💡 Props are the new frontier: Player prop markets showed the most pricing inefficiency in 2025, with same-game parlay boosts creating calculable EV opportunities on nearly every major game.
Several major operators shifted from bonus bet offers toward profit boosts and odds enhancements in late 2025. These require different calculation strategies — understanding the true EV and max cap is essential.
SGP insurance and boost promos grew 34% YoY. These are high-complexity promos that reward calculated decision-making over intuitive picks.
Missouri and Vermont legalized in 2024–2025. Historically, the first 6–18 months after a state goes live have the highest promotional value as operators acquire customers aggressively.
Average account lifespan for active promo hunters has decreased to ~12 months at DraftKings and FanDuel. Multi-book strategy is no longer optional — 7+ active books is the new baseline for serious grinders.
BetRivers and WynnBET consistently offer the most generous reload deposit matches — an underutilized category by casual bettors focused only on the major books.
