Cboe Global Markets (CBOE) is one of the world's largest exchange holding companies, operating the largest options exchange in the U.S. (~30% market share). Its proprietary VIX and SPX options franchises are irreplaceable competitive assets.

• Exclusive SPX Listing Rights: Cboe holds exclusive U.S. listing rights for S&P 500 index options (SPX) through December 31, 2032 (non-exclusive through 2033), anchoring its highest-margin, most liquid derivatives franchise.
• Proprietary VIX Franchise: Sole owner of the VIX volatility methodology and its futures/options complex, making Cboe the de facto global benchmark for equity volatility — a brand and liquidity moat peers cannot replicate.
• 0DTE Options Leadership: Same-day-expiry (0DTE) SPX options hit a record 66.2% of total SPX volume in July 2026, a structural growth vector concentrated almost entirely on Cboe's platform.
• Diversified, High-Margin Revenue Base: Options, North American equities, Europe/APAC, global FX, and futures segments all posted Y/Y growth in Q2 2026, reducing reliance on any single geography or asset class.
• Fortress Balance Sheet: Net debt/EBITDA of roughly 0x gives flexibility for buybacks, dividends, and further international expansion.

• Record 0DTE and Mini-SPX Volumes (July 2026 volumes, reported 08/05/2026): Mini-SPX (XSP) options set a monthly ADV record of 238K contracts including a record 0DTE ADV of 138K contracts; multi-listed options ADV rose 28.4% Y/Y and index options ADV rose 34.0% Y/Y.
• Sell-Side Price Target Hikes (early August 2026): Following the Q2 beat, BofA raised its target to $330 (from $307) and Piper Sandler to $321 (from $295), citing higher 2026/2027 EPS estimates.
• Q2 2026 Earnings Beat & Guidance Raise (07/31/2026): Record net revenue of $731.6M (+25% Y/Y), adjusted diluted EPS of $3.56 (+45% Y/Y); management raised full-year 2026 organic net revenue growth guidance to the mid-to-high teens.

• ⚠️ SPX/Index Options Concentration: A large share of earnings flows through the SPX options franchise; any erosion of the S&P 500's benchmark status, or loss of listing exclusivity beyond 2032/2033, would be a structural threat to the moat.
• ⚠️ 0DTE Regulatory Scrutiny: Regulators continue to debate whether explosive growth in zero-days-to-expiry options (~66% of SPX volume) contributes to intraday "flash crash" risk; a regulatory cap or margin change could curb Cboe's fastest-growing revenue stream.
• ⚠️ European PFOF Ban: The EU's 2026 ban on payment-for-order-flow could disrupt retail liquidity that Cboe's European equities/derivatives business depends on.
• ⚠️ Volatility Dependence: Trading volumes and transaction revenue remain sensitive to swings in market volatility; a prolonged low-volatility regime could compress results.
• ⚠️ Valuation: Shares trade at ~25x trailing earnings, leaving less room for multiple expansion if growth decelerates.
