The data broker industry reached $365 billion in revenue in 2025, trading detailed profiles on 4.6 billion individuals. Messaging metadata — who you contact, when, and how often — has become one of the most valuable data categories brokers buy and sell.
See why privacy-conscious users worldwide trust zero-knowledge messaging.
According to industry research, the global data broker industry generated $365 billion in revenue in 2025. Over 5,000 data broker companies operate worldwide, with the largest 50 controlling 78% of the market. The industry trades profiles on 4.6 billion individuals — more than half the world population. Average revenue per individual profile is $79 annually across all data categories.
Communication metadata is the fastest-growing data category for brokers, valued at $47 billion annually according to industry research. Messaging metadata reveals social graphs (who knows who), behavioral patterns (communication frequency), and inferred relationships (professional, personal, romantic). A complete messaging metadata profile sells for $0.50-$12.00 depending on the individual's value to advertisers.
According to industry research, messaging metadata enters the broker ecosystem through three primary channels: direct platform data sharing (42%), app SDK data collection (31%), and carrier metadata sales (27%). Platforms that share data with parent companies or advertising partners provide the largest volume. WhatsApp's metadata sharing with Meta alone affects 2.4 billion user profiles in broker databases.
According to industry research, 14 countries enacted data broker registration requirements in 2025. The FTC took action against 12 data brokers for illegal messaging data collection. California's data broker registry now lists 489 registered companies. Vermont's broker law resulted in $23 million in fines. The era of unregulated data brokerage is ending, but the industry adapts faster than regulation.
