CME Group Q3 2026 Earnings: Record $1.74B Revenue on 29.4M Contracts a Day

On October 21, 2026, CME Group reported the highest third-quarter revenue in its history — $1,737.3 million, up 13% — on record average daily volume of 29.4 million contracts. Net income rose 14% to $1,036.9 million, diluted EPS rose 16% to $2.89, and the company returned nearly $1 billion to shareholders in a single quarter. The twist is where the money sits: $155 billion of the $192 billion balance sheet is not CME's money at all, but clearing-member collateral passing through. This post walks the quarter line by line, in a ledger you can audit.

The Headline Numbers​

Every figure below comes from the Form 10-Q and the earnings release. The quarter ended September 30, 2026:

Read it top to bottom and the quarter is operating leverage doing its thing: revenue up 13%, expenses up just 5.5%, operating income up 17%. Below the operating line the story is flatter — non-operating income of $213.4 million grew only 4%, because the interest CME earns reinvesting clearing collateral fell with the Fed funds rate, and the effective tax rate ticked up to 23.5% from 22.9%. That is why net income (+14.2%) trails operating income (+17.4%), and why EPS (+16.1%) beats net income only through a shrinking share count. Nothing here is low quality; it is just a quarter where the core franchise outperformed the rate-driven float business sitting underneath it.

The GAAP-to-adjusted bridge is small and clean: $47 million separates reported net income ($1,036.9M) from adjusted ($1,083.9M), dominated by the $56 million amortization of purchased intangibles plus $4 million of S&P Dow Jones Indices and FanDuel Prediction Markets amortization flowing through equity earnings, net of tax. Adjusted diluted EPS of $3.02 is 4.5% above GAAP $2.89 — a routine add-back quarter, not a sculpted one.

Revenue Deep Dive: The Toll Booth at Full Volume​

CME sells three things — trade execution, market data, and everything else — and all three grew:

Clearing and transaction fees are 79% of revenue, and the quarter was a volume story, not a pricing story. "As uncertainty intensified in Q3, clients turned to CME Group in record numbers to manage risk and capitalize on opportunities," Chairman and CEO Terry Duffy said in the release — the robust-demand signal, stated plainly. ADV hit 29.4 million contracts, the highest Q3 on record, with "double-digit volume growth across all six asset classes," and the average rate per contract printed at $0.679. When every asset class grows double digits at a flat-ish capture rate, the top line is a pure function of fear, and Q3 had plenty.

Market data is the smaller line doing the heavier compounding: a record $243 million, up 20%, growing half again as fast as transaction fees. Data revenue recurs without clearing a single contract, so every quarter it outgrows the toll line, the franchise gets a little less cyclical. Non-U.S. ADV reaching "a third-quarter high of 9 million contracts" is the market-expansion signal — nearly a third of volume now originates outside the United States, and the release pairs it with a product-ramp note ("We launched several innovative new products") and an access pitch: cloud migration progress makes CME "the only exchange to offer clients the choice of both co-location and cloud-managed services to expand access to our markets for years to come."

The margin story starts here too: compensation — the largest expense line at $234.3 million — actually fell 1.4% year over year while revenue grew 13%. Headcount leverage on a volume surge is the whole exchange thesis, and the quarter exhibits it.

The Margin Story: 66% Operating Margin, Still Expanding​

Operating margin expanded 2.4 points year over year, to 65.7% — two dollars of every three in revenue reaching operating income. The mechanics are all in the expense lines: compensation down 1.4% on 13% revenue growth, technology up 13% (the Google Cloud migration the release touts is not free — and the release's own risk factors warn about "duplicative costs of maintaining both on-premise and Google Cloud environments during the transition"), and professional fees down 15%. The one cost line running hotter than revenue is licensing and other fee agreements, up 28% to $104.2 million — the index-license toll (S&P and friends) growing faster than the toll CME itself collects. At 6% of revenue it is a footnote, not a threat, but it is the only expense line with a structurally adversarial counterparty.

Net margin barely budged — 59.7% versus 59.1% — because the float business shrank underneath the franchise. Investment income fell 8.4% to $1,418.1 million as the Fed funds rate came down, and while the offsetting distribution to clearing firms fell 9.5% to $1,264.0 million, the retained spread was roughly flat. Add a 0.6-point higher tax rate and the 17% operating-income growth compresses to 14% at the net line. FY2025's gaudy 62.5% net margin, for reference, flattered itself with a $903 million collateral spread in a higher-rate year — the comparison that makes this quarter's flat spread look like a headwind rather than gravity.

The One Big Question: Who Owns the $155 Billion?​

Open the balance sheet and the first thing you notice is that CME Group barely owns its own balance sheet. Performance bonds and guaranty fund contributions — cash and securities clearing members post as collateral — stand at $155,179.7 million on both sides, 81% of total assets:

The mechanics: CME reinvests the cash collateral, keeps the earnings, and passes most of the interest back to the clearing firms. The 10-Q's MD&A breaks the quarter into $1,391.7 million of reinvestment earnings against $1,269.0 million of distribution expense, and attributes both declines "to a lower Federal Funds rate compared with the same period in 2025." The spread CME keeps — $154 million this quarter, $903 million last year — is therefore a levered bet on short rates sitting inside an exchange stock. FY2024's spread was just $420 million; FY2025's was $903 million; the difference is almost entirely the rate path, not anything CME did.

This reframes the whole quarter. Strip the $213 million of non-operating income and CME is a $1.14 billion-operating-income toll booth worth owning at almost any multiple; include it and every Fed meeting moves earnings by tens of millions. The bull case is that rates stay high enough to keep the spread near $150 million a quarter. The bear case is that the spread has already halved from its run-rate — annualized, Q3's $154 million is $617 million against FY2025's $903 million — and the balance sheet gives no hedge: the $155 billion earns what the Fed says it earns. Watch the spread, not the ADV; volume is the story management tells, but rates are the story the income statement keeps.

Tracking a $192 Billion Balance Sheet in Plain Text​

An exchange is the ideal subject for double-entry modeling: every dollar of collateral is simultaneously an asset CME holds and a liability it owes, and Beancount forces both legs to reconcile. Read how we model every company for the conventions; here is CME's Q3 exactly as filed, in millions:

Income posts negative (credit), expenses positive (debit), and the transaction sums to zero. The balance-sheet number that tells the CME story is the performance-bonds pair itself: $155,179.7 million on both sides, the member collateral the spread economics above rent out. Behind it sits the quieter compounding machine — intangible trading products at $17,175.3 million, unchanged to the dollar across every period in the ledger, the indefinite-lived right to be the venue. And the capital structure keeps shrinking around it: 357.4 million shares outstanding, down from 359.0 million at year-end even after the March conversion of all 4.6 million Series G preferred shares into common, because the $3 billion buyback (now $1.0 billion remaining) retires stock faster than conversion creates it.

The Multi-Year Arc: The Float Giveth, the Toll Booth Keepeth​

This ledger opens at FY2024 with two audited annuals and the latest quarter — the full span:

Two engines, two tempos. The toll booth compounds steadily: revenue up 6.4% in FY2025 and running 9.3% ahead through nine months ($5,323.6M vs $4,871.9M), market data compounding double-digits (13% in FY2025, 19% through nine months), expenses growing slower than revenue. The float engine is a rate call: the retained spread more than doubled from $420 million to $903 million in FY2025, then sagged back toward a $617 million annualized pace in Q3. Net income's 15.5% FY2025 growth was more than half spread; the 9M 2026 growth of 11.9% ($3,233.0M vs $2,889.3M) is mostly toll booth. That rotation — from rate windfall to volume compounding — is the healthiest thing in this table, and it is why the quarter reads strong even as the float fades.

The shareholder-return arc matches: nine-month operating cash flow of $3,292.9 million funded $3,637.7 million in dividends and $1,770.4 million in buybacks, with the difference drawn from a cash balance that fell from $4,416.9 million to $2,198.5 million. Returning 164% of operating cash flow is affordable exactly once — it is a verdict on how much cash the franchise mints, not a run rate.

The Verdict: Bull vs. Bear​

Bull Case

• Record 29.4M ADV with double-digit growth across all six asset classes — volatility demand is broad, not a single-product spike, and non-U.S. ADV hit a record 9M.
• 65.7% operating margin, expanding 2.4 points, with compensation down 1.4% on 13% revenue growth — textbook exchange operating leverage.
• Market data at a record $243M, +20%, growing 1.6x the toll line — the recurring, acyclical diversifier keeps compounding.
• $999.4M returned in one quarter ($465.9M dividends + $533.5M buybacks) with $1.0B of authorization left — the payout is the thesis, and it is covered by the toll booth alone.
• Series G overhang gone: all 4.6M preferred shares converted March 5, 2026, so every dollar of net income is now common-shareholder income — GAAP EPS needs no two-class haircut anymore.

Bear Case

• The $154M quarterly spread annualizes to $617M against FY2025's $903M — the float is fading with rates, and investment income already fell 8.4% YoY; the numbers do not yet support "robust" non-operating demand of any kind.
• Nine-month returns of $5.4B against $3.3B of operating cash flow drew cash down $2.2B — repeat that twice more and the buyback is funded by the revolver, not the franchise.
• Licensing costs up 28% — the S&P toll grows faster than CME's own toll, and it is the one cost line CME cannot negotiate by coding harder.
• Clearing fees are 79% of revenue at a $0.679 blended capture rate — a calm-volatility quarter reverses the entire volume story, and management's "uncertainty intensified" cuts both ways.
• Adjusted EPS ($3.02) exceeds GAAP ($2.89) by adding back real amortization on real acquired intangibles — $60M a quarter of intangibles that someone paid real money for, excluded forever.

Our Take: Own the toll booth, rent the float. The volume franchise just printed its best Q3 ever at a 66% operating margin with costs barely moving, and that alone justifies the multiple — but $154 million of the quarter's earnings rides a rate spread that has already peaked, and the payout now exceeds operating cash flow. As long as uncertainty keeps clients hedging in record numbers, the toll booth covers the float's fade; the quarter to fear is the quiet one, when volume normalizes and the spread keeps falling. This was not that quarter.
