How much should I trust AI market research, and how do I verify it before betting on it?

Trust it as a fast first draft, never as evidence: models hallucinate 5 to 10 percent of the time on hard questions, quote stale pricing, invent statistics, and use more confident language precisely when they are wrong. Verify with three habits: open every citation and confirm it says what the AI claims, ask the same question to two or three different models and investigate any disagreement, and trace every number back to its original source before it goes in a deck. Even Deloitte and KPMG have shipped hallucinated reports, so a founder deck built on unverified AI research is a real credibility risk.
