Nvidia still runs roughly four of every five AI chips sold today. In December 2025, Nvidia paid $20 billion to license rival Groq's chip design and hire its founding team. It then built its own inference-only rack from that technology, launched at Nvidia's GTC conference in March 2026.
Cerebras went public on Nasdaq in May 2026, raising $5.55 billion. Etched's valuation jumped to $21 billion in under a month, and it shipped its first chip to Jane Street on August 18. AMD is now backing both sides, putting up to $5 billion into Anthropic and striking an inference deal with Cerebras.
Why it matters
If Nvidia can absorb its biggest inference-chip rival for $20 billion without a formal merger review, it can buy its way out of competition.

Fictional AI pastiche — not real quote.
"Nine-figure fortunes staked on the certainty that the king of a hill will presently be displaced — this is not investment but rather the ancient ritual of ambitious men paying to watch other ambitious men fail. That four in five chips bear one maker's mark is called a monopoly by the envious and an ecosystem by the beneficiary; that investors now wager two hundred millions on the word "inference" suggests they have mastered the vocabulary of the future without troubling themselves to understand it."

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
1995-2002
The 1990s graphics chip wars
Through the late 1990s, a crowded field of graphics chip makers, including 3dfx, ATI, Matrox, S3, Trident and a young Nvidia, fought to define the PC 3D graphics market. Each company pitched a different architecture and a different bet on what gamers and developers would adopt.
Then
Pricing collapsed, marginal players failed, and the market consolidated faster than investors expected. 3dfx, the early leader, went bankrupt by 2002.
Now
Two winners, Nvidia and ATI (later AMD), emerged with durable share. The lesson: in chip categories with high R&D costs and software lock-in, late-cycle consolidation is brutal and most well-funded entrants do not survive.
Why this matters now
Today's inference chip field looks structurally similar: many funded entrants, competing architectures, no clear winner, and a software moat held by the incumbent. The 1990s suggest the next five years will end with two or three survivors, not ten.

May 2016
Google launches the TPU (2016)
At Google I/O, Google revealed it had been running a custom AI chip called the Tensor Processing Unit in its data centers since 2015. It was the first time a major operator publicly claimed that purpose-built silicon could beat Nvidia GPUs on AI workloads at scale.
Then
The TPU opened a credible alternative path for AI compute and validated the thesis that workload-specific chips could compete with general-purpose GPUs.
Now
TPUs became central to Google's AI infrastructure and inspired a generation of custom-silicon efforts at Amazon (Trainium, Inferentia), Microsoft (Maia) and Meta (MTIA). It also made the inference chip startup category investable.
Why this matters now
Every Fractile, Groq and Etched pitch deck traces back to the TPU's central claim: GPUs are not the right shape for AI, and a purpose-built chip can win. The 2026 funding race is the venture-backed extension of that 2016 idea.

November 2019
Amazon launches AWS Inferentia (2019)
Amazon unveiled Inferentia, a custom inference chip built in-house for AWS, and later added Trainium for training. The chips were aimed at lowering Amazon's own compute costs and offering customers a cheaper alternative to Nvidia inside AWS.
Then
Inferentia gained limited adoption initially as customers stuck with familiar GPU tooling.
Now
By the mid-2020s, Trainium and Inferentia were central to AWS's AI pitch and underpinned the deeper Amazon-Anthropic partnership announced in 2024. Custom hyperscaler silicon proved viable at scale.
Why this matters now
Hyperscalers can and do build their own inference chips. That sets a ceiling on how much of the inference market the independent startups can address: the biggest buyers may bring the workload in-house rather than buy from Fractile or Groq.
