BRYANT EDWIN SEWALL, (D. Colo.)

Defendant - Appellant.

ORDER AND JUDGMENT *

Before BACHARACH, McHUGH, and ROSSMAN, Circuit Judges.

A jury convicted Appellant Bryant Edwin Sewall of fourteen counts of wire fraud and one count of conspiracy to commit wire fraud. He now appeals that conviction. We have jurisdiction under 28 U.S.C. § 1291, and we affirm. I. BACKGROUND In late 2015, Mr. Sewall became one of three partners in a company called Mediatrix. Beginning in March 2016, Mediatrix accepted money from clients and

unanimously to honor the parties’ request for a decision on the briefs without oral argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.

invested it in the foreign currency exchange (forex) market. Mr. Sewall’s partners were Michael Stewart and Michael Young. Mr. Young’s primary role was marketing, i.e., bringing in new investors. Mr. Stewart’s primary role was operations (e.g., managing banking relationships), but he also participated to some degree in marketing. Mr. Sewall’s primary role was trading, especially through a proprietary algorithm he developed.

To actually send trades to the market, Mediatrix worked through a specialized broker named Divisa, later named Equiti. As will become important below, Equiti would not necessarily execute every requested trade. It imposed limits on how large of a position a client could take within a given amount of time, and it would reject trades that exceeded those limits.

Mediatrix made money by taking a percentage of the upside when it made a profitable trade. On top of that, Messrs. Sewall, Stewart, and Young established a brokerage named Blue Isle to hold client funds, and that brokerage charged a small markup on every trade, whether winning or losing. Messrs. Sewall, Stewart, and Young therefore profited both through Mediatrix’s cut of the winning trades and Blue Isle’s markups. For purposes of this order and judgment, we will refer to Mediatrix and Blue Isle collectively as “Mediatrix.”

In September 2019, the Securities and Exchange Commission (SEC) froze Mediatrix’s assets on suspicion of fraud. In February 2021, a grand jury indicted Mr. Sewall (along with Mr. Stewart) on the wire fraud and conspiracy counts previously mentioned. In a separate action, Mr. Young pleaded guilty to one count of

lying to the SEC 1 and agreed to testify on the government’s behalf in the case against Mr. Sewall and Mr. Stewart.

A jury heard Mr. Sewall’s and Mr. Stewart’s case in May 2024. The trial lasted twelve days and included more than thirty witnesses. The government presented evidence that Mediatrix brought in about $129 million in client funds between March 2016 and September 2019 (when the SEC shut it down). But falsehoods continually infected Mediatrix’s marketing pitches and materials, particularly the claim that the trading algorithm (i.e., Mr. Sewall’s algorithm) had never had a losing month. In truth, Mediatrix frequently had losing months.

Mediatrix kept its losses hidden from clients because client statements only showed the profit or loss of closed trades, a.k.a. “closed P&L.” The clients were not told about open trades, most of which were trending downward and would someday need to be closed at a loss unless the market happened to turn around. In other words, clients were blind to the “floating P&L,” so named because the profit or loss continually changed as the market fluctuated. Such a system allows a forex trader, such as Mr. Sewall, to

be a loss of $250,000 that is floating and getting that much worse for their account that they would have no idea.

R. vol. VII at 2051.

Touting its record of consistently profitable closed trades, without disclosing outstanding liabilities, Mediatrix continually claimed to clients and prospective clients that the company had never had a losing month. This induced some prospective clients to invest, and some current clients to invest more. This was the ultimate basis for the wire fraud charges, i.e., using false pretenses to induce investors to wire money to Mediatrix.

Mediatrix’s system of reporting only profitable trades without disclosing floating losses led to an ever-widening gap between what clients saw when they checked their account balances and what Mediatrix could pay if clients chose to withdraw some or all of that balance. When Mediatrix shut down, clients’ purported account balances added up to almost $180 million but the company had a little less than $10 million in assets, and the cumulative floating P&L was negative $33.2 million. Nonetheless, over the course of Mediatrix’s existence, Messrs. Sewall, Stewart, and Young earned $24 million in performance fees—the upside percentage Mediatrix took on purportedly profitable trades—and $45 million in markup revenue.

Mr. Young testified on the government’s behalf. He claimed he did not know about Mediatrix’s true financial condition, but instead pitched potential investors using the information Mr. Stewart and Mr. Sewall gave to him. Mr. Stewart testified on his own behalf. He admitted Mediatrix had been a failure but claimed it was the

product of poor business judgment and misplaced trust, not deceit. Mr. Sewall did not testify.

The jury convicted on all counts. The district court later sentenced Mr. Sewall to 276 months’ imprisonment and ordered him to pay more than $93 million in restitution. 2 We will provide more details as they become relevant to Mr. Sewall’s arguments, discussed below. II. ANALYSIS Mr. Sewall challenges: (i) the exclusion of certain exhibits; (ii) the sufficiency of the evidence to convict him; and (iii) the district court’s decisions as to some of the jury instructions. We will first address the sufficiency of the evidence, because that discussion provides important context for the other two issues. We will then address the evidentiary exclusions and the jury instructions.

A. Sufficiency of the Evidence Mr. Sewall’s sufficiency challenge does not attack any particular count of the indictment. Instead, he argues the evidence was insufficient as to all counts for the same reason, namely, he never intended to defraud anyone. Cf. R. vol. III at 1287, 1290 (jury instructions for wire fraud and conspiracy, both requiring “specific intent to defraud”). Mr. Sewall asserts he had no meaningful contact with investors, his
