# Current state
Blue Origin's Blue Moon MK1 ("Endurance") has completed thermal vacuum testing and is at Kennedy Space Center undergoing RF compatibility testing as of May 2026. SpaceX Starship has not yet completed the orbital propellant transfer demonstration required before any lunar landing attempt. The question resolves Yes only if Blue Moon MK1 touches down on the moon *before* an uncrewed Starship lunar landing AND before Jan 1, 2030.

# Event
Will Blue Origin land an uncrewed Blue Moon MK1 lander on the moon before SpaceX lands an uncrewed Starship, both before Jan 1, 2030?
# Outcomes to forecast
- **Yes**: Blue Moon MK1 lands on moon first AND before 2030
- **No**: Starship lands first OR neither lands before 2030
# Kalshi market anchor
**Current YES price: 54%** | +2% (7-day) | −6% (30-day) | Range over 89 days: 44–73% | Avg daily volume: 366 contracts. Market has drifted down ~19pp from its high, stabilizing near 54%.
# Sub-question answers
1. **Blue Moon MK1 schedule?** — Originally 2024, delayed to 2026. As of May 2026, MK1 is at KSC for RF testing; Blue Origin says landing possible "as soon as" 2026 but contingent on remaining tests and New Glenn return-to-flight. [Space.com, NASA]
2. **Starship uncrewed lunar landing timeline?** — Internal SpaceX doc targets June 2027 uncrewed lunar landing, contingent on propellant transfer demo (not yet done as of May 2026). [Space.com/Politico, Wikipedia]
3. **Does market count standalone Starship moon landing or only Artemis HLS?** — Rules say "SpaceX lands an uncrewed Starship" with no Artemis restriction; any uncrewed Starship lunar touchdown would count, but in practice the only credible path is via Artemis HLS.
4. **Technical milestones remaining?** — MK1: RF testing, New Glenn return-to-flight clearance (FAA investigation pending), launch & landing. Starship: propellant transfer demo (~10 tanker launches needed), design certification review, uncrewed lunar mission. [Wikipedia, Space.com]
5. **Base rate for lunar lander timelines?** — Historically, commercial/government lunar lander programs slip 2–4+ years. MK1 already slipped ~2 years from 2024. SpaceX Starship has "failed to meet many optimistic schedule goals." [Wikipedia]
# Key facts (high-confidence, factual)
1. [NASA] MK1 "Endurance" completed thermal vacuum testing at JSC; moved to KSC for RF testing as of May 2026.
2. [Space.com] New Glenn grounded pending FAA investigation into second-stage failure — key risk for MK1 launch.
3. [Wikipedia/Starship HLS] Starship propellant transfer demo not completed as of May 2026; ~10 tanker launches required before lunar attempt.
4. [Wikipedia/Artemis] Artemis III (2027) now a LEO docking test; crewed landing Artemis IV targeted 2028.
5. [Wikipedia/SpaceX Starship] Starship has launched 12 times as of May 27, 2026; 5 failures including all four Block 2 upper stages in 2025.
6. [Wikipedia/Blue Moon] MK1 originally planned 2024 landing, delayed to 2026.
# Cross-market signals
- **Kalshi – Starship docks before 2028**: 53% (−10% in 30 days) — docking is a *prerequisite step* to lunar landing; market is near coin-flip, suggesting refueling/docking milestone itself is uncertain by 2028.
- **Kalshi – Starship to Mars before 2030**: 15% — market prices Starship's ambitious milestones conservatively.
- **Kalshi – Next country to send humans to Moon (USA)**: 62% — consistent with 2028 crewed landing scenario.
- **Polymarket**: No directly relevant markets found.
# Analyst opinions and speculation
- Space.com (late 2025): "Blue Moon MK1 hitting lunar landing within months would give Blue a competitive edge, as SpaceX is nowhere close to a lunar landing."
- Yahoo Finance (May 2026): Blue Origin rocket explosion headline suggests New Glenn grounding is a real near-term threat.
- Internal SpaceX timeline (Politico): June 2027 for uncrewed Starship lunar landing — optimistic given propellant demo still pending.
# Directional lean per outcome
- **Yes (Blue Moon MK1 first):** MK1 hardware is further along (at KSC, post-TVAC); Starship faces more prerequisite steps; Blue Origin's ~1-year lead in readiness is real. BUT New Glenn grounding is a serious risk; Blue Origin has history of delays.
- **No (Starship first or neither before 2030):** Starship's uncrewed lunar target is 2027, leaving ~2.5 years of margin. If New Glenn delays MK1 into 2027–2028, race is close. "Neither before 2030" is also possible given both programs' slip histories.
# Gaps / unknowns
- New Glenn FAA investigation timeline and return-to-flight date (critical for MK1)
- Whether SpaceX propellant transfer demo will occur in 2026 as targeted
- Whether any standalone (non-Artemis) Starship lunar mission is planned
- Budget/political risk under changing NASA priorities
# Calibration anchors
- **Kalshi anchor: 54% Yes** (Blue Moon first)
- Blue Moon MK1 has ~12–18 month hardware lead over Starship for lunar landing readiness, but launch vehicle risk (New Glenn) partially offsets this
- Aerospace lunar programs historically slip 2–4 years; both vehicles have precedent for delays
- Starship docking market at 53% for pre-2028 suggests propellant transfer (prerequisite) is itself uncertain, supporting Blue Moon's relative advantage
