Blender has USD support, but I think it would be difficult for them to contribute to OpenUSD directly. They're more of an "downstream user".

It's similar to SideFX and Houdini, which is an extremely common way to author USD scenes. SideFX isn't a member either, just a downstream user.

SideFX are a member. They’re listed on the main site under General Members.

Should have looked first. Blender should buy in at that level too.
