What Happened to DraftKings vs. FanDuel?

The rivalry between DraftKings and FanDuel, two titans of the online gaming industry, traces back to their origins in daily fantasy sports (DFS) in the early 2010s. Both companies rapidly gained traction by offering cash prize contests based on player performance, fueling a massive marketing war that saw their advertisements saturate sports broadcasts. This aggressive expansion, however, soon drew scrutiny, leading to accusations of illegal gambling and an 'insider trading' scandal in 2015 when a DraftKings employee inadvertently won a large sum on FanDuel using proprietary data.

The ensuing legal battles were a critical turning point. State attorneys general, notably in New York, filed lawsuits alleging that DFS constituted illegal gambling, forcing both companies to defend their business model and temporarily cease operations in some states. Amidst this regulatory uncertainty, DraftKings and FanDuel announced a blockbuster merger in November 2016, aiming to consolidate their market dominance and gain regulatory clarity. However, the Federal Trade Commission (FTC) moved to block the deal in June 2017, citing concerns that the combined entity would control over 90% of the U.S. daily fantasy sports market, thereby stifling competition. The merger was ultimately called off in July 2017.

The landscape dramatically shifted in May 2018 with the U.S. Supreme Court's repeal of the Professional and Amateur Sports Protection Act (PASPA), which had effectively banned sports betting outside of Nevada. This decision opened the floodgates for states to legalize sports betting, a development both DraftKings and FanDuel had anticipated and quickly capitalized on. FanDuel was acquired by Irish bookmaker Paddy Power Betfair (now Flutter Entertainment) in 2018, providing it with significant capital and international expertise. DraftKings, meanwhile, went public in 2020 through a $3.3 billion SPAC merger.

As of August 2026, the two companies continue their fierce competition, now primarily in the legal online sports betting and iGaming sectors across numerous U.S. states. FanDuel, under Flutter Entertainment, generally maintains a slight lead in overall market share for both sports betting (39% in Q2 2026) and iGaming (27% in Q2 2026) in the U.S.. DraftKings remains a strong second, with both companies consistently combining for over 70% of the market share in states where they both operate.

Recent developments in 2026 highlight their continued evolution and challenges. Both companies reported their Q2 2026 earnings in early August, revealing a complex picture of growth and profitability. DraftKings reported a 15% increase in Sports Consumer Volume to $13.1 billion but a 5% decrease in revenue to $1.44 billion, attributing the decline to customer-friendly sport outcomes and increased promotional spending. The company also reported a net loss of $67.6 million.. FanDuel's parent company, Flutter Entertainment, also saw its U.S. sports betting revenue drop 15% year-over-year in Q2 2026, with overall U.S. revenue down 6% to $1.683 billion, similarly impacted by bettor-friendly outcomes and increased marketing spend, particularly around the FIFA World Cup.

Both DraftKings and FanDuel are heavily investing in and expanding into prediction markets, a new frontier in online wagering. DraftKings launched its 'Predictions' product in December 2025 and reported over 600,000 prediction customers by mid-2026, viewing it as a core growth opportunity.. FanDuel also launched 'FanDuel Predicts' in December 2025, initially in five states, primarily as a customer acquisition channel ahead of broader sports betting regulation.. This expansion has led to new regulatory discussions, with both companies urging federal regulators to establish clear consumer protection and market integrity standards for prediction markets.

Legal scrutiny also persists, with class-action lawsuits filed against both companies in 2025 and 2026 alleging deceptive practices, false advertising, and illegal operation of daily fantasy sports contests in states like California where online sports betting is prohibited.. Despite these challenges, both DraftKings and FanDuel renewed their multi-year partnerships with the NFL in August 2026, solidifying their positions as official sports betting partners alongside newcomer Fanatics.. The rivalry remains intense, with both companies constantly innovating and adapting to a rapidly evolving regulatory and technological landscape.
