Southern 500 Odds 2026: Kalshi's Darlington Winner Board

Kalshi's winner market for tonight's Cook Out Southern 500 held these prices an hour before the green flag with Tyler Reddick on top. Reddick, who won at Darlington in March and starts from the pole after lightning wiped out Saturday's qualifying, asks 19¢, roughly a 19% chance to win the NASCAR Cup Series playoff opener. Denny Hamlin is a penny behind at 18¢, a price his buyers refused to pay all of Saturday night and then paid from late Sunday morning on. Chase Briscoe, who has won the last two Southern 500s, is third at 14¢, up two cents on the day, the first time his ask has moved since the board's first full day.

Those prices are from 4:06 p.m. ET on Sunday, September 6, 2026, with the green flag moved up to 5 p.m. ET because of the evening rain threat. The board has traded 2,014,699 contracts since it opened on the evening of August 31, and 1,147,447 of them, 57%, printed in the last 24 hours. Between this morning's 7:18 a.m. pull and this one, 827,420 contracts crossed in the 22 driver markets we pulled. That is more than the whole board had traded between its listing and Saturday afternoon's pull, when lifetime volume stood at 807,285. That number is the reason to read this page off the bid and ask columns and not the volume column, and the rest of the page is the case for why. The most-traded market on the board over the last 24 hours belongs to a driver priced at 2¢, and by the end of this page you will know what all of those contracts were worth.

Every Driver With A Live Bid

The table is Kalshi's Southern 500 winner market (ticker KXNASCARRACE-COOOS26) as of 4:06 p.m. ET on Sunday, September 6, 2026. Each driver is a separate yes/no contract that pays $1 if he wins, the bid is what buyers offer, the ask is what sellers want, and cent prices read roughly as implied win percentages, a translation covered in our guide to Kalshi odds. Contracts traded is lifetime volume in that driver's market; the last column is the 24 hours before the pull.

Driver	Yes Bid	Yes Ask	Contracts Traded	Last 24 Hours
Tyler Reddick	18¢	19¢	138,761	61,232
Denny Hamlin	17¢	18¢	150,573	72,143
Chase Briscoe	13¢	14¢	104,002	56,991
Christopher Bell	7¢	9¢	142,493	96,088
Kyle Larson	8¢	9¢	87,149	43,704
Ryan Blaney	6¢	7¢	79,650	31,140
Ty Gibbs	5¢	6¢	93,697	22,376
William Byron	4¢	5¢	85,340	47,473
Brad Keselowski	3¢	4¢	115,772	60,317
Bubba Wallace	3¢	4¢	49,314	33,949
Chris Buescher	3¢	4¢	76,994	34,378
Carson Hocevar	2¢	3¢	110,178	62,903
Corey Heim	2¢	3¢	77,288	55,726
Chase Elliott	2¢	3¢	73,070	59,430
Joey Logano	2¢	3¢	67,621	52,619
Ryan Preece	1¢	2¢	110,307	101,622
Austin Cindric	1¢	2¢	46,826	19,913
Erik Jones	1¢	2¢	81,175	56,791
Daniel Suárez	1¢	2¢	42,858	37,452

The other 19 drivers on the board show a 1¢ ask with no bid behind it as of this pull. Ross Chastain is still among them after losing his bid overnight, and his market traded 43,626 contracts in the last 24 hours anyway, 31,493 of them since this morning's pull, every one a buyer at a penny. Josh Berry, whose bid vanished on Friday, took another 10,639 contracts at 1¢ in a single second at 3:50 p.m. and still has no bid. Chad Finchum, who replaced Gray Gaulding in the No. 66 for this race, finally saw his market trade for the first time on Sunday. Forty-five contracts printed, and every market on the board has now traded at least once.

Read the ask column and the board is orderly: three favorites in a five-cent band, then a step down to Bell and Larson, then the field. Read the volume column and it argues with the price harder than it did at any earlier pull. Hamlin leads lifetime volume, as the driver who was the favorite for most of the board's life should, but the second most-traded market on the board belongs to Christopher Bell at 9¢, whose 142,493 contracts put him ahead of the 19¢ pole-sitter. Brad Keselowski at 4¢ has out-traded Chase Briscoe at 14¢, and Ryan Preece at 2¢ has traded more contracts in 24 hours than any driver on the board, favorites included.

One caution before treating the table as a probability pie. The asks across all 38 drivers sum to 138¢ and the bids to 99¢, so the truth sits somewhere between the two columns, and on the cheap end of the board the spread is most of the price. Higher up it can open too: Bell's spread widened to two cents on Sunday, 7¢ bid against a 9¢ ask, after a single buyer took 20,000 contracts at 8¢ at 10:53 a.m., so his row on the table is the least settled of the top six. A board that turned over 57% of its lifetime volume in a day will keep moving through the pace laps, so re-run any arithmetic at the price you are actually offered.

What Moved Since Race Morning

Our first pull of this board was the morning of September 1, less than a day after it listed; Saturday's was 1:12 p.m. ET, before the weather; this morning's was 7:18 a.m., with the formula grid in hand. Here is where the markets that moved on Sunday stood at the morning pull and stand now, with the spot each driver starts from after qualifying was canceled and the grid was set by formula.

Driver	7:18 a.m. Bid / Ask	4:06 p.m. Bid / Ask	Change In Ask	Starts
Tyler Reddick	17¢ / 18¢	18¢ / 19¢	+1¢	1st
Denny Hamlin	16¢ / 17¢	17¢ / 18¢	+1¢	4th
Chase Briscoe	11¢ / 12¢	13¢ / 14¢	+2¢	7th
Christopher Bell	6¢ / 7¢	7¢ / 9¢	+2¢	11th
Brad Keselowski	2¢ / 3¢	3¢ / 4¢	+1¢	12th
Corey Heim	1¢ / 3¢	2¢ / 3¢	0¢, bid +1¢	22nd
William Byron	5¢ / 6¢	4¢ / 5¢	−1¢	20th
Erik Jones	2¢ / 3¢	1¢ / 2¢	−1¢	36th

Everything else on the priced board held both its bid and its ask through the day, including three markets that took real size without moving: Kyle Larson at 9¢ through 33,522 contracts, Chase Elliott at 3¢ through 53,334, and Carson Hocevar at 3¢ through 54,495.

The top of the board moved with the buyers paying up rather than the sellers backing off. Reddick's market traded 39,367 contracts after the morning pull and 37,094 of them were buyers taking the offer. The first print after our morning pull went through at 18¢ at 7:32 a.m., the first 19¢ print landed at 12:06 p.m., and in the next minute a buyer swept whatever was offered at 19¢, 20¢ and 21¢ before the sellers refilled at 19¢, where it has sat since. Hamlin's market is the counterweight again, and this time the counterweight moved: 49,166 contracts traded, 48,761 of them buyers, and at 10:57 a.m. his buyers paid 18¢, a price they had not paid at any point on Saturday night, when they took 17¢ all evening and never once needed 18. On Sunday, 34,712 contracts went through at 18¢ across 421 prints, and the sellers at 18¢ have absorbed all of it without lifting to 19.

Briscoe's move is the one that took all week. His ask closed at 12¢ every day from the board's first full day through Saturday's close, was still there at this morning's pull, and a 5,887-contract order at 11:26 p.m. on Saturday did not move it. On Sunday the buyers finally lifted it: 13¢ at 9:38 a.m., 14¢ at 10:05 a.m., a single print at 15¢ at 10:20 a.m., and 16,584 contracts at 13¢ and 14¢ by the pull. Of the 45,078 contracts his market traded on Sunday, all but 50 were buyers. The two-time defending winner, starting seventh, cost two-thirds of the pole this morning and costs nearly three-quarters of it now.

The tell on this tape

for five days the biggest orders on this board hit the asks and the asks held. On Sunday the asks on all three favorites finally lifted, and every one of them lifted because buyers paid the next cent, not because a seller pulled an offer.

The pairs are still here too. Saturday's edition of this page noted that size on this board arrives in pairs of contenders seconds apart, and Sunday's tape kept the habit: at 9:07:23 a.m. a buyer took 9,965 William Byron contracts at 6¢, and ten seconds later 24,755 Carson Hocevar contracts crossed at 3¢, 14,003 of them in one print. At 12:11:29 p.m. 2,627 Hamlin contracts went through at 18¢, and nine seconds later 3,925 Briscoe contracts went through at 12¢, two cents under the 14¢ it had already printed that morning. Byron's is the only one of those four markets that is lower at the pull, and his ask fell to 5¢ after a seller offered 4¢ and a buyer took 3,000 contracts there at 4:00 p.m., on a driver who starts 20th.

The market's read on the grid has not changed since this morning, and the day's biggest single prints were on the cheap end of it. Four orders of exactly 20,000 contracts landed on Sunday: Chase Elliott at 3¢ at 7:53 a.m., inside a 31,557-contract second; Bell at 8¢ at 10:53 a.m.; Ryan Preece at 2¢ at 1:03 p.m., inside a 53,042-contract second; and Keselowski at 3¢ at 2:49 p.m., inside a 25,742-contract second that lifted his ask back to 4¢, the cent he lost overnight. Two of those four asks held, Elliott's 3¢ and Preece's 2¢; the Bell and Keselowski prints each bought the next cent. The size on this board keeps arriving in round lots at the cheapest price on the ladder, and the sellers at those prices keep having more.

Who Should Be The Favorite: Reddick, Hamlin Or Briscoe?

The 19¢ on Reddick is a bet on the track as it exists in 2026, and on the grid. Darlington switched to NASCAR's short-track aerodynamic package this season, a change announced in the offseason, so only one Cup race has ever been run here under tonight's rules: the Goodyear 400 in March. Reddick won it, one of four wins this season, three of them in the year's opening three races, and he was the runner-up to Briscoe in this race a year ago. Saturday added the pole without a lap turned, which Reddick called "literally best-case scenario for us". One driver on the board has a win under the current package at this track, a podium in the most recent Southern 500 and the No. 1 starting spot tonight, and 19¢ is the price of all three.

The 18¢ on Hamlin is a bet on the season. He is the top seed in the 16-driver field that was settled at Daytona on August 29, after a summer stretch of three consecutive wins at Nashville, Michigan and Pocono, and he has won this specific race three times, most recently in 2021. He starts fourth. If you think the playoff opener goes to the best team in the sport right now, the No. 11 Joe Gibbs Racing Toyota is that team, and 18¢ is the price of agreeing. The hole in the theory is the March race: under the package tonight runs, Hamlin came home 11th at Darlington while Reddick won. Our NASCAR Cup champion odds page tracks how Kalshi prices his title chances across the full 10 races, and both boards move for the same reason: the market keeps paying for Hamlin's summer, and on Sunday it paid a cent more for it than it would on Saturday night.

The 14¢ on Briscoe is the theory the market trusted least all week, and on Sunday it trusted it a little more. Briscoe led 309 of 367 laps in last year's Southern 500, and beat Reddick to the line, one year after winning this race for the first time. A drive that dominant usually buys a driver the top of the next year's board. Instead the market charged 12¢ for it for five straight days, and even after Sunday's two-cent lift it charges five cents less for last September than for Reddick's March, a gap that says buyers believe the package change reset the track more than the result reset the driver. The one I keep coming back to is the timing: the buyers who lifted Briscoe on Sunday morning had the same grid the Saturday-night buyers had, and the Saturday-night buyers left him at 12.

The sportsbooks read the same three names differently, and for the first time this week their snapshot is fresh. DraftKings' Southern 500 odds, as published by FOX Sports at 12:40 p.m. ET on Sunday, had Reddick and Hamlin tied at +380 with Briscoe at +550. The implied percentages carry the book's margin, so they run high as a group.

Driver	Kalshi Ask (4:06 p.m.)	DraftKings Odds (12:40 p.m.)	DraftKings Implied
Tyler Reddick	19¢	+380	20.8%
Denny Hamlin	18¢	+380	20.8%
Chase Briscoe	14¢	+550	15.4%
Kyle Larson	9¢	+800	11.1%
Christopher Bell	9¢	+900	10.0%
Ryan Blaney	7¢	+1000	9.1%
William Byron	5¢	+1200	7.7%
Ty Gibbs	6¢	+1800	5.3%
Brad Keselowski	4¢	+1800	5.3%
Chase Elliott	3¢	+3000	3.2%

The row that stands out is Ty Gibbs's, because it is the only one that runs the wrong way. On every other driver the book's implied number sits above the exchange's ask, which is what a book's margin does; on Gibbs the exchange asks 6¢ for a driver the book prices at 5.3%, so the exchange is the expensive place to hold the one car that took the largest order on Saturday's tape. The Briscoe row has a track record: against FanDuel's +600 on the same FOX Sports page on September 2, his gap to the book was more than two points at every pull this week, and against DraftKings' +550 on Sunday it is 1.4, so the exchange has stopped being quite so cheap a place to hold the domination theory. Both columns carry margin, so read either gap as a direction rather than a number you can bet.

Does A Playoff Berth Buy A Price?

Add up the asks on the 16 Chase drivers and you get 110¢, against 93¢ of bids, up from 105¢ and 89¢ this morning. That five-cent gain is the day's cleanest measurement of how much the market thinks the postseason field matters at Darlington, and it is worth knowing what the field is actually racing for. NASCAR brought back the Chase format for 2026: the 16 drivers who made the field at Daytona race all 10 events with no elimination rounds, no cutoff races and no Championship 4, and a race win is worth 55 points rather than an automatic ticket to the next round, 75 if the winner sweeps both stages. Hamlin opens as the top seed with a 25-point edge on the second seed. So a Darlington trophy tonight is not an advance, it is the biggest single points swing available, and the market prices the group that can bank it as its heavy default while still leaving real prices on the outsiders.

The sum can pass 100¢ because each driver trades as his own contract with his own spread. A berth does not buy a price by itself, and the formula grid did not buy one either. Michael McDowell, Ricky Stenhouse Jr., Austin Dillon and Alex Bowman, none of them in the 16, start fifth, eighth, ninth and tenth, and none of the four has a bid. Playoff drivers Byron, Blaney and Larson start 20th, 24th and 25th, with Carson Hocevar 34th and Chris Buescher 35th, and only Byron lost a cent on Sunday. Blaney carries the day's other handicap: his No. 12 Ford failed pre-race inspection twice on Saturday before passing on the third attempt, which cost the team its car chief for the weekend and its pit-stall selection. His market took 22,825 contracts on Sunday, every one of them a buyer, and his 7¢ ask did not move. The honest counterweight to a page that keeps saying buyers paid the next cent is the two Chase markets where somebody was selling into the same tape: Joey Logano's, where 7,011 contracts were sellers hitting the bid, including a 4,000-contract sale at 2¢ at 4:00 p.m., 27 seconds before this pull, and Bubba Wallace's, where 2,089 contracts were sold at 3¢ at 1:35 p.m. Both asks held anyway. The market is paying for evidence at this track, under these rules, from these cars, and it weighs a starting spot at about a cent and a lost pit stall at nothing.

Why The Cheap Cars Take The Most Contracts

Contracts are not dollars, and that is the whole answer to the heading. A 2¢ contract costs a fiftieth of a 100¢ one, so a buyer with a fixed budget shows up on the cheap end of the board with 50 times the volume, and the lifetime column rewards conviction bought in bulk. On Sunday the bulk went to the car that starts third. Ryan Preece's market traded 101,622 contracts in the 24 hours before this pull, more than Hamlin's 72,143 and Reddick's 61,232 and more than any driver on the board, and 90,015 of them printed after this morning's pull, all at 1¢ and 2¢. The 1:03 p.m. second alone was 53,042 contracts at 2¢, a 20,000-contract print and a 7,600-contract print among them. At two cents a contract, the 90,015 since this morning come to about $1,800 before fees, and neither his bid nor his ask moved. Preece took the last spot in the field with his first points-paying Cup win at Daytona, starts third, on the inside of the second row directly behind Reddick, and asks the same 2¢ he asked on Saturday afternoon. The volume column says he is the story of the board. The price column says the story is worth 18 hundred dollars.

Contracts are not dollars

Preece's 101,622 contracts over 24 hours are about $2,000 of contracts at 2¢. Hamlin's 72,143 contracts at 17¢ and 18¢ come to about $12,600. The volume column ranks conviction bought in bulk, not money at risk, and on this board it ranks a 2¢ car first.

Bell is the other market the price history singled out, and he is not cheap, which is why his is the one Sunday move that reads as money rather than bulk. His market traded 69,138 contracts after the morning pull, all but 324 of them buyers, and the 20,000-contract print at 8¢ at 10:53 a.m. was the largest single order at a price above 3¢ in any of the 22 tapes we pulled. At 8¢ that one print is $1,600, nearly as much as Preece's entire day. It lifted his ask to 9¢ by 11:02 a.m., and a 3,656-contract print went through at 9¢ at 12:16 p.m., but the bid never followed past 7¢, which is why his row carries the widest spread in the top half of the board. Bell starts 11th, and the case for him is the Hamlin case at half the price: same Joe Gibbs Racing shop, same Toyota.

Ty Gibbs, eighth on the board in lifetime volume, is the same case at a further discount, with an average finish of 5.7 in the last three Southern 500s, including a runner-up in 2024. Gibbs starts 28th, and Sunday was quiet by this board's standards, 14,103 contracts, with the 6¢ ask that absorbed 26,836 contracts of buying in a single Saturday-morning burst still sitting where it was. Keselowski's Sunday sweep bought a driver who finished second to Reddick in March under the current package after leading 142 laps, then missed the field at Daytona; he starts 12th. Erik Jones at 2¢ has the longest memory on the board and lost a cent on Sunday anyway. Jones has won the Southern 500 twice, and in 2022 he held off Hamlin in the closing laps of this same playoff-opener slot as a non-playoff driver. Jones starts 36th, and a 9,358-contract print at 2¢ at 12:30 p.m. was not enough to keep a seller from taking his ask down to 2¢.

Josh Berry is the case that changed the most since September 1, in both directions, and Sunday did not change it back. When this page was first written his market was the most-traded on the board at 2¢ and his season looked like a reason to sell: by mid-June he sat 30th in points, and Wood Brothers Racing announced it would not bring him back for 2027. Since then the form has turned: a third at New Hampshire on August 23 for a fourth straight top 10, then a ninth at Daytona for five in a row. Berry starts 14th, his market has traded 79,210 contracts, and nobody is standing behind a 1¢ bid. Ross Chastain's market has done the same thing since Saturday night, a day of penny buying with no bid behind any of it. Price is probability and volume is sentiment, and they are allowed to disagree; at a penny, the same buyer can be the whole sentiment.

What Tonight Settles

The grid got set before the market did, just not the way anyone planned. Saturday's schedule had Cup practice at 4 p.m. ET and qualifying at 5:10 p.m.; persistent lightning kept the cars off the track through both, and the lineup came from NASCAR's formula instead, 30% owner standings and 70% finish at Daytona. Reddick starts first, Daniel Suárez second, Preece third, Hamlin fourth, and the 16 Chase drivers open the postseason without a lap of practice at Darlington under this package since March.

Weather can still take tonight away, which is why the race starts early. NASCAR moved the green flag up to 5 p.m. ET from 5:10, with pre-race coverage on USA Network from 4:30 p.m., and the National Weather Service forecast for Darlington, updated at 3 p.m. Sunday, puts the rain chance at 50% for the afternoon with a high near 92 and 50% again overnight. A 367-lap race that starts at 5 p.m. runs straight into that window. The contracts themselves are written for delay: each market's rule pays on whoever "finishes in first in the Main race at the 2026 Cook Out Southern 500 originally scheduled for Sep 6, 2026," so a race pushed to Monday still settles the same board.

The price history has already set up the argument tonight settles. Reddick's buyers paid up three times, at 16¢ during Saturday's lightning hold, at 18¢ after midnight with the grid in hand, and at 19¢ at noon on Sunday with nothing new to look at. Hamlin's buyers paid 17¢ all Saturday night and 18¢ from 10:57 a.m. on. A Reddick win from the pole says the buyers who chased the price had the better read; a Hamlin win from fourth says the ones who sat on the offer did, and did not lose anything by waiting a day to pay the extra cent. Briscoe at 14¢ from seventh is the cheaper way to bet that neither theory matters as much as last September's 309 laps, and it is two cents less cheap than it was this morning. And a car from outside the 16, Erik Jones from 36th or Corey Heim from 22nd, would spoil the opener the way Jones did in 2022, hand nobody in the Chase the 55 points, and turn a 2¢ or 3¢ contract into $1. The thing to watch first is whether Reddick holds the front through the opening stage: the extra cent the market added at noon is worth exactly as long as the pole is.

Because Kalshi is an exchange rather than a sportsbook, none of these positions has to be held to the flag: if Reddick runs away with the first two stages from the pole, holders can sell before the checkered flag, and Kalshi's trading fee comes off at whatever price you trade.
