Strategies Using NBA DraftKings Betting Splits Data

One of the most touted features on the VSiN.com website, and a feature that we believe to be a fantastic resource for bettors, is the betting splits pages. These are the pages that we have built utilizing the data that DraftKings so graciously provides to us, detailing the breakdowns of the money and ticket splits for point spreads, money lines, and totals. In an article published on the VSiN.com website on opening day, Steve Makinen outlined 14 different systematic strategies for successfully using the DK Betting Splits Data that were developed in the last three seasons. Here are the systems and qualifying plays for today’s games as of 11:30 a.m. ET. These can and will change, so continue to track and qualify the systems up until tip-off for best usage. 

To summarize the findings from the full 2024-25 season, the sample contained 1321 games, and for the most part majority handle bettors were much more successful than majority number of bets groups on point spreads and totals, while both struggled on money lines. The full season performance by the majority handle on totals last year in the NBA was better than any other sport I have covered. In fact, these were the results: 

–  Majority handle on point spreads: 660-614 ATS (51.8%), -15.4 units – ROI: -1.2%
–  Majority number of bets on point spreads: 618-645 ATS (48.9%), -91.5 units – ROI: -7.2%
–  Majority handle on money lines: 842-458 (64.8%). -123.18 units – ROI: -9.5%
–  Majority number of bets on money lines: 886-421 (67.8%). -137.95 units – ROI: -10.6%
–  Majority handle on totals: 708-594 (54.4%). +54.6 units – ROI: +4.2%
–  Majority number of bets on totals: 670-621 (51.9%), -13.1 units – ROI: -1%

DK NBA Betting Splits system #1: When 63% or more of the handle was on the side of a home team playing as a 4-point favorite or less (or as an underdog) on ATS wager, this “super” majority group has gone 170-136 ATS (55.6%) over the last three seasons, good for +20.4 units of profit and an ROI of 6.7%. This is a fairly profitable system that the public seems to get right consistently.  If you see nearly 2/3 of the handle backing a host in an expected competitive NBA game this season, it’s a solid bet to follow it.
System Match (PLAY): NEW ORLEANS

DK NBA Betting Splits system #2: When 59% or more of the handle has been on the road side of an ATS wager, this “super” majority group has gone 748-665 ATS (52.9%) over the last three seasons. This has produced a profit of +16.5 units and an ROI of 1.2%. This has been a very consistent system since I first found it, and for its simplicity, fairly successful. Remember, handle is the total amount of money on a game. When a good portion of the overall money is on a road team in the NBA, it wins more often than not.
System Match (PLAY): ORLANDO 

DK NBA Betting Splits system #3: It is a somewhat rare situation but when there was a majority handle backing a home underdog in the NBA over the last three seasons, that group produced a 94-70 ATS record (57.3%).  This has netted +17 units and an ROI of 10.4%. As a general rule, most bettors tend to bet favorites. This lot of 164 games was only about 4.0% of the total sample size.
System Match (PLAY): TORONTO 

DK NBA Betting Splits system #4: In another somewhat rare situation, when there was a majority handle backing the team with fewer wins on the season in the NBA over the last 2+ seasons, that group produced a 352-298 ATS record (54.2%), good for +24.2 units of profit and an ROI of 3.7%. This lot of 650 games was only around 20% of the total sample size.
System Matches (PLAY ALL): HOUSTON, GOLDEN STATE 

DK NBA Betting Splits system #6: In NBA non-Conference games (East versus West) of the last three seasons, DK super majority handle groups of 62% or greater have been successful, as they are 395-348 ATS (53.2%). If you consider that the overall majority numbers showed a 51.2% success rate, they were about 2% improved on these more-rare contests. This simple angle has produced +12.2 units of profit and an ROI of 1.6%.
System Matches (SLIGHT PLAY ALL): NEW ORLEANS, MEMPHIS, ORLANDO 

DK NBA Betting Splits system #8: Naturally, with super majority handles doing well on non-conference and non-divisional conference games as compared to the overall, the area where these groups would figure to struggle would be in divisional games. The super-majority number is a little higher, however, 67% in fact. When this super-majority number has backed a team in divisional games over the last three seasons, they are just 137-153 ATS, good for 47.2%. This is over a 4% drop off compared to the overall majority figures and has resulted in -31.3 units of loss and an ROI of -10.8%.
System Match (FADE): GOLDEN STATE 

DK NBA Betting Splits system #11: One of the best, simplest, and most frequent angles I have been able to uncover is when a majority of handle bettors were backing the Under in a NBA game. It is generally believed that most NBA bettors prefer taking Overs. When any majority number have favored the Under option over the last three seasons, the results have been strong, with Under the total on these games going 434-351, good for 55.3%, +47.9 units, and an ROI of +6.1% since January ’23.
System Matches (PLAY UNDER ALL): WSH-MEM, PHX-GSW, POR-SAC 

DK NBA Betting Splits system #12: There has been some decent success for number of bets majorities when they don’t get too heavily invested. In fact, majorities on either side of the total (Over or Under) of 57% or less have gone 346-301 (53.5%) for +14.9 units and an ROI of +2.3% since January 2023.
System Match (SLIGHT PLAY): OVER – ORL-UTA, POR-SAC 

DK NBA Betting Splits system #14: Majority handle Under bettors have been successful when sticking to their guns despite DraftKings raising total off of its opening number. These Under majorities have gone 176-126 (58.3%) since January 2023 by not getting baited into this totals trap. This has been the most profitable angle of all in terms of ROI, producing +37.4 units of profit for 12.4%.
System Match (PLAY UNDER): POR-SAC
