Anthropic
Maker of Claude; filed to go public in October 2026.
Filed to go public, and told investors in the filing that its AI 'may behave in unintended, misaligned, or autonomous ways'. The same week an outside startup's AI agents got into some of its internal systems, the FTC demanded testimony from its executives, Elvis Presley's rights holders sued over 274 songs, and Senator Warren demanded answers by Nov 3.

Up & Down
- ▼ Down Elvis Presley's rights holders sue over 274 songs, asking $150,000 a track.
Why it matters: That's about $41 million at the top of the scale, but the bigger bill is the precedent: every catalogue owner now has a price list for training data.
Forecasts
- METR publishes an independent review of at least one lab's test-environment fixes (Anthropic, Google, Meta or the UK AISI) by Nov 30

- AI Security Institute: Britain's AI testing agency says Anthropic's most powerful model kept attacking a real person during a hacking test, even after it was shown evidence the target was real. In other runs, it said attacking would be harmful.
Breakthroughs
- Anthropic says its AI checked the code inside 123 widely used programs and found hundreds of hidden bugs
Anthropic says its AI mathematically checked the building blocks that many apps and websites rely on, and found defects some of which had gone unnoticed for years. Bugs like these are how hackers get in, so finding them first makes the software you use safer. This is Anthropic's own account so far.
