Will Elon Musk visit Mars in his lifetime?
My independent estimate is that Elon Musk has a meaningful but still minority chance of personally visiting Mars before Aug. 1, 2099, at about 22%. The market’s 10% yes price looks too low if Musk remains alive and SpaceX or successor systems achieve routine Mars transport, but the event is still highly fragile because it depends on personal survival, capability, and willingness across a very long horizon.
Analysis
The core issue is that this is not a question about whether humans reach Mars or whether SpaceX lands hardware there; it is specifically about Elon Musk himself physically visiting Mars before 2099. Recent reporting still shows Musk and SpaceX treating Mars as a strategic goal, with Musk publicly pushing uncrewed Mars attempts and SpaceX framing Starship as the vehicle for Moon and Mars missions, but those plans have already slipped and remain pre-operational for Mars transport. That creates a real path to Yes, yet it is a path that still begins with unproven launch reliability, Mars entry and landing success, refueling, and a sustained campaign that has not started in practice.
The strongest argument for Yes is the unusually long time window. If Musk remains alive and even a modest fraction of SpaceX’s Mars ambitions are realized over the next seven decades, a personal Mars visit becomes plausible rather than fantastical. Musk has repeatedly signaled that Mars is a central objective, and recent coverage still includes explicit Mars timelines, even if they are optimistic or shifting; over such a long horizon, repeated launch windows and incremental progress could eventually produce a crewed mission with Musk aboard. The fact that the market question only requires a visit, not colonization or a long stay, also makes the threshold lower than many people instinctively assume.
The strongest argument against Yes is that the event is bottlenecked by many independent failure points. Musk must live long enough, remain physically capable, choose to go, and the entire Mars transportation stack must mature into something safe enough for a human trip. SpaceX has not yet sent anything to Mars, current timelines continue to move, and the company’s near-term priorities have emphasized the Moon and infrastructure development rather than a near-term human Mars mission. Given those constraints, the market’s low price is understandable, but it still appears somewhat conservative relative to the sheer length of time available and the possibility that Musk’s own probability-weighted odds improve dramatically if Mars becomes routine for others first.
Arguments
For
- Musk has repeatedly made Mars a top strategic goal, which increases the chance he ultimately tries to go.
- The long time horizon gives many opportunities for the technology and mission architecture to mature enough for a human visit.
Against
- Musk personally going is much narrower than a general Mars landing and depends on his own survival and choice.
- Current Mars plans are still delayed and unproven, so the technical path remains highly uncertain.
Key drivers
- The question is about a personal visit, so Musk’s longevity and willingness matter as much as SpaceX progress.
- A 75-year time horizon leaves room for multiple launch windows, iterative engineering, and eventual crewed Mars capability.
- Recent Mars timelines remain delayed, but they still indicate ongoing commitment rather than abandonment.
Risk factors
- Musk may not remain alive, healthy, or willing to travel to Mars by the time the capability exists.
- Starship or any successor system may never become reliable and safe enough for human Mars travel.
- SpaceX could reach Mars with cargo or other astronauts without Musk ever joining a mission.
Scenarios
Best case
SpaceX or its successors establish reliable Mars transport in the 2030s or 2040s, Musk stays healthy and motivated, and he joins a crewed mission as one of the early high-profile passengers.
Most likely
Mars missions eventually happen, but Musk either does not survive to the relevant era or chooses not to take the personal risk, leaving the market event unresolved in the negative.
Worst case
Musk never makes it because of death, declining health, personal choice, or a Mars program that remains too risky or too delayed for human passengers.

My independent estimate is well above the market’s 23% Yes price because the political direction, staffing pressure, and prior Trump-era hostility all point toward a serious elimination attempt.

Highest Google Gemini score on Humanity’s Last Exam in 2026?
AI39%MKT76%Edge-37HypedGemini has been improving quickly on related reasoning benchmarks, but the only directly cited Humanity’s Last Exam result is still 37.5% without tools, which leaves a meaningful gap to 50%. I think the market is overestimating the chance of a threshold-crossing score by year-end, though the probability is still material.
