CoreWeave: The Leveraged Shovel-Renter
CoreWeave ran the oldest play in any gold rush: sell the shovels. It bought Nvidia GPUs by the thousands and rented them to AI companies desperate for compute, IPO'd in March 2025, and raised more than $25 billion in debt and equity in roughly 18 months, including high-yield notes at around 9 percent. The pitch was clean: chips are scarce, demand is insatiable, and CoreWeave sits in the middle taking the premium. But almost all of that revenue traced back to just two customers, both knotted into the same circular AI financing cluster.
For founders and operators, this is a case about the math underneath a boom: what happens when you fund explosive growth with expensive debt and a tiny handful of anchor customers. It sharpens the decision of how much concentration and leverage you can carry before a single customer's roadmap change becomes your problem, not theirs.
