Executive summary
According to data from Visa’s on-chain dashboard, USDC has reached a 70% share of adjusted stablecoin transaction volume in the first half of 2026, significantly outpacing USDT’s 25% share. This shift is primarily attributed to the adoption of USDC by major financial institutions, including Standard Chartered and BNY, which are increasingly utilizing Circle’s infrastructure for settlement and treasury management rather than developing proprietary stablecoin solutions.
The market views this as a validation of USDC’s compliance-first strategy. By positioning itself as the preferred rail for regulated entities, Circle has successfully captured the "institutional-grade" narrative. This adoption is not merely branding; it represents a tangible integration into the legacy financial stack, providing a liquidity moat that is difficult for decentralized or less-regulated alternatives to replicate in the short term.
Why it matters
The economic impact of this shift centers on the sustainability of Circle’s revenue model. While the 70% volume dominance strengthens USDC’s network effects, it has simultaneously invited competitive pressure. The recent launch of OpenUSD—a consortium-backed stablecoin supported by Stripe, Visa, Mastercard, Coinbase, and BlackRock—has introduced a "race to the bottom" regarding minting and redemption fees.
From a market-structure perspective, this creates a bifurcation. USDC currently benefits from established liquidity and institutional trust, which keeps its peg stable and its utility high for cross-border settlements. However, the 20% drop in Circle’s valuation (as reported by Bankless) following the OpenUSD announcement suggests that investors are pricing in a long-term margin compression. The real-world utility of USDC is growing, but its ability to extract rent from that utility is under threat. Investors should monitor whether the "institutional moat" is sufficient to offset the fee-free pressure from OpenUSD, as this will determine whether USDC remains a high-margin business or becomes a commoditized public utility.

Bottom line
USDC currently holds a dominant 70% share of stablecoin volume, driven by deep integration with traditional banking partners. While this secures its position as the institutional standard, the launch of OpenUSD introduces significant margin risk. The most likely scenario is a period of continued dominance for USDC, accompanied by a long-term decline in fee-based revenue as the market shifts toward lower-cost alternatives. The biggest risk is a rapid migration of institutional liquidity to OpenUSD, which would invalidate the current thesis of USDC's unassailable moat. Investors should focus on volume trends and the rate of adoption for OpenUSD over the next 90 days.

The CEO of the Solana Policy Institute indicates a mere 10% chance of the CLARITY Act passing before the November midterm elections, citing congressional gridlock and objections from traditional financial institutions.

Stablecoins Dominate Crypto Card Spend: A Shift in Utility, Not a Capital Inflow Catalyst?
Dollar-backed stablecoins, primarily USDC and USDT, have captured 84% of crypto card spending, reversing a trend previously dominated by euro tokens. This reflects a structural shift in stablecoin utility and reinforces the dollar's role in crypto payments, though its immediate impact on overall crypto market liquidity or asset prices is assessed as limited.

Market concerns regarding Open USD (OUSD) as a direct threat to USDC have softened following statements from Coinbase, Visa, and Mastercard confirming a multi-stablecoin approach.
