Meta filed the most lobbying disclosures among the big‑tech AI firms for the third quarter of 2026, according to federal records. OpenAI and Anthropic also reported meetings with lawmakers about how AI labs can share security‑related information without breaking antitrust law. Anthropic singled out a bill called the Collaboration on Adversarial Threats and Security Risks Act, which would let labs coordinate on safety risks. OpenAI listed a broader focus on AI‑security collaboration and possible antitrust protections. The filings do not say whether the companies supported or opposed the proposals.

## The facts

- Meta topped big‑tech AI lobbying in Q3 2026
- Anthropic cited the Collaboration on Adversarial Threats and Security Risks Act

## Why it matters
