On November 9th, Vitalik released a new article 'From prediction market to information finance', indicating that he has been a close supporter and follower of Polymarket this year, and prediction market is one of the most exciting Ethereum applications for him. Vitalik believes that Polymarket has a dual nature, providing a betting site for participants on one hand, and a news site for everyone else on the other. As the election results gradually unfolded, despite many experts and news sources trying to lure the audience into hearing favorable news for Harris, Polymarket directly revealed the truth that Trump's probability of winning had reached 95%. The real money invested by users can make the market realize what the truth is closer to. In addition, prediction market can also use finance as a way of coordinating incentive mechanisms to provide valuable information to the audience. Information finance addresses the trust issues that people actually have. A common concern of this era is the lack of knowledge and not knowing who to trust in the political, scientific, and business environments. Information finance applications can help be part of the solution. He expects that the technology driving the development of information finance in the next decade will be artificial intelligence.
