Phantom said Oct. 28 that eligible U.S. users were being offered 15-minute Bitcoin (BTC) price-direction contracts, extending the wallet’s Kalshi integration to a short-term market.
Each contract follows Bitcoin’s direction over a 15-minute period. Customers select one of two outcomes in Phantom’s Predict area, where a new interval begins every quarter hour. The tab also lists markets on other crypto assets, pro and college sports, economic topics, politics and current events.
Trades run through Kalshi’s account system. The exchange reviews customers, approves trading access and processes orders sent through Phantom. Customers must connect a Kalshi account or create one and complete identity checks before trading.
Access is unavailable in Michigan, Nevada and Washington, and rules vary by market category. The offering builds on Phantom’s earlier rollout of Kalshi event markets for U.S. wallet users.
