Nscale: A Major IPO Test for AI Infrastructure
The UK-based cloud provider Nscale filed an IPO prospectus with the SEC on Friday and aims to trade on the NYSE under the ticker NSCL. The underwriters are Goldman Sachs, J.P. Morgan, and Morgan Stanley. Revenue for the first half of 2026 rose to $140.6 million from $10.4 million a year earlier, while the net loss expanded to $1.02 billion. Remaining contract obligations total $56.4 billion, although more than half of the revenue was generated by a single client. According to media reports, the company is looking to raise up to $3 billion at a valuation of up to $35 billion, compared to $14.6 billion in the March Series C round. Concurrently, Nscale has secured a convertible loan from Nvidia.
For venture funds, this represents the first autumn indicator of how public investors will assess a capital-intensive model with contracted demand, high client concentration, and dependency on a single GPU provider.
Holtec and the IPO Window: Selectivity Over Euphoria
Holtec Nuclear, once regarded as the key IPO of September, has postponed its offering. The backdrop is unfavorable: X-energy is trading approximately 37% below its April offering price, while Standard Nuclear is down 21%. The IPO window has not closed but has narrowed:
- This week, Bamboo Insurance ($665 million at a $3.3 billion valuation) and defense materials manufacturer Amaero ($53 million) are expected;
- The biotech company Electra Therapeutics, which raised $350 million, is trading about 12% below its offering price;
- Motive has withdrawn its IPO application and secured over $1.3 billion in growth financing from General Catalyst—private equity is replacing the exchange;
- Revolut is considering a dual listing in New York and London with a valuation of up to $200 billion.
“AI Pause” and the Fed Rate: A Dual Filter for Valuations
Anthropic’s CEO Dario Amodei published an essay calling for a coordinated slowdown in scaling model capabilities. He was supported by Sam Altman and leaders from other major tech companies. The market responded with a sell-off in semiconductors, but by the end of the week, the Nasdaq gained 0.7%, while the Dow lost 1.7%.
Industry analysts highlight the implications for venture investments: longer model release cycles, potential shifts in data center commitments, extended exit timelines, and increased pressure on LPs. Competition is shifting from 'raw' performance to distribution, reliability, and cost, favouring larger players. Concurrently, there are calls to regulate owners of over 5% of computing power, akin to systemically important banks.
OpenAI and Anthropic: Trillion-Dollar Valuations, Different Paths
Investors have proposed a round for OpenAI at an estimated valuation of around $1.2 trillion—41% higher than March's $852 billion, when the company raised $122 billion. There are no formal negotiations according to media reports; some proposals involve employees selling shares. The annual revenue has exceeded $40 billion, with an IPO expected in 2027. Anthropic, valued at $965 billion in May, is still preparing its listing marketing for Nasdaq in mid-October. Its listing will set the public multiplier for the entire AI sector.
Megarounds and New Unicorns: Capital Concentration
- Temporal – $550 million Series E at a valuation of $12.55 billion; an AI agents platform.
- Fab2 – $500 million Series A for the mass production of compact chip factories.
- Suniva – $835 million in debt and equity for solar cell production in the US.
- Ridgeline – $250 million at a valuation of $1.45 billion; Cornelis Networks – $205 million for AI networking solutions.
- Penelope Health – $100 million for automating administrative processes for doctors.
Just a week earlier, Cognition raised $2 billion at a $48 billion valuation, and the Boring Company secured $3 billion at a $23 billion valuation. Median Series A and B rounds remain moderate, highlighting the growing gap between category leaders and other startups.
Debt Instead of Equity: Chips and Energy as Collateral
Funding for AI infrastructure is increasingly moving to the credit market. A consortium of ten banks is providing $22 billion secured by TPU and client contracts from Crux AI—a cloud project backed by Blackstone and Alphabet with $5 billion in equity. Bloom Energy has reached an agreement with Brookfield for $25 billion in project financing for data center energy supply. Nvidia will invest $2 billion in Brookfield’s $10 billion infrastructure AI fund. For venture funds, this means less dilution of shares in portfolio companies, but greater sensitivity to interest rates.
M&A: Signed Does Not Mean Closed
Deals remain a secondary channel of liquidity, but closing timelines are elongating. The acquisition of Hugging Face by Nvidia for $12.9 billion is not expected to close until the first half of 2027. Signed but not completed deals include Visa – BioCatch ($2.4 billion), Analog Devices – Alif Semiconductor ($1.35 billion), Bending Spoons – Miro ($1.36 billion), and Dynatrace – Arize AI ($915 million). SoftBank has agreed to acquire the Robotics and AI Institute, with the deal currently under review in the US. SPACs are making a comeback: nuclear tech developer HGP is merging with Meshflow at an estimated $1.2 billion valuation.
Europe, Asia, and Emerging Markets
- United Kingdom: Emulate, founded in August by former Google DeepMind employees, is discussing a seed round of up to $700 million at a valuation of around $3.7 billion; leading investors include Index Ventures and Lightspeed. ElevenLabs is preparing a Series E of over $500 million with potential participation from the Scaleup Europe Fund.
- Netherlands: Euclyd raised €200 million in a Series A round for inferencing chips; leading the round is Samsung.
- India: The India Deep Tech Alliance has pledged to invest $3 billion, with $250 million allocated in the first year.
- China: CATL is creating a venture fund of $860 million for AI and robotics; its robo-taxi division Hello raised about $100 million.
- Latin America: Brazilian VOLL received $140 million from Warburg Pincus.
What This Means for Venture Investors and Funds
- Exits are shifting. The postponed IPO of OpenAI and Holtec’s pause extend the liquidity horizon—DPI planning needs to be reassessed.
- Nscale and Anthropic will set the multipliers. Their reception by the public market will determine late-stage valuations for 2027.
- Regulatory risk has become an investment factor. Security audits and potential computational limits need to be factored into due diligence.
- The capital structure is changing. Debt backed by chips and contracts reduces dilution but requires sustainable unit economics at a 4% rate.
- The team premium has reached its limit. Seed rounds of hundreds of millions without a product raise the bar for the next round and increase the risk of down-rounds.
The venture market remains liquid, but is paying for proven demand, control over scarce resources, and capital discipline. These criteria will shape startup and venture investment news through the end of the third quarter.
