DDN projects revenue doubling to $1B in 2026 on AI storage boom

The unglamorous parts of the AI stack keep quietly minting winners, and this week it is a 28-year-old storage vendor most people outside data centers have never heard of. According to a Forbes profile by Iain Martin, DDN is on track to double its revenue to roughly $1 billion in 2026, up from about $500 million a year earlier and $400 million in 2024, on the back of contracts with Elon Musk's xAI, Nvidia, GPU cloud Lambda, and national governments building their own AI supercomputers.

The mechanics are less mysterious than the headline. Training and serving large models thrashes storage in ways ordinary enterprise arrays were not designed for, and DDN, founded in 1998, has spent its whole existence on parallel file systems for HPC and public-sector customers. That head start maps neatly onto AI clusters. The company says its platform sits behind more than 500,000 Nvidia GPUs, including the 100,000-GPU xAI Colossus system.

The money story tracks the customer story. In January 2025, Blackstone put $300 million into DDN at a $5 billion valuation, the first outside capital co-founders Alex Bouzari and Paul Bloch had taken in more than two decades of profitable private ownership. Forbes reports the pair still hold roughly 40% each, stakes now worth around $2 billion apiece.

The honest caveat is that a doubling forecast is the company's own guidance in the piece, not audited results, and much of the growth is tethered to a small handful of very large AI buildouts whose capex plans can move fast in either direction. What the reporting does not spell out is customer concentration, gross margins, or how DDN's parallel-storage pitch holds up as rival vendors push into the same AI accounts.

Still, the strategic read is worth sitting with. When the picks-and-shovels layer of an infrastructure boom starts producing billion-dollar revenue lines from decades-old specialists, it is usually a sign that the bottleneck they solve has become load-bearing. If the sovereign AI orders keep landing and Blackstone eventually pushes for an IPO, DDN could end up as the storage counterpart to the GPU story everyone already knows.
