Current News on Startups and Venture Capital Investments as of 12 September 2026: Mega-Rounds in Infrastructure, AI Chips, and Defence Technologies, IPO Preparations for DeepSeek and Oura, Strategic Deals by Meta and Salesforce, as well as Signals for Investors and Funds.

As we enter the second week of September 2026, the direction of venture capital has become increasingly apparent. Just in one day, the ten largest deals brought in approximately $4.8 billion, with 93% of this amount going to just three companies — The Boring Company, Positron AI, and Mach Industries. The market has refrained from becoming "broadly risky": investors are willing to write substantial cheques only for those startups that control scarce resources — tunnels, inference chips, optical connections for data centres, or defence production.

Key events shaping the venture capital agenda for Saturday, 12 September 2026:

• The Boring Company completed a $3 billion Series D round at a valuation of $23 billion, with the UAE as the lead investor and the deal coupled with a contract for the construction of over 150 km of tunnels.
• Positron AI raised $875 million at a $5 billion valuation just seven months after a round at $1.06 billion.
• Mach Industries expanded its Series C by an additional $600 million; the valuation of the defence startup doubled to $3.7 billion within three months.
• Harvey attracted $550 million at a valuation of $15.5 billion, reinforcing the notion of vertical AI as an independent category.
• DeepSeek has hired CITIC Securities to prepare for an IPO on Shanghai's STAR Market at a potential valuation of around $75 billion.
• Meta and Salesforce are acquiring AI teams: Stilla.ai is already within Meta's orbit, while Listen Labs is under discussion for approximately $2 billion.

The Boring Company: $3 Billion and Sovereign Capital as a Market Entry Strategy

The largest deal of the week is The Boring Company's $3 billion Series D round at a $23 billion valuation. The lead investor is the United Arab Emirates, with co-investors including Sequoia Capital, Andreessen Horowitz, and Baron Capital. Importantly, the financing comes packaged with an agreement for the construction of over 150 km of tunnels in the UAE.

For venture investors, this exemplifies a new format: sovereign capital acts as both a shareholder and a key customer, thus alleviating the company’s risk of customer acquisition. However, the engineering and project risks remain unchanged – the company’s primary showcase continues to be the Vegas Loop, while projects in Los Angeles, Washington, and Chicago have been halted. Nonetheless, the $23 billion valuation establishes a new norm: infrastructure startups with technology, political access, and the ability to participate in tenders for projects of several kilometres in scale are receiving venture multipliers.

AI Infrastructure: Inference and Photonics Instead of Another Chatbot

The focus of venture investment in artificial intelligence has definitively shifted from models to the "hardware" that supports them.

Positron AI: $875 Million as an Alternative to Nvidia in Inference

The Reno, Nevada-based startup closed a $375 million Series C and a Series C-1 of up to $500 million at a $5 billion valuation. The round was led by NEA, Atreides Management, Valor Equity Partners, Andra Capital, SemiAnalysis Capital, and Jim Clark; the deal involved participation from Qatar Investment Authority, Cisco Investments, and Naver Ventures. The Asimov processor employs a "memory-first" architecture with a capacity of up to 2.3 TB per chip, with mass production slated for the second half of 2027. Over 50 previous generation racks have already been deployed in Oracle Cloud Infrastructure.

Ayar Labs: Optical Connections Valued at $5 Billion

The silicon photonics developer added $150 million to its March Series E, bringing the round total to $650 million and the valuation to approximately $5 billion, up from $3.8 billion at the beginning of the year. Strategic investors include Nvidia, AMD, and MediaTek. Demand from public companies substantiates the thesis: Oracle reported quarterly capital expenditures of $28.5 billion, while hyperscalers issued approximately $220 billion in bonds over the year to finance data centres.

Defence Technologies: Mach Industries Doubles Valuation in a Quarter

Mach Industries secured an additional $600 million in its Series C expansion, bringing the total round amount to approximately $900 million. The valuation rose from $1.8 billion in June to $3.7 billion. The deal included participation from Ribbit Capital, Infinite Capital, Bedrock Capital, and Sequoia. The company manufactures vertical take-off drones, long-range strike systems, and counter-drone measures, while also expanding into propulsion systems through its acquisition of Exquadrum.

Investors are financing not a standalone platform, but an industrial base: vertical integration in production is becoming a critical barrier to market entry. In 2026, the defence sector has definitively ceased to be a niche venture category — over the first half of the year, Anduril raised $5 billion while Finland's ICEYE secured $1.2 billion.

Applied AI: Premium for Owning the Workflow

Alongside the mega-rounds in infrastructure, financing for vertical AI companies continues, with their protection based not on models, but on integration into regulated processes:

1. Harvey — $550 million at a valuation of $15.5 billion (led by Diffusion and Lightspeed); the legal AI startup released its own model, Tenet, based on open weights.
2. Inspiren — $70 million Series C at a valuation of $550 million led by NewView Capital; AI monitoring in nursing homes.
3. Rogo Technologies — around $30 million in strategic investments from Citi, Barclays, BNP Paribas, MUFG, and Société Générale; banks are simultaneously becoming shareholders and clients.
4. Graph AI — $13.3 million from Insight Partners and Bessemer for pharmacovigilance automation.

The common denominator of these deals is a specific buyer, measurable operational results, and a high cost of replacing the product in the client’s stack.

M&A and Strategic Deals: Corporations Acquire Teams, Regulators Observe

Meta acquired the Stockholm-based startup Stilla.ai, which emerged from stealth mode after a $5 million seed round, to enhance business agents in WhatsApp and Messenger. Salesforce is negotiating to purchase Listen Labs for approximately $2 billion — even though the startup had recently signed a term sheet at $125 million for a $1.5 billion valuation. This illustrates how AI companies are becoming acquisition targets long before reaching traditional scale.

Simultaneously, the US Department of Justice is investigating Nvidia’s licensing deal with Groq valued at $17–20 billion regarding potential antitrust violations. For investors in chip startups, this serves as an important signal: the "license plus team transition" model as an alternative to a notified merger may no longer be viable.

Asia: DeepSeek Prepares for IPO, Alibaba Values UniPat AI at $2.5 Billion

DeepSeek has engaged CITIC Securities and three other underwriters to prepare for a listing on the STAR Market of the Shanghai Stock Exchange; the process is expected to commence by the end of the year. Concurrently, the company is conducting a pre-IPO round at a valuation of around 500 billion yuan (approximately $75 billion) following a June round of $7.4 billion. Alibaba leads a $300 million round in UniPat AI — a model evaluation and training platform — at a valuation of $2.5 billion, with participation from Tencent and HSG. China is placing billion-dollar valuations on "tools" of AI, rather than solely on the models themselves. In India, Swish secured $24 million in Series B from Bertelsmann India Investments for ten-minute food delivery.

IPO Market: The Window is Open, but Selectively

Oura has filed for a Nasdaq listing under the ticker OURA and aims to raise up to $3 billion at a valuation exceeding $16 billion; the offering is anticipated by the end of September. Conversely, Motive Technologies has withdrawn its IPO of approximately $600 million — the public market still separates issuers into "AI giants" and all other companies. Anthropic, as of mid-week, is pushing its offering to October. Direct listings are experiencing a record year in volume but not in returns for investors.

Russia and CIS: The Funnel has Narrowed

As of 9 September, approximately 90% of Russian startups were found to be unprepared for investments: out of 2,681 applications for one of the industry shows, only 2-4 projects made it to the final selection, while investors made offers exceeding 700 million rubles. The selection process is becoming stricter — the market is progressively filtering out projects without confirmed economics. The global context is amplifying this trend: according to KPMG, the global volume of venture investments for the first half of 2026 reached $560.4 billion, but the top 10 deals accounted for nearly half of this total, with OpenAI and Anthropic alone receiving about $217 billion.

What This Means for Venture Investors and Funds

The September landscape aligns with the formula of "capital in abundance, scarcity remains." Practical takeaways for managers include:

• Strategic capital is becoming a distribution channel. UAE for Boring, banks for Rogo, Oracle for Positron — an investor who is also a customer effectively lowers commercial risk more than a higher valuation from a financial fund.
• Capital intensity is no longer a drawback if it buys down the barrier. Factories, chips, and photonics are being financed in tranches tied to specific milestones: design, delivery of functional products, qualification by the customer.
• "AI-powered" is not an investment thesis. The premium goes to those who own the regulated process, data, and switching costs.
• Barbell market requires two strategies. Mega-cheques are concentrated in the US, while seed and early rounds in Europe, India, and China remain small and rigorously curated.

The venture market enters autumn 2026 with record capital reserves and a shrinking circle of recipients. Companies that cannot be easily replicated with the next model release will emerge as the winners.
