A while ago, @NoitUK, @Tetraspace, and I made markets for every constituency in the 2024 UK General Election. Over the past day or two, @AustinPlatt has written some code to extract the leaders in each constituency (and also a Monte Carlo simulation) to create a seat projection for the election based on the data from all of the 650 markets. This multi-market is for making predictions about how accurate that projection will be.
The projection can be found here: https://manifold-uk-election-2024.netlify.app/
But note that it updates regularly, so as the individual constituency markets are bet on, the overall projection will change. Therefore, this multi-market is based on the projection at the time of market creation, pasted below:

Please feel free to discuss the approach in the comments, and do add your own answers (I would make more to kick off, but it's so expensive these days...).
(I suppose if you believe the projection, you should buy the "X party will be within the 5-95 confidence interval" option to 90%. If you don't believe the projection, there must be some mana for you to make on the individual constituency markets...)
