Cerebras（CBRS）10月14日再解禁约1,940万股（约占总股本8%），但属IPO时已披露的分批锁定期日程，股价已提前重挫至历史新低
这是一次自IPO起就排定、9月21日已被媒体逐波列明的机械性分批解禁，不构成新增基本面事实；股价已处历史新低、周一单日-10.7%、5日-19%且明显跌破发行价，解禁抛压被提前且过度地计入，在已知事件前一日追空属于crowded trade，叠加潜在relief rally与空头挤压风险，期望收益为负。

不做 Cerebras Systems Inc.（CBRS.US）
不做空：本次1,940万股解禁是IPO时已公开、9月21日被逐波列明的日历事件，无增量信息；股价已提前暴跌（周一-10.7%、5日-19%、创历史新低、破发21%），抛压高度price-in，事件前一日追空为拥挤交易，易在落地时遭遇利空出尽反弹/逼空；9月30日同批-8.9%被同日OpenAI利空污染、无法归因于解禁，缺乏可校准的干净先例。不做多：事件本身为供给利空且基本面仍有OpenAI订单与自研芯片竞争的不确定性。

结论摘要
Cerebras周三解禁约1,940万股（约8%）虽是供给利空，但该分批日程自IPO起即公开，且股价已提前暴跌至历史新低、跌破发行价21%，利空高度price-in；在事件落地前一日追空赔率差、易遭利空出尽反弹，故不做。
消息传播链
- 提示周三1,940万股解禁；当日盘中CBRS约148美元微涨约1%，而前一日已暴跌10.7%创新低，说明抛压主要在事件前释放
关键理由
- 若做空：未来24小时确有8%股本转为可售、内部人近期持续按计划减持，供给压力方向偏空
- 但不做空的关键：解禁日历早被充分知晓（Nasdaq 9月21日已逐波列出），股价5日-19%、周一-10.7%创历史新低，抛压已被提前定价，事件落地反可能触发relief rally
主要风险
- 解禁≠强制卖出，持有人可能惜售，且分批设计本就为平滑抛压；已知事件落地常见sell-the-rumor/buy-the-news反弹（10月5日Altman单条推文即带来+9%），追空易被轧
- 周一-10.7%同时受微软Maia 300自研推理芯片、AI板块回调、OpenAI收入传闻驱动，无法用9月30日-8.9%推断单纯解禁效应，做空的归因基础薄弱
反向证据
- 做空前查反向 · 来源 web · 日期 2026-10-13 · 影响 weakens
10月5日Altman一条力挺合作的推文即令股价次日+9%；公司与OpenAI有逾200亿美元、750MW多年协议及10亿美元借款，且股价已处历史新低、20日波动与量比放大，做空在事件落地时面临利空出尽反弹与逼空风险

已知内部人卖出均通过预设交易计划进行，解禁并不等于新增强制抛售；无证据表明10月14日批次持有人会立即集中清仓，做空缺乏确定的新增卖盘触发

先例如何影响了这次决策
对本次决策的影响:先例不可靠+股价已提前大跌，直接支持放弃SHORT、不设追空参数
方向:没有可干净归因的同主体先例：9月30日同等规模1,940万股解禁当日-8.9%，但同日SemiAnalysis称OpenAI新推理模式改用英伟达GPU，当周累计跌近20%，无法把跌幅归因于解禁；不足以作为解禁效应的方向证据
涨幅量级:未向event_study喂入样本——唯一同主体观测被同日重大利空污染，跨公司解禁案例本轮未做一手溯源，强行用-8.9%校准做空止盈幅度会高估纯解禁冲击
形态:已知日历型解禁普遍呈现事件前承压、落地后利空出尽的特征，但本轮无可引用的干净首发先例面板，仅作背景不据以定tp/sl

Cerebras Systems Inc. (NASDAQ:CBRS) faces more potential selling when up to 19.4 million more shares become eligible for sale on Wednesday under the AI chipmaker’s staggered IPO lock-up.
The stock is on watch after sliding 10.7% to $146.62 on Monday, its lowest close yet, according to Benzinga Pro market data. Shares are down about 58% from their $350 opening price in May and trade roughly 21% below the $185 IPO price.

Lock-Up Clock Ticks
Cerebras set up its lock-up to release insider stock in stages rather than all at once, similar to SpaceX. The releases were planned in several rounds running through the end of October, Axios reported at the time of the IPO.
The last tranche of this size arrived Sept. 30. Up to 19.4 million shares held by directors, officers, employees and other holders unlocked that day, equal to 8% of shares outstanding. The stock fell 8.9% that day.
Before that, up to 14.6 million shares had been freed every two weeks since Aug. 19.
Insiders have been selling. CEO Andrew Feldman and CTO Sean Lie sold more than $240 million of Class A shares between Aug. 20 and Sept. 25 under trading plans, according to Benzinga’s insider sale data.
OpenAI Doubts Linger
The unlock comes on top of questions about Cerebras’ biggest customer. On Sept. 30, research firm SemiAnalysis said OpenAI would run the “Ultrafast” mode of GPT-6.1 Sol on NVIDIA Corp. (NASDAQ:NVDA) GPUs rather than on Cerebras hardware. Cerebras fell nearly 20% that week and closed at $166.43 on Oct. 2.
OpenAI CEO Sam Altman pushed back late that Friday.
“There is some speculation about our partnership with Cerebras. Cerebras is a close partner, and we have a deep engagement pushing on the frontiers of speed,” he wrote on X. The stock jumped 9% the following Monday. His post did not say which chips run the new tier.
Citi analysts said their 2026-2028 revenue outlook for Cerebras was “unchanged.” They called it “too early to read much into” the rollout, CNBC reported.
The two companies are closely tied. Cerebras has a multiyear deal worth more than $20 billion to supply OpenAI with 750 megawatts of computing power. OpenAI also lent Cerebras $1 billion and holds warrants for up to 33.4 million shares.
Altman Bounce Fades
Cerebras’ Altman bounce didn’t hold. Shares have fallen about 19% since closing at $181.55 on Oct. 5.
Pressure across the sector added to the losses. AI stocks slid Oct. 8 after reports that OpenAI’s annualized revenue at the end of September was about $18 billion below earlier figures.
On Monday, Microsoft Corp. (NASDAQ:MSFT) unveiled its Maia 300 chip and said it would become the main inference system for Microsoft’s own products. The Philadelphia Semiconductor Index dropped 2.7% the same day.
Inference is the core of Cerebras’ pitch, and each new in-house chip from a big cloud company makes the competitive question harder to ignore.
Cerebras is now worth about $34.8 billion. It was valued near $95 billion after its first day of trading.
CBRS Stock Price Activity: Cerebras stock was up 0.49% at $147.34 at the time of publication on Tuesday, according to Benzinga Pro.
