Market context
SpaceX and Geometric Energy Corporation's Doge-1 mission aims to place a 12U CubeSat into lunar orbit, carrying Dogecoin blockchain nodes and sensors. The satellite requires a successful launch from a SpaceX facility by 31 December 2026 to resolve affirmatively; post-launch anomalies do not affect the outcome. The 54% implied probability reflects genuine uncertainty around launch scheduling and technical readiness rather than fundamental feasibility concerns.
Historical precedent suggests CubeSat lunar missions face material delays. NASA's Artemis I (December 2022) carried ten secondary payloads including lunar-bound CubeSats, though several experienced deployment complications. More directly comparable, commercial lunar lander missions—including Intuitive Machines' IM-1 (February 2024) and Firefly Aerospace's Blue Ghost—encountered multi-year slippages from initial target dates. Doge-1 was originally scheduled for 2021; the current 2026 window represents the third major revision. This pattern suggests the crowd's 54% reflects appropriate scepticism about execution timelines rather than technical risk.
Traders should monitor SpaceX's manifest updates and Geometric Energy's public statements regarding payload integration status. Recent industry reporting indicates SpaceX's manifest remains congested through 2025, with lunar-dedicated missions competing for rideshare slots. The Federal Communications Commission's approval of the mission's communications protocols (last updated 2023) remains valid, but any regulatory changes affecting CubeSat operations could trigger delays. Conditional order logic should track announced launch windows; even minor slips into Q4 2026 compress the resolution window significantly. Official SpaceX YouTube confirmation remains the definitive settlement source.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
