Summary

It reported that through the collaboration between 'World (WLD)' and Polymarket, World App users can directly participate in prediction market trading using USDC or WLD.
World App said that with Mini App downloads surpassing 100 million and a cumulative trading volume of 10 million WLD, its user base and trading scale are rapidly expanding.
Polymarket accounts for 52.3% of weekly prediction market trading volume and is leading the market, raising attention as to whether this collaboration will strengthen World's position in the prediction market.

The digital identity project 'World (WLD)', led by OpenAI CEO Sam Altman, has teamed up with prediction market platform Polymarket to introduce a new feature.

According to Cointelegraph on the 22nd (local time), World’s mobile application 'World App' combines a digital wallet with the identity verification tool 'World ID', and from that day it integrated the Polymarket Mini App.

With this integration, World App users can access Polymarket directly within the app and trade on prediction markets using USDC (Circle-issued stablecoin) or WLD.

World said, "Use of WLD may be restricted depending on requirements such as country and age, and in some jurisdictions such as the state of New York, distribution of WLD through the World App is not possible."

This integration took place shortly after the Mini App downloads of the World App surpassed 100 million. Since World first introduced the Mini App feature in October 2024, as of March 2025 more than 150 apps have been registered, and cumulative trading volume reached 10 million WLD. Currently, more than 30 million people from 160 countries have registered on the World platform, of which 14 million are counted as 'real-name users' who have completed biometric verification.

This collaboration reflects the rapid growth of the prediction market sector. According to Dune Analytics, worldwide weekly trading volume for prediction markets surpassed $2 billion for the first time in mid-October.

Among them, Polymarket accounted for 52.3% of the total, leading the market, while competitor Kalshi recorded $950 million (47%).
