Venture capitalist David Sacks confirmed on March 26, 2026 that his 130-day tenure as President Donald Trump's Special Advisor for AI and Crypto has come to a close — not through resignation or dismissal, but because he has legally exhausted his allowance as a special government employee (SGE). He transitions to co-chairing the President's Council of Advisors on Science and Technology (PCAST), a body with advisory authority but no executive power. The White House has confirmed it does not intend to appoint a replacement AI czar. At a moment when AI governance debates are intensifying across Capitol Hill, Brussels, and Beijing, the question of who now steers US AI policy from inside the executive branch has no clear answer.
The mechanics of Sacks' exit are rooted in a rarely discussed corner of federal employment law. Under 18 U.S.C. § 202, a special government employee — a category designed to bring private-sector expertise into government on a short-term basis — may serve no more than 130 days in any 365-day period. The days do not need to be consecutive, which gives administrations some flexibility in scheduling, but once the ceiling is hit, the appointment ends automatically.
Sacks told Bloomberg in an interview on March 26 that he has "used up" his days. He was not fired. He did not quit. He simply ran out of runway under the law.
This is the same legal structure that governs special government employees across administrations — it is designed to prevent prolonged conflicts of interest between private roles and government influence without the full disclosure and divestiture requirements that apply to permanent appointees. Sacks, who remains a general partner at Craft Ventures and a prominent voice in Silicon Valley, was able to serve without divesting his financial interests precisely because of this limited-term category.
Senator Elizabeth Warren had flagged potential conflicts of interest in a letter to Sacks dated September 17, 2025, questioning whether his private crypto holdings and investments created conflicts with his policy duties. The 130-day exit doesn't directly resolve those concerns, but it does end the period of direct government authority.
The clock started when Sacks took the role at the beginning of the Trump administration's second term in January 2026 and ticked down through active days of service. By late March, the counter hit zero.
Despite the compressed timeline, Sacks' 130 days produced a notable policy footprint — particularly on the crypto side of his dual mandate.
On crypto, Sacks was the driving force behind the administration's aggressive push to legitimize digital assets at the federal level. His most concrete legislative win was shepherding the GENIUS Act, a stablecoin-focused bill that moved through the Senate with bipartisan support and represented the most significant federal crypto legislation in years. He also championed the creation of a strategic Bitcoin reserve seeded with government-seized BTC — a policy that was deeply controversial but reflected the administration's broader embrace of crypto as a strategic asset rather than a regulatory problem.
He oversaw the Digital Assets Working Group, which produced a report laying out the administration's framework for crypto market structure, including work toward a separate crypto market structure bill that remains in progress as of his departure, according to CoinDesk.
On AI, the picture is more complex. Sacks was the architect of the administration's posture that AI innovation should be kept largely unregulated at the federal level, with a heavy emphasis on reducing barriers for US companies to compete globally. Under his watch:
As TechCrunch reported, Sacks was closely aligned with the view that the US cannot afford to let regulatory caution cede ground to China's state-directed AI buildout. That philosophy permeated every major AI decision during his tenure. For more context on how the administration's AI posture has taken shape, see our earlier coverage of Trump's AI policy council and executive orders.
Sacks' new role as co-chair of PCAST — alongside Michael Kratsios — sounds significant on paper. The council's membership reads like a who's who of American tech: Nvidia CEO Jensen Huang, Meta founder Mark Zuckerberg, Google co-founder Sergey Brin, Dell founder Michael Dell, AMD CEO Lisa Su, Andreessen Horowitz's Marc Andreessen, and early Coinbase backer Fred Ehrsam, among others, according to Fox Business.
The raw firepower of that group is undeniable. But PCAST's authority is fundamentally different from the czar role.
As a federal advisory committee, PCAST can study issues, hold hearings, solicit expert testimony, and produce recommendations to the president. What it cannot do is set policy, issue directives, or hold operational authority over any government agency. Its reports are advisory — the White House can accept, modify, or ignore them entirely.
Sacks himself acknowledged the distinction to Bloomberg, framing the PCAST role as an opportunity to take on a broader technology mandate rather than the AI-plus-crypto scope he held as czar. But analysts tracking the transition are clear-eyed about what this means in practice.
As Axios reported, the framing from some White House-aligned voices is that Sacks "drops the AI czar label, not the policy influence." That may be true in informal terms — Sacks retains personal relationships with Trump and senior administration officials, and a Zuckerberg-Huang-Andreessen council is unlikely to go unheard. But informal influence is categorically different from holding a formal role with a White House badge and a seat in policy deliberations.
The czar role gave Sacks executive proximity. PCAST gives him a conference table.
The White House's confirmation that it does not plan to appoint a new AI czar creates a genuine leadership gap at the executive level — at least on the organizational chart.
In practice, AI policy will diffuse across several existing structures:
The National Security Council (NSC) retains authority over AI issues that intersect with national security — chip controls, export restrictions, military AI applications, and the competitive posture against China. The NSC has always had a hand in these areas and will likely absorb more of the day-to-day coordination that Sacks handled.
The Office of Science and Technology Policy (OSTP) under its current director continues to handle domestic AI research policy, including the federal AI R&D budget and agency-level implementation of executive orders. OSTP lacks the political visibility of the czar role but has institutional depth.
The Treasury and Commerce Departments will continue to drive regulatory posture on crypto and on AI trade policy respectively — two areas where Sacks held significant influence.
PCAST itself may play a more active role than previous iterations of the council, precisely because of its star-studded membership and Sacks' familiarity with the White House's priorities.
But what's missing is a single integrating voice — someone whose job it is to sit at the intersection of all these workstreams and drive coherent strategy. Sacks played that role. No one has been named to replace it.
The Hill noted that Sacks' departure comes as key legislation remains unresolved — the crypto market structure bill, the national AI preemption framework, and ongoing debates about AI safety standards all require active executive engagement to move forward. With no czar to push them, the legislative fate of these measures becomes less certain.
The list of items Sacks leaves mid-stream is substantial.
The crypto market structure bill — a companion to the GENIUS Act that would define how digital asset trading platforms are regulated — was still being negotiated when Sacks' time ran out. Without a dedicated advocate inside the executive branch, the bill faces a more uncertain path through a Congress that has already shown it can stall on complex financial legislation. Decrypt and Unchained Crypto both flagged this as the most immediate legislative risk from the departure.
The national AI preemption framework — designed to override state-level AI laws with a unified federal standard — is arguably the higher-stakes policy question for the technology industry broadly. Several states have advanced AI liability bills, disclosure mandates, and algorithmic auditing requirements that large AI developers consider operationally burdensome. Sacks was the administration's loudest internal voice for a federal preemption approach. Without him in a formal role, the coalition needed to pass such legislation must reorganize.
AI chip export policy remains in flux. The loosened restrictions Sacks championed represent a significant departure from Biden-era caution. Whether those looser rules get codified or rolled back in future negotiations with allied governments — including ongoing pressure from European partners — depends heavily on who holds the policy pen going forward. For more on the legislative dimensions of AI infrastructure policy, see our coverage of the Senate's AI data center moratorium energy bill.
The AI safety conversation is perhaps the most politically awkward loose end. The administration has been almost entirely focused on AI acceleration — and deliberately so. But as AI systems become more capable and more embedded in critical infrastructure, pressure from both Congress and international bodies to engage more seriously with safety frameworks will grow. Sacks never prioritized safety as part of his mandate. Whoever inherits this portfolio will need to at least manage the optics.
The reaction from Sacks' former peers in venture capital and Big Tech has been notably muted — which itself tells a story.
The headline version of events from The Coin Republic and several crypto-aligned outlets frames this as a clean transition and even an upgrade — Sacks now has a broader mandate and sits alongside the most powerful tech figures in America. The Fox Business coverage leaned into the "expanded role" framing with its headline: "Trump names David Sacks co-chair of tech advisory council, expanding AI, crypto role."
But the more analytically sober read, reflected in Protos and CyberNews, is that the transition represents a real step back from power. The czar role was unique precisely because it was operational. It put a private-sector technologist inside the policy machine with the ability to pick up a phone and reach the president.
A piece from Themeridiem framed the departure as Silicon Valley "losing White House access" — an argument that the tech industry's direct pipeline into the executive branch has narrowed with Sacks' formal exit.
This matters because the US tech industry has grown accustomed to an unusually favorable policy environment under this administration. That environment was in large part a function of Sacks being physically in the building. PCAST dinners and advisory recommendations, however star-studded, are a different category of access.
Sacks' exit does not happen in a vacuum. It happens at a moment when the global AI policy landscape is more consequential than at any point in the technology's history.
China continues to pour state resources into AI infrastructure, compute capacity, and domestic champions like DeepSeek and Baidu. The US strategic advantage in frontier AI has narrowed — not because American companies have slowed down, but because Chinese capabilities have advanced faster than most analysts predicted. DeepSeek's open-weight R1 model in early 2025 was the canary in the coal mine. Chinese AI labs have continued to close the gap.
The European Union has moved aggressively with the AI Act, which has been phased into implementation and now applies directly to high-risk AI applications across all 27 member states. US companies operating in Europe face a compliance regime that the Trump administration has characterized as anti-competitive. Managing the transatlantic AI policy relationship — including pressure on the EU to soften enforcement — was part of Sacks' informal brief. That advocacy now needs a new home.
The UK, Japan, and South Korea have each advanced their own AI governance frameworks in the past six months. The G7 AI governance working group — which the US participates in — requires active executive-level engagement to be effective. Without a czar to play point on international AI diplomacy, that engagement becomes more fragmented.
The timing of Sacks' departure is not catastrophic — US AI policy did not collapse overnight when he ran out of days. But it removes a coherent voice from the international arena at a moment when that coherence matters enormously. Allies want to know who to call in Washington on AI. The answer is now less clear.
The most likely near-term scenarios are as follows.
PCAST becomes more operationally active than advisory bodies typically are. Given Sacks' energy, his continued relationship with Trump, and the caliber of the council's membership, it would be surprising if PCAST issued polite white papers and stopped there. Expect the council to play a more visible role in shaping public narratives around AI policy, even without formal executive authority.
The NSC absorbs the AI security portfolio more explicitly. National security-adjacent AI decisions — on chips, on military AI applications, on the China competition — will likely be consolidated under the NSC structure, where they arguably belong anyway. This is less visible but more durable institutionally.
Legislation stalls without a dedicated champion. The crypto market structure bill and the AI preemption framework both require sustained executive-branch lobbying to move Congress. That lobbying effort loses momentum when it loses a dedicated owner. Expect slower progress on both fronts unless someone is named to fill the coordination role.
A new informal AI voice emerges inside the White House. Administrations rarely tolerate genuine vacuums. The question is whether the next informal AI champion has Sacks' access, credibility in Silicon Valley, and willingness to engage publicly. His combination of venture capital credibility, direct Trump ties, and technology fluency was unusual. Replicating it quickly is not obvious.
For an industry that has spent the past year operating with more White House access than at any point in recent memory, the transition period ahead will be a test. The policy agenda Sacks advanced — minimal regulation, aggressive acceleration, federal preemption of state laws — has enough institutional momentum to carry forward for a while. But momentum without a driver eventually runs out of road.
David Sacks' 130-day tenure as Trump's AI and crypto czar ended not with a bang but with a legal constraint. He ran out of days, not ambition. His move to PCAST keeps him nominally in the advisory ecosystem, but the operational authority he wielded — the ability to pick up a phone, shape a policy memo, and push legislation through sheer proximity to power — goes with the SGE badge.
What the United States AI policy apparatus loses in this transition is coherence: a single accountable voice at the intersection of AI, crypto, national security, and international competitiveness. What it gains is an advisory council stacked with the most powerful technology executives in the world, which may or may not translate into the same thing.
The global AI race doesn't pause for personnel transitions. China doesn't pause. The EU doesn't pause. The question of who steers US AI policy now is not merely an organizational footnote — it is one of the most consequential governance questions of 2026.
