Key terms

$33 trillion stablecoin volume (2025)

Total measured stablecoin transaction volume in 2025 per Bloomberg reporting — up about 72% year over year. Wider on-chain trackers placed the figure as high as $46T versus roughly $7.4T in 2022.

USDC vs. USDT volume split (2025)

USDC processed about $18.3T in 2025 transaction volume versus USDT’s roughly $13.3T, even though USDT remains larger by market cap (~$175-186B vs. USDC’s ~$73-77B in Q3 2025).

USDT + USDC dominance

Combined, USDT and USDC make up roughly 85-93% of total stablecoin market capitalization. Everything else (USDS, USDe, PYUSD, FDUSD, GHO, crvUSD, EURC) shares the remainder.

Stablecoins as 30% of on-chain volume

Stablecoins now account for roughly 30% of all on-chain crypto transaction volume across major chains, up from closer to 10% three years earlier.

B2B stablecoin payments

Cross-border business-to-business stablecoin volume reached about $400B annualized by late 2025 and represents roughly 60% of identified non-trading stablecoin payments.

Stripe / Bridge acquisition

Stripe acquired stablecoin payments orchestrator Bridge for approximately $1.1 billion in October 2024 — the largest signal that mainstream payments now treat stablecoins as core infrastructure.

Africa stablecoin adoption

Sub-Saharan Africa received more than $205B in on-chain value during 2024-2025, with stablecoins about 43% of regional volume. BVNK’s 2026 survey reports about 79% of African crypto users hold stablecoins.

Mercy Corps Kenya pilot

A Mercy Corps Ventures stablecoin remittance pilot in Kenya that reduced the effective cost of moving money home from approximately 29% to about 2% of the transferred amount.

Argentina crypto adoption

Argentina recorded approximately $91.1B in crypto transfers in 2024, with 61.8% in stablecoins (versus 44.7% globally) and roughly 19.8% of the population owning crypto.

Venezuela stablecoin dominance

By 2025, USDT alone accounted for roughly 91% of all crypto transactions in Venezuela. Over an 8-month stretch the bolivar lost 70%+ of its value, accelerating the move into USDT-denominated balances.

USDe peak and current size

Ethena’s synthetic delta-neutral USDe launched February 2024, peaked near $14.6B in late 2025, and now sits around $4.7-9B. It was the fastest stablecoin in history to reach $10B, doing so in about 500 days.

PYUSD multi-chain growth

PayPal USD totals about $733M in 2026, with the Solana version (~$377M) now larger than the Ethereum version (~$356M). PYUSD expanded to Stellar in 2025 and onto Arbitrum.

Tether profit and reserves

Tether reported about $13B in net profit in 2024 and $10B+ year-to-date through Q3 2025. Reserves include $135B+ in U.S. Treasuries, about $17.4B in gold (over 132 metric tons), $9.9B in Bitcoin, and ~$6.8B in excess reserves.

USAT (US-regulated Tether)

Tether’s GENIUS Act-compliant U.S. stablecoin, launched in 2025 alongside the existing offshore USDT. USAT meets U.S. licensing and disclosure requirements while USDT continues to serve global markets.

GENIUS Act compliance buckets

Post-GENIUS, U.S. stablecoin issuers split into compliant U.S.-licensed (Circle, Paxos), grandfathered/transition issuers, and offshore issuers facing restrictions on direct U.S. retail distribution.

MiCA-driven USDT delisting

After MiCA stablecoin rules took effect June 30, 2024, USDT was effectively delisted from EU-regulated exchanges that had not obtained MiCA authorization. USDC and EURC dominate European on-chain dollar/euro flows.
