Siebert Financial Names David and Richard Gebbia Co-CEOs as John J. Gebbia Becomes Chairman

Siebert Financial is placing its next phase of leadership in the hands of two generations of the Gebbia family. Brothers David and Richard Gebbia will become co-chief executive officers, while their father, John J. Gebbia, shifts to board chairman. The change keeps him involved in strategic oversight as the brothers take responsibility for the company’s overall strategy, business development and expansion.

The appointments also give John M. Gebbia a leadership role at the operating level. He was named chief executive of Muriel Siebert & Co., Siebert Financial’s main broker-dealer subsidiary, and will join the parent company’s board of directors. His remit includes running the brokerage operations, connecting the subsidiary’s management with governance at the parent company.

A broader remit for the co-CEOs

David and Richard Gebbia are expected to guide a business that now spans more than brokerage. Siebert offers wealth management, investment banking, securities lending and financial technology, among other services. Their stated priorities include widening the range of financial services, forming strategic partnerships, developing new products and spending on technology.

Those priorities describe a growth agenda across several parts of the business, rather than a focus on one product line. Expanding services can create more ways to serve clients, while also requiring attention to how new offerings fit with existing operations. Partnerships, product development and technology spending likewise call for choices about where the company sees room to build. The source provides no budget, timetable or revenue targets for these plans, so their scale and pace remain unclear.

John J. Gebbia will remain engaged as chairman, providing strategic direction and oversight. That arrangement preserves his role in the company’s leadership while assigning the co-CEOs the broader executive brief. For the business, the practical test will be how responsibilities are divided and how the leadership team turns its stated priorities into operating decisions.

Revenue and areas of activity

Siebert reported $31.2 million in revenue for the second quarter of 2026. The company attributed the result to its stock borrow and stock loan, investment banking, wealth management and advisory units. The figure offers a snapshot of a business with revenue sources across several activities, though the source does not provide comparisons with earlier periods or a breakdown by unit.

That missing detail limits what can be inferred from the total. Without segment figures or period comparisons, readers can’t tell which activities contributed the most, how their performance changed, or how much each supported the reported revenue. The company’s breadth helps explain why the co-CEOs’ remit covers both products and expansion, but the available figures don’t establish how that strategy has performed.

Siebert has also been building tools for tokenized securities, cross-border market access and new investment products. These efforts point to areas the company is pursuing alongside its established financial services. The source does not specify launch dates, customer adoption or expected financial contribution. For now, the concrete measure in the account is the second-quarter revenue figure; progress in newer areas will depend on what the company develops and how those offerings contribute to its operations.

A family-led succession

The Gebbia family has led Siebert since 2016. John J. Gebbia framed the transition as part of a longer commitment to the company, saying: “This company has always been built for the long term from its start almost 60 years ago. Our family is committed to Siebert and the next 60 years, and I’m proud to continue working alongside my sons as we build the next chapter together.”

Richard Gebbia said the brothers had prepared for the responsibility: “We know this business, we know where the opportunities are, and we have a clear plan to keep growing. We have been preparing for this task for decades now, and have the right experience and ambition to achieve it.” David Gebbia described the family’s approach this way: “Our belief is that every generation has a responsibility to leave the business stronger than they found it, taking key decisions together as a family to shape its future.”

The family’s stewardship is set against a company history that began with Muriel “Mickie” Siebert. In 1967, she became the first woman to hold a seat on the New York Stock Exchange and later the first to head one of its member firms. Siebert will mark its 60th anniversary in 2027.

The transition places the company’s stated expansion priorities with the co-CEOs while retaining John J. Gebbia’s guidance and adding John M. Gebbia to the subsidiary’s leadership and the parent board. How that structure supports the firm’s varied business lines—and whether technology and product initiatives add to the revenue base—will be central measures of the next phase.
