OpenAI Hits $5 Trillion Valuation After GPT-5 Launch – Bigger Than Apple

The $5 Trillion AI Giant
OpenAI has achieved the unthinkable — a $5 trillion valuation that surpasses Apple and Microsoft combined. The milestone was reached after GPT-5's launch sent shockwaves through global markets, with sovereign wealth funds from Saudi Arabia, Singapore, and Norway leading a $500 billion funding round. Sam Altman, the company's CEO, has become the world's first trillionaire, owning 1% of the now-publicly-traded AI powerhouse. The valuation reflects OpenAI's dominance in artificial general intelligence, with GPT-5 passing every human benchmark and demonstrating capabilities that border on sentience.
Microsoft, OpenAI's largest investor, has seen its $1 trillion stake in the company grow to $500 billion — more than its entire cloud computing division. The partnership that began with a $10 billion investment in 2023 has created the most valuable tech alliance in history. Nvidia, the exclusive chip supplier for OpenAI's supercomputers, has also benefited massively, with Jensen Huang's wealth growing $120 billion from the AI boom. The funding round was oversubscribed 12x, with investors willing to pay $5 trillion for a company that generated just $3.5 billion in revenue last year.
GPT-5: The Game-Changer
GPT-5's capabilities have exceeded even the most optimistic predictions. The model can now write entire software applications from natural language descriptions, diagnose medical conditions with 98% accuracy, and generate photorealistic videos from text prompts. OpenAI's enterprise customers — including Goldman Sachs, JPMorgan, and McKinsey — report productivity gains of 400% using the new model. The company's API usage has grown 1,200% year-over-year, with 85% of Fortune 500 companies now paying for access. Altman has stated that GPT-5 represents 'the beginning of the intelligence age,' with plans to integrate the model into every digital interface worldwide.
