One-third of the country may not have any competition on Obamacare’s exchanges in 2017, leaving consumers with fewer choices for coverage, a new analysis has found.

The analysis, from research firm Avalere Health, concluded nearly 36 percent of Obamacare exchange regions might have only one insurer offering 2017 plans. The prediction comes as major insurers have announced plans to flee some Obamacare exchanges next year due to mounting financial losses.
