The U.S. Supreme Court struck down the federal ban on sports betting in a 2018 decision, opening the doors for states to legalize it if they wish. Since then, 38 states and the District of Columbia have legalized sports betting in some form, many allowing online bets. Missouri is set to become the 39th state in December.

Six top sports betting stocks in 2025
As more states legalize sports betting, the market is growing quickly. Not only are new states easing restrictions, but betting is also growing more popular each year in states that have already legalized it. If you want to invest in this rapidly growing industry, here are six options to consider:
1. Flutter Entertainment

NYSE: FLUT
Key Data Points

NASDAQ: DKNG
Key Data Points
DraftKings (DKNG -1.73%) operates the second-largest online sportsbook in the U.S., accounting for about 25% of the market, according to its internal estimates. It currently operates in 25 states and Washington, D.C., and its online casino is available in five states.
DraftKings is solely an online operator in the U.S. and Canada. It doesn't have any brick-and-mortar casinos, so it's a pure play on the growth of online sports betting in North America. Given the expected expansion of online sports betting in the U.S. and Canada, its online-only presence gives the company great growth potential.
DraftKings is executing well and growing its market share quickly. It added 3 million active customers in 2024 despite strong competition from new entries into the market.
As a result, net revenue is growing quickly, and earnings before interest, taxes, depreciation, and amortization (EBITDA) growth is strong. In 2025, the company plans to introduce a tax surcharge in states with high taxes on sportsbooks, a move that could boost profits but may come at the cost of market share.
3. MGM Resorts
4. Caesars Entertainment

NASDAQ: CZR
Key Data Points
Caesars (CZR -15.26%) is best known for its Caesars Palace casino in Las Vegas, but after its acquisition by Eldorado (which took the Caesars name), it now operates more than 50 casinos across the U.S. The company then acquired William Hill, which pushed it into the online sportsbook market in the U.S. It rebranded William Hill's operations to Caesars Sportsbook.
The company operates in 32 jurisdictions in North America, 25 of which include online sports betting and five that include internet gaming. Management has cut back on aggressive ad campaigns, which has resulted in some share loss. However, the digital segment now generates positive EBITDA and could produce positive net income for the business.
Caesars will likely continue to focus on acquiring brick-and-mortar casinos to add to its growing portfolio. Meanwhile, it's building two more casinos in Las Vegas. After facing large setbacks due to the COVID-19 pandemic, its operations in Macao and Singapore also hold potential.
