Prediction markets have never been this popular, with more people making bigger bets on everything from the number of times Federal Reserve Chair Jerome Powell will say the word “inflation” to the question of whether President Donald Trump or Pope Leo XIV will get more Google searches in 2025. Meanwhile, major investors are buying up stakes in prediction companies. Last week’s episode of the Everybody’s Business podcast from Bloomberg Businessweek explored the reasons for this surge in interest, including the growing popularity of gambling and the light touch the current US administration has taken to regulating potentially sketchy financial markets. For this week’s episode, we wanted to understand what the people placing bets on markets such as Polymarket and Kalshi find so compelling. So we got in touch with a professional gambler—a longtime prediction markets junkie who has placed more than $400 million worth of bets using Polymarket, more than anyone in the site’s history. He goes by the name Domer (a pseudonym) and at any point might have 1,000 or more bets on prediction market sites, ranging from wagers of a few thousand dollars to as much as $1 million, roughly the sum he put on Taylor Swift’s new album sales. Also this week, Businessweek columnist Amanda Mull talks about the premium credit card war in which American Express and Chase are competing for wealthy consumers and battling over who can offer the best perks and charge the highest fees. Mull explains what the phenomenon says about the US economy—and which cards offer the best value.
