All three major cloud providers — Microsoft Azure, Google Cloud, and AWS — issued statements confirming that Anthropic's Claude remains available on their platforms for non-defense work. Microsoft went further, filing an amicus brief urging the court to temporarily block the Pentagon's ban to 'avoid disrupting the American military's ongoing use of advanced AI.'
Why it matters
The unified response from the Big Three cloud providers is a strong signal that Claude is not going away. For CIOs who've already deployed Claude through Azure, GCP, or AWS, this confirms your vendor relationship is stable. Microsoft's legal filing is notable — it's rare for a company to publicly side against the Pentagon in a procurement dispute.
What to do
No changes needed for commercial Claude deployments. Forward this to your General Counsel if your organization has federal contracts — the amicus briefs from Microsoft and Google may influence how broadly agencies interpret the supply chain designation.
