According to TechFlow, on October 18, Cointelegraph reported that as the US presidential election approaches, the behavior of top bettors on Polymarket has raised concerns that the prediction market may be manipulated. Former President Donald Trump's odds of winning the 2024 US presidential election have continued to rise, largely influenced by Polymarket user "Fredi9999", a large bettor who holds more than $20 million worth of pro-Trump bets. Alex Momot, founder and CEO of Peanut Trading, said Trump's expanding lead has raised questions because it does not seem to be related to real-world events that can explain the shift in public opinion. Currently, Trump's odds have risen to 60.2% on Polymarket. Analysts point out that such market dynamics may affect the public's view of the election results and emphasize the need to evaluate prediction market manipulation.
