AI Infrastructure Research Author
TheBigBerbowski (@TheBigBerbowski) is a pseudonymous retail investor and researcher who covers AI infrastructure on X and in the Substack newsletter TheBigBerbowski Investing, published since April 2026. The account's X profile and newsletter describe the author as a software product manager with a background in IT, sales and economics, covering data centers, memory and storage, networking, energy and cooling, and microcaps in other sectors. Deep dives follow a fixed structure of company overview, moat, financials and bear, base and bull cases; the newsletter also publishes earnings and investor-event reviews, a series of interviews with other retail investors, and portfolio updates. The author calls the newsletter a research publication rather than a trade-calling service and posts trade updates on X instead.
