MetaMask joins Trust Wallet in offering self-custody prediction market access, with Polymarket now enabling event-based trading in sports, politics, crypto, and culture directly within the wallet.
Trust Wallet’s Dec. 2 launch of integrated prediction markets has now been followed by MetaMask’s Dec. 4 announcement of Polymarket integration. MetaMask users can trade event outcome contracts—including sports, politics, crypto, and culture—without forfeiting control of their private keys. This further reflects the rapid growth in crypto-based prediction markets, complementing Trust Wallet’s earlier support for Myriad, Polymarket, and Kalshi in enabling decentralized event trading.
