The sharpest sportsbooks in 2026, measured on our own data
Updated November 6, 2026 · By the OddsFloor team
Short answer: On NBA player props, Novig has the most accurate number of any book we track. It was right more often than DraftKings, FanDuel, Pinnacle, Caesars, BetMGM, BetRivers, Bovada and ProphetX on 391,679 graded lines. DraftKings is the book the market follows on props. On main lines there's no single leader: DraftKings, Kalshi, Pinnacle and Matchbook lead, and four of the top six are exchanges. bet365 is the book the market ignores.
Why most "sharpest sportsbooks" lists are out of date
Search for the sharpest sportsbooks and you'll get lists from 2023 and 2024. They rank books by opinion or by how much juice they charge. None of them measure whose number is actually right.
Since then the exchanges took off. Kalshi, Polymarket, Novig and ProphetX have far more people betting on them than they did two years ago, and on an exchange other bettors set the price, not a trader. So we measured it. We run oddsfloor.com, a free +EV and arbitrage tool, and we log every book's prices all day.
What "sharp" means here
Sharp can mean two different things, and we tested both.
- Whose number is right. When two books disagree on a line, which one does the result land closer to? This is graded on real results.
- Who moves first. When a book changes its price on its own, does the rest of the market copy it? The book the market follows is the one it trusts.
A book can be one without the other. Novig ends up with the most accurate prop numbers, but it isn't the book that moves first. DraftKings moves first.
Sharpest on player props: whose number is right
We took every 2025-26 NBA player prop line where Novig and another book had different numbers, read one hour before tip, and graded it on the ESPN box score: 391,679 lines over 1,335 games. The score below is where the result landed between the two numbers. 1 means it landed on Novig's number, 0 on the other book's, 0.5 is a tie. Lower means closer to Novig.
| Book | Lines compared with Novig | Score vs Novig | Right more often |
|---|---|---|---|
| DraftKings | 50,581 | 0.66 | Too close to call |
| Pinnacle | 31,025 | 0.73 | Too close to call |
| Caesars | 49,548 | 0.74 | Too close to call |
| BetRivers | 49,883 | 0.80 | Novig, clearly |
| ProphetX | 53,116 | 0.82 | Novig, clearly |
| BetMGM | 45,231 | 0.87 | Novig, clearly |
| Bovada | 61,791 | 0.90 | Novig, clearly |
| FanDuel | 50,504 | 1.01 | Novig, clearly |
Novig was right more often than every book. DraftKings, Pinnacle and Caesars came closest, close enough that we can't call it. FanDuel, Bovada and BetMGM were the furthest off.
Who moves first on player props
For nine straight days, October 28 to November 5, 2026, we logged every pregame price change at every book we track, about 245 million price records. A move counts when a book's price moves a full point on its own and holds, with no other book moving that way in the 10 minutes before. Then we check what the rest of the market did over the next 15 minutes.
| Book | Times it moved first, alone | Market followed | Market went the other way |
|---|---|---|---|
| DraftKings | 18,003 | 44.7% | 6.5% |
| BetUS | 11,598 | 27.5% | 8.8% |
| FanDuel | 13,416 | 27.4% | 9.4% |
| Kalshi exchange | 27,409 | 24.0% | 11.3% |
| Hard Rock | 20,200 | 23.3% | 6.2% |
| Pinnacle | 3,542 | 17.3% | 5.4% |
| Caesars | 4,681 | 15.0% | 8.7% |
| Novig exchange | 77,290 | 15.0% | 8.3% |
| Bovada | 58,007 | 14.2% | 8.4% |
| ProphetX exchange | 45,672 | 13.9% | 9.9% |
| BetRivers | 11,813 | 12.3% | 8.8% |
| Polymarket US exchange | 2,222 | 11.4% | 9.0% |
| BetMGM | 1,781 | 10.1% | 7.0% |
| theScore Bet | 18,780 | 9.7% | 7.6% |
| Betano | 14,925 | 9.0% | 8.1% |
| bet365 | 25,488 | 7.8% | 8.0% |
DraftKings leads by a mile. When it moved a prop on its own, the market went with it 7 times as often as it went the other way, and it was the top book on all nine days. BetUS, FanDuel are next. bet365 sits at the bottom: the market went the other way just as often as it followed. The rest of the time, the market stayed put.

| BetRivers | 1,850 | 7.4% | 5.7% |
| bet365 | 1,810 | 5.4% | 5.7% |
There's no single leader on main lines. DraftKings, Kalshi, Pinnacle and Matchbook are all near the top, and four of the top six are exchanges: Kalshi, Matchbook, Polymarket and Novig. bet365 is last again.
Is Pinnacle still the sharpest sportsbook?
It's still one of them. On NBA props Pinnacle's number was one of the three closest to Novig's. On main lines, when Pinnacle moved first the market went with it 24% of the time and against it only 4%, one of the cleanest records we have. What's changed is that it isn't alone anymore. On props Novig's number was more accurate, and on main lines DraftKings and two exchanges keep pace.
Are exchanges sharper than sportsbooks?
Some are. Novig has the most accurate prop numbers we measured, and on main lines four of the six books the market follows most are exchanges. But being an exchange isn't enough by itself. ProphetX's prop numbers were clearly worse than Novig's, and Kalshi's prop moves got faded more often than most books'.
How to use this
- Price props off the accurate books. On props, Novig's number is the best fair line we have, with DraftKings and Pinnacle close behind. A Novig line that looks +EV against the other books usually isn't. Most of the time the other books are the ones that are off.
- Watch who moves first. When DraftKings and FanDuel both say a slower book's price is too good, betting the slower book beat the closing line 81% of the time over 658 bets. With two or more lead books agreeing it was 80% over 2,841 bets, and it held on every one of the nine days. With none agreeing it was 38%.
- Ignore bet365 moves on their own. The market fades them as often as it follows.
The OddsFloor board prices every line against a fair number built from the sharp books, and we're adding a steam view that shows when the lead books move and which books haven't caught up yet.
Open the free +EV boardHow we measured
- Whose number is right: 2025-26 NBA player props, 1,335 games, lines read one hour before tip, graded on ESPN box scores. Controls planted fake results at Novig's number, at the book's and halfway, and the method landed where it should every time.
- Who moves first: every pregame price change at every book we track, October 28 to November 5, 2026. Controls: the market itself shifted 10 minutes early scored 83%, shifted 10 minutes late scored 13%, and DraftKings shifted earlier scored higher than DraftKings as read, which scored higher than DraftKings shifted later.
- Beat the close: 25,589 +EV bets flagged at sportsbooks over 532 games, graded against a closing line built without the lead books or the book that was bet, so the close can't grade itself.
FAQ
What is the sharpest sportsbook in 2026?
On NBA player props, Novig had the most accurate number of any book we measured: on 391,679 lines where Novig and another book disagreed, Novig was right more often than every one of them, Pinnacle included. DraftKings is the book the rest of the market follows on props. On main lines there's no single leader: DraftKings, Kalshi, Pinnacle and Matchbook lead.
Is Pinnacle still the sharpest sportsbook?
Pinnacle is still one of the sharpest. On NBA props its number was among the three closest to Novig's, too close to call. On main lines, when Pinnacle moved first the market went with it 24% of the time and against it only 4%. It just isn't alone at the top anymore.
Is Novig a sharp book?
Yes. Novig is a betting exchange, so other bettors set its prices. On NBA player props this season its number ended up closer to the box score than every sportsbook we tested. It isn't the book that moves first, though. It's the one that ends up right.
What's the difference between a sharp and a soft sportsbook?
A sharp book's price is hard to beat: its number lands close to what actually happens, and when it moves, the market follows. A soft book's price lags or leans, so its number is the one that's off when books disagree. You find value at soft books and use sharp books to tell you what a line is worth.
Which sportsbook moves its lines first?
On player props, DraftKings. When DraftKings moved a prop on its own, the market followed 7 times as often as it went the other way, and it was the top book on all nine days we tracked. FanDuel and BetUS are next. On main lines DraftKings, Kalshi, Pinnacle and Matchbook lead.
Is bet365 a sharp book?
Not by these tests. bet365 moves first a lot, but on props the market went the other way just as often as it followed (8% vs 8%). A bet365 move on its own tells you almost nothing.
