Ryan Sieg won the Winn-Dixie 250 Powered by Coca-Cola at Daytona International Speedway on Friday, August 28, in overtime over Austin Hill. It was his first NASCAR O'Reilly Auto Parts Series win in 424 starts, per Speedway Media's race report, after five runner-up finishes without one. Kalshi's last trade on him before the green flag was 3 cents. Hill, the favorite this page spent August arguing against, finished second.
The Board: Winn-Dixie 250 Pre-Race Prices, Graded
Kalshi's winner market is settled. Kalshi listed a contract on all 39 entered drivers, and the 15 that carried the story are below with the last trade before the green flag, the afternoon midpoint this page published on August 28, the median of the seven price-blind model seats, and where each driver finished. The panel numbers are exactly as they were scored that day. Dawson Cram failed to qualify and is not shown.
| Driver | Team | Last pre-race print | Afternoon midpoint (Aug. 28) | AI panel (median) | Finished | Settled |
|---|---|---|---|---|---|---|
| Austin Hill | Richard Childress Racing | 23¢ | 18.5¢ | 9.5% | 2nd | No |
| Jesse Love | Richard Childress Racing | 15¢ | 11.5¢ | 9.2% | 20th | No |
| Justin Allgaier | JR Motorsports | 10¢ | 9.0¢ | 12.5% | 6th | No |
| Sam Mayer | Haas Factory Team | 9¢ | 5.5¢ | 4.0% | 25th | No |
| Carson Kvapil | JR Motorsports | 8¢ | 7.0¢ | 7.5% | 3rd | No |
| Sheldon Creed | Haas Factory Team | 8¢ | 6.5¢ | 7.3% | 10th | No |
| Rajah Caruth | JR Motorsports | 8¢ | 5.5¢ | 2.8% | 32nd | No |
| Corey Day | Hendrick Motorsports | 6¢ | 2.5¢ | 5.1% | 29th | No |
| Sammy Smith | JR Motorsports | 6¢ | 6.0¢ | 5.0% | 36th | No |
| Brent Crews | Joe Gibbs Racing | 4¢ | 2.5¢ | 3.0% | 35th | No |
| Taylor Gray | Joe Gibbs Racing | 4¢ | 4.5¢ | 2.6% | 26th | No |
| Harrison Burton | Sam Hunt Racing | 4¢ | 0.5¢ | 1.3% | 8th | No |
| Ryan Sieg | RSS Racing | 3¢ | 2.0¢ | 3.6% | 1st | Yes |
| William Sawalich | Joe Gibbs Racing | 3¢ | 2.0¢ | 3.3% | 37th | No |
| Jeremy Clements | Jeremy Clements Racing | 2¢ | 1.5¢ | 2.3% | 33rd | No |
Sieg's contract traded between 2 and 3 cents all afternoon and settled yes. The panel's median on him was 3.6%, above both the midpoint the seats never saw and the last pre-race print.
A number that size means he wins about one race in 28, so one result proves nothing about a method. What it does show is that seven models handed a ledger with no prices in it all put the same driver near the bottom of the board above the market, and the market was wrong in the direction they said.
The 24 contracts not shown all settled no, and none of those drivers finished better than fourth. Every row is graded against the real settlement on the full graded scoreboard, which is recomputed daily.
How Ryan Sieg Won From Twelfth On The Grid
Sieg qualified twelfth, behind pole-sitter Rajah Caruth, with Hill eighth and Allgaier eighteenth.
Per NASCAR.com's recap, a late pit stop got him inside the top five, and he was running fourth when a caution in the closing laps forced a two-lap overtime. He restarted behind the JR Motorsports pair of Carson Kvapil and Justin Allgaier, used a push from Hill to draw alongside Kvapil, cleared both by the white flag, and led the final two laps. Hill crossed 0.149 seconds behind him, with Kvapil third.
"This is incredible," Sieg told reporters afterward, per Speedway Media, "to do it right now in the way we did it, that's amazing."
Sieg's previous best in this series was second, five times, driving for RSS Racing, the family team, against the four-car JR Motorsports and Joe Gibbs blocs. He had been mathematically eliminated from the Chase before the cars rolled off, which made him the one driver near the cut with nothing to protect while everyone around him was counting points. Friday night, that was the winner's profile.
What Happened To Austin Hill, The Favorite
The case this page built against Hill was the August split: four February wins at Daytona, no top-ten in four August starts here. The panel's median put him at 9.5% against an 18.5-cent midpoint, the largest gap on the board.
His night: 22 laps led, the first stage won, second at the line, his first August top-ten here in five tries.
The market paid for a driver who would be in the picture at the finish and got that. On a market that pays only the winner, the panel's lower number was closer. Whether four August starts were a pattern or a small sample is still open, and a fifth data point that reads second does not close it.
Justin Allgaier, The Panel's Favorite, Finished Sixth
Every seat made Allgaier its favorite, at a 12.5% median against a 9-cent midpoint. He started eighteenth, ran near the front in both stages, restarted the overtime on the front row, and came home sixth.
The structure the panel priced was all there: JR Motorsports cars led 61 of 105 laps and held the front row for the restart that decided it. What the alliance could not do was stop a single RSS Racing car with a push from Hill. By Speedway Media's account, the overtime caution came from Allgaier's contact with his own teammate Caruth.
The Chase Field: Caruth In By Five, Two Gibbs Cars Out
NASCAR scrapped its elimination playoff for 2026 and went back to the Chase: the top 12 in points after Daytona advance to a nine-race postseason that opens at Darlington on September 5. With win-and-you're-in gone, Sieg's trophy did not come with a postseason. Six drivers were racing for four seats.
| Driver | Pre-race margin | Finished | Result |
|---|---|---|---|
| Parker Retzlaff | 45 clear | 14th | In, ninth seed |
| Sam Mayer | 18 clear | 25th | In, tenth seed |
| Taylor Gray | 1 outside | 26th | In, eleventh seed |
| Rajah Caruth | 15 outside | 32nd, pole, stage 2 win | In, twelfth seed, by five points |
| William Sawalich | Held eleventh | 37th, accident, lap 44 | Out |
| Brent Crews | Held twelfth | 35th, 44 laps down | Out |
Caruth won the pole, won stage two, and was turned into the wall late in regulation. He made the Chase anyway, because the stage points he banked early were worth more than the finish cost him.
The panel had him at 2.8% against a 5.5-cent midpoint on the reasoning that bubble drivers would points-race and stay out of the picture. That read was right on the settlement and wrong about how a bubble driver races. At Joe Gibbs Racing, Sawalich and Crews both wrecked out of the last two seats, and Gray, one point outside before the race, got in as the eleventh seed.
The Bottom Line
Before the race, the panel and the market agreed that all but two of the contracts belonged under a dime. They disagreed about the ceiling: the panel capped any favorite near 12 or 13%, and the market paid 18.5 cents for Hill.
The race answered with a name from the bottom, which is what a flat board means when it settles. Scored across all 39 contracts, the panel's median beat the market, and Hill's row and Sieg's row account for more than the whole gap, so the market priced the other 37 slightly better.
The usable rule is narrower than "buy the longshots": on a flat drafting-race board, compare the ignored names to a price-blind estimate, and size anything you like as if it will lose 30-odd times for every time it pays, because that is what a 3-cent price means over a large sample.
The Chase opens at Darlington on September 5 with Allgaier seeded first and Caruth twelfth.
