Many critics continue to view Bitcoin as a payment rail built primarily for criminals. The Chainalysis Crypto Crime Report 2026 paints a different picture. Illicit cryptocurrency transaction volume did reach a record high in 2025 at USD 154 billion, yet it accounted for less than 1% of total on-chain volume.

The myth of the criminal currency traces back to the darknet marketplace Silk Road, whose early years ran from 2011 to 2013. Even though analytics firms produce differing figures, that early image still shapes public debate today. Independent researcher TRM Labs puts illicit volume for 2025 at USD 158 billion, or 1.2% of total volume, marking the same order of magnitude as Chainalysis. Both firms also revise prior-year figures upward over time; Chainalysis lifted its 2024 estimate from USD 40.9 billion to USD 57.2 billion.

Record USD 154 Billion Remains a Fringe Phenomenon

The record absolute sum and the sub-1% share do not contradict each other. Both statements are true at the same time: illicit volume grows in dollar terms, but legitimate on-chain volume grows faster. As a result, the percentage share falls over the years while the absolute amounts rise. That distinction matters for how the headline should be read: the record describes the size of the illicit market, while the sub-1% share describes its weight relative to overall on-chain activity.

Two independent providers back the same order of magnitude. Chainalysis arrives at USD 154 billion for 2025 in its Crypto Crime Report 2026, and TRM Labs likewise at USD 158 billion. Both measure year-over-year growth of roughly 145% to 162%. The share of attributed transaction volume remains below 1% at Chainalysis and at 1.2% at TRM Labs. Although the two firms use different denominators and methods, the results match in scale.

The estimates are lower bounds by nature. Besides the 2024 revision, Chainalysis also revised its 2023 figure upward to USD 46.1 billion, or 0.61% of total volume. Analysts keep identifying new illicit addresses, so published values tend to rise over time. The 2025 figures from both firms should thus be read as provisional floors rather than final counts. For institutional observers, the overall finding therefore stays stable: in proportional terms, crypto is a fringe phenomenon of global crime.

Sanctioned Actors Drive Volume to USD 104 Billion

The rise to USD 154 billion does not stem from ordinary crime or retail fraud. Instead, sanctioned actors received around USD 104 billion in 2025, an increase of 694% from the prior year. State-linked sanctions evasion is by far the largest driver of the overall increase, and the growth is concentrated in designated state-linked entities rather than in the ordinary-crime and retail-fraud categories.

Russia delivers the biggest single contribution. The ruble-backed stablecoin A7A5, launched in February 2025, processed USD 93.3 billion in less than ten months. A single vehicle thus bundled a substantial portion of sanctions-related volume.

Iran's crypto sector also reached a notable USD 7.78 billion in 2025. Addresses linked to the Islamic Revolutionary Guard Corps (IRGC) alone moved more than USD 3 billion, and in the fourth quarter of 2025 they accounted for over 50% of all recorded Iranian entity value. The shift toward state actors changes the threat picture, but it does not confirm the image of the anonymous lone offender. Because attribution to designated entities relies on the same address-identification work described above, these sanctions-related totals, too, are likely to rise in future revisions.

Stablecoins Displace Bitcoin as the Criminal Asset of Choice

The finding strikes at the core of the old myth. Stablecoins made up around 84% of total illicit transaction volume in 2025, while Bitcoin, long labeled the criminal currency, now plays only a minor role.

The shift follows practical considerations rather than a desire for anonymity. Stablecoins suit fast cross-border payments and hold a stable value. Yet this preferred asset is also the easiest to seize: issuers such as Tether and Circle can freeze balances, whereas Bitcoin transactions remain immutable once confirmed. That combination — the asset class dominating illicit flows also being the most directly freezeable — is central to the current enforcement picture.

The industrial organization of the activity shows in Chinese-language money laundering networks. These so-called CMLNs processed around USD 16.1 billion in 2025 across roughly 1,799 active wallets. That amounts to about USD 44 million per day and roughly 20% of globally identified money laundering activity. Bitcoin, in any case, offers no anonymity, since every transaction stays visible on the public ledger.

Public Ledger Makes Crypto Assets Traceable for Investigators

Traceability reverses the crime narrative. Every crypto transaction is permanently recorded on a public ledger, and every wallet address leaves a traceable trail. Cash offers investigators no such advantage. That same public record is also what makes the estimates above possible: firms such as Chainalysis and TRM Labs derive their figures from on-chain attribution.

Law enforcement increasingly uses this fact. US authorities seized more than USD 15 billion in fraud proceeds in 2025, most of it in a single case: the US Justice Department's civil forfeiture from October 2025 targeting around 127,271 Bitcoin. The coins, worth about USD 15 billion at the time, were tied to the Prince Group around Chen Zhi, making it the largest asset seizure in the department's history.

The approach is not new. The 2016 Bitfinex hack stole 119,756 Bitcoin, then worth around USD 72 million. Thanks to blockchain forensics, investigators cracked the case in 2022 and secured around USD billion in assets in the proceedings against Ilya Lichtenstein and Heather Morgan.

The scale relativizes the figures further. According to the UNODC, money laundered annually through traditional financial channels reaches USD 800 billion to USD 2 trillion. The entire illicit crypto volume of USD 154 billion remains a fraction of what the traditional financial system processes each year. Future report editions will revise the 2025 totals upward as attribution work continues, and the proportional share alongside the absolute record will remain the pairing to track in those revisions.
