Player props are eating an increasingly large share of US sports-wagering handle, and the growth curve is accelerating, not flattening. Through the first half of 2026, props account for 36% of total US handle across all sports — up from 31% a year ago and 24% three years ago. Three forces are driving the shift, and understanding them matters for any bettor planning their second-half betting strategy.
What's behind the growth
First, product. Every major operator has expanded its prop menus aggressively — more players covered, more stat categories, more alt lines per player. Same Game Parlay product on props has gotten dramatically better, and SGP volume has tripled in two years across most operators. Second, market mix. Sports with high prop volume relative to side volume — MLB, WNBA, golf, UFC — are taking a bigger share of total handle than they did three years ago. Third, behavioral. Bettors who started on sides are increasingly graduating to props as their preferred market once they've learned the basics.
Sport-by-sport prop volume
MLB player props are the single largest growth category of 2026 so far — handle is up sharply, partly because the prop menus are deeper, partly because the underlying skill of bettors has improved. NBA props remain the largest single sport for prop handle on an annualized basis (the season takes most of the year), and the depth of the NBA prop board is unmatched. WNBA props have been the breakout category of the summer. Golf and UFC props continue to grow steadily.
The hold-rate question
Books make more money per dollar of prop handle than they do per dollar of side handle. Hold rates on individual props typically run 7-12% — meaningfully higher than the 4.5% standard on sides — and parlay props can compound to 15-25% hold. That's why operators love the prop product. For bettors, it means the bar for profitability on props is higher: you need a 4-7% edge over fair value just to break even after juice, depending on the market.
Where the sharp edges live
Three habits separate prop bettors who profit from those who don't. First, line-shop every prop — pricing variation between operators is larger on props than on any other market type. Second, bet the lines that haven't moved when news has — late-day prop pricing often lags injury, rest and lineup news by hours. Third, treat props as projection-driven, not narrative-driven. Bettors who decide what they want to bet before they look at the number are not betting; they're spending. Our expected value calculator handles the projection-to-number math.
Operator menu depth
DraftKings currently has the deepest prop menu across the major sports — for any starter, the over/under board typically covers 6-10 individual props. FanDuel has the cleanest UX and the best-priced SGP product. BetMGM frequently sits on the best individual prop price of the day. For most disciplined prop bettors, three or four accounts open is the right setup.
What to watch in the second half
The two structural trends to monitor are SGP pricing transparency (regulators are pushing for clearer disclosure of SGP hold) and prop limits (operators are getting more aggressive at limiting sharp prop accounts). Neither changes the strategy for recreational and serious bettors, but both will reshape the market in the next 12-18 months.
