Amazon’s entry into the health care industry, by the numbers

Amazon is no stranger to disrupting industries. But with its tentative entrance into health care, along with Berkshire Hathaway and JPMorgan Chase, it might have challenged its biggest industry yet.

When Amazon announced today that it might be starting its own health care company, health care stocks, predictably, fell. Health services and health technology sectors declined more than any others in the Dow Jones Industrial Average today.

Health insurance companies like UnitedHealth suffered the worst, followed by pharmaceutical companies like Pfizer.

These declines aren’t disastrous by any means. The thing is, the health care industry is huge and any disruption in the industry could have far-reaching effects on Americans. Spending on health care accounts for nearly 20 percent of the U.S. GDP. Health care is also now the biggest employer in the U.S.

Health care companies — especially pharmaceutical and biotech companies — have huge profit margins, especially compared to Amazon. The Amazon, Berkshire Hathaway and JPMorgan Chase consortium could make a dent in those as it tries to reduce costs “through an independent company that is free from profit-making incentives and constraints.”

And Amazon, Berkshire and JPMorgan are huge and have plenty of technology know-how they could bring to bear on the health care industry. Check out their market cap compared to the biggest U.S. health care companies.

For now, Amazon et al. are only hoping to roll out this health care company to their employees. The real threat to other health care companies would be if Amazon decided to eventually roll out this program more broadly.

As Barclay’s analysts noted today, “we are never dismissive of anything disruptive that Amazon is involved in.”

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
