Vulnerability Economics

What is a bug worth?

A multi-edition exploration of how the market for software vulnerabilities actually clears — what counts as a bug, who buys it, and how its price is set. The 2026 model is stress-tested against a corpus of ~150 confirmed historical exploit and surveillance-product transactions drawn from court records, leaked invoices, government disclosures, and journalism.
