#1 United States Championship

The United States Championship is the most likely title to change hands before WrestleMania 34 for one simple reason: it currently has no holder.
Dolph Ziggler defeated Baron Corbin and Bobby Roode in a Triple Threat match at Clash of Champions to win the title for the second time in his career, seemingly ending speculation that his WWE career was almost over.

However, two nights later on SmackDown Live, Ziggler placed his new title in the middle of the ring, leaving fans with “something to remember him by”, and we haven’t seen him since.
A tournament to crown a new United States champion is currently taking place on SmackDown. Whether that leads to Ziggler's return or someone actually winning the title, we’ll have to wait and see. Whatever happens, a champion will surely be crowned before WrestleMania.
