Markiplier Buys 8.5% of GoPro, Stock Surges 46%

YouTuber Mark Fischbach (Markiplier) filed an SEC Schedule 13G disclosing 13.5 million GoPro Class A shares — an 8.5% stake worth around $9 million, built quietly as of July 13. Bloomberg broke the story August 30; GPRO closed up 46.1% the following day on volume more than 20 times its recent average. Fischbach is now the largest single holder of Class A stock, though founder Nicholas Woodman retains roughly 63% of total voting power through Class B shares.
