Former UK Prime Minister Rishi Sunak has officially taken up two high-profile advisory roles at leading US technology firms Microsoft and Anthropic, marking his entry into the global tech and artificial intelligence sectors after his political career.

According to documents released by the Advisory Committee on Business Appointments (ACOBA), Sunak will serve as a part-time senior adviser for both companies, offering strategic guidance on macroeconomic and geopolitical trends. His positions come with restrictions, including a ban on lobbying the UK government on behalf of either organization.

The report highlights that Sunak’s role at Microsoft will focus on providing insights into economic shifts, innovation strategies, and global policy developments relevant to emerging technologies. He assured the committee that he would not receive any personal financial benefit from the position, as all earnings will be donated to The Richmond Project, his charitable foundation dedicated to improving numeracy and financial literacy among children and adults.

In a separate filing, ACOBA confirmed that Sunak had also joined Anthropic, an influential artificial intelligence startup, in a similar advisory capacity. The former prime minister will collaborate with Anthropic’s senior leadership to offer his expertise on policy, regulation, and ethical implications of AI technologies.

Anthropic, in a statement to AFP, expressed enthusiasm for Sunak’s appointment, saying, “His experience will provide valuable strategic perspective as we work to ensure AI benefits humanity.” The company added that all parliamentary rules regarding conflicts of interest would be followed.

Sunak’s new ventures follow widespread speculation about his move into Silicon Valley’s tech scene after leaving office in July 2024. During his premiership, he positioned the UK as a key player in global AI regulation, hosting the landmark AI Safety Summit at Bletchley Park in 2023.

Before entering politics, Sunak had an extensive career in finance, working at Goldman Sachs and later at major hedge funds. Interestingly, he also returned to Goldman Sachs as a senior adviser in July 2025, expanding his post-political portfolio across technology and finance.

The move mirrors that of Nick Clegg, another former UK deputy prime minister, who joined Meta as President of Global Affairs in 2018 — signaling a growing trend of political figures transitioning into influential corporate advisory roles within the tech industry.
