Nscale IPO Faces Investor Resistance as $30B Valuation Deemed Too High Amid Market Cooling

British AI cloud firm Nscale is facing mounting investor resistance as it prepares for its upcoming New York IPO, with backers questioning whether the company's targeted $30B Nscale valuation is justified given recent operational setbacks and cooling market conditions for AI infrastructure listings1

Investors Push for Lower Valuation

A group of investors told Bloomberg that a Nscale valuation between $16B and $19B would be more realistic and likely to attract buyers for the AI infrastructure company1

. The investor pushback represents a stark contrast to the company's ambitions, with some reports suggesting the listing could reach as high as $35B. Nscale, which provides computing power for AI model training and running AI models, filed for its Nscale IPO in September and plans to list on the New York Stock Exchange under the ticker NSCL, aiming to raise up to $3B1

. The company's last private funding round valued it at approximately $15B, making the proposed $30B target a doubling of its previous assessment.

Operational Setbacks Fuel Concerns

The investor resistance stems partly from significant operational challenges facing the AI infrastructure company. Microsoft has withdrawn from a deal to be the main tenant at Nscale's planned data center in Loughton, Essex, after grid operators indicated they could not supply power to the site until the 2030s1

. Microsoft's exit came just weeks before the planned US IPO, raising questions about the company's ability to secure major clients. Additionally, the company's flagship Norwegian facility is running approximately six months behind schedule, further complicating the listing plans1

. These delays at critical sites have intensified concerns about execution risk.

Contract Portfolio and Client Concentration

According to its IPO filing, Nscale had $103.4B in signed and active contracts at the end of August, though only a small portion was already operational1

1

. Microsoft and Anthropic together account for roughly 85% of the total contract value, creating significant client concentration risk for potential investors. This heavy reliance on two major customers raises questions about revenue diversification and long-term sustainability, particularly given Microsoft's recent withdrawal from the Loughton project.

Pre-IPO Funding and Conversion Terms

In September, Nscale raised $3.36B in pre-IPO convertible notes led by Third Point, with an additional $1B expected from Nvidia1

. These convertible notes are structured to convert into shares at a discount, with the conversion price capped at a $30B valuation. This means the final Nscale valuation directly impacts existing backers, including Norwegian investment company Aker, a major shareholder whose stock dropped nearly 5% following news of the valuation dispute2

2

. The convertible note structure creates tension between existing investors seeking a higher valuation and new investors demanding more attractive entry points.

Cooling Market for AI Infrastructure

The broader market environment for AI infrastructure listings has deteriorated significantly, adding pressure on Nscale's pricing strategy. CoreWeave, the most prominent listed AI cloud company, saw its shares plummet approximately 25% last week in its worst performance since November1

1

. Australian data center operator Firmus recently abandoned its IPO entirely due to weak investor demand, signaling broader caution in the sector1

1

. These market conditions suggest investors are becoming more selective and demanding better valuations before committing capital to AI infrastructure plays.

What This Means Going Forward

No final decisions have been made on the listing terms, and Nscale has not yet formally begun marketing its shares to potential investors1

. The company had not publicly responded to the Bloomberg report at the time of publication. Market observers will be watching whether Nscale adjusts its valuation expectations or proceeds with its original target, risking a weak reception. The outcome could set important precedents for other AI infrastructure firms considering public listings, particularly those with similar operational challenges or client concentration issues. Investors should monitor whether Nscale can resolve its Norwegian facility delays and secure replacement tenants for the Loughton data center before finalizing its IPO pricing.
