Reps. Lori Trahan (D-MA-03) and Jay Obernolte (R-CA-23) introduce a bill to build a competitive marketplace of independent verifiers for frontier AI models.

WASHINGTON, July 23, 2026 /PRNewswire/ — Fathom welcomes the introduction of the FRONTIER Act, the most complete federal framework yet for independent, third-party verification of frontier AI. The legislation is built to earn public trust as AI technology continues to accelerate. As frontier systems begin to take autonomous action in the world, the gap between what these models can do and our ability to keep them in check is widening. FRONTIER is the starting point to close that gap.

“AI governance keeps running into the same wall. The technology is hard to measure and it moves faster than any law can keep up with,” said Andrew Freedman, Co-Founder and CEO of Fathom. “Trying to write the perfect rules and freezing them in place won’t work. What will work is a competitive market of independent verifiers who are accountable for real-world outcomes and who the government can actually count on. The FRONTIER Act shows we can move fast and still get this right.”

The bill gets the fundamentals correct. It sets one public standard – the adequate mitigation of catastrophic risk – and holds both the AI companies and their independent verifiers accountable to it. FRONTIER does not freeze a single testing method into statute. Instead, it licenses competing verification organizations, allows them to sharpen their methods, and gives the government the power to revoke a license when a verifier’s work does not hold up in the field. That is how you build a system that keeps pace with the science instead of falling behind it.

Fathom thanks Reps. Trahan and Obernolte for their leadership, and for their courage in releasing a discussion draft, inviting scrutiny, and incorporating substantive improvements from across the field. One priority improvement as the bill advances: giving the government a fuller range of tools to act upstream – for pushing companies to close identified gaps in risk mitigation early, rather than only once a catastrophe is imminent. We are committed to working with these sponsors, committees of jurisdiction, and Congressional leadership to continue refining the bill in the weeks and months ahead.
