“OpenAI gave lip service to AI regulation at the US Senate; Anthropic actually supports regulation.”
Our reading:
OpenAI gave only lip service to AI regulation at the US Senate, while Anthropic actually supports regulation.
Assessment: Unresolved
What happened
Was it true for the period described?
Outcome: Unresolved
We checked, and the evidence so far doesn’t settle it.
Judged on a plain reading. They named no measure, so we used the reading a typical informed reader would take. It is spelled out under “How we judged it”.
Evidence up to . Checked .
Why
Anthropic's endorsement of SB 53 supports its half of the comparison. OpenAI's opposition to SB 1047 shows a concrete disagreement over state regulation, but the same letter records support for federal initiatives. That record does not establish that its Senate position was merely lip service. It also does not establish that its later advocacy delivered the substantive safeguards described to the Senate. The combined claim remains unresolved.
Caveats
- Public advocacy establishes positions more readily than sincerity.
- Support for voluntary standards or narrower legislation is not automatically equivalent to support for binding frontier-model safety requirements.
- Later policy changes cannot determine what was true when Marcus posted.
Evidence (3 items)
Supports the claim: Anthropic,
Anthropic is endorsing SB 53, the California bill that governs powerful AI systems built by frontier AI developers like Anthropic.
Why it matters: This directly supports the Anthropic component. The endorsement concerns binding requirements applicable to the company, rather than a general statement favoring safety.

Licensees could be required to perform pre-deployment risk assessments and adopt state-of-the-art security and deployment safeguards.
Why it matters: The Senate follow-up describes possible mandatory safeguards for licensees. It establishes the substance against which later advocacy should be compared, but cannot establish whether the commitment was sincere.

We will continue to work with federal stakeholders and other industry leaders to advance a clear set of AI policies.
Why it matters: The letter opposes SB 1047 while recording endorsement of the Future of AI Innovation Act and a preference for federal regulation. This documents selective opposition and supplies material counterevidence to a blanket reading of 'lip service', without settling whether the proposed federal measures fulfilled the Senate commitment.

- None given. We don’t add one.
Where we had to interpret
- I read 'lip service' as a claimed gap between OpenAI's stated support for regulation and its substantive regulatory advocacy. Opposition to one bill does not by itself establish that gap.
- I read Anthropic's 'actually supports regulation' as support for concrete, binding AI rules, including rules applicable to itself.
- The Senate reference is interpreted as the May 2023 hearing and its follow-up record. The comparison concerns subsequent conduct through the post date.
- Regulatory advocacy has no quarterly reporting period. The target period therefore covers the referenced Senate episode through February 8, 2026; later changes in policy do not settle this historical comparison.
Right if: The record shows that OpenAI's regulatory advocacy substantially failed to follow through on its Senate commitments, while Anthropic advocated concrete, binding AI regulation. Selective disagreement with legislation is insufficient by itself.
Wrong if: The record shows substantive OpenAI advocacy implementing the regulatory commitments at issue, or shows that Anthropic's claimed concrete support did not occur. Evidence against one component would not erase evidence supporting the other.
We wrote this test after the outcome was known.
What would settle it
A fuller contemporaneous record of OpenAI's proposed binding requirements and legislative interventions, tied to its Senate commitments, could establish substantive follow-through or a sustained effort to defeat those same safeguards.
