What is Piggy Blitz?

Since the landmark Supreme Court ruling in 2018 that allowed states to legalize sports betting, gambling has become increasingly intertwined with American culture.

Paired with the recent rise of prediction markets—which allow traders to stake money on everything from sporting events to pop culture outcomes—Americans are risking more money on casino-like activities than ever before.

Buffett has repeatedly raised concerns regarding the mainstreaming of gambling and its marketing under the guise of investing. In May, he targeted prediction markets and traders speculating on short-term instruments like 30-minute bitcoin options.

The lesson is simple: gambling still attracts capital when the money is visible. It is less attractive when the payoff lies far in the distance.

The biggest new uncertainty in US sports betting is prediction markets. The American Gaming Association estimates that Americans will legally wager $29.5 billion in betting handle through US regulated commercial sportsbooks during the 2026 NFL season, broadly unchanged from the $29.4 billion handle recorded in 2025. These figures refer to the amount wagered, not sportsbook revenue.

Robinson calls prediction markets “the main event”. His argument is not simply that US customers are moving from sportsbooks to prediction markets. The more important point is that sportsbooks no longer have the relatively protected market that was once assumed.
