Sihanoukville Casinos Took $1.07B in Crypto on Tron, TRM Labs Says

Blockchain analytics firm TRM Labs says 34 in-person casinos in Sihanoukville took in roughly $1.07 billion in cryptocurrency between January and early September 2026, almost all of it USDT on the Tron blockchain. The figure matters for players across Southeast Asia who use stablecoin rails to deposit, and it sharpens the next round of regulatory questions for every crypto casino that touches the region.

What TRM Labs actually counted

TRM’s research note, cited in reports by Cambodia Investment Review and Cambojanews on November 5, 2026, tracked stablecoin flows to on-chain wallets the firm had previously attributed to 34 identified Sihanoukville casinos. The methodology measures transfers to wallets linked to those venues. It is not a measure of casino revenue, and TRM has stated that the figure does not prove every transaction involved criminal proceeds.

The headline number, $1.07 billion, is the gross value received by those wallet clusters during the first nine months of this year. According to TRM’s blog, USDT on Tron accounted for 99.9% of the inflows. Other chains made up the remainder and were, in the researchers’ words, a rounding error in this data set.

The sanctions overlap is the real story

About $687 million, or 64% of the total, reached casinos TRM associates with networks sanctioned by the US Treasury’s Office of Foreign Assets Control. More than $320 million of that landed at three of those casinos after sanctions on their parent networks took effect, according to the TokenPost summary of the report. That is the line enforcement agencies will look at hardest.

The flows trend downward across the period. Monthly inflows averaged about $148 million from January through May, then dropped to roughly $95 million in July and August as Cambodian authorities moved against the Sihanoukville corridor. TRM cautions that some operators may have shifted to wallets the firm has not yet attributed, so the apparent slowdown could be partly a measurement artefact rather than a real volume decline.

Why this reaches players in Southeast Asia

Sihanoukville’s crypto-receiving casinos are largely offshore operations targeting mainland Chinese and Southeast Asian players who are blocked from licensed domestic markets. Those players deposit via USDT on Tron because fees are low and transfers typically settle in under a minute. The same convenience that makes the rail attractive to players is what makes the money flow legible on a public blockchain, which is why firms like TRM can trace it at all.

For players in Malaysia, Singapore and Thailand, the practical takeaway is specific: depositing into a Sihanoukville-linked casino with USDT puts your on-chain history next to wallets that have been named in US sanctions reporting and in Cambodian enforcement actions. That is a different risk profile from depositing with a licensed operator in a regulated market, and the risk does not vanish when the flows move to a new, unattributed wallet.

If you are in Malaysia, Singapore or Thailand and have ever topped up a casino wallet with USDT on Tron, do you know whether the receiving address was one of the ones TRM flagged?

Where enforcement goes next

Cambodia’s Financial Intelligence Unit and the National Bank have both signalled tighter oversight of casino-linked virtual asset flows, and the TRM figures will give that work a specific target list. The report’s existence also strengthens the US Treasury’s hand in any new OFAC action against the Sihanoukville operators that remain outside the already-sanctioned perimeter.
