From strictly a matter of measuring stockpiles of weapons and their relative sophistication, I think the USA is still arguably a hyper-power.
From wikipedia. Hyperpower
A hyperpower is a state that dominates all other states in every sphere of activity (i.e. military, culture, economy) and is considered to be a step higher than a superpower. The term often refers to the United States of America due to its status as the world's only current superpower; however, its possible status above that remains a topic of dispute.
USA clearly not "dominates all other states in every sphere of activity". Take the Syrian war or Crimea as example: USA were infuriated by what rival powers has done, but were unable to stop them.
USA will become true hyperpower only when they subjugate both Russia and China and there will be no any other strong and independent competitors. I think this is highly unlikely and becoming less and less likely with time.
