Peter Thiel has worn many hats over the years: Silicon Valley founder, Trump megadonor, cryptocurrency booster, democracy skeptic.

But there is yet another facet to Thiel, one that has remained secret until now: FBI informant.

In the summer of 2021, Insider has learned, Thiel began providing information as a “confidential human source,” or CHS, to Johnathan Buma, a Los Angeles-based FBI agent who specializes in investigating political corruption and foreign-influence campaigns. 

Charles Johnson, a longtime associate of Thiel’s and a notorious figure in the far-right movement that Thiel has subsidized for a decade, told Insider in a statement that he helped recruit the billionaire as an informant by introducing him to Buma.

A source with knowledge of Thiel’s relationship to the FBI, whose identity is known to Insider but who insisted on anonymity, corroborated Johnson’s account, telling Insider that Johnson brokered a relationship between Thiel and Buma. Insider was able to confirm through an additional source that the FBI added Thiel to its formal roster of registered informants.

Another source close to Thiel told Insider that while they could not confirm that Thiel was a CHS, Thiel did speak to Buma occasionally. The source said that any assistance Thiel might have provided to the FBI should be understood as part of Thiel’s gradual distancing of himself from Trump and the broader MAGA movement, which has vigorously criticized the FBI and other federal law-enforcement agencies.

Valuable information on a recurring basis

The FBI maintains a vast network of informants to keep tabs on organized crime, terrorist threats, extremist groups, and other criminal and intelligence targets. These sources, according to the bureau’s Confidential Human Source Policy Guide, are more than casual tipsters. 

Confidential human sources enter “into a relationship with the FBI, and that relationship will forever affect the life of that individual,” the guide says. “[They] will be either an ‘FBI source’ or a ‘former FBI source’ and, in turn, his or her conduct or misconduct will reflect upon the FBI.” As such, the process for recruiting and maintaining such sources is highly regulated, requiring multiple layers of approval. Only people who are able to provide “valuable information … on a recurring basis” are granted CHS status, according to the policy.

As a CHS, Thiel was assigned a code name and an internal serial number to track his reporting. The information he passed on about foreign contacts and Silicon Valley intrigue was reviewed and “validated,” or cross-checked against other sources, by his case agents and their colleagues.

Thiel did not respond to multiple requests for comment. A Thiel spokesperson stopped responding to inquiries after being told that Insider was reporting on Thiel’s relationship with the FBI. 

The FBI’s national press office and Scott Horton, an attorney who represents Johnathan Buma, both declined to comment.

No reporting on political ties

Thiel is a citizen of Germany, the United States, and New Zealand; as of last year,  he was reportedly in the process of acquiring yet another passport, from Malta. In 2016, he donated $1.25 million to Trump’s campaign and endorsed him from the stage at the Republican National Convention. After Trump won, Thiel served on his transition team.

Johnson, who said that he was also an informant for Buma, told Insider that he believes that Thiel’s reporting to the FBI was largely limited to foreign contacts and attempts by foreign governments to penetrate Silicon Valley. Thiel has publicly called on the FBI to investigate Google’s ties to the Chinese government.

Thiel, Johnson said, was directed by the FBI not to report on his interactions with Donald Trump or other US political figures.

Many of the politicians that Thiel has bankrolled — including Trump, Sen. J.D. Vance of Ohio, and Blake Masters, a former Arizona senatorial candidate — have repeatedly attacked the bureau and its leadership in public. In 2022, Vance, whose campaign and affiliated PACs received a total of $15 million from Thiel, falsely claimed that the FBI had illegally wiretapped Trump’s phone. Vance accused the bureau of “harassing faithful Christians” and pledged to block all of President Joe Biden’s Department of Justice nominees in ret
