Grid delays spark Microsoft exit as investors demand Nscale IPO price cut to $16B-$19B

British AI cloud provider Nscale is encountering significant resistance from potential investors regarding its proposed initial public offering valuation. According to Bloomberg, a group of investors is urging the company to lower its target from approximately $30 billion to a range of $16 billion to $19 billion to attract buyers.

No final decisions have been made on the valuation, and Nscale has not yet formally begun marketing its shares for the planned New York Stock Exchange listing. The company filed for its IPO in September, aiming to raise up to $3 billion under the ticker symbol NSCL.

Valuation pressures and contract details

Nscale’s last private funding round valued the firm at about $15 billion, while The Telegraph previously estimated a possible listing value of up to $35 billion. The current push for a lower valuation comes as the market for AI infrastructure listings appears to be cooling. Bloomberg reported that only a small portion of Nscale’s $103.4 billion in signed and active contracts, recorded at the end of August, are currently operational.

Microsoft and Anthropic account for roughly 85 percent of Nscale’s total contract value. The valuation target is also critical for existing backers, including Third Point, which led a $3.36 billion pre-IPO convertible note offering in September. These notes convert into shares at a discount, with the conversion price capped at a $30 billion valuation. An additional $1 billion from Nvidia is still pending.

Operational challenges and market context

Investor concerns are driven by project delays and a recent high-profile exit by a major client. Nscale’s flagship data center site in Norway is reportedly running about six months behind schedule. Additionally, Microsoft terminated its agreement to be the primary tenant at Nscale’s planned facility in Loughton, Essex. Grid operators do not expect to supply power to that site until the 2030s. Microsoft’s exit occurred weeks before the planned listing.

This development follows earlier reporting by Threat Times on October 19, which noted that Microsoft exited the Nscale AI cloud deal ahead of the UK firm’s expected IPO. The broader market environment for similar firms has also been difficult. Australian data center operator Firmus dropped its IPO earlier this month due to weak investor demand. Meanwhile, shares in CoreWeave, a prominent listed AI cloud company, fell approximately 25 percent last week, marking their worst performance since November.

What should you do?

Security and technology professionals monitoring the AI infrastructure sector should track Nscale’s official communications for updates on its IPO timeline and valuation adjustments. Organizations relying on AI cloud services should assess their vendor concentration risks, particularly given the heavy reliance on Microsoft and Anthropic for Nscale’s contract volume.

WATCH FOR:

• Official statements from Nscale regarding its IPO marketing phase and valuation targets.
• Updates on power grid infrastructure timelines for Nscale’s Essex and Norway facilities.
• Market performance of other listed AI infrastructure companies like CoreWeave.
• Changes in Nscale’s contract portfolio as existing clients adjust their commitments.
