Previously, and since 2020, the MLS Clear Cooperation Policy had required brokers to submit listings to MLS, within one (1) business day of publicly marketing the listing, and all listings were immediately available on the IDX. This policy is no more.
Now, and at least as of September 30, 2025, NAR has established the Delayed Marketing Exempt Listings Rule where all listings will be required to be available through the MLS to all participants and subscribers, but not by IDX if the seller signs a disclosure agreement (also, the seller disclosure prevents brokers from engaging in syndication).
This IDX / MLS dichotomy results in giving the MLS (and its participants and subscribers) a clear advantage over other online platforms (and non-NAR / MLS real estate licensees) where the result likely will steer consumers towards working with real estate licensees affiliated with NAR, to the detriment of non-NAR / MLS real estate licensees, because that is who will have the most up-to-date information.
It is acknowledged that MLS does also permit consumers to elect to have an Office Exclusive Exempt Listing, which permits a seller to have their property only marketed with their brokerage for a set period of time. However, unlike the Delayed Exempt Listings Rules, any act of public marketing on the Office Exclusive Exempt Listing, such as putting up a sale sign on the property, ends the Office Exclusive Exempt Listing resulting in immediate sharing throughout the MLS with participants and subscribers, but not necessarily on the IDX.
Is it time for Sitzer 2.0?
