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 the game as of 12:30 p.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 first half data of the 2025-26 season, the sample contained 633 games, and for the most part, majority bettors have lost on all six point spread, money line, & total categories. In fact, this has been the worst half-season they have endured since I started studying this subject a few years ago. Here are the results:

– Majority handle on point spreads: 291-335 ATS (46.5%), -77.5 units – ROI: -12.4%
– Majority number of bets on point spreads: 287-323 ATS (47%), -68.3 units – ROI: -11.2%
– Majority handle on money lines: 379-247 (60.5%). -123.2 units – ROI: -20.2%
– Majority number of bets on money lines: 404-227 (64%). -113.7 units – ROI: -18%
– Majority handle on totals: 306-310 (49.7%). -35 units – ROI: -5.7%
– Majority number of bets on totals: 307-318 (49.1%), -42.8 units – ROI: -6.8%

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 211-174 ATS (54.8%) over the last 3+ seasons, good for +19.6 units of profit and a ROI of 5.1%. 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): SAN ANTONIO (-3.5 vs OKC)

DK NBA Betting Splits system #4: In another somewhat rare situation, but when there was a majority handle backing the team with fewer wins on the season in the NBA over the last 3+ seasons, that group produced a 456-412 ATS record (52.5%), good for +2.8 units of profit and an ROI of 0.3%. This is another system that has dropped a bit this season but has still outperformed the normal levels by a decent amount. We’ll see if it can stay positive in the second half of the season.
System Match (SLIGHT PLAY): SAN ANTONIO (-3.5 vs OKC)

DK NBA Betting Splits system #7: The number 63% or higher has been a key super-majority number in non-divisional conference games over the last 3+ seasons, with handle groups of that size boasting a 579-508 ATS record, good for 54.2%. This is over a 4% improvement on the overall majority figures and has netted +20.2 units of profit and a ROI of 1.9%.
System Match (PLAY): SAN ANTONIO (-3.5 vs OKC)

DK NBA Betting Splits system #10: Majority handle money line wagerers have struggled in each of the last three playoff seasons, with handle majorities going 149-110 for -44.87 units and an ROI of -18%. Compare this to the usual ML return of just over -5%, and you can see bettors are losing on a lot of favorite plays.
System Match (FADE): SAN ANTONIO ML (-155 vs OKC)

DK NBA Betting Splits system #13: The average NBA game total since January of 2023 has been a bit more than 228. In NBA games with “low” totals, or those less than 220, majority handle bettors have gone an impressive 408-345 (54.2%), while majority number of bets groups are a bit less at 398-359 (52.6%). Both groups have proven profitable regardless of which side of the total they have chosen.
System Match (PLAY OVER): OKC-SAS (o/u at 218.5)
