorter windows will show how aggressively Polymarket US pushes into derivatives-like territory. Watch trading volume in these five-minute markets and any CFTC response to the tie-settlement and separate taker-fee structure, since either could prompt a rule change or a broader review of how 'prediction' contracts are classified against regulated futures products.
