Congress’s favorite AI tool? ChatGPT

Democratic offices accounted for the majority of these expenditures, using the technology for legislative research, drafting, and constituent communication.
Why it matters
This highlights the rapid integration of generative AI into government operations and the dominance of OpenAI in the public sector software market.
OpenAI’s ChatGPT is Congress’s AI tool of choice so far in terms of money spent, according to a report from CNBC .
OpenAI received roughly 90% of all spending on AI tools by House offices, committees and institutional accounts during the year ending in March 31, per House disbursement records. CNBC found that Congress spent around $100,580 across 798 transactions on ChatGPT, out of at least $113,740 in total AI spending. Anthropic’s Claude trailed in second place at $13,160 across 37 transactions.
Democratic offices accounted for $54,165 in AI purchases, three times the $15,782 spent by Republican offices.
The insights exclude any Congressional AI adoption from free accounts or AI bundled into broader software contracts.
Congressional staffers are using ChatGPT and other tools to write memos, summarize and analyze legislation, respond to constituents, prepare hearing materials, sort through policy research, and even draft social media posts.
