MetaMask Prediction Markets Overview

MetaMask Prediction Markets brings Polymarket directly into the MetaMask Mobile app. You can buy Yes or No shares on sports, politics, crypto, finance, and tech events without leaving your wallet. Shares trade between 0 and 1 dollar. If your pick wins, it redeems for 1 dollar after resolution. If it loses, the shares expire worthless.

This feature targets people who already hold crypto in MetaMask and want to trade on real-world outcomes. Active MetaMask users who want swaps, perps, and event contracts in one place get direct value here. Crypto traders with idle EVM tokens can put those assets to work on event contracts. You stay self-custodial the entire time, which matters for anyone who avoids centralized platforms.

One-tap funding handles the heavy lifting. You pick any EVM token like ETH or USDC, choose an amount, and confirm. The system bridges the value into your prediction balance and creates a linked Polymarket account if you do not have one yet. From there, you browse markets inside the Predictions section, filter by topic, tap a market, check the rules and end date, then select an outcome and enter your stake. The app shows your potential payout before you confirm. Open positions appear on the home screen with live unrealized profit and loss, and you can add shares or cash out before resolution at any point.

Settlement runs on Polygon. Correct shares get claimed into your available balance, and withdrawals move USDC.e to your main MetaMask account or settle as mUSD through the Money Account. Gas for claims and withdrawals is covered, so you never need the native Polygon token. Funding works with tokens on Ethereum, Arbitrum, Base, Linea, Polygon, Optimism, and Avalanche.

What separates this from using Polymarket directly is the integration. You skip separate account creation, external funding steps, and app switching. Trading takes two taps inside a wallet you already use. Every qualifying trade also earns MetaMask Rewards points at a rate of 2 points per dollar traded on fee-charging markets.

The tradeoff is cost. A fixed 4 percent fee applies to every trade, split between MetaMask and Polymarket. Polymarket adds a variable taker fee between 0 and 7 percent depending on market type, share price, and trade size. The combined cost appears before you confirm. Going directly to Polymarket avoids the 4 percent fee but requires a separate setup and funding flow.

The feature is unavailable in the United States, United Kingdom, France, Canada, Belgium, Poland, Singapore, Australia, Taiwan, Thailand, Germany, Romania, and other jurisdictions listed in Polymarket terms. You need MetaMask Mobile version 7.73.2 or higher.

Is MetaMask Prediction Markets safe & legit?

<strong>Consensys</strong>, the company behind the original Ethereum wallet since 2016, built and maintains MetaMask, and the prediction feature runs on Polymarket's existing oracle and settlement infrastructure. The self-custodial design means your keys never leave your device, and the broader Polymarket community trusts the underlying market resolution process. <strong>No major red flags are known</strong> beyond standard prediction market risks like thin liquidity, price impact on large trades, and potential regulatory changes in restricted jurisdictions.
