Marc G. Swanson is the CEO of United Parks & Resorts (the parent company of SeaWorld Entertainment), and based on publicly available SEC filings, insider trading disclosures, and compensation data, his estimated net worth as of early 2026 sits in the range of $13 million to $19 million. The bulk of that figure comes from his equity holdings in the company he runs, with MarketScreener pegging it at approximately $13 million as of March 30, 2026, and Trendlyne's shareholding tracker showing over $18.7 million based on December 2025 filings.

Which Marc G. Swanson are we talking about?
This is worth sorting out upfront because searches for "Marc G. If you are specifically looking for Marc Kennedy curler net worth, note that this article discusses a different person, Marc G. Swanson. Swanson" can occasionally surface confusion with other public figures who share similar names. The Marc G. Swanson with a documented public financial footprint is the one tied to SeaWorld and its current parent company, United Parks & Resorts. His professional bio is consistent across SEC filings, proxy statements, and the company's investor relations pages: he holds a bachelor's degree in accounting from Purdue University, an MBA from DePaul University, and is a Certified Public Accountant (CPA). He was appointed interim CFO in June 2015, permanent CFO in August 2017, interim CEO in April 2020, and has served as full CEO since May 2021. Every net worth estimate you'll find for "Marc G. Swanson" online is built from those public records, so if you're finding estimates, they almost certainly refer to this person.
If you arrived here looking for a different Marc Swanson, perhaps a private individual or someone in a different field, there is essentially no public financial data to work from, since the research infrastructure that produces net worth estimates relies on SEC filings and public company disclosures. The figures in this article apply specifically to the United Parks & Resorts CEO.
What net worth estimates actually include (and what they leave out)
When a site publishes a net worth figure for a public company executive like Marc G. Swanson, it is working almost entirely from publicly disclosed information. That means the estimate reflects what can be seen, not necessarily the full picture. Here is what typically goes into the calculation:
- Equity holdings: shares of company stock reported in SEC Form 4 filings and proxy statements
- Vested stock awards and stock options: values derived from disclosed compensation tables
- Annual cash compensation: base salary, bonuses, and other cash items from proxy filings
- Any publicly known real estate or asset transactions (rarely available for this executive at this time)
What the estimates do not include, and cannot include without private knowledge: personal savings accounts, private investments outside the company, real estate holdings not in public records, retirement accounts, liabilities and debts, or any business interests that do not require public disclosure. For someone like Swanson, whose wealth is largely tied to his company equity, the visible portion is probably a reasonably representative slice of total wealth, but it is still an incomplete picture.
The current net worth estimate and how it was built
The most defensible estimate for Marc G. Swanson's net worth as of mid-2026 falls between $13 million and $19 million, with the middle of that range, around $14 million to $16 million, being the most reasonable working figure given the data available. If you are searching for Marc Oswald net worth specifically, it is important to verify the person and the underlying public filings first Swanson's net worth. If you are also researching marc kennedy net worth, it helps to compare how different outlets use public filings and private-data assumptions. If you are specifically looking for Marc Ostrofsky net worth, this article focuses on Marc G. Swanson and his public-company disclosures instead. Here is how the major data points stack up:
| Source | Estimate / Figure | Basis |
|---|---|---|
| MarketScreener | $13 million (as of March 30, 2026) | Insider holdings and market value of disclosed shares |
| Trendlyne (Dec 2025 filings) | $18.7 million+ | Shareholdings in United Parks & Resorts ( |
| Simply Wall St | ~$6.53 million (direct ownership only) | 0.38% direct stake in company shares at then-current price |
| CoreStreet (as of Oct 2025) | At least $4 million | Form 4 insider trade based; conservative floor, not a ceiling estimate |
The spread between these figures comes down to methodology, timing, and what each platform counts. CoreStreet's $4 million figure is explicitly a floor derived from tracked insider trades, not a total net worth estimate. Simply Wall St's $6.5 million reflects only direct share ownership, not vested options or other equity. Trendlyne's $18.7 million is the most comprehensive shareholding figure but may combine different share classes or count unvested awards. MarketScreener's $13 million appears to use a similar methodology and is the most recently updated figure, making it a reasonable anchor point.
Where the money comes from: income and wealth sources
Executive compensation
Swanson's compensation as CEO of United Parks & Resorts is disclosed annually in the company's proxy statement filed with the SEC. For 2025, total compensation came in at $4,891,868, a significant jump from 2024's $1,078,031. The 2024 figure broke down as: base salary of $450,000, a bonus of $7,965, stock awards of $337,496, stock option awards of $274,559, and other compensation of $8,011. The 2025 figure was substantially higher due to stock award valuations, which can swing dramatically from year to year depending on grant timing and company share price.
Equity in United Parks & Resorts
The largest chunk of Swanson's disclosed wealth is his equity stake in United Parks & Resorts. As of late 2025 filings, he holds shares worth approximately $13.6 million in the parent company. Executives in his role typically accumulate equity through annual stock awards that vest over multi-year periods. Given that he has been with SeaWorld/United Parks since well before his CEO appointment, he has had multiple years of vesting cycles working in his favor. The value of this holding fluctuates with the company's share price, so any estimate has a built-in moving-target problem.
Accumulated compensation over a long career
Swanson did not arrive at the CEO role from outside the company. He worked through the ranks as CFO and interim CFO before taking the top job, meaning years of salary, bonuses, and equity awards preceded his current role. That career arc, combined with his CPA background suggesting a financially disciplined approach to personal finance, suggests his accumulated savings and investments outside the company are likely meaningful but, by definition, not something we can put a precise number on.
How to verify or update this estimate yourself
If you want to do your own digging or check whether these figures have been updated since this article was written, here are the sources that actually matter:
- SEC EDGAR (edgar.sec.gov): Search for "United Parks & Resorts" DEF 14A filings. The annual proxy statement includes the Summary Compensation Table, which gives you base salary, bonus, stock awards, and total compensation for the CEO. The most recent filing as of this writing is the DEF 14A filed April 30, 2026.
- SEC EDGAR Form 4 filings: Search for Marc G. Swanson as an insider. Form 4 disclosures show every purchase, sale, or award of company stock and are filed within two business days of a transaction. These are the raw data behind the CoreStreet and MarketScreener estimates.
- United Parks & Resorts investor relations (seaworldinvestors.com): The management team page and annual reports are official sources for his role, tenure, and bio details.
- Salary.com executive pay pages: These aggregate and present proxy data in a readable format, useful for quick compensation cross-checks.
- Trendlyne and MarketScreener insider pages: Updated regularly from public filings, these give a running estimate of share value and are as current as the last Form 4 filing.
The honest answer is that no single website has a "correct" net worth figure, because the true number includes private information nobody outside his household knows. But by combining the proxy statement compensation data with the Form 4 equity position, you can build a solid floor estimate that is grounded in real public data rather than guesswork.
Why the numbers vary so much across sites
It is genuinely not unusual to see net worth estimates for the same person ranging by millions of dollars across different sites. For Marc G. Swanson specifically, the $4 million to $18.7 million spread you will encounter comes down to a few predictable reasons:
- Different data snapshots: A figure pulled in October 2025 will differ from one pulled in March 2026 if the stock price moved, options vested, or new awards were granted in between.
- Methodology differences: CoreStreet explicitly tracks only insider trade activity and calls its figure a minimum. Trendlyne aggregates all disclosed shareholdings. These are genuinely different things, not competing answers to the same question.
- Vested vs. total granted equity: Some platforms count only shares already vested and owned; others include unvested awards that the executive will receive in the future if they remain employed. That can add or subtract millions.
- What counts as "net worth" vs. gross asset value: A site that does not subtract estimated liabilities (like margin loans against stock holdings or other debts) will always produce a higher number than one that tries to net things out.
- Update frequency: Some sites refresh data with every new SEC filing; others update quarterly or less often. Swanson's 2025 total compensation of nearly $4.9 million is only visible to sites that picked up the April 2026 proxy filing.
The practical takeaway: treat any single net worth figure for an executive like Swanson as a directional estimate, not a precise measurement. The $13 million to $19 million range is a reasonable working window as of mid-2026, and the best way to check whether it has moved is to look at the current stock price of United Parks & Resorts (ticker: PRKS) and multiply by his disclosed share count from the latest Form 4. That calculation alone gets you most of the way to a current, defensible estimate.
How Swanson's wealth compares to other public figures named Marc
In the context of executives and notable public figures named Marc, Swanson sits comfortably in the mid-tier range. His wealth is tied almost entirely to his corporate equity and compensation rather than entrepreneurial ventures or media careers, which makes him somewhat comparable in profile to other Marcs whose net worth derives from executive roles rather than business ownership. This site covers a range of Marcs across industries, and the pattern of equity-heavy, compensation-driven wealth is common among corporate executives, as opposed to founders or entertainers whose wealth can scale much more dramatically (or collapse more dramatically) based on a single business outcome.
FAQ
How can I verify Marc G. Swanson’s net worth number myself without relying on any single website?
Start with the most recent Form 4 to get his disclosed PRKS share count, then multiply by the current PRKS share price. Next, check the proxy statement for the year’s equity awards and whether they are vested, because only vested shares are typically straightforward to value. Add any cash or other publicly disclosed holdings if available, but expect most sites to miss private assets and liabilities.
Why do different sites give such different net worth figures for Marc G. Swanson?
Most of the spread comes from (1) whether they include only owned shares versus also valuing options and unvested awards, (2) whether they use market price at the time of their scrape versus at filing dates, and (3) whether they treat share classes differently. For executives, the equity accounting choice can shift the estimate by millions even when the underlying filings are the same.
Do unvested stock awards or options count toward Marc G. Swanson’s net worth?
Some calculators value unvested awards as if they were already owned, which can inflate estimates. A more conservative approach is to treat unvested awards as contingent, and only count vested shares or clearly exercisable options. The proxy statement usually helps you distinguish these categories.
What is the fastest way to tell if Marc G. Swanson’s net worth estimate has likely changed since the last update?
Watch two things: the PRKS share price trend and any new Form 4 filings that change his holdings. Even without new awards, a price move alone can materially change the equity value portion of his net worth.
How reliable is a “net worth” estimate compared to using compensation and equity filings directly?
Compensation and Form 4 filings are grounded in public reporting, so they are more reliable than private-asset assumptions. However, even a filing-based approach still misses the value of private investments, real estate not listed in public disclosures, retirement accounts, and personal debt. Treat the result as a floor or best-available estimate, not the complete number.
If Marc G. Swanson sells shares, will that automatically lower his net worth?
Not necessarily. Selling shares can reduce equity holdings, but the proceeds may be reinvested into other assets. Net worth could stay similar or even increase if he reinvests into higher-value assets or if share price rises between the sale and the next valuation snapshot. The key is to track both share count changes and subsequent filings.
How should I handle the common name confusion with other people named Marc Swanson?
Use cross-checks from filings, not memory. Confirm the executive role, employer, and any identifiers in the proxy statement, then match the Form 4 to that same company (United Parks & Resorts, ticker PRKS). If the filings refer to a different company or a different job title, the net worth figure is probably for someone else.
Why did his compensation jump in 2025 compared with 2024, and does that mean his net worth jumped equally?
Higher compensation in a given year often reflects stock award valuation timing, not an immediate increase in liquid wealth. Your best indicator for net worth movement is the change in disclosed equity holdings over time and the current PRKS price, not the headline compensation total alone.
What should I do if I want the “most defensible working figure” for Marc G. Swanson right now?
Use a range, not a single number. Build a conservative floor from vested shares times current price, then create a higher scenario if you choose to value vested options or awarded-but-not-fully-vested equity. The article’s mid-range guidance works best as a starting point, but your custom calculation should reflect the latest share count.
Can retirement accounts or personal trusts materially change Marc G. Swanson’s real net worth?
Yes, potentially. The public data focus on company equity and compensation, while retirement accounts and trusts can hold significant assets that are not disclosed in a way that net worth calculators can reliably capture. That is why any estimate based on public records should be treated as incomplete, even when it is carefully calculated.
