"Jacob Coxon said there is a 10 percent chance of AI causing human extinction within a decade"
Misattributed. Jacob Coxon's post of 8 September 2026 says the companies are gambling with our lives and carries no number; the greater than 10 percent within the next decade figure is Evan Hubinger's, Anthropic's alignment science lead, written in reply on 9 September. Senator Hawley's letter of 9 September attributes the figure to three Anthropic researchers without naming them. Attribute the number to Hubinger, dated 9 September.
The verdict
Absent
The ledger searched and found no instrument. The record says where it looked and when.
Where the ledger looked: On 16 September 2026 this ledger read TIME (9 September), Fortune (9 September) and NBC News (9 September) accounts of Jacob Coxon's resignation post of 8 September 2026 and his Slack message, and Senator Hawley's letter of 9 September as published on hawley.senate.gov. None quotes a percentage from Coxon. Fortune and TIME quote Evan Hubinger, Anthropic's alignment science lead, replying on X that he personally puts the chance above 10 percent within the next decade, and Fortune links his post (x.com/EvanHub/status/2097497037956891126), which refused a scripted fetch. Hawley's letter attributes the figure to three Anthropic researchers and names none. No statement by Coxon carrying a percentage was found.

What it changes
For a reader who has to repeat this claim
Give the number its author. Evan Hubinger, who leads alignment science at Anthropic, wrote on 9 September 2026 that he personally puts the chance of AI killing all humans above 10 percent within the next decade; he wrote it in reply to Jacob Coxon's resignation post of 8 September, which carried no figure. If you cite Senator Hawley, say his letter attributes the figure to three unnamed Anthropic researchers. Coxon said the industry is gambling with our lives; he did not say ten percent.
