Will Scottie Scheffler win the grand slam before 2028?

My independent view is that Scottie Scheffler still has a meaningful shot to complete the career grand slam before 2028 because the remaining runway is concentrated into four major championships and his baseline level remains elite. Even in a season that has not produced many wins, he is still the kind of player who can show up as a favorite or near-favorite in multiple majors, and that profile matters a lot when the only thing left is to catch one tournament title in a relatively small sample of chances.

The case against is that major championships are volatile, and Scheffler does not need just any win, but the right one in the right stretch. If the missing major is one where course fit, weather, or putting variance matter disproportionately, his path is narrower than his overall talent suggests. The recent lack of conversion in 2026 also matters, not because it changes his true skill level much, but because it shows how easy it is for even the best player to come up short over and over in golf’s highest-leverage events.

Compared with the current market price of 6%, my estimate is much higher because the market seems to be pricing this as a long-shot rather than a strong elite-player future. That may reflect recency bias from his modest 2026 win total and the fact that one major still has to break his way, but a 6% implied probability looks too low for a player with Scheffler’s talent and a multi-major window still ahead. The market appears to be underweighting how often top-tier players can turn a four-attempt horizon into a single breakthrough.
