The orbiting ISS or at least the US segment of it, was designated a US National Lab in 2005. A few companies have research or commercial projects, including Made In Space's work on ZBLAN ultra-clear optical fiber https://madeinspace.us/capabilities-and-technology/fiber-optics/ https://madeinspace.us/capabilities-and-technology/fiber-opt... And Budweiser (a American beer subsidiary) has sent four experiments to the ISS on barley germination and malting https://www.issnationallab.org/blog/budweisers-fourth-investigation-spacex-crs19/ https://www.issnationallab.org/blog/budweisers-fourth-invest... While it's not turning a profit (ISS running costs are ~$3B/year) it is researching American space technology and agriculture for us down here on Earth. https://www.nasa.gov/mission_pages/station/research/nlab/index.html https://www.nasa.gov/mission_pages/station/research/nlab/ind...
