Humans land on the Moon again before 2030.

Question

Six frontier AI models put this at 49% by 16 Sept 2031. Full reasoning from every model.

WillHappen.ai · Accepted Answer

49% — the median of 6 frontier models, resolving by 2031-09-16.

Answer

Gemini (Google): 42% — Success hinges on SpaceX completing Starship orbital refueling tests and human-rating the HLS lander before Artemis slips past 2029. NASA Artemis III already faces immense schedule pressure from Starship HLS refueling flights and Axiom spacesuit readiness. China's Long March 10 and Lanyue lander aim for 2029-2030, but first-iteration crewed deep space architectures routinely slip 2+ years. A successful uncrewed Starship lunar landing demonstration by early 2028 would sharply increase odds of hitting the 2029 window.

Answer

Claude (Anthropic): 25% — Turns on whether Artemis III's HLS Starship lander clears its remaining technical hurdles before 2030. Artemis III is currently targeted for mid-2027 but has slipped repeatedly and Starship HLS still needs orbital refueling demos, uncrewed landing test, and lunar-ready… NASA programs of this complexity historically slip 2-4+ years past initial target dates, and this schedule has almost no margin left before 2030. China's own crewed lunar landing target is 2030, not earlier, so it's unlikely to beat or replace Artemis as the resolving mission within this window.

Answer

GPT (OpenAI): 63% — Artemis III’s landing-system and schedule execution, rather than stated target dates, will decide this. NASA must complete Artemis II, certify Starship HLS, and launch Artemis III; its official target has repeatedly slipped from 2024 to 2027. China’s stated 2030 crewed-landing goal provides an independent path, but it still must prove new rockets, lander, and operations. I would raise this sharply after a successful uncrewed HLS lunar landing and Artemis II, or after China flies its new crew vehicle and lander.

Answer

Grok (xAI): 58% — Artemis III must fly a crewed Starship HLS landing by Dec 2029 after remaining uncrewed demos. NASA/SpaceX must complete two uncrewed HLS landings plus Orion/SLS integration; each historically slips 12-18 months. Base rate of crewed lunar programs since Apollo is zero successes inside original windows; China targets 2030 so adds little pre-2030 probability. A successful uncrewed HLS landing in 2027 would raise this sharply; another HLS or SLS failure would drop it below 30.

Answer

DeepSeek (DeepSeek): 55% — Whether Starship HLS refueling and China's Long March 10 both stay on track through 2029. NASA's Artemis III slipped to 2027+ on Starship HLS delays; no crewed landing since Apollo 17 in 1972 gives a 50-year base rate of zero. China targets 2030 with Long March 10 and a new lander, but its program has never flown crew beyond LEO, so the window is tight. One orbital Starship refueling demo succeeding in 2027-2028 is the single development that would move this sharply upward.

Answer

Qwen (Alibaba): 38% — Starship HLS must complete uncrewed lunar demo and propellant transfer before any crewed Artemis III attempt. Artemis III slipped to mid-2027 at earliest; Starship has not yet done orbital refueling or uncrewed lunar landing demo. China's crewed lunar landing targets 2030 with Long March 10 still in development; no precedent of first-try crewed lunar landing. Would move up sharply if Starship completes a successful uncrewed lunar landing demo by mid-2027.
