Cerebras completes IPO round trip
Cerebras Systems' stock has fallen back to its initial public offering price of $185 per share, down from a day-one opening of $350 in May 2026. This return to the offer price marks the completion of a significant public-market experiment, providing the first concrete data point on how AI compute businesses are valued once initial narrative premiums wear off.
Moore Threads crashes 20% on lockup expiry
Moore Threads, often cited as China's primary Nvidia challenger, saw its shares plunge approximately 20% around September 7, 2026. The selloff was triggered by the expiration of a lockup period for 25.77 million shares from its initial and follow-on offerings, leading to a record low since listing. This event highlights the divergence between the hype surrounding domestic GPU production and current capital pricing logic.

The company set its issue price at 142.18 RMB per share, aiming to raise approximately 6.12 billion RMB ($860 million) at a valuation corresponding to a static price-to-sales ratio of 61.80x for 2025. This listing is part of the "Four Little Dragons" of domestic GPU companies completing their capital market debuts.

Local view

Phoenix Finance (Ifeng) highlighted the "big meat sign" (a colloquial term for highly anticipated IPOs) of Suiyuan Technology, noting its Friday listing date and the specific P/S ratio metrics used to justify its valuation. Huxiu analyzed the broader sentiment, describing the market as experiencing a "shiver" as the most expensive batch of Chinese chip companies faced simultaneous pressure from lockup expiries and valuation corrections.
