1. The Czar Era Comes to a Close
When David Sacks was appointed as President Donald Trump's AI and Crypto Czar in December 2024 — before Trump even returned to office — the move was read as a clear signal that the incoming administration intended to place technology and digital assets near the centre of its policy agenda. On Thursday, Sacks confirmed that the formal chapter of his White House tenure has concluded. His 130-day term as a Special Government Employee — a classification that imposes a statutory working day limit on outside experts brought into federal service — has been exhausted. Sacks announced via a post on X that he is transitioning into the role of co-chair of the President's Council of Advisors on Science and Technology, known as PCAST, alongside Michael Kratsios, the director of the White House Office of Science and Technology Policy.
2. The PCAST Role and Its Scope
PCAST is a standing federal advisory body composed of industry leaders, academics, and technology executives. It was established under this administration by presidential executive order in January 2025, with a mandate to provide evidence-based policy recommendations to the president and the White House on science, technology, and innovation. Sacks described PCAST as the principal external advisory body tasked with shaping U.S. technology policy, and framed his appointment as co-chair as an expansion of his advisory scope rather than a reduction in influence. "I think moving forward as co-chair of PCAST, I can now make recommendations on not just AI but an expanded range of technology topics," he told Bloomberg in an interview. Those topics, he indicated, include quantum computing, advanced semiconductors, nuclear energy, and AI infrastructure — domains that extend well beyond the crypto and AI brief he held as czar.
3. The Council's Inaugural Membership
Trump approved PCAST's inaugural 13-member slate alongside Sacks' appointment as co-chair. The membership list reads as a who's who of U.S. technology leadership: Jensen Huang of Nvidia, Mark Zuckerberg of Meta, Lisa Su of AMD, Larry Ellison of Oracle, Marc Andreessen of Andreessen Horowitz, and Michael Dell of Dell Technologies. The sole representative with direct ties to the cryptocurrency industry is Fred Ehrsam — co-founder of both Coinbase and the prominent crypto venture firm Paradigm. That membership profile positions PCAST as a council oriented primarily around artificial intelligence, semiconductors, and enterprise technology, with crypto represented but not at the centre of its mandate.
4. What Sacks Achieved in the Czar Role
During his 130-day tenure, Sacks served as the administration's primary internal advocate and coordinator on digital asset policy. His most significant legislative achievement was his involvement in the passage of the GENIUS Act — the first comprehensive federal framework for stablecoin regulation in U.S. history — which represented a foundational win for an industry that had spent years lobbying for statutory clarity. More recently, Sacks and his White House team have been engaged in internal coordination around the Digital Asset Market Clarity Act, the market structure bill currently working through Senate negotiations. Patrick Witt, the White House's crypto policy adviser, has been carrying much of the day-to-day engagement on the Clarity Act in the weeks leading up to and following the stablecoin yield compromise that has divided the industry.
5. The 130-Day Limit and Prior Congressional Questions
The Special Government Employee classification that governed Sacks' czar appointment carries a statutory limit of 130 working days in any calendar year, a rule designed to manage conflicts of interest and ensure that outside experts do not become de facto permanent government officials without the vetting and accountability that accompanies Senate-confirmed positions. The limit had been flagged by Democratic members of Congress last autumn, who argued at the time that Sacks may already have been approaching or exceeding that threshold. His transition to PCAST avoids that constraint entirely: the advisory council position carries no equivalent time restriction, enabling Sacks to remain continuously engaged with White House technology policy in a formal capacity going forward.
6. Ethics Disclosures and Financial Conflict Management
Sacks' tenure as czar was also notable for the scale of the financial divestments he undertook to comply with federal ethics requirements. Reports indicate that he divested more than $200 million in digital asset-related holdings before assuming the role — a disclosure that underscored both the significant personal financial interests he had accumulated in the crypto space and the legal obligation to separate those interests from his policy-making responsibilities. In a government role where he was influencing stablecoin legislation, Bitcoin reserve policy, and market structure rules for the digital asset sector, those divestments were both legally required and politically significant. His move to PCAST may involve different or lighter ethics obligations than the Special Government Employee classification, though the specific requirements of the co-chair role have not been publicly detailed.
7. Continuity on AI Policy
While much of the public attention on Sacks' departure has focused on its implications for crypto, his own framing of the transition has emphasised AI above all. In his public statements and posts surrounding the PCAST announcement, Sacks focused specifically on advancing the administration's recently published AI framework, reducing the patchwork of state-level AI regulations by pushing for a unified federal approach, and guiding U.S. technology policy across the domains that will define the country's competitive position over the next decade. His description of the PCAST mandate as being about ensuring America "leads and wins" in artificial intelligence reflects the administration's framing of AI as a national security and economic competitiveness priority as much as a regulatory policy question.
8. What the Transition Means for Crypto Policy
Sacks' departure from the czar role prompts genuine questions about the trajectory of White House engagement on digital asset policy at a moment when several critical pieces of the agenda remain unresolved. The Clarity Act has not yet passed; its stablecoin yield provisions remain contested; the U.S. strategic Bitcoin reserve ordered by Trump through executive order has not been legislatively established; and the crypto tax reform agenda has not been addressed. Patrick Witt retains his position as the White House's crypto adviser, and the administration's overall posture toward digital assets has not shifted. But the loss of the highest-profile internal champion for the sector — and the most direct line from the crypto industry into the Oval Office — at this specific legislative moment raises legitimate questions about momentum.
9. Mixed Reactions From the Industry
Industry responses to the transition have been divided. Some market participants and commentators viewed Sacks' departure as a sign that the White House's attention to crypto policy is diminishing, with ongoing criticism that the czar role produced fewer legislative outcomes than the industry had hoped for in its 130 days. Others characterised the move as a lateral one rather than a retreat — noting that Sacks' continued presence on PCAST alongside some of the most influential figures in U.S. technology ensures he retains a meaningful voice in the policy environment that shapes crypto's long-term operating conditions. The Bitcoin price, which declined during the period when the news broke alongside broader macro-driven selling, offers ambiguous signal on the market's interpretation of the policy implications.
10. A Broader Technology Agenda Takes Shape
The PCAST framework that Sacks now co-chairs reflects an administration that is thinking about technology competitiveness in terms larger than any single sector. Quantum computing, next-generation semiconductors, nuclear energy, and AI infrastructure are each areas where the U.S. faces meaningful competition from China and other nations, and where federal policy decisions will shape decades of outcomes. For the crypto industry, the practical question is whether Sacks' broader mandate at PCAST makes him more or less useful as an ally — whether the elevation to a wider technology advisory brief enhances his credibility and influence with the president on crypto-specific questions, or whether it dilutes the focused attention the sector benefited from during his czar tenure. The answer will become clearer as the Clarity Act's final stages unfold over the coming months.
