Microsoft steps back from extra Texas capacity with Nscale ahead of IPO

What changed

According to a person familiar, Microsoft opted not to renew its arrangement at the Ward County, Texas site ahead of London-based Nscale's S-1 submission in September. Late last year, Nscale set up about 240 megawatts of computing capacity for Microsoft at that location and indicated the software company had the option to add 700 megawatts.

On Thursday, Nscale revised its 2025 release and removed mention of that option. A company spokesperson said the potential add-on was closer to 500 megawatts and offered no further details. Microsoft declined to comment.

Why the Texas site stalled

The person said Microsoft did not proceed with the Ward County plan because the site was still waiting on regulatory clearance for an energy connection. On an earnings call Wednesday, Ionic Digital told investors it received provisional approvals for the site from the Texas grid operator. Ionic Digital, which manages the leased facility where Microsoft took the initial 240 megawatts, did not immediately provide comment when asked.

The Financial Times previously reported that Microsoft declined the extra capacity. Separately, Microsoft exited a data center agreement in the UK last month, while it continues to have arrangements with Nscale in Portugal and Norway.

The broader backdrop

Nscale is preparing to debut as a fast growing neocloud centered on AI computing. Since the S-1 filing, enthusiasm around AI data centers has cooled amid concerns about heavy borrowing and mounting political resistance. A number of investors have criticized Nscale's roughly 30 billion dollar IPO target valuation.

Politics just added pressure. Frustration with data centers surfaced as a major theme in this week's midterms. In Texas, governor-elect Gina Hinojosa prevailed over Republican Greg Abbott in the wake of repeated calls to pause data center construction.

The investor angle

Funding for neocloud builders often hinges on commitments from top tier tech customers. Nscale's filings show Microsoft accounts for about 42 percent of 103 billion dollars in contracted value. Its other big customer, Anthropic PBC, is spending heavily on compute but does not carry Microsoft's established credit profile.

The bottom line: a marquee customer opted not to add capacity at a key site, Nscale revised language around that option, and the sector's political and financing headwinds are rising. Investors weighing Nscale's IPO now have a clearer picture of concentration risk, contract dynamics, and the policy climate shaping future build outs.
