1. United States of America
Production of helium in 2018 (in million cubic meters): 90
Production of helium in 2019 (in million cubic meters): 89
Easily topping the list of 7 largest helium producing countries in the world is the United States, whose helium production is greater than the other 6 combined. It would be safe to say the US has a global monopoly on production and by proxy, supply of helium, due to its vast reserves, dwarfing the reserves of other countries.
