Walmart in early talks to buy Humana

The Wall Street Journal reports that Walmart Inc. could potentially be buying Humana Inc., though nothing is finalized and it isn't clear what terms they're discussing.

Why it matters: Per the Journal, if the deal went through it could "transform Walmart overnight into one of the nation's largest health insurers." Humana is valued at $37 billion currently, while Walmart sits at $260 billion.
