The integration between Polymarket and Sam Altman’s World App has sparked a major wave across prediction markets, with weekly trading volumes surpassing $2 billion, the highest ever recorded.
As the market grows in both participation and legitimacy, the collaboration marks a significant step toward merging digital identity and decentralised trading.
World App, developed by Tools for Humanity, has evolved into a hub for blockchain-based applications. By adding Polymarket’s Mini App, it allows users to access prediction markets directly within their digital wallet ecosystem using both USDC and Worldcoin’s WLD tokens.
This move not only simplifies access to speculative trading but also positions World as an expanding platform for decentralised utility beyond identity verification.
World App Expands Into Prediction Markets
World App’s decision to integrate Polymarket reflects the growing interest in real-world prediction ecosystems that combine accessibility, transparency, and global participation.
The Polymarket Mini App allows users to bet on outcomes ranging from global politics to technology trends directly within World App. Transactions can be completed using USDC or WLD, aligning digital identity with real-time financial engagement.
Polymarket still faces regulatory limitations in certain jurisdictions. While it continues to operate internationally, its re-entry into the United States is pending regulatory clearance from the Commodity Futures
Trading Commission. Despite this, its partnership with World shows clear intent to broaden user access globally.
For World, the timing of this launch coincides with its growing ecosystem. By early October 2025, World reported more than 100 million Mini App downloads and over 14 million verified human users across 160 countries. The platform’s vision extends beyond storing credentials.
It seeks to connect verified users with practical blockchain-based services. The inclusion of Polymarket represents a natural extension of this approach, offering a way for verified digital identities to engage with transparent on-chain markets.
WLD token distribution remains limited by region, age, and compliance rules, with access restricted in certain countries such as the United States.
World Assets and the World Foundation also clarified that they are not responsible for the token’s availability on external exchanges, reinforcing the decentralised structure of the system.
The rapid adoption of Mini Apps highlights how digital identity systems are evolving into gateways for new forms of participation. Each integration, including Polymarket, adds utility and trust to the network, driving engagement across both the identity and financial spheres.
Prediction Markets Surpass $2 Billion in Weekly Volumes
The timing of this integration aligns with a remarkable surge in prediction market activity. Data from Dune Analytics shows that weekly trading volumes in mid-October exceeded $2 billion for the first time, a clear signal that the sector is maturing into a substantial financial segment.
Polymarket remains at the forefront of this movement, contributing over 50% of the total volume. Its rival Kalshi follows closely, recording around $950 million in trades during the same period.
This rivalry has created an ecosystem of innovation where user experience, regulation, and credibility are being tested in real time.
Institutional attention has also intensified. On October 7, Polymarket received a $2 billion investment from the Intercontinental Exchange, an entity best known for owning the New York Stock Exchange.
A few days later, Kalshi secured $300 million in a funding round led by Sequoia Capital and Andreessen Horowitz, signalling that major investors are viewing prediction markets as a legitimate extension of modern finance.
Beyond raw trading numbers, prediction platforms have become centres of information aggregation, often reflecting public sentiment ahead of political or economic events.
The integration of Polymarket within World App extends this idea further by connecting identity-verified participants to decentralised forecasting systems.
This could pave the way for a future where real-time, human-verified data becomes a central part of financial and social prediction networks.
For users, this evolution simplifies participation. Instead of managing multiple wallets or navigating standalone platforms, they can now interact with prediction markets directly within an environment already familiar to millions, the World App.
By bridging identity verification with on-chain prediction tools, the integration could encourage more responsible participation and improve confidence among regulators and new users alike.
Conclusion
The partnership between Polymarket and World App represents more than just another app integration. It signals a shift toward connecting verified digital identity with decentralised financial participation.
With record-breaking trading volumes and growing institutional interest, prediction markets are entering a new phase of mainstream recognition.
As World App continues to expand its Mini App ecosystem, this collaboration may redefine how identity and decentralised trading interact within the global blockchain landscape.
