Across the most recent 1 story covering Siavash Kayvanpour — 100% negative sentiment, averaging 7/10 impact.
This entity profile aggregates every story where the entity meets our minimum relevance threshold before it is linked here — a story naming this entity only in passing, as competitive context for an unrelated subject, does not qualify. That threshold exists because earlier testing surfaced entity pages cluttered with tangential mentions: a story about two unrelated companies merging could otherwise populate a third company's page simply because it was named once for comparison, with no real event of its own. The timeline below reflects genuine milestones and developments specific to this entity, cross-referenced against the same source-verification standard applied to every story on this site. Sentiment measures the directional read of each development for this entity specifically, not the overall tone of the reporting, and impact weights how consequential a development is rather than how widely it was syndicated across outlets.
Figures are computed live from our source-verified story record — see our methodology for how impact and sentiment are derived.
U.S. Treasury sanctions Shelbit, Kayvanpour, and Aban Tether
OFAC designated the Dubai exchange, its founder, and the Iran-based exchange for providing material support to the IRGC and other designated entities.
Shelbit website reactivated and denial issued
Shelbit’s previously dormant website went back online; the exchange issued a statement denying knowing involvement in money laundering or sanctions evasion.
Reuters investigation published
A Reuters report identified Shelbit as the hub of a $4 billion Iranian sanctions evasion network, detailing flows from bitcoin mining and gambling operations.
Nobitex designated by OFAC
The U.S. Treasury sanctioned Nobitex for enabling Iranian sanctions evasion, following a Reuters investigation.
Shelbit claimed cessation of operations
Shelbit later stated it ceased operations in January 2026, though the Treasury alleges activity continued.
The U.S. Treasury’s sanctions on Dubai-based Shelbit and founder Siavash Kayvanpour mark a significant legal escalation, building on a Reuters probe and targeting IRGC-linked money laundering. The actions highlight expanding OFAC authority over crypto exchanges and raise questions about founder liability and jurisdictional reach.
This page surfaces every story mentioning Siavash Kayvanpour across our legal coverage. We track each entity's appearance over time so readers can trace how the narrative evolves — which developments are isolated incidents, which build into longer arcs, and which reframe how operators in the space think about the entity. Story selection uses the same multi-source verification gate applied across the rest of our coverage.
Read our editorial methodology for how we identify, deduplicate, and score entity references. Our glossary defines the technical terms used across stories on this page, and our trends index contextualizes individual developments against the longer-running legal beat. Cross-entity comparisons live on our compare view.
Entities only appear on this page once the classifier scores them at a minimum 35 percent relevance to the story, filtering out passing mentions. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
