Market Share and Volume Comparison
Published 7/7/2026, 9:21:10 AM
Based on market data as of July 7, 2026, USDC is not closing the gap on Tether (USDT) in absolute terms. While USDC has achieved a slightly higher percentage growth rate over the past year, the absolute dollar-denominated lead held by USDT has reached an all-time high.
Market Share and Volume Comparison
Tether remains the dominant stablecoin by a significant margin. As of the current research data, USDT's market capitalization is more than double that of USDC.
| Metric | Tether (USDT) | USD Coin (USDC) | Difference (Gap) |
|---|---|---|---|
| Market Cap | ~$184.17 Billion | ~$73.17 Billion | $111.00 Billion |
| 1-Year Growth | 15.56% | 18.75% | +3.19% (USDC lead) |
| USDC/USDT Ratio | — | 0.397 | — |
Analysis of the "Gap"
The "gap" between the two stablecoins is widening despite USDC's faster relative growth. Because USDT starts from a much larger base, its 15.56% growth added more total liquidity to the market than USDC's 18.75% growth.
- Absolute Gap Expansion: The dollar lead held by USDT has increased from approximately $96 billion one year ago to $111 billion today.
- Liquidity Dominance: USDT continues to dominate offshore exchanges and perpetual trading pairs, while USDC maintains a strong but secondary position, primarily within regulated U.S. channels and specific DeFi protocols.
Conclusion
USDC is not closing the gap in any meaningful way that threatens USDT's dominance. While USDC grew ~3% faster than USDT over the last 365 days, the absolute market cap difference has widened by approximately $15 billion. USDT remains the "liquidity king" of the crypto ecosystem as of July 2026.
