Positron AI announced on September 10 that it raised $875 million in a Series C financing at a $5 billion post-money valuation, providing capital for its next-generation AI inference hardware. Qatar Investment Authority confirmed that it participated in the round, saying the funding will support development of Positron’s Asimov silicon and commercialization of its Titan systems.
The financing puts a sharply higher price on the AI-chip startup only months after its prior raise. The proceeds are earmarked for chip design and manufacturing work, engineering data-center capacity, and expanding production of its hardware systems.
Series C structure and $5 billion valuation
The financing is structured as a $375 million Series C at a $3.5 billion pre-money valuation and a Series C-1 tranche of up to $500 million, according to Positron.
The disclosed headline amount is $875 million, including as much as $500 million from the contingent C-1 tranche. The announcement associates the $5 billion post-money valuation with the Series C and provides no additional C-1 financial terms beyond its potential size.
Reuters reported via Investing.com that Positron’s valuation was about $1.06 billion after a $230 million funding round in February 2026. It is now $5 billion, an increase of nearly five times in a matter of months.
Funding Asimov tapeout, data-center capacity and Titan production
Positron said the proceeds will fund tapeout of Asimov silicon, a more than 2-megawatt engineering data center, and a scale-up in Titan production. Tapeout is a critical step in moving a chip design toward manufacturing, making the stated uses of capital directly tied to bringing the company’s inference silicon and systems to market.
QIA’s confirmation focused on the same execution priorities. In its statement on the investment, the sovereign wealth fund said its participation would support Asimov’s development and Titan’s commercialization.
That allocation places the new financing across the chip-development, testing-infrastructure and system-production stages. Positron’s September 10 announcement did not provide a timetable for the Asimov tapeout, completion of the engineering data center, or Titan production ramp.
