Will Scottie Scheffler win the grand slam before 2028?

Scheffler is already in the rare category of all-time great major winners, and the remaining step is not winning a first major but adding one more title to complete the set. That matters because the path to a career Grand Slam is much easier for an elite player with multiple majors, top-tier ball striking, and a long runway of starts before 2028. If he is still healthy and in peak form, he will have several chances at the Open Championship and the other majors, and any one victory at the right event would resolve the market in his favor.

The main reason the probability is not higher is that even dominant players rarely convert one specific major into a sure thing within a two-year window. The Open Championship is especially volatile because links golf adds weather, course setup, and randomness that can neutralize the best player in the world. Scheffler may also face ordinary major variance, injury risk, or a short slump at the wrong time, and the market only needs one missing title, not a broad continuation of excellence.

Compared with the current 5% market price, this looks heavily underestimating his true chance. Five percent would imply the event is close to a longshot, but Scheffler is already one of the very few active players with a legitimate near-term path to the career Grand Slam, and he has enough starts before 2028 that the cumulative odds should be materially higher. The market may be anchoring on how hard the Open is or on the fact that no one can win a major on demand, but that still does not justify pricing a player of Scheffler’s stature as if the outcome is almost impossible.
