AOL has adtech advertisers setup with some large customer base probably 3rd or 4th to Google/Facebook. It also owns publishers like HuffPost, TechCrunch etc.
That said, single market players like TheTradeDesk or Xandr are larger in their own markets than verizon media, but probably not compared to the combined publisher and advertiser business: https://www.atlantic.net/vps-hosting/top-10-dsp-providers/
But then IAC, Verizon Media’s biggest properties, would be a mix of different things.

…color me skeptical that there’s a bright future there.
Most people’s lunch is being eaten by the big two. Snap had to go with a different ads biz model to not directly compete with the big two.
It doesn’t stop Verizon Media, now Yahoo, from being the 5th or 6th biggest ad[tech] and online ads business. I’m hedging 6th in case there’s some one else between Microsoft and Amazon.
