US Online Casino Data — Market Share By Brand, Gross Gaming Revenue Stats, And Taxation

Last updated: May 14, 2026 | Data current through March 2026 filings

The U.S. regulated online casino market is smaller than sports betting in terms of states (eight, soon to be nine, versus 35+), but it’s larger where it counts: margins. iCasino operators keep roughly 25-30 cents of every dollar wagered, compared to the 10 cents or so that sportsbooks retain. That math, combined with the lack of seasonal volatility, makes iGaming the more attractive business for operators and a significant tax revenue engine for the states that have authorized it.

This page tracks operator market share, state-level gross gaming revenue, and tax generation across the regulated U.S. online casino market. The charts and statistics below are presented by Casino Reports in collaboration with independent analyst Alfonso Straffon, a longtime industry observer, former sports trader, and equities analyst at Deutsche Bank. We update here on or about the third Thursday each month.

🏦 1. iCasino gross gaming revenue by state, LTM (April 2025 through March 2026)

Key Insights:

• Records continue to fall across multiple jurisdictions. Pennsylvania leads the U.S. iCasino market with $3.59 billion in gross gaming revenue over the last 12 months, up from $3.51 billion in the previous LTM frame and $3.42 billion the frame before that. The trajectory has been consistent and upward.
• Michigan and New Jersey closely follow at $3.25 billion and $3.02 billion, respectively. New Jersey has crossed the $3 billion LTM threshold for the first time.
• Connecticut leads the second tier at $742 million, followed by West Virginia at $407 million, Delaware at $150 million, and Rhode Island at $64 million.

Pennsylvania, Michigan, and New Jersey have cemented themselves as the “revenue triad” in U.S. iGaming, each generating over $3 billion in annual GGR. Major operators and suppliers, including Playtech and Evolution Gaming, have established live dealer studios in all three states.

The bigger question is New York. Sen. Joseph Addabbo Jr. introduced iGaming legislation for the fourth consecutive year in January 2026 (SB 2164), with an Assembly counterpart (A6027) from Assemblywoman Carrie Woerner. The proposed 30.5% tax on GGR is well below the 51% sports betting rate but among the highest contemplated nationally for iCasino.

Two obstacles that had previously blocked progress have been cleared: the downstate casino licensing process wrapped in December 2025 (licenses awarded to Bally’s Bronx, Resorts World NYC, and Metropolitan Park), and the state enacted a sweepstakes casino ban. The Hotel and Trades Council remains opposed over job cannibalization concerns, but Addabbo is characterizing 2026 as the clearest path yet. If enacted, New York would instantly become the largest iGaming market in the country by a wide margin, and launch would likely come no earlier than 2027.

In Delaware, the state lottery replaced 888 with Rush Street Interactive at the end of 2023. In September 2024, Rush Street launched live dealer games through Evolution Gaming, available through all three of the state’s licensed casinos.

📊 2. iCasino GGR market share by operator (March 2022 to present)

Key Insights:

• FanDuel Casino set a new record share at 29.4% in November 2025, settling back to 28.4% as of March 2026. In February 2025, FanDuel went live with the exclusive Huff N’ More Puff, a digital version of the wildly popular on-floor slot, which helped accelerate its share growth. FanDuel has also pushed World of Wonka and other exclusive titles throughout the year.
• DraftKings Casino sits at 21.3%, maintaining steady growth. DraftKings has been innovating with a form of peer-to-peer poker available in certain states through its casino app, while also expanding its content library and Golden Nugget Online Gaming and Jackpocket Casino brands.
• BetMGM’s decline is the most notable story in this chart. It surged to 30% share during the post-launch phase in Michigan (January 2021) and has since fallen roughly 12 points to 17.9%. That lost share has gone almost entirely to FanDuel and DraftKings.
• Fanatics Casino at 5.2% has nearly tripled its share from a year ago. Hard Rock has climbed to 3.8%, and the Seminoles are also veering into products resembling iGaming in Florida where they hold a state monopoly.
• Rush Street Interactive (BetRivers/PlaySugarHouse) continues to punch above its weight, stable and rising to 8.7% share. Frequently rumored as an acquisition target, RSI has held at roughly 8-9% for years.

🏛️ 3. iCasino tax revenue by state, LTM (April 2025 through March 2026)

Key Insights:

• Pennsylvania leads with $1.30 billion in iCasino tax revenue over the LTM, driven primarily by its 54% tax rate on online slot machine games. That single rate on slots carries most of the weight; table games and poker are taxed at a far more reasonable 16%.
• Michigan follows at $870 million, benefiting from a graduated tax rate that reaches 28% for the largest operators. Michigan regulators have also been aggressive in pursuing enforcement against unregulated and black market operators, intended to protect both citizens and the state’s licensed operators.
• New Jersey generated $638 million, reflecting the increase from a 17.5% effective rate to 19.75% under Gov. Phil Murphy’s FY 2026 budget (effective July 1, 2025). The full-year impact of the higher rate won’t be visible until the next LTM cycle.
• Connecticut leads smaller states at $114 million, followed by West Virginia ($61 million), Delaware ($50 million), and Rhode Island ($32 million).

This chart, taken together with the GGR figures above, reveals that Michigan and New Jersey remain the most profitable states for operators owing to their more modest tax rates. Pennsylvania’s operators gross the most revenue overall, but the 54% slot tax significantly compresses their margins on that product.

📊 4. Sports betting and iCasino taxes combined, LTM (April 2025 through March 2026)

Key Insights:

• With just seven states having legalized regulated online casinos (Maine’s law is signed but not yet live), those states account for 40% of all gross gaming revenue when combining sports betting and iGaming figures, and 44% of tax dollars collected, reflecting slightly higher effective tax rates on iCasino revenue.
• That is not a typo: New York has nearly matched Pennsylvania ($1.33 billion vs. $1.54 billion) with sports betting tax revenue alone. Pennsylvania’s combined total comes from both iCasino and sports betting. If New York legalizes iGaming at the proposed 30.5% rate, this chart will need a longer x-axis.
• The juxtaposition of the two revenue streams underscores a basic market reality: margins are higher and more stable for online casinos than for sports betting, even in the era of rising structured hold and heavy parlay activity. Sports betting has more states, more handle, and more public attention, but iCasino is the better business.
