Microsoft exits Nscale data centre project ahead of IPO

The departure of Microsoft from the Lawton project lands at a delicate moment: a startup heading toward IPO with roughly 85% of contracts tied to Microsoft and Anthropic now faces a visible anchor-tenant exit, even if the filing's customer concentration was already disclosed. The power-timing constraint in Essex and the Norway buildout lag point to execution risk that sits outside Nscale's control, which matters more for a capital-intensive cloud provider than for a software issuer. Whether the remaining Microsoft and Anthropic exposure is renegotiated or backfilled is the open question, and the IPO process itself will be the first place that answer surfaces.
