Doesn't matter. They'll get enough DoD contracts and other sources of funding to keep them alive because certain parties (rightfully) have a strong interest in domestically retaining this sort of specialty engineering capability.
Sounds like they haven't (yet).
And that's where the money will come from. A dozen units here and there pays the bills when you're making super high margin stuff in barely higher than prototype volume.
I used to follow this stuff closely. Back in the 1990s I figured out how to do slip control for legged running across rough terrain, which requires something like "ABS for legs" to control slip. I have a patent on that, and that was used by the McGill legged robot in Canada. I was thinking high-end toys, like Aibo, or the humanoid Aibo that never came out as a product. But that market segment went nowhere. I could never see a business model for this. I met the designer of the Furby and found out what costs were like for that. No way were we going to get legged running down to toy pricing.
Today, you could probably build a good running robot toy today for the $2K Sony is charging for their new Aibo, if you could sell a few hundred thousand. The compute power required isn't that high. Big Dog runs on a Pentium-class machine running QNX, with the balance servo loop running at 100Hz and the hydraulic valve control loops running at 1KHz. Batteries and motors are way ahead of where they were in the 1990s. Boston Dynamics' new smaller robots finally got rid of the hydraulics. All this is much easier to do than it used to be.
When Google bought all those robotics companies, I thought big things were going to happen. Then we didn't hear anything for years. People in robotics thought they must have a big secret project underway. Turned out that Google had no clue what to do with all that robotics expertise. Maybe Softbank will come up with something.
