Why Circle Stock Crashed 17.55% Today?

Circle (CRCL) stock suffered one of its biggest single-day declines after dropping by 17.55% and wiping out nearly $3.6 billion in market value. While the sharp drop surprised many investors, it wasn’t caused by a single event. 

Two major reasons have put heavy pressure on the stock. Here’s what triggered the selloff.

Circle Removed From Multiple Russell Index

One of the biggest reasons behind today’s decline was Circle’s removal from five Russell Growth indexes, including the Russell 1000 Growth, Russell 3000 Growth, and Russell Midcap Growth.

The changes came during FTSE Russell’s latest annual index reconstitution, where companies are reclassified based on size and growth characteristics.

This change matters because many institutional investors and passive index funds automatically buy or sell stocks to match these indexes. Once Circle was removed, many funds likely reduced their positions, increasing selling pressure.

Data from Simply Wall St also shows CRCL shares had already fallen 32.8% over the past month, suggesting investors were preparing for the index rebalancing well before today’s decline.

OpenUSD Creates New Competition for USDC

The second factor putting pressure on Circle is the launch of OpenUSD (OUSD), a new dollar-backed stablecoin supported by more than 140 companies, including Visa, Ripple, Stripe, Coinbase, and BlackRock.

This OUSD stablecoin is a direct threat to the Circle revenue model. 

Unlike USDC, OpenUSD plans to share 100% of its reserve yield with its ecosystem partners. In comparison, Circle keeps 40% of the income generated from USDC reserves and distributes only 60%. 

This makes OpenUSD more attractive to partners because it offers a much higher share of the earnings.

Circle CEO Says USDC Still Has the Advantage

Circle CEO Jeremy Allaire responded to the competition by stating that stablecoins are largely a “winner-take-most” market.

According to Allaire, USDC’s biggest strength is not simply yield but its established network, regulatory position, and deep liquidity built over nearly a decade.

He even pointed out that USDC processed nearly $30 trillion in on-chain transactions during Q1 2026, representing roughly 80% of all dollar stablecoin transaction volume, while other dollar stablecoins accounted for the remaining 20%.

Circle believes the stablecoin market itself is still expanding rapidly, leaving room for multiple winners even as competition continues to intensify.
