Polymarket integrates with World App as prediction markets surge
World App—the mobile wallet and decentralized identity platform tied to Sam Altman’s World project—has added Polymarket as a native Mini App, expanding access to crypto-powered prediction markets. The integration comes amid a global boom in prediction market activity, which recently hit record weekly trading volumes.
Polymarket Mini App arrives on World App
World announced that users can download and use the Polymarket Mini App within World App in jurisdictions where Polymarket is permitted. The move brings one of the largest decentralized prediction markets directly into World’s ecosystem, letting users access markets without leaving their World wallet.
World App users can bet on Polymarket with USDC and WLD
The integration enables World App holders to place bets on Polymarket using Circle’s USDC stablecoin and World’s native token, WLD. By supporting USDC, the Mini App lowers friction for mainstream crypto users, while WLD integration deepens utility for World’s native asset. World noted that eligibility for WLD distribution is limited by geography, age and other rules; residents of restricted locations such as New York state currently cannot receive WLD via World App.
World also clarified that World Assets and World Foundation are not liable for the availability of WLD on third-party platforms, including centralized or decentralized exchanges. Given regulatory differences across regions, Polymarket itself remains subject to localized restrictions and is still navigating its U.S. relaunch even after regulatory review.
Mini Apps accelerate World’s platform growth
The Polymarket launch follows a milestone for World: more than 100 million Mini App downloads as of early October. Mini Apps are web applications embedded natively within World App, offering services from finance to entertainment while leveraging World ID for decentralized identity verification.
Since debuting Mini Apps in October 2024, World has attracted a large and growing user base. By mid-2025 the platform reported millions of verified human users across over 160 countries, with tens of millions more engaging with the wider World network. Transactions using WLD inside Mini Apps have already reached meaningful volumes, signaling rising on-chain activity.
Prediction markets hit new highs at $2 billion in weekly volumes
The World–Polymarket tie-up coincides with a surge in global prediction market trading. Data aggregated on Dune Analytics by Dunedata shows that weekly trading volumes across prediction markets topped $2 billion in mid-October — a new all-time high. Polymarket led the market, accounting for roughly half of total volume, while rivals like Kalshi captured major shares as well.

Institutional interest is growing alongside retail activity. Polymarket secured a headline-grabbing $2 billion investment from the Intercontinental Exchange on Oct. 7, while Kalshi raised $300 million in a round led by Sequoia Capital and Andreessen Horowitz and announced expansion into dozens of new markets.
What this means for crypto and prediction markets
Bringing Polymarket into World App reduces onboarding friction and strengthens use cases for both USDC and WLD in prediction markets. For traders and observers in the cryptocurrency and blockchain space, the integration is notable: it combines identity-backed wallets with a high-liquidity market venue at a moment when prediction trading is seeing institutional capital and record user interest.
As regulatory clarity evolves, platforms that balance compliance with on-chain UX — and support mainstream assets like USDC — are likely to attract continued growth. For market participants, monitoring which jurisdictions support Polymarket and how WLD distribution rules change will be important for accessing these new on-chain markets.
