Will Scottie Scheffler win the grand slam before 2028?
Scottie Scheffler has a real but still modest chance to complete the career grand slam before 2028. His elite baseline skill makes the market’s 5% feel too low, but the task remains difficult because he still needs to capture at least two specific majors in a short window.
Analysis
Scheffler is the type of player who can make even a low-probability feat feel plausible. He has been the best or one of the best golfers in the world for multiple seasons, which gives him repeated access to contention in every major, and his consistency means he does not need a perfect week to win. If he still has at least two of the four majors left to complete the career grand slam, his path is difficult but clearly alive because he can simply pile up attempts in 2026 and 2027 while remaining a favorite or near-favorite in many elite fields.
The main reason the probability stays well below 50% is that completing the grand slam is inherently rare, and the remaining majors are not interchangeable. One missed opportunity in the U.S. Open or Open Championship can erase a season’s progress, and even the best player in the world can go years without winning a specific major due to course fit, weather, randomness, and the small margins that define major championships. The time window before 2028 is also short, so there are only a handful of serious shots left.
The market’s 5% pricing looks aggressive on the low side. That price implies Scheffler is only a longshot to win the remaining pieces of the grand slam, but his actual talent level, age, and frequency of contention make that too pessimistic. A more reasonable estimate is in the high teens: still a minority outcome, but materially more likely than the market suggests because one of the best golfers of his generation does not need a long time horizon to add two majors.
Arguments
For
- He is consistently among the strongest players in the world, which materially raises his chance of winning any given major.
- If he already owns most of the grand slam, only a small number of remaining wins are needed before 2028.
Against
- Winning multiple specific majors in under two years is still a low-probability task even for a dominant player.
- Major championships are noisy, and course-specific variance can block the best golfer from converting chances.
Key drivers
- Scheffler’s elite baseline gives him repeated major contention opportunities each season.
- The short deadline means only a few good breaks or peak performances are needed to finish the remaining majors.
Risk factors
- He may still need multiple specific majors, and each one is highly volatile even for the world’s best player.
- A short horizon leaves little room for injury, form slumps, or simply bad variance in a few key starts.
Scenarios
Best case
Scheffler stays healthy, remains the top player in the world, and captures the remaining major titles in 2026 or 2027 to complete the career grand slam before the deadline.
Most likely
Scheffler wins at least one more major but falls short of completing the full grand slam before the cutoff, making 'No' still more likely than 'Yes' despite the market’s extreme skepticism.
Worst case
He continues to contend but fails to win one or both of the required majors, leaving the grand slam unfinished by 2028.
