AI chip startups design processors built to train and run AI models, and they compete for a market led by Nvidia. Investors put about $10.7 billion into semiconductor startups through early June 2026, according to Crunchbase, putting the year on track to pass 2025.
The sector also produced its first large public listing. Cerebras Systems raised $5.55 billion in its May 2026 Nasdaq IPO, and Nvidia paid $20 billion to license Groq’s technology at the end of 2025.

AI chip startup funding in 2026
Crunchbase counted about $10.7 billion invested in semiconductor startups from seed to pre-IPO rounds through June 10, 2026. Cerebras, MatX, Ayar Labs and Etched each raised $500 million or more in the first quarter.
Q2 2026 added more than $6 billion across 80 chip startups, Semiconductor Engineering reported. Eighteen of those companies raised $100 million or more.
Large rounds continued in the second half. Tenstorrent raised a $1.5 billion Series E on October 19, 2026, at a $6.2 billion valuation, about double the $2.6 billion mark from its late-2024 round.
That round led one of the busiest weeks of the quarter, as shown in this weekly AI funding roundup for October 18 to 25, 2026.
Cerebras Systems: the first AI chip startup IPO of 2026
Cerebras priced its IPO at $185 per share on May 13, 2026, $25 above the top of its marketing range. It sold 30 million shares under the ticker CBRS and raised $5.55 billion.
The pricing valued Cerebras at $39.82 billion. The company recorded $510 million in revenue and $237.8 million in net income for 2025, according to its filing.
Cerebras had first filed for an IPO in September 2024 but withdrew after a US national security review of its investor G42. Its shareholder history is covered in this look at who owns Cerebras.
Nvidia’s role among AI chip startups
Nvidia is both the main competitor and an investor. On December 24, 2025, it agreed to pay $20 billion to license Groq’s inference technology and hire most of its staff, including co-founder and CEO Jonathan Ross.
Nvidia also backs startups in the chip supply chain. It invested in Ayar Labs’ $500 million Series E, SiFive’s $400 million Series G and Upscale AI’s $190 million round in 2026.
The full list of the company’s bets appears in this summary of Nvidia’s startup investments in 2026.
Types of AI chip startups
| Category | What the chips do | Example companies |
|---|---|---|
| Wafer-scale processors | Use a full silicon wafer as one chip for training and inference | Cerebras Systems |
| Inference accelerators | Run trained models at lower cost per query | Groq, Positron AI, Fractile, D-Matrix |
| Model-specific chips | Hard-wire transformer or language-model operations | Etched, MatX |
| Open-architecture processors | Build AI chips on the RISC-V instruction set | Tenstorrent, SiFive |
| Interconnect and networking | Move data between chips with optics or custom networks | Ayar Labs, Upscale AI |
Inference has the most companies in this table. D-Matrix, backed by Microsoft, raised $275 million at a $2 billion valuation in late 2025 for chips that run trained models.
What investors look for in AI chip startups
Round sizes in this sector are large. Seven private AI chip startups raised $500 million or more in a single round during 2026, counting the deals covered in this article.
Investors also watch for customer contracts and a public-market path. Cerebras’s profit before its IPO gave other chip companies a reference point, and others in the queue appear in this tracker of upcoming AI IPOs.
Conclusion: the state of AI chip startups in 2026
AI chip startups raised more than $10 billion in the first half of 2026, led by Cerebras, Etched, MatX and Ayar Labs. Tenstorrent’s $1.5 billion round in October showed that large checks continued into the second half.
The Cerebras IPO and Nvidia’s $20 billion Groq deal gave investors two exit routes: a public listing or a licensing agreement with an incumbent. Inference chips, which run trained models, accounted for several of the year’s largest rounds, including those of Positron AI and Etched.
