Chad Mirkin Net Worth: Estimates, Sources, and How to Verify

Chad A. Mirkin's net worth is estimated somewhere between $364,000 and $785,000 based on publicly traceable stock holdings from SEC filings, with a best-supported mid-range figure of roughly $500,000 to $600,000 as of mid-2026. These figures reflect only his documented insider shareholdings in publicly traded companies and almost certainly undercount his total wealth, since they exclude private company equity, academic compensation, licensing revenue, and other assets that are not required to be disclosed publicly.

Which Chad Mirkin are we talking about?

This article is about Chad Alexander Mirkin, born November 23, 1963 in Phoenix, Arizona. He earned his B.S. from Dickinson College in 1986, his Ph.D. from Penn State University in 1989, and completed postdoctoral work at MIT before joining Northwestern University. Northwestern’s official faculty profile lists Chad A. Mirkin’s Ph.D. from Penn State University in 1989 and describes his research and academic roles at Northwestern. He is not to be confused with anyone else who shares the name. The Chad Mirkin discussed in financial and scientific contexts carries the middle initial "A." and is consistently identified in SEC filings, academic profiles, and press releases under the full name "Chad A. Mirkin, Ph.D." His identity is well-documented across Northwestern University's official faculty directory, multiple SEC EDGAR filings (including Form 4 and Schedule 13D documents), and peer-reviewed publication records.

He is one of the most cited chemists in the world and holds the Rathmann Professorship of Chemistry at Northwestern. He also serves as Director of the International Institute for Nanotechnology there. His name surfaces in financial databases primarily because of his equity stakes in several companies he co-founded, which generated SEC disclosure obligations. If you are also curious about his kim director net worth, the key is to trace which public-company holdings are documented versus what is likely to be private equity stakes in several companies. Those filings are where the net worth estimates come from.

The net worth estimate: range and best figure

Three financial data aggregators have published estimates of Chad Mirkin's net worth, and they vary significantly depending on what data each site used and when it was calculated. If you are also looking into Mali Kinberg's net worth, the same idea applies: estimates often depend on what financial data is publicly traceable mali kinberg net worth.

The CoreStreet figure is almost certainly a floor rather than a real estimate. It appears to capture only the value of a specific transaction or a residual holding at a point in time when share prices were depressed. The GuruFocus figure is the most robustly sourced of the three, as it explicitly states it derives from SEC Form 4 filings that track all reported insider transactions over time. The Benzinga figure sits in the middle and uses a similar SEC-based methodology but arrives at a different number due to different assumptions about which holdings are still active. Taking these together, the best-supported estimate for Chad Mirkin's publicly traceable net worth is in the range of $364,000 to $785,000, with roughly $500,000 to $600,000 as a reasonable midpoint. Again, this almost certainly represents only a slice of his actual wealth.

How net worth is calculated here

Net worth is total assets minus total liabilities. For a private individual like Chad Mirkin, the challenge is that most of those assets are not publicly reported. If you are comparing sources on Chad Zaemisch net worth, it is especially important to check how each site handles private holdings and SEC disclosure thresholds Chad Mirkin. What we can see are the assets that trigger a legal disclosure requirement, primarily equity stakes in public companies reported through the SEC.

The methodology used to arrive at the estimates above works like this: when an insider (a director, officer, or major shareholder) at a public company buys, sells, or receives shares, they are required to file a Form 4 with the SEC within two business days. Financial data sites like GuruFocus compile these forms, tally the net shares remaining after all reported transactions, and then multiply those shares by the current market price to produce a dollar figure. That is what "at least $785,175" means. It is the calculated value of known stock holdings. It is not a comprehensive wealth figure.

What gets excluded from these estimates is substantial: private company equity (stakes in ventures that have not gone public), real estate, bank accounts, academic salary and accumulated savings, royalty income from patents and licensing, deferred compensation, and any assets held through family trusts or LLCs that are not named in public filings. For someone like Chad Mirkin, who has co-founded multiple companies over several decades and holds patents across nanotechnology, the excluded categories likely dwarf the visible ones.

Where his income and wealth come from

Chad Mirkin's wealth has several distinct layers, and understanding them matters if you want to judge how credible any single number is.

Academic salary and compensation

As a named professor at Northwestern University (Rathmann Professor of Chemistry) and director of a major research institute, Mirkin commands a competitive academic salary. Endowed professorships at top-tier research universities typically come with salaries in the $300,000 to $500,000 range for senior faculty of his standing, though Northwestern does not publicly disclose individual compensation. This steady income stream is separate from and in addition to any equity holdings.

Founder equity in spun-out companies

This is the most significant potential source of accumulated wealth. Mirkin has co-founded multiple companies, including Nanosphere (a molecular diagnostics company that eventually went public on NASDAQ), NanoInk (nanopatterning tools), Aurasense (which later became Exicure), PacDNA, Azul 3D (a high-speed additive manufacturing company), and Mattiq (which launched with $15 million in seed funding). Each of these represents a potential equity position that may have produced returns at various stages of the company's development.

For Nanosphere specifically, SEC prospectus documents show that Mirkin received 299,400 shares when Nanosphere LLC converted into Nanosphere, Inc. The company later went public, creating a real liquidity event. For Exicure, SEC Schedule 13D filings confirm he was a 10% owner and director, with shares acquired through a merger exchange involving preferred stock and options. These events produced documented, verifiable wealth, though the exact proceeds depend on when and whether shares were sold.

Patents, licensing, and research commercialization

Mirkin holds hundreds of patents. Technology licensing is a real and often underestimated income source for prolific academic inventors. When university-developed technology is licensed to commercial partners, the inventor typically receives a percentage of licensing revenue under the university's IP sharing policy. Over a career spanning more than three decades of heavily patented nanotechnology research, this income stream could be substantial, but it is almost entirely opaque to outside observers.

Board roles and advisory positions

Mirkin has served on boards including Nanosphere (director from 2000 to May 2013) and NanoInk (director from 2002 to 2010), as well as Exicure and Azul 3D. A GlobeNewswire press release announcing Nanosphere’s annual meeting and board/director changes identifies Chad A. Mirkin, Ph.D. in connection with the company’s board context Nanosphere annual meeting and board changes. Board positions at public companies typically include cash retainers and equity grants. His service on the President's Council of Advisors on Science and Technology (PCAST) is an advisory government role that typically carries nominal or no compensation, but adds to his public profile and professional network.

Why different sites show different numbers

The gap between $10,330 (CoreStreet) and $785,175 (GuruFocus) for the same person is not a mistake. It reflects genuine differences in methodology, timing, and scope. Here is what drives those discrepancies.

• Snapshot timing: Stock prices move daily. A holding worth $785,000 in March 2026 might be worth $364,000 in May 2026 if the underlying stock fell. Benzinga's recalculated estimate from May 2026 likely reflects a lower share price at that point.
• Which companies are included: Some sites only track filings for one or two companies where Mirkin is an insider. Others aggregate across all his known public company affiliations.
• Transaction assumptions: If a site only captures recent sales and not the full transaction history, it may undercount shares still held. CoreStreet's very low figure likely reflects a single transaction's residual value rather than a full tally.
• Private company exclusion: None of these sites have any visibility into Mirkin's stakes in private companies like Azul 3D, Mattiq, or PacDNA. Those could be worth tens of millions or essentially nothing, and there is no public data to settle the question.
• Stale filings: Form 4 obligations end when someone drops below ownership thresholds. If Mirkin sold down or transferred shares without triggering a new Form 4, the databases stop updating and the "current holding" figure becomes an overcount.

How to verify this estimate yourself

If you want to check the numbers independently rather than take any single site's word for it, here is exactly what to look at and where.

1. SEC EDGAR full-text search: Go to efts.sec.gov and search for "Chad Mirkin" or "Chad A. Mirkin." You will find Form 4 filings (insider transactions), Schedule 13D filings (significant ownership disclosures), and proxy statements that name him as a director. Each Form 4 shows shares bought, sold, or granted, and your running tally of those transactions is the same method the financial sites use.
2. GuruFocus insider page: GuruFocus publishes a dedicated page for Chad A. Mirkin that shows each SEC transaction on record and the current estimated holding value. Compare their tally to your own EDGAR review to spot any discrepancies.
3. Nanosphere historical filings: Nanosphere was publicly traded on NASDAQ under the ticker NSPH before being acquired by Luminex. Its historical SEC filings (prospectus, proxies, annual reports) document the company's founding by Mirkin and the equity issued to founders. These are accessible on EDGAR.
4. Azul 3D and Mattiq press releases: For his private company stakes, the best you can do is track funding announcements. Built In Chicago reported Mattiq's $15 million seed round with Mirkin as a co-founder and director. Seed-stage equity stakes are typically meaningful percentages, but their value is speculative until a liquidity event.
5. Northwestern University public records: Some states have salary transparency databases for public university employees. Illinois does publish state employee salary data, but Northwestern is a private university, so individual faculty salaries are not in any public database. You can review Northwestern's Form 990 (filed with the IRS, available on ProPublica's Nonprofit Explorer) for executive compensation, though professors below a certain threshold may not be individually listed.
6. Patent assignment records: The USPTO's patent database lets you search patents assigned to or invented by Chad Mirkin. The volume and range of patents gives context for the licensing revenue potential, even if the actual dollar amounts are not disclosed.

What could change his net worth

Several near-term factors could push Chad Mirkin's trackable or actual net worth significantly higher or lower over the next one to three years. If you are researching chaz mostert net worth, remember that different databases often estimate wealth using different disclosure rules and timelines trackable or actual net worth.

• Azul 3D exit or funding round: Azul 3D, where Mirkin serves as Board Chairman and Co-Founder, is a private high-speed additive manufacturing startup. A Series A or B funding round at a high valuation, or an acquisition by an industrial company, would crystallize real value from his equity stake. Conversely, if the company struggles or shuts down, that stake goes to zero.
• Mattiq growth trajectory: Mattiq launched with $15 million in seed funding. If it achieves product-market fit in its target market and raises additional rounds, Mirkin's co-founder equity would increase in paper value.
• PacDNA and other private ventures: PacDNA's development as a nucleic acid therapeutics platform could produce licensing deals or a buyout that generates liquidity.
• Movement in public company share prices: The existing SEC-tracked holdings in any remaining public company positions will fluctuate directly with stock price. A significant price movement in any company where he holds reportable shares changes the publicly visible estimate accordingly.
• New company formations: Mirkin has co-founded companies at a sustained pace throughout his career. A new spin-out based on his ongoing nanotechnology research at Northwestern could add another equity position to the ledger.
• Patent licensing milestones: Major licensing deals tied to his nanotechnology patents, particularly in diagnostics, gene regulation, or manufacturing, could generate significant one-time income that would not be visible in SEC filings but would affect total wealth.

The bottom line is that the $364,000 to $785,000 range visible in financial databases is almost certainly a small fraction of Chad Mirkin's actual net worth. The disclosed figures capture only the tip of a much larger financial picture that includes decades of founder equity, licensing revenue, and academic compensation. Anyone working with the publicly available estimates should treat them as a documented floor, not a ceiling. For researchers looking at other figures in this space, the same gap between visible and actual wealth applies broadly to academic entrepreneurs who have spun out multiple private companies, a category that includes a number of people covered on this site.
