Arc has taken the top spot among chains for stablecoin market-cap growth over the past 30 days.
The network added $525 million in stablecoin value during that window, according to Token Terminal data released on Tuesday, 27th October, 2026.
That figure places Arc ahead of every other tracked chain and continues a pattern of rapid expansion since its public mainnet launch in mid-September.
What Is Arc and Why Does Its Stablecoin Growth Stand Out?
Arc is the Layer-1 blockchain built by Circle, the issuer of USDC. The chain uses USDC as its gas token, delivers sub-second finality, and runs with a permissioned set of institutional validators that includes names such as BlackRock, Visa and Mastercard.
Meanwhile, the design targets payments, settlement and tokenized finance rather than general-purpose activity.
In addition, nearly all of the stablecoin supply on Arc consists of USDC itself, which currently accounts for more than 98% of the chain’s total.
How Large Has Arc’s Stablecoin Market Cap Become?
DefiLlama figures from the same day put Arc’s total stablecoin market cap near $994 million.
The 30-day addition of $525 million therefore represents a substantial share of the current total and reflects both native minting and cross-chain transfers.
Further, weekly numbers have also stayed strong, with recent seven-day gains still measured in the hundreds of millions.
Still, the bulk of the capital remains concentrated in USDC rather than a diversified set of stablecoins.
Why Are Institutions and Users Moving Stablecoins onto Arc?
Circle launched Arc with more than 100 ecosystem and institutional partners already prepared.
The ability to pay fees in USDC removes the need to hold a separate volatile token, while the short finality times and institutional validator set appeal to regulated entities.
Moreover, lending protocols such as Aave and Morpho went live early, giving the stablecoins immediate utility beyond simple transfers.
Even so, activity metrics show that daily active wallets have cooled from the launch-day peak, suggesting the capital growth has outpaced broader user growth for now.
What Does Arc’s Lead Mean for the Wider Stablecoin Landscape?
Arc’s $525 million gain demonstrates that a purpose-built stablecoin chain can capture meaningful share even in a mature market.
The concentration of USDC also tightens the link between Circle’s own token and the network it operates.
Later data as we head deep into Q4 will show whether the pace continues once the initial partner liquidity fully settles.
At the moment, the Token Terminal ranking confirms Arc as the clear leader in stablecoin market-cap growth over the past month.
