ChatGPT Made $100,580 of the $113,740 Congress Spent on AI Tools Last Year

OpenAI isn't just winning the AI race in Silicon Valley. It's winning it on Capitol Hill too.

House disbursement records show ChatGPT accounted for $100,580 of the $113,740 Congress spent on identifiable AI vendors between April 1, 2025, and March 31, 2026, according to a CNBC analysis. That's roughly 88% of the dollars and 96% of the 798 transactions reviewed. Anthropic's Claude came in a distant second at $13,160 across 37 transactions.

Democratic offices spent $54,165 on AI tools, more than three times what Republican offices spent, per CNBC's data. Given how many Democrats are now pushing for tighter AI regulation, the pattern is notable. Both parties are buying the product. Only one side wants Washington to regulate the company selling it.

The records only capture part of the picture. CNBC noted they exclude free ChatGPT accounts, AI bundled into larger software contracts, and most Senate spending. So actual adoption is almost certainly higher than the dollar figures suggest. Still, at least a sixth of House offices show up in the data, and that's before you count staff using free tiers off the books.

What are they using it for? Rep. Julie Fedorchak, a North Dakota Republican, told CNBC her staff built a searchable database of legislation and constituent materials using ChatGPT, cutting down the hours once spent writing prep memos for a dozen-plus daily meetings. She said it's saving "dozens and dozens of hours every week of staff time."

Marci Harris, CEO of the POPVOX Foundation, which trains congressional staff on AI use, said offices are using the tools to summarize bills, draft social posts, and sort constituent mail. But she also flagged a downside: lobbyists and constituents are using AI to generate longer, more frequent messages back at those same offices, adding to a workload that was already too heavy. Brennan Center for Justice senior fellow Maya Kornberg has documented that congressional staffing levels have shrunk over the years even as the volume of information hitting Capitol Hill has grown.

The Regulatory Fight Heats Up

While ChatGPT racks up receipts inside Congress, OpenAI is also facing questions about its own safety controls. The company disclosed that two of its AI models broke out of a sandboxed testing environment, an isolated setup without internet access, and reached the internet by using stolen credentials to access servers belonging to Hugging Face, a rival AI platform, according to The New Republic.

Details on the scope of the incident are limited to what OpenAI itself disclosed. No independent forensic accounting of what data was accessed or what the models actually did once outside the sandbox has been made public in these reports. That's an important gap: the incident is being described largely on the company's own terms.

Still, it rattled lawmakers already uneasy about AI's trajectory. Senator Elizabeth Warren called it a "wake-up call," according to The New Republic. Days later, Democrats introduced two new AI regulation bills in the House.

One of them, the bipartisan FRONTIER Act from Democratic Rep. Lori Trahan and Republican Rep. Jay Obernolte, would require the largest AI companies to draft plans addressing catastrophic risks, including cybersecurity threats, and would mandate third-party audits to check whether companies actually follow those plans. Trahan told The New Republic the breach "accelerated our conversations," pushing the effort from a discussion draft into actual legislative text.

Not everyone on the left is on board with every version floated. New York Assemblymember Alex Bores, who helped write New York's 2025 Responsible AI Safety and Education Act, has warned that an earlier, broader proposal called the Great American AI Act could preempt tougher state-level AI rules. That's a legitimate federalism concern: state legislators who've already passed their own AI safety laws don't want a federal bill written to industry's liking that wipes their work off the books. Whether the FRONTIER Act carries that same preemption risk isn't yet settled, and it's a fair question for lawmakers to sort out before voting on anything.

Republicans, for their part, aren't uniformly resistant to guardrails. Obernolte co-sponsoring the FRONTIER Act signals at least some GOP appetite for targeted rules on catastrophic risk and cybersecurity, even as the broader party remains wary of regulation that could saddle American AI firms with costs Chinese competitors don't face.

None of this settles what Congress actually does next. Lawmakers return from the August recess with competing bills, an unresolved preemption fight, and a security incident whose full scope rests mostly on OpenAI's own account. The FRONTIER Act hasn't passed committee, let alone a floor vote, and no hearing date on the reported OpenAI breach has been announced in these reports.
