NFL Preseason Data Patterns Emerge from DraftKings Betting Splits

VSiN analyst Steve Makinen examined three full seasons of NFL preseason betting activity on DraftKings between 2023 and 2025, breaking down results by public consensus percentages measured through both handle share and number of individual bets. The review found that when the betting public sided heavily with one side of a point spread, those wagers succeeded at rates between 44 and 46 percent against the spread across the sample period. In contrast, public majorities on game totals posted stronger records, reaching success levels as high as 55 to 64 percent in selected subsets defined by betting volume thresholds. Makinen separated the data into categories based on whether the public exceeded certain percentage thresholds on either side or total, then tracked outcomes using the two distinct metrics of handle percentage and bet count percentage. This dual approach highlighted differences in how large-money bets versus widespread smaller wagers aligned with final results during the preseason window. Observers note that the preseason schedule often features irregular lineups and limited playing time for starters, factors that can alter typical in-season correlations between betting volume and game outcomes. The analysis produced twelve distinct betting systems intended for application during the 2026 preseason. Several of these systems center on fading large public majorities when they appear on point spreads, while others recommend following established totals trends when public betting reaches elevated levels on over or under selections. Each system incorporates filters tied to handle percentages and bet counts to refine entry points, allowing bettors to isolate situations where historical data showed measurable edges.

Breakdown of Public Performance by Category

Data collected from DraftKings revealed consistent underperformance on sides when the public captured more than 60 percent of the handle or bet count. In those instances the side chosen by the majority covered the spread at rates near the lower end of the 44 to 46 percent range. Totals betting presented a different picture, wth certain high-consensus over or under positions exceeding 55 percent success and climbing toward 64 percent when restricted to games that also met minimum volume criteria.

Makinen documented how these splits behaved across home versus away matchups and across different weeks of the preseason schedule. The patterns held after accounting for closing line movement, which often occurs as sharp money enters later in the betting cycle. Researchers at several sports analytics firms have similarly tracked public versus sharp divergence in regular season data, yet the preseason subset examined here offers a narrower but repeatable window for system testing.

Construction of the Twelve Systems

Each of the twelve systems applies specific rules for when to oppose or align with public majorities. Systems focused on sides typically trigger when public handle or bet counts surpass defined thresholds, directing action against the popular side. Totals systems instead identify conditions where public majorities have produced positive historical returns and recommend following those trends under matching volume parameters.

The framework uses both handle share and raw bet count because the two measures sometimes diverge. High handle on one side may reflect a few large wagers, while elevated bet counts often indicate broader recreational participation. Makinen applied these distinctions to create separate rulesets that activate only when both metrics align or when one metric reaches an extreme level. The resulting systems cover a range of scenarios including divisional matchups, interconference games, and contests involving teams with notable roster turnover.

Application Context for 2026

Preseason betting markets open in early August each year, and the 2026 schedule follows the same timeline. Bettors who track opening lines and monitor public percentages through the first two weeks of exhibition play can apply the documented systems as new data accumulates. DraftKings continues to publish updated consensus figures daily, giving users the inputs required to evaluate each rule in real time.

Industry reports from the American Gaming Association indicate that preseason handle remains a smaller but measurable portion of annual sports betting volume, with many operators noting increased mobile activity during exhibition weeks. The twelve systems therefore target a period when line movement can be more pronounced due to lighter overall action and greater uncertainty around player availability.

Conclusion

The three-year dataset compiled from DraftKings provides a factual foundation for the twelve systems Makinen outlined. Public performance on spreads remained below 50 percent when majorities formed, while totals produced stronger results in multiple subsets. Application of the rules during the 2026 preseason will depend on continued availability of the same handle and bet-count metrics that formed the basis of the original analysis.
