Anthropic Hits $30B ARR, Officially Surpasses OpenAI in Revenue While Spending 4x Less on Training
Anthropic's annualized recurring revenue reached $30 billion in April 2026, overtaking OpenAI's $24-25 billion and marking the first time the younger company has led on top-line run rate. The growth trajectory is staggering: from $1B in January 2025 to $30B just 15 months later, faster than Salesforce managed in 20 years. What makes this especially notable is that Anthropic achieved it while reportedly spending roughly a quarter of what OpenAI invests in model training, fueled instead by enterprise API contracts and cloud partnerships with AWS and Google Cloud. OpenAI's chief revenue officer disputes the $30B figure, claiming it's overstated by ~$8B due to different accounting treatments for cloud partner revenue.
