Former British prime minister Rishi Sunak has joined both Microsoft and Anthropic as a senior advisor.

Speaking about the move in a LinkedIn post, he said: “Microsoft has driven productivity improvements for decades and Anthropic is one of the most exciting AI frontier labs.”

Sunak added that he hopes that technology will “transform our world "and play a key role in determining the future of humanity.

He went on to say that the technological revolution will be as “profound” as the industrial revolution.

The ex-prime minister said that both Anthropic and Microsoft are tackling major strategic issues on how to make technology work “for the benefit of our economies, our security and our society.”

“In my role as a senior adviser, I want to help these companies ensure that this shift delivers the improvements in all of our lives that it can,” he continued.

He also emphasised that all proceeds from these roles will be donated in full to the Richmond Project charity.

The charity, which was founded by Sunak and his wife Akshata Murty, focuses on improving mathematical skills across all age groups.

The organisation’s mission is to build confidence in numbers and break down barriers to mathematics in families and communities.

Sunak resigned as leader of the Conservative Party after losing the general election in July 2024 but remains a member of Parliament.

According to a Reuters report, Anthropic has confirmed that Sunak will advise Anthropic on strategy, macroeconomic and geopolitical trends.

The role will focus on global strategic issues, not specific UK policies, and Sunak is prohibited from initiating contact with British government officials on behalf of Anthropic.

At Microsoft, Sunak will provide strategic insights on macroeconomic and geopolitical trends.

He will speak at Microsoft's annual summit, according to a letter of advice from Advisory Committee on Business Appointments (ACOBA) interim chair Isabel Doverty, published on the association's website on Thursday.

According to the letter, the former prime minister will not be able to lobby for the company for two years from the last day he held ministerial office, and he won’t be able to use privileged information acquired during his government tenure.

In July, Sunak returned to work for Goldman Sachs as a senior adviser, rejoining the company where he began his career in finance in the early 2000s.
