While headlines swirl around Maria Bartiromo — from her Fox Business exclusives to political intrigue involving former President Donald Trump — there’s one person who consistently stays out of the spotlight: her husband, Jonathan Steinberg. Reserved, wealthy, and quietly influential, Steinberg is a force in the financial world and the longtime partner of one of TV’s most recognizable faces.
A Surprising Political Connection
Recent revelations from Politico reporter Alex Isenstadt’s book Revenge claim that Bartiromo was seriously considered as Trump’s running mate for 2024. Though the political winds shifted, the news turned attention not just to Bartiromo, but also to the man who’s been by her side for over two decades — someone with his own towering legacy in finance.
A Wall Street Name with His Own Climb
Jonathan Steinberg isn’t new to the financial world. He’s the son of Saul Steinberg, the renowned Wall Street dealmaker known for bold takeover attempts of corporate giants like Disney and Chemical Bank in the 1980s. Growing up under such a figure might have promised an easy ride, but Jonathan’s journey was anything but.
After enrolling at the University of Pennsylvania’s Wharton School, he faced academic challenges and didn’t complete his degree. Instead of following a traditional path, Steinberg chose to blaze his own trail — one that would lead him to helm a multibillion-dollar enterprise.
Building WisdomTree from the Ground Up
In 1988, Steinberg launched WisdomTree, a New York-based firm that started small but gradually became a formidable name in the ETF (exchange-traded funds) market. Competing with major players like BlackRock and Vanguard, WisdomTree’s growth reflects Steinberg’s strategic mind and willingness to innovate.
His efforts didn’t go unnoticed. In 2015, Ernst & Young named him Entrepreneur of the Year in New York — a mark of high respect in business circles. Today, Steinberg’s estimated net worth sits around $94 million, and his firm manages billions globally. With ongoing expansion into blockchain and digital finance, his influence shows no sign of fading.
A Low-Key, High-Powered Partnership
Jonathan met Maria Bartiromo in 1990, when she had just graduated from NYU. They married nine years later in Quogue, a quiet yet upscale enclave in the Hamptons. Over the years, they’ve built a solid, private life far from the media frenzy often surrounding high-profile couples.
They share a luxurious Manhattan townhouse and retreat to their Westhampton beach home on weekends. Despite their public personas, friends describe the couple as deeply respectful of one another, aligned in values, and quietly ambitious.
The Strategist Who Avoids the Spotlight
Unlike his outspoken wife, Steinberg prefers a background role. He rarely appears in the media and avoids public events, opting to focus on business. Those who’ve worked closely with him speak of a determined thinker with a sharp mind and understated charisma.
His long-term goal? To take WisdomTree past the $100 billion mark in assets under management — a move that would cement the firm’s position among Wall Street’s elite. With fresh investments in crypto-focused products and fintech innovation, that milestone might be within reach.
The Hidden Strength Behind a Media Icon
While Bartiromo continues to make waves in media and politics, Steinberg remains her steadfast supporter — shaping markets quietly, far from the cameras. Together, they represent a rare kind of partnership: influential yet private, powerful yet grounded.
In the noisy intersection of finance, media, and politics, Jonathan Steinberg is the quiet engine driving forward — and perhaps the key to understanding the full story behind one of America’s most watched financial journalists.
