Three of the wealthiest and most powerful companies in the U.S. — Amazon, Berkshire Hathaway and JPMorgan Chase — are starting a new health care company. Details are thin, but the new entity will be “free from profit-making incentives” and focus on employer-based health benefits, the companies said in a statement.

Why it matters: The health care industry was already beside itself over the prospect that Amazon, on its own, might enter the pharmacy business. Amazon along with Berkshire Hathaway and JPMorgan can bring to bear resources that few existing companies have the power to match.
