Meta Platforms

Meta's roughly $1.7 trillion market cap marks one of the most remarkable turnarounds in stock market history, recovering from a roughly $700 billion value wipeout in 2022. Its family of apps — Facebook, Instagram, WhatsApp, and Threads — reaches over 3.3 billion daily active users. Meta's open-source Llama models, downloaded over 600 million times, have also established the company as a top contender in enterprise AI.
