You can't gamble on death.

U.S. lawmakers have introduced the “DEATH BETS Act” to ban prediction markets that allow traders to bet on war, assassinations, or people dying.
Platforms were already seeing hundreds of millions wagered on geopolitical events and even specific individuals.
That creates a dangerous incentive.
When money is on the line, bad actors may try to make the prediction come true.
Banning these markets removes a perverse financial motive tied directly to violence.
At least some of it.
