NVIDIA is not just a supplier and investor in CoreWeave; it also acts as a financial backstop. By guaranteeing it will purchase any of CoreWeave's excess, unsold GPU compute, NVIDIA de-risks the business for lenders and investors, ensuring bills get paid even if demand from customers like OpenAI falters.
The AI ecosystem appears to have circular cash flows. For example, Microsoft invests billions in OpenAI, which then uses that money to pay Microsoft for compute services. This creates revenue for Microsoft while funding OpenAI, but it raises investor concerns about how much organic, external demand truly exists for these costly services.
Instead of bearing the full cost and risk of building new AI data centers, large cloud providers like Microsoft use CoreWeave for 'overflow' compute. This allows them to meet surges in customer demand without committing capital to assets that depreciate quickly and may become competitors' infrastructure in the long run.
CoreWeave's origin as an Ethereum mining firm that pivoted to AI highlights a broader trend. Many players in the AI space are recent converts from the crypto industry, suggesting their motivation is chasing profitability and hype cycles rather than a long-term, foundational belief in the technology. This opportunism can be a warning sign for investors.
By funding and backstopping CoreWeave, which exclusively uses its GPUs, NVIDIA establishes its hardware as the default for the AI cloud. This gives NVIDIA leverage over major customers like Microsoft and Amazon, who are developing their own chips. It makes switching to proprietary silicon more difficult, creating a competitive moat based on market structure, not just technology.
Large tech companies are creating SPVs—separate legal entities—to build data centers. This strategy allows them to take on significant debt for AI infrastructure projects without that debt appearing on the parent company's balance sheet. This protects their pristine credit ratings, enabling them to borrow money more cheaply for other ventures.
Companies like CoreWeave collateralize massive loans with NVIDIA GPUs to fund their build-out. This creates a critical timeline problem: the industry must generate highly profitable AI workloads before the GPUs, which have a limited lifespan and depreciate quickly, wear out. The business model fails if valuable applications don't scale fast enough.
