Positron AI가 Asimov 실리콘 테이프아웃과 Titan 시스템 양산을 포함한 메모리 우선 추론 시스템 확장을 위해 $875M Series C 펀딩 라운드를 완료했다.

Positron AI announced an $875 million Series C financing at a $5 billion post-money valuation, with the round co-led by NEA, Atreides Management, Valor Equity Partners, Andra Capital, Dylan Patel's SemiAnalysis Capital, and Jim Clark, founder of Silicon Graphics and Netscape. Forest Baskett of NEA, Gavin Baker of Atreides Management, Thomas Jermoluk from Jim Clark Office, and Dylan Patel will join Positron's board of directors.

The funding reflects a fundamental market shift: as AI's center of gravity moves from training to inference, the bottlenecks are no longer compute but memory capacity, memory bandwidth, and power. Positron builds memory-first inference systems optimized for these constraints. Its architecture achieves more than 90 percent of available memory bandwidth, uses commodity LPDDR5X memory to sidestep the constrained supply chains around HBM and CoWoS, and delivers leading efficiency metrics in tokens per dollar and tokens per watt. The energy-efficient design allows deployment across air-cooled or liquid-cooled data centers at varying rack densities.

"Speed matters in this market, both in how quickly we ship new generations of silicon and in how quickly they reach customers. Deploying Atlas at scale taught us an enormous amount about what inference customers actually need, and we have carried those lessons directly into Asimov and Titan," said Mitesh Agrawal, CEO of Positron AI. "Our focus now is to tape out Asimov, bring Titan to production, and scale manufacturing to meet the demand in front of us."

Positron is currently deploying more than 50 racks of Atlas, its first-generation inference system, at Oracle Cloud Infrastructure, where key partner Parasail leverages the capacity for its own inference service. Additional Atlas production customers include Jump Trading and i3d.net.

The financing was structured in two tranches: a $375 million Series C at a $3.5 billion pre-money valuation, co-led by NEA, Andra Capital, Atreides Management, Valor Equity Partners, and SemiAnalysis Capital; and a Series C-1 of up to $500 million led by NEA and Jim Clark. Other investors include DFJ Growth, Qatar Investment Authority, Resilience Reserve, Arena Private Wealth, Natural Capital, Helena, 1517 Fund, Flume Ventures, Unless, Boardman Bay Capital Management, Fincadia Advisors, Banyan Ventures, and U First Capital, alongside strategic investors VentureTech Alliance, Hudson River Trading, Cisco Investments, and Naver Ventures.

The capital will fully fund the tapeout of Asimov, Positron's next-generation silicon; construction of a 2 MW+ engineering data center and emulation platform; and the production ramp of Titan, including LPDDR5X supply commitments, production capacity, system integration, and go-to-market expansion. Asimov tapes out on TSMC N3P at the end of 2026, with production ramping in the second half of 2027. Each Asimov chip carries 288 GB to 2,304 GB of memory. Titan combines four to eight Asimov chips into a single system, engineered to serve models exceeding 16 trillion parameters with context windows beyond 10 million tokens in a single node, and scales to thousands of nodes.

"The Positron inference architecture balances compute with the enormous required memory bandwidth and extraordinarily large context and weight storage," Jim Clark said. "Its optimized power consumption, cost, and density is near ideal for the inference requirements of the next evolution of frontier large language models with trillions of parameters."
