Circle Internet Financial reported second-quarter 2026 results with $701 million in total revenue and reserve income, up 7% year over year, while quarter-end USDC in circulation reached $73.3 billion (+19% YoY). The print is a float-and-rates story first: reserve income rose only 5% even as average USDC circulation grew 25%, because the reserve return rate fell 66 basis points.
Net income from continuing operations printed at $48 million, a $530 million swing from the year-ago quarter. That jump is mostly the hangover from IPO-era stock-based compensation fading, not a sudden jump in stablecoin unit economics. Bitcoin traded near $64,459 (+0.2% 24h) and Ether near $1,895 (+1.3% 24h) on our CoinGecko-derived market snapshot at .
Arc’s founding-validator list and the federal trust charter sit in the same release. They matter for the next chapter of Circle’s story. They do not rewrite what this quarter’s P&L actually said about USDC float versus yield.
What happened
Circle’s Q2 2026 pressroom release (Tier B primary, read 2026-08-06) put the operating picture in plain numbers:
- USDC in circulation: $73.3 billion at quarter end (+19% YoY).
- USDC onchain transaction volume: $14.8 trillion in the quarter (+151% YoY).
- Total revenue and reserve income: $701 million (+7% YoY).
- Reserve income: $668 million (+5% YoY), with average USDC circulation up 25% and the reserve return rate down 66 bps.
- Other revenue (subscription and services): $34 million (+41% YoY).
- Adjusted EBITDA: $143 million (+8% YoY).
- Net income from continuing operations: $48 million (up $530 million YoY on lower stock-based compensation after the Q2 2025 IPO).
Distribution, transaction, and other costs were $412 million (+1% YoY). GAAP operating expenses fell 56% to $254 million on that same stock-comp base effect, while adjusted operating expenses rose 23% to $146 million as Circle kept spending on product, infrastructure, and AI.
The same release repeated the Arc founding-validator cohort (BlackRock, DTCC, Visa, Mastercard, and others) ahead of a September 16 public mainnet target on Arc, plus OCC approval for Circle National Trust and NYDFS approval for Circle New York Trust. We already covered the validator list in depth in our Arc founding-validators reaction. Today’s job is the earnings math, not a second pass on the validator roll call.
Secondary coverage tracked the same figures. The Block framed the $701 million revenue line alongside the Arc validator names. Useful confirmation. Not the lead.
Context
USDC is still a stablecoin float business wearing a software coat. Most of Circle’s top line is reserve income earned on cash and cash-like assets backing tokens in circulation. When average float rises 25% and reserve income only rises 5%, the missing piece is yield: that 66 bps drop in the reserve return rate is doing real work against the growth in tokens outstanding.
That is the same family of pressure we watched when Tether’s Q2 attestation showed a thinner excess-reserve cushion even as the issuer stayed profitable. Different balance-sheet style, same macro channel: lower short rates and a quieter crypto tape squeeze the easy float years.
Circle’s non-reserve line is growing faster in percentage terms ($34 million other revenue, +41% YoY), and Circle Payments Network (CPN) hit $14.7 billion in annualized trailing-30-day volume at quarter end (+76% QoQ) with 175 financial institutions enrolled (+29% QoQ). Those are real rails. They are still small next to $668 million of reserve income. Product is not yet the P&L center of gravity.
The trust-bank and NYDFS trust approvals sit in the custody and reserve-management lane. OCC’s Circle National Trust charter authorizes federally regulated digital-asset custody and leaves room for future USDC Reserve management under that charter. That is a structural upgrade for how Circle can hold and supervise reserve assets over time. It does not, by itself, fix a thinner reserve return rate in Q2.
On the tape, Bitcoin’s calm range near $64k and Ether’s mild bounce near $1.9k (snapshot ) match Jeremy Allaire’s own framing in the release: a slower crypto market and a softer rate backdrop sit outside Circle’s network controls.

Our read
Stance: Circle’s Q2 is a healthy float business under rate pressure, not a breakout software quarter. The $48 million net income headline is mostly base-effect optics from lower IPO stock compensation. The honest tell is reserve income up only 5% against 25% average USDC circulation growth and a 66 bps yield cut. Arc validators and the national trust charter are strategic. They are not what paid this quarter’s bills.
I care about stablecoin issuers when they show you the float, the yield, and the distribution cost with equal honesty. Circle did that. Distribution costs barely budged (+1%), which suggests partner payouts are not exploding even as circulation grows. Adjusted opex is rising (+23%) as Circle builds Arc, Agent Stack, and trust infrastructure. That spend is a choice. The yield compression is not.
Narrative is cheap here. Exit liquidity for the stock story will keep chasing Arc mainnet and bank charters. Exit liquidity for the USDC system still lives in redeemability, reserve quality, and whether circulation can outrun falling reserve yields. On that last point, Q2 says circulation is winning the volume race and barely winning the income race.
Falsifiable claim: Our read is wrong if, in Circle’s next quarterly results release on or before 2026-11-15 UTC, reported reserve income rises year over year and other revenue is at least 15% of total revenue and reserve income. That mix shift would mean subscription and services have already taken a meaningful share of the top line, and this quarter’s “float-plus-rates” frame would be stale.
What to watch
- Reserve return rate vs average USDC circulation in the next print. If float growth stays mid-teens or better while the return rate keeps sliding, reserve income can stall even with a bigger USDC footprint.
- September 16 Arc public mainnet and whether named founding validators show up as live operators in a primary Circle or Arc update (we already set a related check in the Arc validators piece).
- CPN scale: can annualized volume and enrolled institutions keep compounding from the $14.7 billion / 175 FI marks without a jump in distribution costs that eats the other-revenue gains?
- Trust-charter follow-through: any primary update that Circle National Trust is actually managing a slice of the USDC Reserve, not only holding a custody permission.
Circle is still the regulated USDC issuer the market watches when dollar-token float meets policy rates. Q2 kept that identity intact. The product stack got louder. The P&L stayed honest about yield.
