Will Scottie Scheffler Win The Grand Slam Before 2028?

There is no higher honor in golf than achieving a grand slam. Only Tiger Woods, Jack Nicklaus, Gary Player, Gene Sarazen, Ben Hogan, and Rory McIlroy have managed to enter the exclusive “four-major” club, but Scheffler isn’t far behind.

At Kalshi, the “Will Scottie Scheffler Win The Grand Slam Before 2028?” market has seen a fair bit of movement since first opening on June 1st, 2025. Scheffler’s single-stroke loss to Rory McIlroy at the 2026 Masters halted any chances of this market seeing a “Yes” outcome this year, but 2027 is still on the table.

What are Scheffler’s chances of actually winning a grand slam before 2028?

What Are Scottie Scheffler’s Grand Slam Chances in 2027?

Scheffler’s rise to golf stardom began with his first major championship victory at The Masters in 2022, where he won by a convincing three strokes.

This was part of a stretch where Scheffler won four tournaments in just six starts, at which point he became the World No. 1 in the Official World Golf Rankings (OWGR).

Since then, he’s won three more majors, including the 2024 Masters, the 2025 PGA Championship, and the 2025 Open Championship. Thus, the U.S. Open is the last major Scheffler needs to add to his collection.

His best U.S. Open results include a tie for second in 2022 and a third-place finish in 2023. Scheffler’s last two years at this major haven’t exactly been encouraging, finishing tied for 41st in 2024 and tied for seventh in 2025.

On the other hand, he certainly has the skill and the pedigree to do it. He’s been the top-ranked golfer for 155 consecutive weeks dating back to May 21, 2023.

For more perspective, that’s the longest streak since Tiger’s record of 281 weeks between 2005 and 2010. In total, Scheffler has spent 191 weeks in the top spot of the OWGR throughout his career.

His ability to always remain in the mix fuels optimism surrounding his grand slam chances, evidenced by a high volume of Top-10 finishes and the fact that he’s only finished outside the Top-25 in a major twice over the past four years.

What Does History Tell Us About Golf Grand Slams?

According to the official Kalshi market rules, Scheffler would need to be the first golfer in history to pull this off for any “Yes” contracts to hit.

While a grand slam of any kind is impressive, none of Woods, Nicklaus, Player, Sarazen, Hogan, or McIlroy completed their grand slams in a single calendar year.

When this Kalshi market first opened at the start of June 2025, Scheffler’s chances of a “Yes” outcome were already dashed for the year.

At that point, he had won the PGA Championship just weeks earlier, but had fallen short after tying for second at The Masters.

Still, there were two more full years for Scheffler to try and become the first-ever golfer to earn a Grand Slam within the same calendar year. As previously mentioned, there is now one (2027).

As such, there would be no better way to inspire fans and “Yes” contract shareholders alike heading into next year by winning his first U.S. Open before 2026 is out.

Of the players in the four-major club listed above, only Woods, Nicklaus, and Player managed to earn career grand slams before the age of 30.

The U.S. Open is set for June 12th-15th, and Scheffler is set to turn 30 on June 21st, meaning he still has the potential to join that exclusive group.

Which Scheffler Contracts Provide The Most Value?

For the moment, it predominantly makes sense to buy “Yes” contracts for ~8 cents each.

Logically speaking, buying the no makes more sense, but there’s not much profit to be earned without buying a very high volume at ~94 cents each.

For those looking to find Scheffler value on adjacent markets, he’s a good bet to be a Top 10 Finisher in All 4 Golf Majors, with “Yes” contracts going for just ~47 cents.
