Circle's Arc blockchain has reached a milestone of $1 billion in USDC supply. This figure was first surpassed on October 27, 2026, approximately six weeks after the network's public mainnet launch on September 16, 2026.
Data from trackers such as usdc.cool and DefiLlama indicate that the supply of USDC on the network increased by 109.4% over a 30-day period. By early November 2026, the total stablecoin supply on Arc reached approximately $1.098 billion, with USDC accounting for $1.088 billion.
Current estimates place the USDC supply on Arc between $1.003 billion and $1.1 billion. This growth occurred during a period when the global stablecoin market experienced a contraction.
Analysis of the network shows that the top four addresses hold approximately 73% of the total USDC supply. While the identity of these holders remains undisclosed, the concentration suggests that a significant portion of the liquidity is held by a limited number of entities.
Circle's Arc network remains heavily reliant on a single asset, with USDC representing 99.18% of the total stablecoin supply. Future developments will focus on whether this growth rate persists and if the concentration of holdings decreases.
