[AI Agent Economy Infrastructure Fully Ready by January 2026] In January 2026, the AI agent economy will reach a critical milestone, with the foundational layers of payment, trust, and social collaboration achieving production-ready status. The x402 system processes over 20 million transactions, ERC-8004 goes live on the Ethereum mainnet, and 1.2 million autonomous agents register on Moltbook. Plandex's GitHub stars surpass 100,000, attracting 2 million developer visits. The ERC-8004 trust standard supports identity, reputation, and verification registries, with 30,000 agents completing mainnet registration. Currently, the development on the demand side faces three major obstacles: the absence of unified search indexing, insufficient capability validation, and the lack of trust-controlled payment middleware. Developers should focus on building unified indexing, capability benchmarking, and trust-controlled middleware to drive the transition from protocol readiness to product readiness.
