How to estimate it
Fermi’s official “Napkin math”
Instagram has about 2 billion users. How many of them tapped like on Messi holding the World Cup? Soccer is the world's biggest sport, so maybe 1 in 25.
- Instagram users
- 2,000,000,000
- Liked Messi's photo
- ≈ 1 in 25
- 2B ÷ 25
- ≈ 80,000,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
