You’ll Never Guess How Much Money It Costs to Host the Summer Olympics

But new research from credit-score company WalletHub uncovered some lesser-known facts about the Rio Games. Whip out one of these whoa-inducing nuggets whenever there’s a conversation lull at your Olympics viewing party:

1. The estimated cost of hosting the 2016 Rio Olympics is a whopping $11.5 billion. Yowza. 

2. Safety is the name of the game. There will be 85,000 security personnel working at the Rio Games (more than twice as many as the 2012 London Olympics).

3. There were 26,000 cases of Zika virus reported in Rio during the first three months of 2016. (But—phew!—there’s been a 90 percent decrease in Brazilian cases between the third week in February and the first week in May.)

4. Over the years, Team USA has won 2,406 Summer Olympic medals (the most of any country). Here’s hoping we rack up a few more!
