Chainalysis

$2.7 billion in crypto was stolen in 2025, keeping Chainalysis central to coverage of illicit finance, DeFi security and market surveillance.

Who they are

Chainalysis appears in coverage as a blockchain-analytics company whose research quantifies cryptocurrency adoption, illicit flows, sanctions exposure and fraud, while its tools are used in security and compliance settings. The reporting also tracks it as an operating company, including co-founder Jonathan Levin’s elevation to CEO after Michael Gronager’s departure and its purchase of AI-agent security startup Alterya.

The recent arc

Coverage reached a recent high in 2023Q4, when Chainalysis publicly challenged reports that crypto use by terrorist organizations had been measured with “flawed analyses.” That episode underscored a recurring role in the news: not merely supplying crypto-crime figures, but contesting how those figures are interpreted in politically charged contexts.

The story then shifted toward an expanded security-and-surveillance remit. In 2025, reports used Chainalysis data to describe stablecoins displacing bitcoin in illicit transactions, concentrated gains and widespread losses in the $TRUMP memecoin, and rising DeFi attack risk; the company also bought Alterya and named Levin CEO. The most recent headline moves into prediction markets, with Polymarket deploying Chainalysis detection tools to surface patterns consistent with insider knowledge.

The tension

The central tension is between crypto’s expanding financial use and the ability to identify harmful or unlawful activity without overstating it. Chainalysis and rival TRM Labs have both put the 2025 theft total at $2.7 billion, while Chainalysis has highlighted illicit balances, sanctions-linked addresses and DeFi vulnerabilities; yet its 2023 response to terrorism-financing coverage shows that attribution and measurement remain contested. Its partnership with Polymarket extends that same monitoring logic from theft and sanctions into market-integrity questions.

Why it matters

If this trajectory holds, Chainalysis’s relevance could increasingly depend on whether blockchain intelligence becomes embedded across more financial venues, from DeFi protocols to prediction markets, rather than remaining primarily a post-incident forensic tool. The reported migration of illicit activity toward stablecoins, growing DeFi exposure and continued major hacks make demand for monitoring plausible, but the company’s influence will also hinge on the credibility and interpretation of the data it supplies amid competition from firms such as TRM Labs.
