Cash settlement is what makes a futures contract on a privately held company viable. Without it, expiration would require delivery of the underlying security, and when no publicly tradable share exists, that obligation cannot be met. CME Group's Monday launch of cash-settled single-stock futures on 55 U.S. equities, including SpaceX and Micron, sits squarely on that design choice.
Where this sits in the product stack
CME Group introduced the contracts on 55 U.S. names. Alongside the standard-size series, the exchange launched micro-sized contracts on 22 of those same names. The micro format reduces the notional exposure per contract, which changes minimum capital requirements and affects how precisely a participant can size a position. Both series became available Monday.
Trading runs 23 hours a day. Futures markets can operate extended sessions under their regulatory framework in ways that equity markets cannot, and CME Group is using that capacity here. The longer window gives participants time to react to company-specific news arriving outside conventional equity trading hours.
The SpaceX question in futures form
SpaceX does not have publicly traded shares. That status creates a settlement problem for any exchange-listed product referencing its price, and cash settlement is how CME Group resolves it. Positions close against a defined reference price rather than through delivery of stock.
A futures settlement price is a market-generated number, produced by the interaction of buyers and sellers in that contract. It is not a certified appraisal of company value. For Micron, which does trade publicly, the cash-settled structure is a design choice. For SpaceX, it is the only structure that makes the product possible.
CME Group's contract specifications govern the reference price calculation for each name. For a publicly traded stock, that reference can be anchored to observable prices in the underlying. For SpaceX, the methodology necessarily relies on something else, and participants planning to use the futures price as a valuation signal should read those terms before trading.
The micro contract and position sizing
The 22-name micro series addresses one specific constraint: the minimum capital required per position. Micro contracts carry a smaller notional size, letting participants express directional views at lower dollar exposure than the standard contract allows. CME Group launched both the standard and micro series simultaneously on Monday.
