Stablecoins settled roughly $33 trillion in on-chain transaction value in 2025, up 72% year over year, on a market capitalization of about $300 billion, with USDC ($18.3 trillion) and USDT ($13.3 trillion) leading the flow, according to Artemis Analytics data reported by Bloomberg. By monthly volume, they now outpace Visa's throughput. That is what turned stablecoins from a trading tool into one of the largest settlement rails in the world.

Stablecoins are cryptocurrencies pegged to a stable asset, almost always the US dollar, so one token is designed to always be worth roughly $1. What follows covers the most-cited stablecoin statistics for 2026: total market cap, the USDT-versus-USDC split, how many people hold and use them, settlement volume against card rails, and real-world use cases. Every figure links to its source, and where the numbers are noisy or a comparison is imperfect, we say so rather than overstate precision.

The total value of all stablecoins in circulation is the headline measure of the sector's size.

The market added nearly $100 billion in the first nine months of 2025 alone, an average of over $11 billion per month, versus $70 billion added across all of 2024, according to Ark Invest. Longer-range forecasts vary widely, from JPMorgan's conservative $500-750 billion to Standard Chartered's $2 trillion by 2028. That spread reflects genuine uncertainty about how far regulated, bank-issued stablecoins will expand, not just optimism.

Two stablecoins dominate, together holding over 80% of all supply. But the split hides something most summaries miss.

Market-cap and share figures are from Ark Invest; 2025 transaction values are from Artemis via Bloomberg. Here is the inversion: USDT has roughly 2.4x USDC's market cap, yet USDC moved more value on-chain in 2025. The two tokens play different roles. USDT is held as a dollar store-of-value in emerging markets, while USDC circulates more heavily through US-regulated venues, institutional flows, and DeFi. Market cap measures how much is parked; transaction value measures how hard it works. Read only one number and you miss half the picture.

Because most balances sit in custodial and exchange wallets, "users" and "active addresses" are measured, not counted as people. The available data still shows sharp growth.

• Active stablecoin wallets grew 53% in a year, from 19.6 million in February 2024 to over 30 million in February 2025, according to the Dune and Artemis "State of Stablecoins 2025" report, via AltcoinBuzz.
• Visa reported around 47 million monthly active stablecoin users across all chains, though that figure is dated as of April 2024, per Visa, so the real 2026 number is likely higher.
• Stablecoins account for roughly 40% of total cryptocurrency trading volume as of 2024-2025, per CoinLedger.

Address counts are a rough proxy for people, and they mislead in both directions. A single custodial wallet at a large exchange can represent millions of individual users (understating the true count), while one active trader can control dozens of self-custody addresses (overstating it). Treat "30 million active wallets" as an order-of-magnitude signal, not a census. This adoption sits within a broader base of 741 million crypto owners worldwide in 2025, up 12.4% year over year, per Crypto.com; see our how many people own crypto breakdown.

This asset class now moves value on a scale that rivals the largest card networks.

• Stablecoins settled about $33 trillion in on-chain volume in 2025, up 72% year over year, per Artemis via Bloomberg.
• Monthly stablecoin transfer volume reached $4.1 trillion in February 2025, already outpacing Visa's monthly card volume, according to the Dune and Artemis report via AltcoinBuzz.
• Monthly stablecoin transaction volume first crossed $1 trillion in September 2025, per Ark Invest.

One caveat before anyone quotes "$33 trillion beats Visa": raw on-chain volume includes automated activity like bots, arbitrage, and exchange rebalancing, so it isn't a like-for-like comparison with consumer card spending. Adjusted "organic" estimates are meaningfully lower, and different trackers report different headline totals depending on how aggressively they filter. Read it as directional, not a scoreboard. Stablecoins have graduated into the same order of magnitude as Visa and Mastercard, which was unthinkable a few years ago.

Stablecoins are increasingly used for payments and savings rather than just trading, and adoption is strongest in emerging markets. In Latin America, 71% of stablecoin activity is tied to cross-border payments, the highest share globally, versus 39% in North America, according to CoinLedger. There they serve as a dollar hedge against local-currency inflation and a cheap remittance channel, a use case we size up in our crypto remittance statistics. Regional token preference differs too: in India and Argentina, USDC accounts for roughly 47% of stablecoin usage, while in Turkey, China, and Japan, USDT dominates, per Artemis. On the commercial side, B2B stablecoin payments surged roughly 30x, from under $100 million to over $3 billion in monthly volume between early 2023 and 2025, according to Reap, citing Artemis research. For the broader payments shift, see our state of crypto payments 2026 report.

Stablecoins have become dollars that live on a blockchain. But most of that $33 trillion never touches a physical checkout; it moves between wallets, exchanges, and protocols. The gap between "settled on-chain" and "spent at a store" is the problem a card solves. Turning a stablecoin balance into everyday purchasing power takes an issuer that authorizes against your balance in real time on the Visa or Mastercard network. On SolCard, you load USDC or USDT over Solana, so top-ups settle in seconds for fractions of a cent, then spend at $1 anywhere those networks are accepted, with no bank withdrawal in between. Because the token is pegged to $1, spending it with a crypto debit card also sidesteps most of the capital-gains complexity of spending volatile assets like Bitcoin.

There is no exact headcount because balances pool in custodial wallets, but active on-chain stablecoin wallets grew from 19.6 million in early 2024 to over 30 million by early 2025 (Dune and Artemis, via AltcoinBuzz), and Visa cited roughly 47 million monthly active stablecoin users as of April 2024 (Visa). Both are rough proxies rather than a true user census.

About $300 billion in late 2025, up from roughly $205 billion at the start of the year, according to Ark Invest. Longer-term forecasts range from JPMorgan's $500-750 billion to Standard Chartered's $2 trillion by 2028.

By market cap, USDT (Tether) is much bigger: about $176 billion and ~58% share, versus USDC (Circle) at about $74 billion and ~25% share in late 2025, per Ark Invest. But by 2025 transaction value, USDC actually moved more ($18.3T vs $13.3T), per Artemis via Bloomberg. USDT is held more; USDC circulates more.

By raw on-chain volume, stablecoins hit about $33 trillion in 2025 (Artemis via Bloomberg), and monthly transfers had already outpaced Visa by February 2025 (Dune and Artemis). But raw on-chain totals include bot and exchange activity, so this is not directly comparable to consumer card spending. The fair statement is that stablecoins are now in the same league, not that they have "beaten" Visa.

Trading and DeFi remain large, but payments, savings, and remittances are the fastest-growing uses, especially in emerging markets where stablecoins offer a dollar hedge against inflation. Latin America leads in cross-border use (71% of activity), per CoinLedger, and B2B payments reached ~$3 billion monthly in 2025 (Reap).

Fast on both supply and volume. Market cap grew about 46% in 2025 (from ~$205B to ~$300B), adding over $11 billion per month, while transaction volume rose 72% year over year to ~$33 trillion, according to Ark Invest and Artemis via Bloomberg.

As of mid-2026, stablecoins are the dollar rail of crypto, and the natural next step is spending them like dollars. SolCard lets you load USDC or USDT and spend anywhere Visa and Mastercard are accepted, turning a stablecoin balance into everyday purchasing power without a bank withdrawal.
