Positron Raises $230M to Rival Nvidia AI Chips

RENO, Nev. – Semiconductor startup Positron has landed $230 million in Series B funding, aiming to accelerate the rollout of its high-speed memory chips-a crucial element for powering the next wave of artificial intelligence applications.

Demand Surges for AI Alternatives to Nvidia

The investment underscores a growing push to diversify the AI chip market, as companies seek alternatives to industry leader Nvidia.

• Positron’s Series B round was led by Qatar Investment Authority (QIA), reflecting a broader investment in AI infrastructure.
• The funding will be used to scale production of Positron’s memory chips, designed for AI workloads.
• OpenAI is reportedly exploring alternatives to Nvidia’s chips, creating an chance for companies like Positron.
• Qatar is positioning itself as a hub for AI services in the Middle East, with a $20 billion AI infrastructure joint venture.
• Positron’s total funding now exceeds $300 million, signaling strong investor confidence.

The Reno-based company’s latest funding round comes as hyperscalers and AI firms increasingly look to reduce their dependence on Nvidia. OpenAI, a major Nvidia customer, has reportedly been dissatisfied with some of Nvidia’s newest AI chips and has been actively seeking alternatives as last year, according to sources.

Did you know? – AI “inference” is the process of using a trained model to make predictions. It generally requires less computing power than “training” a model from scratch.

What makes Positron different? The company claims its first-generation chip, Atlas, manufactured in Arizona, can deliver performance comparable to Nvidia’s H100 GPUs while consuming less than a third of the power. Positron is strategically focused on “inference”-the computational process of running AI models for real-world applications-rather than the resource-intensive task of training those models. This positioning aligns with a growing demand for hardware optimized for deploying AI at scale.

Qatar’s bold Bet on AI Infrastructure

The investment from Qatar Investment Authority (QIA), the country’s sovereign wealth fund, highlights a significant push into “sovereign” AI infrastructure. This initiative was prominently discussed at Web Summit Qatar in Doha this week, where officials emphasized the importance of compute capacity for global economic competitiveness. Qatar aims to establish itself as a leading AI services hub in the Middle East, and investments in startups like Positron are central to that strategy.

Pro tip – Sovereign AI refers to a nation’s control over its AI infrastructure, including data, algorithms and computing power, to ensure data security and strategic independence.

This strategy is already materializing through considerable commitments, including a $20 billion AI infrastructure joint venture with Brookfield Asset Management, announced in September.

Positron’s fundraise brings the three-year-old startup’s total capital raised to just over $300 million. The company previously secured $75 million in funding last year from investors including Valor Equity Partners, Atreides management, DFJ Growth, Flume Ventures and Resilience Reserve.

Beyond its memory capabilities, sources indicate Positron’s chips also demonstrate strong performance in high-frequency and video-processing applications.
