Classover Holdings (KIDZ) stock surged over 36% in premarket on Tuesday after a Securities and Exchange Commission (SEC) filing revealed that major asset manager BlackRock Inc. (BLK) has established a notable position in the education technology firm.
According to the filing, BlackRock holds 87,463 shares, representing an 8% stake in the Class B stock of Classover.
The asset manager reported sole voting and dispositive power over the entire position. The filing indicates that the stake is part of BlackRock’s broader investment portfolio activity rather than an activist position.
Classover operates in the education technology sector, with a growing emphasis on artificial intelligence-driven learning tools and digital classroom innovation.
The company has recently expanded its focus toward AI-enabled instruction systems and interactive learning technologies as it competes in the fast-evolving EdTech market.
On April 22, the company inked a partnership with ICreate Education Technology to develop AI and robotics learning environments in North America.
The company also announced it has been recognized in TIME’s 2026 ranking of America’s Top EdTech Companies, placing it 122nd out of 250 firms in the annual list.
The study reviewed over 2,500 companies across the U.S., giving 70% weight to financial strength and 30% to market influence.
The recognition reflects Classover’s broader transformation from a traditional online learning provider into a developer of integrated AI and robotics-based education tools.
"This ranking validates our strategic pivot toward 'embodied AI.' At Classover, we aren't just putting lessons on screens; we are building an integrated AI infrastructure that teachers, students and parents can all benefit from."
-Stephanie Luo, CEO, Classover
