Four Weeks After Launch, Circle's Arc Holds 12% Less USDC Than on Day One
Arc, Circle's own blockchain, launched on September 16 and its first week was read as a growth story. The chain held US$649.18M of USDC at the end of launch day, and 81.76% of the USDC minted onto it in that window went to a single address. Four weeks later Arc holds US$571.06M, 12.03% less, after falling as low as US$451.75M. Outside demand has yet to add to the launch allocation.
- USDC on Arc rose from US$4.51M at the September 14 close to US$649.18M at the September 16 launch-day close. Of the US$667.94M minted in that window, US$546.12M (81.76%) went to a single address, which has since passed almost all of it on. see data →
- No daily close since has been higher. Supply fell to US$451.75M by September 27, 30.41% below launch day, including a US$103.85M drop on September 24 alone.
- At the October 13 close Arc held US$571.06M of USDC, 12.03% below its launch-day balance, after a partial recovery from the late-September low.
Arc is Circle's biggest strategic bet since USDC itself, and the market has been grading it on the simplest number available: how much USDC sits on the chain. On that number, Arc looked like a breakout, with its first week reported as topping the stablecoin growth tables. The start was one allocation, not a crowd: 81.76% of the USDC minted onto Arc in its launch window went to a single address, and the US$649.18M the chain held at the close of launch day matches the figure reported as Circle's own deployment. Four weeks later the chain holds US$571.06M, 12.03% less. So far, the growth figure has measured a launch allocation, not the chain's users.
That distinction matters to anyone using Arc as a read on Circle's strategy. The chain is Circle's bid to own the venue where its dollar settles, not only the dollar, with BlackRock, Visa and Mastercard among its founding validators. A new chain can be seeded with any amount of its sponsor's token. What cannot be manufactured is outside money choosing to stay there, and on that measure Arc's balance is still below the starting line.

USDC on Arc peaked at the close of launch day
USDC on Arc at each daily close, September 14 to October 13, 2026. The launch-day close of US$649.18M is the highest; the low was US$451.75M on September 27.
A launch balance, then a month below it
USDC on Arc stood at US$4.51M at the September 14 close, the residue of the pre-launch period. It reached US$134.38M a day later and US$649.18M at the close of September 16, launch day. It has not closed higher since. Supply held near US$620M for a week, then fell US$103.85M on September 24 alone and kept falling to US$451.75M on September 27, 30.41% below launch day. From there it recovered to US$571.06M by October 13, a 26.41% rebound that still leaves the chain short of its launch-day balance.
The address that received most of the launch USDC carries no public label, and it has since passed almost all of it on: it held US$10.40M on October 14. The chain does not show who moved USDC off Arc, and part of the decline may be that launch allocation being redeployed rather than outside holders leaving. Either reading leads to the same place: four weeks in, the supply on Arc has not risen above the launch allocation. USDC itself is not the constraint. Circle's dollar had about US$74B in circulation when Arc went live, so the chain holds well under 1% of it.
What would show real traction
The signal to watch is a close above US$649.18M. That is the first point at which Arc would hold more USDC than it started with, and the first evidence that institutions, payment firms or traders are bringing their own dollars to the chain. Until then, every headline about Arc's growth is a headline about its launch allocation. The open question for Circle, and for anyone valuing its move into infrastructure, is whether a stablecoin issuer can pull the dollar it issues onto a chain it controls, or whether USDC will keep settling where its users already are.
