Deferred revenue was $1.12 billion and $1.08 billion as of March 31, 2026 and December 31, 2025, respectively. Our deferred revenue mostly relates to advertising prepayments and credits, as well as software updates and upgrades associated with Reality Labs hardware sales, substantially all of which are expected to be realized in less than a year.
