CoreWeave's DDTL 4.0 closed at a fixed rate of approximately 5.9%, with investment-grade ratings from Moody's. Prior facilities ran between 11 and 15%. When the marginal cost of debt for a GPU cloud operator drops by roughly half, the unit economics of leasing change materially.
Every prior analysis treating CoreWeave's leverage as structurally dangerous was pricing the business at 11% weighted average. That assumption is now stale on new draws. The facility is backed by Meta contracts worth at least $19.2B, including a new $5B+ deal signed in early 2026 that hadn't previously been reported Yahoo Finance, which also quietly addresses the customer concentration bear case. The credit story is cleaner than it was six months ago.
The risk that remains is timing. CoreWeave can initially draw $7.5B, with the option to expand to $8.5B only as data centers reach stable operating levels. That contingency clause is the honest part of this deal. Q1 revenue was guided well below street, and the full-year $12-13B target requires margins to trough now and recover to low double digits by Q4.
