After Kylie Jenner Tweeted The New Snapchat Format Was Sad Their Stock Plummeted (Photos)

You might not like the Kardashian-Jenner Clan, but they have some power.

Case in point.

Kylie Jenner just used Twitter (TWTR) to wipe $1.3 billion off the market value of Snapchat-parent Snap (SNAP).

The social media company’s shares fell as much as 7.2 percent Thursday after the reality TV star posted a tweet to her 24.5 million followers effectively declaring Snapchat over. “[S]ooo does anyone else not open Snapchat anymore? Or is it just me… ugh this is so sad,” she wrote.

The CEO still getting paid, but still that is a lot of market value to lose over a twitter.
