Liberty Global Tech Ventures Invests in AI Inference Hardware and Software Company, Positron AI
Liberty Global Tech Ventures adds Positron AI to its growing AI portfolio through a major funding round valuing the startup at $5 billion.
Rhea-AI Summary
Liberty Global (LBTYA), via Liberty Global Tech Ventures, has invested in Positron AI as part of an oversubscribed $875 million funding round that values Positron at $5 billion.
The round was co-led by NEA, Valor Equity Partners, Atreides Management, Andra Capital, Dylan Patel’s SemiAnalysis Capital and Jim Clark. Founded in 2023, Positron develops memory-first AI inference hardware and software using LPDDR5X memory to relieve AI inference memory bottlenecks and avoid constrained HBM and CoWoS supply chains. Existing Atlas systems fit standard data centers, and customers include Oracle, Jump Trading and Parasail. Its next-generation Asimov silicon is planned to tape out in late 2026, with production in the second half of 2027, powering Titan, a multi-terabyte-memory inference system.

News Explained
Liberty Global’s announced Positron investment has no disclosed amount or ownership terms, leaving its capital exposure and holder impact unquantified.
Liberty Global Tech Ventures announced an investment in Positron AI, but the release does not state that it has closed; it therefore establishes an announced transaction, not a completed investment or a measurable change in Liberty Global’s ownership structure.
The release omits Liberty Global’s investment amount, resulting ownership stake, use of proceeds, and any conversion terms, so the capital exposure and potential effect on existing common holders cannot be sized from this disclosure.

PALO ALTO, Calif., Sept. 11, 2026 (GLOBE NEWSWIRE) -- Liberty Global Tech Ventures, the technology investment arm of Liberty Global, today announced an investment in Positron AI, a leader in hardware and software for memory-first AI inference systems.
Liberty Global joins a select group of investors in the oversubscribed
Founded in 2023, Positron develops hardware and software designed specifically for AI inference, the stage at which trained AI models process and generate outputs. Its memory-first architecture is designed to lower total cost of ownership and process requests faster by addressing the memory bottlenecks that constrain AI inference.
Positron’s memory-first inference systems use LPDDR5X memory, avoiding constrained HBM and CoWoS supply chains, while achieving more than
Bobbie Maltiel, Partner at Liberty Global Tech Ventures, said: “While AI is being adopted by consumers and enterprises at a phenomenal rate, the ability to deliver token usage at the lowest possible cost is key to the full benefits being delivered for society. The Positron team have a relentless focus on this and we are delighted to be joining them on their mission to deliver high-speed AI at the lowest possible cost to businesses and consumers.”
The market for inference compute, the computing power needed to run AI models rather than train them, is expected to be worth
Its next-generation custom silicon, Asimov, tapes out in late 2026 with production in the second half of 2027. Asimov powers Titan, a multi-terabyte-memory inference system for long-context and next-generation AI workloads.
Liberty Global Tech Ventures invests in category-defining AI and technology businesses and Positron joins firms like ElevenLabs, XBOW, Legora and Higgsfield in selecting Liberty Global as a strategic investor.

ABOUT POSITRON AI
Positron AI builds hardware and software to make AI inference dramatically cheaper and more energy efficient. The company’s shipping product, Atlas, is deployed at hyperscaler scale today, and its next-generation custom silicon, Asimov, tapes out in late 2026 with production in the second half of 2027. Asimov powers Titan, a multi-terabyte-memory inference system for long-context and next-generation AI workloads. Positron’s energy-efficient architecture allows its systems to be deployed in air-cooled or liquid-cooled data centers at varying rack densities, without dependence on constrained HBM or CoWoS supply chains.
