Correction — November 11, 2026

Today we discovered an error in our AI Campaign Finance Tracker. A bug in how our tracker deduplicates filings has meant that we have undercounted spending from American Mission, part of the Leading the Future network, by about $9.6m, and double-counted about $1.4m of spending by Guardrails Alliance, a pro-safety PAC.

The bug was introduced in late June, and most of the error built up in late October. Since the bug was introduced, our headline figures have therefore been undercounting “pro-innovation” spending and overcounting “pro-safety” spending. Post-midterms, our headline figures were $44.4m pro-safety vs $27.9m pro-innovation, or 1.6 to 1. The corrected figures are about $42.9m vs $37.4m, about 1.15 to 1. Pro-safety groups still outspent industry, but by much less than we reported.

We know lots of people relied on our tracker as a source of truth in the midterms: as the editor ultimately responsible for it, I am very sorry that its numbers have not been accurate.

The tracker has now been corrected and checked against FEC filings, so it is now accurate. Going forward, if we run a similar project in 2028 we will implement better review processes to make sure an error like this cannot happen again.
