Cowboys vs Texans Same Game Parlay: Williams Held Under 70
By Jake Hari
October 4, 2026

Houston hasn't won a game yet and it's still the favorite at home against Dallas. I think the Texans get there, but I think it's close, and a close game changes which legs belong on a same game parlay.
So I picked the score before the legs. I typed a narrow Houston win into the free Kalshi Parlay Simulator, then flipped it for the Dallas upset, and kept the top three-leg combo for each.
Houston By Three
Dallas Cowboys (1-2) at Houston Texans (0-3) Sunday, October 4 · 1:00 p.m. ET · Reliant Stadium · FOX Stokastic Sims: Texans win 53%
Neither team has a starter on the injury report. I think this one comes down to the last possession.
Williams Stays Quiet

| Leg | Side | Kalshi |
|---|---|---|
| DAL wins by 6+ | NO | 75¢ (-300) |
| Over 53.5 total points | NO | 64¢ (-178) |
| Javonte Williams 70+ rushing yards | NO | 64¢ (-178) |
| Sims price | Kalshi legs | Near HOU 26-23 |
|---|---|---|
| 37.8¢ (+165) | 30.7¢ (+226) | 65% |
The Sims Price is how often the whole combo hit in 10,000 sims. Kalshi is the three legs bought one at a time, multiplied. Current Script is how often it hit in the sims that finished near my score.
These legs hang together: when Dallas can't get Williams going, it doesn't pull away, and the game doesn't get to a shootout. The sims price beats the leg-by-leg price, and if the game lands near my score this cashes more often than not.
Not every card for this score is worth it. The third card adds YES on Dak Prescott 2+ passing TDs, and its Kalshi number is higher than its Sims Price. I'd skip it.
Dallas Flips It

| Leg | Side | Kalshi |
|---|---|---|
| HOU wins by 6+ | NO | 62¢ (-163) |
| Over 41.5 total points | YES | 71¢ (-245) |
| David Montgomery 60+ rushing yards | NO | 70¢ (-233) |
| Sims price | Kalshi legs | Near DAL 26-23 |
|---|---|---|
| 33.0¢ (+203) | 30.8¢ (+225) | 74% |
Houston doesn't run away with it in the games where Montgomery is held down, and this ticket doesn't need Dallas to win. It cashes in a narrow Texans win too, which is why I like it.
