On November 9, Vitalik released a new article "From Prediction Markets to Information Finance", saying that he has been a close supporter and follower of Polymarket this year, and that the prediction market is one of the most exciting Ethereum applications for him. Vitalik believes that Polymarket has two sides, on the one hand, it is a betting site for participants, and on the other hand, it is a news site for everyone else. When the election results gradually fell, while many experts and news sources have been luring viewers in the hope that they will hear the news in Harris's favor, Polymarket directly revealed the truth that the probability of Trump winning the election has reached 95%. With real investment from users, the market can realize what the truth is closer to. In addition, prediction markets can also use finance as a way to coordinate incentives in order to provide valuable information to the audience. Information finance solves the problem of trust that people actually have. A common concern of this era is the lack of knowledge and not knowing who to trust in political, scientific and business environments. Information finance applications can help be part of the solution. He expects that one technology that will drive information finance in the next decade is artificial intelligence.
