NYSE is publically available information from the exchange directly. Listing services lock listings behind portals only accessible to agents that are members of NAR, the general public has no access to those listings or that data. There is still much information asymmetry in NA real estate as many metropolitan regions may feature 2, 3, or more MLSs. The state of Georgia has 25 MLSs in total, of which few, if any, share their listings with each other. So an agent in Atlanta who is a member of FMLS, has to pay $300 or more (plus a broker paying $800+) to become a member of the Golden Isles MLS if they have a client that wants to sell in Savannah, or even if they themselves want to buy in that area. Zillow is what helps reduce this information asymmetry on a national scale, but they have to pay licensing fees to these individual MLSs/NAR to access that information. As NAR requires agents to list properties on their local MLS (and advocates against posting on other sites separately), NAR creates a market where Zillow is reliant on them, and NAR becomes the arbiter of who has access to what information. Information that, for no reason, should really be remaining available to the general public.
