This social-media stock plunges 20% today as unexpected tax charges and rising AI spending shake investor confidence — Facebook, Instagram, and WhatsApp growth sparks market concern
Pinterest stock plunged 20% on Thursday after the company’s third-quarter 2025 earnings and holiday-quarter guidance fell short of Wall Street expectations, sending shockwaves across the social media sector. The drop erased all of Pinterest’s gains for the year, pushing shares below $31 and valuing the company near $21 billion.
Pinterest reported adjusted earnings per share (EPS) that missed analyst forecasts, while revenue growth slowed significantly in its core North American market, which accounts for more than 70% of total sales.
