Top developments
Tenstorrent Secures $1.5B at $6.2B Valuation
On October 19, 2026, Tenstorrent announced the completion of a $1.5 billion Series E funding round, led by Trace Capital and Innovation X, with participation from Morgan Stanley and ARK Invest. This round elevates the Toronto-founded company’s valuation to $6.2 billion, a significant increase from its $2.6 billion valuation in 2024. The capital will be used to expand AI server deployments and develop processor designs for customers building their own chips, reinforcing its position as a key challenger to Nvidia.
Cerebras Stock Falls Below IPO Price
Cerebras Systems saw its stock price drop below its $185 IPO price in mid-October 2026, driven by the expiration of lockup periods and a broader selloff in AI infrastructure stocks affecting peers like CoreWeave and Nvidia. Despite this volatility, the company remains a focal point for investors, with some analysts suggesting the current dip represents a buying opportunity if management can execute on its growth roadmap. The company has also announced that it will release its third-quarter 2026 financial results on October 22, 2026.
Inference Chip Valuations Soar
The valuation landscape for AI inference chip startups has intensified, with the median valuation for AI chip makers growing 9x in two years. This surge is largely driven by mega-rounds, such as Etched’s recent $1 billion raise across two rounds, which placed its valuation at $21 billion. These figures highlight the high stakes and investor appetite for companies that can deliver specialized inference hardware outside of the standard GPU paradigm.
Local view
Chinese tech media outlets, including Sina Tech and IT Home, have closely covered Tenstorrent’s $1.5 billion funding round, noting the significant valuation jump and the involvement of major investors like Morgan Stanley and ARK Invest. These reports highlight the global interest in non-GPU architectures as a hedge against Nvidia’s dominance. Additionally, local reports from Huxiu indicate that global startup funding reached $679 billion in the first three quarters of 2026, with US venture capital increasingly shifting towards AI compute and defense production capabilities.
