Cboe Global Markets delivered another beat-and-raise quarter, but the more important story is that it is now growing earnings faster than revenue. Adjusted EPS of $3.63 topped the $3.43 consensus by 4.0% and the $3.49 Earnings Whisper number, and rose 36.0% from a year ago. Management raised its 2026 organic net revenue growth target to 'high teens', the third straight quarterly increase, and lowered adjusted operating expense guidance to $830 to $845 million. That combination of higher revenue expectations and lower costs carried the quarter. Underneath it, though, top-line growth is clearly slowing.

The headline figures need some care. Reported revenue of $1.359 billion grew 19.0% and appears to exceed consensus by 93.4%. That surprise reflects a mismatch: the reported figure is gross total revenue, while the $702.54 million consensus tracks net revenue. Net revenue, the metric Cboe manages to, was $712.2 million, up 18% and only modestly ahead of the estimate. Gross revenue was also inflated by regulatory fees, which jumped to $155.5 million from $11.8 million and are largely offset in cost of revenues. GAAP EPS of $4.08 was flattered by a $71.5 million non-taxable gain on the sale of Cboe Australia. That gain was partly offset by a $14 million reserve on Consolidated Audit Trail notes receivable and $16.7 million of realignment costs. The adjusted figure is the cleaner read, and it is still strong. Adjusted operating expenses fell 3% to $204 million, and adjusted operating margin widened 6.1 points to 71.4%. A lower adjusted tax rate of 27.6%, versus 30.4% a year ago, added to the result.

The central tension is deceleration. Net revenue growth eased to 18% from 25% in the second quarter and 29% in the first, and net revenue fell sequentially from a record $732 million. Derivatives growth slowed to 22% from 30% and 32% in the two prior quarters. Cash and spot growth fell to 12% from 22% and 34%. Futures revenue declined 5%, and VIX options volume grew only 3% in a low-volatility tape. Several share metrics also slipped:

• U.S. on-exchange equities share fell to 8.9% from 9.8%.
• European equities share dropped to 23.0% from 25.4%.
• Multi-listed options revenue per contract fell to $0.052 from $0.064 in the second quarter.

The franchise core remains powerful, however. Index options volume rose 24% to 6.1 million contracts a day, and zero-day options reached a record 65% of SPX volume. Data Vantage posted record net revenue, up 13%, or roughly 16% excluding Australia. Its growth target was raised to 'mid teens'. Management's tone has shifted from last year's restructuring narrative toward a growth framing.

The strategic catalysts are substantial:

• The exclusive S&P license is extended through 2051, removing a long-standing overhang on SPX and VIX.
• SEC approval for company-KPI event contracts supports a November launch, with Robinhood as launch partner.
• Single-stock options now trade in extended hours, where Cboe captured 63% of morning volume and 91% of curb volume.
• The board added $550 million to the buyback authorization, lifting capacity to roughly $1 billion.
• Management said VIX activity rebounded early in the fourth quarter.

Bears still have legitimate ammunition. The S&P deal brings a royalty step-up in 2027 that depends on SPX price increases, which could weigh on volumes. KPI fees are waived through 2026, so the new contracts add no near-term revenue. Competition there is crowding, with filings from NYSE, Nasdaq and MEMX, rivalry from Kalshi and Polymarket, and unclear regulatory jurisdiction. Management also flagged AI-driven technology cost inflation as a pressure on spending.

Investor sentiment improved meaningfully into the report, swinging from -0.38 after the July release to +0.11. Shares closed at $314.25 the day before earnings, up 9.3% from the opening price after the prior report and 7.6% above the 200-day moving average. The ride was volatile. The stock fell to a quarterly low of $252.82 on September 28, rallied to $341.27 on October 23, and then gave back 7.9% before the report. Most Earnings Whispers trend signals are positive, while sequential growth is neutral, consistent with slowing revenue momentum.

The bottom line is that Cboe executed well: it beat, raised guidance again, cut costs and secured its most important franchise for 25 years. But the earnings story is increasingly carried by margins and buybacks rather than accelerating volume growth. The fourth quarter will test whether returning volatility and new products can stabilize the top line.
