Pro Exclusive Analysis | Published 10 October 2025 | Olivia Kwan
In fewer than 90 days, the US sports betting industry faces its most significant regulatory disruption since the PASPA repeal. The One Big Beautiful Bill Act’s limitation of gambling loss deductions to 90% of winnings, effective 1 January 2026, initially appeared as a minor technical adjustment. The reality is far more consequential.
This isn’t simply a tax policy change affecting professional gamblers. It’s a structural repricing of sports betting for the industry’s most valuable customers, creating phantom income taxation on break-even bettors and handing a permanent competitive advantage to federally-regulated prediction markets.
Research from American Betting and Venues projects $18-48bn in annual handle could migrate away from state-regulated sportsbooks. High-volume recreational bettors, representing 10% of customers but generating 80% of operator handle, face effective entertainment cost increases of 30-40%. DraftKings and Flutter have seen share prices decline 15%+ as investors recalibrate growth assumptions.
Yet barely three months from implementation, many operators lack concrete retention strategies. This analysis provides the strategic framework operators need to navigate the next 12-18 months, examining which customer segments face genuine tax exposure, modelling revenue impact scenarios, assessing the prediction market competitive threat, and outlining actionable response strategies.
Our central finding: operators cannot price-adjust their way out of this challenge without catastrophic margin compression. The only viable path combines selective retention strategies for highest-value customers, accelerated product diversification toward iGaming, and clear-eyed realism about which markets remain economically viable under the new regime.
