GoPro Shares Have Their Best Day Ever: A Popular Blogger Becomes the Company's Largest Shareholder

Shares of GoPro, a small-cap action-camera manufacturer that just two months ago warned of a risk of default due to rising memory card prices, soared 46% on August 31, marking the best single-day gain in the company’s history. The rally began after it was revealed that video blogger Mark Fischbach, known online as Markiplier, had become GoPro’s largest shareholder. His YouTube channel has nearly 39 million subscribers.

GoPro shares rose 46% on August 31 to $0.88. This is the sharpest jump in the company’s history, according to Stocktwits. Early in the morning trading session on September 1, the stock surged nearly 90%.

Investors reacted to a Bloomberg report: the agency noted that Mark Fischbach, known on YouTube as Markiplier, had acquired an 8.5% stake in GoPro, becoming the company’s largest shareholder. As of August 20, Fischbach owned 13.5 million shares of the company. At the close of trading on August 31, this stake was worth $11.8 million, and the manufacturer’s total market capitalization reached nearly $161.7 million.

Fishbach is neither a professional investor nor an activist like Bill Eckman or Carl Icahn; he is an avid GoPro user who can’t believe the company is valued so low, according to Bloomberg. “I saw how much the stock was trading for and thought: it seems undervalued. (...) I want the company to succeed,” Fischbach said in an interview with the agency.

The blogger told Bloomberg that his investment in GoPro is part of a broader mission to make filmmaking more accessible. Earlier this year, Fishbach released the film *The Iron Lung*, which grossed $51 million at the box office—on a budget of $3 million.

Among Fishbach's other investments is the purchase of a stake in Strada, a developer of video editing tools, the agency reports. It also notes that the blogger has a sponsorship deal with GoPro.

Since the beginning of 2026, GoPro's stock price has fallen by more than 36%—even taking into account the rally on August 31.

In May, the company announced that it had begun exploring strategic alternatives, which could include a sale to another company or a merger with another player. In June, it reported significant doubts about its ability to continue operations. GoPro cited a sharp rise in memory card prices and a reduction in their production, which led to a downward revision of its sales forecast for the current year and affected the procurement of other components.

At the end of the second quarter, GoPro’s revenue fell 31% year-over-year to $105 million, while its net loss rose nearly 219% to $51 million.

Only one Wall Street analyst is covering the company. He recommends selling its stock. His price target is $0.50, which is 43% below the stock's most recent closing price.
