A few thoughts. Ultimately, very hard to know how this will play out, but it is going to be fascinating.
Some of those "commercial" renters probably already have a lot of confirmed rentals in the next 11 months, and, since this change applies to bookings made after June 1st, they are probably very unlikely to sell any of those contracts until those pre-6/1/25 reservations are completed.
I imagine some of them are also waiting to see how this all plays out. Is this just some initial bluster by Disney and/or what is actual enforcement going to look like? If it looks more like bluster, they may keep going until they're told they have to stop or else. If Disney undertakes some actual, real enforcement, then they could start to conclude that the gig is up, and offload a lot of contracts.
Maybe we could see a slight uptick in resale contracts as people with extra points think, maybe I'd be better off unloading this contract before what might be an eventual dump of the commercial contracts in the next 6-12 months that could put downward pressure on resale prices. Maybe a few of the commercial contact holders have a few contracts they haven't rented out yet, and decide to offload those now as a hedge against potential action by Disney.
Just some thoughts. Personally, as someone who was doing some resale contract shopping last week, this seems like all the more reason to hold off for now and see how the dust settles.
