According to industry data, DraftKings and FanDuel continued to dominate the domestic market in 2025, controlling 74% to 80% of the online handle. While a recent ranking named Boston-based DraftKings as the top mobile app, savvy bettors frequently look beyond domestic options to find the best sportsbooks for U.S. players in order to secure higher betting limits and sharper lines.
DraftKings App Crowned King
DraftKings may play second fiddle to FanDuel in terms of popularity, with a market share of 28% to 34% compared to FanDuel’s 38% to 44% of the national sportsbook market, but its app was again named the best in the business according to Eilers & Krejcik Gaming’s latest H1 2026 sportsbook app rankings.
While market access varies by region—as detailed in our localized state betting guides—DraftKings generated approximately $6.1 billion in revenue in 2025, second only to the industry leader FanDuel, which delivered roughly $7.05 billion last year.
According to the EKG Line newsletter, the positive results portend increased success for the nation’s No. 2 sports betting operator, stating, “So, what can we learn from the latest round of results? DraftKings topped FanDuel for the fourth consecutive report, suggesting the share gap between the two may continue to narrow throughout 2026.”
FanDuel claimed the No. 2 spot in the EKG Line newsletter’s assessment. The firm’s rankings have often aligned with future market-share trends, suggesting the industry’s two largest operators remain well-positioned to strengthen their hold on the market.
Fanatics rounded out the top three for the fourth report in a row. Testers pointed to the app’s smooth performance, intuitive design, and FanCash rewards program as major factors behind its strong showing.
Additional Sportsbook Rankings
Some of the other leading brands are experiencing massive changes, including Caesars, the iconic Las Vegas gaming brand, poised to be acquired by billionaire Tilman Fertitta and his Fertitta Entertainment. Meanwhile, Barry Diller’s People Inc. has made an offer for MGM Resorts.
Yet, despite these developments, significant changes to either company’s betting products appear unlikely in the near term. That stability may benefit Caesars, which earned a fourth-place ranking in the latest report. BetMGM, however, moved in the opposite direction, slipping to eighth place in the EKG rankings.
Two brands stood out among the remaining operators. Hard Rock Bet returned to the top five, while theScore Bet received praise for a strong relaunch in the U.S. market. Testers noted that the sportsbook made a positive impression under its updated branding following the conclusion of the ESPN Bet partnership between Penn and Disney.
Bet365 Loses Ground
One of the biggest surprises in EKG’s report was bet365’s drop to sixth place. Testers reported concerns about the platform’s overall design and user experience. The timing is notable, as the company is actively expanding its North American presence. Bet365 entered Michigan in mid-April and reportedly invested more than $27 million in promotional spending during its first two weeks in the state.
The operator is also preparing to launch in Alberta when the province’s regulated online casino and sportsbook market opens on July 13. At the same time, bet365 has introduced a new branding campaign in the United States and recently launched bet365 Fantasy Sports. The company hopes these initiatives will help attract new customers ahead of the upcoming World Cup.
