September added serious weight to the unicorn economy. A total of 38 companies joined The Crunchbase Unicorn Board, bringing $71 billion in new value with them — because apparently private-market gravity took the month off.
Semiconductors, financial services, and space technology led the new arrivals by count. The rest came from biotech, AI infrastructure, AI training, security, and frontier labs, showing that the latest funding rush is not confined to one fashionable corner of technology.
Twenty-one of September’s new unicorns are headquartered in the United States. China added six, the U.K. added three, and Canada, Saudi Arabia, Japan, Israel, Italy, Finland, Germany, and Bulgaria each added one.
Chip companies set the pace
The semiconductor group included Fab2, Celero Communications, Micronano Core, Evas Intelligence, and SiMa.ai. Fab2, an Austin-based semiconductor manufacturing startup, closed a $500 million Series A at a $3.7 billion valuation, giving the month one of its largest new entrants.
Celero Communications, based in Irvine, California, raised $275 million in a Series C, lifting its valuation above $3 billion and bringing total funding to $415 million. Atreides Management, Valor Equity Partners, and CapitalG led the round — a familiar cast for a deal aimed at putting more money behind semiconductor infrastructure.
Micronano Core, an AI chip developer based in Hangzhou, announced a $149 million Series C and reached a $1 billion valuation. Evas Intelligence, a Beijing-based AI chip company, raised $298 million at a $2.2 billion valuation.
SiMa.ai, based in San Jose, California, develops specialized AI chips and software. Its $150 million Series C valued the company at $1.45 billion, adding another U.S. chip startup to a board increasingly shaped by the hardware needed to run AI systems.
Valuations are climbing beyond the new arrivals
The September activity also pushed several existing board members to much higher valuations through new funding rounds. Cognition, a San Francisco-based developer of AI for software engineering, climbed to $48 billion from $26 billion only four months earlier.
Crusoe, a data center provider, reached a $31 billion valuation last month, up from $10 billion a year ago. Mistral, a Paris-based frontier lab, reached $24.4 billion in its more recent funding round, compared with $13.7 billion a year ago.
Those jumps help explain why September added $71 billion even though the headline count was 38 companies. New unicorns matter, but fresh capital can also reprice companies already on the board — sometimes by billions before the coffee gets cold.
Through September 2026, 311 companies have joined The Crunchbase Unicorn Board this year. That puts 2026 on track to become the second-highest year for new unicorn creation, behind 2021, when the count topped 600.
The funding picture also extends beyond the September board additions. In October 2026, Overmatch Ventures announced the first annual Austin Deep Tech 50, placing Austin’s deep-tech ecosystem alongside the broader surge in chips, AI infrastructure, defense technology, robotics, and power systems.
Aabid Razvi, Principal at Overmatch Ventures, said: “The companies rebuilding and reinventing America’s power grid, defense industrial base, and robotics — the technologies that decide whether America leads the next decade — are doing it in Austin.”
That Austin announcement adds a regional marker to a national funding story. Fab2’s $3.7 billion valuation, the growth of AI chip companies such as Micronano Core and Evas Intelligence, and the rise of data center provider Crusoe all point toward the same capital priorities: compute, infrastructure, and the hardware beneath the software.
For venture investors, 2026 is shaping up as a year of scale rather than a repeat of the 2021 peak. The market has not returned to more than 600 new unicorns, but 311 companies had already joined by September — and September alone supplied enough money and valuation growth to make the comparison unavoidable.
