Funding Rounds

Funding rounds are the staged financings, from seed to pre-IPO, in which private companies sell equity or convertible notes to investors for capital. The valuations set in a year's rounds show which businesses investors will pay most for and how fast those prices move. In 2026 the answer was artificial intelligence: one AI developer took close to a third of a quarter's global venture funding, and rounds of $1 billion or more became routine.

The money concentrated in AI model makers and in the infrastructure beneath them, including compute, databases and security for AI agents. Valuations reset within months, in some cases more than tripling between consecutive rounds. Some prices were backed by annualised or recurring revenue of $200 million or more; others rested on expectations, with no named customer or with large losses disclosed. Hedge funds, sovereign funds, banks, corporations and credit firms led several of the rounds, sometimes through convertible notes or alongside debt.

As of October 2026, Modal showed AI infrastructure still repricing sharply: it closed a $750 million Series D at a $15.75 billion valuation, more than three times its price five months earlier.

Concentration in AI

Venture capital in 2026 flowed to a small number of AI companies in very large amounts. Anthropic raised roughly $65 billion in the second quarter of 2026, close to a third of all global venture funding that quarter, and the round lifted it past OpenAI to the top of Crunchbase's Unicorn Board, a climb helped by SpaceX's exit to the public markets. Billion-dollar rounds were routine in the same quarter: 16 companies closed one, together about $108.6 billion or 53% of second-quarter funding.

Infrastructure for AI agents

Late-stage investors also paid up for the layers that let AI models and agents, software that carries out tasks on its own, run in production. Modal, which rents GPU capacity and runs code for AI developers, raised its $750 million Series D in October 2026 as annualised revenue passed $1 billion. Supabase raised $150 million four months after a $500 million Series F and agreed to acquire Turso, a startup building a SQLite-based database for agents that create and discard data stores on the fly. Supabase said in October 2026 that agents created 70% of the new databases on its platform.

Securing those agents drew two $400 million rounds within days of each other in September 2026. Cyera took a $400 million extension of its Series G at a valuation above $12 billion, three months after a $600 million Series G at the same price. Island raised a $400 million Series F at $6.4 billion, pitching its platform, which grew from an enterprise browser into data-loss prevention and network security, as a single control plane governing both employees and the AI agents working alongside them.

Valuation step-ups

Valuations reset within months rather than years. Modal's valuation more than tripled from the $4.65 billion it fetched in May 2026. Quantum computing startup Oratomic raised a $475 million Series B at $5.4 billion, three months after a Series A at $1.5 billion. TypeSafe AI raised $870 million at a $7.5 billion valuation less than a month after launching its Jev decision model, having raised only a $40 million seed round before the launch.

Companies with longer records repriced more slowly but still sharply. EliseAI, which automates administrative work for housing and healthcare operators, raised $350 million at $4 billion, nearly double the $2.2 billion set by its Series E 13 months earlier. Island's $6.4 billion was more than double its 2024 valuation. Not every price moved up: home-financing startup Homeward said the undisclosed valuation behind its $120 million Series D was in line with the roughly $800 million mark of its 2021 Series C.

Revenue against expectations

The prices rested on very different evidence. Modal said its business grew more than 15 times year over year. EliseAI said in June 2026 that it had passed $200 million in annual recurring revenue after doubling revenue every year for five years. TypeSafe AI's round rested on adoption rather than disclosed revenue: Andreessen Horowitz said about a quarter of the Fortune 500 integrated Jev in its first week.

Other rounds priced the future. SignSplit's $400 million seed round at a $1 billion valuation backed a platform for licensing consent-verified data to AI buyers. Its chief executive told Forbes Italia the valuation reflected the technology's future market rather than present business, and neither SignSplit nor its backer named a customer. Dealroom's report on Oratomic cited Gartner's projection that more than half of quantum startups would shut down by 2030 for lack of revenue. The IPO filing of London-based AI data-centre operator Nscale sought a valuation of up to $35 billion while disclosing a $1.02 billion net loss for the first half of 2026 and substantial doubt that it could continue as a going concern.

Lead investors and deal structures

Investors from outside the venture industry led several of the year's rounds. Hedge fund Third Point led Nscale's $3.36 billion pre-IPO round, made of convertible notes that turn into equity at its US IPO. Nvidia, Nscale's largest supplier, committed $1 billion of it, drawing scrutiny over circular financing between chipmakers and the operators that buy their GPUs.

Banks, sovereign funds, corporations and credit firms led others. Goldman Sachs Alternatives supplied Cyera's extension, and Singapore's sovereign wealth fund GIC led Supabase's round. W Group, a fintech and technology conglomerate, made the entire commitment behind SignSplit's seed round, a mix of capital and strategic resources whose cash share was not disclosed, and Lockheed Martin led counter-drone maker Fortem Technologies' $50 million Series B. Asset-backed credit firm Saluda Grade led Homeward's round, which came with a separate $330 million debt facility.

Venture firms led most of the other rounds, among them Andreessen Horowitz at TypeSafe AI, Accel at Modal and Evolution Equity Partners at Island.
