The Quick Answer
Kalshi's BMW Championship top 5 finish board (ticker KXPGATOP5-BMC26) traded 199,712 contracts in a single day. As of this page's snapshot at 2:42 a.m. ET on Thursday, August 20, 2026, that 24-hour burst is 75% of everything the board has traded since it listed Monday afternoon. Scottie Scheffler sits at 57¢ bid / 58¢ ask to finish top 5 at Bellerive, and no other golfer in the 50-man field clears 26¢. Rory McIlroy took the hardest hit of the repricing, sold from 29¢ Monday down to a 23¢ bid this morning, hours before Round 1. The full 50-name board, the top 10 prices, the four-rung price ladder on Scheffler, and the tie math that paid six names last week are all below.

A 200,000-Contract Wednesday
The board is new. Kalshi listed the BMW Championship top 5 and top 10 markets on Monday, August 17, at 4:10 p.m. ET, three days before the first tee. Through Tuesday they mostly sat there. Then Wednesday happened: of the 264,812 contracts the top 5 board has traded in its lifetime, 199,712 changed hands in the final 24 hours before Thursday's opening round.
Nobody withdrew and nothing broke. The calendar did this. Placement boards on a no-cut event follow a rhythm you can set a watch to: they list early in the week, trade thin while the range feels theoretical, then absorb nearly all of their volume the day before the tournament starts, when paper positions become real ones. Our first round leader page watched the same Wednesday wave hit its own board.
What matters is what the wave did to prices, because Wednesday's money did not treat the field evenly. It made the favorite more expensive and the next tier cheaper:
- Scottie Scheffler firmed from 56¢ in Monday evening's first prints to 58¢ at the ask this morning.
- Rory McIlroy was sold from 29¢ Monday to a 23¢ bid, the biggest slide among the favorites.
- Tommy Fleetwood drifted from 25¢ to a 20¢ bid.
- Matt Fitzpatrick went from 24¢ to 19¢ bid, and Si Woo Kim from 22¢ to 18¢.
- Xander Schauffele and Ludvig Åberg barely moved, holding in the mid-20s all week.
One golfer up, four golfers down, two flat. Hold that shape in your head, because the winner board prices the same names in a very different order, and the gap between the two boards is the most useful thing on this page. McIlroy is the sharpest version of that gap, and I will come back to him.
The Kalshi Top 5 Board
Prices below were pulled from Kalshi's live API at 2:42 a.m. ET on Thursday, August 20, 2026, hours ahead of Round 1 tee times at Bellerive Country Club in St. Louis. "Market read" is the bid/ask midpoint expressed as a probability. The board carries all 50 golfers in the field; the 34 names below Justin Thomas trade between 3¢ and 13¢.
| Golfer | Yes Bid | Yes Ask | Market Read |
|---|---|---|---|
| Scottie Scheffler | 57¢ | 58¢ | 57.5% |
| Xander Schauffele | 24¢ | 26¢ | 25.0% |
| Ludvig Åberg | 24¢ | 25¢ | 24.5% |
| Rory McIlroy | 23¢ | 24¢ | 23.5% |
| Sam Burns | 21¢ | 22¢ | 21.5% |
| Cameron Young | 21¢ | 22¢ | 21.5% |
| Tommy Fleetwood | 20¢ | 22¢ | 21.0% |
| Matt Fitzpatrick | 19¢ | 20¢ | 19.5% |
| Si Woo Kim | 18¢ | 19¢ | 18.5% |
| Hideki Matsuyama | 16¢ | 17¢ | 16.5% |
| Chris Gotterup | 16¢ | 17¢ | 16.5% |
| Patrick Cantlay | 15¢ | 16¢ | 15.5% |
| Viktor Hovland | 15¢ | 16¢ | 15.5% |
| Collin Morikawa | 13¢ | 15¢ | 14.0% |
| Wyndham Clark | 13¢ | 14¢ | 13.5% |
| Justin Thomas | 12¢ | 13¢ | 12.5% |
The row that defines the board is the first one. There are five paying slots on a top 5 market, and at 57.5% the market has effectively handed one of them to Scheffler before a shot has been struck. Read it from the other side: 49 golfers are fighting over four remaining chairs, which is why the second tier compresses so hard. The distance from Schauffele in second to Fleetwood in seventh is four cents. The distance from Scheffler to Schauffele is thirty-two.
One structural note before you treat those midpoints as probabilities. Summed across all 50 names, the asks on this board come to about 613¢. A board that always pays exactly five winners would sum to 500¢, so the extra 113¢ is the cost of doing business: part bid/ask spread, and part insurance the market charges because ties can push the payout list past five names. This is an independent-binary board where each golfer settles on his own; the sum is a sanity check, not something you normalize away the way you would on a one-winner market.
The Top 10 Board Tells The Same Story, Louder
The top 10 board (KXPGATOP10-BMC26) listed the same Monday afternoon and covers the same 50 names, with ten paying slots plus tie spillover. Here is the top of it from the same 2:42 a.m. ET capture:
| Golfer | Yes Bid | Yes Ask | Market Read |
|---|---|---|---|
| Scottie Scheffler | 71¢ | 72¢ | 71.5% |
| Xander Schauffele | 41¢ | 42¢ | 41.5% |
| Ludvig Åberg | 41¢ | 42¢ | 41.5% |
| Rory McIlroy | 40¢ | 41¢ | 40.5% |
| Sam Burns | 37¢ | 38¢ | 37.5% |
| Tommy Fleetwood | 36¢ | 37¢ | 36.5% |
| Matt Fitzpatrick | 35¢ | 36¢ | 35.5% |
| Cameron Young | 35¢ | 36¢ | 35.5% |
| Si Woo Kim | 33¢ | 34¢ | 33.5% |
| Hideki Matsuyama | 31¢ | 32¢ | 31.5% |
Scheffler at 71.5% to be top 10 in a 50-man field is a remarkable price for a market to sit on comfortably, and it sat there through the heaviest trading day the board has had. Below him, notice the shelf: Schauffele, Åberg and McIlroy stacked within a cent and a half of each other at 40-42¢, exactly the trio that occupies spots two through four on the top 5 board. The asks across all 50 names sum to roughly 1,146¢ against a 1,000¢ ten-slot baseline, the same spread-plus-ties premium wearing a bigger coat.
That shelf is what makes the next comparison worth your time.
Same Golfer, Four Prices
Kalshi also runs a winner market and a top 20 board on this tournament, which means every golfer at Bellerive has four simultaneous prices this morning. Lined up, at the ask:
| Golfer | Win | Top 5 | Top 10 | Top 20 |
|---|---|---|---|---|
| Scottie Scheffler | 24¢ | 58¢ | 72¢ | 89¢ |
| Rory McIlroy | 5.5¢ | 24¢ | 41¢ | 65¢ |
| Xander Schauffele | 5.3¢ | 26¢ | 42¢ | 66¢ |
| Ludvig Åberg | 5.2¢ | 25¢ | 42¢ | 66¢ |
| Sam Burns | 4.2¢ | 22¢ | 38¢ | 61¢ |
| Tommy Fleetwood | 3.8¢ | 22¢ | 37¢ | 65¢ |
This ladder is the practical answer to a question American golf bettors run into every playoff week: each-way betting, the combined win-and-place ticket, is not offered at US books, so if you want to be paid for a near-miss, standalone placement markets like these rungs are the play. The ladder also does honest analytical work. A win price is a bet on a ceiling. A top 5 or top 10 price is a bet on a floor, the kind built from tee-to-green consistency and bogey avoidance rather than one hot putting week.
Which brings me back to the name I flagged at the top. McIlroy is the second-most-expensive golfer in the field to win this tournament at 5.5¢, ahead of Schauffele and Åberg. But on the top 5 board, Wednesday's flow dropped him below both of them, a fifth off his Monday price. The market spent its biggest trading day saying something specific about him: full faith in the ceiling, fading confidence in the floor. Whether you read that as a warning or as the discount on the board is exactly the kind of judgment these markets exist to price, and it is the one I keep turning over as Thursday's tee times get close.
Scheffler's ladder deserves one sentence of its own: the market says he is more than twice as likely to finish top 5 (57.5%) as to win (23.5% at the mid), and nearly nine-in-ten to be top 20. Nobody else's rungs are spaced anything like that.
The Tie Math And The Withdrawal Rule
Two pieces of fine print decide what these contracts are actually worth, and both come straight from the market rules.
First, ties. Each market resolves Yes if the golfer finishes in the top 5 (or top 10) including ties. There is no dead-heat reduction the way a sportsbook would chop a tied place bet; a Yes is a full $1 no matter how crowded the finish line is. That is not a rare edge case. Last week at the FedEx St Jude Championship, ties pushed six names to a full payout on the top 5 board and eleven on the top 10 board. The tie premium is part of why the ask sums run over their baselines, and on crowded leaderboards it works in the holder's favor.
Second, withdrawals. If a golfer withdraws before teeing off, the market resolves to Fair Market Price; once he has hit a shot, a withdrawal settles No. On a board captured the night before Round 1, that distinction is the difference between getting your value back and losing the whole stake, and it is worth knowing before you hold a position through Thursday morning.
And one feature of this specific week removes a variable entirely: the BMW Championship is the 50-man second leg of the FedEx Cup Playoffs, and there is no cut. Every name on these boards plays 72 holes. A bad Thursday cannot knock anyone off the course; it can only reprice them. Last week proved how much that matters — half of the six golfers who cashed the top 5 board were not among the fifteen most expensive names when that page was captured mid-tournament. On a no-cut board, cheap contracts stay alive all the way to Sunday.
How To Shop These Prices
The most actionable thing on this page is the disagreement Wednesday created. The exchange spent its biggest trading day cutting McIlroy's top 5 price by a fifth while leaving his win price near the top of the field; if a sportsbook's top 5 finish market has not made the same adjustment this morning, one of those two prices is wrong, and finding out which is the whole game.

The boards above are a snapshot from 2:42 a.m. ET Thursday. By the time the leaders make the turn, Wednesday's 200,000 contracts will look like a warmup, and the question the market spent all that money arguing about — whether the second tier's floors deserve their prices — starts getting answered one hole at a time.

FAQ
Does Kalshi have BMW Championship top 5 and top 10 odds? Yes. Kalshi lists top 5 (KXPGATOP5-BMC26) and top 10 (KXPGATOP10-BMC26) finish markets on all 50 golfers in the 2026 BMW Championship field at Bellerive, alongside winner, top 20 and first round leader boards. The markets settle after the tournament ends Sunday, August 23.
How many golfers can cash a top 5 board? At least five, and more if there are ties, since the markets resolve Yes for every golfer who finishes top 5 including ties. Last week's FedEx St Jude boards paid six names on top 5 and eleven on top 10.
What happens to my contract if a golfer withdraws? Before he tees off, the market resolves at Fair Market Price. After he has started play, a withdrawal resolves No.
