Will Elon Musk visit Mars in his lifetime?
The chance that Elon Musk personally visits Mars before August 1, 2099 looks materially higher than the market implies, but still far from certain. A reasonable independent estimate is around 30%, driven by the combination of a very long time horizon and Musk’s unusually strong commitment to making Mars travel happen, offset by major technical, medical, and schedule uncertainty.
Analysis
The strongest case for Yes is that the time horizon is extremely long and Elon Musk has repeatedly made Mars the central ambition of SpaceX. Public reporting shows that the company is still pursuing Mars-capable Starship development, with near-term uncrewed missions first and crewed missions only after those tests succeed, which means the path exists in principle even if it is delayed. Over several decades, Musk may also remain financially, politically, and physically capable of participating in a mission if the program matures enough to carry humans safely.
The strongest case against Yes is that this is not a generic Mars question but a personal one about Musk himself visiting Mars, which adds major obstacles beyond launch capability. Current reporting still centers on uncrewed Starship flights and robots, while crewed Mars timelines remain speculative and have already slipped repeatedly from earlier promises. Even if humans reach Mars sometime in the 2028 to 2031 range, that does not automatically mean Musk will be on the first or any later crewed flight, and the odds decline further as age, health, corporate control, and mission risk accumulate.
Compared with the market’s 10% Yes price, the market looks somewhat too bearish if interpreted literally over a 75-year horizon. There is enough time for multiple development cycles, and a mission program that survives long enough could eventually include Musk, but the personal-risk layer makes this much less certain than a normal “will humans go to Mars” market. A fairer price is well above 10%, though not high enough to justify optimism; the market is probably underweighting the long runway while still correctly discounting the enormous execution risk.
Arguments
For
- Arguments for Yes: The date window is long enough that a delayed but successful Mars program could still happen while Musk is alive and willing to go.
- Arguments for Yes: Musk has repeatedly framed Mars as his defining goal, so personal participation would fit his long-running strategic and symbolic priorities.
Against
- Arguments against Yes: Current plans emphasize uncrewed Starship missions first, and there is still no confirmed human Mars flight schedule.
- Arguments against Yes: Even if crewed Mars missions begin, Musk personally boarding one is optional and may be avoided for safety, leadership, or health reasons.
Key drivers
- Musk’s long-standing and unusually persistent commitment to Mars makes a future personal trip plausible if the program succeeds.
- The remaining gap to safe, routine crewed Mars travel is still large, with uncrewed validation and key Starship milestones not yet proven.
Risk factors
- Musk may never choose to fly even if SpaceX reaches crewed Mars capability, since the event requires his personal visit.
- Age, health, mission safety, and the possibility of program delays or failure can all prevent a yes outcome despite the long time horizon.
Scenarios
Best case
SpaceX eventually demonstrates reliable Mars transport, crewed missions begin, and Musk chooses to join a later flight as a high-profile participant before 2099.
Most likely
SpaceX advances through uncrewed Mars testing and may eventually send humans, but Musk himself either never goes or only does so much later than current public timelines suggest.
Worst case
Starship never reaches a safe, operational Mars crew capability in time, or Musk never personally flies even if it does.

Starbucks total global stores in 2026
AI62%MKT15%Edge+47Hidden GemStarbucks is materially more likely than the market implies to finish 2026 above 41,800 total global stores. The combination of an already very large base and guidance for 600 to 650 net new global openings makes the threshold look attainable unless closures or execution slippage are unusually heavy.

US real GDP growth in 2036?
AI64%MKT20%Edge+44Hidden GemThe most likely outcome is moderate positive growth in 2036 rather than near-stagnation or a boom, with the center of gravity in the 1.6% to 2.5% range. The market looks somewhat compressed toward lower-growth outcomes, but not dramatically mispriced unless the contract is tied to a structurally faster-growing emerging economy.
