Maria Bartiromo’s Husband Jonathan Steinberg Runs a Billion-Dollar Investment Firm

Table of Content Show

Maria Bartiromo has long stood at the intersection of high finance and television, known as much for her poise behind the anchor desk as for the headlines she’s helped shape. Born in Brooklyn and raised in the Dyker Heights neighborhood, Bartiromo began her career not in front of the camera but behind it—first as a producer at CNN Business News.

In 1993, she made the leap to CNBC, where she would spend the next two decades becoming one of the most recognized faces in financial journalism. At a time when few dared to mix glamour with market reporting, she did just that—and made history in the process.

Bartiromo was the first journalist to broadcast live from the floor of the New York Stock Exchange, a breakthrough that earned her the nickname “Money Honey,” along with two Emmy Awards and a place in television news history.

Her move to Fox in 2013 marked a shift not only in networks but in tone. While her early work was defined by an apolitical lens focused on Wall Street and global markets, her programming at Fox News and Fox Business became more closely associated with conservative politics.

Off-screen, Bartiromo has kept her private life largely outside the frame. She has been married to businessman Jonathan Steinberg for decades. In the sections ahead, we take a closer look at her husband, their marriage, and the life they’ve built together away from the set.

The Marriage of Maria Bartiromo and Jonathan Steinberg

Maria Bartiromo met Jonathan Steinberg in 1990, shortly after graduating from New York University. At the time, she was just beginning her career in journalism, and he was already emerging as a figure in finance. Their relationship grew alongside their careers—his rooted in investment, hers in financial media. They married in June 1999.

The wedding was held at the home of Steinberg’s father and stepmother, Gayfryd Steinberg, in Quogue, New York. Rabbi Peter J. Rubinstein officiated. Bartiromo, who was then a rising anchor at CNBC, chose to keep her name after the marriage. Her parents, Josephine and Vincent Bartiromo of Brooklyn, attended. Her father, now retired, had once owned the Rex Manor restaurant in Bay Ridge.

Steinberg was 34 at the time of the wedding and the founder and CEO of Individual Investor Group, a financial media company in Manhattan. His father, Saul P. Steinberg, was the chief executive of Reliance Group Holdings and a well-known corporate figure in New York. Saul also served as an overseer of Weill Medical College at Cornell and was a trustee at the University of Pennsylvania, where he chaired the board at the Wharton School.

Maria and Jonathan have no children but maintain homes in both Manhattan and the Hamptons. Their residence in Manhattan is a five-story townhouse on the Upper East Side. They also own a beach house in Westhampton, where they often spend time away from the spotlight.

Through periods of professional intensity and occasional controversy, their marriage has remained steady. In the financial world and in media circles, they’ve come to represent a quiet kind of power couple—one rooted less in spectacle and more in mutual regard and parallel ambition.

Who Is Maria Bartiromo’s Husband, Jonathan Steinberg?

Jonathan Laurence Steinberg occupies a space where pedigree meets performance. He is the son of the late Saul P. Steinberg, the corporate raider who once embodied the aggressive, deal-hungry ethos of 1980s Wall Street. Saul’s name was synonymous with boardroom warfare and high-stakes finance; his son, by contrast, has carved out a career defined by endurance and steady growth.

Jonathan is the CEO of WisdomTree Investments, an asset management firm specializing in exchange-traded products. Based in New York, WisdomTree is a quiet heavyweight in the field, competing alongside industry giants like BlackRock and Vanguard. Under Steinberg’s leadership, the firm has expanded its offerings and now manages billions in assets. His long-term goal is clear: to grow WisdomTree beyond $100 billion in assets under management.

Before founding WisdomTree, Steinberg led the Individual Investor Group, a financial media company. His early background in financial publishing gave him a direct window into the investing public’s mindset, an experience that would later inform WisdomTree’s data-driven, retail-friendly approach to investment strategy.

Despite being married to one of the most visible faces in financial media, Steinberg remains almost defiantly low-profile. He has never sought the spotlight, preferring performance over publicity. His reputation rests on business decisions, not headlines.

Together with Maria Bartiromo, he shares a partnership built on shared ambition and mutual respect. While her name may be more familiar to the public, Steinberg’s work is well-known within the circles that matter—portfolio managers, institutional investors, and financial analysts. In a world that rarely permits quiet success, Jonathan Steinberg has managed to build exactly that.
