Around 370,000 people are making bets worth more than $90 million on politics at Polymarket, according to an analysis of data from Dune Analytics, conducted by The Washington Post. Domestic matters, including the content of his State of the Union address and the next Federal Reserve Chairman, can also be wagered on. However, the increasing amount of money being wagered has increased concerns over the potential for insider trading on significant global events.
