CoreWeave's AI Expansion Accelerates but Margin Pressure Mounts

What happened

CoreWeave's aggressive AI infrastructure buildout is driving revenue and backlog growth, with Q1 2026 revenue reaching $2.1 billion and RPO swelling to $98.8 billion. However, the expansion is funded by increasingly costly debt, as net interest expense hit $536 million in Q1, contributing to a GAAP net loss of $740 million. The latest DDTL 5.0 facility priced at SOFR+4.50% with tight covenants, including a 1.35x DSCR and contract-linked defaults, signals rising financing costs and creditor protections. Insider selling by top executives in May 2026, including CEO Intrator and CSO Venturo, at prices around $102-$117 further underscores caution. The market is now questioning whether revenue growth can outpace escalating capital costs and whether execution risks will erode margins.

Implication

Investors should wait for evidence that CoreWeave can convert its $98.8 billion backlog into cash without further margin compression. The company's heavy reliance on debt at increasing spreads, coupled with extreme customer concentration and covenant-laden financing, leaves little room for error. Near-term catalysts like active power expansion and new contracts are offset by risks of delivery delays and potential covenant breaches. The insider selling cluster adds to the cautionary tone. We maintain a WAIT rating with an attractive entry around $80, implying significant downside from current $103.8.

Thesis delta

The news of margin pressure aligns with our existing concerns; no fundamental shift in thesis. However, the insider selling cluster after the Q1 report adds a new layer of caution, reinforcing our stance that the stock lacks a margin of safety and that patience is warranted until cheaper financing or better execution emerges.
