Will Elon Musk visit Mars in his lifetime?
Elon Musk has a non-trivial chance to visit Mars before 2099, but it remains a long-shot because the mission has to become technically real, safe enough for humans, and compatible with his health and lifespan. I put the odds modestly above the market at 14%.
Analysis
The core fact is that Musk is not just a casual Mars supporter; he has repeatedly made Mars colonization a central personal objective and has the resources and influence to push SpaceX toward it. With nearly three-quarters of a century remaining until the deadline, the relevant question is less whether he wants to go and more whether the transport system for a human Mars trip becomes real while he is still alive, fit, and willing to fly. That makes the outcome genuinely possible, but far from likely.
The biggest drag on the probability is that everything required for a personal Mars visit is still speculative: Starship must become highly reliable, human-rated, and capable of long-duration deep-space missions, and the broader infrastructure for landing, return, and life support must exist. History argues for caution because ambitious Mars timelines have repeatedly slipped, and the first operational Mars voyages, if they happen, may prioritize cargo, robots, or other astronauts rather than the founder himself. The result is that the path to a Musk visit is much narrower than the path to a generic Mars mission.
Against the market’s 9% price, I think the market is somewhat too pessimistic, though not wildly so. A 14% estimate reflects both the enormous difficulty and the long time horizon: Musk could still be alive in the 2030s or 2040s, and if SpaceX or another system eventually makes routine crewed Mars travel plausible, he is among the most motivated people on earth to try it. The market seems to underweight optionality and overemphasize the fact that there is no confirmed mission today, but the probability still stays low because the technical and personal hurdles are severe.
Arguments
For
- Musk has both the wealth and the institutional control to turn a personal Mars trip from a fantasy into a plausible mission objective.
- If SpaceX eventually develops crewed Mars capability, Musk has strong incentive to be one of the first participants.
Against
- No confirmed Mars mission for Musk exists, and current plans still focus on uncrewed flights and robots first.
- The combination of technical difficulty, age, and mission danger makes a personal Mars visit much harder than simply building Mars hardware.
Key drivers
- Musk has explicit personal interest in going to Mars, which increases the chance he would choose to fly if a credible mission exists.
- The deadline is extremely long, so a breakthrough in human Mars transport later this century could still make the event possible.
Risk factors
- Human Mars transport may never reach the level of safety and reliability needed for a private passenger.
- Musk may not remain alive, healthy, or willing to take the risk when a Mars mission finally becomes available.
Scenarios
Best case
SpaceX or another system makes crewed Mars travel routine by the 2030s or 2040s, Musk remains healthy enough to fly, and he becomes one of the first high-profile humans to land on Mars.
Most likely
Mars missions happen eventually but remain robotic or crewed by others, while Musk stays on Earth and his personal visit never materializes.
Worst case
Mars transport remains too dangerous or undeveloped, or Musk does not survive or choose to take the trip, so the event never occurs.

Which agencies will Trump eliminate?
AI84%MKT29%Edge+55Hidden GemUSAID looks much more likely than not to count as eliminated during Trump’s term, because the administration has already dismantled its independent operations and shifted its functions into the State Department. The main uncertainty is whether the market requires formal legal abolition, but even under that standard the path toward Yes remains materially stronger than the current price implies.
