SpaceX conducts its first Starship orbital test on or before September 22, 2026.

Question

Six frontier AI models put this at 25% by 27 Sept 2026. Full reasoning from every model.

WillHappen.ai · Accepted Answer

25% — the median of 6 frontier models, resolving by 2026-09-27.

Answer

Gemini (Google): 32% — Hitting a target date two days away requires flawless prep, zero technical scrubs, and cooperative weather on the exact attempt. First-of-kind or major upgrade Starship tests face high scrub rates at T-0, with historical maiden and profile tests slipping days. SpaceX must clear final FAA airspace notifications and wet dress rehearsals, where any ground-system abort pushes past September 22. A successful static fire or final FAA launch license issuance confirming propellant loading today would raise odds above 60%.

Answer

Claude (Anthropic): 18% — Hinges on whether Starship has already reached true orbital velocity by Sept 22, 2026, not just suborbital hops. SpaceX has historically slipped Starship milestones by months to years versus announced dates, so schedule risk is high. As of the resolution window, no confirmed fully orbital Starship flight has occurred; recent flights have been suborbital test trajectories. A last-minute successful orbital-velocity flight in the next week would flip this, but no public signal points to imminent readiness.

Answer

GPT (OpenAI): 86% — A Sept. 22 target is credible only if launch licensing, range availability, and vehicle readiness are already closed out. SpaceX must complete vehicle processing and obtain FAA/range approval within days; a scrub can readily push past Sept. 22. Starship has flown orbital-class test missions before, so this is not a first-ever capability milestone; near-term targets often slip days or weeks. Confirmation of a completed static fire, issued launch advisory, or FAA license by Sept. 21 would sharply raise the odds.

Answer

Grok (xAI): 38% — Whether the Sept 22 window survives a 48-hour weather/tech/range hold. SpaceX must stack, fuel, and get FAA/range go by 22 Sep; any anomaly after 20 Sep slips past the date. Historical first-attempt Starship/IFT dates slipped >50% of the time by days to weeks. A clean static-fire and no range conflict today would be the main thing that would raise the odds.

Answer

DeepSeek (DeepSeek): 12% — Whether SpaceX gets an FAA launch license and a clean static fire in the next 48 hours. SpaceX has never flown Starship to orbit; all flights to date were suborbital, so an orbital insertion by Sept 22 would be a first. The FAA license for an orbital profile requires a completed mishap investigation and environmental review, neither of which is confirmed done. A single static fire anomaly or range conflict would push the attempt past the window, as happened repeatedly in 2023-2025.

Answer

Qwen (Alibaba): 3% — Starship has never reached orbit; a first orbital test in 2 days from a standing start is essentially impossible. SpaceX's Starship program has conducted suborbital test flights but no orbital insertion as of late 2025; orbital flight requires FAA licensing, vehicle readiness, and… The context says 'targeted for September 22, 2026' but a target date is not a commitment—Starship development has slipped repeatedly, and no credible reporting confirms… Even if a launch were scheduled, orbital test flights require a full vehicle stack, propellant load, and trajectory that SpaceX has not yet demonstrated; base rate for…
