Microsoft Just Piled Onto the Bad News for CoreWeave, Oracle, and Nebius

As Microsoft ramps up production of its custom AI accelerator chip (Maia 300) in 2027, it plans to shift more compute workloads in-house. This strategic pivot, combined with rising borrowing costs and investor hesitancy, poses significant challenges for neocloud companies like CoreWeave and Nebius, which are heavily dependent on major customer contracts and external financing.
