Circle filed for an IPO, revealing USDC’s reserve-income engine

Circle Internet Group filed a registration statement for a proposed initial public offering with the U.S. Securities and Exchange Commission on April 1, 2025, opening the USDC issuer’s business model to public scrutiny. Circle also applied to list Class A shares on the New York Stock Exchange under the proposed ticker CRCL.

The filing was consequential because it offered a detailed, dated view of how a major dollar-denominated stablecoin business earned money, shared distribution economics and carried interest-rate exposure. It did not mean an offering had been completed: the April 1 prospectus left both the number of shares and the price range blank, and the registration statement had not yet become effective.

A stablecoin issuer built on reserve income

For the year ended December 31, 2024, Circle reported $1.676253 billion in revenue and reserve income from continuing operations, up 15.6% from $1.450466 billion in 2023. Reserve income contributed $1.661084 billion in 2024, or 99.1% of continuing-operations revenue. Net income from continuing operations moved in the opposite direction, falling to $156.991 million from $271.549 million over the same annual comparison.

Those figures defined Circle less as a conventional software subscription company than as a financial infrastructure business whose results depended heavily on income from the assets backing its stablecoins. Circle’s risk disclosures said lower interest rates reduce reserve return rates, while USDC circulation is the other primary driver of reserve income. The filing also cautioned that the relationship between rates and circulation was complex and unproven.

The cost side was equally important. Distribution and transaction costs reached $1.010811 billion in 2024, up 40.4% from $719.806 million in 2023. Circle attributed the increase principally to $216.6 million of additional distribution costs paid to Coinbase and $74.1 million of additional incentives tied to newer distribution partnerships, including an upfront one-time fee to Binance. These were Circle’s audited-period disclosures, not a forecast of 2025 economics.

What the filing said about USDC

Circle reported $43.9 billion of USDC in circulation and 4.3 million “meaningful wallets” as of December 31, 2024. The wallet measure was defined by Circle and should not be read as a count of unique people. The prospectus also stated that Circle held 24% of fiat-backed stablecoins in circulation at that date, using CoinMarketCap data. Coinburn did not independently reconstruct that market-share calculation.

The same $43.9 billion appeared as cash and cash equivalents segregated for stablecoin holders at year-end. That balance was a point-in-time accounting measure, not an April 1, 2025 market value, trading-volume figure or claim about USDC’s price on any exchange.

What remained unresolved on April 1

Circle’s announcement named J.P. Morgan and Citigroup as the lead active bookrunners, with other banks in supporting roles. But without a share count or price range, the event established intent and disclosure—not offering size, valuation, proceeds or investor demand. No CRCL market price existed on April 1 because the stock had not begun trading.

The strict event-day conclusion is therefore narrow. A leading stablecoin issuer took a formal step toward U.S. public markets and disclosed a profitable but concentrated model: reserve income dominated revenue, distribution costs were substantial, and both circulation and interest rates shaped results. Whether the SEC registration would become effective, what terms investors would accept and whether the offering would close remained future questions on April 1, 2025.
