How Self-Storage Became a $39 Billion Empire

Public Storage held the title of America's largest self-storage company for nearly 20 years — until a $12.7 billion deal changed everything. This is the real story behind why storage units are on every corner in America, and what happens when an industry builds faster than demand can keep up. We follow the money trail behind Public Storage, Extra Space Storage, and the Life Storage merger — from record pandemic-era profits to the supply glut that's slowing the entire industry down in 2025. Self-storage looks like the most boring business in America — a shed with a lock on it. But behind roughly 52,300 facilities and 2.1 billion square feet of rentable space sits a multi-billion-dollar Wall Street asset class, built on REIT tax structures, cheap real estate economics, and a decade-long building boom that may have gone too far.
