The men's shot put at the 2018 IAAF World Indoor Championships took place on 3 March 2018.

Five throws into the competition, he threw 22.13 m (72 ft 7+1⁄4 in) to improve upon his own Oceanian record set while winning the previous championships.

Nobody would beat that mark in the competition, except Walsh himself, first equalling it in the third round then throwing 22.31 m (73 ft 2+1⁄4 in) as the final attempt of the day.

Indoor marks now being acceptable, that mark moved him to the number 15# performer in the shot put of all time, displacing Ryan Whiting who was in the competition.

In the final round, Romani couldn't get back on the podium with his 21.37m, a new South American indoor record, then Storl improved on his tie breaking position again.
