Each year Bloomberg opens its doors to a host of stars for a day of money raising.

Musicians, sports stars, presenters, actors, actresses and models have all taken to the phones at Bloomberg Tradebook for their annual Charity Day.

These celebrities join Bloomberg employees in the office for a day of trading. All earnings from the day are then donated to charity causes.

Since the event started back in 2012, more than $4 million has been raised. 2016 generated $1m in donations alone.

Bloomberg Tradebook Charity Day isn’t your usual B-list event. The finance specialists have managed to attract some major names over the years.

Here’s a rundown of the biggest stars to have worked a shift during Bloomberg Tradebook Charity Day:

The first ever Bloomberg Tradebook Charity Day event, then known as Trick-or-Trade, was scheduled for Halloween. However, Hurricane Sandy pushed it back a week.
