If anyone using these platforms, nothing changes today. You are not at risk of an insider trading charge for having an opinion.
What changes over a longer horizon is the regulatory character of the venue. These cases establish that market abuse law reaches event contracts. That invites the apparatus that comes with financial markets - surveillance obligations, reporting, position monitoring, potentially registration thresholds for large participants.
That apparatus lands on the platforms first. It tends not to stay there. The endpoint of "this is a financial market" is that participants in it get treated as market participants, with the documentation that implies.
Not this year. Probably not next. But that's where the argument runs once you've won it.
