MetaMask, the widely used crypto wallet built by Consensys, will integrate Polymarket later this year, stepping into the fast-growing world of prediction markets that’s drawing both retail traders and Wall Street investors.
The move will allow MetaMask’s users to access Polymarket directly from within the wallet, letting them buy and sell shares tied to real-world outcomes — from elections and sporting events to company earnings and macroeconomic data.
Gal Eldar, MetaMask’s global product lead, said the collaboration is part of a broader plan to evolve the wallet into what he described as a “gateway to global, democratized finance.”
“Each new feature expands what users can do with their financial assets: trade, earn, invest, speculate, and diversify, all while maintaining full self-custody,” Eldar said.
The feature will roll out globally, excluding the U.S., U.K., France, Singapore, Poland, Thailand, Australia, Belgium, Taiwan, and Ontario, Canada, where regulatory restrictions still limit access to prediction markets.
Prediction markets have become one of the most active corners of decentralized finance, offering a way for traders to bet on political races, market outcomes, and major world events. Activity on these platforms surged during the U.S. presidential election in late 2024, and despite a recent cooldown in trading, the sector continues to attract capital and institutional interest.
On Tuesday, Polymarket secured a $2 billion investment from Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, in a deal valuing the platform at $9 billion. The investment underscores how seriously traditional finance is taking the “truth markets” narrative — where collective speculation can create near real-time forecasts for public events.
According to DefiLlama data, Polymarket and its U.S.-regulated rival Kalshi recorded $1.43 billion and $2.74 billion in trading volume respectively in September, surpassing their combined record from November 2024.
Though activity has cooled from the pre-election frenzy, Eldar said prediction markets remain one of the most potent use cases for blockchain-based systems because they are “fundamentally about truth-seeking.”
“When incentives are aligned and participation is broad, markets become self-correcting systems that push us closer to reality,” he said. “The deeper and more liquid they get, the faster they converge around the truth.”
MetaMask’s Polymarket integration isn’t the wallet’s only move this week. The firm also launched perpetual futures trading through a new partnership with decentralized exchange Hyperliquid, extending its reach into derivatives.
The decentralized perpetuals sector has surged in recent months, racking up around $770 billion in trading volume over the past month, led by Hyperliquid. Still, that figure remains a fraction of volumes on centralized giants like Binance, which continue to dominate thanks to streamlined interfaces and deep liquidity.
By layering in prediction markets and derivatives, MetaMask is moving closer to the full-service model of centralized exchanges — but with a self-custody backbone. The company is betting that users want the convenience of trading across multiple asset classes without surrendering control of their keys.
The twin launches — Polymarket and Hyperliquid — suggest a clear strategy: bring the energy of on-chain speculation into MetaMask’s ecosystem, combining DeFi flexibility with the polish of traditional finance.
As ICE’s backing of Polymarket shows, the boundaries between crypto’s experimental markets and Wall Street’s data-driven speculation are thinning fast. MetaMask, long known as the front door to Web3, now seems intent on turning that door into a trading floor.
