Thiel said he encouraged the person under discussion to write his book and supported him financially when he ran for the Senate in 2022.

The person discussed should be identified from the context of the interview (most likely JD Vance and his book 'Hillbilly Elegy'). There are two parts. (1) Thiel encouraged him to write his book. (2) Thiel gave financial support to his 2022 Senate run, either directly or through a supporting super PAC, as shown in FEC filings. True: a record shows Thiel made the statement around 2026-09-25, FEC or similar records confirm the 2022 financial support, and the book encouragement is backed by the author's own account, the book's acknowledgments or reliable reporting, or at least is not contradicted. Mostly true: both parts hold but a minor detail is off, such as the form or exact year of the support. Mixed: one part is confirmed and the other is contradicted. Mostly false: the support existed but not for the 2022 Senate race, or the role is substantially overstated. False: records show no Thiel financial support for that 2022 campaign and no encouragement of the book, or Thiel did not make the statement.

   “While Thiel notably opted against funding Vance in the general election in the increasingly red state, his $15 million donation to a pro-Vance super PAC helped the candidate emerge from a crowded GOP primary to replace the retiring Republican Sen. Rob Portman.”

   “In July 2021, Vance made the leap to politics when he announced his campaign for the U.S. Senate representing Ohio. Thiel bankrolled the run with $15 million.”

   “The billionaire investor Peter Thiel – who once answered a question about his interest in anti-ageing blood transfusions with the words ‘I am not a vampire’ – doesn’t appear in the book, though he’s listed in the acknowledgments.”

CNBC reports that Thiel gave $15 million to a pro-Vance super PAC during JD Vance's 2022 Ohio Senate primary (E1); LGBTQ Nation says Thiel bankrolled the run with $15 million (E2), and Mother Jones says he put $15 million into the 2022 Senate campaigns of Vance and Blake Masters, without separating the two (E3). The criteria count support through a super PAC. On the book, E4 says Thiel is listed in the acknowledgments of Vance's book. That does not directly show he encouraged Vance to write it, but it is consistent with the claim, and none of the evidence contradicts it, which is all the criteria require for this part. No evidence was given that records the statement itself or suggests Thiel did not make it.
