Airbnb is a publicly traded company (NASDAQ: ABNB), so "most" of it is owned by institutional investors rather than a single individual. As of early 2026, the Vanguard Group remains the largest shareholder, holding approximately 10% of the company, followed by BlackRock at roughly 7% and Fidelity (FMR) at 6%. However, the three co-founders—Brian Chesky, Joe Gebbia, and Nathan Blecharczyk—collectively retain about 15% of the outstanding shares. Brian Chesky, the CEO, holds the largest individual stake at roughly 9-10%. Because the founders hold specialized "Class B" shares, they maintain a disproportionate amount of voting power, effectively allowing them to control the company's strategic direction even though they do not own the majority of the total equity. This "dual-class" structure is common in 2026 tech giants to protect the founders' original "design-led" vision for the platform.
