GoPro shares rallied to $1.44 on Tuesday morning after YouTube creator Mark Fischbach disclosed an 8.5% passive stake that made him the action-camera company’s largest individual shareholder. The stock rose 46.06% on Monday to close at 88 cents, for a two-session gain of roughly 140% from the 60-cent low. Trading volume exploded to 134 million shares, more than 14 times the 9.46 million-share average. Short interest stood at 16.19% of the float as of the Aug. 14 settlement date, with a days-to-cover ratio of 3.3. The high-profile stake and short base created a textbook setup for a squeeze. YouTube star Fischbach said the stock looked undervalued and wants the company to succeed; he used GoPro gear in his self-financed horror film Iron Lung, which earned about $51 million on a $3 million budget, and praised the upcoming Mission 1 Pro 8K cinema camera. The rally resolved Nasdaq delisting concerns after thirty sessions below $1, but the company reported Q2 2026 revenue of $105 million down 31.3%, camera shipments down 38%, and a net loss of $51 million.
