Maria Bartiromo Husband Net Worth: How to Estimate It

Maria Bartiromo's husband is Jonathan Steinberg, founder and CEO of WisdomTree, Inc. (NYSE: WT), a publicly traded asset management company he has led since October 1988. Based on his disclosed executive compensation, equity holdings, and WisdomTree's public market valuation, a credible estimate of Jonathan Steinberg's net worth lands somewhere in the range of $50 million to $150 million, with $75 million to $100 million being the most defensible middle estimate given what's verifiable in SEC filings and insider ownership data.

Who is Jonathan Steinberg?

Jonathan Steinberg has been building financial companies since the late 1980s. Before WisdomTree, he founded and served as Chairman and CEO of Individual Investor Group, Inc., a media and financial information company. He then channeled that experience into building WisdomTree, which he founded and has run as Chief Executive Officer continuously since October 1988. WisdomTree is best known for launching exchange-traded funds (ETFs) built around dividend-weighted and fundamentals-based indexing strategies. As of 2025, the company manages tens of billions of dollars in assets globally and is a legitimate mid-cap publicly traded firm.

He and Maria Bartiromo married in 1999. Maria, of course, is the Fox Business anchor and financial journalist who became famous as the first reporter to broadcast live from the floor of the New York Stock Exchange. So this is genuinely a power couple in the financial media and asset management world, not just a celebrity pairing.

Jonathan Steinberg's net worth: the range and the most likely number

Because WisdomTree is a public company, we have more financial transparency on Steinberg than you'd get with a purely private operator. That said, net worth is still an estimate because private assets, real estate holdings, and liquid investments outside of disclosed equity aren't fully public. Here's how the range breaks down:

The WisdomTree equity stake is the single biggest driver of any Steinberg net worth estimate. As founder and long-tenured CEO, he holds a meaningful beneficial ownership position that is disclosed in WisdomTree's annual proxy statements (DEF 14A filings with the SEC). The actual dollar value of that stake moves with WT's share price, which has experienced significant volatility over the years. This is why you'll see a wide range in third-party estimates of his wealth: they're often capturing the stock at different points in time.

Where the wealth comes from: career earnings and asset signals

Executive compensation at WisdomTree

WisdomTree's proxy statements (filed each spring as DEF 14A documents with the SEC) disclose Jonathan Steinberg's annual compensation in the Summary Compensation Table. The 2024 proxy filing covers his 2023 pay, and the 2025 proxy covers 2024. These filings break out base salary, cash incentive awards, and equity-based compensation. For a CEO of a publicly traded asset manager of WisdomTree's size, total annual compensation packages in the range of $3 million to $8 million (including equity grants) are typical, and Steinberg has been drawing executive pay at this company for over 35 years. That's a long runway of salary and bonus accumulation, even before you factor in equity upside.

Equity ownership and insider holdings

The most significant wealth signal for a founder-CEO of a public company is their stock ownership. WisdomTree's proxy statements include a beneficial ownership table that lists exactly how many shares Steinberg holds (directly and indirectly). You can cross-reference this against WT's current share price on any given day to get a real-time estimate of that portion of his net worth. Third-party insider ownership trackers, like the one provided by Simply Wall St and similar services, aggregate this data from SEC filings and make it easier to read. But always check the primary SEC filing for accuracy.

Prior business ventures

Before WisdomTree, Steinberg built Individual Investor Group, a financial media company. While that business didn't produce the kind of exit that made him a billionaire, it demonstrated his pattern of building financial information and services companies from scratch. That operational experience translated directly into WisdomTree's ETF strategy, and it's worth noting that the wealth picture isn't just about one company: it's about a career-long pattern of building equity in entrepreneurial financial ventures.

How net worth estimates are calculated (and why they vary so much)

When you see a celebrity net worth figure, it's almost always an estimate built from public signals, not verified bank statements. For someone like Jonathan Steinberg, the methodology typically works like this:

1. Pull disclosed compensation from SEC proxy filings (salary, bonuses, equity awards) and annualize over known tenure
2. Find the beneficial ownership section in the most recent proxy to quantify the equity stake
3. Multiply shares held by current market price to estimate the value of public equity
4. Apply a discount for illiquidity or concentrated positions (founders often can't easily sell all their shares)
5. Add rough estimates for real estate, private investments, and other assets based on public records or lifestyle signals
6. Subtract any known or estimated liabilities

The reason estimates vary so widely, sometimes by tens of millions of dollars, comes down to timing and assumptions. A site that pulled WisdomTree's stock price in 2021 (when ETF stocks were trading at highs) would show a very different equity value than one pulling it in 2023 or 2024. Private assets are essentially guesswork unless someone discloses them. And different sources use different methodologies for estimating accumulated compensation. So when you see a figure like '$50 million' or '$150 million' from different sites, they're not necessarily wrong; they may just be capturing different moments or making different assumptions about private holdings.

How their careers shape the household financial picture

Maria Bartiromo is herself a high earner. If you are also looking for Maria's financial backstory, this includes the reporting on the barbara corcoran husband net worth topic and how similar wealth estimates are built Maria Bartiromo's husband. Her salary at Fox Business is estimated by multiple sources to be in the range of $10 million to $20 million annually, and she's built a career spanning more than three decades in financial journalism, including stints at CNBC and her current Fox Business role. She's also authored several books. Her individual net worth is frequently cited in the $20 million to $30 million range, though combined household wealth when you include Steinberg's stake in WisdomTree is meaningfully higher. When estimating Maria Brisbane husband net worth, most calculations focus on Jonathan Steinberg’s long-tenured WisdomTree equity stake. Because Maria Bartiromo is married to Jonathan Steinberg, their combined household wealth is closely tied to bangs garcia husband net worth estimates and WisdomTree share price swings. Kris Bernal’s husband’s net worth is often discussed alongside other household income and assets, but the most reliable figures depend on what is publicly documented. Some people also look for figures like Barry Gibb net worth and his wife to compare how celebrity and spousal income shape household finances combined household wealth.

What's interesting about this couple from a financial dynamics standpoint is that they represent two different models of wealth building: Maria's is income-driven (salary, brand, media presence) while Jonathan's is equity-driven (founder stakes, long-term company ownership). That combination, one partner accumulating liquid income and the other accumulating illiquid equity, is actually quite common among high-net-worth couples in the finance and media worlds. You see similar dynamics in other notable pairings where one partner runs a business and the other generates significant earned income. The household's actual financial flexibility depends a lot on how liquid Steinberg's WisdomTree position is at any given point.

How to verify the numbers and where to watch for updates

If you want to verify Jonathan Steinberg's compensation and equity stake yourself (and you should, if precision matters to you), here are the exact places to look:

• SEC EDGAR (edgar.sec.gov): Search for WisdomTree, Inc. (ticker: WT) and pull the most recent DEF 14A (proxy statement). The Summary Compensation Table will show Steinberg's annual pay. The beneficial ownership table will show his share count.
• WisdomTree Investor Relations page: Direct link to SEC filings including the 2025 proxy (filed April 29, 2025) and the most recent 10-K, which contains the annual report and additional compensation disclosures.
• WisdomTree's stock price: Check WT's current share price on any financial data site (Google Finance, Yahoo Finance, Bloomberg) and multiply by the share count from the proxy for a real-time equity estimate.
• Third-party insider tracking tools: Sites like Simply Wall St aggregate insider ownership data from SEC filings and make it easier to monitor, but always cross-check against the primary SEC source.
• Annual proxy filing cycle: WisdomTree typically files its proxy statement in late April each year, covering the prior fiscal year's compensation. The 2025 proxy (April 2025) is the most current as of mid-2026, with the 2026 proxy expected around April 2026.

For tracking net worth changes over time, the key variable to watch is WisdomTree's share price and any changes in Steinberg's beneficial ownership (which can change due to stock sales, grants vesting, or other transactions, all of which are disclosed in Form 4 filings with the SEC within two business days of the transaction). If WisdomTree's stock moves significantly, Steinberg's estimated net worth moves with it. That's the nature of founder-equity wealth.

Bottom line: Jonathan Steinberg is a legitimate finance industry executive with a verifiable, publicly documented financial footprint. His net worth is best understood as founder-equity-driven, SEC-trackable, and meaningfully in the eight-figure range, most likely somewhere between $75 million and $100 million based on available 2025 data. That figure could shift materially depending on WisdomTree's stock performance, so treat any static number as a snapshot rather than a fixed truth.
