When you search for the net worth of a guy named James Green, you're basically opening a digital Russian nesting doll. Which one are we talking about? Honestly, there are at least three high-profile men with that name whose bank accounts are a frequent topic of internet debate. We’ve got the heavy-hitting tech executive, the elite wrestler who carved a path through the international freestyle scene, and the NASA luminary who literally helped us understand Mars.
Most of the time, when people are clicking around for the James Green net worth, they’re actually looking for the businessman James W. Green, the CEO of Harvard Bioscience. As of January 15, 2026, he’s the one moving the needle in the financial world.

The Business Powerhouse: James W. Green
Let’s talk numbers. Real numbers.
James W. Green has spent years at the helm of specialized tech and medical companies. He isn't just a guy with a salary; he’s an insider with serious skin in the game. Most of his wealth isn't sitting in a checking account—it’s tied up in equity, specifically with Harvard Bioscience Inc (HBIO) and OSI Systems Inc.
Current estimates put the James Green net worth at approximately $21.7 million.
How do we know? Securities and Exchange Commission (SEC) filings. Publicly traded companies have to disclose what their executives own. James W. Green owns roughly 3,111,091 shares of Harvard Bioscience. At today's market rates, that's a massive chunk of change.
But it’s not just HBIO. He’s been a director and officer at Analogic Corp and OSI Systems. If you look at his Form 4 filings, you’ll see a man who knows how to play the long game. He buys. He sells occasionally for taxes. He waits.
Why his wealth fluctuates
Stock prices aren't static. One day Harvard Bioscience is up 10%, the next it's down. This means his net worth can swing by hundreds of thousands of dollars in a single afternoon. It’s the nature of the beast.

- Primary Asset: Harvard Bioscience (HBIO) shares.
- Secondary Assets: Past holdings in Analogic and OSI Systems.
- Estimated 2026 Compensation: Total packages often exceed $2.3 million annually when you factor in stock awards.
The Athlete: James Green (The Wrestler)
Then there's the other James Green. The one who spent his life on a mat, not in a boardroom. This James Green is a legendary freestyle wrestler, a two-time World medalist, and a staple of Team USA.
Wrestling isn't like the NBA. You don't sign a $100 million contract. Wealth here is built through:
- Sponsorships: Brands like Titan Mercury Wrestling Club and major apparel lines.
- Medal Bonuses: The Living the Dream Fund pays out significant cash for World and Olympic medals.
- Coaching: Transitioning from the mat to the sidelines at top-tier programs like Nebraska.
While his net worth isn't public in the same way a CEO's is, experts estimate it to be in the $1 million to $3 million range. It's a different kind of wealth—built on sweat and grit rather than stock options.
The Space Pioneer: Dr. James Green
We can't ignore Dr. James Green, the former Chief Scientist at NASA. He spent 40 years exploring the solar system. While government salaries are public (usually capping out around $200,000 to $250,000 for top-tier roles), his real "net worth" comes from a career of unmatched intellectual legacy.
Since retiring from NASA, he's transitioned into consulting, speaking, and media. High-level consultants with his pedigree can command five-figure fees for a single keynote. It’s safe to say his financial standing is comfortable, likely in the low millions, but his "worth" to humanity is basically immeasurable.
The "Middle Man" Trap
What most people get wrong about James Green’s wealth is the confusion between these individuals. You'll see "net worth" websites mash their biographies together. They'll say James Green the wrestler owns $20 million in Broadcom stock.
He doesn't.
That’s actually a different person entirely, James H. Greene Jr., a director at Broadcom. People see the name and stop reading. Don't be that person. The "Broadcom James" is a billionaire, with holdings valued at over $324 billion.
Mixing up a freestyle wrestler with a Broadcom director is like mixing up a local barista with Howard Schultz.
Actionable Insights for Researching Net Worth
If you're trying to track the wealth of a public figure, stop looking at those generic "celebrity net worth" sites that use the same template for everyone. They are often guessing.

- Check SEC Form 4 Filings: If they are a corporate executive, this is the only way to get the truth. It shows every share they buy or sell.
- Look at Real Estate: Public records for property ownership in high-end zip codes are often more telling than a guessed "salary."
- Analyze Career Longevity: A CEO like James W. Green has been in high-paying roles for 20+ years. Compounded growth is a powerful thing.
- Differentiate the Name: Always verify the middle initial. The "W" in James W. Green is the difference between a $21 million net worth and a $22,000 net worth for a different James Green in the same database.
To get a clear picture of the James Green net worth situation, you have to look at the specific career path. For the business mogul, it's a story of corporate equity. For the athlete, it's a story of brand and coaching. For the scientist, it's a story of a long-term government career followed by private sector demand.
