MetaMask adds Polymarket prediction markets to mobile app

MetaMask is expanding its mobile wallet into a wider trading hub with a new integration built around Polymarket.

MetaMask has rolled out “MetaMask Prediction Markets,” a feature that lets users trade the outcomes of real-world events directly in the mobile app.

The update, announced on Dec.4, introduces a dedicated predictions tab built on Polymarket, turning the wallet into a single entry point for placing on-chain bets without switching between platforms.

A faster path into prediction markets

The new feature focuses on speed, simplicity, and mobile access. Users can fund positions with any EVM-compatible token in one tap, including assets from Ethereum (ETH) and layer-2 networks. There is no separate onboarding, and bets settle in under five seconds, which suits live events such as sports games or political debates.

If a user already has funds tied to Polymarket, the app automatically syncs them. Each trade earns MetaMask Rewards points, which connect to the wallet’s wider incentive program that launched earlier this year.

Predictions now join swaps, referrals, and perpetual futures as activities that feed into future perks. Points also line up with the expected MASK token allocation once MetaMask finalizes details.

A 4% flat fee applies to each transaction, split between MetaMask and Polymarket. While higher than Polymarket’s zero-fee trading, MetaMask is positioning the fixed rate as a predictable structure similar to mainstream betting apps.

Polymarket becomes a native experience

MetaMask is the first self-custodial wallet to offer prediction markets as a built-in feature. By embedding Polymarket’s markets directly into an interface used by more than 140 million wallets, the companies aim to bring on-chain forecasting to a much larger audience.

Research groups have long noted that prediction markets often produce more reliable forecasts than polls because users stake their own money on expected outcomes. Markets range from sports and politics to crypto and cultural events.

Users can buy or sell positions, watch odds update in real time, and claim any resolved payouts directly to their wallet. All activity stays self-custodied, with MetaMask’s security stack managing keys and permissions.

The integration follows a partnership teased in October, part of MetaMask’s ongoing shift toward in-app trading. Over the past two months, the wallet has added perpetual futures via Hyperliquid (HYPE), upgraded its rewards program, and supported new ways to move assets across networks.

In November, Polymarket also pushed its reach into mainstream visibility after its odds began appearing in Google Search and Google Finance.
