A website published a national map that showcases the companies that raked in the most dollars in every state in 2015.

For example, in Oregon it was Nike, Costco in Washington, and Albertsons in Idaho.

There's also a few unrecognizable companies worth mentioning, like Poet in South Dakota, a company that specializes in Biofuel.  

When it comes to Montana? Stillwater Mining is the big winner out of Billings which made a little over $940 million dollars in 2015.
