Circle's IPO: How a Stablecoin Issuer Priced Itself Public

Circle Internet Group sold shares on the New York Stock Exchange on June 5, 2025, pricing at $31 — above an already-raised range — for a valuation near $7 billion, and closing its first day around $83 per share, a gain of roughly 168 percent, per Reuters and exchange data. It was the first major stablecoin issuer to list in the United States, and the debut turned an obscure payments-infrastructure company into the year's most-watched IPO window-opener. Honey Badgers covers listings as information, not investment advice.

What does Circle actually sell?

Circle's core product is USDC, the second-largest dollar-backed stablecoin, with a circulating supply in the tens of billions as of 2025. The documented business model, laid out in the company's S-1 filing, has an unusual shape: most of the revenue comes from interest on the reserve of Treasury bills backing the tokens — roughly $1.7 billion of total revenue in 2024, per the filing, almost all reserve income, of which the majority was shared with Coinbase under a distribution agreement. That makes Circle's revenue a levered play on interest rates: when the Federal Reserve cut rates in late 2024 and 2025, Circle's per-dollar income fell mechanically.

What did the S-1 disclose that mattered?

Three things. First, the Coinbase dependency: the distribution agreement pays Coinbase most of the reserve yield on USDC held on its platform, a term that surprised many readers of the filing. Second, the regulatory contingency: USDC's status depended on pending stablecoin legislation, which arrived weeks after the listing when the GENIUS Act was signed into law on July 18, 2025 — federal framework rather than state-by-state improvisation. Third, growth: USDC circulation roughly doubled year over year into 2025, from roughly $28 billion to over $60 billion, per company disclosures.

How did the pricing and pop actually go?

The company initially marketed at $24 to $26, raised the range, priced at $31, and watched the stock open near $69 and close the first day around $83. By late June the shares had touched $100-plus before settling; the float then behaved like the crypto-cycle proxy it is, swinging with bitcoin and with stablecoin headlines rather than with payments-peer comparables. An IPO pop of that size is standard underpricing dynamics at the extreme — money left on the table by sellers, captured by allocations — and it says more about scarcity of crypto equity exposure than about steady-state valuation.

What does the listing mean for the stablecoin market?

Circle's listing gave the stablecoin sector its first public financial statements, and the disclosures moved policy: legislators negotiating the GENIUS Act could price the reserve-disclosure and licensing requirements against a live public company rather than hypotheticals. The Act ultimately required issuers to hold high-quality liquid reserves and publish monthly attestations — close to what Circle already did, an alignment skeptics noted. For startups, the signal was simpler: the IPO window for fintech and crypto-adjacent companies, shut since 2021, was reopening.

What are the open questions on the record?

The rate dependency: every Fed cut compresses Circle's core revenue line, a risk the S-1 states plainly. The Coinbase share: the more USDC grows on Coinbase, the less Circle keeps. And competition: Tether, the larger rival, remains private and offshore with a reported treasury profit sharing no public statements; banks entering issuance post-GENIUS Act could compress fees further. Circle's answer on all three is transaction growth and new products — payments APIs and tokenized funds — where the record so far shows early traction, not proof.

Circle's debut worked as a listing: it priced, popped, and held a multi-billion public valuation through a rate-cutting cycle. Whether it works as a business is a question about interest rates and Coinbase's cut — and both are printed in the S-1 for anyone who reads past the ticker.
