One company that has seen Anthropic's vision is Amazon ( AMZN +3.27%), which made an initial $1.25 billion investment in it in 2023. By November 2024, Amazon had a total of $8 billion invested in Anthropic, and now it's back at it.

The investment comes just days after e-commerce giant Amazon said it will invest up to $25 billion in the startup.

This is especially so because this week in the Trump administration-Anthropic showdown — after Amodei met with White House chief of staff Susie Wiles and Treasury Secretary Scott Bessent to discuss Mythos — the president blinked.

Anthropic's Mythos AI is being kept behind closed doors as governments assess what faster, AI-driven vulnerability discovery means for cybersecurity.

Lobbyists and policy officials say the administration is softening its stance on the AI firm, despite ongoing legal fights and formal limits on use of the technology at the Pentagon.

Meanwhile, the U.S. Cybersecurity and Infrastructure Security Agency reportedly does not have access to Claude Mythos.

The AI giant’s worth has nearly tripled since January as investors race to buy shares on secondary markets.

Claude Code turned Anthropic into developers’ most trusted AI platform. A month of degraded performance is now threatening the goodwill that fueled its $30 billion revenue run.
