Microsoft re-evaluates new cloud strategy and tightens oversight of third-party compute partners

According to a Bloomberg report on November 5, 2026, citing people familiar with the matter, Microsoft is rethinking its strategic bets in the neocloud space. Citing data center delays, regulatory resistance and rising costs, the company has begun tightening oversight of third-party compute partners such as Nebius, IREN and Nscale, pulling out of projects it deems too risky and debating internally whether to sign any more neocloud deals. The shift was already visible at Microsoft's recent earnings call, where CFO Amy Hood publicly flagged delivery delays from third-party compute providers three times as a disruptor to the company's spending plans. Microsoft's prior commitments in the space were substantial: up to $43.8B to Nscale, up to $19.4B to Nebius, over $10B to CoreWeave, and roughly $9.7B to IREN. The move sent shockwaves through the neocloud sector, with shares of IREN and Nebius each falling around 20% at one point after the news. One of the recent issues surfaced involves a cabling fault at an IREN development project in Texas. Because data center servers rely on intricate fiber-optic interconnections, cabling problems can directly affect operations.
