World App integrates Polymarket as prediction markets surge
World, the digital identity project founded by OpenAI CEO Sam Altman and formerly known as Worldcoin, is expanding into prediction markets through a new integration with Polymarket.
The company announced on Tuesday that World App, its flagship mobile application that combines a self-custodial wallet with its World ID identity system, has launched the Polymarket Mini App, allowing users to access prediction markets directly from within World App, reports Cointelegraph.
“World App users can download and access the new Mini App today in countries where Polymarket’s services are permitted,” the company said. The integration enables users to place bets on real-world events using Circle’s USDC stablecoin or Worldcoin (WLD) tokens. However, due to regulatory restrictions, Polymarket remains unavailable in the United States pending its full relaunch following U.S. Commodity Futures Trading Commission (CFTC) approval.
World App’s rapid growth and Mini App ecosystem
The integration follows a major milestone for World App, which recently surpassed 100 million Mini App downloads in early October. Introduced in October 2024, Mini Apps are web-based applications embedded directly in World App, allowing users to access services like payments, DeFi, and now prediction markets without leaving the platform.
By March 2025, World App hosted over 150 Mini Apps, with 10 million WLD (worth $8.8 million) transacted across its ecosystem. As of July, the project reported 14 million verified unique human users and a total user base of 30 million across 160 countries, reinforcing its position as one of the fastest-growing decentralized applications globally.
World emphasized that eligibility for WLD tokens remains limited based on age, geography, and regulatory compliance, noting that distribution remains unavailable in restricted jurisdictions, including New York State.
Prediction markets hit record $2B in trading volume
The partnership comes amid a boom in global prediction markets. Data from Dunedata (Dune Analytics) shows that weekly trading volumes surpassed $2 billion in mid-October, setting a new all-time high. Polymarket dominated with 52.3% of total volume, while competitor Kalshi accounted for roughly $950 million.
Polymarket’s rise has also attracted major institutional backing — on October 7, the company secured a $2 billion investment from the Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange.
With this integration, World App is positioning itself at the intersection of digital identity, on-chain finance, and predictive analytics, offering users verified participation in decentralized markets. Analysts view this move as a strategic expansion for both World and Polymarket, further blurring the line between Web3 identity solutions and financial market innovation.
