UnitedHealth Group, with its fourth-quarter results announcement Tuesday, revealed that it passed $200 billion in full-year revenue for the first time in 2017.

The Minnetonka-based company, which is the nation's largest provider of health insurance and the leader in health data services, has been one of the fastest-growing in country this decade. It doubled in size from $100 billion in just six years, a pace that only Walmart has matched and only Apple has beaten.

Amazon is on track to make that doubling in just three years, beating them all at speedy growth.

McKesson Corp., the U.S. distributor of health products and pharmaceuticals, had $198 billion in fiscal 2017 revenue and may surpass UnitedHealth when it reports the figures for its 2018 fiscal year, which ends March 31.

Only a handful of state-run companies, such the world's largest oil company Saudi Aramco at $311 billion, surpass $200 billion in annual revenue.

The world's largest privately-held company, Cargill Inc., is based in Wayzata. Its revenue will come in around $120 billion this year.
