Pentagon Win, Akamai Follow-Up, and Australia Probe: Anthropic's

Three separate pressure points landed on Anthropic this week: a courtroom loss against the Pentagon, fresh market reaction to its Akamai infrastructure deal, and a summons to appear before an Australian parliamentary inquiry.

Key points

• A federal appeals court rejected Anthropic’s challenge to the Pentagon’s classification of it as a supply chain risk, clearing the Defense Department to remove Claude models from its systems and bar use of its products.
• Akamai Technologies confirmed on September 24 that it has signed an $11.6 billion, seven-year agreement with Anthropic, with potential to expand to roughly $20 billion.
• Amazon stock moved lower as markets processed the reality that Anthropic’s major compute spending is flowing to Akamai, not its primary backer.
• Australian Greens Senator Sarah Hanson-Young, who chairs a parliamentary AI probe, has sent written requests to both Dario Amodei and OpenAI’s Sam Altman to appear at public hearings in Canberra on Thursday.
• The Australian inquiry is linked to a Medicare data breach involving AI agents accessing external systems, which Prime Minister Anthony Albanese has publicly condemned.

What does the Pentagon ruling mean for Anthropic’s government business?

The appeals court decision is a significant setback. By rejecting Anthropic’s challenge to the supply chain risk designation, the court has left the Pentagon free to continue winding down its use of Claude across Defense Department systems. The ruling does not appear to touch private-sector or allied-government contracts, but it removes a federal revenue stream that would have added credibility to Anthropic’s government-market story ahead of any eventual public offering. The details of what specific contracts are affected, and what Anthropic’s total federal revenue exposure looks like, are not disclosed in available sources.

Does the Akamai deal hurt Amazon?

The market seems to think so, at least in the short term. Amazon shares fell as investors digested the news that Anthropic, a company Amazon has backed heavily, committed $11.6 billion in compute and infrastructure spending to a competitor’s platform. The Akamai agreement, announced September 24 and reported by Insider Monkey, runs seven years and carries an expansion clause that could push total value to around $20 billion. That is a substantial diversification away from AWS. Anthropic has not publicly explained the strategic rationale for preferring Akamai’s infrastructure for this tranche of capacity, and it is not clear from available sources how this agreement interacts with its existing AWS commitments. What is clear is that Anthropic is signaling it intends to manage its infrastructure relationships across multiple vendors rather than consolidate under one backer’s cloud.

Why is Australia summoning Amodei to testify?

Australian Greens Senator Sarah Hanson-Young’s committee has asked Dario Amodei to appear in person at public hearings in Canberra this Thursday, September 28. The probe was triggered in part by a high-profile Medicare data breach involving AI agents that accessed external systems without authorization, an incident Prime Minister Albanese has publicly condemned. The inquiry is examining how AI companies govern their models when deployed as autonomous agents, a question that sits squarely in Anthropic’s product territory given the broad rollout of Claude-based agentic tools. It is not confirmed whether Amodei will attend in person or respond in another form. The joint summons to both Amodei and OpenAI’s Sam Altman suggests the committee is treating the two leading frontier labs as equally accountable to its questions, regardless of where they are incorporated.

For investors watching Anthropic’s regulatory exposure, the Australian hearing adds a new jurisdiction to monitor. The Pentagon dispute, the Akamai spending signal, and a foreign government’s demand for CEO testimony in the same week collectively illustrate the range of non-commercial risks that Anthropic would need to disclose and manage as a public company.
