Anthropic confirms $30B Series G at $380B valuation after months of upsizing

What’s the deal? Anthropic has confirmed the close of its Series G, raising $30B at a $380B post-money valuation — one of the largest private financings in tech. The announcement formalises months of reports: the round was first cited at $10B in January at a $350B post-money valuation, then reported to exceed $20B in February.

The final terms represent a sharp increase in both size and pricing. The capital will fund research, expand compute capacity, and accelerate commercial growth.

Why now? The confirmation comes as competition among frontier AI labs intensifies. Building and deploying advanced models requires sustained investment in chips, infrastructure, and specialised talent.

Locking in $30B strengthens Anthropic’s position ahead of a potential IPO widely expected as early as late 2026 or 2027.

What could go wrong? A $380B valuation sets a high bar. Anthropic must translate technical leadership and scale into durable revenue and margins.

Regulatory scrutiny may also increase as governments in the US, UK, and EU tighten oversight of powerful AI systems and market concentration.

The signal: The progression from $10B to $30B within weeks highlights how AI mega-rounds are evolving in real time. Capital is concentrating at the top, with investors repeatedly upsizing commitments to a small group of model makers.

Even as venture funding remains tight elsewhere, frontier AI continues to command record-breaking sums — widening the gap between infrastructure-heavy AI leaders and the broader startup market.
