This market resolves when the first crewed orbital space station or station module that generates artificial gravity through continuous rotation becomes operational, with a crew aboard experiencing sustained partial or full gravity produced by that rotation.

Eligible systems include rotating habitats, wheel stations, torus stations, or centrifuge modules large enough to support normal crew habitation for extended stays. The rotation must be the primary means of generating gravity for at least part of the habitable volume.

The market resolves to the country or region of the organization primarily responsible for developing and operating the station or module. If responsibility is genuinely shared between organizations from multiple listed options, the market resolves to "Other".

Does not count

• Short-duration centrifuge experiments on otherwise microgravity stations (e.g. a small centrifuge aboard the ISS or another station).

• Ground-based rotating facilities or simulators.

• Uncrewed demonstrators or test articles.

• Spacecraft that generate artificial gravity only during transit and are not orbital space stations.

If no qualifying artificial-gravity space station has become operational by that date, the market resolves to "No artificial-gravity station launched by resolution date."

Current context

As of mid-2026:

Vast has stated that it intends to pursue a rotating habitat after Haven-1 and Haven-2, but not before the 2030s.

Orbital Assembly Corporation has proposed the rotating Voyager Station concept, though the project has experienced repeated delays.

Russia's RSC Energia has patented a rotating artificial-gravity station concept (~0.5 g), but no funded development program or launch schedule has been announced.

No government agency or private company has announced a confirmed launch date for a qualifying artificial-gravity station.
