Congress's Preferred AI: ChatGPT Leads in Capitol Hill Spending

An analysis of House spending records indicates that OpenAI's ChatGPT has emerged as the artificial intelligence platform of choice among members of Congress. The chatbot accounts for a significant majority of AI-related expenditures by congressional offices, committees, and institutional accounts. This data highlights the increasing integration of AI into the operational workflows of the legislative branch, with applications ranging from administrative support to policy analysis and public engagement.

Congressional Offices Embrace ChatGPT for Enhanced Productivity

In a detailed examination of House disbursement records, covering the period up to March 31, 2026, it was found that OpenAI’s ChatGPT commanded approximately 90% of all funds allocated to artificial intelligence tools. This translates to an impressive $100,580 across 798 distinct transactions, out of a total AI expenditure of at least $113,740. While other AI solutions are in use, Anthropic’s Claude was a distant second, with spending totaling $13,160 over 37 transactions.

The financial breakdown also revealed a notable disparity in AI adoption along party lines. Democratic offices collectively spent $54,165 on AI purchases, a figure three times higher than the $15,782 spent by their Republican counterparts. It is important to note that these figures exclusively represent paid subscriptions and do not encompass free AI accounts or AI functionalities integrated into broader software agreements.

Congressional staffers are deploying ChatGPT and similar AI tools for a wide array of critical tasks. These applications include the meticulous drafting of internal memos, the efficient summarization and analytical review of complex legislative texts, and the preparation of materials for hearings. Furthermore, AI assists in streamlining communications with constituents and organizing extensive policy research, thereby enhancing overall operational efficiency within legislative offices.

The widespread adoption of ChatGPT in Congress signals a new era for legislative operations, where AI is increasingly viewed as an indispensable asset. The technology's ability to automate routine tasks and assist in complex analytical processes could lead to more efficient governance and better-informed policy decisions. However, it also raises questions about data privacy, AI ethics, and potential biases in algorithmic outputs that will need to be addressed as reliance on these tools deepens.
