USDC Has Added $4.5B in Supply This Year While USDT Lost Ground

The stablecoin market is not growing evenly in 2026. One issuer is pulling away while the market leader is contracting.

What the Chart Measures

The Artemis chart tracking top stablecoin supply changes year-to-date measures net change in circulating supply by absolute value in USD. It is not a snapshot of total market cap. It shows which stablecoins are being minted in excess of redemptions and which are seeing more redemptions than new issuance. Supply growth indicates demand for a stablecoin is increasing. Supply contraction indicates redemptions are outpacing new minting.

USDC Leads by a Wide Margin

USDC recorded a $4.5 billion net supply increase year-to-date, the largest positive flow of any stablecoin on the chart by a significant margin. The bar extending to the right of the zero line is visibly longer than every other positive entry, placing USDC in a category of its own in terms of new demand capture in 2026.

USDS, USD1, USYC, JTRSY, and PYUSD all recorded positive supply changes year-to-date, with their bars sitting between roughly $500 million and $1.5 billion in net growth. Each of those represents meaningful expansion, but none approaches USDC’s figure. The cluster of newer and yield-bearing stablecoins growing supply simultaneously suggests the overall market for regulated and compliant dollar-pegged assets is expanding, with USDC capturing the largest single share of that growth.

USDT Is Contracting

The most structurally significant data point on the chart sits at the bottom. USDT, the largest stablecoin by total market cap, recorded a net supply decrease year-to-date of approximately $2 billion, the largest negative bar on the chart. USDai, USDFALCON, and M also recorded modest supply contractions, but USDT’s negative reading dwarfs the others in absolute terms.

USDT contracting while USDC grows is not a new trend in 2026, but the scale visible in the year-to-date data is notable. USDT’s dominance in total stablecoin supply has historically been built on its role in emerging market remittance, offshore dollar access, and trading pair liquidity across centralized exchanges. Those use cases have not disappeared, but the direction of supply change suggests demand at the margin is moving toward USDC.

Why the Gap Is Widening

The regulatory context covered in earlier reporting this week is directly relevant here. The CLARITY Act’s progress toward resolved stablecoin yield rules, combined with the SEC and CFTC’s joint classification of major digital assets as commodities, has created an environment that favors regulated and compliant infrastructure. USDC, issued by Circle and subject to US regulatory oversight, is structurally better positioned than USDT to benefit from institutional demand in that environment.

As reported earlier this week, USDC has also overtaken USDT as the most-used stablecoin among institutions in the context of GENIUS Act compliance considerations. The supply flow data from Artemis is consistent with that institutional preference translating into actual minting demand rather than just stated preference. Supply change is behavior, not opinion.

The combination of USDC’s $4.5 billion supply gain against USDT’s approximately $2 billion supply loss year-to-date represents a net shift of roughly $6.5 billion in relative positioning between the two largest stablecoins in less than three months. That is a meaningful redistribution at the market structure level, not a rounding error.
