115th119th

## What the chart shows

Industry representatives made up 37.3% of witnesses at US congressional AI hearings in the 119th Congress (2025), up from 13.0% in the 115th (2017–2018). Industry is now the largest of the three sectors shown.

Government’s share fell from 34.8% to 9.8% and academia’s from 26.1% to 14.7%. The remaining witnesses, from civil society, non-profits and other groups, rose from 26.1% to 38.2%; they are not in the data file, and we work them out as the remainder.

## Key numbers

| Measure                         | Value |
| ------------------------------- | ----- |
| Industry, 119th Congress        | 37.3% |
| Industry, 115th Congress        | 13.0% |
| Government, 119th Congress      | 9.8%  |
| Government, 115th Congress      | 34.8% |
| Academia, 119th Congress        | 14.7% |
| Other (derived), 119th Congress | 38.2% |

## How to read it

- Each Congress spans two years: the 115th is 2017–2018 and the 119th began in January 2025, so its figures cover 2025 only.
- The AI Index text calls industry the largest witness group; the “other” group (civil society, non-profits and others), at 38.2%, is slightly larger. It is not in the data file; we derive it as 100% minus the three sectors shown.
- Shares of all witness appearances in each Congress.
