Pinterest’s AI-driven discovery model fuels international gains, but US growth slows

The news: Pinterest was more or less in line with expectations in Q3, with both revenues and user growth slightly exceeding forecasts. The company reported $1.1 billion in Q3 2025 revenues, up 17% YoY, but shares dropped about 20% in extended trading after the company issued slightly soft Q4 guidance; the $1.33 billion midpoint of its revenue forecast was below Wall Street’s projections ($1.34 billion).

US versus the world: Depending on if you’re looking at the US or the rest of the planet, Pinterest’s success looks pretty different.

• Monthly active users rose to 600 million globally, a 12% annual increase, with international markets up 16% and accounting for much of the new momentum.
• Average revenue per user (ARPU) climbed 5% globally, buoyed by 31% growth in Europe and 44% in the Rest of World. US ARPU was just $7.64 (5% YoY growth).
• Non-US revenue growth was especially strong—up 41% in Europe and 66% in emerging markets—as new advertiser adoption accelerates and the platform proves its ability to scale beyond North America.
