Latest estimated net worth: not publicly verified. Public transaction records show that Simon Yiming Ma received equity consideration worth roughly $262 million in Kingsoft Cloud stock in 2021, based on deal values disclosed in SEC filings, but that figure is not the same as his current personal net worth.
Simon Yiming Ma net worth cannot be stated accurately as a single verified figure in 2026. No audited personal balance sheet or reliable wealth ranking establishes his current fortune, while widely circulated online figures are often presented without evidence.
What can be documented is substantial. Ma co-founded Camelot Information Systems, took the company public in New York, later led its privatization, and ultimately participated in a 2021 transaction in which Kingsoft Cloud acquired control of Camelot. SEC records show that Ma received more than 101 million Kingsoft Cloud ordinary shares following that acquisition.
What Is Simon Yiming Ma Net Worth in 2026?
There is no verified 2026 net worth figure for Simon Yiming Ma. Claims placing his fortune at $3 million, $500 million, or even billionaire level should not be treated as established facts unless they are supported by reliable records showing his present assets, investments, debts and ownership positions.
The strongest public evidence points instead to a more useful conclusion. Ma participated in transactions involving hundreds of millions of dollars, and his documented Kingsoft Cloud equity received through the Camelot acquisition alone had an accounting value of roughly RMB1.86 billion, approximately $262 million using the conversion disclosed in Kingsoft Cloud’s acquisition accounts.
That does not mean his current net worth is $262 million. He may have sold shares, retained shares, paid taxes, received additional cash consideration, invested elsewhere or incurred liabilities that are not publicly disclosed.
| Financial measure | What public records show |
|---|---|
| Verified 2026 personal net worth | Not publicly disclosed |
| Common online estimates | Unverified |
| Kingsoft Cloud ordinary shares attributed to Ma after 2021 acquisition | 101,453,974 shares |
| Approximate deal-accounting value of those shares | About RMB1.86 billion, roughly $262 million |
| Other personal assets and liabilities | Not sufficiently disclosed |
| Current Camelot controlling ownership | Kingsoft Cloud, not Simon Ma |
The approximately $262 million figure is calculated from two SEC disclosures. Kingsoft Cloud recorded RMB4.538579 billion, or about $638.023 million, of equity consideration represented by 247,475,446 ordinary shares. A later prospectus identified 101,453,974 Kingsoft Cloud ordinary shares as beneficially owned by Ma following the transaction.
Who Is Simon Yiming Ma?
Simon Yiming Ma, commonly identified in corporate records as Yiming Ma or Simon Ma, is a technology entrepreneur best known for co-founding Camelot Information Systems.
An SEC prospectus states that Ma worked for IBM in the United States from 1986 to 1994 as a software designer developing solutions for IBM customers. It also records two master’s degrees from the University of California, Santa Barbara, one in mathematics and another in computer science, as well as a bachelor’s degree from East China Normal University.
The same filing identifies Ma as Camelot’s chairman and chief executive officer from the company’s founding and confirms that Heidi Chou, another Camelot co-founder and senior executive, is his wife.
Public materials sometimes give conflicting dates for Camelot’s beginning. The business traces its operating history to the 1990s, while SEC records state that the British Virgin Islands holding company called Camelot Information Systems Inc. was incorporated in November 2000.
How Simon Yiming Ma Built His Wealth
Ma’s documented wealth story is closely tied to enterprise technology rather than celebrity endorsements or a public investment portfolio.
Camelot developed enterprise application and financial-industry IT services for companies operating in China. Its customers were served either directly or through large international technology providers, and historical filings identified relationships involving companies such as IBM, Accenture and HP.
The company eventually became large enough to enter the U.S. public markets.
Camelot’s 2010 New York Stock Exchange IPO
Camelot’s American depositary shares began trading on the New York Stock Exchange under the symbol CIS in July 2010.
The IPO priced 13,333,334 ADSs at $11 each, producing an offering size of approximately $146.7 million before any additional over-allotment shares. Camelot described it at the time as the largest U.S. IPO by a Chinese IT services company up to that point.
SEC filings around the offering reported that Ma beneficially owned approximately 23.5 million ordinary shares, or about 12.5 percent of Camelot following the offering in one later prospectus. Because four ordinary shares represented one ADS, his position corresponded to approximately 5.875 million ADS equivalents. At the $11 IPO price, that produced a simple market-value marker of roughly $64.6 million.
That was the value of the disclosed Camelot equity at a particular market price, not Ma’s total net worth.
Why Camelot’s 2014 Privatization Matters
Camelot’s public-market valuation later dropped sharply.
By 2013, Ma, Chou and other executives proposed taking Camelot private. The final agreement offered shareholders $2.05 for each ADS, equivalent to $0.5125 for each ordinary share. Financial adviser materials included in SEC filings placed the company’s implied common-equity value at approximately $98.2 million.
Immediately before the transaction, the 2014 proxy reported that Ma beneficially owned 15,537,232 ordinary shares, or approximately 8.4 percent of Camelot. Chou beneficially owned approximately 14,898,176 shares, or 8.0 percent.
At the $0.5125 transaction price, Ma’s disclosed shares represented roughly $8 million of transaction-value equity. Those shares were rolled into the new ownership structure rather than simply being treated as a public-market holding. The filing shows that Benefit Overseas Limited, controlled by Ma, rolled 15,537,232 shares into the parent structure.
The merger was completed on March 28, 2014, after which Camelot became a wholly owned subsidiary of the acquisition parent and ceased operating as a publicly traded company.
The 2021 Kingsoft Cloud Deal Changed the Wealth Picture
The most important public financial event for evaluating Ma’s later wealth occurred in 2021.
On July 31, 2021, Kingsoft Cloud entered into an agreement to acquire controlling interests in Camelot. The agreement specifically identified Yiming Ma and Heidi Chou as Camelot’s founders, with Ma also serving as seller representative. Benefit Overseas Limited was identified as wholly owned and controlled by Ma.
The transaction documentation initially referenced RMB6 billion as the preliminary merger consideration, subject to adjustment.
Kingsoft Cloud subsequently reported that the completed acquisition had total purchase consideration of approximately RMB5.291 billion, or $743.7 million. This consisted of about RMB752 million in cash and RMB4.539 billion in equity consideration.
That transaction is considerably more useful for understanding Ma’s financial position than unsupported celebrity-net-worth estimates.
How Much Kingsoft Cloud Stock Did Simon Ma Receive?
A Kingsoft Cloud prospectus filed after the acquisition reported that Ma beneficially owned 101,453,974 Kingsoft Cloud ordinary shares, approximately 2.8 percent of the company at that time.
The prospectus registered 60,872,385 of those shares for potential resale and showed 40,581,589 remaining if all registered shares were resold. Registration for resale does not prove that those shares were actually sold.
Kingsoft Cloud’s acquisition accounts valued 247,475,446 shares issued to Camelot shareholders at RMB4.538579 billion. Applying that reported transaction valuation proportionally places Ma’s 101,453,974-share position at roughly RMB1.86 billion, equivalent to approximately $262 million using the dollar conversion in the same filing.
This is one of the most important distinctions in any serious Simon Yiming Ma net worth analysis. $262 million is a historical deal-value estimate for disclosed stock consideration, not proof of a $262 million current net worth.

Documented Financial Timeline
A conventional year-by-year net worth chart would create false precision because Ma’s private assets and liabilities are not available. The more accurate approach is to track documented equity and transaction values.
| Year | Publicly documented financial marker | What it means |
|---|---|---|
| 2010 | Ma held about 23.5 million Camelot ordinary shares | At the $11 IPO ADS price, equivalent equity was roughly $64.6 million |
| 2011 | Ma reported 15.54 million beneficially owned shares | SEC ownership filing showed an 8.9% stake at year-end 2011 |
| 2013 | Buyer group proposed taking Camelot private | Ma and other insiders moved toward private ownership |
| 2014 | Camelot equity valued around $98.2 million in the transaction | Ma rolled approximately 15.54 million shares into the new structure |
| 2021 | Kingsoft Cloud acquisition agreed and completed | Camelot became part of a transaction worth hundreds of millions of dollars |
| 2021 | Ma held 101.45 million Kingsoft Cloud ordinary shares | Deal-accounting value works out to roughly $262 million for this disclosed position |
| 2022 | Kingsoft Cloud acquired additional Camelot interests | Integration continued |
| 2025 | Kingsoft Cloud reported 100% indirect ownership of Camelot Technology | Ma was no longer Camelot’s controlling owner |
The 2011 ownership figure comes directly from Ma’s SEC Schedule 13G, which reported 15,537,232 ordinary shares and 8.9 percent beneficial ownership as of December 31, 2011.
Does Simon Yiming Ma Still Own Camelot?
Not as its controlling shareholder.
This is where many current online biographies become outdated. Kingsoft Cloud first acquired control of Camelot in September 2021 and later purchased additional minority interests. Its filings show further acquisitions in 2022.
Kingsoft Cloud’s 2025 financial disclosures list Camelot Technology Co., Ltd. as 100 percent indirectly owned by the group.
Therefore, descriptions of Ma in 2026 as the current majority owner of an independent, privately held Camelot are not consistent with the latest corporate filings.
He may still have economic exposure through Kingsoft Cloud securities or other investments, but his present holdings are not sufficiently disclosed to reconstruct his personal fortune.
Is Simon Yiming Ma a Billionaire?
There is no reliable public evidence establishing Simon Yiming Ma as a billionaire.
His documented transactions demonstrate substantial wealth, including a nine-figure stock position arising from the Kingsoft Cloud deal. However, demonstrating that someone once received hundreds of millions of dollars of transaction consideration is not the same as proving current assets exceeding $1 billion after taxes, sales, liabilities and changes in investment values.
Calling him a billionaire without additional evidence would therefore go beyond what the public record supports.
Is the $500 Million Simon Yiming Ma Net Worth Estimate Reliable?
A $500 million estimate is possible but not verified.
To establish such a figure responsibly, researchers would need to know how much of Ma’s Kingsoft Cloud consideration he retained, what price he obtained for any shares sold, how much cash he received in the Camelot acquisition, his tax obligations, real estate and private investments, debts and other family ownership arrangements.
Those details are not publicly complete.
The 2021 filings provide evidence that Ma had exposure to assets worth hundreds of millions of dollars, but they do not support presenting $500 million as an audited or confirmed 2026 figure.
What Happened to Simon Ma After the Kingsoft Cloud Acquisition?
The acquisition changed Camelot from a founder-controlled business into part of Kingsoft Cloud’s enterprise-services operation.
Kingsoft Cloud said in 2021 that Camelot’s co-founders and other senior executives would join the company following the transaction.
In February 2022, however, Kingsoft Cloud announced that Shouhu Wang, who had joined Camelot in 2016, remained responsible for Camelot’s overall operation and management while also becoming president of Kingsoft Cloud.
Ma is still historically identified by financial databases as Camelot’s co-founder, chairman and CEO, but the latest corporate structure means those older descriptions should not be interpreted as proof that he continues to control the company independently.
Simon Yiming Ma’s Education and IBM Career
Ma’s early career is unusually well documented compared with his personal finances.
According to Camelot’s SEC filings, he worked at IBM in the United States between 1986 and 1994 and developed software solutions for IBM customers. He later became the central strategic figure behind Camelot’s development.
He earned master’s degrees in mathematics and computer science from the University of California, Santa Barbara, after completing undergraduate studies at East China Normal University.
Some newer biography websites claim that he holds a PhD. Camelot’s SEC filings, however, list two master’s degrees rather than a completed doctorate, so a PhD should not be presented as verified without stronger evidence.
Simon Yiming Ma’s Wife and Family
Ma’s wife, Heidi Chou, played an important role in Camelot rather than simply being associated with the business through marriage.
SEC filings identify Chou as a Camelot co-founder, director and senior executive. They also state explicitly that Ma and Chou are husband and wife. Chou previously worked at IBM and holds an MBA from Stanford University, according to Camelot’s prospectus.
Their publicly known daughter is Rebecca Ma, better known online as Becca Bloom. Reporting by The Wall Street Journal and Tatler Asia identifies Rebecca as the daughter of Simon Ma and Heidi Chou and notes that she grew up in Atherton, California.
Her highly visible luxury lifestyle has helped generate renewed public interest in her parents’ wealth, but her social-media content cannot by itself establish Simon Ma’s personal net worth.
How Reliable Are Online Net Worth Claims About Simon Ma?
The safest way to evaluate them is to separate company value, transaction proceeds and personal net worth.
Camelot’s $98.2 million going-private equity valuation in 2013 did not mean Ma personally owned $98.2 million. Likewise, Kingsoft Cloud’s roughly $744 million purchase consideration in 2021 was for the acquisition transaction, not a payment entirely to Ma.
Even the approximately $262 million attributable to Ma’s disclosed Kingsoft Cloud share position represents the transaction value of securities, not cash in a bank account.
A reliable personal net worth calculation would require subtracting liabilities and taxes while adding all remaining investments, cash, property and other assets. Those records are not publicly available.
