Anthropic's Claude doubles paying users, finds smart contract zero-days

Anthropic's Claude more than doubled its paid subscribers in the first quarter of 2026. The company confirmed the milestone as of March. Its global mobile market share climbed from 5.1% in February to 10% in April.

On iOS, 13% of Claude users pay for a subscription. For ChatGPT that figure is 8%. Claude generates $2.76 per user. ChatGPT brings in $1.74. The revenue advantage is roughly 1.5x.

Anthropic closed a $30 billion Series G round in February at a $380 billion valuation. Annualized revenue jumped from roughly $5 billion in August 2025 to over $30 billion by April 2026.

The newer Claude models – Fable 5 and the Mythos class – have autonomously identified zero-day vulnerabilities in cryptographic libraries and deployed smart contracts. Over $840 million in crypto hacks have been reported so far in 2026, according to industry trackers. Developers are already using Claude to audit code. Its ability to find zero-day flaws in smart contracts means the same tools that write code can now break it.

Anthropic shares trade on Solana through PreStocks, a platform that tokenizes equity in private companies. The token, listed as ANTHROPIC, was trading at an implied valuation around $700 to $750 per share in mid-June. Market capitalization sat near $7 million. Volume is small. The existence of a liquid market for private Anthropic equity shows how crypto rails expand access to high-growth tech names before traditional IPOs.

Over $840 million in crypto hacks have been reported so far in 2026. That makes the crypto market security landscape a direct frontier for AI capabilities.
