FanDuel started in 2009 as a daily fantasy sports company. In 2018 it launched its sportsbook and grew it into the biggest name in regulated US betting. It’s owned by Flutter Entertainment, the world’s largest online gambling company, which is listed on the New York Stock Exchange.
FanDuel is the #1 sportsbook in the US, with 39% of online sports betting revenue, and the #1 online casino by revenue share. It’s fully licensed and regulated in every state it operates in. That means player funds are protected, games are independently tested and disputes can go to a state regulator. Beyond the sportsbook and casino, FanDuel also runs horse racing (FanDuel Racing and TVG), daily fantasy and its own TV network.
What stands out
FanDuel’s app is the benchmark for mobile betting. It’s fast, easy to use and rated 4.8/5 on iOS from over 2.2 million reviews. It leads on same-game parlays, with a Parlay Hub of ready-made bets, alongside live betting, live streaming, daily profit boosts and injury protection through BetProtect+. New for 2026 are the FanDuel Rewards Club for sports bettors and an AI betting assistant, AceAI.
New sports bettors can bet $5 a day for five days and get $50 in bonus bets each day, win or lose, for $250 in total. On the casino side, players in MI, NJ, PA and WV get 1,000 bonus spins and a $25 casino bonus from a $5 deposit, with only a 1x playthrough.
The casino has 1,800+ games from IGT, NetEnt, Red Tiger and Games Global, plus FanDuel exclusives. Its live dealer lobby is powered by Evolution. Payouts are among the fastest in the industry: PayPal, Venmo, Play+ and debit card withdrawals typically clear within 24 hours, and there are no fees.
Worth knowing before you sign up
FanDuel is only available where online sports betting or casino gaming is legal, so availability depends on your state. Online casino is limited to a handful of states. The welcome offer requires a bet on five straight days to unlock the full $250, and bonus bets expire after 7 days. Profit boosts are usually capped at a $50 stake, and early cash-out isn’t available on every market. Support runs through live chat and email, with no phone line. As at most major sportsbooks, winning bettors can see their stake limits reduced.
The verdict
FanDuel sets the standard for regulated US sports betting. It has the best app in the market, deep same-game parlay tools, fast payouts and the security of full state licensing. It’s the first account most US bettors should open, and a strong casino choice in states where online casino is legal.
