Several websites now attach a $500 million label to Simon Yiming Ma, but major wealth rankings do not appear to publish a figure for him. There is no public file supporting Simon Yiming Ma’s net worth claim. The documented facts are narrower.
Ma oversaw the 2013–2014 takeover of Camelot Information Systems, an IT services company whose ownership was valued at roughly $98.2 million. This article separates confirmed numbers from estimates, explains why a reliable figure is hard to find, and covers his career, family, and common name mix-ups.

Who Is Simon Yiming Ma?
Ma is a Chinese-American technology executive. According to his Asia Society board profile, he co-founded Camelot Information Systems in November 2000 and has been the company’s chairman and CEO ever since. Prior to that, he worked as a principal architect at IBM in Silicon Valley for eight years, providing clients with software solutions.
Biographical details vary by source. Legit.ng reports he was born in Beijing on 15 June 1962 and holds a mathematics PhD and two master’s degrees from UC Santa Barbara, plus a bachelor’s from East China Normal University. Another profile gives a 1972 birth year and places Camelot’s start in the mid-1990s. Treat those specifics as unconfirmed.
Simon Yiming Ma Net Worth: What Can Be Verified
A December 2025 review by Mabumbe found no estimate from Fortune, Bloomberg’s billionaire rankings, or audited filings, and called any single figure speculative. That is the honest starting point.
What can be verified is the price of his company. In September 2013, Camelot agreed to a going-private merger at $2.05 per ADS, or $0.5125 per ordinary share. According to the corporations, this suggested a fully diluted stock value of roughly $98.2 million.
That figure values the entire company, not Ma’s personal stake, and it dates to 2013. It is the firmest number in the public record. It still measures one business at one moment, not what its owner holds today after debt, taxes, and other assets.
Where the $500 Million Estimate Comes From
The figure appears on lifestyle and biography sites. Montgomery Klash Magazine describes a half-billion-dollar empire built largely out of public view. KnowledgeNuts puts the 2026 estimate at $500 million while noting that nothing public confirms it.
Neither site shows its math. Montgomery Klash points to real estate in Atherton and private investments across the United States and China, but it names no properties, funds, or filings. The number cannot be verified without them. Read it as a rough online estimate.
A simple comparison shows why caution is warranted. The total value of Camelot was close to $98 million, and China Development Industrial Bank provided $70 million of the buyout funding. A $500 million fortune would require large wealth outside Camelot that no public source documents. That is our reasoning, not a finding.
How the Camelot Buyout Worked
Ma, executive Yuhui Wang, and business president Heidi Chou submitted a non-binding proposal to Camelot’s board on March 12, 2013. Their opening offer was $1.85 per ADS, a 23 percent premium to the prior close, valuing the company at about $82.1 million, according to the Associated Press.
The final deal increased the price by 36.7 percent to $2.05 per ADS. The buyer was a British Virgin Islands business that Ma owned in its entirety.
Shareholders approved the merger in March 2014. Roughly 61 percent of outstanding shares voted, and about 84 percent of those votes backed the deal. Camelot then became a private company. Private firms make no regular public disclosures, which likely explains why so little financial detail exists today.
Real Estate and Other Assets
Legit.ng reports that Ma is based in Atherton, California, one of the most expensive residential markets in the country. None of the outlets we reviewed cited property records or sale prices, so the value of any real estate remains unknown.
Claims of diversified private investments in the U.S. and China appear in a single magazine profile with no named holdings. Ma keeps a low public profile, and we found no interview or public statement from him about his assets. Until documents surface, this part of the picture is blank.
Family and the Becca Bloom Connection
Rebecca Ma, the daughter of Ma and Heidi Chou, goes by Becca Bloom on the internet. Chou was also part of the 2013 buyer group. KnowledgeNuts says the family’s wealth became visible to the public through Becca Bloom’s TikTok videos in 2025.
A daughter’s posts are not evidence of a parent’s balance sheet. Lifestyle content shows spending, not assets. It cannot tell you whether money was earned, borrowed, or shared. It has still fueled much of the curiosity about the family’s finances.
Not Jack Ma or Zhang Yiming
Search results often blend Ma with better-known people who share his name. He is a different person from Alibaba co-founder Jack Ma and from ByteDance founder Zhang Yiming. The surname Ma is extremely common in China, and Yiming is a popular given name.
At least one low-quality page credits Ma with founding Alibaba in 1999 and holding an $81.5 billion fortune. Those claims describe someone else and are not supported by any source on Ma. Ignore pages that merge the two.
Frequently Asked Questions
What is Simon Yiming Ma’s net worth?
No verified figure exists. Some websites estimate $500 million for 2026, but they cite no documents. The only hard number is the roughly $98.2 million equity value placed on Camelot in its 2013 going-private deal, which measures the company, not Ma personally.
Is Simon Yiming Ma a billionaire?
There is no proof in the public domain that he is. Even the highest online estimate, $500 million, sits well below $1 billion, and no major wealth ranking we found lists him. Claims of billions online usually confuse him with other people named Ma.
What company did Simon Yiming Ma found?
He co-founded Camelot Information Systems, which the Asia Society profile dates to November 2000. It provided enterprise application and financial-industry IT services in China, was listed on the NYSE under the ticker CIS, and was taken private after the 2013–2014 buyout.
Who is Simon Yiming Ma’s wife?
His wife is Heidi Chou. She served as Camelot’s president and was one of three members of the 2013 buyer group, alongside Ma and executive Yuhui Wang. Media profiles also describe her as his co-founder in building the company.
Who is Simon Yiming Ma’s daughter?
Rebecca Ma, who goes by Becca Bloom online, is his daughter. She built a following on TikTok and Instagram, and her 2025 videos drew wider attention to the family’s finances. Her posts do not verify any figure for her parents’ wealth.
Is Jack Ma related to Simon Yiming Ma?
No relationship is documented. Ma is a separate person from Alibaba’s Jack Ma, with a different company and career. The shared surname is common in China, and search engines frequently mix up the two.
Conclusion
Regarding Simon Yiming Ma’s net worth, the most truthful response is that it is unknown. The verified record shows a Camelot co-founder who led a buyout valuing the company’s equity near $98.2 million, while the widely repeated $500 million figure lacks a public source. His private holdings, real estate, and post-buyout earnings are undocumented. Until filings, interviews, or credible reporting fill those gaps, treat any exact figure as an estimate.
