Positron AI, a company developing hardware and software for AI inference, announced on Sept. 10, 2026, an $875 million Series C financing and described it as carrying a $5 billion post-money valuation. The announcement establishes that Positron made those claims, but the reviewed evidence does not independently establish that the full amount closed.
The financing structure described by Positron and reported by Reuters comprised a $375 million Series C at a $3.5 billion pre-money valuation and a Series C-1 tranche of up to $500 million. Because the second tranche was described as “up to” $500 million, the evidence does not establish that investors provided the entire announced $875 million. Qatar Investment Authority announced its participation on Sept. 10, while Liberty Global Tech Ventures announced an investment in Positron on Sept. 11; those announcements confirm the investors’ disclosures but do not independently verify the financing’s full amount, terms or closing status.
Positron said the capital would support the tapeout of its Asimov silicon and the production ramp of its Titan inference system. Those are intended uses described by the company, not independently verified outcomes.
