This resolves YES if there is any 538-branded election model for the 2028 election.

It could also be a model under another name as long as it's clear that it's a successor model based on the 538 IP. For example, if the LA Times acquire 538 from ABC/Disney and then rebrand it as FiveThirtyLA, or the California Election Model (and then in fine print at the bottom of the website it says it's based on the 538 election model) or something like this, that would be adequate too.

Since there is some degree of subjectivity, I will not bet in this market.
