AI chip startups draw record funding amid Nvidia lead
Startups building AI inference chips attracted record investor interest in 2026 as companies seek alternatives to Nvidia’s GPU-dominated stack. Dealroom estimates AI chip startups raised $8.3 billion globally in 2026 so far. Investors argue GPUs were not purpose-built for inference and that new architectures can cut energy and cost at scale. Large rounds cited include Cerebras Systems ($1 billion) and multiple $500 million rounds for MatX, Ayar Labs and Etched; European raises include Axelera and Olix (each north of $200 million). Nvidia continues to invest and consolidate its position — buying Groq assets, backing photonics firms and spending heavily on R&D — while major AI users and foundries report expansion and strong demand for AI compute.
Large capital flows into AI chip startups and major strategic moves by Nvidia (acquisitions, photonics investments, heavy R&D) could reshape AI inference infrastructure, increase competition to Nvidia’s GPU dominance, affect cloud compute economics and influence enterprise deployment choices.

European AI chip startups seek nine‑figure funding
European startups building alternatives to Nvidia GPUs for AI inference are pursuing large funding rounds as demand for efficient inference grows. Dutch Euclyd, founded in 2024 and backed by former ASML executives, is in talks for at least a €100 million round, founder Bernardo Kastrup told CNBC. Other European firms — including the U.K.’s Optalysys, Fractile and France’s Arago — are reportedly targeting nine‑figure raises, while investors have put over $200 million into Netherlands’ Axelera and the U.K.’s Olix so far in 2026. Startups claim novel architectures (e.g., photonic processors, multi‑chiplet systems, in‑memory or distributed processing) can deliver substantially higher power efficiency for inference versus current GPU generations. Challenges cited include long chip development cycles, fragmented European foundry and procurement ecosystems, and funding gaps versus U.S. competitors. Nvidia continues heavy investment in R&D and recent acquisitions and investments to support inference and photonics work.
Nvidia's AI Investments Reach $99 Billion, Becoming Major Backer
Nvidia has become one of the world's largest corporate backers of AI companies, with its equity investments soaring to $99 billion as of July 26, up from $7 billion a year earlier. The chip giant committed over $40 billion in 2026 alone, financing rounds across the AI stack including frontier labs, neoclouds, and photonics startups. Recent deals include a $30 billion investment in OpenAI, a $2 billion investment in CoreWeave, and a $2 billion investment in Nebius. Nvidia also announced plans to acquire Hugging Face for $12.9 billion. The company uses these investments to enhance its ecosystem, secure supply chains, and protect its CUDA moat, with 106% revenue growth to $96.2 billion in its fiscal second quarter.
AI CapEx Shift Boosts Nvidia's GPU Edge
A CNBC analysis argues that capital spending for AI will shift from long‑lived data‑center infrastructure toward shorter‑lived chips, benefiting Nvidia as the leading GPU vendor. JPMorgan strategist Tarek Hamid predicts chip financing growth through 2030 and forecasts more than $3 trillion in financing for AI chips and essential hardware over the next five years, with silicon spending rising to about $800 billion in roughly four years. Nvidia reported $81.6 billion in revenue for its fiscal first quarter (up 85% year‑over‑year) and executives including CEO Jensen Huang and CFO Colette Kress emphasize the company’s central role in AI. JPMorgan expects Nvidia to ship 8.9 million GPUs this year versus millions of competing TPUs and Amazon chips, and highlights partnerships with OpenAI, Anthropic, Amazon and Microsoft as supportive factors for Nvidia’s position.
