Pinterest shares tumbled 18% on Wednesday after the company issued a weaker-than-expected revenue forecast, raising concerns that the image-sharing platform is losing ground to larger digital advertising rivals amid growing tariff-related pressures. If losses hold, the drop would wipe about $4.36 billion off Pinterest’s market value.
The sharp decline contrasts with strong third-quarter results from advertising heavyweights Alphabet, Meta, and Reddit, all of which reported robust ad spending fueled by AI-powered targeting and larger global reach. Analysts said Pinterest’s smaller scale and slower innovation pace are limiting its ability to compete effectively.
Chief Financial Officer Julia Donnelly cited weaker ad spending in the United States and Canada — Pinterest’s biggest markets — as retailers face thinner margins due to new tariffs. “Larger U.S. retailers are navigating tariff-related margin pressure,” Donnelly said, adding that China-based e-commerce giants such as Temu and Shein have also reduced marketing budgets after the removal of the “de minimis” import exemption.
Pinterest now expects revenue between $1.31 billion and $1.34 billion for the current quarter, with the midpoint slightly below analyst expectations of $1.34 billion, according to LSEG data.
“Performance has been fine, but we struggle to see a catalyst for growth,” said analysts at Piper Sandler. Morgan Stanley added that Pinterest “failed to deliver” in a market increasingly rewarding innovation and upward earnings revisions.
Despite Wednesday’s steep loss, Pinterest shares remain up 13.6% for the year — outpacing Meta’s 7.2% gain over the same period.
