Answer & explanation
Official answer
13,969,000,000
cans
How to estimate it
Fermi’s official “Napkin math”
The easiest place to start is the world population, about 8 billion. How many Red Bulls does the average person drink in a year? Most people never touch the stuff, but the ones who do drink a lot, so call it 1.5 cans per person on average, which works out to around 12 billion cans.
- World population, roughly
- 8,000,000,000
- Average cans per person per year
- × 1.5
- ≈ result
- 12,000,000,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Cans sold worldwide, 2025 (Red Bull GmbH reported)
- 13.969 billion
- Growth vs. 2024
- +10.2%
- ≈ result
- 13,969,000,000
