The cryptocurrency wallet Phantom has announced a partnership with the platform Kalshi, integrating event outcome trading into its app interface.

John Wang, Kalshi’s recently appointed head of crypto, touted the tie-up as the company’s “biggest crypto announcement yet.”

“We would like to have Kalshi’s prediction markets in every large crypto app,” he previously told Forbes. “Crypto has a super power user community, people who live and breathe cutting edge financial technology every single day.”

The integration means Phantom’s 15 million+ global users will be able to buy and sell tokenized versions of wagers on Kalshi’s contracts without leaving the wallet using tokens like SOL or CASH, a Solana stablecoin Phantom launched in September. 

Earlier this month, Kalshi moved its markets onto the Solana blockchain and partnered with decentralized finance platforms DFlow and Jupiter, which help route Kalshi’s order-book liquidity onto blockchain infrastructure. Although Phantom also supports Ethereum, Polygon and a crop of other blockchains, Kalshi will not be offering tokenized positions elsewhere yet.
