Current Startup and Venture Capital News for September 17, 2026: Mega Round for Temporal in AI Infrastructure, Unicorns Exein and Open Cosmos, Semiconductor Deal EUCLYD, Wave of Rounds in "Physical AI" in China, FOMC Meeting, Holtec IPO, and Anthropic Listing Preparations

By mid-September 2026, the global venture market is exhibiting a notable shift: capital is moving away from “wrappers” around language models towards infrastructure that makes artificial intelligence reliable, cost-effective, and applicable in the physical world. Over the past 48 hours, venture funds have closed a series of major funding rounds — from $550 million in Temporal to €300 million in Open Cosmos — while Europe welcomed two new unicorns in a single day. At the same time, investors are re-evaluating capital cost models: the FOMC meeting on September 16, where markets priced in over a 90% probability of the first rate hike since 2023, sets a new framework for late-stage startup valuations.

Key venture agenda topics for Thursday, September 17, 2026:

• Temporal's Mega Round. $550 million at a valuation of $12.55 billion — infrastructure for agent-based AI is becoming an asset class of its own.
• New Unicorns in Europe. Italian Exein ($1.7 billion) and British Open Cosmos (over $1 billion) confirm the demand for cybersecurity and space.
• Semiconductors and "Physical AI". EUCLYD raises over €200 million, while China funds robotics and chip inspection.
• Macrofactor. The FOMC and expensive venture debt are altering the mathematics of late-stage rounds.
• IPO Window. Holtec and Orion180 pricing, anticipation of Anthropic’s prospectus and Oura's listing.
• Russia and CIS. The market has shrunk by nearly half, with capital concentrated in the top five deals.

Deal of the Day: Temporal Raises $550 Million for AI Agent "Reliability"

Temporal, a platform developing durable execution infrastructure for distributed applications and AI agents, has closed a $550 million Series E round at a valuation of $12.55 billion. The round was led by Lightspeed, with co-investors including Wellington Management, Growth Equity at Goldman Sachs Alternatives, and Tiger Global; participating investors included T. Rowe Price and SV Angel, while returning investors such as a16z, Sequoia, Index, and GIC also took part.

The dynamics are telling: in February 2026, the company was valued at $5 billion during Series D, meaning its valuation has more than doubled in seven months. The justification lies in operational metrics that are rarely seen in startups of this scale:

1. Annual revenue exceeded $250 million, with over 200% year-on-year growth;
2. Net Revenue Retention (NDR) has remained above 200% since February;
3. In August, the platform processed 1.9 trillion billable actions, an increase of over 350%;
4. The number of paying customers reached 4,300 (+139%), including OpenAI, Netflix, Snap, NVIDIA, and JPMorgan Chase.

For venture investors, Temporal is a marker of a new thesis: it is not the one who trains the best model that wins, but the one who controls how models execute multi-step processes in production.

Europe: Two New Unicorns in One Day

Exein – The Most Valued Cybersecurity Startup in Europe

Rome-based Exein has raised $270 million at a valuation of $1.7 billion in an oversubscribed round led by Headline. The deal included participation from Sofina, Goldman Sachs, the European Investment Bank Group, KfW Capital, and T.Capital, along with previous investors Balderton, HV, and Lakestar. The total amount of capital raised has surpassed $600 million, the valuation has increased 30 times in two years, and ARR in the first half of 2026 quadrupled.

The company protects “physical AI” — robots, drones, autonomous transport, and industrial devices — at the core operating system level. Its technology covers over 2 billion connected devices, with about half of its revenue coming from the Asia-Pacific region. The funds will be used for expansion into the US, M&A, and developing its proprietary foundational model for machine security.

Open Cosmos – A Profitable Space Unicorn

British satellite manufacturer Open Cosmos has closed a Series C round of €300 million (approximately $348 million) at a valuation of over $1 billion. The round was led by Lightrock and ETF Partners; it included participation from the BCI pension fund, Institut Català de Finances, Entrepreneurs First, Phoenix Court, and the UK NSSIF, with Claret Capital providing venture debt. The company launches up to one satellite per day across four factories, has shown profitable growth for five consecutive years, and secured contracts totaling over $370 million in three and a half years. The round was oversubscribed and intentionally focused on European investors — a signal that sovereign space infrastructure is becoming a priority for continental capital.

Semiconductors: EUCLYD Targets Inference Costs

Eindhoven-based startup EUCLYD has raised over €200 million in a Series A round co-led by Samsung, Somerset Capital Partners, Scaleup Europe Fund managed by EQT, and Innovation Industries. Former ASML CEO Peter Wenning has become the chairperson of the board. The company develops specialized ASICs and datacenter-level systems that reduce energy consumption and memory bandwidth requirements when servicing large models. The thesis is straightforward: if inference becomes the largest computational load, the economics of “per token” turn into a separate semiconductor opportunity, irrespective of which model wins.

Asia: China Dominates "Physical AI" Rounds

The Asian trading day brought a cluster of deals united by the common logic — funding components and operating systems for robots, rather than demonstration prototypes:

• ENCOS (Nanjing) – over 300 million yuan in a Series B led by CITIC Goldstone for manufacturing integrated robotic joints and manipulators;
• Yincheng Intelligence (Shanghai) – around 100 million yuan in a Series A alongside a comparable-sized order from SF Express for sorting robots;
• Kangwei Vision (Shenzhen) – approximately 100 million yuan for optical inspection of AI server boards;
• Nutshell Therapeutics – a C1 round for tens of millions of dollars from Trustbridge and Decheng with a candidate already in clinical phase I.

The picture is completed by Hong Kong's Qupital with $300 million in commitments in trade finance, Stockholm's Tandem Health with $100 million in Series B from EQT, and Tokyo's Yoom with its first external round of ¥700 million for orchestrating AI agents in corporate processes.

Macro: FOMC, Venture Debt, and New Capital Price

The FOMC rate has been held in the range of 3.50–3.75% since December 2025; however, inflation in the US remained at 3.4% as of August against the backdrop of an energy shock caused by the conflict in the Middle East. Ahead of the meeting on September 16, futures priced in about a 93% probability of a 25 bps hike — the first since 2023. For the venture market, this implies a "costly money for a long time" scenario: floating credit lines tied to SOFR are being revalued every 90 days, and every 25 bps adds approximately $25,000 in annual costs for every $10 million of debt. Late-stage funds are already adjusting multiples, while companies with growing metrics, like Temporal, continue to attract capital at premium valuations.

IPO: The Window is Open, But Selectively

2026 is heading towards the strongest initial public offering market results since 2021: since the beginning of the year, 331 applications have been submitted, with 280 deals completed. On Thursday, September 17, pricing for two listings on Nasdaq is scheduled: nuclear company Holtec is offering 50 million shares at $15–18 (approximately $850 million), while insurer Orion180 aims to raise up to $340 million at a valuation of around $1.7 billion. Smart ring manufacturer Oura, which submitted its application on September 3, expects to list closer to the end of the month.

The highlight of the season is Anthropic. After a confidential S-1 filing in June and a Series H round at a valuation of $965 billion, the company is reportedly preparing a public prospectus for the end of September and a roadshow by mid-October with a target valuation of up to $2 trillion. Annual revenue as of the end of July exceeded $65 billion. Public financial data from the AI market leader is set to serve as a benchmark for reevaluating the entire private AI ecosystem.

Russia and CIS: Concentration Instead of Growth

The Russian venture market shrank by 48% year-on-year in the first half of 2026, down to 4.6 billion rubles, with the number of active investors falling from 50 to 33. Private funds accounted for 67% of the volume (3.1 billion rubles in 21 deals), while corporate investments dropped by 54% to 0.4 billion rubles. The top five deals accounted for about 60% of the market, with the “Architect AI” round at 1.1 billion rubles making up almost a quarter of the half-year volume. No foreign deals were recorded — the market has completely become internal, with capital directed to mature B2B companies with clear revenue.

What This Means for Venture Investors

1. Infrastructure Layer is More Expensive than Model Layer. Temporal, EUCLYD, and DeepKernel show that the premium goes to those who control execution, computation, and data.
2. “Physical AI” Requires Proof. SF Express's order for Yincheng and clinical phases for Nutshell are valued higher than demonstrations.
3. Sovereignty Becomes a Budget Item. European rounds for Open Cosmos and EUCLYD have been raised with a focus on regional capital.
4. Expensive Debt Alters Round Structures. It is worth revisiting floating credit lines and factoring in higher rates into models until the year-end.
5. IPO Window Open for Quality. Anthropic's prospectus will become a benchmark for valuations of private AI companies.

Day’s Summary

The venture market as of September 17, 2026, appears simultaneously generous and demanding: record rounds and new unicorns coexist with tightened criteria and rising capital costs. Investors are paying for scarce assets — efficient chips, real operational data, deeply integrated workflows, and secure infrastructure. Intelligence is becoming cheaper, while systems that convert it into reliable economic outcomes are getting more expensive. This is where capital is headed.
