"Lux Capital reflects on its 25-year history of investing at the intersection of physical and computational sciences, noting that the AI capex boom's value is ultimately anchored in physical constraints and real-world assets."
In their Q3 2025 Quarterly Letter, Lux Capital reflects on their twenty-five-year history, moving from humble beginnings during the dot-com bust to managing over $5 billion in capital. Celebrating this quarter-century milestone, the firm reiterates its core investment philosophy of operating at the intersection of life, physical, and computational sciences, guided by the central belief of investing before others understand. Looking at the current macroeconomic landscape, Lux highlights a widening divergence between digital abstractions and physical realities. They observe that while AI hyperscalers (including Microsoft, Meta, Amazon, Alphabet, Tesla, and Oracle) are projected to spend over $400 billion on capital expenditures, the ultimate value of the intangible economy remains anchored in tangible foundations. This includes massive demands on power grids, copper, water cooling, and specialized hardware like high-bandwidth memory. Consequently, Lux is highly constructive on physical constraints, emphasizing gold's 45% YTD rise and the rising importance of biodefense (such as their new de novo company Valthos) and aerospace/defense tech (evidenced by Anduril's success in autonomous aircraft). Conversely, they remain cautious on traditional IT service consulting firms facing AI-driven obsolescence and the potential for a massive, destructive over-investment cycle in general AI software.
