As with any industry, there are pluses and minuses to investing in sports betting stocks.
Sports betting is a well-established industry in many countries, but the U.S. -- one of the world's biggest potential markets -- is still in its infancy and remains in flux. The trend favors more U.S. states legalizing sports betting, providing a tailwind for sports betting companies. Investors will want to consider each company's market position and competitive advantages, such as strong brand, scale, and data, to protect them from threats like prediction markets. There are multiple great stocks to choose from amid the growing industry.
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, 39 states, the District of Columbia, and Puerto Rico have legalized sports betting in some form, many allowing online bets.
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 five options to consider:




| Name and ticker | Current price | Market cap |
|---|---|---|
| Flutter Entertainment Plc (NYSE:FLUT) | $92.38 | $16.1 billion |
| DraftKings (NASDAQ:DKNG) | $25.00 | $12.4 billion |
| MGM Resorts International (NYSE:MGM) | $36.97 | $9.5 billion |
| Caesars Entertainment (NASDAQ:CZR) | $27.80 | $5.7 billion |
| Penn Entertainment (NASDAQ:PENN) | $16.20 | $2.2 billion |
Flutter Entertainment (FLUT -1.57%) is a global sports betting and gaming company. Its U.S. brand, FanDuel, is the country's most popular online sports betting site.
FanDuel's 2025 share of online sports betting is about 44% in the markets it operates in. That's only a slight drop from its 2023 estimate of 47%, despite the growing market size and competition.
FanDuel's sportsbook is available in 23 states, and its online casino is available in five. Flutter consistently reinvests its profits in customer acquisition and in expanding the market for sports betting and internet gaming. The results speak for themselves, with leading market share and strong top-line growth.
Outside the U.S., Flutter is also the leading operator in the more mature U.K. and Irish markets, which are the largest in Europe. As more betting shifts online, Flutter is positioned to win a greater share. In Australia, it operates SportsBet, which Flutter claims holds a 45% market share of online sports betting. It continues to expand internationally through strategic acquisitions such as NSX (Brazil) and Snai (Italy).
DraftKings (DKNG -0.60%) operates the second-largest online sportsbook in the U.S., accounting for about 34% of the market. 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, the company's online-only presence offers significant growth potential. Management expects its total addressable market to grow to between $55 billion and $80 billion by 2030.
DraftKings is executing well and growing its market share quickly. It added 3 million active customers in 2024 and another 800,000 in 2025. As a result, net revenue is growing quickly, and earnings before interest, taxes, depreciation, and amortization (EBITDA) growth is strong.
MGM Resorts (MGM +0.43%) is one of the biggest casino operators in the U.S. and Macau. It also jointly owns BetMGM's U.S. operations with Britain's Entain, and in 2022, it acquired LeoVegas, a leading sports betting and iGaming operator in 10 European countries. MGM uses LeoVegas to offer BetMGM-branded services outside the U.S.
BetMGM's growth slowed in the second half of 2025. Its sportsbook handle grew just 16% for the full year but only 3% in the fourth quarter. That said, it's increasingly profitable as it executes its strategy of focusing on profitable players.
MGM's brick-and-mortar operations will expand to Japan in the next decade, with the opening of the country's first legal casino in Osaka in 2030. That could be a big opportunity in the long run. In the meantime, operations in the U.S. and Macau have recovered and are moving past pre-COVID-19 pandemic levels.
Caesars (CZR +2.36%) 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, resulting 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. After facing large setbacks due to the COVID-19 pandemic, its operations in Macau and Singapore also hold potential.
Penn (PENN +2.34%) operates 42 casinos across 19 states and has moved into the world of online sports betting with the acquisition of a 36% stake in Barstool in 2020 and theScore in 2021. In 2023, it partnered with ESPN to launch ESPNBet, rebranding some of its retail locations with the ESPNBet name. Both sides terminated the agreement in 2025, after which Penn rebranded its online sportsbook as theScore.
Its online sportsbook has licenses in 20 U.S. jurisdictions and Ontario, and its online casino is available in four states and Ontario. Of its brick-and-mortar casinos, 32 operate retail sportsbooks across 15 states.
Penn has been less aggressive in marketing its online sportsbook, sticking to more targeted ads versus nationwide brand campaigns. It's also benefited from Barstool's and theScore's media segments for more organic advertising of its sportsbook.
As a result, the company has been more profitable than other online sportsbooks, which must invest heavily in marketing. With operations confined to the U.S. and Canada, Penn is more of a pure play on the continued expansion of sports betting in North America.
