Nscale is asking investors to value its business at roughly $30 billion while one of its planned AI computing sites waits for electricity. On Sunday, Bloomberg reported that some prospective investors favored $16 billion to $19 billion. Earlier that day, Microsoft was reported to have withdrawn from Nscale’s project in Loughton, Essex.
Nscale’s agreements make delivery schedules a financial issue. Customers can pay upfront, but the company still has to provide computing service to earn revenue. The electricity delays and valuation dispute expose different risks in Nscale’s expansion. Public reporting does not establish that Microsoft’s withdrawal caused investors to seek a lower price.
Nscale rents computing infrastructure to companies training and running AI models. Its customers include Microsoft and Anthropic. It is preparing a U.S. initial public offering, or IPO, in which investors would buy shares in the company. A company valuation describes the price placed on ownership; it is separate from the cash an offering raises.
Reuters, citing The Telegraph, reported that Microsoft had ended its agreement for Loughton. The newspaper did not specify Microsoft’s reason, and Microsoft declined Reuters’ request for comment. Grid officials had reportedly told Nscale that power would not be available until the 2030s.
Nscale told Reuters that its Microsoft relationship remained strong and that the London-area grid problem did not affect its other contracts. It said it remained committed to Loughton and was exploring alternative power sources. The public account does not disclose a cancellation payment or the value of that site’s contract.
The original September 2025 announcement promised 50 megawatts of AI capacity, expandable to 90, with 23,040 Nvidia GB300 graphics processors due in the first quarter of 2027. Those chips were intended to support Microsoft’s Azure services. The announcement described a future installation, not an operating fleet.
When a signed contract starts earning revenue
Nscale’s September 18 prospectus sets out how much signed business has become active. At August 31, it reported $103.4 billion in active and contracted total contract value, meaning revenue contracted across committed agreement terms. Only $2.6 billion related to active contracts.
SnowRock’s calculation puts the active share at about 2.5%. That percentage measures contract value associated with services that have started. It does not measure cash received, how busy the computers are or the probability that future projects will succeed. The larger total covers years of payments and includes services still to be delivered.
Nscale already operates computing sites. Its August figures included about 25,000 active graphics processors across five active data-center sites, against 461,000 processors active or contracted in total. The larger count includes the smaller one. Investors are financing an expansion from an existing business, with much of the promised fleet still ahead of it.
Nscale says contract terms start after successful delivery of computing clusters. It also generally receives customer prepayments at signing, helping to finance expansion. Those advances are recorded as deferred revenue until the company supplies service. A construction delay can therefore postpone earned revenue even after a customer has supplied cash.
Microsoft agreements provided for payments of up to $43.8 billion through December 2033. Separate Anthropic agreements provided for up to $44.6 billion. Both depend on delivery and service availability. Together, those stated amounts equal about 85.5% of August’s active and contracted total, using the rounded figures in the filing.
Those commitments cover multiple agreements and future periods. The prospectus does not separately price the Loughton contract. Anthropic’s agreements concern the Monarch Compute Campus in West Virginia, a different development whose own financing and delivery requirements appear in the filing.
Three different measures of Nscale’s business
| Measure | Published figure | What it counts |
|---|---|---|
| Active and contracted value | $103.4 billion | Revenue contracted across committed agreement terms, at August 31 |
| Active contract value | $2.6 billion | The portion associated with contracts already active, at August 31 |
| Recognized revenue | $140.6 million | Sales reported for the six months ended June 30, 2026 |
The figures cover different periods and cannot be added together. Active contract value is not annual revenue or cash received.

Sales are growing quickly from a small base. Nscale reported $140.6 million in first-half revenue, compared with $10.4 million a year earlier. Its $1.02 billion net loss included $457.1 million of losses from changes in the accounting value of financial instruments. The net loss therefore differs from cash spent building data centers.
The customer contracts described in the filing provide remedies when delivery fails. Anthropic’s agreements include termination rights for late batches of equipment and sustained service problems. Nscale warns that missed obligations can bring penalties and immediate cash demands. The contract terms make scheduled delivery part of Nscale’s obligation to customers, with consequences for both future sales and cash it may have to return.
Nscale has raised additional financing since that filing. Its September 25 announcement described $2.36 billion of convertible notes at closing and a further $1 billion from Nvidia expected in mid-November. Convertible notes begin as debt and can become shares. The later Nvidia contribution should not be counted as money already received.
Bloomberg’s reported investor range sits $11 billion to $14 billion below the roughly $30 billion target, a reduction of about 37% to 47%. These are competing valuation expectations, not a completed repricing. The amount investors ultimately supply will also depend on the number of shares sold and final offering terms.
Britain’s queue is dominated by very large projects
Loughton’s difficulty sits within a much larger connection problem. In a July consultation, Britain’s energy regulator, Ofgem, listed 315 proposed data-center projects seeking a combined 72,978 megawatts, or roughly 73 gigawatts. These are requested connections, not electricity already being consumed or a forecast that every project will be built.
SnowRock added the two largest size bands in Ofgem’s table. Their 206 projects accounted for 68,040 megawatts, or 93.2% of requested capacity. The remaining 109 projects accounted for 6.8%. A queue dominated by large campuses makes each developer’s readiness important to planning how much network construction is needed.
Large proposed campuses account for most requested power
| Ofgem’s project size band | Projects | Requested capacity |
|---|---|---|
| 0–10 MW | 11 | 76 MW |
| 10–50 MW | 47 | 1,370 MW |
| 50–100 MW | 51 | 3,492 MW |
| 100–500 MW | 166 | 36,632 MW |
| 500+ MW | 40 | 31,408 MW |
Ofgem’s July 2026 table lists 315 projects requesting 72,978 MW. The two largest bands account for 93.2% of that capacity, calculated by SnowRock. These are proposed connections. Band labels follow Ofgem’s table.

Eleanor Warburton, Ofgem’s director for energy system design and development, said in July that “consumers should not bear the risks created by speculative projects taking up space in the system.” The regulator wants developers to demonstrate financial capability, commercial progress and procurement activity before retaining scarce connection capacity.
Ofgem proposed a commitment fee that would be refunded when a project receives electricity and forfeited if it leaves the queue early. Its consultation page currently says it is closed and awaiting a decision. These remain proposals. The documents do not establish that Nscale’s Loughton application was speculative.
Colm Murphy, director of connections at the National Energy System Operator, wrote in August: “For too long, a place in the connections queue did not mean a realistic path to connecting.” NESO’s October 1 account identifies planning consent, network construction, supply chains, financing and developer readiness as separate requirements.
A building and its chips run on different schedules
The International Energy Agency’s Electricity 2026 report estimates that new grid infrastructure can take five to 15 years to plan, permit and complete, compared with one to three years for a data center. It also describes faster, conditional connections that may restrict consumption at certain times, a tradeoff for customers needing dependable computing capacity.
The Bank of England’s July financial stability report adds another timing problem: chips have short, uncertain useful lives. Rapid improvements can reduce their economic value, although shortages and demand for older equipment may extend it. Buildings can also lose value if they cannot support newer chips.
The Bank says many credit investors favor longer lending periods than the useful lives expected for AI chips. Shorter loans could align repayment with equipment life but be less attractive to lenders. How lenders, developers and customers share that exposure depends on their agreements. This is a sector-wide assessment, rather than a finding about Loughton.
Nscale’s final offering terms and updated contract disclosures will show what investors ultimately accept. At Loughton, the company says it is exploring alternative power, but the reporting reviewed here identifies no replacement supply or revised service date. Its original announcement scheduled chip delivery for early 2027; Sunday’s report puts grid electricity years later.
Common questions
What does Nscale do?
Nscale supplies computing infrastructure and cloud services for training and running AI models. Customers rent access to graphics processors, networks and related services instead of building every part themselves.
Has Nscale’s IPO valuation been cut?
No final IPO valuation has been announced in the reporting reviewed here. Bloomberg reported on October 18 that Nscale sought roughly $30 billion and some prospective investors favored $16 billion to $19 billion.
Is a $30 billion valuation the amount Nscale would raise?
No. A valuation puts a price on ownership of the company. An offering’s proceeds depend on its share price, how many shares are sold and whether the company or existing shareholders receive the money.
Did Microsoft leave Nscale’s Loughton project?
Reuters reports that Microsoft ended the Loughton agreement.
Why did Microsoft withdraw?
Microsoft’s reason was not disclosed.
Does the withdrawal cancel every Nscale contract with Microsoft?
Nscale says its other Microsoft contracts are unaffected.
What had Nscale planned to build in Loughton?
Its September 2025 announcement described 50 megawatts of AI capacity, expandable to 90, initially housing 23,040 Nvidia GB300 processors due in the first quarter of 2027.
What is total contract value?
It counts revenue contracted over committed agreement terms. Nscale’s prospectus reported $103.4 billion of active and contracted value at August 31. That total is separate from sales already recognized in financial statements.
How much of Nscale’s contract value was active?
About 2.5%, calculated by dividing the reported $2.6 billion of active contract value by $103.4 billion of active and contracted value. This does not measure computer utilization or cash received.
Which customers account for most disclosed contract value?
Nscale’s disclosed Microsoft and Anthropic agreements together represent about 85.5% of August’s active and contracted value. Their stated maximum payments depend on delivery and service availability.
What does a take-or-pay contract mean?
It generally requires a customer to pay for agreed capacity whether it uses all of it or not. The agreement can still require delivery and service standards and provide remedies if the supplier misses them. Nscale says contract terms start after successful delivery.
Can a power delay cost an AI infrastructure company money?
It can postpone service revenue, add financing costs or trigger contractual remedies, even where a customer has paid upfront. The specific outcome depends on the agreements. No quantified Loughton cancellation payment was disclosed in the reporting reviewed here.
Can Nscale power Loughton another way?
No replacement supply has been confirmed.
Are Ofgem’s proposed data-center connection fees already in force?
The consultation page says it is closed and awaiting a decision. The proposal would charge a commitment fee, refundable at connection and forfeited for an early queue exit.
What would show that Nscale’s plans are progressing?
Nscale expects an additional $1 billion Nvidia contribution in mid-November, according to its September 25 financing announcement. Other useful developments would be final IPO terms, updated contract disclosures and a confirmed power supply and service timetable for Loughton.
