Beginning 2011, Siroochenko’s financial activity started appearing regularly in Epstein’s correspondence. Between 2011 and 2015, Black and entities linked to him transferred at least $2.5 million to her personal accounts.
Accountants classified the payments as gifts, according to the emails, which show Epstein coordinating how the transfers were documented and described for tax and audit purposes.
In 2013, Siroochenko founded Sublime Art LLC, an art dealer and consulting company, and according to records, Black became a client of the firm, with invoices reflecting hundreds of thousands of dollars in art purchases.
Separate correspondence from 2017 describes a proposed commission agreement between Sublime Art and Narrows Holding LLC, a company associated with Leon Black. According to the Epstein files, Narrows held art owned by Black as collateral, and accounted for the vast majority of the loans tied to his art portfolio as of 2016, Forbes reported.
Under the 2017 agreement, Siroochenko’s company would receive $1.8 million for arranging the sale of a Paul Klee painting valued at $7.8 million, contingent on the completion of the sale. Epstein appears in the emails approving language and relaying information among parties, though the records do not establish whether the commission was ultimately paid.
The overlap between Siroochenko’s personal income from Black and her business dealings with him prompted concern among some accountants and auditors involved in her finances. In one email, an accountant warned that the arrangement could present a conflict of interest, noting that the gift deposits clearly identified Black as the source of funds while he was also the firm’s principal client.
Other correspondence shows disputes over property purchase in Lviv, Ukraine. One accountant later resigned, citing disagreements over the ownership and tax treatment of the Lviv property, according to the emails. Those also indicate that funds used to purchase the property were transferred from Siroochenko’s personal account to an limited liability company and categorized as a loan, and part of those funds was used to buy the property. Public records list her as the owner as of 2026.
The emails suggest Epstein took interest in ensuring that documentation related to the property was handled correctly for reporting purposes.
Some messages also suggest that funds moving through Siroochenko’s companies were, at times, discussed in connection with potential investments involving Black’s interests. The records do not show that such transactions were completed, nor do they establish that he directed these discussions.
Black stepped down from leadership roles at Apollo Global Management Inc. in 2021 following renewed scrutiny of his relationship with Epstein. He has acknowledged relying on Epstein for financial advice but claimed he was unaware of Epstein’s criminal conduct. In the past, three women had accused Black of sexual assault; he has denied the allegations, and a federal lawsuit brought by a woman identified as Jane Doe remains pending.
The documents form part of a broader body of material illustrating Epstein’s financial dealings with Black and others. Previous investigations found that Black transferred millions of dollars to multiple women connected to Epstein, some of whom were later identified in court filings as victims or associates of the convicted sex offender.
In a written response, Siroochenko said that her name “appears in the disclosed correspondence solely in connection with private financial, property, and legal matters from nearly a decade ago and has no connection to any criminal cases. References to me in the correspondence were strictly of a business nature.”
Siroochenko said she has worked in the international art field for many years and that her “professional activity has always been public and transparent” and that she has never been a subject of any criminal proceedings.
While the newly released records do not explain the purpose of the transfers to Siroochenko or establish illegality, they provide a detailed record of how Epstein embedded himself in financial relationships that blended personal payments, business transactions and tax planning — arrangements that, in some cases, unsettled professional advisers but nonetheless continued for years.
The files leave unresolved why such large sums changed hands and why Epstein played such an important coordinating role. But they add to the public record of how Epstein exercised influence far beyond his own finances, operating in ways that often relied on discretion, complexity and limited transparency.
