  • Chris Fall, the head of CAISI, has resigned
  • Fall only took up the job three months ago in April 2026
  • The departure is likely to once again shake up the administration's AI strategy

The head of the Trump administration’s Center for AI Standards and Innovation (CAISI) has resigned from his role, Axios has reported.

Chris Fall served in the role for just three months following his appointment in April 2026, and no reason has so far been given for his departure from the agency.

Arvind Raman, the current head of the Commerce Department office that oversees the AI testing institute is set to temporarily take up the mantle as head of CAISI until a permanent alternative is found.

Another Trump admin departure

Fall’s departure is just one in a string of Trump administration departures so far in 2026. Before resigning, Fall was responsible for working closely with leading US AI labs such as Anthropic, Google's ​DeepMind, OpenAI, ​Microsoft and Elon Musk's xAI to test their frontier and unreleased models for vulnerabilities to prevent them from being maliciously abused.

Trump has placed a big focus on developing AI, with the technology now a key part of both the US economy and its security, with AI models being deployed across federal agencies, police, and the armed forces.

Despite interventions by the US, China has been rapidly closing the gap between its own models and those of US companies. Many Chinese models are cheaper than their US alternatives, making them attractive to US companies feeling the token-cost of US models.

The resignation will likely once again shake up the Trump administration’s AI strategy. The administration has taken a very hands on approach to AI technologies, requiring contractors to provide unrestricted access to their systems and allow the use of their technologies for any lawful purpose. When Anthropic rejected these demands, the company was designated a supply chain risk.

Trump has also called on AI companies to provide stakes in their companies in what Trump has said will “create almost a partnership with the American public”. Trump hasn’t revealed exactly how this partnership would benefit the American public.

On the other hand, Senator Bernie Sanders has proposed an AI sovereign wealth fund that would see 50% of AI company stock placed in a fund that would be used to build infrastructure and fund projects aimed at improving the lives of Americans.
