Do ads in ChatGPT change the answer?

OpenAI says no. Ads sit below the answer and are produced separately, so the two can show different prices for the same product.

OpenAI says ads don't influence the answers ChatGPT gives. Ads appear below the answer, labeled as sponsored, and are matched to the topic of the conversation, past chats and past ad interactions (OpenAI).

Because the ad and the answer are produced separately, they can disagree. In Core dna's November 2026 US test, Best Buy's ad showed the Sony WH-1000XM6 at $458, its comparison value, under an answer that had Best Buy's real price, $378. For the JBL Flip 7 it went the other way: the answer quoted a Best Buy price Best Buy wasn't offering, and Best Buy's ad underneath showed the right one. See the full findings.
