Cerebras Shares Hit Post-IPO Low Amid Lockup Expiration and Competitive Pressure
Cerebras Systems (CBRS) shares fell approximately 20% for the week ending October 2, reaching an all-time low since its May 2026 IPO. The decline was driven by the expiration of the initial insider lock-up period, allowing early holders to sell, combined with intense competitive pressure from Nvidia’s continued dominance in the inference market. Despite this, Cerebras holds a $25.4 billion contracted future revenue backlog, and some analysts argue the market is mispricing the stock’s long-term potential.
Cerebras CEO Pushes Back on AI Doomsday Narratives at TechCrunch Disrupt
On October 13, Cerebras CEO Andrew Feldman criticized the industry's focus on AI risks during TechCrunch Disrupt, arguing that doomsday warnings are obscuring the technology's potential benefits. Feldman emphasized that Cerebras is focused on delivering tangible performance gains in inference speed rather than engaging in speculative risk discourse. This stance comes as the company navigates a volatile post-IPO market environment.
Chinese AI Chip Startup MachinHeart Secures 1.625 Billion Yuan in First Funding Round
On October 16, Li Auto announced that its chip subsidiary, Shanghai MachinHeart Technology, completed a first-round equity financing of 1.625 billion RMB (approx. $230 million). The round was led by Hangzhou Jingtou, BlueRun Ventures, and Huaye Tiancheng. This move highlights the continued strength of capital inflows into specialized Chinese AI hardware startups, even as broader tech investment faces headwinds.
Global AI Investment Cools, Impacting Chinese Chip Stocks
Reports from October 17-18 indicate that the global AI investment boom is slowing, with Chinese AI-related stocks identified as significant losers. The cooling sentiment has affected valuations for domestic chipmakers, although specific recent funding events like MachinHeart’s suggest selective investor confidence remains in companies with clear automotive or industrial applications.
Local view
In China, media coverage focuses on the divergence between general AI sector cooling and specific successes in strategic hardware. Sina News highlighted MachinHeart’s funding as a key development in the "AI chip" category, noting the involvement of major state-affiliated and venture capital firms. Conversely, Epoch Times reported that Chinese companies are bearing the brunt of the global AI investment slowdown, with the Shanghai STAR Market underperforming expectations for chip IPOs.
Context & numbers
- Cerebras Backlog: $25.4 billion in contracted future revenue.
- Cerebras Stock Performance: Down ~52% from peak; hit all-time low in early October.
- MachinHeart Funding: 1.625 billion RMB (~$230 million).
- Sector Funding (2026 YTD): Approximately $10.7 billion has flowed into semiconductor startups in 2026.
On the radar
- Cerebras Analyst Revisions: Several Wall Street banks have recently issued price targets suggesting Cerebras could double from current lows, betting on the realization of its $25B backlog.
- Anthropic Valuation Rumors: Reports from October 16 suggest Anthropic’s expected valuation may have shrunk due to rising compute costs, which could indirectly affect demand forecasts for high-performance inference chips.
