The AI crypto sector in April 2026 is dominated by tokens powering blockchain-native AI infrastructure including compute, data, model training, and agent coordination. Bittensor leads as the dominant AI token by market cap at approximately $3.2-3.4 billion, surging 106% in 30 days with trading volume exceeding $881 million. The network now supports up to 128 specialized subnets, with Subnet 64 introducing serverless AI compute capabilities. Virtuals Protocol, built on Base, enables creation and monetization of autonomous AI agents, with its Agent Commerce Protocol launching live integrations across Arbitrum, XRP Ledger, and BNB Chain. NEAR Protocol has integrated AI into developer tooling with automated smart contract generation and AI-powered code debugging, building transaction infrastructure for autonomous agents. The sector represents a shift from retrofitting AI onto existing infrastructure to building native AI-blockchain integration from the ground up.
