Who he is
David Oliver Sacks (born 1972) is a South African-born American technology entrepreneur, venture investor and political adviser. He worked as a PayPal executive, founded enterprise-messaging company Yammer (acquired by Microsoft in 2012), and co-founded venture investment firm Craft Ventures in 2017. He co-hosts the technology-and-politics program All-In. His venture work includes early investments in companies such as Palantir and SpaceX; an investment link should not be confused with company management or government authority. Craft Ventures biography.
Trump announced Sacks as his proposed White House AI and cryptocurrency adviser in December 2024. He served during 2025 as a special government employee, then said in March 2026 that he had reached the time limit on that arrangement. He continued as co-chair of the President’s Council of Advisors on Science and Technology (PCAST) with Michael Kratsios. Reuters — March 27, 2026 · Official PCAST roster.
History: Stanford, Peter Thiel, PayPal and Elon Musk
At Stanford in the early 1990s, Sacks worked with Peter Thiel on the conservative Stanford Review; they co-authored the 1995 book The Diversity Myth, criticizing multiculturalism and campus politics. Sacks subsequently worked with Thiel and Elon Musk in the PayPal-era technology network. This is a longstanding documented intellectual and professional relationship, not merely an overlap in recent Trump appointments. Guardian — historical profile, September 20, 2026.
Craft Ventures and Sacks also have investment relationships with technology firms in the wider ecosystem, including companies in AI, aerospace, and defense. Holdings can be indirect, can change through sales or fund investments, and must be dated before describing a present interest. Craft Ventures.
Trump fundraising and the political transition
On June 6, 2024, Sacks and other technology investors hosted a Trump fundraising event at Sacks’s San Francisco home. Tickets were advertised at high-dollar levels, and contemporaneous accounts reported that the event raised about $12 million. That is a reported event total, not a claim that Sacks personally contributed $12 million. Sacks also used his All-In platform to advocate policy preferences and discuss the administration.

Inside government: signed policy and advisory leadership
2025 White House AI Action Plan. Sacks was a named principal author, together with Michael Kratsios and Marco Rubio, of the administration’s July 2025 America’s AI Action Plan. The published plan addressed faster data-center and semiconductor permitting, private-sector input on AI regulation, federal AI procurement and international technology competition. This is a named, original-document policy role. White House — July 2025 AI Action Plan.
March 2026 PCAST co-chairmanship. The White House appointed Sacks and Kratsios as co-chairs, with members including Jensen Huang, Marc Andreessen, Larry Ellison, Mark Zuckerberg, Sergey Brin, Lisa Su and others. PCAST is an advisory body. White House — March 25 appointments · Full PCAST entry.
Specific regulatory action. In January 2026, Commerce/BIS changed the review standard for certain H200 exports to China from a presumption of denial to case-by-case review with conditions. BIS issued the signed public rule. Sacks's position in technology policy is relevant to tracing how priorities were shaped, but an issued BIS rule is not itself a personal signature by Sacks. Federal Register — January 15, 2026 rule.
Financial interests, divestment and ethics waivers
March 5, 2025 — cryptocurrency waiver. White House counsel David Warrington issued a limited waiver under 18 U.S.C. § 208(b)(1) allowing Sacks to participate in specified digital-asset policy matters despite identified interests, subject to the memorandum's conditions. The memo describes divestitures, including liquid cryptocurrency positions. Original White House cryptocurrency waiver.
2025 — AI interests waiver. A separate White House memorandum granted a limited waiver concerning AI-related investments and policy matters. It described additional divestitures and remaining indirect interests and determined that participation within the waiver's limits was appropriate. Those financial interests and the authorization are essential to evaluating decisions; neither should be erased from the record. Original White House AI interests waiver.
Investigative dispute. A November 2025 New York Times investigation examined the breadth of investments held by Sacks or Craft and the policies affecting AI and crypto businesses. Sacks rejected the conflict-of-interest allegations and the White House cited divestments and ethics arrangements. Identifying any actual financial benefit requires current holding records, specific policy actions and beneficiary dates.

Nvidia, Jensen Huang and semiconductor decisions
Sacks co-chairs PCAST, which included Nvidia founder Jensen Huang beginning in March 2026. The White House AI Action Plan and Commerce's separate H200 licensing rule addressed an industry with enormous financial and national-security stakes. Appointment record · BIS rule.
On November 12, 2026, The Wall Street Journal described Sacks as among Huang's White House allies during the administration's internal disputes about advanced-chip sales to China. That reported relationship is important alongside Huang's direct presidential access and resignation amid the Nvidia board investigation. The next evidence to seek is dated Sacks/Huang/Commerce communications, advisory recommendations, recusals, and the actual export-license decision record.

Cross-check: where Sacks appears in the wider network
Across the network, the research question is how private capital and political organizing intersect with signed government decisions and identified beneficiaries. Federal agency actions are traced to their actual decision-makers, rather than assigned to everyone in the same professional circle.
