Pennsylvania finished 2025 as the largest US online casino market for the second consecutive year, posting $3.46 billion in gross gaming revenue compared to New Jersey's $2.91 billion. The 19% revenue gap between the two East Coast iGaming markets has widened from just $80 million in 2023 and reflects the structural advantages Pennsylvania's regulatory framework and operator licensing have created for sustained growth.
Quick answer: Pennsylvania posted $3.46 billion in 2025 online casino gross gaming revenue versus New Jersey's $2.91 billion, a 19% gap. Pennsylvania benefits from larger population, friendlier per-operator tax structure for retail-linked iGaming, and a maturing slot vertical that delivered 76% of its annual GGR. Michigan ($3.1 billion) sits between the two as the third major regulated iGaming market.
How Pennsylvania Pulled Ahead
Pennsylvania's regulated iGaming market launched in July 2019, almost six years after New Jersey debuted online casino gaming in November 2013. Despite the late start, Pennsylvania caught and passed New Jersey in monthly revenue by Q3 2024 and never looked back. Several factors drove the reversal:
- Population advantage — Pennsylvania's 13 million residents versus New Jersey's 9.3 million
- Operator competition — 15 licensed iGaming brands operating in Pennsylvania versus 9 in New Jersey by year-end 2025
- Retail-linked operator strategy — Pennsylvania's casino partnership requirement aligned operator economics
- Slot game volume — Pennsylvania players favor online slots (76% of GGR) more than New Jersey players (68%)
The 2025 result placed Pennsylvania ahead by a wider margin than any year since the markets coexisted, and 2026 monthly numbers through April suggest the gap will continue widening this year.
Operator Market Share Breakdown
The competitive landscape in each state looks slightly different. In Pennsylvania, top performers in 2025 include:
- FanDuel Casino — approximately 24% market share
- DraftKings Casino — 21%
- BetMGM Casino — 14%
- Hollywood Casino (Penn Entertainment) — 11%
- Caesars Casino — 8%
- Combined remaining operators — 22%
New Jersey's market is more concentrated at the top:
- FanDuel Casino — 28% market share
- DraftKings Casino — 23%
- BetMGM Casino — 16%
- Borgata Online — 10%
- Caesars Casino — 7%
- Combined remaining operators — 16%
Notably, the top three operators in both states are identical, reflecting the duopoly-plus-one structure of US iGaming. FanDuel Casino's leadership in both markets demonstrates how its cross-product audience — sports betting customers cross-selling into casino — drives the strongest organic growth in the category.
Tax Treatment and Regulatory Differences
One key driver of Pennsylvania's advantage is the structure of its tax code. Pennsylvania taxes online slot revenue at 54%, online table games at 16%, and online poker at 16%. New Jersey imposes a flat 17.5% effective rate (15% gaming tax plus 2.5% Casino Reinvestment Development Authority fee).
While Pennsylvania's nominal tax rate on slots is far higher, the state's structure of crediting promotional play deductions, allowing aggressive bonus offers, and connecting retail brick-and-mortar partnerships has translated to faster operator scale-up. New Jersey's lower tax rate has not translated into proportionally higher operator margin growth, partly because the market is more saturated and player acquisition costs run higher.
Player Behavior and Game Mix
The two markets exhibit different player preferences:
- Slot dominance — Pennsylvania players play slots at higher per-capita rates, generating 76% of GGR versus 68% in New Jersey
- Live dealer growth — Both states grew live dealer revenue by over 30% in 2025, but New Jersey's live mix is slightly higher at 16% versus Pennsylvania's 12%
- Online poker — Pennsylvania benefits from MSIGA pool sharing since April 2025, while New Jersey's online poker remains stagnant
- Mobile penetration — Both states see 91-93% of total iGaming session volume on mobile devices in 2026
Bonus and Promotional Activity
Pennsylvania operators offer slightly more aggressive welcome promotions on average. Top promotional structures across the state include:
- FanDuel Casino — Up to $1,000 in casino bonus + $20 in free play
- DraftKings Casino — $50 free play + 100% match up to $2,000
- BetMGM Casino — $25 in free play + 100% match up to $1,000
- Hollywood Casino — $510 in free play across initial deposits

Looking Ahead to 2026 Numbers
The momentum continues into 2026. Pennsylvania April 2026 monthly revenue hit $245 million (per data from top online casinos tracking). New Jersey April 2026 came in at $263 million, but Pennsylvania's twelve-month rolling total has grown faster, projecting an annual finish near $3.9 billion compared to New Jersey's projected $3.3 billion.
Michigan ($3.1 billion in 2025) is positioned to overtake New Jersey in 2026 if current monthly growth rates hold. The state's combination of slot dominance, FanDuel-DraftKings duopoly maturity, and limited operator competition has accelerated maturation. Other regulated states — West Virginia, Connecticut, Rhode Island, Delaware — operate at smaller scale relative to the Big Three.
What This Means for Players
For players in either state, the operator competition translates directly into:
- Larger welcome bonuses and reload promotions
- More game variety as providers push exclusives
- Tighter retention loyalty programs as operators fight churn
- Faster game refresh cycles with new slots and live dealer tables
The competitive dynamics also reduce risk for new players: if one operator delivers poor service or limits player accounts unfairly, multiple alternatives exist within the same state.
