WWE Elimination Chamber: 5 little-known facts about the event 

#3. The United States Championship has never been defended in the Chamber

Ryback won the IC title in the Elimination Chamber back in 2015

Incredibly, after 16 years of The Elimination Chamber being seen as a match stipulation, the United States Championship has never been defended inside the steel structure.

The Tag Team Championships, WWE Championship, World Heavyweight Championship, Intercontinental Championship and this year The Raw Women's Championship have all been defended inside the Chamber.

It seems that a title as prestigious as the United States Championship will one day be defended inside the Chamber, but right now there is only the SmackDown Women's Championship, the Universal Championship and The United States Championship that are singles titles that haven't been defended inside the steel, but two of these Championships are less than two years old.
