Stablecoin supply tops $300B: Is crypto finally breaking into banking?

The stablecoin market has surged to a record high, crossing the $300 billion milestone after months of steady expansion in 2025.

Data from CoinMarketCap shows that the total supply now stands at $307 billion, cementing stablecoins as one of the fastest-growing segments of the crypto sector.

Other data providers confirm the upward trajectory, though with slight variations. CoinGecko tracks stablecoin supply at $299 billion, while DeFiLlama reports $295.5 billion.

Regardless of the source, the industry’s rapid climb toward the $300 billion level reflects accelerating adoption across global markets.

Tether, Ethereum dominate stablecoins

Tether’s USDT continues to dominate the emerging sector, controlling 58% of the market with a capitalization of $173 billion. Tether CEO Paolo Ardoino noted that peer-to-peer use of USDT has scaled dramatically, with $17.4 billion now moving wallet-to-wallet daily, 130 times higher than in 2020.

Meanwhile, Circle’s USD Coin (USDC) follows with a $74 billion supply. Notably, the firm’s recent IPO success confirmed the significant appetite for the asset class, as it rallied to record highs in little time.

Ethena Labs’ USDe completes the top three, with its supply recently reaching a new record high of $14 billion thanks to listings on Binance.

Across blockchain networks, DeFillama data shows that most of the stablecoins are issued on Ethereum, which houses $161.782 billion worth of these stable assets.

It is followed by Justin Sun’s Tron network, which has a supply of $77 billion, while Solana and Binance-backed Smart Chain have supplies of $13 billion and $12 billion, respectively.

Why is stablecoin supply rising?

Patrick Scott, head of growth at DeFiLlama, emphasized that since the passage of the GENIUS Act in July, the supply of stablecoins has hit new highs nearly every week.

The law established federal reserve requirements and direct oversight by the Federal Reserve, reducing uncertainty that had weighed on the sector.

With these guardrails in place, crypto-focused firms like Ripple and MetaMask have made significant advancements in the sector.

At the same time, financial giants such as JPMorgan and regulators like the CFTC have accelerated their experiments with stablecoin-based settlement and cross-border payments.

Considering this, Scott concluded:

“Stablecoins have long been called a Trojan Horse for banks to enter crypto. But maybe they’re a Trojan Horse for crypto to enter banks. Once stablecoin rails are integrated, an infinite array of new businesses become possible. And once that door is open, savvy entrepreneurs will see this and use crypto as a platform to launch new businesses.”
