Circle Internet Sinks 8% as ARK Trims Its Stake Before the Senate Clarity Act Vote; Coinbase and Bitmine Drop 5%

ARK Invest singled out one crypto stock for its heaviest selling of the session, and the Senate vote looming today could either rescue it or accelerate the slide for reasons that have nothing to do with the broader market.

Circle Internet Group (NYSE:CRCL | CRCL Price Prediction) stock is falling on Tuesday after ARK Invest trimmed its position ahead of a U.S. Senate procedural vote on the Digital Asset Market Clarity Act. Circle Internet stock is down 8% to $89.56 in midday trading. The move stands out among crypto-linked equities because the same manager cut several crypto positions but concentrated the sale in Circle Internet.

Coinbase Global (NASDAQ:COIN) shares are down 5% to $181.06. Also lower, Bitmine Immersion Technologies (NYSEAMERICAN:BMNR) stock is sliding 5% to $24.38. Meanwhile, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.5% to $757.09, so the selling is concentrated in crypto-linked names.

For broader crypto context, the iShares Bitcoin Trust ETF (NASDAQ:IBIT) is down 3% to $43.26. Circle Internet stock is still up 25% over the past month, so today’s decline gives back part of a run rather than breaking new ground.

ARK Trim Concentrates the Damage

ARK Invest disclosed selling 113,369 Circle Internet shares on Monday through the ARK Innovation ETF (NYSEARCA:ARKK) and another 28,981 Circle Internet shares through the ARK Next Generation Internet ETF (NYSEARCA:ARKW). Circle Internet was the largest dollar-weighted crypto-related sale in the ARK Innovation ETF that session. ARK Invest also pared nearly every other crypto-linked position it holds, including its Coinbase and Bitmine stakes.

The concentration is what separates Circle Internet from the rest of the group today. Circle Internet is falling roughly half again as hard as Coinbase and Bitmine, and the ARK Invest trim is the piece the others don’t carry. The same manager cut all three names, but the heaviest hand landed on Circle Internet.

Clarity Act Vote Cuts Both Ways

The Senate is holding a procedural vote today on the Clarity Act, and the pending framework cuts both ways for Circle Internet. Legislation that legitimizes stablecoins also clears a path for bank-issued competitors with cheaper funding and established customer bases. That’s why Circle Internet is trading heavier than peers even before the outcome is known.

The bull case for Circle Internet argues that regulatory clarity is worth more to a regulated stablecoin issuer than to anyone else in the complex. The bear case flags that today’s vote is procedural rather than final, so the uncertainty around Circle Internet doesn’t end whichever way the count lands. Coinbase and Bitmine face the same overhang without the same idiosyncratic supply pressure from a high-profile institutional seller.

What to Watch Next

Circle Internet’s near-term direction hinges on the vote’s outcome and on whether ARK Invest disclosures later this week extend the trim. Investors can watch for signs that Coinbase and Bitmine stabilize first if the Clarity Act clears its procedural hurdle, since Circle Internet has more overhang left to work through. The S&P 500 is down only modestly, so today’s pain sits with crypto-linked equities while the broad market holds up.

Sizing your exposure to Circle Internet against Coinbase and Bitmine may matter more than trying to call the Senate (we wrote a free playbook on keeping speculative bets to 5% of a portfolio, with the sizing and exit rules, here: Small Stakes, Big Swings). Circle Internet stock is still up sharply over the past month, which leaves room for further mean reversion if institutional selling continues into the close.
