Quick answer: David Baszucki's estimated net worth
As of March 2026, David Baszucki's net worth is estimated at approximately $5 to $6 billion USD. The most widely cited figure comes from Forbes, which pegged his net worth at $5.6 billion as of December 2025 and continues to maintain a real-time estimate on its billionaires tracker (last updated March 10, 2026). Bloomberg's Billionaires Index also tracks him daily with a dynamic calculation tied directly to Roblox's stock price. Treat any single figure as a snapshot: the actual number shifts every trading day because the vast majority of his wealth sits in Roblox equity, not cash.
| Source | Estimate | As of |
|---|
| Forbes Real-Time Net Worth | ~$5.6 billion | December 2025 / updated Mar 10, 2026 |
| Bloomberg Billionaires Index | Dynamic daily estimate | Updated continuously |
| GuruFocus (insider holdings basis) | "At least" threshold figure | March 12, 2026 |
The honest range to use when researching Baszucki is roughly $4.5 billion on the low end (reflecting periods when Roblox stock has traded lower) to $6.5 billion on the high end (reflecting stronger market performance). Different trackers will give you slightly different numbers depending on which share count they use, how they value unvested equity, and how recently they updated their data.
How the estimate is actually built
Baszucki's net worth is almost entirely a function of one variable: Roblox Corporation's stock price multiplied by his ownership stake. Roblox went public via a direct listing on the New York Stock Exchange in March 2021 under the ticker RBLX. That event converted years of private equity into publicly priced shares and gave trackers like Forbes and Bloomberg a transparent, real-time basis for calculating his wealth.
Here is how the math works in practice. Baszucki holds a combination of Class A and Class B shares in Roblox. Class B shares carry 20 votes per share (versus 1 vote per Class A share), which is a common dual-class structure used by tech founders to retain voting control even as they sell or gift portions of their economic stake. His exact share count at any given moment is disclosed in SEC filings, specifically in Form 4s (filed when an insider buys or sells shares) and in the company's annual proxy statement. Multiply his total reported shares by RBLX's closing price on a given day and you get the equity component of his net worth.
GuruFocus takes a conservative approach: it calculates an "at least" floor based on Form 4 open-market transactions, assuming no activity after the last disclosed filing date. That means the GuruFocus figure tends to lag slightly and undercount his total position, since it excludes shares he has not sold (which still appear in proxy filings). Forbes and Bloomberg typically pull from the full proxy-disclosed share count and apply the current market price, making their figures more current but also more volatile.
Why the number moves so much
Roblox stock has been one of the more volatile names in consumer tech since its IPO. RBLX traded as high as roughly $134 in late 2021 and fell well below $30 during the 2022 market downturn, a swing that would have moved Baszucki's paper net worth by several billion dollars. When you see different sources quoting different figures, that is usually the explanation: they captured the price at different points in time, not that one source is wrong.
Other wealth drivers beyond Roblox equity
Roblox dominates the picture, but it is not the only building block. Baszucki draws a CEO salary and compensation package from Roblox Corporation. As a publicly traded company, those figures are disclosed annually in the proxy statement filed with the SEC. For tech CEOs at companies of Roblox's scale, total annual compensation (base salary plus stock awards and performance bonuses) frequently runs into the tens of millions of dollars per year, though the cash portion is typically a small fraction of the total.
Before Roblox's public listing, Baszucki also benefited from venture capital funding rounds that raised the company's private valuation over time. Early investors and founders often sell a portion of secondary shares during funding rounds or tender offers, which can generate meaningful liquidity even before an IPO. Whether and how much Baszucki monetized during those pre-IPO rounds is not fully public, but it is standard practice for founders to take some cash off the table at that stage.
Beyond Roblox, Baszucki has been publicly associated with philanthropic giving through the Baszucki Group and the Baszucki Brain Research Fund, which focuses on mental health research. Significant philanthropic commitments can reduce the net worth figure that trackers report, since donated assets are typically excluded. His wife, Jan Ellison Baszucki, is a novelist and collaborator on the family's philanthropic work. The family's real estate holdings and any diversified investment portfolio are not publicly detailed, so those components represent an unknown but plausible addition to the headline estimate.
Understanding where the wealth came from requires a quick look at the timeline. Baszucki co-founded Roblox in 2004 alongside Erik Cassel, building it from an educational physics simulator called "Interactive Physics" into the user-generated gaming platform it is today. The company was originally called Dynablocks before being rebranded as Roblox in 2004.
Before Roblox, Baszucki had already built and sold a company. He co-founded Knowledge Revolution in the late 1980s, which made Interactive Physics software for students and teachers. The company was sold to MSC Software in 1998, giving Baszucki his first meaningful exit and the capital and credibility to pursue his next project. That earlier venture is important context: by the time he launched Roblox, he was not a first-time founder, and he understood both the product and business sides of running a software company.
Roblox launched publicly in 2006 and grew steadily, but its trajectory accelerated dramatically during the COVID-19 pandemic in 2020 and 2021 as millions of younger users turned to the platform for social and creative play. Daily active users surged into the tens of millions, the company's private valuation rose sharply, and a direct listing in March 2021 placed the company's market capitalization at roughly $38 billion on its first day of trading. That single event is the primary reason Baszucki entered the billionaire ranks.
He has remained CEO through the full arc, which is relatively rare for a founder who has led a company from a small startup to a multi-billion-dollar public company. His continued operational role means his compensation and unvested equity grants continue to accumulate, adding to the wealth estimate over time.
How to verify the number yourself
If you want to check the current estimate rather than rely on a cached figure, here are the most reliable sources and what to look for in each one.
- Forbes Real-Time Billionaires: Search "David Baszucki" on Forbes.com and look for the real-time net worth tracker. It shows the current estimate, the date of the last update, and a brief breakdown of how the figure is calculated. This is the most commonly cited source and updates frequently.
- Bloomberg Billionaires Index: Go to Bloomberg's Billionaires tracker and search his name. Bloomberg's methodology page on each profile explains exactly how it builds the estimate, including which share classes it counts and how it handles unvested equity. This is particularly useful for understanding why the number may differ from Forbes.
- SEC EDGAR filings: Go to sec.gov and search for Roblox Corporation or David Baszucki directly. You are looking for two document types: Form 4 filings (filed within two business days of any insider transaction) and the annual DEF 14A proxy statement (filed each spring), which lists his exact share count as of the record date.
- Roblox Investor Relations page: Roblox's own IR site links directly to SEC filings, earnings releases, and annual reports. The proxy statement is the most useful document for share ownership data.
- GuruFocus insider tracker: Useful as a secondary check, especially to see a history of Form 4 transactions over time. Keep in mind it calculates a floor estimate, not a comprehensive total.
- RBLX stock price: Any major financial data provider (Yahoo Finance, Google Finance, Bloomberg) will show the current RBLX price. Cross-reference this with his disclosed share count from the proxy to do your own back-of-envelope calculation.
The most defensible DIY estimate is: (total shares from latest proxy) multiplied by (current RBLX price) plus a conservative allowance for cash compensation accumulated over prior years. You will arrive at a number consistent with what Forbes and Bloomberg publish.
Net worth vs. actual cash: what the number really means
This is the part most readers overlook. A $5 or $6 billion net worth figure does not mean David Baszucki has $5 or $6 billion sitting in a bank account. The overwhelming majority of that figure represents Roblox shares, which are an asset, not cash. To convert that equity into spendable money, he would need to sell shares, which triggers taxes, requires SEC compliance (founders must follow Rule 10b5-1 trading plans and file with the SEC before selling), and can move the stock price if done in large volumes.
In practical terms, the day-to-day liquidity available to someone like Baszucki is his salary and any pre-planned share sales under a 10b5-1 plan, both of which are substantial but far smaller than the headline net worth figure. The $5.6 billion estimate is a measure of accumulated wealth and economic ownership, not a measure of cash flow or spending power in any given month.
There are a few other common misconceptions worth flagging. First, estimates from different sources will always vary slightly because they use different methodologies, different share counts, and different update frequencies. A $200 to $300 million difference between Forbes and Bloomberg is not unusual and does not mean one source is inaccurate. Second, the figure can drop significantly without any change in Baszucki's behavior: a 10% decline in RBLX stock alone would reduce his estimated net worth by hundreds of millions of dollars on paper. Third, philanthropic donations reduce the tracked net worth, so a lower figure from one period to the next does not necessarily mean financial losses.
If you are researching Baszucki's wealth for context, the most honest framing is: he is a multi-billionaire whose wealth is tightly coupled to Roblox's market performance, with a best estimate in the $5 to $6 billion range as of early 2026, and the most accurate current figure is always one click away on Forbes or Bloomberg's live trackers.
