Timeline (last 90 days)
The theoretical basis of prediction markets is the "efficient market hypothesis" and the "wisdom of crowds," holding that when there are economic incentives, mispricing will be quickly corrected by arbitrageurs and prices will approach the true probability.
The Efficient Market Hypothesis (EMH) was systematically proposed by economist Eugene Fama in 1970.
The core proposition of the Efficient Market Hypothesis is that stock prices already fully reflect all available public information, and therefore analysis based on public information cannot consistently generate excess returns.
The Efficient Market Hypothesis was systematically formulated by University of Chicago economist Eugene Fama in 1970 and exists in three forms: weak, semi-strong, and strong.
