Before Celebrating Big Gifts, Charities Must Watch Out for Fake Donors

A New York philanthropist and personal assistant to billionaires, Matthew Christopher Pietras, allegedly stole millions from his employers and donated large sums to prominent charities to maintain a facade of status, wealth and generosity.

Those schemes came to light when the Metropolitan Opera became aware that a US$10 million donation Pietras made in his own name used funds he had allegedly pilfered from a member of the Soros family which was among his employers.

The next day, May 30, 2025, Pietras was found dead. An investigation into the origin of his donations is underway.

The 40-year-old belonged to many prominent nonprofit boards, attended galas, rubbed shoulders with elite donors, and lived a lavish lifestyle filled with luxury goods and private plane travel. He often made charitable gifts under his own name, and he frequently requested public recognition for them – a practice that helped build his persona.

I research nonprofit fraud. Previously, I’ve written about the importance of researching charities before donating to make sure charitable gifts are not wasted on swindlers. The Pietras case exposes the flip side of donor fraud.

Sometimes, people give stolen funds or find other fraudulent means to pretend to give their own money to a legitimate charity. This cautionary tale can remind nonprofits of the importance of checking out any donors who make large or unusual gifts.

What happens after the fraud is exposed

If Pietras’ crimes are proven, the Metropolitan Opera, Manhattan’s Frick Collection and the other charities that received money from Pietras will most likely have to issue refunds to the people he swindled. Even if the charity was acting in good faith, it should prepare to return those funds, according to laws that pertain to fraudulent transfers.

There is a narrow exception to this rule.

When a charitable nonprofit unwittingly accepts a donation made with stolen money and spends it before the theft is discovered, a court may recognize the charity as an innocent recipient.

In legal terms, this is known as the “good faith purchaser” defense.

This recognition may limit or eliminate the charity’s legal obligation to issue a refund, particularly if the money has already been spent on the charity’s mission, the organization reasonably believed the donation was legitimate, and giving it back to the victim of theft could significantly harm the charity.

But if that happens, fraudsters can’t claim a tax deduction for making that gift, and they may retroactively owe extra tax penalties.

If a charity hasn’t yet spent the fraudulently given funds, a court could require a refund – especially if victims or insurers file lawsuits to recover that money.

In most cases, if donations are proven to come from stolen funds, the charity may be legally required to return them. The fact that a donation was received in good faith doesn’t automatically allow the charity to keep the money once it is identified as stolen.

How snookered charities should respond

It is often in a charity’s best interest to be proactive about returning the stolen funds rather than awaiting a court order forcing them to do so.

The Metropolitan Opera took this route. It returned the $10 million to Gregory Soros, the youngest son of billionaire investor and philanthropist George Soros, that it received the day before Pietras’ scheme was discovered.

Taking that step is a good look. But charities don’t really have a choice because they cannot quickly spend any funds that are identified as potentially stolen. Once they’re stuck in this legal limbo, nonprofits must hang onto the funds and await a legal resolution .

Some similarities with Madoff scandal

I believe that the Pietras case mirrors the Bernard Madoff scandal in that both men donated to charities to burnish their social status.

Madoff, the disgraced financier who died in prison in 2021, operated a massive Ponzi scheme that deceived his clients with too-high-to-be-true returns and then depleted their savings once it collapsed.

Madoff also used stolen funds to make large charitable donations through his family foundation. His philanthropy made his fake image as an ace investor appear legitimate and it expanded his access to the wealthy people he preyed upon.

As with Madoff, Pietras’ illusion of generosity allegedly became a tool for his deception, allowing him to move comfortably among the wealthy and well connected while avoiding getting caught.

Madoff defrauded investors of an estimated $50 billion to $64 billion. The 2008 revelations about his scheme’s shocking scale shook confidence in financial and charitable institutions.

In the aftermath, numerous nonprofits that had invested their own assets with Madoff either lost significant sums or were forced to return past donations as part of legal clawback efforts to compensate victims.

When being wary is warranted

Charities must exercise due diligence before accepting a gift. This means they have a duty to investigate any unusually large donations – such as one that’s the biggest they’ve ever received.

Regardless of a gift’s size, this duty also applies when a gift seems to be larger than the donor could be reasonably expected to afford.

Charities don’t need to act like banks or lenders, which are required to verify the financial assets of clients. But they should ask questions when the circumstances require. Acting in good faith requires charitable institutions to be reasonably certain that donated funds are not stolen.

In Pietras’ case, he reportedly began by donating sums that were small enough to not raise suspicion.

Too-good-to-be-true giving

The consequences of not exercising due diligence can be costly and embarrassing.

For example, consider what happened to Florida A&M University in May 2024, when it announced a record-breaking $237 million gift from Texas entrepreneur Gregory Gerami. The donation consisted of 14 million shares in Gerami’s privately held Batterson Farms Corp.

An investigation later determined that Gerami couldn’t afford to make that gift and that Florida A&M had failed to check into his finances. The university’s president and other top leaders were forced to resign in the embarrassing fallout.

Asking donors hard and even uncomfortable questions before celebrating any huge gift can help charities avoid the headaches that come with being deceived by fraudulent donations.

Thorough vetting at the outset ensures that a celebrated gift enhances the charity’s work without entangling it in future disputes or negative publicity from a fraudulent gift.
