Kalshi traders doubt SpaceX will achieve human Mars missions this decade

1 hour ago 2



The Red Planet isn’t going anywhere. And according to prediction market traders, neither are humans, at least not before the end of this decade.

Kalshi, the regulated prediction market platform, is currently pricing the probability of SpaceX launching humans to Mars via Starship before the end of 2029 at just 18-21%. A separate but related contract asking whether SpaceX can land anything on Mars before 2030, crewed or not, sits at roughly 29-31%, with the Yes side trading around 29 cents on approximately $70,000 in total volume.

The gap between ambition and execution

Musk has never been shy about setting aggressive Mars timelines. Previous public statements from the SpaceX CEO targeted uncrewed missions to Mars by late 2026 and crewed efforts shortly thereafter. The vision of a self-sustaining human settlement on Mars by the late 2020s has been a recurring theme in Musk’s public appearances and social media posts for years.

None of these timelines have been confirmed publicly. SpaceX does not currently have an official schedule for human missions to Mars, which is precisely the kind of detail that makes prediction market traders nervous.

A flyby is not a landing

Adding an interesting wrinkle to the Mars conversation, SpaceX announced in May 2026 that Chun Wang, a cryptocurrency billionaire and co-founder of Bitcoin mining pool F2Pool, will lead a private crewed Starship flyby mission around Mars. Wang reportedly controls roughly 11% of Bitcoin’s hashrate through his mining operations, making him one of the most influential figures in crypto infrastructure.

The key word in that announcement is “flyby.” The mission does not plan to land on the Martian surface. No launch date has been specified for Wang’s mission.

What this means for investors watching the space

The low probabilities on Mars-related contracts suggest that sophisticated traders see significant technical, regulatory, and logistical hurdles remaining between where Starship is today and where it needs to be for interplanetary missions.

For the broader crypto market, there are no notable crypto-native platforms or tokens directly tied to these Kalshi prediction market contracts. Wang’s involvement as a crypto industry heavyweight adds a narrative thread connecting the two worlds, but his participation in a Mars flyby mission doesn’t create direct price implications for Bitcoin or any other digital asset.

With roughly $70,000 in volume on the Mars landing contract, these markets are still relatively thin compared to Kalshi’s more popular political and economic contracts. That means prices can be somewhat volatile on small order flow, and the current odds should be read as directional indicators rather than precision instruments.
