High Roller Technologies Inc. (ROLR) stock more than doubled after the online casino operator said it planned to introduce an event-based prediction market in the U.S. in conjunction with Crypto.com.

The Las Vegas-based company said Tuesday it will initially offer its customers Crypto.com Derivatives North America (CDNA) event contracts in the U.S. across finance, sports and entertainment. CDNA is a CFTC-registered exchange and clearinghouse and affiliate of Crypto.com. It didn't say when the planned market would start operating.

The company's share rose as much as 130% and were recently 65% higher at $8.32. Crypto.com’s CRO token gained 3% after the announcement to 7 cents.

Prediction markets have quickly gone from being niche betting platforms to a growing sector of sophisticated trading platforms that aggregate real-world event probabilities. Leading participants include Kalshi, a CFTC-regulated U.S. exchange for event contracts, and Polymarket, one of the largest decentralized markets covering politics, sports and economics. The market is expected to mature into one with trading volume in excess of $1 trillion by 2030, according to High Roller.

Prediction markets are running at an annualized revenue rate above $3 billion, up from about $2 billion in December, and could reach $10 billion by 2030, according to a recent report by U.S. bank Citizens.
