At today's #ETHShanghai2025 Summit, Vitalik had a roundtable dialogue with Xiaofeng Buterin, Chairman of Wanxiang Blockchain.

Vitalik Buterin said that the potential of the prediction market goes far beyond investment tools and it may become the "third media" in the social cognitive system.

He cited Polymarket during the US election as an example, noting that many intellectuals who were previously critical of cryptocurrencies also used prediction markets to understand the true impact of events. "When I saw this kind of cross-disciplinary use, I realized it was a true success."

Vitalik believes that prediction markets can filter out biases in traditional media and social media, making prices the most authentic signals.

In the future, with the intervention of AI, the prediction market will expand from macro events to micro interactions, such as predicting the popularity of an article.
