Overview
Cboe Global Markets operates options, equities, futures, clearing, data, and institutional FX venues; Options supplied 64.8% of Q2 2026 net revenue and 71.0% of positive segment operating income. Its strongest barriers are the exclusive SPX license through 2032, proprietary VIX methodology, and liquidity networks around benchmark derivatives. Cboe Clear Europe adds a narrower clearing rail, while cash-equity and FX networks are contested and price sensitive. Q2 shares were 30.0% in U.S. options, 9.4% in U.S. exchange equities, and 24.4% in European equities. License renewal, substitute hedges, regulation, outages, and fee competition are central risks; pending Canada and Australia sales narrow the footprint.

Moat Claims
Options
U.S. listed options exchanges (multi-listed + proprietary index options)
Q2 2026 net revenue was $473.9m of $731.6m. Segment operating income was $341.0m; operating_profit_share uses $480.3m, the sum of positive reported segment operating income before $4.3m of corporate items and eliminations.
Contractual Exclusivity
Legal
Contractual Exclusivity
Strength
Durability
Confidence
Evidence
Cboe's exclusive U.S. S&P 500 index-options right runs through December 31, 2032. SPX is a flagship revenue product that rival U.S. exchanges cannot list directly, creating a strong but contract-expiry-dependent barrier.
Contractual Exclusivity moat: definition, examples, and stocks
Erosion risks
- Index provider renegotiation or non-renewal at expiry
- Regulatory constraints on index options (e.g., 0DTE rule changes)
- Volume migration to futures/OTC substitutes in some hedging use-cases
Leading indicators
- SPX options ADV and revenue per contract
- Renewal/extension announcements for index licensing
- Competitor launches of close substitutes (ETF options, futures products)
Counterarguments
- Customers can hedge with CME equity index futures/options or ETF options without SPX
- If licensing terms worsen, economics (not just volumes) could compress materially
Two Sided Network
Network
Two Sided Network
Strength
Durability
Confidence
Evidence
Cboe's 30.0% U.S. options share and growing index volume support a liquidity loop between customer flow and market makers. The effect is strongest in exclusive SPX/VIX products; multi-listed options remain portable and fee sensitive.
Two Sided Network moat: definition, examples, and stocks
Erosion risks
- Fee/rebate competition shifting liquidity across options venues
- Market maker concentration and reduced competition in liquidity provision
- Regulatory changes to retail routing/PFOF impacting displayed liquidity
Leading indicators
- Cboe options market share
- Bid/ask spreads and depth in flagship options (SPX, VIX options)
- Number/concentration of active market makers
Counterarguments
- Multi-homing is common; order flow is price-sensitive and can move quickly
- Exchange economics are constrained by competitive rebates and routing incentives
North American Equities
U.S. and Canadian equities trading venues (exchanges + ATS) and related market data/access services
Q2 2026 net revenue was $114.7m of $731.6m. Segment operating income was $66.1m; operating_profit_share uses the $480.3m positive-segment denominator described in Options. Cboe Canada remains included because its separately closing sale to TMX was pending at June 30.
Two Sided Network
Network
Two Sided Network
Strength
Durability
Confidence
Evidence
Cboe has a modest, contested liquidity network across four U.S. exchanges and BIDS: order flow attracts liquidity and execution opportunities, which can attract more flow. Q2 exchange share fell to 9.4%, while off-exchange BIDS share rose to 18.8%, so the evidence supports a meaningful venue position but not a strong or uniform network moat.
Two Sided Network moat: definition, examples, and stocks
Erosion risks
- Fee and rebate changes move order flow to competing exchanges or wholesalers
- Brokers internalize more flow or favor alternative block venues
- The pending Cboe Canada disposal reduces segment breadth
Leading indicators
- U.S. exchange and BIDS off-exchange market shares
- Matched volume, net capture, and liquidity-payment intensity
- Customer and liquidity-provider concentration
Counterarguments
- Broker routing is multi-venue, automated, and highly price sensitive
- National exchange registration and fast technology are replicable by well-funded peers
Europe and Asia Pacific
European equities & listed derivatives trading venues and clearing (plus Australia and Japan equities venues)
Q2 2026 net revenue was $84.8m of $731.6m. Segment operating income was $41.6m; operating_profit_share uses the $480.3m positive-segment denominator. CEDX closed in February; Australia remained included as held for sale, with closing expected in Q3 2026 subject to approvals.
Clearing Settlement
Network
Clearing Settlement
Strength
Durability
Confidence
Evidence
Cboe Clear Europe is an established pan-European central counterparty. Member connectivity, collateral and risk processes, and netting benefits make an active clearing rail costly to displace, although interoperability and competing CCPs keep the advantage contestable.
Clearing Settlement moat: definition, examples, and stocks
Erosion risks
- Competing CCP pricing and interoperability pressures
- Regulatory changes to clearing mandates or margin models
- Loss of venue flow reduces clearing scale and netting benefits
Leading indicators
- Trades cleared, net settlements, and net fee per settlement
- Clearing-member breadth and collateral efficiency
- Securities-financing transaction clearing adoption
Counterarguments
- Large incumbent CCPs can offer broader cross-product margin offsets
- Interoperability and regulation deliberately reduce venue-linked stickiness

Network
Two Sided Network
Strength
Durability
Confidence
Evidence
Cboe Europe's 24.4% share and €15.5bn Q2 average daily notional indicate a major liquidity pool. More orders can improve matching and execution, reinforcing broker routing, but share declined year over year and participants multi-home.
Two Sided Network moat: definition, examples, and stocks
Erosion risks
- Aggressive competitor pricing and incentives
- Routing changes by brokers due to best-execution and cost constraints
- The Australia disposal reduces the segment's geographic breadth
Leading indicators
- Market share and net capture (bps)
- Share in lit vs dark/auction venues
- European equities ADNV
Counterarguments
- Brokers can multi-home and shift routing rapidly based on economics
- Share fell from 25.1% to 24.4% year over year
Futures
Volatility and niche index futures (notably VIX futures) plus related market data/access
Q2 2026 net revenue was $30.6m of $731.6m. Segment operating income was $16.1m; operating_profit_share uses the $480.3m positive-segment denominator. Futures ADV fell to 222.7k from 239.2k year over year, while revenue rose 2% on higher market-data fees.
IP Choke Point
Legal
IP Choke Point
Strength
Durability
Confidence
Evidence
Ownership of proprietary indices and trademarks (e.g., VIX) supports exclusive branded volatility products and related licensing/market data monetization.
IP Choke Point moat: definition, examples, and stocks
Erosion risks
- Competing volatility benchmarks and products (e.g., alternative indices)
- Regulatory intervention affecting volatility derivatives market structure
- Sustained low-volatility regimes reducing demand and liquidity
Leading indicators
- VIX futures ADV and open interest
- Share of volume in VIX-related products vs alternatives
- Index licensing and data revenue tied to volatility products
Counterarguments
- Investors can trade substitutes (variance swaps, other volatility indices, options strategies)
- IP protects the VIX brand, but not the broader volatility-hedging need
De Facto Standard
Network
De Facto Standard
Strength
Durability
Confidence
Evidence
VIX functions as a widely referenced market volatility benchmark, supporting persistent demand for VIX-linked hedging and trading tools.
De Facto Standard moat: definition, examples, and stocks
Erosion risks
- Benchmark relevance declines if market participants shift to alternative measures
- Methodology changes or perception issues reduce trust
Leading indicators
- Media/market adoption metrics (VIX references, VIX-linked product launches)
- Stability and transparency of methodology governance
Counterarguments
- VIX is a benchmark, but liquidity and economics can still cycle strongly with volatility regimes
- Other volatility indicators (realized vol, other indices) can substitute in some workflows
Global FX
Institutional spot FX electronic trading platforms (ECN) and NDF execution (SEF)
Q2 2026 net revenue was $27.6m of $731.6m. Segment operating income was $15.5m; operating_profit_share uses the $480.3m positive-segment denominator. ADNV was $60.6bn and net capture was $2.96 per $1m traded.

Two Sided Network
Strength
Durability
Confidence
Evidence
Cboe FX has a modest liquidity network: maker participation can improve execution for takers and reinforce flow. Q2 ADNV of $60.6bn supports meaningful scale, but bank internalization, multi-homing, and intense venue competition prevent a stronger score.
Two Sided Network moat: definition, examples, and stocks
Erosion risks
- Multi-homing and ease of switching across FX venues
- Price competition compressing net capture
- Concentration of liquidity provision among a small set of banks/market makers
Leading indicators
- ADNV on Cboe FX platform
- Net capture rate per $1M traded
- Share of volume in core FX pairs vs competitors
Counterarguments
- FX is highly fragmented; liquidity can move quickly with pricing/incentives
- Large banks can internalize flow or route to preferred venues
Evidence
