Will Scottie Scheffler win the grand slam before 2028?
Scottie Scheffler has a meaningful but not overwhelming chance to complete the career Grand Slam by early 2028. I make this substantially higher than the market, because one remaining major title is a realistic target for a player of his caliber over the next two seasons.
Analysis
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.
Arguments
For
- He is already a proven major winner with the skill set that travels across different major setups.
- There are enough major opportunities before 2028 that one breakthrough result is plausibly achievable.
Against
- Completing the career Grand Slam requires winning a specific remaining major, not just being elite overall.
- Major championships are low-conversion events, so even the best players can go multiple seasons without the needed win.
Key drivers
- Scheffler only needs one remaining major to complete the career Grand Slam, which is far less demanding than winning four separate majors.
- His elite tee-to-green consistency gives him repeated realistic win equity across multiple major championships before 2028.
Risk factors
- The Open Championship can be highly random because weather and links conditions create a wide variance environment.
- Injury, form regression, or simple major-week variance could leave him short even if he remains one of the best players in the world.
Scenarios
Best case
Scheffler stays healthy, keeps contending in majors, and captures the missing major before 2028, likely through another dominant all-around week.
Most likely
Scheffler contends several more times and wins at least one major, but the specific remaining title is still difficult enough that the Grand Slam is not guaranteed by early 2028.
Worst case
He remains among the top players in the world but fails to win the remaining major by the cutoff, leaving the career Grand Slam incomplete.

Will OpenAI or Anthropic IPO first?
AI12%MKT97%Edge-85HypedAnthropic appears materially more likely to go public before OpenAI, based on the latest reporting and each company’s stated timing. I assign only a low probability that OpenAI is first, because the newer evidence points to Anthropic’s nearer-term listing window and OpenAI’s delay into 2027.

How many Fed rate cuts in 2026?
AI38%MKT93%Edge-55HypedNo Fed rate cuts in 2026 is plausible, but I still think it is less likely than not because the Fed has historically been willing to ease when labor data soften or inflation cools enough. The market’s very high Yes price looks too confident, but the official projection path and the remaining months still leave meaningful room for one cut.
