OpenAI has held early talks to partner with The Trade Desk, a publicly traded ad tech company, to help the ChatGPT maker sell ads, according to three people with knowledge of the matter. The talks indicate that OpenAI, which launched ads in ChatGPT in early February, will initially lean on external partners to help it sell ads and quickly ramp up its business. For instance, The Trade Desk offers an automated platform for advertisers to place ads on a large scale. It also offers technology to target ads and measure their performance.
