MatX Secures $500M Series B to Challenge Nvidia’s AI Dominance
In a significant move poised to shake up the artificial intelligence hardware landscape, MatX, an innovative AI chip startup, has successfully closed a substantial $500 million Series B funding round. This latest capital injection propels the company forward in its ambitious quest to develop processors that are ten times more efficient at training large language models (LLMs) and delivering results than Nvidia’s industry-leading GPUs.
A Powerful Investment Coalition
The Series B round saw leadership from prominent investors Jane Street and Situational Awareness, an investment fund spearheaded by Leopold Aschenbrenner, a former researcher at OpenAI. The impressive roster of participants also includes industry giants like Marvell Technology, NFDG, and Spark Capital, alongside high-profile individual investors such as Stripe co-founders Patrick Collison and John Collison. Reiner Pope, MatX’s founder and CEO, announced the successful close via a LinkedIn post, underscoring the strong confidence investors place in the startup’s vision.
While MatX has not publicly disclosed its latest valuation, the competitive landscape offers a glimpse into the potential scale. Bloomberg recently reported that Etched, a close rival in the AI chip sector, secured a $500 million round at a staggering $5 billion valuation last month.
From Google’s TPUs to MatX’s Vision
This latest funding milestone follows MatX’s Series A round of approximately $100 million, led by Spark Capital, which valued the startup at over $300 million in 2024. The company’s formidable foundation is built upon the expertise of its co-founders, Reiner Pope and Mike Gunter, both alumni of Google’s elite hardware division.
Before co-founding MatX in 2023, Reiner Pope was instrumental in leading AI software development for Google’s Tensor Processing Units (TPUs), the tech giant’s proprietary AI chips. Mike Gunter, his co-founder, played a pivotal role as a lead designer of the TPU hardware. Their combined experience positions MatX with a deep understanding of the intricacies and challenges of developing cutting-edge AI processing units.
Paving the Way for Future AI Innovation
The newly acquired capital is earmarked for critical next steps: enabling MatX to commence production of its advanced chips with TSMC, the world’s largest independent semiconductor foundry. The company anticipates beginning shipments of its revolutionary processors in 2027, a timeline that signals a determined push to bring its high-performance solutions to market and directly challenge Nvidia’s established dominance in the rapidly expanding AI hardware sector.
