Interest in shares of private space companies such as Blue Origin, Sierra Space and Axiom Space has grown after SpaceX listed, but access for individual investors remains limited. In the United States, buyers typically must qualify as accredited investors and meet high minimum investments, with trading often conducted on secondary platforms. Prices are often indicative bids rather than firm market quotes. Deals can take 30 to 90 days, sometimes longer, and fees and lockups can be significant.

Pouch-type batteries are drawing renewed interest in defense and robotics as battery companies expand beyond slowing EV demand into sectors such as energy storage. The format offers high energy density and design flexibility but has faced concerns about rapid heat transfer between cells during thermal runaway. With all-solid-state solutions still years away, competition is shifting to external safety materials such as thermal barriers. Demand is also emerging from submarines and robots, though high material costs remain a hurdle for mass adoption.
