Chainalysis' latest Crypto Crime Report reveals that illicit digital asset activity surged to an estimated $154 billion to $158 billion in 2025, a record high. Stablecoins accounted for the majority of these transactions, reflecting their dominance as the go-to medium for all on-chain activity — legitimate or not. The report highlights that Chinese-language money-laundering networks processed $16.1 billion in illicit crypto last year, roughly 20% of known global laundering volume.
Why Stablecoins Lead Illicit Flows
When asked why stablecoins are the preferred instrument for criminals, Chainalysis co-founder said it's expected: stablecoins are the most used medium for on-chain transactions overall — fast, stable price, efficient cross-border movement. Illicit actors use whatever the market uses. The upside: every stablecoin transaction is recorded on a public ledger, issuers can freeze assets, and the data trail is rich — if investigators have the right intelligence tools.
Chinese-Language Networks: $44M a Day, Global Reach
These networks operate via forums, Telegram channels, and escrow marketplaces, moving roughly $44 million per day across nearly 1,800 wallets. They've become the connective tissue linking disparate cybercrime globally — a global infrastructure problem, not a regional one.
State Actors and Industrialized Crime
Chainalysis notes a fundamental shift in 2025: nation-states — sophisticated, well-resourced governments — systematically leveraging blockchain to evade sanctions and move funds at scale. This threat is qualitatively different from ransomware gangs. Meanwhile, crypto crime has industrialized: laundering-as-a-service, infrastructure providers, and brokers now function like the back office of a criminal enterprise, compressing decades of traditional financial crime evolution into a few years.
AI Countermeasures: From Manual Tracers to Intelligent Agents
To keep pace with AI-powered crime, Chainalysis launched its first blockchain intelligence agents — AI capabilities built on top of its proprietary data platform. These agents analyze complex transaction flows, enrich alerts, and generate investigative leads in minutes instead of hours. Over the past decade, Chainalysis tools have helped freeze or recover over $34 billion in illicit funds. The firm stresses that defenders must scale intelligence capabilities faster than criminals, as AI lowers entry barriers and accelerates attack sophistication. The race to build trust infrastructure for the on-chain economy is on.
