10月28日 - ** 芯片公司Cerebras Systems（股票代码： CBRS.O）股价下跌4.7%至113.67美元，此前Culper Research披露了做空头寸
** Culper表示，其认为该公司覆盖整片硅晶圆的旗舰产品“晶圆级引擎”（Wafer Scale Engine）芯片，在实际使用中的寿命“仅为1.2至2.5年”
** 该机构声称CBRS从未解决热膨胀问题，并指控其持续进行的虚拟运算导致晶圆过热，“以致晶圆实际上从未真正冷却下来”
** “这种临时拼凑的权宜之计只是用一个致命缺陷换了另一个：晶圆永远无法冷却，并在实际使用中迅速损坏”——Culper
** 路透社无法独立核实该报告中的说法
** CBRS 未立即回应路透社的置评请求
** 截至上一交易日收盘，该股自5月在纳斯达克上市以来已下跌61.6%
