Circle Arc Launches AI Blockchain Amid Scalability Risks

| coingeek.com
Circle Arc has launched its public mainnet as a Layer-1 blockchain for human and AI-agent transactions. Arc uses USDC as its native payment and fee token, linking network activity to USDC demand. Circle says USDC represents 98.6% of agentic AI payment volume, while TRM Labs estimates a 99.6% share of value settled through the x402 protocol since May 2025. However, genuinely AI-driven payments account for only 0.6% to 7.5% of x402 activity, with current volumes of roughly $5,000 to $11,000 per month. Circle previously raised $222 million in a private ARC token sale at $0.30, implying a valuation of about $3 billion. It has now minted 10 billion ARC tokens but has not decided whether ARC will be publicly offered. Arc processes more than 3,000 transactions per second, with a target of 100,000 TPS, while Circle’s Malachite consensus engine is designed to provide sub-second deterministic finality. The network may eventually adopt proof of stake, and institutional validators include BlackRock, Visa and Mastercard. Circle has also launched a BTC-backed borrowing service that lets customers mint Circle Wrapped Bitcoin and borrow USDC without selling BTC. Competition is increasing as Tether develops its Stable blockchain, while major technology firms explore stablecoins, tokenized deposits and blockchain infrastructure. For crypto traders, Arc has long-term potential to increase ARC and USDC demand, but limited real-world payment activity, uncertain ARC availability, scalability concerns, regulation and strong competition make the near-term market impact neutral.
Neutral
The Arc mainnet launch and institutional validator support could improve confidence in Circle’s blockchain strategy and create long-term demand for ARC and USDC if AI-agent payments scale. However, current payment volumes are very small, genuinely autonomous activity remains limited, and ARC’s public trading status is unresolved. Arc also faces substantial competition from other stablecoin and blockchain networks. Its current throughput is above 3,000 TPS, but the gap to Circle’s 100,000 TPS target and much higher potential AI-agent demand highlights execution and congestion risks. Short-term traders may therefore see limited direct price support, while long-term sentiment will depend on developer adoption, liquidity, regulatory progress and measurable transaction growth. The combined factors support a neutral view rather than a clear bullish or bearish signal.
