As Antropic’s relationship with the White House oscillated between warm and cold in 2025, the artificial intelligence giant’s spending on lobbyists skyrocketed.

Anthropic’s monthly lobbying expenditures have increased by roughly 511% over the course of President Donald Trump’s second term in office, rising from $180,000 at the end of the first quarter of 2024 to $1.1 million during the final quarter of 2025. Even as Anthropic publicly butted heads with the Trump administration, the firm has been eager, in private, to pay Republicans and Democrats alike to win over those in power.
