Oprah Makes $13.8 Million Tweeting About How Much She Loves Bread

We all love bread — but Oprah Winfrey is the only one who can make $13.8 million in a day talking about it.

On Tuesday, the new-ish Weight Watchers minority owner posted and pinned a tweet claiming that she’s lost 26 pounds on the popular program, despite eating bread every single day — a common no-no among the anti-carb movement.

Immediately after her Twitter post, WTW stock soared, settling up 19.51 percent for the day, or plus $2.17 per share.

Here comes the math lesson. Winfrey owns 10 percent of the company, or 15 percent when stock options are exercised. Weight Watchers has 63,621,022 shares outstanding, which would mean Winfrey owns 6,362,102.2 of those, without even exercising her option.

That means on Tuesday, Winfrey’s shares jumped in value a total of $13,805,761.80. Not bad for 31-seconds worth of work, and what sounds like a ton of ciabatta.

Here’s her tweet:

Eat bread. Lose weight. Whaaatttt? #ComeJoinMe https://t.co/jUgpk9ToXYhttps://t.co/xtnB53EwSf
