ChatGPT ads add advertisers fast while spend stays flat

A Search Engine Land analysis of AdClarity estimates found monthly active ChatGPT advertisers in the US grew from 839 in April to 17,934 in August, while monthly spend stayed between $87 million and $94 million from May to August. Average spend per advertiser fell by roughly 85%, and the top 100 advertisers took 43% of spend. Software for work led spending, while retail and consumer brands took 7.6%.
Our take
More buyers are chasing the same impressions, and one in three early advertisers had stopped by August. Test only if you sell something people use ChatGPT for at work, and set up your pixel, the Conversions API and UTMs before the first dollar goes out. Judge the channel on tracked sales, not on how many brands now run ads there.
