Will Elon Musk visit Mars in his lifetime?

The core issue is not whether Mars becomes reachable in the abstract, but whether Elon Musk personally makes the trip before 2099. Musk is wealthy enough, influential enough, and strategically aligned with Mars colonization that he could strongly motivate a mission if the technical path becomes viable. Over a 73-year window, even events that look remote today can become plausible if SpaceX or a successor achieves routine deep-space transport and Musk remains sufficiently healthy and willing to go. That keeps the probability meaningfully above zero, and his repeated public emphasis on Mars makes this more than a vanity bet on a casual dreamer.

Against that, the bar is extremely high. He would need not just a successful Mars mission, but one that includes him personally, at an age when ordinary mortality, medical screening, and mission risk become major constraints. The first crewed Mars missions are likely to be dangerous, delayed, and politically or commercially constrained; even if humans land on Mars in the 2030s or 2040s, there is no guarantee the inaugural or early crews will include Musk. His role as founder, executive, or funder does not translate into actual travel, and he may have more leverage and utility on Earth than as a passenger on a high-risk interplanetary mission.

The market at 11% looks somewhat low to me, though not wildly so. I think the market may be over-weighting the health, age, and mission-risk objections while under-weighting the enormous amount of time remaining and Musk’s unusual willingness to pursue extreme, identity-defining goals. Still, this is not a strong yes: the dominant outcome is that Mars arrives too late, proves too dangerous, or happens without Musk aboard.
