On October 14, 2025, it was reported that Nebius Group (NBIS) holds a significant 28% equity stake in ClickHouse, a rapidly growing private artificial intelligence startup that is reportedly working towards an initial public offering (IPO). This news highlights a potentially valuable asset for Nebius beyond its core AI cloud business. ClickHouse has demonstrated strong performance, having more than quadrupled its annual recurring revenue over the past year and surpassed 2,000 customers, including prominent names like Hewlett Packard, Canva, and SonyLIV, as well as seeing strong adoption from major AI companies such as Anthropic and Meta Platforms. The potential IPO of ClickHouse is seen as a positive development for Nebius, as it would likely increase the value of its stake and be well-received by investors, especially given the current market appetite for AI-related IPOs. This revelation comes as Nebius Group's stock has already seen a significant surge in 2025, driven by high demand for AI computing capacity.
