OpenAI closed a $122 billion funding round on April 2, marking the largest raise in its history, with backing from major investors including Amazon, NVIDIA, and SoftBank Group.
The company’s revenue has seen strong growth, reaching about $20 billion by the end of 2025 and rising further in early 2026. Enterprise customers now contribute a significant share, crossing 40% of total revenue. Demand for its AI tools continues to grow, with increasing usage of its APIs and developer platforms such as Codex.
Founded in 2015 by Sam Altman and others, OpenAI started as a nonprofit before moving to a capped-profit model in 2019. The company has recently launched new AI models and developer tools and expanded its presence through acquisitions.
At the same time, the rapid scale comes with challenges. The cost of running large AI systems remains high, and margins are under pressure. OpenAI also operates under a long-term partnership with Microsoft, which shares in its revenue.
Competition in the sector is intensifying, with companies like Anthropic growing quickly. As the generative AI market expands, the focus is shifting from pure growth to building more sustainable and efficient operations.
