Bloomberg reported that the timing of the tweet may have caused a drop in stock for Snap Inc., the company that owns Snapchat.
"Shares sank as much as 7.2 percent Thursday, wiping out $1.3 billion in market value, on the heels of a tweet from Kylie Jenner," the publication said.
According to a Wednesday tweet from Reuters, the drop in Snap's stock adds up to about $1.5 billion lost in market value.

Ten minutes after the first tweet, Jenner said she still has love for the app.
“Still love you tho snap,” she tweeted. “My first love.”
Jenner, who welcomed her first child, daughter Stormi Webster, Feb. 1, may have not opened the app because she's busy with her little one and boyfriend Travis Scott.
