For the first time since 2000, gambling on the Olympics is legal in the United States. We took the best odds available for each athlete on gambling aggregator Oddschecker, and have quick takes on a few events below. 

Note: there are odds available for several athletes that did not qualify in their events. While you can still place those very dumb bets, we tried our best to remove those athletes from this post.

Men's 100m	Odds to win
Usain Bolt	8/13
Justin Gatlin	2/1
Yohan Blake	16/1
Trayvon Bromell	16/1
Jimmy Vicault	16/1

Andre De Grasse	45/1
Wayde van Niekerk	50/1
Alonso Edward	60/1
Ameer Webb	70/1
Miguel Francis	80/1

Quick take: Bolt is even more unbeatable in the 200m than he is in the 100m, but 200m world leader LaShawn Merritt at 10/1 is pretty appealing.

​Quick take: Considering Rudisha was third at the Kenyan Trials and didn't crack the top three in either of his two Diamond League races, everyone else at 17/2 or longer is kind of spicy.
