Well Axiom is contacted for adding 2 modules to the ISS so their Habitation modules are more or less financed by NASA so it mainly depends on if the research and power tower modules are built and docked.

NASA is providing partial development funding and paying for 2 astronauts constantly on orbit plus 200 experiments per year for the 3 that are part of the CLD program which is Orbital Reef, Starlab and NG’s station.

Orbital Reef and Axiom have already got some countries and private companies signed up to use their stations once they are up and running.
