Which social-media company joined the $1 trillion market-capitalization club in January 2024?

The story behind the answer

Meta Platforms joined the $1 trillion market-capitalization club in January 2024.

Meta’s shares rose above the level required for a $1 trillion valuation on January 24, 2024. The milestone followed a strong recovery in investor confidence, helped by improved operating efficiency, large-scale digital advertising, and continued growth across its major platforms.

Meta Platforms was known as Facebook until it changed its corporate name in October 2021. Its family of apps includes Facebook, Instagram, Messenger, and WhatsApp. The company also operates Reality Labs, which develops virtual- and augmented-reality products.

Meta first reached a $1 trillion valuation in 2021, later falling below that level before returning to it in 2024. This illustrates why market-cap club membership is not permanent: share prices change every trading day, while the number of shares can also change through buybacks, issuance, or stock-based compensation.
