An Industry You Have Never Heard Of
There is an entire industry built around collecting, packaging, and selling your personal information. Most people have never heard of it. The companies that do this are called data brokers, and they work almost entirely behind the scenes.
A data broker collects personal information from dozens of sources, organizes it into a detailed profile about you, and then sells that profile to anyone willing to pay. Marketers, insurance companies, employers, political campaigns, law enforcement, and even other data brokers. You never signed up for their service. You never agreed to their terms. They just collect information about you and sell it.
The numbers are staggering: There are over 5,000 data brokers worldwide. The global data broker industry is valued at nearly $434 billion. A unified database project identified over 750 registered brokers across just five U.S. state registries. The world generates over 402 million terabytes of data every single day. About 70% of all that data is generated by regular people like you, just going about their lives.
Where They Get Your Information
Public Records
When you register to vote, buy a house, get married or divorced, register a car, or appear in court records, all of that becomes public. Data brokers systematically harvest these government databases.
Your Online Activity
Every website you visit, every search you run, every product you look at generates data. Tracking tools embedded in websites and apps quietly send your browsing behavior, purchase history, and location data to data aggregation companies. Most of the time, you have no idea it is happening.
Loyalty Programs
That loyalty card at the grocery store, the points program at your coffee shop, the rewards card at the gas station—all of these are data collection tools. Every purchase gets tracked, recorded, and often sold to brokers who use it to build profiles about your spending habits, dietary preferences, and lifestyle.
Your Phone
Many apps on your phone contain hidden third-party code that collects your location, device information, and usage patterns. That data gets transmitted back to data aggregation companies, which then sell it. A single piece of third-party code can be embedded in hundreds of different apps, meaning one company can collect data from millions of people at the same time through apps those people use every day for completely unrelated purposes.
Social Media
Anything you post publicly, and often things you think are private, becomes fodder for data brokers. Your interests, connections, photos, check-ins, and comments all contribute to the profile being built about you.
How Much Is Your Data Actually Worth?
Here is where it gets real. Your personal information is not just being collected for fun. It is generating massive revenue.
- The global data broker industry is valued at nearly $434 billion as of 2025 and growing every year.
- Research has estimated that companies like Meta generate hundreds of dollars per year from a single American user's personal data through targeted advertising alone.
- Smart TV manufacturer Vizio publicly admitted in 2021 that selling viewer data generated more profit than selling the televisions themselves. Think about that: the product you paid money for is also the tool they use to make even more money off your behavior.
- The big data analytics market overall has surpassed $348 billion and is projected to reach over $924 billion by 2032.
- The world generates over 402 million terabytes of data every single day, and roughly 221 zettabytes are expected to be generated in 2026 alone. To put that in perspective, one zettabyte is a trillion gigabytes.
What They Know About You
The profiles that data brokers build are far more detailed than most people imagine. A typical profile might include your full name, current and past addresses, phone numbers, email addresses, age, birthday, marital status, your family members' names, income level, education, employment history, credit score range, political affiliation, health conditions, purchase history, car make and model, websites you visit, and your precise GPS location history.
They also sort people into categories and sell access to those groups. Categories include things like "young mothers," "single fathers," "fitness enthusiasts," "recently divorced," "chronic pain sufferers," and "financially distressed." These labels are applied to you by algorithms, and they follow you across every company that buys your profile.
The Real Dangers
Identity Theft and Scams
Criminals buy data from brokers to make scams more believable. Instead of generic phishing emails, scammers now purchase detailed profiles to craft personalized scams that reference your name, your bank, your recent purchases, and your family members. AI-powered scams in 2026 increasingly rely on this purchased data to impersonate people and companies you actually deal with.
Stalking and Harassment
People-search websites, a type of data broker, make your personal information accessible to anyone with an internet connection. Your current address, phone number, workplace, and family members' names can be purchased for just a few dollars. This has been used by stalkers, abusive ex-partners, and hate groups to locate and target people.
Government Surveillance Without Warrants
In 2018, the Supreme Court ruled that law enforcement needs a warrant to get cell phone location data. But nothing stops government agencies from simply buying that same data from brokers. Multiple investigations have confirmed that U.S. military, intelligence agencies, and local police have purchased location data and personal information from data brokers, bypassing the warrant requirement entirely.
How To Fight Back
California's DROP System
In January 2026, California launched the Delete Request and Opt-Out Platform (DROP). If you are a California resident, this free system lets you submit one deletion request that reaches every registered data broker in the state. Brokers must process these requests by August 2026 and continue deleting every 45 days.
Manual Removal
If you are not in California, you can still request deletion from individual brokers. Find their privacy policies or consumer request forms and submit requests. Under most state privacy laws, they have 45 days to respond.
Data Removal Services
Several services automate the removal process on your behalf. They monitor broker sites for your information and submit removal requests when your data reappears. These services charge a subscription, but they save a lot of time.
Ongoing Habits That Help
Removing your data once is not enough because brokers continuously re-collect. Use email aliases when signing up for new services so you can track who sells your information. Give minimal personal information on forms. Opt out of marketing and data sharing wherever you see the option. The goal is not invisibility—it is making your profile harder to build and resell.
The mindset shift: Total digital invisibility is not realistic. But you do not need to be invisible. The goal is friction. When you make it harder for brokers to collect, link, and resell your data, you dramatically reduce your exposure.
