The U.S. online casino sector is closing 2025 on a note of consolidation and regulatory change, with major operators reporting stronger-than-expected results, states locking in record tax receipts from iGaming, and federal tax reporting rules set to alter how casual players and operators handle smaller wins come January 1, 2026.
Operators report momentum as competition intensifies
BetMGM, the joint venture between Entain and MGM Resorts, and other large operators have reported robust growth through 2025, driven by stronger iGaming performance and a rebound in online sports betting. In a business update for the first quarter of 2025, BetMGM said net revenue jumped 34% year-over-year, with iGaming up 27% and online sports up 68%, and that the company was on track for positive EBITDA for the full year. “2025 is off to an encouraging start,” BetMGM CEO Adam Greenblatt said in the company statement, pointing to product improvements and refined player management as key drivers.

That corporate momentum has encouraged further investment and marketing spend across the industry, escalating competition in the major regulated markets – notably Pennsylvania, Michigan and New Jersey – where state-regulated iGaming continues to deliver record receipts and rising monthly win totals throughout 2024 and into 2025.
Regulation, state revenues and the black market
State-level iGaming tax take has become a central political talking point. Several states reported all-time highs in online gambling revenue for 2024 and into 2025, prompting lawmakers to debate tax rates, consumer protections and licensing guardrails. Industry groups warn that higher betting taxes can push players toward unregulated platforms, a trend regulators are watching as they balance revenue needs with consumer safety.
At the same time, enforcement against offshore and unlicensed operators has increased in some jurisdictions but remains uneven. Regulators and the industry have emphasized strengthened age verification, anti-money-laundering measures and responsible gambling tools as priorities for 2026 licensing rounds.
Tax reporting changes and what players should expect
A consequential federal change due to take effect January 1, 2026 will raise the IRS slot machine jackpot reporting threshold – a move that will affect how small jackpots and slot wins are reported and taxed. Industry observers say the shift will reduce administrative burdens for occasional players while prompting operators and tax professionals to update reporting and withholding processes ahead of the new year.
What to watch next
The immediate months ahead will be defined by how operators translate 2025 momentum into sustainable margins amid intensifying competition, how states respond to the dual pressures of maximizing tax revenue while curbing the black market, and how firms operationalize upcoming federal tax changes before they take effect on January 1, 2026. Regulators’ decisions on licensing, advertising limits and consumer safeguards in early 2026 will also shape whether the rapid growth of recent years stabilizes or accelerates into new markets.
