David Sacks has left his role as the White House's crypto czar and will serve as co-chair of the President's Council of Advisors on Science and Technology.

Formally the change follows the end of his term, but he is expected to retain influence in technology policy and regulatory conversations.

New position and remit

In his new capacity as co-chair of PCAST, Sacks will advise on science and technology matters that affect federal policy and innovation programs.

The council typically provides strategic recommendations to the president on research priorities, technology deployment and long-term scientific strategy.

Unfinished market-structure reform

During his tenure, Sacks advanced a significant reform of U.S. market structure, but the initiative was not finalized before his departure from the crypto-focused role.

Officials note that while the formal position has ended, elements of the reform effort and related consultations are expected to continue under his broader advisory remit.

Implications for crypto policy

The transition shifts Sacks from an operational policy role to a broader advisory platform, where he can impact high-level recommendations without direct managerial authority.

Stakeholders in the crypto and financial sectors will likely monitor PCAST outputs for signals about future regulatory approaches and market-structure developments.
