MetaMask, the most widely used Ethereum wallet, is expanding into the prediction market sector through a new integration with Polymarket. The partnership allows users to trade on the outcomes of real-world events directly from their wallets, streamlining access to the growing platform.

A key feature of the integration is “one-tap funding,” which enables users to deposit funds using any token from any Ethereum Virtual Machine (EVM) compatible blockchain. This move significantly lowers the barrier to entry and positions MetaMask as a gateway not just for decentralized applications but also for event speculation. This expansion follows other strategic initiatives, including the recent launch of multichain accounts supporting networks like Solana and preparations for a native MASK token.

Prediction Market Sector Heats Up with Record Activity

The collaboration comes as Polymarket experiences a surge in popularity, partly driven by heightened interest surrounding the 2024 U.S. election cycle. The company is reportedly exploring a valuation of up to $15 billion after securing a strategic investment from Intercontinental Exchange, the parent company of the New York Stock Exchange. However, Polymarket is also reportedly recruiting for an internal market-making team to trade against its own customers, a controversial practice that has drawn legal challenges for rival platforms.

The broader prediction market industry has seen explosive growth, crossing $13 billion in cumulative trading volume. This has attracted major players from finance and tech, including Coinbase and Fanatics, who have recently launched or expanded their own event-trading platforms.

The competitive landscape is intensifying. Opinion, a platform backed by YZi Labs—the venture firm of Binance co-founder Changpeng Zhao—recorded nearly $1.5 billion in weekly volume within its first month. Meanwhile, competitor Kalshi recently closed a $1 billion funding round and secured a major media partnership with CNN, becoming the network’s official prediction markets partner.
