Men's 50m Freestyle Swimming odds at the Tokyo Olympics have Caeleb Dressel as a "lock" priced at -1000.  The problem of course is that you have to bet $100 to win $10 (the $100 will be refunded unless he fails to win the gold, but it's just a measly $10 profit).

The American is a two-time Olympic gold medalist and currently holds the world records in the 100 meter butterfly (both long course and short course), 50 meter freestyle (short course), and 100 meter individual medley (short course).

Being a favorite in three individual events and potentially four relays, Dressel has the opportunity to rack up Phelps-like medals.

“I don’t think that falls on my shoulders alone,” Dressel said of succeeding Phelps. “Michael was one guy within USA Swimming, but he wasn’t USA Swimming. … I don’t think it was Michael alone and it’s certainly not myself alone.”
