Source Foundry。据悉 VC 巨头红杉资本也为该初创公司提供支持，截至目前 Situational Awareness 与 Source Foundry 的代表均未回应置评请求，红杉资本则拒绝确认该对冲基金的投资情况。\n\n据悉，Source Foundry 致力于开发一种比现有方式更简单、成本更低、速度更快的半导体制造工艺，旨在弥合人工智能算力需求与芯片制造产能扩张能力之间日益扩大的差距。分析认为，Leopold Aschenbrenner 此次大规模投资折射出市场对新型芯片制造技术的持续旺盛需求，因为人工智能开发者对算力的需求正与日俱增。不过，这笔投资也揭示出 Situational Awareness 在其公开科技持仓遭遇剧烈波动、基金承受巨大财务压力之前，已形成高度集中的风险敞口。
