Will Elon Musk visit Mars in his lifetime?

My independent read is that this is closer to an even-money or modestly favorable proposition than a long shot. Musk is still relatively young in 2026, has repeatedly framed Mars as a personal objective, and the window before 2099 is long enough for multiple Mars launch opportunities, multiple iterations of Starship, and potentially a second-generation transport system if the first one stalls. If human Mars travel becomes routine or even merely possible within the next few decades, Musk has a plausible path to board at least one mission while he is still alive and physically capable.

The main reasons to discount the yes case are real but not overwhelming. The technical stack is extremely hard, especially orbital refueling, crew safety, and surface support, and a Mars program can fail for decades before succeeding. There is also nontrivial personal risk: Musk could die, become too frail, or simply decide not to go once the danger is clearer. Still, the question is not whether a Mars visit happens soon; it is whether it happens by 2099, and that is a very different bar. Over 73 years, even a slow, stop-start space program has a lot of opportunities to eventually produce a mission he could join.

At 13%, the market looks too bearish. That price appears to heavily weight the difficulty of Mars settlement and Musk-specific mortality, but it seems to underweight both the long horizon and his unusually strong incentives to be personally involved if SpaceX gets anywhere near crewed Mars capability. I would still keep the probability well below certainty because a mission failure or a change in his health could easily spoil the outcome, but the fair number is much closer to the mid-50s than the low teens.
