Seven facts that define Katie Boulter’s career and personal life at a glance:

The pattern here: a player whose public identity is now inseparable from her partnership with de Minaur, yet whose individual ranking trajectory tells the more interesting story.

Are Katie Boulter and Alex de Minaur still together?

Yes — the couple married in July 2026. The BBC reported that Boulter and de Minaur celebrated their wedding in Tuscany, Italy, earlier that month. The engagement had been announced in December 2024 via an Instagram post captioned “We’ve been keeping a small secret.”

How did Katie Boulter meet her fiance?

They met through mutual tennis friends and began dating in 2020, according to BBC Sport. At the time, Boulter was 24 and de Minaur was 21. By the time of their engagement in 2024, the couple had been together nearly five years.

What is the age gap between Alex de Minaur and Katie Boulter?

Three years. Boulter was born 1 August 1996 and de Minaur was born 17 February 1999, as confirmed by WTA and Wikipedia.

Where do Alex de Minaur and Katie Boulter live?

The couple splits time between London, England, and Sydney, Australia. Boulter trains at the National Tennis Centre in London while also maintaining a home in Sydney with de Minaur. This bi-hemisphere arrangement is common among tennis professionals with partners from different countries.

The pattern: three-year age gap, two countries, one shared calendar. For a dual tennis career household, the real question is how they manage court time during the Australian summer and European clay season.

What is Katie Boulter’s net worth?

Katie Boulter’s net worth is estimated at $1–5 million, primarily from prize money and endorsements. Her career prize money exceeded $2 million as of the end of 2024, according to the WTA. A 2022 report from MyLondon estimated her net worth at roughly $1 million, with career prize money of about $942,556 at that time — though this figure is now outdated given her subsequent titles and ranking rise.

Boulter has endorsement deals with Nike (apparel and footwear) and Yonex (racquets and equipment), both confirmed in her WTA profile. These sponsorships, combined with tournament winnings from her WTA 250 titles at Nottingham and the WTA 500 title in San Diego, form the bulk of her earnings.

What illness does Katie Boulter have?

Katie Boulter suffered a stress fracture in her back in 2019, an injury that sidelined her for several months. BBC Sport reported that the injury forced her to miss Wimbledon that year and required an extended rehabilitation period. Boulter has since said of the experience: “It was a tough period, but I came back stronger.”

She has also dealt with shoulder injuries, common among tennis players who generate significant power from their serve. Additionally, Boulter has spoken publicly about the mental health challenges inherent in professional tennis, advocating for better support systems within the sport. No chronic or recurring illness has been reported beyond these injury-related setbacks.

What this means: Boulter’s career narrative is one of injury resilience rather than ongoing medical limitation. The 2019 back injury, which could have derailed a less disciplined athlete, instead preceded her best seasons.

Where does Katie Boulter live now?

Katie Boulter primarily lives in London, England, where she trains at the National Tennis Centre in Roehampton. The LTA lists her hometown as Leicester, but she has spent most of her professional career based in London for training access. She also shares a home in Sydney, Australia, with her husband Alex de Minaur, which serves as her base during the Australian swing of the WTA calendar.

For British tennis fans wondering whether Boulter still considers the UK home — the answer is yes. London remains her primary residence, with Sydney functioning as a second home tied to the ATP/WTA season cycle.

Does Katie Boulter have a father?

Who is Katie Boulter’s father?

Yes, her father is David Boulter, a former tennis player himself. The LTA confirms her mother is Sue Boulter, who also played county-level tennis and represented Great Britain at the junior level. Katie has a younger brother named Jack. BBC Sport noted that her mother made several Great Britain appearances and later became a tennis coach.

The implication for her career path: growing up with two tennis-involved parents gave Boulter early access to coaching and competition, a pattern common among successful British tennis players who emerged from the mid-2010s era.
