What Is the Most Money Someone Has Won at a Casino?

The most money that someone has won at a casino is $40 million. This was won by an anonymous gambler at the Excalibur Casino in Las Vegas.

The gambler wagered $100,000 on a single roll of the dice and won. The odds of winning this bet are 1 in 3,000,000, so it is a very rare occurrence.

PRO TIP:The most money ever won at a casino is reportedly over 39 million dollars, which was won by an anonymous gambler playing baccarat at the Casino de Monte Carlo in Monte Carlo, Monaco in 2011. However, it is important to remember that these types of wins are extremely rare and are not a reliable way to make money.

While $40 million is the largest amount of money ever won at a casino in one bet, there have been other large wins. In 2011, a man named Don Johnson won $15 million playing blackjack at the Tropicana Casino in Atlantic City.

And in 2012, another anonymous gambler won $17 million playing slots at the Cosmopolitan Casino in Las Vegas.

So while winning millions of dollars at a casino is certainly rare, it does happen from time to time. And when it does, it makes for some pretty big headlines.
