About This Event
Before 2028 If Scottie Scheffler wins the golf grand slam (winning the Masters, the PGA Championship, the U.S. Open, and the Open Championship) in a single year before Jan 1, 2028, then the market resolves to Yes. Early close condition: This market will close and expire early if the event occurs. This market will close and expire early if the event occurs.
What Prediction Markets Are Forecasting
Prediction market traders put roughly a 1 in 20 chance on Scottie Scheffler completing a single-season grand slam before 2028. That's a 5% probability, which means the market considers it very unlikely, though not impossible. To put it in perspective, you'd be more likely to flip a coin and get heads four times in a row (about 6%) than to see Scheffler pull this off.
The grand slam in golf means winning all four majors in the same calendar year: the Masters, the PGA Championship, the U.S. Open, and the Open Championship. No golfer has done it since Bobby Jones in 1930, and he was an amateur playing a different circuit. In the modern professional era, it has never happened.
Why the Market Sees It This Way
Traders are pricing in several realities. First, the sheer difficulty. Even Tiger Woods in his absolute prime, during his 2000-2001 run, won four consecutive majors but across two seasons, not one. Jordan Spieth came close in 2015, winning two and contending in the others, but fell short. The margin for error across four different courses, four different setups, and four weeks of peak performance is razor thin.
Second, Scheffler's game, while dominant, has shown cracks in the majors specifically. He has one Masters title (2022) and has finished top five in many others, but he hasn't converted his overall tour dominance into major victories at the rate you'd expect from a world number one. His putting has been streaky, and major championship pressure amplifies that.
Third, the field is deep. Players like Rory McIlroy, Jon Rahm, and Xander Schauffele are capable of beating anyone on any given week. One bad round, one bad bounce, one hot opponent, and the dream dies.
Key Dates and Events to Watch
The market closes early if Scheffler actually completes the slam. Watch the four major championships each year: the Masters in April, the PGA Championship in May, the U.S. Open in June, and the Open Championship in July. If he wins the first two or three, you'll see the odds shift dramatically. A strong showing at the Masters with a win would push this market up to maybe 15-20%. Two in a row and it could jump to 40% or higher.
Also watch his form heading into majors. His putting stats, his performance in the weeks before, and any injury news will move the market incrementally.
How Reliable Are These Predictions?
Prediction markets are generally decent at forecasting discrete, measurable outcomes, and this is one. But the sample size for grand slams is tiny, which makes calibration hard. Markets tend to be conservative on once-in-a-generation events, and 5% feels about right given historical frequencies. The real value here isn't the exact number, it's understanding that the market sees this as a long shot, not a fantasy. Scheffler is good enough that a 5% chance isn't crazy. It's just very, very hard.
Current Market Outlook
Kalshi traders price Scottie Scheffler completing the grand slam before Jan 1, 2028 at just 5%. That's a 20-to-1 long shot, which sounds extreme until you consider the math. Only five golfers in history have won all four majors in a single calendar year, and the last was Tiger Woods in 2000-01 (a "Tiger Slam" spanning two seasons). The modern schedule, with the PGA Championship sandwiched between the Masters and U.S. Open and the Open Championship in July, makes a true single-year sweep brutally demanding. A 5% price implies the market sees roughly a 1-in-20 chance over three full seasons, which breaks down to about a 1.7% chance per year. That's aggressive but not absurd given Scheffler's current dominance.
Key Factors Driving the Odds
Scheffler's baseline is extraordinary. He won the Masters in 2024, took Olympic gold, and claimed the 2024 Players Championship, but his major record outside Augusta remains a sore spot. Through 2025, he has zero PGA Championships, zero U.S. Opens, and zero Open titles. His putting volatility has cost him at U.S. Opens, where the firm, fast greens punish his occasional cold streaks with the flat stick. The market is pricing in that consistency gap.
Historical precedent matters here. Brooks Koepka won four majors between 2017 and 2019 but never threatened the single-year sweep. Rory McIlroy has been stuck on four majors since 2014. The gap between winning one major and winning all four in one season is wider than casual fans appreciate. Scheffler's ball-striking is historically elite, but the grand slam requires four distinct course setups, four different pressure environments, and a full year of physical and mental stamina.
What Could Change These Odds
The biggest catalyst is the 2026 and 2027 major schedules. The 2026 U.S. Open at Shinnecock Hills and the 2027 Open at Royal Birkdale favor elite ball-strikers, which plays directly into Scheffler's strengths. If he wins the 2026 Masters and follows with a PGA Championship, the market will reprice quickly, likely jumping to 20-30% mid-season. A wrist injury or a prolonged putting slump would push the price toward 2-3%, but his age (28 as of 2025) means he has a full prime window ahead.
The 5% price is a fair starting point, but the market is thin. Real money will move only when Scheffler wins the first leg of a potential slam, at which point the odds will shift dramatically. Right now, this is a lottery ticket with decent expected value for believers, not a serious investment.

Overview
Scottie Scheffler, the world's number one ranked golfer, is the subject of a prediction market asking whether he will win the golf grand slam before 2028. The grand slam in golf refers to winning all four major championships in a single calendar year: the Masters Tournament, the PGA Championship, the U.S. Open, and the Open Championship. This feat has never been accomplished in the modern era of golf, making it one of the most elusive achievements in the sport. The market resolves to 'Yes' if Scheffler wins all four majors in the same year before January 1, 2028, and it will close early if he achieves this historic feat. Scheffler's rise to prominence has been meteoric. He claimed his first major title at the 2022 Masters, and by 2024, he had added a second Masters victory, a Players Championship title, and an Olympic gold medal. His consistent performance, including a remarkable streak of top-10 finishes, has led many to consider him the best player of his generation. The prediction market taps into the possibility that he could replicate the dominance of legendary players like Tiger Woods, who won four consecutive majors across two seasons (2000-2001) but never the single-year grand slam. The interest in this market is driven by Scheffler's current form and the historical rarity of the achievement. Golf fans and bettors alike are drawn to the long-shot nature of the wager, as the odds of any player winning all four majors in a year are extremely low. The market's early close condition adds an extra layer of intrigue, as it will resolve immediately if Scheffler completes the sweep, making it a dynamic and potentially short-lived market. As of early 2025, Scheffler continues to be a dominant force, and his performance in the upcoming majors will be closely watched by those with a stake in this market.
Historical Context
The modern golf grand slam, defined as winning all four professional majors in a single calendar year, has never been achieved. The closest attempts came from Tiger Woods in 2000 and 2002, when he won three of the four majors in each year. In 2000, Woods won the U.S. Open, the Open Championship, and the PGA Championship, but finished fifth at the Masters. In 2002, he won the Masters, the U.S. Open, and the PGA Championship, but tied for 28th at the Open Championship. Prior to Woods, Ben Hogan won three majors in 1953, but he did not play in the PGA Championship, which conflicted with the Open Championship that year. Bobby Jones's 1930 grand slam is often referenced, but it consisted of the U.S. Open, the Open Championship, the U.S. Amateur, and the British Amateur. Since the modern era began in 1934, no professional has won all four majors in a single year. The difficulty is underscored by the fact that only five players have won the career grand slam (winning all four at different times): Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, and Tiger Woods. The last player to have a chance at the single-season grand slam was Jordan Spieth in 2015, when he won the Masters and the U.S. Open, but missed the cut at the Open Championship and finished second at the PGA Championship. Scheffler's own history in majors is impressive but not yet at the level of a single-season sweep. He won the Masters in 2022 and 2024, but his best finishes in the other majors have been a tie for second at the 2022 PGA Championship and a tie for third at the 2024 U.S. Open. The market's timeline, before 2028, gives Scheffler four more full seasons (2025, 2026, 2027) to achieve the feat, which aligns with his prime years at age 28 to 31.
Why It Matters
The possibility of Scottie Scheffler winning the grand slam before 2028 matters for several reasons. For golf fans, it would be a historic achievement that has not occurred in the modern era, potentially elevating Scheffler to the pantheon of legends like Tiger Woods and Jack Nicklaus. It would also have significant financial implications for the sport, as a grand slam would likely boost television ratings, sponsorship deals, and merchandise sales. The PGA Tour and its players would benefit from the increased attention, and Scheffler's own earnings could skyrocket, given that major victories already come with substantial prize money. Beyond the sport, the prediction market itself reflects the growing intersection of sports and finance. Markets like this allow fans and bettors to engage with outcomes in a more nuanced way, and the odds can shift based on performance data, injuries, and course conditions. The outcome of this market could also influence how future markets are structured for other sports, as it demonstrates the demand for long-term, prop-style bets on individual athletes. For Scheffler, the pressure of being the favorite in every major is immense, and his ability to handle that pressure will be a storyline for the next few years.
Current Status
As of early 2025, Scottie Scheffler is the clear favorite in the golf world, having won the 2024 Masters and the Olympic gold medal. He has also been dealing with a hand injury sustained in December 2024, which required surgery and could affect his early 2025 season. The injury has raised questions about his readiness for the 2025 majors, but his track record suggests he will recover and compete at a high level. The prediction market for the grand slam is active, with odds that reflect the long-shot nature of the bet, but Scheffler's recent performances keep the possibility alive. The next major, the 2025 Masters, will be a key indicator of his form and the market's direction.
