The Agent Stack #012 — Friday Signal


The biggest AI policy story this week wasn’t in Congress. It was in federal court, where Anthropic just won a preliminary injunction against the Pentagon’s attempt to blacklist them from government contracts.

Main Analysis

Here’s what happened: The Department of Defense added Anthropic to their “supply chain risk” list, effectively banning federal agencies from using Claude. Anthropic sued immediately, claiming the decision was arbitrary and violated due process.

A federal judge sided with Anthropic on Thursday, granting the injunction whilst the case plays out. This forces the Pentagon to rescind the restrictions temporarily.

Why this matters for agent builders: Government procurement drives massive enterprise adoption. When the Pentagon blacklists an AI company, other large organisations often follow suit. This injunction keeps Anthropic in the game whilst legal proceedings continue.

The timing is crucial. With David Sacks stepping down as AI Czar this week, there’s a power vacuum in White House AI policy. The Pentagon tried to fill it with aggressive restrictions. The courts just said no.

This sets precedent for how AI companies can challenge government restrictions. Expect more litigation as agencies try to regulate AI development through procurement rules rather than legislation.

Takeaway: If you’re building enterprise agents, don’t assume government restrictions are permanent. Legal challenges can work, and procurement policies shift faster than laws.

Quick Hits

Apple opens Siri to third-party AI: iOS 27 will let users choose which AI chatbot handles Siri queries - Google Gemini, Claude, or others downloaded from the App Store. Game changer for voice agent integration.

Harvey hits £8.6B valuation: The legal AI startup raised another round led by Sequoia at an £11B ($11B) valuation. That’s triple their previous round. Enterprise AI is still printing money.

Bernie and AOC want data centre moratorium: New legislation would halt all new data centre construction until Congress passes comprehensive AI regulation. Won’t pass, but signals growing political pressure.

One Thing to Try

Google just launched new import tools for Gemini that pull chat history and memory from other AI assistants. If you’re building agents that need to migrate user context between platforms, study how they’re handling data portability. The implementation could inform your own switching tools.

The Pentagon learned this week that blacklisting AI companies is easier than keeping them blacklisted.
