The Growth Metrics

Amol Avasare is Head of Growth at Anthropic, which is going through the most unprecedented growth trajectory in history—scaling from $1 billion to over $19 billion in ARR in just 14 months.

This isn't just growth. It's explosive growth. Rival Anthropic is approaching $19 billion in annualized revenue. For context: Slack took 5 years to hit $100M ARR. Anthropic did it in months.

The Product-Market Fit

Anthropic released Sonnet 4.6 delivers frontier performance across coding, agents, and professional work at scale. We're upgrading our smartest model. Across agentic coding, computer use, tool use, search, and finance, Opus 4.6 is an industry-leading model, often by wide margin.

The enterprise is voting with its wallet. Anthropic's models are being embedded into production systems at scale.

The Safety Paradox

An Anthropic spokesperson said the new model represents "a step change" in AI performance and is "the most capable we've built to date." A draft blog post that was available in an unsecured and publicly searchable data store prior to Thursday evening said the new model is called Claude Mythos and that the company believes it poses unprecedented cybersecurity risks.

So Anthropic's messaging is: we're the fastest-growing AI company ever, our models are industry-leading, and they pose unprecedented cybersecurity risks. Both true? Possibly. Confusing? Absolutely.

The Politics

On Mar 31, 2026 Anthropic signed MOU for AI safety and research with the Australian government, and on Mar 12, 2026 Anthropic invested $100 million into the Claude Partner Network. They're playing the long game: government relationships + developer ecosystem.

My Take: Anthropic has cracked something venture capital has chased for a decade: defensible enterprise moat + network effects. Claude is becoming infrastructure. But every fast-scaling company faces a critical test: can execution velocity match ambition velocity? The leaked source code and Mythos warnings suggest internal pressures may be mounting.
