Cboe Global Markets just re-upped its most lucrative marriage on Wall Street — and locked in the terms for a quarter-century. The Chicago exchange operator and S&P Dow Jones Indices announced Tuesday that they have signed a 25-year extension of their exclusive licensing agreement, keeping Cboe as the sole venue for trading options on the S&P 500 Index through 2051.

The pact, disclosed in an 8-K filing with the Securities and Exchange Commission dated September 28, hands Cboe continued exclusive rights to create, list, trade, clear and settle standardized SPX options contracts in the United States, plus cross-licenses tied to the Cboe Volatility Index (VIX) and related benchmarks. It stretches a partnership that, per the companies, dates back more than 40 years to the 1983 launch of SPX options — the product that turned Cboe into the epicenter of index-derivatives trading.

"Cboe brings deep expertise in developing, listing, and operating liquid derivatives markets that complements our index expertise," S&P DJI chief executive Catherine Clay said in the joint announcement.

"THIS EXTENSION ALLOWS US TO FURTHER GROW OUR SPX AND VIX FRANCHISES, WHILE PROVIDING THE CERTAINTY AND CONTINUITY THAT OUR CUSTOMERS HAVE COME TO EXPECT IN THESE PRODUCTS." — Craig Donohue, CEO of Cboe Global Markets

The numbers explain why both sides wanted certainty. SPX options notched a record 970.6 million contracts traded in 2025, with average daily volume of 3.9 million contracts — up 25% year-over-year and the fourth straight year of record activity, according to the companies' release. That volume is the engine behind a large share of Cboe's transaction revenue, so a lapse or a rival bid for the license would have been an existential risk to the franchise.

Investors treated the news as a green light: Cboe shares jumped as much as 5.83% to $268.01 on Tuesday, Yahoo Finance reported, among the day's biggest gainers on the exchange-operator side of the market.

The fine print — and the crypto angle

Cboe's own follow-up filing was careful to manage expectations on money. The company said the current 2026 royalty terms are untouched, with updated per-contract license fees kicking in January 1, 2027. Cboe estimates that reset will have a "de minimis impact" on its 2027 net revenue growth and expects subsequent adjustments to be smaller still, with full 2027 guidance due alongside fourth-quarter earnings in February.

The more forward-looking wrinkle: the two companies said they may also explore products beyond traditional listed derivatives, including tokenized versions of S&P 500 options, though neither firm committed to a specific product or launch date. It's a nod to how quickly traditional exchanges are being pushed to at least study blockchain-based market structure, even for their crown-jewel products.

For now, the deal mostly buys both companies what they wanted most: no drama. Cboe's SPX and VIX complex — the products that make its options business the envy of rival exchanges — stays locked in through 2051, and S&P DJI keeps its most important derivatives partner under exclusive contract for another generation. Wall Street will get its next real data point on the arrangement's economics in February, when Cboe details exactly what the 2027 fee reset means for its bottom line.
