About 164 million adults, or two-thirds of the U.S. population, live in states where they can legally bet on Team USA (and plenty of other countries) at the Paris Olympics. That’s up from 97 million, or 40% of the population, from the pandemic-delayed 2021 Tokyo Olympics.

The 2024 Games, which officially opened yesterday, will be the most heavily bet on Olympics since the Professional and Amateur Sports Protection Act (PASPA) was overturned by the Supreme Court in 2018, a decision that allowed all states to offer Nevada-type sports wagering.
