Caesars Sportsbook

History & Founding

Caesars Sportsbook was established as a brand in 2021 following Caesars Entertainment’s $3.7 billion acquisition of the U.S. assets of William Hill, the British bookmaker founded in 1934. The acquisition included William Hill’s existing U.S. sportsbook operations, mobile app, and retail locations. Caesars immediately rebranded these assets under the Caesars name, launching a new mobile app and digital platform in September 2021. The first physical Caesars Sportsbook opened at Capital One Arena in Washington, D.C., in July 2021 – the first sportsbook ever located inside a U.S. professional sports venue. The parent company, Caesars Entertainment Inc., traces its roots to 1937 when Bill Harrah opened a bingo parlor in Reno, Nevada; the modern corporate entity was formed in 1996 as Eldorado Resorts, which later acquired Caesars Entertainment Corporation in 2020 and adopted the Caesars name. Caesars Sportsbook thus benefits from decades of legacy expertise while operating as a standalone digital brand.

Business Model

Caesars Sportsbook generates revenue primarily through the vig (house edge) on sports wagers, processing millions of bets daily across its digital and retail channels. The platform uses a risk management team and dynamic odds-setting algorithms to ensure profitability. Integration with the Caesars Rewards loyalty program drives cross-sell opportunities, encouraging users to gamble at Caesars casinos, hotels, and other properties. The company also monetizes through in-app advertising and partnerships with sports leagues and media outlets. A key differentiator is the ability to earn Tier Credits and Reward Credits on all bets, which can be redeemed across the entire Caesars ecosystem.

Products & Platforms

The flagship product is the Caesars Sportsbook mobile app, available on iOS and Android, featuring live odds, same-game parlays, prop bets, live streaming, and quick payouts. The desktop website mirrors the app’s functionality. In-person sportsbooks operate at Caesars-owned casinos and partner venues such as Capital One Arena, Westgate Las Vegas, and Rampart Casino. The Caesars Digital Wallet (launched in 2023) provides a unified payment solution across all Caesars platforms. The same-game parlay builder and live betting interface are key features that differentiate the platform from competitors.

Market Position & Competition

Caesars Sportsbook is one of the top five sportsbook operators in the United States by market share, competing directly with DraftKings, FanDuel, BetMGM, and ESPN Bet. Its competitive advantages include the massive Caesars Rewards loyalty network, physical casino presence in Las Vegas and other key markets, and a strong brand heritage. The company holds licenses in over 20 states and has been aggressive in expanding through retail partnerships, such as the recent deal with Westgate Las Vegas. However, it faces intense competition from market leaders DraftKings and FanDuel, which have larger digital footprints and more aggressive promotional spending.

Regulatory & Licensing

Caesars Sportsbook is licensed and regulated in every U.S. state where online sports betting is legal, including New Jersey, Pennsylvania, Michigan, Indiana, Illinois, Virginia, Colorado, Arizona, and more. The platform complies with each state’s gaming commission requirements, including responsible gambling tools and geolocation verification. The regulatory environment has enabled steady expansion, though continued growth depends on further state legalizations.

Recent Developments & News

In December 2025, Caesars announced a new retail sportsbook partnership with Rampart Casino in Summerlin, Nevada. In early 2026, the company expanded its partnership with Westgate Las Vegas Resort & Casino, adding a new sportsbook location. The Caesars Digital Wallet was introduced in 2023, simplifying deposits and withdrawals. Eric Hession was named President of Caesars Digital in July 2024, overseeing the sportsbook’s strategy. The company continues to invest in product improvements and marketing to compete for market share in the increasingly crowded U.S. sports betting market.
