YouTube closed 2025 with over $60 billion in combined ad and subscription revenue, while Alphabet exceeded $400 billion in total sales. Growth was fueled by traditional advertising on Search and YouTube, but the platform is increasingly monetizing subscriptions like Premium and YouTube TV. AI tools like Google Gemini now power 70 million creative assets, enhancing ad relevance and campaign efficiency. Rising capex — projected at $175–185B in 2026 — signals heavy investment in AI, leaving investors weighing growth against costs. YouTube continues leading streaming engagement, including major live events.
