Cents of profit per dollar of sales
After paying all the costs of running the apps, the cents of operating profit left from each dollar. A 48% margin means nearly half of every dollar drops through — the sign of a business with no real substitute.

Operating margin
You only earn *48¢* on the dollar when customers have nowhere else to go. That's the network effect, measured.

A 48% margin on a free product is the payoff from owning the places people connect. Meta didn't build just one of them — it bought or built the biggest ones, so leaving any single app still leaves you inside Meta's world. Here's how that position came together.
How the network was built
2004
Facebook launches; your real-world friends move online together.
2012
Buys Instagram for $1B — locking up the next generation.
2014
Buys WhatsApp — the messaging layer for much of the world.
Now
3.56B daily users; AI targeting makes each one more valuable to advertisers.
Pricing power, in the numbers
Ad impressions delivered across our Family of Apps increased by 19% year-over-year. Average price per ad increased by 12% year-over-year.
↳ Showing more ads and charging more for each is the textbook signature of pricing power — advertisers keep paying up because nowhere else reaches this many people this precisely.
