“Prediction markets, including Kalshi and Polymarket, are exploding in popularity. Kalshi alone saw over $1 billion in trading volume on Super Bowl Sunday. Remarkably, more than $100 million was wagered on what song Bad Bunny would play first during his halftime show. That kind of market has raised concerns about insider trading. Not only is Bad Bunny in control of which song is played, but this information is also known in advance by dancers, musicians, crew, and anyone who happened to be around during rehearsals. This is likely why, just before the big game, Kalshi CEO Tarek Mansour announced a laundry list of efforts to crack down on insider trading.” (02/12/26)
