Pinterest Inc plunged 7.5%, Facebook-owner Meta Platforms Inc dropped 4.6%, Google-owner Alphabet Inc, which also sells ads online, fell 2.1%.
At current prices Pinterest, Meta, Alphabet and Snap were collectively set to lose about $36 billion in market value.
Twitter also blamed its ongoing battle to close its $44-billion acquisition by Elon Musk for the surprise fall in quarterly revenue. The micro-blogging site’s shares were marginally higher.
Advertisers have pared back spending amid rising interest rates and surging inflation as some of them struggle with labor shortages and supply chain disruptions, Snap Inc said on Thursday.
“If you want proof that companies are nervous about the economic outlook, just look at how media platforms and marketing agencies are bemoaning a tougher advertising market,” Russ Mould, AJ Bell investment director, said.
