Turkish authorities have intensified their crackdown on illegal online betting and money laundering by freezing hundreds of millions of dollars in crypto-linked assets, highlighting the growing role of stablecoin issuers in global law enforcement actions.
At the center of the move is a €460 million ($544 million) asset freeze tied to Veysel Sahin, a fugitive accused of running illicit betting networks and laundering their proceeds, according to Bloomberg. Prosecutors in Istanbul confirmed that the freeze was executed with the assistance of a crypto company, which was later identified as Tether Holdings SA, the issuer of the world’s largest stablecoin, USDT.
The action forms part of a broader enforcement push in Turkey, where authorities say more than $1 billion in assets have already been seized in recent operations targeting illegal gambling and financial crimes. Days after the Sahin case became public, local media reported that an additional $500 million in cryptoassets linked to a separate investigation had also been frozen, underscoring the scale of the campaign.
For Tether, the episode reflects a clear shift in posture. Once viewed skeptically by regulators, the stablecoin giant has increasingly positioned itself as an active partner to governments and law enforcement agencies.
The company says it responds to formal legal requests by reviewing evidence and taking action in line with local laws, a stance echoed by CEO Paolo Ardoino, who has emphasized cooperation with authorities ranging from national prosecutors to U.S. federal agencies.
This more hands-on approach mirrors a broader trend across the stablecoin sector. Blockchain analytics firms report a sharp rise in wallet blacklisting over the past two years, with billions of dollars’ worth of tokens frozen as issuers intervene more aggressively against suspected criminal use. USDT accounts for the majority of these actions, reflecting both its global reach and its prominence in cross-border transactions.
Despite the increased collaboration, scrutiny remains. Law enforcement agencies continue to flag USDT as a favored tool in large-scale money laundering cases, and researchers have pointed to its use in sanction-evasion strategies by state-linked actors. These concerns persist even as Tether highlights its expanding compliance efforts and its return to closer engagement with U.S. regulators.
In Turkey’s case, officials say more seizures should be expected as investigators continue to trace illicit financial flows through both traditional channels and cryptoassets. The Sahin freeze, they argue, sends a clear signal: digital assets are no longer beyond the reach of state enforcement, and cooperation from major stablecoin issuers is becoming a key lever in that effort.
