Circle Internet Group (NYSE: CRCL) shares plunged 17.55% in 24 hours, falling to $62. Meanwhile, shares of the American issuer of USDC, the second-largest dollar-denominated stablecoin, have suffered even heavier losses over the past 30 days, dropping by approximately 40.34%. The decline comes despite the company’s regulatory success in the EU.
Pressure came from two directions. First, during the annual Russell Index restructuring on June 26, 2026, the company was removed from five key growth indices. Second, a competing stablecoin, launched with the participation of some of Circle’s closest partners, entered the market. Let’s explore the rationale behind this move and what it could mean for investors.
What Happened to the Russell Indices?
Circle has been removed from several major growth indices in the Russell family, including the Russell 1000 Growth, Russell 3000 Growth, and Russell Midcap Growth. This was part of a scheduled annual rebalancing, a process in which the index provider revises the composition of index baskets based on formal criteria.
The significance of this event lies in the fact that these benchmarks are tracked by funds. Index funds and ETFs typically hold securities in the same proportions as the index. Therefore, when a company leaves an index, these funds may be forced to sell its shares in order to adjust their portfolios to the new basket. This creates additional supply in the market, regardless of the company’s fundamentals.
What Does This Mean for Investors?
The first consequence is likely to be a decline in passive holdings. Fewer index-linked funds will hold CRCL, reducing the company’s long-term passive investor base.
The second factor is liquidity risk. A reduction in the number of institutional holders could widen bid-ask spreads and increase volatility in the stock. Investors should monitor trading volumes, spread widths, and analyst target price revisions.
It is important to separate technical pressure from fundamental pressure. Part of the decline was likely caused by the rebalancing effect itself, but the initial news linked the 17.55% daily drop to a separate event: the launch of Open USD, a competing stablecoin from the Open Standard initiative. This means the technical selloff was compounded by rising competition in Circle’s core business.
Finally, it is worth considering the current valuation. CRCL is trading approximately 47% below the analyst consensus target, yet Simply Wall St considers the stock overvalued. Insider sales over the past three months also represent a significant risk signal.
Analyst View: A Blow From Within
Independent analyst Shanaka Anslem Perera argues that Circle’s decline is less about the emergence of a competitor itself and more about who is behind it. Open USD, launched with the participation of more than 140 companies, has been supported by some of Circle’s own key partners.
The project was endorsed by BlackRock, which manages approximately 80% of USDC reserves through the Circle Reserve Fund, and Coinbase, which co-founded USDC and receives approximately $908 million annually in distribution fees. Custodian bank BNY Mellon also joined the initiative.
The core issue lies in Circle’s business model. The company earns almost exclusively from interest on its reserves, which amount to approximately $74 billion in cash and short-term US government bonds. Open USD reverses this logic. Instead of the issuer keeping the interest income for itself, the new stablecoin shares almost all of its profits with the businesses that distribute it.
For distributors, the math changes. Instead of paying fees or relying on Circle’s distribution model, they may be able to capture the economics directly.
There is one important caveat. Open USD is being launched on Base, the blockchain owned by Coinbase, while Coinbase’s contract with Circle is up for renewal in August. This means Circle is heading into negotiations with a partner that has just helped bring an alternative stablecoin to market.
Perera also adds a caveat in favor of a more balanced valuation. What is happening could also be viewed as rational diversification. BlackRock is positioned to benefit from multiple avenues, while Open USD is expected to launch later this year.
USDC remains liquid, regulated, and in demand, with Circle’s CEO insisting that the market is large enough for several major players.
