Here’s what happened in crypto today.

Today in crypto, the behavior of top Polymarket bettors has raised concerns about potential manipulation of the decentralized prediction market’s accuracy ahead of the United States presidential election on Nov. 5, the US has a 26 million strong “crypto voting bloc” going in the election, according to a survey, and the FBI claimed it arrested the man who hacked the SEC’s X account in January.

Polymarket whale raises Trump odds, sparking manipulation concerns

Former President Donald Trump’s rising odds in the 2024 United States presidential election have allegedly been significantly influenced by Polymarket user “Fredi9999,” a major bettor who holds more than $20 million worth of pro-Trump bets.

The revelation comes days after Cointelegraph reported that Trump’s Polymarket odds of winning the presidential elections rose to a record high of 60.2% on Oct. 16.

Trump’s growing lead has raised questions, as it appears to be unrelated to real-world events that could explain such a shift in public perception, according to Alex Momot, founder and CEO of Peanut Trade.

Momot told Cointelegraph:

“What’s paradoxical is that the situation on Polymarket is now influencing the real world, where many people believe what they see on the platform. The upcoming US presidential election will serve as a key example for assessing the reliability of prediction markets.”

As the election nears, the importance of evaluating potential manipulation in prediction markets is increasing, especially with less than three weeks remaining before Election Day.
