MetaMask integrates Polymarket prediction markets into mobile wallet

Published: 2025-12-05 04:02:47 |

MetaMask has launched “MetaMask Prediction Markets,” a native Polymarket integration in its mobile app that lets users trade on real-world event outcomes directly inside the wallet. The feature, announced Dec. 4, adds a dedicated predictions tab where users can fund positions with any EVM-compatible token in one tap, see odds update in real time, and settle winning bets in under five seconds. Existing Polymarket balances automatically sync. Each trade earns MetaMask Rewards points and contributes to future MASK token incentives. MetaMask charges a flat 4% fee per transaction split with Polymarket, positioning the fee as a predictable alternative to Polymarket’s zero-fee trading. The integration makes MetaMask the first major self-custodial wallet to embed prediction markets natively, exposing Polymarket’s markets—sports, politics, crypto and cultural events—to MetaMask’s 140M+ wallets. The move follows recent product expansions including perpetual futures via Hyperliquid and rewards upgrades, and arrives as Polymarket gains mainstream visibility (odds appearing in Google Search/Finance). Primary keywords: MetaMask, Polymarket, prediction markets, mobile app, MASK. Secondary/semantic keywords: on-chain predictions, EVM tokens, self-custody, rewards points, in-app trading.

Bullish

Embedding Polymarket into MetaMask’s mobile wallet increases on-chain activity and lowers friction for retail participation in prediction markets. For traders, this means faster access to new on-chain flows, more on-chain liquidity in event markets, and additional use cases that can pull capital into EVM token trading and cross-chain transfers. The 4% fee may deter some high-frequency scalpers but provides predictable revenue for MetaMask and Polymarket that could fund growth and marketing, attracting new users. Historically, product integrations that simplify access (e.g., wallets adding swap or staking features) tend to be bullish for on-chain volume and native token utility over time. Short-term impact: modest positive for trading volumes in Polymarket markets and increased activity in EVM token transfers and swaps within MetaMask. Long-term impact: positive for ecosystem adoption, potential tailwinds for MASK token utility/allocations and for Polymarket liquidity as mainstream users adopt wallet-native event trading. Risks include regulatory scrutiny of prediction markets and the relatively high fee slowing uptake versus zero-fee alternatives, which could cap immediate upside.
