Top developments
Tenstorrent Secures $1.5B at $6.2B Valuation
On October 19, 2026, AI chip startup Tenstorrent announced a $1.5 billion Series E funding round, led by Trace Capital. This round boosts the company's valuation to $6.2 billion, up from $2.6 billion in 2024. The funding follows earlier acquisition interest from Intel and Qualcomm, allowing Tenstorrent to remain independent while scaling its open-weight AI chips.
Cerebras Shares Hit Post-IPO Lows Amid Nvidia Pressure
Cerebras Systems (CBRS) stock has sunk below its $185 IPO price, driven by a broader AI infrastructure selloff and the expiration of early investor lockups. Despite the decline, which has erased over 60% of its value since its May debut, some Wall Street analysts and major banks continue to raise price targets, arguing the market is fundamentally wrong about the company's long-term potential.
Inference Chip Valuations Surge 9x in Two Years
A new PitchBook report reveals that the median valuation of AI chip makers has grown nine times over the past two years, rising from $194 million to $1.7 billion. VC deal value for inference AI startups reached approximately $4.2 billion through August 2026, putting the year on pace to exceed 2025's $5.2 billion total. This surge reflects the intense competition and high stakes in the inference compute space.
Local view
Chinese media outlets, including Sina and ChainCatcher, have closely tracked the Tenstorrent funding round, noting the $1.5 billion raise and $6.2 billion valuation as significant benchmarks for the global AI chip sector. Additionally, reports highlight that Li Auto's chip subsidiary, Shanghai Machin Heart Technology, completed a first-round equity financing of 1.625 billion yuan, reaching a post-money valuation of 17.1 billion yuan. Li Auto contributed 1 billion yuan to this round, retaining a 74.01% stake.
Context & numbers
The global AI accelerator chips market is forecast to grow at a CAGR of 23.5% from 2026 to 2034, driven by generative AI and edge computing demands. In the broader semiconductor startup sector, investors have poured roughly $10.7 billion into seed-through-pre-IPO rounds in 2026. Notable valuations include Etched's $21 billion valuation following a $1 billion raise across two rounds in July and August.
On the radar
- OpenAI Funding Round: Reports indicate OpenAI is close to completing a $30 billion funding round led by UAE investors, which would value the company at $1.25 trillion. This massive capital injection could further intensify the demand for high-performance inference chips.
- Arda AI Manufacturing Startup: Former OpenAI research head Bob McGrew's startup, Arda, raised $230 million at a $1.5 billion valuation, signaling investor interest in AI manufacturing and infrastructure beyond just chip design.
- CoreWeave Insider Sales: CoreWeave founders have sold $3.3 billion in stock since their IPO, reflecting broader caution among investors regarding AI infrastructure spending.
