#IBM’s announcement of a 0.7-nanometer (7 angstrom) "Nanostack" 3D MO transistor architecture has profound implications for #Cerebras.
#CBRS is famous for its Wafer-Scale Engine (WSE), which eschews traditional small dies in favor of manufacturing the world's largest single-wafer
#CBRS historically manufactures its giant chips exclusively with #TSMC due to TSMC's advanced lithography and packaging capabilities.
For #CBRS to exploit sub-1nm architecture, they will either have to wait for #TSMC to develop a competing sub-1nm/3D roadmap
Our assessment: $3.3B cash war chest from massive $6.4b IPO and OpenAI loans,#CBRS has won the validation phase. Next 18 mths will be about execution—proving they can build out infrastructure fast enough to convert $24b backlog into high-margin rev w/o drowning in ops cash burn
Severe Customer Concentration: In 2024, G42 was 85% of rev. In 2025, MBZUAI (an associated entity) was 62%. Moving forward, #OpenAI represents vast majority of backlog. If any of these anchor customers slow down their spending, #Cerebras' top line faces immediate exposure
