The Chicago Board Options Exchange (CBOE) and S&P Dow Jones Indices (S&P DJI) have extended their exclusive licensing agreement by 25 years through 2051. This renewal continues a partnership spanning more than four decades since the launch of S&P 500 Index options in 1983. Under the extended terms, CBOE retains exclusive listing and trading rights for S&P 500 Index options. The parties also plan to explore innovative product development, including tokenized options contracts, as part of the long-term agreement.
