What happened
Newly reviewed congressional disbursement records, first reported by CNBC, show that House offices and committees spent more than $113,740 on AI tools in the fiscal year ending March 31, and ChatGPT captured the overwhelming majority of it: roughly $100,580 across 798 separate transactions, compared to just $13,160 across 37 transactions for Anthropic's Claude. Democratic offices spent more than triple what Republican offices did, $54,165 versus $15,782. Staffers reported using the tools for drafting memos, summarizing legislation, preparing hearing materials, responding to constituents, and producing social media content. The gap is notable given how competitive the enterprise AI market has been in 2026, with Anthropic and other vendors aggressively pursuing government and enterprise contracts; in one of the largest US institutional buyers of AI tools, OpenAI's ChatGPT is winning by a wide margin.
Why it matters for your business
Government adoption data is one of the more concrete, hard-to-fake signals of which AI tools are actually sticking in real institutional use, as opposed to marketing claims or funding announcements. If your business is choosing between AI vendors for drafting, research, or customer-facing tools, this kind of usage-and-spending data, not just feature comparisons, is worth tracking, because heavy institutional adoption tends to mean better support, more integrations, and longer product roadmaps. It's also a reminder to audit your own AI tool spending the way Congress's records were just reviewed: do you actually know which tools your team is using, and for how much?
