2026 NASCAR Cup Series

Ten races to the finish, and the odds are shifting.

Championship win probabilities for every mathematically live driver, recalculated after each race from stage points, race points, and what's left on the schedule. Not a sportsbook line — this is what the model says a fair bet would look like.

Fair-value odds against winning — not a sportsbook line

True Odds convert each driver's championship win probability into fair-value odds against — (1 − p) / p — with no house edge (or vig) built in. A driver at 1.75 to 1 would need to win better than 36% of the time for the bet to break even.

Pick two drivers and set how many points per race each one averages for the rest of the Chase. Everyone else keeps scoring what they have averaged in the Chase so far. See who would win the title, where everyone would finish, and how soon each driver would be out of it.

How this is calculated

Each driver's score in a race is built from three pieces: Stage 1 points, Stage 2 points, and race finish points. The model treats each of those as a random draw across the field, then works out the full range of outcomes for the races still left on the schedule by combining that distribution with itself once per remaining race.

A driver's championship win probability is the chance their season-ending total ends up higher than everyone else's, given those simulated outcomes. Two field sizes are shown side by side — 36 cars and 37 — since that one assumption has enough sensitivity to matter.

The model treats every driver as equally capable and every remaining race as statistically identical. That's a simplification: it doesn't account for a driver's actual form, or for track-specific strengths and weaknesses like superspeedway variance. Only drivers still mathematically able to catch the leader are shown.
