Estate note. Heirs receive a stepped-up basis at death (§1014), eliminating built-in gain on inherited shares. Older holders who plan to bequeath rather than sell may rationally never de-concentrate.

The Chicago Mercantile Exchange traces to an 1898 butter and egg board, demutualized in 2000, listed in 2002, and then acquired the Chicago Board of Trade in 2007 and NYMEX in 2008. It operates the dominant markets in interest rate futures, equity index futures including the E-mini S&P 500, energy, agricultural, and metals contracts, plus the clearing house that stands between counterparties. Revenue rises with volatility and with hedging demand, making rate-cycle turning points unusually good for it. Headquarters are in Chicago.

Equity comp at CME Group

  • RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in CME, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with CME's option-implied volatility.

CME Group equity questions

How much CME stock is too much?
There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your CME position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
Does CME Group grant ISOs, NSOs, or RSUs?
Equity compensation at CME Group typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do CME Group RSUs use double-trigger vesting?
No. CME Group restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
