Instagram Passes 50 Million Users, Adds 5 Million a Week
So maybe that $1 billion it cost Facebook to buy Instagram was a bargain after all. — The photo-sharing app is on fire. It now has more than 50 million users — and is adding new ones at the rate of roughly 5 million per week, according to its API.
Context & Ripple Effects
Instagram's growth curve has been steepening all spring: it reported 27 million registered users on March 11 while teasing its first Android build, and by early May it counts more than 50 million users, adding roughly 5 million a week according to its own API — growth that arrives weeks after Facebook agreed to pay $1 billion for the two-year-old company.
The timing sharpens the debate around that price tag: Mashable's framing of the deal as 'a bargain' echoes across eight outlets picking up the story, and it lands just as Facebook heads into a rumored IPO roadshow where its almost entirely advertising-driven, $1-billion-a-quarter revenue model is the thing investors will scrutinize.
First-order effects
- Facebook's $1 billion outlay for Instagram now prices at roughly $20 per user and falling fast, giving the acquirer an unusually strong talking point heading into its IPO pitch to investors.
- The Android launch that was teased in March appears to be doing its job — the weekly intake of about 5 million new users implies most of the recent surge is coming from beyond the iPhone base Instagram was built on.
Second-order effects
- Facebook already faces confirmed advertiser frustration with its ad products despite reach approaching 15 percent of the world's population; a fast-growing, engagement-heavy mobile property gives it a second surface to prove mobile advertising can work before the offering.
- Rival platforms competing for mobile attention and for advertiser budgets now face a photo-sharing incumbent that is compounding at millions of users a week rather than a niche iOS app they could ignore.
Third-order effects
- If a revenue-free photo app can command a ten-figure acquisition price on user momentum alone, mobile-first audiences are being valued ahead of monetization — a template other founders and buyers will follow, and one regulators and investors will have to judge differently from web-era deals.
- The deal signals consolidation of mobile social around a small set of gatekeeping platforms: standalone apps either scale fast enough to be bought or get squeezed between the few companies large enough to fund distribution.
The trend: Mobile-native social apps are being acquired and valued on audience velocity rather than current revenue, with Facebook's Instagram purchase the clearest early data point in that shift.
