U.S. Online Casino Revenue Soars to Record $905.6 Million in March 2025

This marks a significant 26.2% year-over-year increase, underscoring the sector's robust growth and the expanding appetite for digital gaming experiences.

March Madness Drives Digital Gaming Boom

March has traditionally been a lucrative month for online casinos, coinciding with the NCAA Tournament. The event attracts a vast audience, many of whom are introduced to online casino platforms through cross-promotional efforts with mobile sports wagering.

This strategy has proven effective in converting sports bettors into online casino patrons, contributing to the month's record-breaking revenue.

State-by-State Highlights

All seven states with regulated online casino markets reported remarkable growth:

• Pennsylvania: Approached a staggering $300 million in gross winnings, a feat unimaginable just a year prior.
• Michigan and New Jersey: Both states continued their upward trajectory, setting new monthly records and solidifying their positions as industry leaders.
• Connecticut, Delaware, West Virginia, and Rhode Island: These "Small 4" states collectively contributed to the national surge, each reporting over 20% year-over-year growth and setting their own monthly records.

Tax Revenue Implications

The revenue boom translated into substantial tax benefits for state governments. In March alone, states amassed a combined $177.1 million in tax receipts from $827.6 million in adjusted gross revenue. This represents a $41.1 million increase compared to the same period last year, highlighting the fiscal advantages of regulated online gaming.

Industry Outlook

The March 2025 figures underscore the dynamic growth of the U.S. online casino industry. With technological advancements and strategic marketing efforts, the sector is poised for continued expansion. Analysts anticipate that this momentum will persist, potentially leading to even higher revenue benchmarks in the coming months.
