DraftKings and FanDuel Cement Dominance in Exploding U.S. Sports Betting Market

The U.S. sports wagering landscape underwent a profound transformation following the U.S. Supreme Court's landmark decision in 2018 to strike down the Professional and Amateur Sports Protection Act of 1992 (PASPA). This pivotal ruling liberated states to individually regulate and legalize sports betting, unleashing a wave of expansion that has seen the majority of U.S. jurisdictions now offering legal wagering opportunities. In this rapidly evolving environment, two companies, DraftKings and FanDuel, have ascended to a commanding position, together securing an estimated 70% to 80% of the nation's betting market share.

DraftKings, originating as a daily fantasy sports (DFS) provider, was established in Boston, Massachusetts, in 2012 by founders Jason Robins, Matthew Kalish, and Paul Liberman. Its early growth was bolstered by an investment from Major League Baseball (MLB) in 2013, coinciding with the confirmation in early 2014 that it had awarded $50 million in prizes to DFS players during 2013. The company secured a $41 million funding round in August 2014 and forged significant DFS service partnerships with the National Hockey League (NHL) later that year, followed by another with MLB in April 2015. A substantial $300 million funding round in July 2015 saw participation from Fox Sports, Kraft Group, and Wellington Management. Following the PASPA repeal in 2018, DraftKings swiftly launched its inaugural online sportsbook in New Jersey. By April 2020, DraftKings became a publicly traded entity through a reverse merger valued at $3.3 billion, involving Diamond Eagle Acquisition Corp. and SBTech Global Ltd. Despite reporting losses in 2024, a strategic $500 million loan sustained its expansion. Recent financial disclosures in February, detailing 2025 results, revealed a Q4 revenue of nearly $2 billion, marking a 43% year-over-year increase, with total 2025 revenue reaching $6.05 billion, up from $4.77 billion in 2024. The platform reported 10.9 million unique customers in Q4 2025, with future plans prioritizing prediction markets.

FanDuel’s journey also began in the DFS sector, having been founded in Edinburgh, Scotland, in 2009 by Nigel Eccles, Lesley Eccles, Tom Griffiths, Chris Stafford, and Rob Jones. The company pivoted to DFS after initially operating a news prediction website called Hubdub. Early capital injection included $1.2 million from Scottish Enterprise and Pentech Ventures. Subsequent funding rounds included $11 million (Series C, 2013), $70 million (Series D, 2014), and $275 million (Series E, 2015), culminating in a valuation exceeding $1 billion within a decade. A proposed merger with DraftKings in late 2016, aiming to serve over 5 million customers, was ultimately abandoned in June 2017 after the Federal Trade Commission (FTC) voiced concerns over a potential 90% DFS market monopoly. Ahead of the PASPA repeal, Irish bookmaker Paddy Power Betfair (now Flutter Entertainment) announced its acquisition of FanDuel. This led to the merger of FanDuel with Paddy Power Betfair’s U.S. operations on July 11, 2018, forming the FanDuel Group, which promptly opened its first branded sportsbook at the Meadowlands Racetrack in New Jersey. By December 2020, Flutter Entertainment had increased its stake in FanDuel Group to 95% in a $4.1 billion transaction. In November 2025, FanDuel expanded its offerings into prediction markets across five states. The company reported a 33% increase in U.S. revenue for Q4 2025 and 5% year-over-year growth in average monthly players, along with a 41% sportsbook GGR share and 28% iGaming GGR share. CEO Amy Howe highlighted the company's strong performance, noting a 70% share of market EBITDA since 2018 and encouraging early engagement with its nationwide FanDuel Predicts rollout.

Both companies' entrenched market positions underscore their leadership in the burgeoning U.S. iGaming and sports betting sectors. A recent report by Research and Markets indicates that the U.S. betting industry, valued at $91.97 billion in 2025, grew to $102.16 billion in 2026 and is projected to reach $205.64 billion by 2032, exhibiting a compound annual growth rate (CAGR) of 12.18%. This growth, driven by technological advancements, evolving regulations, and shifting consumer behaviors, positions DraftKings and FanDuel to significantly capitalize on the expanding market while maintaining their competitive rivalry at the helm of the industry.
