Three floor votes have not been enough to elect a new Speaker of the House. Jim Jordan has been losing ground with every vote, losing the first three votes with with 20, 22 and 25 Republicans voting against him:

So now we go to a fourth vote. How many Republicans will vote against Jim Jordan in the fourth round?

 - Jordan may or may not be the Republican nominee or he could pull out of the race before the third vote. Even if that happens, this market will still be live and will still resolve to the number of Republicans voting against him.
