Sam Altman’s World Expands into Prediction Markets with Polymarket Integration

9h ago

World, the digital identity project founded by OpenAI CEO Sam Altman and formerly known as Worldcoin, is broadening its reach into the prediction market sector by integrating with Polymarket.

The partnership introduces Polymarket directly into the World App ecosystem, marking a major step in the company’s strategy to merge digital identity, financial tools, and decentralized applications.

World App Adds Polymarket Mini App

World announced on Tuesday that its mobile wallet, World App, which already includes World’s decentralized identity tool, World ID, has integrated the Polymarket Mini App.

“World App users can download and access the new Mini App today in countries where Polymarket’s services are permitted,” the company said in its statement.

The feature allows users to place bets on prediction markets without leaving the World App, using Circle’s USDC stablecoin and World’s native token, WLD.

However, access remains restricted in certain jurisdictions. “Eligibility for Worldcoin tokens is restricted based on geography, age and other factors,” World noted, adding that the token is not available in restricted regions, including New York state.

The company further clarified that “World Assets and World Foundation are not responsible for the availability of WLD on third-party platforms, such as centralized or decentralized exchanges.”

100 Million Mini App Downloads and Growing

The integration comes as World celebrates a significant milestone — surpassing 100 million Mini App downloads earlier this month.

World’s Mini Apps, introduced in October 2024, are web applications built directly into the World App ecosystem.

As of March 2025, the company had at least 150 Mini Apps active on its platform, with over 10 million WLD (valued at around $8.8 million) transacted.

By July, the project had reached 14 million verified human users across 160 countries, and a total user base of 30 million.

Prediction Markets Reach Record Volumes

The timing of the Polymarket integration coincides with a global surge in prediction market activity.

According to data from Dune Analytics, weekly trading volumes across prediction markets surpassed $2 billion for the first time in mid-October, setting a new record.

Polymarket led the sector, accounting for 52.3% of all trading volume, while rival platform Kalshi followed closely with $950 million, or roughly 47% of total activity.

The growth has attracted institutional attention. Earlier this month, Polymarket secured a $2 billion investment from the Intercontinental Exchange, while Kalshi raised $300 million in a round led by Sequoia Capital and Andreessen Horowitz.

As prediction markets continue to expand, World’s integration with Polymarket positions the company at the intersection of digital identity, decentralized finance, and global prediction ecosystems.
