What is the MetaMask Polymarket integration?

MetaMask Polymarket integration embeds the Polymarket prediction‑market interface inside the MetaMask wallet, allowing users to trade on event outcomes directly while retaining self‑custody of assets and keys. The launch pairs prediction markets with in‑app perpetuals and a seasonal Rewards program to broaden on‑chain financial access.

How will MetaMask users trade on Polymarket inside the wallet?

The in‑wallet integration presents Polymarket markets within MetaMask’s interface. Users will be able to view markets, place positions, and settle outcomes without leaving the app. Trade execution and settlement remain onchain. According to TokenTerminal data, Polymarket has recorded near $20B in cumulative trading volume, reflecting significant liquidity in decentralized prediction markets.

MetaMask, the leading self‑custodial wallet developed by Consensys, announced an exclusive partnership with Polymarket, the world’s largest decentralized prediction market. This marks MetaMask’s first major expansion into on‑chain forecasting and event trading, and a deliberate step toward becoming a broader financial gateway for Web3 users.

The integration will allow users to participate in prediction markets directly within the MetaMask platform, enabling them to trade outcomes on topics ranging from crypto and politics to global events, all while maintaining full self‑custody. The move positions MetaMask as not just a wallet, but a gateway to decentralized speculation and information markets.

The move comes as prediction markets gain momentum as a new frontier for on‑chain finance. Platforms like Polymarket have seen near $20B in trading volume, according to TokenTerminal data. That scale supports deeper market selection and improved price discovery for event‑based instruments.

Rewards program: MetaMask will launch its Rewards program by the end of October, a seasonal point‑based system that incentivizes trading and stablecoin activity through perks such as $LINEA token distributions, fee discounts, and priority access to the upcoming MetaMask Metal Card. The program is designed to increase user engagement and to reward onchain activity inside the wallet.

Convergence in trading, speculation, and access

MetaMask’s updates build on a recent partnership with Hyperliquid, which introduced perpetual futures on mobile earlier in the month. The combination of in‑app perps and the Polymarket integration highlights a strategic expansion: turning MetaMask into a decentralized trading hub that provides advanced market tools without custody risk.

The approach mirrors a broader Web3 trend that merges accessible interfaces with sophisticated market mechanics. By offering perpetuals, prediction markets, and reward incentives natively, MetaMask seeks to serve both active traders and casual users exploring on‑chain opportunities.

MetaMask is also preparing for a potential token launch that company leadership has referenced publicly; these product additions can be viewed as ecosystem building ahead of any token distribution.

Frequently Asked Questions

Can MetaMask users keep custody of funds when using Polymarket inside the wallet?

Yes. Trades executed through the MetaMask Polymarket integration remain self‑custodial: private keys stay on the user’s device and settlements occur onchain. MetaMask acts as an interface and transaction signer, not as a custodian.

How quickly can markets settle on Polymarket within MetaMask?

Settlement timing depends on the underlying market and oracle resolution mechanism. Most markets settle once an event outcome is confirmed by the designated oracle. Users should review each market’s rules for finality and dispute windows before trading.

Key Takeaways

• Product expansion: MetaMask integrates Polymarket and in‑app perpetuals to broaden wallet functionality beyond custody.
• Onchain volume: Polymarket has approached $20B cumulative trading volume (TokenTerminal), indicating robust market activity that supports the integration.

Conclusion

The MetaMask Polymarket integration marks a notable shift: MetaMask is evolving from a pure wallet into a decentralized financial hub offering trading, earning, and market participation without forfeiting custody. As prediction markets and perpetuals gain traction, this integration will be an important test of native wallet‑based productization.
