How to estimate it

Fermi’s official “Napkin math”

The easiest place to start is Netflix's roughly 300 million memberships worldwide. Accounts get shared, so call it 600 million people who actually use it. How many are watching this exact second? Not many, maybe 1 in 30.

Netflix memberships worldwide
≈ 300,000,000
Viewers per membership (shared accounts)
× 2
Watching at this exact moment
÷ 30
300M × 2 ÷ 30
≈ 20 million

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference
Netflix hours watched, full year 2025 (Netflix's own "What We Watched" reports)
≈ 191 billion
Hours in a year
÷ 8,760
191B ÷ 8,760
≈ 21.8 million
