Will Elon Musk visit Mars in his lifetime?
I put this at 7%, below the market, because the event requires not just a successful human Mars program but Elon Musk personally surviving long enough and choosing to be on an early mission. That is conceivable, but the stack of conditions is unusually demanding.
Analysis
The core issue is that this is a personal-appearance event, not merely a question of whether humans reach Mars. For Yes to resolve, Musk must still be alive, physically capable, and willing to travel on a Mars mission after a long chain of technological, regulatory, and operational breakthroughs. SpaceX gives this some credibility because Musk has both the motive and the means to push hard for Mars, and he has repeatedly framed Mars as a personal mission rather than just a business objective. If crewed Mars flight becomes real, he is one of the few people who might actually insist on going.
Against that, the probability compounds multiple low-probability hurdles. Musk would need to remain alive into a window when Mars transport exists, which is already uncertain even before considering the hazards of interplanetary travel. A first Mars landing is likely to be dominated by safety, political, and operational caution, and founders are not automatically the people selected for the highest-risk seat. Even if SpaceX reaches Mars eventually, the most plausible early pattern is that Musk supports the program from Earth while younger astronauts handle the actual landing.
Relative to the market’s 11% price, I think the market is a bit optimistic. Eleven percent is defensible only if one assigns a very high chance to both Musk’s longevity and his personal participation in a first-wave Mars mission, and I think that overstates the odds. The market may be anchoring too much on Musk’s stated desire to go to Mars and not enough on the practical reality that this is a bet on extraordinary technical success plus personal survival plus voluntary exposure to risk.
Arguments
For
- Elon Musk has repeatedly expressed a strong personal desire to go to Mars, making this more plausible than for most executives.
- If SpaceX achieves a successful Mars transport system, Musk could choose to be on an early mission rather than merely observing from Earth.
Against
- The event depends on Musk remaining alive and healthy for decades, which is a major constraint even before considering spaceflight risks.
- Early crewed Mars missions are likely to be highly risk-managed, and the first astronauts may be chosen for operational reasons rather than symbolism.
Key drivers
- Musk’s age and survival through the likely timeline for any crewed Mars program.
- Whether SpaceX or another system reaches a safe, human-rated Mars landing in time.
- Whether Musk would be willing and able to take one of the earliest seats himself.
Risk factors
- A breakthrough in long-duration human spaceflight could make a Mars trip feasible sooner than expected.
- Musk has exceptional influence over SpaceX and could prioritize his own participation if the opportunity arises.
Scenarios
Best case
SpaceX or another system makes crewed Mars travel routine within Musk’s lifetime, and Musk chooses to join an early mission, making the event resolve Yes.
Most likely
Human Mars travel eventually becomes possible, but Musk either does not live long enough or is not among the people who actually visit, leading to No.
Worst case
Crewed Mars travel is delayed, Musk dies before any opportunity arises, or he never goes despite the program succeeding, so the event resolves No.

Will Anthropic flip BTC by December 31?
AI2%MKT77%Edge-75HypedAnthropic flipping Bitcoin by the end of 2026 looks extraordinarily unlikely. The valuation gap is so large that it would likely require a once-in-a-generation private funding event for Anthropic and a major Bitcoin drawdown at the same time.

"Spider-Man: Brand New Day" total domestic gross by August 31? (Higher Strikes)
AI25%MKT84%Edge-59HypedMy read is that Spider-Man: Brand New Day is more likely to finish above 900M domestically by August 31 than below it. I put the chance of less than 900M at about 25%, because the film is already so far along that only an unusually sharp slowdown would keep it under the line.
