Microsoft Passes on Expanding Its Texas Data Center Deal With Nscale

A tens-of-billions option, declined

The Microsoft Nscale deal will not grow the way Nscale hoped. Microsoft will not exercise an option to more than double the size of its existing agreement with AI cloud provider Nscale to rent more computing power at a Texas data center, according to a person familiar with the matter. The Financial Times first reported the news on Thursday, November 5, 2026, and Reuters confirmed it. A potential extension would have been worth tens of billions of dollars for Nscale.

The decision is not new, even if the news is. The person familiar with the matter said Microsoft made the decision several months ago, before Nscale filed for its IPO in September, and added that the existing Texas contract with Microsoft is not affected. That timing matters. Nscale went public with investors believing the expansion was plausible, and Microsoft had already decided otherwise.

What the existing deal covers

The two companies struck their deal last year, under which Nscale would deploy around 200,000 Nvidia AI chips under an expanded agreement with Microsoft across its data centers in Europe and the US. That part stands. Microsoft is still a major Nscale customer, and the decision concerns only the option to expand further at the Texas site.

Nscale said in its IPO filing that between September 2025 and April 2026 it signed statements of work with Microsoft worth up to about $43.8 billion through December 2033, excluding optional extensions. The source said the decision not to exercise the option has no impact on Nscale's total contract value of about $103 billion as disclosed in the IPO filing, and that Nscale was already in discussions with several major customers for the rest of the data center capacity in Texas.

The second pullback in weeks

This is the second time in weeks that Microsoft has stepped back from an Nscale project. Weeks earlier, Microsoft pulled out of a deal to anchor Nscale's flagship data center project in Loughton, Essex, after power connection delays pushed its expected supply date into the 2030s. A data center without power on a usable timeline is a hole in the ground, and Microsoft was not willing to wait.

Power is the quiet constraint on the whole AI buildout. Data centers need enormous amounts of electricity, grid connections take years, and the gap between announced capacity and energized capacity is growing. The neocloud slump hitting CoreWeave, Nebius and AirTrunk reflects the same pressure from the market side: investors are asking whether the buildout can pay for itself, and whether the demand is as certain as the announcements suggest.

Who fills the gap

Reuters reported last month that Nscale was in talks to sell AI computing power to Anthropic in a new deal that could be worth about $45 billion. If that closes, it would more than replace the Microsoft expansion that did not happen, and it would diversify a customer base that currently leans heavily on one buyer. That is presumably the story Nscale will tell investors now: the capacity is still there, and other buyers want it.

The bigger picture is a market recalibrating. Google is betting $15 billion on Malaysia as its next cloud and AI hub, and big tech is on track to spend more than $720 billion on data centers in 2026. The money is still flowing, but the decisions are getting more selective. Microsoft declining an option it already held is a sign that even the biggest spenders are choosing where to expand, rather than expanding everywhere at once.

For Nscale, the test is whether the Texas capacity finds a buyer at the same scale, and whether the Anthropic talks turn into a signed deal. For the rest of the industry, the lesson is simpler: options are not commitments, and a data center deal is only as solid as the power behind it.
