Circle Surges Nearly 34% as Senate Passes Stablecoin Bill – But Is the Rally Sustainable?

On Wednesday, the U.S. Senate passed the so-called GENIUS Act (short for Guaranteed E-dollar and Nationally Integrated Ubiquitous Stablecoins) with a bipartisan vote of 68-30.

The news immediately set the crypto sector on fire. Circle ($CRCL) — widely seen as the “first stablecoin stock” — jumped nearly 34% in a single day, pushing its gains to more than 6x since going public just 10 days ago. Crypto exchange Coinbase ($COIN) rallied 16%, while Robinhood ($HOOD) rose 4%.

The bill proposes a federal regulatory framework for dollar-backed stablecoins, formally recognizing them as “digital cash.” That’s a major shift from their current informal role in crypto settlements.

While the bill still needs to pass the House and be signed by Trump (who has shown consistent support for crypto-friendly policies), optimism is running high. Bernstein analysts even projected that it could become law by late summer, calling it a historic opportunity to “bring stablecoin innovation back to U.S. soil.”

Circle CEO Jeremy Allaire called the Senate vote “history in the making” — and for good reason. If passed, the bill could pave the way for stablecoins to become part of mainstream payments, not just niche tools for crypto trading.

Circle Stock Soars — But ARK Is Cashing Out

Circle ($CRCL) went public on June 5 at $31 a share. Just 10 days later, it closed at $199.59 — a staggering 543% gain.

But while retail and institutional investors are clearly bullish, ARK Invest is taking some chips off the table. Cathie Wood’s firm sold a total of 643,000 shares over two days, locking in nearly $96.5 million, or about 14% of its initial stake.

ARK has long been known for its conviction in disruptive tech and crypto. Wood is also one of Bitcoin’s most vocal institutional advocates — earlier this year, she predicted BTC could reach $1.5 million by 2030.

So, is this just profit-taking, or a sign of caution about what’s next?

Interestingly, other major investors — such as BlackRock — haven’t reported similar moves. CEO Jeremy Allaire himself has only planned to sell around 8% of his personal holdings.

What’s Next?

This could mark a turning point for the U.S. crypto industry. For years, the lack of regulatory clarity has pushed stablecoin innovation abroad — particularly to Asia, where volume and adoption have surged. The GENIUS Act would change that, giving U.S.-based issuers like Circle a clearer legal path forward.

That said, markets may be getting ahead of themselves. The bill still has hurdles to clear, and even if passed, building out a compliant, scalable stablecoin ecosystem won’t happen overnight. Plus, the competitive landscape is intensifying, with players like PayPal and Tether also eyeing a role in the digital dollar space.

My Take

Circle’s explosive rally highlights just how hungry markets are for regulatory clarity. The GENIUS Act is arguably the most promising policy signal the U.S. crypto industry has seen in years. But a 500%+ run-up in 10 days — especially for a company that just started trading — feels frothy.

ARK’s move may not be bearish, but it’s a reminder that even true believers are managing risk. Regulatory wins are only the beginning. What really matters is execution — how well Circle can comply, scale, and become part of everyday payments in the real world.
