US-based company with the keys to literally every system on the planet is labeled a supply chain risk. Doesn't make sense.
Anthropic's motion for a stay has been denied by the D.C. Circuit.
This was essentially the D.C. Circuit equivalent of the motion for a preliminary injunction that they filed in California. What this means is that Anthropic will remain a designated supply chain risk for a while -- probably at least six weeks or so, possibly a lot longer.
This is not the worst-case "corporate murder" scenario; Anthropic has been designated a supply chain risk for more than a month now, and although they've lost some business they haven't been treating the desigation like an existential threat to their company. It's obviously not great for them, though.
The one bright spot for Anthropic is that the court expedited the schedule, so it looks like the case will be decided quite quickly -- the briefs are all due by early May, and oral argument is on May 19. So Anthropic will likely get a final decision not too long after that, at which point they can appeal to SCOTUS (or ask for the whole D.C. Circuit to review this panel's decision) if they lose.
Given that the merits will be heard so quickly, I sort of doubt that Anthropic will appeal this denial of a stay--they'll probably just wait to appeal the merits decision if they lose that.
