David Baszucki's Net Worth in 2025: The Numbers
Baszucki's fortune in 2025 stands at $7.6 billion, a figure that places him firmly among tech's wealthiest founders. This represents the financial culmination of a platform that has captured millions of young creators worldwide.
Estimated net worth in dollars
Pinning down Baszucki's exact wealth proves challenging, with estimates varying dramatically across sources. Celebrity Net Worth takes a conservative approach, placing his fortune at approximately $2.4 billion. Other financial trackers push higher, reflecting the volatile nature of tech valuations tied to public market performance.
What's undeniable is the scale of wealth generated primarily through his Roblox Corporation stake. His net worth has experienced significant swings alongside the company's stock price, which has seen both meteoric rises and sharp corrections since going public.
His 2021 compensation package tells its own story—$233 million consisting largely of stock options that vest over time. This structure creates direct alignment between his personal wealth and company performance, a common approach for founder-CEOs.
How much of Roblox does he own?
Baszucki holds approximately 13% of Roblox Corporation, translating to roughly $4.2 billion in value at current market prices. This equity position forms the bedrock of his wealth, reflecting both his founder status and continued leadership role.
His influence extends beyond pure ownership through his dual role as Chairman of the Board and Chief Executive Officer. This positioning grants him substantial control over strategic direction, amplifying his impact beyond what ownership percentages alone might suggest.

This growth corresponds directly with Roblox's evolution from niche gaming platform to metaverse contender. The March 2021 direct listing marked the inflection point, instantly creating billionaire status on paper. Before going public, his wealth was substantial but largely illiquid.
What's David Baszucki's net worth according to Forbes?
Forbes maintains a more conservative tracking approach, focusing on verifiable assets rather than peak valuations. Their real-time billionaires list typically reflects his Roblox holdings as the primary wealth driver.
His 2023 Forbes ranking placed him around position #500 globally. That number fluctuates considerably with stock performance—during Roblox surges, he can climb hundreds of positions overnight.
Forbes also tracks his systematic share liquidation since going public. Through SEC filing analysis, they've documented approximately $1.1 billion in Roblox stock sales since 2021, enabling wealth diversification beyond his founding company.
What makes Baszucki's wealth particularly noteworthy is its singular origin—built from one company he created rather than inherited wealth or multiple ventures. His path from educational software developer to gaming mogul demonstrates how a well-executed idea can generate extraordinary wealth in today's digital economy.
How Roblox Became a Billion-Dollar Platform
The engine behind Baszucki's fortune isn't just another gaming company—it's a self-reinforcing ecosystem that turns players into creators and creators into revenue generators. Roblox's evolution from educational tool to gaming giant with 77.8 million daily active users in Q1 2025 reveals how strategic platform design can create extraordinary value.
The rise of user-generated content
Roblox cracked the code on sustainable growth through its user-generated content approach. The platform operates on a simple but powerful premise: give people tools to build, and they'll create experiences that attract others who also want to build. With 12.3 million monthly active developers, this creates a continuous cycle of content creation and consumption.
The numbers demonstrate the model's effectiveness. Developers published over 44 million games in Q2 2025 alone, with 70% incorporating AI-generated assets. This isn't just quantity—it's quality that competes with traditional gaming.
"Adopt Me," one of the platform's breakout successes, has been played over 20 billion times and maintains 500,000 concurrent players, outperforming established titles like Dota 2 and GTA V.
AI-powered tools like Cube 3D have accelerated this growth by reducing development time by 35%. Solo developers and small teams can now compete with larger studios, democratizing game creation and expanding the talent pool contributing to the platform's success.
Roblox's IPO and market valuation
March 10, 2021 marked the moment Baszucki's vision became liquid wealth. Roblox's direct listing on the New York Stock Exchange under ticker "RBLX" bypassed traditional IPO constraints, allowing employees and early investors to sell shares directly to public markets.
The market's response was immediate and decisive. Despite a reference price of $45 per share, the first trade executed at approximately $64.50, instantly valuing the company at $41.9 billion. This valuation reflected confidence in a platform that had already captured 32.6 million daily active users.
The trajectory tells the story of accelerating growth:
- 2017: $1.1 billion
- 2018: $2.5 billion
- 2020: $4.0 billion
- 2021: $38.0 billion
Current performance validates that early market confidence. Q2 2025 results showed $1.1 billion in quarterly revenue and $1.4 billion in bookings, representing year-over-year growth of 21% and 51% respectively.
Revenue streams: Robux, ads, and partnerships
Roblox's financial engine runs on multiple cylinders, with virtual currency Robux as the primary driver. Users purchase Robux to enhance their gaming experiences, generating $2.9 billion in transactions during 2022, with average annual spending of $59.85 per player.
The platform's economic model rewards creators directly. Developer Earnings hit $316.4 million in Q2 2025, up 52% year-over-year. The top 1,000 developers now average $820,000 annually—a 570% increase since 2019—while the top 10 developers average $33.9 million.
Beyond virtual currency, Roblox has expanded into advertising through "Rewarded Video ads," where users watch advertisements for in-game benefits. The format has proven popular, with 87% of surveyed users expressing favorable opinions. Strategic partnerships with brands like Marvel, LEGO, Disney, and Nike have created additional revenue streams while enhancing user experiences.
The company projects continued growth with full-year 2025 revenue growth of 22-25% and bookings growth of 34-37%. These projections position Roblox ahead of many traditional gaming competitors while solidifying its role as the foundation of Baszucki's billion-dollar fortune.
Insider Trading and Stock Holdings
Baszucki's approach to wealth management reveals a methodical strategy built around systematic diversification. His stock transaction history tells the story of a founder carefully balancing personal financial security with ongoing company leadership. Over five years, he's executed 47 transactions in Roblox Corp (RBLX)—every single one a sale, with zero purchases.
Breakdown of recent stock sales
The scale of Baszucki's share liquidation reflects serious wealth planning. June 2025 alone generated over $83.5 million in proceeds. His most significant single transaction moved 780,910 shares on May 5, 2025.
The 2025 selling activity breaks down across multiple entities:
- Direct sales and 10b5-1 plans: approximately 4.7 million shares worth over $400 million
- The Baszucki Family Foundation: about 920,000 shares worth approximately $87 million
- 2020 Jan Baszucki Gift Trust: roughly 725,000 shares worth about $69 million
A June 26, 2025 SEC filing documented another 167,408 shares sold, netting approximately $18 million. Since the 2021 public listing, his total share sales have reached an estimated 17.1 million shares, generating approximately $1.1 billion in proceeds.
SEC Form 4 filings and what they reveal
Securities and Exchange Commission filings provide transparency into Baszucki's systematic approach. A recent Form 144 filing outlined a proposed sale of 47,928 shares valued at $5,021,895.84 through Morgan Stanley Smith Barney LLC.
The filings consistently show reliance on Rule 10b5-1 plans—preset trading schedules that eliminate accusations of insider trading. His June 30, 2025 Form 4 explicitly states: "The transactions reported in this Form 4 were effected pursuant to a Rule 10b5-1 Plan adopted by the Reporting Person on November 04, 2024".
Current share ownership and value
Despite extensive selling, Baszucki maintains substantial skin in the game. As of November 13, 2024, he owned 58,004,180 shares of Roblox Corporation, representing 8.8% company ownership. This reflects a steady decline from his February 2024 position of 59,932,481 shares (9.5% ownership).
His ownership trajectory shows deliberate portfolio management:
- February 2022: 12.10% ownership
- February 2023: 10.40% ownership
- February 2024: 9.50% ownership
- November 2024: 8.80% ownership
At current valuations, his 58,004,180 shares carry approximately $6.52 billion in value, anchoring his wealth position. Even after significant diversification, he remains Roblox's second-largest shareholder behind The Vanguard Group.
Some reports suggest his direct holdings may be as low as 212,434 shares (worth approximately $26.20 million) as of July 30, 2025, indicating sophisticated wealth structuring through various trusts and entities.
From Physics Simulations to Roblox: Career Timeline
Baszucki's path to billions started decades before Roblox existed. His early work in educational software established patterns that would define his approach to technology: making complex systems accessible, empowering users to create, and building tools that scale beyond their original purpose.
Early ventures: Interactive Physics and Knowledge Revolution
The foundation was laid in the late 1980s when Baszucki co-founded Knowledge Revolution with his brother Greg. Interactive Physics, their flagship product, allowed students to create and measure 2D physics experiments. The software delivered remarkable accuracy—capable of modeling complex physics problems with results comparable to analytic solutions.
Interactive Physics found global success, eventually translated into nine languages and selling millions of copies. The brothers followed up with Working Model in the early 1990s, an enhanced version that incorporated 3D components.
The exit came in December 1998 when MSC Software acquired Knowledge Revolution for $20 million. Baszucki stayed on as vice president and general manager of MSC's desktop simulation division from 2000 to 2002. The experience taught him how to scale educational software and navigate corporate acquisitions—lessons that would prove valuable later.
The founding of Roblox
After MSC, Baszucki launched Baszucki & Associates, an angel investment firm. But the pull of building remained strong. In December 2003, he reunited with Erik Cassel, his former VP of Engineering from Interactive Physics.
Their initial prototype went by "eBlocks," then "DynaBlocks". The rebrand to Roblox—combining "robots" and "blocks"—happened in January 2004. The name change signaled something important: this wasn't just another educational tool. It was a platform for creation itself.
Key milestones in Roblox's growth
Roblox Corporation launched officially in March 2004. After beta testing in 2005, the platform went public on September 1, 2006. The early years required patience—building the infrastructure for user-generated content meant solving technical problems that didn't exist in traditional gaming.
Growth came steadily. The company expanded from 68 employees in December 2013 to 163 by December 2016. March 2017 brought a critical funding milestone: $82 million led by Meritech Capital Partners and Index Ventures. The money validated their vision and fueled expansion.
International markets became the next priority. Roblox International launched in 2018 under Chris Misner's leadership. By 2019, the platform had entered Chinese markets (partnering with Tencent), plus German and French territories.
March 10, 2021 marked the culmination: Roblox Corporation went public on the New York Stock Exchange. The direct listing instantly created billions in paper wealth for Baszucki, validating nearly two decades of work that began with physics simulations and evolved into a platform where millions create their own worlds.
Beyond Business: Philanthropy and Public Image
Baszucki's approach to giving mirrors his business strategy—targeted, data-driven, and designed for maximum impact. Rather than scattering donations across numerous causes, he and his wife Jan have focused their philanthropic efforts on areas where personal experience meets pressing need.
The Baszucki Group and brain research funding
When Roblox went public in March 2021, the windfall created an opportunity for Baszucki and Jan Ellison Baszucki to formalize their giving through the Baszucki Group. Their focus became clear early on: brain research, specifically bipolar disorder research, driven by their family's direct experience with the condition.
The Baszucki Brain Research Fund has committed over $13 million to research grants targeting bipolar disorder. This wasn't just charitable giving—it was strategic investment in scientific progress. In September 2022, Baszucki joined forces with Google co-founder Sergey Brin and Keystone Capital chairman Kent Dauten, together committing $150 million toward bipolar disorder research.
The approach mirrors successful tech funding models. Throughout 2022, the fund partnered with the Milken Institute to distribute grants to 45 scientists worldwide, providing up to $200,000 per award. Rather than betting on a single research approach, they've created a portfolio of scientific bets.
Donations to UCSF and other causes
Personal experience drives their giving decisions. In December 2021, the couple committed $6 million over five years to UC San Francisco, launching the Baszucki Lymphoma Therapeutics Initiative. This donation stems from Jan's father's recovery from near-fatal lymphoma—turning a family crisis into funding for others facing similar battles.
Baszucki has structured his ongoing philanthropy with the same discipline he applies to business decisions. Any additional CEO compensation beyond his base salary flows directly into charitable purposes. It's a systematic approach that ensures giving grows alongside company success.
Public statements on social justice
The Baszucki Group operates across three core areas: making metabolic health mainstream, reshaping farming and food systems, and advancing non-partisan voting reform. These aren't random choices—each reflects areas where the couple sees both urgent need and potential for measurable progress.
Jan Ellison Baszucki has been notably transparent about their family's experience using ketogenic diets to manage their son's bipolar disorder. This openness about personal struggles adds authenticity to their philanthropic mission. When you're funding research into conditions affecting your own family, the motivation becomes clear to everyone involved.
Conclusion
David Baszucki's path from physics teacher to multi-billionaire offers a masterclass in building sustainable wealth through user empowerment. His $7.6 billion net worth in 2025 isn't just about personal fortune—it represents the value created when millions of people are given tools to build their own digital experiences.
The numbers validate the strategy. Roblox's 2021 public debut instantly created a new billionaire, but Baszucki's methodical approach to wealth management—selling $1.1 billion in shares while maintaining his position as the company's second-largest individual shareholder—shows strategic thinking beyond the initial windfall.
What makes this story particularly compelling is how user-generated content became the engine of wealth creation. With 77.8 million daily users and 12.3 million monthly developers, Roblox proved that giving people creation tools generates more value than traditional top-down content production.
The platform's virtual economy, powered by Robux transactions and brand partnerships, has created a self-sustaining flywheel that continues generating returns years after launch.
Yet Baszucki's impact extends beyond balance sheets. The Baszucki Group's $13 million commitment to bipolar disorder research and $6 million toward lymphoma therapeutics demonstrates how platform-generated wealth can fund meaningful medical advances.
Their focus on metabolic health, food systems, and voting reform shows an understanding that true legacy comes from addressing real-world problems.
For entrepreneurs watching from the sidelines, Baszucki's journey reveals that patience and platform thinking can generate extraordinary outcomes. He didn't chase quick exits or pivot to trending technologies—he stayed focused on a core insight about human creativity and scaled it methodically over two decades.
The Roblox story isn't finished. While Baszucki's personal wealth continues growing with the platform's expansion, his real achievement lies in creating a digital space where millions of users discover they can be creators, not just consumers.
That shift in perspective—from passive entertainment to active creation—may prove to be his most valuable contribution to the digital economy.
