Top 5 U.S. States With the Highest iGaming Revenue
Over the past few years, the U.S. iGaming industry has experienced significant growth in popularity and profitability. With more states legalising online casinos, poker, and sportsbooks, iGaming revenue continues to climb year after year.
In this detailed article, we’ll explore the top five U.S. states with the highest iGaming revenue in 2025, based on the latest available data.
What Drives iGaming Revenue in the U.S.?
Before diving into the rankings, it’s essential to understand what fuels the iGaming revenue. This includes:
- Legalisation and Regulation: States with well-defined legal frameworks attract more operators and customers.
- Population Size: Bigger markets naturally have more potential players.
- Product Diversity: Platforms offering a mix of different casino games and sports betting perform better.
- Brand Presence: Renowned operators like BetMGM and FanDuel that offer seamless mobile and desktop experiences boost engagement.
- Marketing and Promotions: Loyalty programs and first-time user bonuses help retain customers.
1st Place: New Jersey
New Jersey was the pioneer of legal iGaming in the U.S., launching online casinos and poker as early as 2013. Over a decade later, it still dominates the market, with Atlantic City casinos expanding their reach through digital platforms.
Total iGaming Revenue (2025 estimate): $1.9 billion+
Why New Jersey Leads:
- Offers a full range of iGaming products: slots, poker, live dealer, and sports betting.
- Partnerships with global brands like BetMGM, Borgata, and Caesars.
- Strong tech infrastructure and aggressive marketing.
BetMGM remains a strong contender in New Jersey’s regulated iGaming market, offering players a wide selection of slot games online, reliable mobile access, and integrated rewards through its M life loyalty program, while also competing in a crowded landscape alongside other licensed operators like Caesars, DraftKings, and FanDuel.
2nd Place: Michigan
Michigan has seen rapid growth since legalizing online casinos and poker in early 2021. Today, it is known as the second-largest iGaming state by revenue, thanks to its broad player base and strong operator competition.
Total iGaming Revenue (2025 estimate): $1.75 billion+
What Sets Michigan Apart:
- Early-mover advantage in the Midwest.
- A diverse demographic of online players.
- Operators are fiercely competing for market share.
Michigan’s robust regulation also gives players confidence in fair play and secure payouts.
3rd Place: Pennsylvania
The Pennsylvania Gaming Control Board legalized online gambling in 2017. This was the cause of a high gaming population of nearly 13 million and the start of a strong gambling culture. Pennsylvania is now known as a heavyweight in the iGaming arena. Online slots and table games are especially popular, and state taxes on iGaming revenue generate hundreds of millions each year.
Total iGaming Revenue (2025 estimate): $1.6 billion+
Pennsylvania’s Key Highlights:
- High consumer trust due to the state’s strict regulatory oversight.
- Comprehensive gambling offerings.
- Continuous growth in mobile gambling adoption.
Pennsylvania’s regulated iGaming market gives players access to licensed platforms offering a wide variety of online slots and table games, with operators required to meet strict standards for security, fairness, and responsible gambling.
4th Place: West Virginia
West Virginia rounds out the top five, thanks to its progressive approach to online casino legislation and its partnerships with major operators. Despite a smaller population, the state punches above its weight due to strong user adoption and operator competition.
Total iGaming Revenue (2025 estimate): ~$150 million
West Virginia Standout Features:
- Home to platforms like BetMGM, FanDuel, and BetRivers.
- Focus on quality content, especially in online slots and blackjack.
- Quick expansion of mobile-friendly gaming options.
In West Virginia, online slot games are the most popular vertical. There are top-ranking casino sites that offer frequent bonus rounds, high return to player (RTP) games, and seasonal promotions.
5th Place: Delaware
While smaller in population and total revenue, Delaware deserves a place on this list due to its early adoption and consistent year-over-year growth in iGaming. It was among the first three states to legalize online gambling back in 2013.
Total iGaming Revenue (2025 estimate): ~$40 million
What Makes Delaware Unique:
- One of the first movers in U.S. iGaming history.
- State-run iGaming through the Delaware Lottery.
- Strong performance in online poker and classic table games.
While Delaware’s numbers don’t match the billions of New Jersey or Pennsylvania, its regulated model and compact agreements with Nevada and New Jersey for poker liquidity are helping it stay relevant in the national conversation.
Other States on the Rise
While the top five U.S. states currently dominate the iGaming scene, there are several other states that are rapidly growing. This includes:
- Connecticut: Recent legislative changes are opening the door to larger operators.
- Nevada: Still primarily focused on poker and sports betting, but could expand online casino offerings.
- Rhode Island: Legalized iGaming in 2023 and is seeing moderate uptake.
Our Final Say
The U.S. iGaming market is not just growing, it’s thriving. States like New Jersey, Michigan, and Pennsylvania have built gold standards for online gambling regulation and player satisfaction.
Smaller states like West Virginia and Delaware have shown that smart legislation and strong operator partnerships can also deliver impressive results.
As more states open up to iGaming in 2025 and beyond, this landscape will only become more competitive and more rewarding for U.S. players.
