FedEx St Jude First Round Leader Odds: Kalshi's Flattest Board Of Playoff Week
The Quick Answer
The FedEx St Jude first round leader market on Kalshi (ticker KXPGAR1LEAD-FESJC26) carries 69 golfers in the FedExCup Playoffs opener, and nobody on the board costs more than 7 cents. Scottie Scheffler leads the board at 5.3 cents bid / 7 cents ask, roughly a 6% chance to be on top of the leaderboard when Round 1 ends at TPC Southwind on Thursday, August 13, 2026. This is a one-day, high-variance market: it settles tonight, ties split the payout, and 2.28 million contracts changed hands in the last 24 hours alone. The full board, the tie rule that rewrites the payout math, and the way experienced traders actually approach a first round leader market are all below.
The Kalshi First Round Leader Board At TPC Southwind
One round of golf is the closest thing Kalshi lists to a pure variance market, and the prices say the crowd knows it. The best player in the world is a single-digit percentage. All but six of the 69 names cost under 3 cents at the ask. The question this page answers is not "who is the best golfer in Memphis" — the tournament winner market already answers that — it is how a market this flat actually pays, because the structure, not the leaderboard, is where most of the money is won and lost. Keep the tie rule in mind as you scan the board; we will come back to it, because it changes the math more than any name below.
Here is the top of the board, pulled directly from Kalshi's live API early Thursday morning (all prices in cents; "market read" is the bid/ask midpoint expressed as a probability):
| Golfer | Yes Bid | Yes Ask | Market Read | Contracts Traded |
|---|---|---|---|---|
| Scottie Scheffler | 5.3¢ | 7.0¢ | ~6% | 298,126 |
| Rory McIlroy | 3.0¢ | 3.8¢ | ~3% | 68,087 |
| Sam Burns | 2.5¢ | 3.0¢ | ~3% | 126,763 |
| Xander Schauffele | 2.1¢ | 3.3¢ | ~3% | 59,993 |
| Ludvig Aberg | 2.4¢ | 2.9¢ | ~3% | 55,737 |
| Tommy Fleetwood | 2.0¢ | 3.2¢ | ~3% | 97,191 |
| Collin Morikawa | 2.4¢ | 2.7¢ | ~3% | 52,162 |
| Hideki Matsuyama | 2.4¢ | 2.5¢ | ~2% | 118,978 |
| Matt Fitzpatrick | 2.0¢ | 2.7¢ | ~2% | 36,456 |
| Cameron Young | 1.0¢ | 3.6¢ | ~2% | 107,892 |
| Viktor Hovland | 2.2¢ | 2.4¢ | ~2% | 76,485 |
| Jackson Koivun | 2.2¢ | 2.3¢ | ~2% | 187,474 |
The rest of the board runs from the mid-2-cent range down, with tail names like Patrick Rodgers and Matti Schmid sitting under a penny.
Two rows are worth reading closely. Scheffler's is the obvious one: 298,126 contracts traded, the most on the board, at a price that still says he probably will not lead. The more interesting row is Jackson Koivun at 2.2 cents, the second-most-traded name here with 187,474 contracts. The crowd has picked its lottery ticket, and it is not any of the household names sitting above him on the board.
Why Nobody On This Board Costs More Than 7 Cents
Compare this market to its sibling. On Kalshi's tournament winner board for the same event, Scheffler trades at 15 to 16 cents, roughly a 15% chance to win the tournament outright across 72 holes. To lead after one round, he is 6%. That gap is the whole story of first round leader as a bet type: over 72 holes, skill separates; over 18, a hot putter and a good draw can put almost anyone on top, and the board is 69 names deep in a no-cut playoff event. TPC Southwind sharpens the effect. It is a par-70 where water is in play on 11 holes, so one loose swing erases a low round in progress, and Thursday regularly ends with a pack of players stacked at the top rather than a runaway leader.
The number I keep coming back to is the spread between the sums. Add up every ask on the board and you get about 130% of face value; add up every bid and you get roughly 87%. On a market that settles in hours, that is not a hidden 30% rake, it is 69 thin books with wide gaps between them (here is what a prediction market price really means if you want the mechanics). The practical consequence: on this board, market orders pay a real tax. If you trade it, work limit orders inside the spread, the way you would shop for the fair price of any line.
The Tie Rule Rewrites The Payout Math
Now the promised fine print. Kalshi's rules for this event state that if one golfer leads outright when Round 1 ends, his Yes contracts pay $1. But if multiple players are tied for the lead, Yes pays $1/N, rounded down to the nearest cent, where N is the number of players tied. A two-way tie pays 50 cents, a three-way tie pays 33 cents, a five-way tie pays 20 cents. The No side of a tied golfer pays $1 minus the Yes payout. Sportsbooks handle first round leader ties with their own dead-heat reductions; on Kalshi the reduction is written into the contract, and on a soft scoring day with a bunched leaderboard it is closer to the base case than the exception.
Worked Example: A Three-Way Tie At The Top
Say you buy 100 Yes contracts on Tommy Fleetwood at his 3.2-cent ask. That costs $3.20, plus Kalshi's trading fee of 0.07 x price x (1 - price) per contract, about 22 cents on this order, for a total near $3.42.
- Fleetwood Leads Outright: contracts pay $1 each. You collect $100.
- Fleetwood Is One Of Three Tied Leaders: contracts pay 33 cents. You collect $33.
- Fleetwood Is One Of Five Tied Leaders: contracts pay 20 cents. You collect $20.
- Anything Else: you collect $0.
Notice what the tie rule does and does not do at these prices. Even the five-way tie returns almost six times your cost, so a tie is not the risk; the binary miss is.
The one rule to remember: a tied leader does not pay $1. The rule matters most at the moment you are tempted to buy a "leader" mid-round at 60 or 70 cents while three players share the number: that contract's realistic ceiling may be 33 cents, not $1.
How Traders Actually Approach A First Round Leader Market
The golf-betting playbook for first round leader is structural: the draw and the day's weather, fast starters over players who build into a week, and putting heat, because a single low round is usually a putting round. Check Thursday's tee sheet and forecast yourself before trading; none of those angles requires you to believe Fleetwood is a better golfer than Scheffler, only that one round breaks a particular way. This board suggests the crowd is not trading those angles at all. Look back at the volume column: the two most-traded names after Scheffler are Jackson Koivun (187,474 contracts at about 2 cents) and Eric Cole (161,310 contracts, also around 2 cents), classic lottery-ticket accumulation at the cheap end of the board rather than a structural read on the draw. That is also why this market traded 2.28 million contracts in the 24 hours before Thursday's first tee, about 61% of its 3.7 million lifetime total: it is a trading product as much as a betting one, open while the round is being played, with prices repricing shot by shot until a leader is declared and the market closes early.
Ground rules if you step in. First, size for variance: Scheffler's 7-cent ask still implies a 93% chance he does not lead, and the top ten asks combined barely reach 35%, so most tickets on this board lose by design. Second, the wide spreads mean entries matter as much as opinions. Third, know your venue rules; Kalshi is a CFTC-regulated exchange, and where it is legal differs from sportsbooks, which is part of why golf props price differently across the two (the Kalshi vs DraftKings comparison walks through that gap).
Sportsbooks hang first round leader odds on this same tournament, and the number on the same golfer will not match this exchange's price 1:1; different liquidity and different fee math see to that. That is the one habit that transfers from every market on this page: never pay the first number you see.

Trade The Round, Then Zoom Out
The flattest board of playoff week is flat for a reason: one round of golf at a water-guarded par 70 is a coin cascade, and Kalshi's crowd has priced even the world No. 1 accordingly. Play it for what it is, a structure game of ties, spreads and timing that resolves tonight. Then remember the callback from the top: the same exchange prices Scheffler at 15 to 16 cents to win the whole tournament through Sunday. Conviction about who the best golfer in Memphis is belongs on the FedEx St Jude Championship winner board, where four rounds give skill room to show up. Tonight's leader market is for traders. This weekend's winner market is for believers.
