Questions
How often do AI assistants get statistics right?
Less than half the time, in this study. Of 1,285 statistics traced from 800 AI answers, 39.9% reached a source that says the same thing and 8.2% reached the source but had changed on the way. 40.1% stopped at a source that couldn’t be checked, and 11.2% led nowhere.
Which AI assistant is most accurate with numbers?
In this study, ChatGPT: 56.5% of its traced statistics matched their source. The other four were between 38.1% and 45.5%. ChatGPT also quoted the fewest numbers (215), and Claude the most (1,089).
Why do so few citations point to a brand’s own site?
AI answers lean on third parties: encyclopedias, forums, video, reviews and news. In Trakkr’s citation leakage study, a brand’s own pages made up a median 4.6% of what AI cited about it, and 28.9% of the pages cited named at least one competitor.
What can a brand do when AI gets its facts wrong?
Fix the sources, not the answer. Put clear, current facts on your own pages (who you are, what you sell, prices, key numbers with their source). Keep profiles such as LinkedIn up to date. Correct public references like Wikipedia through their normal editing process, and say who you are when you do. Then ask the same questions again in a few weeks.
How was the accuracy study done?
On 25 October 2026, Trakkr asked ChatGPT, Perplexity, Google AI Overviews, Gemini and Claude questions that call for a number. It collected 800 answers containing 3,167 statistics, then followed 1,285 of them through the pages cited back to the original source, and judged whether the number still matched.
