September 2026 futures roll date and expiration for ES, NQ, RTY and YM
September 2026 equity index futures roll on September 14, 2026 and expire on September 18, 2026. Traders watch this cycle because ES, NQ, RTY and YM liquidity typically migrates into the next lead month around the Monday roll date.
dates for this quarterly cycle
Roll date: September 14, 2026
Expiration date: September 18, 2026.
CME lists Monday September 14, 2026 as the customary roll date and Friday September 18, 2026 as expiration for U.S. equity index futures. After the roll date, the December contract becomes the customary lead month.
Why this roll matters
September 2026 is a standard quarterly equity-index roll month, which means liquidity, open interest and execution quality typically migrate from the expiring contract into the next quarter around CME's customary roll date.
For ES, NQ, RTY and YM traders, the practical issue is not just the calendar. It is knowing when the contract you are watching stops being the cleanest place for price discovery and when the next lead month starts carrying the real volume.
What changes after the roll date
CME states that the customary roll date for U.S. equity index quarterly futures is the Monday prior to the expiration week settlement date, and after that roll date the second-nearest expiration month is typically treated as the lead month. In this cycle, that means December 2026 becomes the contract month traders usually watch most closely after September 14, 2026.
That lead-month switch matters because charts, VWAP levels, DOM depth and apparent intraday range can all look different once liquidity fragments between two contracts instead of sitting cleanly in one front month.
