Cboe’s 25-Year S&P 500 Deal Puts Tokenized Options on the Table

Cboe Keeps SPX Rights Through 2051

Cboe and S&P Dow Jones Indices have extended a relationship dating back to 1983 for another 25 years, giving Cboe exclusive rights to offer its flagship S&P 500 Index options, or SPX, through 2051. Buried in the otherwise conventional licensing announcement, however, was a reference to something considerably newer.

The companies said they may collaborate on products beyond traditional index derivatives, specifically naming tokenized options contracts. There’s no product yet, and the announcement offered no blockchain, launch date, settlement structure, or regulatory details. For now, it amounts to an option to explore the idea rather than a commitment to build it.

SPX Trading Hit a Record in 2025

The reference is notable because of the size of the existing SPX market. Cboe said 970.6 million SPX options contracts traded in 2025, a record, while average daily volume reached 3.9 million contracts. Annual volume increased 25% and marked a fourth consecutive yearly record.

SPX options have been around since 1983 and provide cash-settled exposure to movements in the S&P 500. The new agreement effectively preserves the existing arrangement for another generation while allowing Cboe and S&P DJI to consider how the franchise could change as financial markets experiment with tokenized assets.

S&P DJI CEO Catherine Clay described that broader objective in terms of giving investors different ways to access the benchmark, stating:

“The S&P 500 is the definitive barometer of U.S. equity market performance and the most widely tracked index in the world. Investor demand for exposure to U.S. equities continues to accelerate, and we see a future where every investor, everywhere, can access this benchmark in the format that best suits their needs. Cboe brings deep expertise in developing, listing, and operating liquid derivatives markets that complements our index expertise, and this agreement allows us to keep innovating for the next generation of investors.”

The reference to different formats doesn’t necessarily mean blockchain. In this agreement, however, tokenized options are specifically listed as one area the companies may explore.

S&P Has Already Licensed Onchain Products

That possibility also has some precedent. S&P DJI has already licensed the S&P 500 for blockchain-based products, although none are equivalent to an SPX option. S&P licensed the benchmark to Centrifuge for SPXA, a tokenized S&P 500 index fund, and in March 2026 licensed it to TradeXYZ for an S&P 500 perpetual contract on the perps DEX Hyperliquid for eligible non-U.S. traders. The index provider has also worked on bringing licensed index data into blockchain systems.

Cboe has separately expanded its crypto derivatives business. Its existing products include cash-settled bitcoin and ether futures, bitcoin exchange-traded fund (ETF) index options and other crypto-linked derivatives. Those efforts remain distinct from the SPX business covered by the new licensing agreement. The Sept. 29 announcement is where those two areas overlap, at least on paper.

A Tokenized Option Would Bring More Moving Parts

A tokenized SPX-style option would also be more complicated than simply putting an index price onchain. Options require strike prices, expiration terms, collateral arrangements, pricing data, and settlement rules as well. Any U.S. product would also have to fit within the applicable regulatory and clearing framework.

None of those details were disclosed because Cboe and S&P DJI haven’t actually announced a tokenized SPX product. The companies said only that their extended agreement allows them to collaborate on such products in the future.

For the moment, the concrete part of the announcement is much simpler. Cboe, originally the Chicago Board Options Exchange, has secured exclusive SPX options rights through 2051 after the franchise handled nearly 1 billion contracts last year. Tokenized options are now contemplated by the agreement, but they remain an idea rather than a market.
