Stablecoin Supply Has Flatlined at $305 Billion After 12 Months of Rapid Growth

Artemis data shows total stablecoin supply has leveled off near $305 billion since October 2025 after 12 consecutive months of expansion, with USDT maintaining dominance while USDC gradually reclaims market share.

What the Data Shows

The Artemis stablecoin supply chart covering August 2020 through March 2026 shows one of the cleaner trend breaks in the dataset. From roughly August 2024 through October 2025, stablecoin supply grew almost without interruption, climbing from near $150 billion to $305 billion in approximately 14 months. That expansion nearly doubled total stablecoin supply in just over a year.

Then it stopped. Since October 2025, the bar chart shows supply flatlined in the $300 billion to $305 billion range, with no meaningful growth in either direction across five months. The vertical growth of 2024 to mid-2025 has given way to a horizontal plateau.

The stacked composition of the bars tells the internal story. USDT in green dominates throughout the full chart, representing the largest single slice at every point in the timeline. USDC in blue has been the second-largest component and its share has been gradually growing relative to USDT over recent months, a quiet market share recovery that doesn’t show up in headlines but is visible in the proportional shift across the most recent bars.

Why Supply Paused

Stablecoin supply expanding means more dollars are entering the crypto ecosystem via stablecoin minting. Stablecoin supply flatlining means that inflow has slowed to roughly match outflows from redemptions. It does not necessarily mean capital is leaving. It means the net addition of new dollars has paused.

The October 2025 timing is not coincidental. Bitcoin peaked near $126,000 in that same period before beginning its five-month decline. The institutions and traders who were minting stablecoins to deploy into crypto assets through the bull run reduced that activity as price started declining. Why mint new USDT to buy assets that are falling?

The $305 billion level is itself a record, and total liquidity remaining at that level through a significant market correction suggests the capital is staying on-chain rather than exiting to fiat. It is sitting, not leaving. That distinction is relevant for what happens when market sentiment shifts. A $305 billion stablecoin base represents potential buying power that can deploy quickly without requiring new capital to enter the ecosystem first.

USDT vs USDC

USDT’s green dominance across the full chart reflects its years-long position as the primary stablecoin for trading volume, particularly in Asian markets and on Binance. The Tron stablecoin flow data covered earlier this week showed USDT on Tron adding $1.6 billion in February alone, consistent with the continued strength of USDT in the high-frequency, low-cost transaction category.

USDC’s gradual market share recovery is a slower-moving story. The MiCA compliance framework in Europe creates a structural advantage for USDC relative to USDT in regulated European contexts, since Circle has pursued regulatory compliance more aggressively than Tether. The institutional use cases that the Qivalis consortium is targeting for their euro stablecoin, cross-border B2B payments and trade settlement, are also the use cases where USDC has historically been stronger than USDT.

Whether USDC’s share gains accelerate if the CLARITY Act passes and creates clearer US regulatory framework for stablecoins is one of the more interesting downstream effects of that legislation.
