Cboe adds daily Dow options

Cboe Global Markets began offering daily expirations for its Dow Jones Industrial Average index options on May 18, extending DJX contracts to Monday-through-Thursday maturities alongside existing Friday and monthly listings. The move gives DJX options contracts expiring every trading day, according to Cboe’s announcement and product pages. DJX options are exclusively listed on Cboe and are based on 1/100th of the Dow Jones Industrial Average, giving traders a smaller-sized contract tied to the 30-stock blue-chip index. (ir.cboe.com) The Chicago exchange operator tied the rollout to demand for shorter-dated index options. Cboe said zero-days-to-expiration, or 0DTE, index options accounted for a record 50.11% of its index options trading volume in the first quarter of 2026. (cboe.com) As of March 31, DJX open interest represented more than $472 million in notional value, according to the company’s release carried by third-party reports. ### How does the new DJX schedule work in practice? May 18 marked the start of Monday-through-Thursday DJX expirations, adding to the Friday and monthly contracts that were already available. Cboe’s contract specifications page says DJX options are cash-settled and European-style, and the product is listed on Cboe Options and Cboe C2 Options. (ir.cboe.com) The contract remains tied to 1/100th of the Dow Jones Industrial Average level. That sizing means a DJIA reading near 40,000 translates to a DJX level near 400, making the options smaller than contracts based on the full index value. ### Why did Cboe add more Dow expirations now? (ir.cboe.com) Cboe said the expansion reflects growing demand for short-dated index options trading strategies. Robert Ross, chief commercial officer at S&P Dow Jones Indices, said in the launch announcement that the companies were responding to investor demand for “more agile and transparent risk-management trading solutions.” January 8 is when Cboe filed a rule proposal to list P.M.-settled DJX options with daily, weekly, monthly and quarterly expirations, according to the exchange’s rule-filings page. (ir.cboe.com) That filing shows the daily-expiration launch followed an earlier regulatory step rather than a same-day product decision. (cboe.com) ### What does the 50.11% figure say about the market? The 50.11% figure means contracts expiring the same day made up just over half of Cboe’s index options volume in the first quarter. Cboe used that number to frame the DJX expansion as part of a broader increase in short-dated index trading activity. (ir.cboe.com) March 31 is the date Cboe cited for DJX open interest of more than $472 million in notional value. That figure gives a snapshot of the size of existing positions in the product as the exchange broadened the expiration calendar. ### Which market participants backed the launch? (cdn.cboe.com) Cboe said it had support from major U.S. and international retail brokers for the expanded DJX suite. The company’s announcement also named Wolverine Trading as one of the firms supporting the product rollout. S&P Dow Jones Indices was the named index partner in the launch. Ross said the additional expirations deepen that licensing collaboration around DJX options. (ir.cboe.com) ### Where can traders check the updated product details? Cboe’s DJX product page and contract specifications page now reflect the daily-expiration structure. (investing.com) The exchange’s 2026 options calendar and rule-filings page also provide the formal listing and scheduling details that brokers and traders use to track expirations.
