Jacob Coxon, the 27-year-old former Anthropic researcher who warned that OpenAI and Anthropic were racing toward self-improving superintelligence and "gambling with our lives," was working with a communications firm linked to prominent AI-safety advocates while that warning went public, an investigation published on September 24 reported. The same day, he told a television interviewer that no third party was involved.

The warning had a booker

Jacob Coxon said he went public alone. Two people familiar with the matter, and a September 9 email, say a firm that represents leading AI-safety advocates was arranging interviews as he did.

Stated risk, drawn to scale

Greater than 1 in 10 within a decade

>10%

one block = 10%

An Anthropic alignment lead said the chance AI kills everyone within ten years is greater than 10 percent. The orange block is that floor. The pale blocks are not a forecast of safety.

Takeaway: a personal lower bound from inside the lab, not a measured probability and not a claim about today's models.

Coxon and the firm do not immediately comment.

What holds up

The fear can still be real

He calls himself a doomer if that means extinction unless the industry changes course. A colleague still at Anthropic publicly agreed the risk is serious. Professional help does not, by itself, prove the warning was staged.

What does not match

The denial and the calendar

He said no third party was involved on the same day an email sought to book him. He is not on the firm's public client list, and nobody has said who paid.

Still open

Who paid for the booking?

The arrangement is reported, not confirmed by either side. Three limits sit on the claim.

Not listed. Coxon is not a public client of the firm.
No reply. He and the firm did not immediately comment.
Same day. The email that was reviewed is dated September 9.
