Looks like it's a secret, but I doubt it goes to his wife.
There is no definitive public information specifying who will own the Dallas Cowboys after Jerry Jones passes away. However, based on available sources, it’s reasonable to infer that ownership is likely to remain within the Jones family due to their deep involvement in the franchise’s operations. Jerry Jones, who purchased the team in 1989, has integrated his family into key executive roles: his son Stephen Jones serves as the chief operating officer, executive vice president, and director of player personnel; his daughter Charlotte Jones is the executive vice president and chief brand officer; and his son Jerry Jones Jr. is the chief sales and marketing officer/vice president. This family-centric management structure suggests a succession plan that keeps control within the family.
While no explicit will or succession document has been publicly disclosed, the Jones family’s significant financial stake—Jerry Jones’ net worth is estimated at $16.6 billion, largely tied to the Cowboys’ $10.3 billion valuation—further supports the likelihood of the team staying under family control, possibly through a trust or direct inheritance to his children.
Without a specific announcement from Jones or legal documentation, this remains speculative but grounded in the family’s entrenched roles and the franchise’s value to their legacy. If you’d like, I can search for any recent developments or posts on X to see if new information has emerged.
