Meta Platforms

Meta's $1.7 trillion market cap marks one of the most remarkable turnarounds in stock market history, recovering from a $700 billion value wipeout in 2022. Its family of apps—Facebook, Instagram, WhatsApp, and Threads—reaches over 3.3 billion daily active users, a scale 2x larger than Amazon's Alexa user base, and its AI-powered advertising system has pushed advertiser ROI 30% higher than the industry average. Meta's open-source Llama models, downloaded over 600 million times, have also established the company as a top contender in enterprise AI, outpacing #2's model adoption by 20 percentage points.
