Stablecoin market share by aggregate supply, May 2026 snapshot. Top-2 concentration is structural: USDT (58%) plus USDC (24%) account for 82% of total supply. Ethena USDe (4.7%) is the largest synthetic dollar; Sky/DAI (2.5%) is the dominant crypto-backed alternative. The Other bucket includes BlackRock BUIDL, Hashnote USYC, Paxos USDP, TrueUSD, and the long tail. Initial v1; verify against DefiLlama.

Stablecoin Transfer Volume vs Visa

Monthly on-chain stablecoin transfer volume (adjusted to exclude MEV, sandwich attacks, and same-entity wallet moves) compared with Visa monthly purchase volume. The crossover happened in early 2024 alongside the spot BTC ETF launch and the broader stablecoin acceleration; the gap widened to roughly 3x by Q3 2025. Stablecoin volume is treasury/DeFi/CEX-internal-heavy versus Visa's consumer-spending focus, so direct comparison is imperfect.

Stablecoin Distribution by Chain (USDT and USDC)

Per-chain supply split for the two dominant US-dollar stablecoins. USDT is Tron-dominant (~50%) reflecting EM-dollar use cases in Argentina, Venezuela, Russia, and Asia remittance corridors. USDC is Ethereum-dominant (~53%) with strong Base growth (Coinbase distribution effect) and meaningful Solana penetration.

Stablecoin Reserve Composition

Tether vs Circle reserve-asset composition per their most recent attestations. Structurally different: Tether's reserves are a mixed portfolio (T-bills 60% plus repo, MMF, cash, BTC, gold, secured loans, equity stakes); Circle's reserves are pure US Treasury bills and repo (held in a BlackRock-managed 2a-7 money-market fund) plus cash at named US banks. Both issuers carry small excess reserves above circulating supply.

Major real-world stablecoin payment integrations: Visa and Mastercard cross-border merchant settlement; PayPal, Cash App, Robinhood consumer wallets; Stripe and Worldpay B2B payouts; Western Union and MoneyGram remittance corridors. The Cantor Fitzgerald entry surfaces Tether's primary US T-bill custodian connection, politically salient after Howard Lutnick's appointment as Commerce Secretary.

Global CBDC Tracker

Central bank digital currency status by country. China e-CNY leads by transaction volume and mandatory-acceptance footprint. The defining 2025 policy event is Trump EO 14178 (January 23, 2025) explicitly prohibiting a US retail CBDC, paired with the GENIUS Act framework for private US stablecoins, an explicit choice to let USDC, USDT, and PYUSD carry the dollar-on-rails role. EU and UK retail CBDC decisions are pending.
