Tiffany Stewart: Her Life With Mark Cuban, Career, Family and What We Know About Her Net Worth

ByAnam Ilyas

For much of her public life, Tiffany Stewart has been known primarily as Mark Cuban’s wife. But her story began before Cuban became a billionaire, when she was working in advertising sales and the two met at a Dallas gym in 1997.

More than two decades later, their relationship has remained largely outside the celebrity spotlight. They married in 2002, raised three children and, despite Cuban’s highly public career, Stewart has maintained a comparatively private profile. In 2025, Cuban made his final scheduled appearance on Shark Tank after saying he wanted to spend more time with his family, bringing renewed attention to the family life he shares with Stewart.

The details that are publicly known paint a picture of a woman who had her own working life before marriage and later became involved in family and charitable activities.

How Did Mark Cuban Meet Tiffany Stewart?

The answer goes back to 1997 in Dallas, Texas. A 2000 Forbes profile identified Stewart as Cuban’s girlfriend and described her as a 28-year-old advertising saleswoman whom he had met at a gym three years earlier. More recently, Good Housekeeping likewise reported that the pair met at a Dallas gym in 1997, with Stewart around 25 at the time. (Forbes)

The timing is significant because Cuban’s life was changing rapidly. In 1999, Yahoo acquired Broadcast.com, the internet company he had co-founded with Todd Wagner, in a deal valued at about $5.7 billion. By 2000, Cuban had purchased the Dallas Mavericks and was living a dramatically more affluent life. (Forbes)

Stewart, however, was still working. Contemporary reporting described her driving a Honda to her advertising job and regarding the couple’s enormous Dallas home as impractical. That contrast became one of the most frequently reported details about her early relationship with Cuban. (Yahoo)

Tiffany Stewart and Mark Cuban’s Marriage

The couple dated for roughly five years before marrying on September 21, 2002, in Barbados. According to the Associated Press report published through ESPN, the wedding was originally planned for Jamaica but was moved because of concerns surrounding Tropical Storm Isidore. About 20 family members and friends attended the private ceremony. (ESPN)

At the time, Cuban was already extraordinarily wealthy. The AP reported that Forbes valued his net worth at $1.3 billion in 2002. Today, Forbes estimates Cuban’s real-time net worth at $6.8 billion, illustrating just how dramatically his financial position changed over the course of their marriage. (ESPN)

In 2024, Cuban also offered a rare personal story about his relationship on the Club Shay Shay podcast. He recalled taking Stewart to White Castle before their marriage and joking that eating a burger there was his test of whether she loved him. The story provided another glimpse into the private relationship behind their decades-long marriage. (iHeart)

Tiffany Stewart’s Career: What Does She Do?

Before marrying Cuban, Stewart worked in advertising sales. Forbes described her as an advertising saleswoman in 2000, while later profiles have referred to her as an advertising executive. (Forbes)

Her professional life eventually became less visible publicly. A 2019 profile by DFWChild, which interviewed Stewart directly, documented her involvement in charitable activities. At the time, she was involved with Hoops ‘n Hopes and served on the board of the Mavs Foundation, where she participated in decisions concerning grant recipients. (DFWChild)

There is limited reliable reporting documenting her exact current occupation in 2026. It is therefore more accurate to describe her as a former advertising professional who has also been involved in philanthropy rather than claim that she currently holds a specific corporate position.

Tiffany Stewart Age

One frequently repeated online detail is a January 1, 1970 birth date, but I could not independently verify that date through a strong primary or major-journalism source.

What can be verified is that Forbes described Stewart as 28 in October 2000, while Good Housekeeping has reported that she was 25 when she and Cuban met in 1997. Those contemporary age references place her in her mid-50s in 2026. (Forbes)

That is a more defensible answer to the search query “Tiffany Stewart age” than presenting an unverified exact birthday as fact.

Tiffany Stewart Ethnicity and Religion: Is She Jewish?

There is surprisingly little reliable public information about Stewart’s ethnicity or religious beliefs.

Some secondary celebrity-biography websites describe her ethnicity as white or Caucasian, but I did not find a strong primary source in which Stewart herself publicly identifies her ethnicity. For that reason, her ethnicity should be treated as not independently confirmed.

The same caution applies to the question “Is Tiffany Stewart Jewish?” Mark Cuban is publicly known to be Jewish, but that does not establish his wife’s religion. I found no reliable source in the research reviewed that confirms Stewart as Jewish, so it should not be presented as fact.

Tiffany Stewart Net Worth

The frequently searched phrase “Tiffany Stewart net worth” produces various numbers online, but there is no reliable public financial disclosure establishing Stewart’s individual net worth.

That distinction matters because Mark Cuban’s wealth is not automatically Tiffany Stewart’s personal net worth. Forbes currently estimates Cuban’s fortune at $6.8 billion, but that figure describes Cuban, not Stewart. (Forbes)

A trustworthy biography should therefore say that Tiffany Stewart’s personal net worth is not publicly known rather than repeat an unsupported celebrity-site estimate.

Family Life With Mark Cuban

Stewart and Cuban have three children: daughters Alexis and Alyssa and son Jake. Their first child was born in 2003, Alyssa followed in 2006 and Jake was born in 2010. (People.com)

Family has increasingly featured in Cuban’s public comments in recent years. He announced in 2023 that he planned to leave Shark Tank after its 16th season, explaining that his children were teenagers and he wanted more time with them. His final episode aired in May 2025. (People.com)

That shift also gives useful context for Stewart’s current public image: while Cuban remains active in business, including Cost Plus Drugs and sports investments, Stewart continues to maintain a considerably lower public profile. (Forbes)

A Note About Tiffany Haddish and William Stewart

Searches for Tiffany Stewart sometimes become mixed with information about Tiffany Haddish. They are different people.

William Stewart was Tiffany Haddish’s former husband; Haddish married William Stewart in 2008 and their divorce was finalized in 2013. He has no known connection to Mark Cuban’s wife Tiffany Stewart. (Courthouse News)

Tiffany Stewart’s story is less about building a public celebrity career and more about the unusual timeline surrounding a private life that unfolded alongside one of America’s most recognizable entrepreneurs. She met Mark Cuban when she was working in advertising, stayed with him through the transformation of his fortune, married him in a small Barbados ceremony in 2002 and helped raise their three children. Her philanthropic work has also appeared in Dallas-area reporting, although much of her life remains outside the public record. (DFWChild)
