An update on AI's most important number (epochai.substack.com)

OpenAI and Anthropic have reported unprecedented revenue growth, significantly impacting the AI/ML industry. OpenAI's revenue run rate soared from $13 billion to over $40 billion in just a year, while Anthropic accelerated from $1 billion to an astonishing $65 billion within six months. Together, these leading firms achieved combined revenues of $105 billion by August 2026, marking an astonishing tripling compared to the previous year. This rare growth trajectory, where companies surpass a revenue threshold of $1 billion while maintaining over 100% year-on-year growth, is particularly striking as it’s generally perceived as unsustainable in established tech sectors. The implications for the AI landscape are profound. The sustained revenue growth suggests a robust demand for advanced AI capabilities, fueled by notable advancements in large language models (LLMs) and coding agents. However, as these companies scale, industry analysts warn that acceleration may soon taper off, anticipating a maturation phase akin to other tech sectors. Whether this growth is a result of immediate advancements or a reflection of widespread adoption will be crucial in determining the future of AI. If current trends persist, the combined revenue of frontier AI companies could potentially reshape the global economy, hinting at the transformative power of AI technologies and their capability to automate tasks across various sectors.
