These companies collectively have hundreds of thousands of employees that cost many billions each year to insure. Large U.S. employers are what you call in the industry "self funded", meaning they collect premiums from their own funds + employee contributions into a big pool and pay out claims from this pool (i.e. they take on all the insurance risk). Any optimizations they can make to plan administration, healthcare utilization (i.e. incentivizing employees to choose less expensive forms of healthcare or get healthier), lower drug costs, lower administrative cost, etc. will save them many billions of dollars annually. Saying this new venture is going to be free of profit-making is a bit like saying water is "sugar free." This is all about lowering their own cost of employing a massive workforce.
