Excessive margin in online betting puts gaming volume at risk
In the sports betting industry, there's a maxim that operators seem to be forcibly rediscovering: the inverse relationship between turnover (volume wagered) and hold (retention margin). The premise is simple but powerful: the more money sportsbooks retain today, the less capital users have to keep playing tomorrow. This phenomenon has begun to be reflected in the financial reports of industry giants, where the growth of betting volume has notably slowed after seasons of historically high margins.
Flutter (FanDuel) revealed in its Q4 2025 report that its turnover growth fell to 3%, a figure well below market expectations. During the NFL season, the operator achieved a 19% hold, a robust figure for its books but one that seems to have depleted the liquidity of its user base. As a consequence, Flutter's shares suffered an 18.8% drop, trading below USD 100 for the first time since its New York Stock Exchange debut in 2024.
The Exhaustion of the Same Game Parlay Model
For quarters, operators have pushed Same Game Parlays (SGPs) as the flagship product to sustain growth amidst the stagnation of new state market openings. However, industry analysts suggest that the industry may have reached "peak SGP." Experts like Davis Catlin of Discerning Capital argue that a retention margin approaching 20% is not sustainable in any gaming modality and that the ecosystem needs to operate at levels closer to 12% or 14% to maintain long-term player engagement.
This situation is replicated at DraftKings, where volume growth slowed to 4% in January after retaining 16% of the money wagered during the American football season. Pressure on the consumer's pocket doesn't just come from the house's margins; inflation and competition from prediction markets and exchange houses are fragmenting bettors' attention and capital, who now have multiple avenues to manage their risk.
Seeking the Balance Between Profit and Retention
To reverse this trend, some operators are evaluating adjusting their "generosity strategy." This implies returning a larger portion of the margin through bonuses and promotions that keep users active and with balances in their accounts. The challenge for sportsbooks in 2026 will be to find the right point of profitability that doesn't "kill the goose that lays the golden eggs," ensuring that the customer feels they still have a real chance to win.
