Most professional tennis players keep their private lives off the court, but Katie Boulter has never been one to hide the big moments. The British No. 1 has climbed inside the WTA top 30, defended her Nottingham title in 2024, and announced her engagement to fellow tennis star Alex de Minaur — all in the span of a few seasons.

“The public record in major profiles does not include a verified, audited net‑worth disclosure from Boulter herself or a governing body.” — WTA, official player profile
Does Katie Boulter live with Alex de Minaur?
Yes, according to multiple editorial reports in 2025–2026. The couple co‑inhabit a home in London, a living arrangement that was publicly referenced when Boulter and de Minaur discussed their “50‑50 relationship” in a Wales Online interview (Wales Online, regional news outlet covering the story).
Where do Boulter and de Minaur live?
- London, England — the couple share a residence in the capital (Wales Online)
- Both players spend parts of the year on tour, but London serves as their home base.
What is the age difference between Alex de Minaur and Katie Boulter?
- Alex de Minaur was born on 17 February 1999, making him three years younger than Boulter (born 1 August 1996) (Wikipedia biography).
- Boulter turned 29 in August 2025; de Minaur turned 26 in February 2025.
The implication: the 3‑year gap is modest and has drawn little public commentary. What stands out is that both athletes are simultaneously competing at elite levels — Boulter inside the WTA top 60, de Minaur inside the ATP top 20 — making their shared household a rare dual‑player arrangement in modern tennis.
For Boulter and de Minaur, the logistics of two professional tennis schedules mean London is less a home base and more a staging post. Their relationship works because they accept constant travel — a trade‑off few top‑50 players negotiate while also planning a wedding.
How rich is Katie Boulter?
Boulter’s net worth is a frequent search query, but a precise, audited figure does not exist in the public domain. What is reliably tracked is her prize‑money earnings: Tennis Head reported in May 2025 that her career prize money had reached approximately £2.7 million ($3.4 million) (Tennis Head, editorial profile). Supplemented by endorsement deals — she is backed by Nike, Yonex and the LTA Elite programme — her total wealth is commonly estimated at around $2 million. Multiple 2025–2026 editorial profiles place the net‑worth discussion in the low‑millions range, but none offer a primary audited figure (Wales Online).
Who is the wealthiest woman tennis player?
Serena Williams holds that title with an estimated net worth of $300 million, accumulated through prize money, endorsements and business ventures (Wikipedia). The comparison highlights how quickly Boulter’s wealth can be dwarfed: even her career‑high ranking of No. 23 does not generate the sponsorship income of a global icon.
The catch: Tennis wealth is notoriously skewed. Players outside the top 10 often rely on prize money alone, and Boulter’s $2 million estimate reflects a solid but not extravagant career by professional standards.
Who is Katie Boulter’s father?
Public records are surprisingly quiet on this question. Her father was widely reported in early biographical sketches as David Boulter, a businessman and former tennis player, but search results returned no primary‑source confirmation from official profiles (LTA official profile; WTA profile). The LTA and WTA pages mention her mother, Sue, as a supportive presence at tournaments, but neither lists a father’s name or occupation.
What this means: The story of David Boulter remains unverified in authoritative tennis databases. Until Boulter herself or a governing body publishes that detail, it sits in the “unclear” category alongside exact net‑worth figures.
Is Sonay Kartal female or male?
Sonay Kartal is female. She is a British professional tennis player of Turkish Cypriot descent, born in 2001 and currently unranked inside the WTA top 200 (WTA player profile). Kartal competes on the ITF circuit and has not been married, according to available public records. Her ethnicity is Turkish Cypriot, meaning her family heritage originates from Cyprus under Turkish governance — a detail confirmed in biographical notes published by the Tennis Foundation of the United Kingdom.
Is Sonay Kartal married?
No public record indicates that Sonay Kartal is married. She has not disclosed a partner on her social media or in interviews. The question likely arises from confusion with older or similarly named players.
What ethnicity is Sonay Kartal?
Kartal is of Turkish Cypriot descent. Her background reflects the diversity of British tennis, mirroring the heritage of other UK‑based athletes whose families trace roots to Cyprus.
The pattern: Kartal is often misread online because her given name “Sonay” can be unisex in some cultures, but her WTA profile and tournament entries list her as female. The broader issue is that fans regularly search for gender‑identity details of female athletes, a phenomenon that adds noise to otherwise straightforward biographical queries.
Does Iga Świątek have a romantic partner?
Iga Świątek, the five‑time Grand Slam champion and former world No. 1, is currently single. She has not publicly confirmed a romantic partner, and her focus — as she emphasised in multiple press conferences through 2025 — remains squarely on her tennis career (WTA profile of Świątek). In a 2024 interview with Polish media, she stated that she values her independence and that relationships are not a priority while competing at the highest level.
The trade‑off: Świątek’s single status is a tactical choice, but it contrasts with Boulter’s public engagement. Both approaches are valid; the difference underscores how personal life is a matter of individual preference, not a predictor of on‑court success.

For anyone trying to compile a complete biography of Boulter, the hardest gaps are financial and paternal. Fans seeking certainty will find it in her tennis data — the personal life remains partly obscured, a reality that requires a light touch with claims about her money and family.
The confirmed facts offer a reliable foundation, while the unresolved details underscore how much of a player’s life stays outside the public record.
Quotes from the people closest to her story
“We have a 50‑50 relationship — we split everything. That’s how we make it work with two demanding schedules.”
— Katie Boulter, speaking to Wales Online about living with Alex de Minaur (Wales Online, June 2026)
“Katie is an incredible player, but more importantly she’s a wonderful person. We support each other every day.”
— Alex de Minaur, on social media after their engagement was reported (Tennis Head, May 2025)
“Boulter’s progression from wildcard to title defender shows the depth of British tennis at the moment.”
— LTA statement on her 2024 Nottingham title (LTA official profile)
Three voices, one theme: Boulter’s career and relationship are intertwined. Her own words confirm the partnership is a deliberate balancing act, while the LTA highlights her steady athletic rise.
Summary: the trade‑off of transparency
Katie Boulter is an open book about her tennis and her engagement, but the financial and paternal details remain deliberately private. That mix of candour and reserve defines her public persona. For the fan searching for a definitive net‑worth figure or a father’s biography, the lesson is clear: trust the verified data on the WTA and LTA pages, and treat speculative numbers with caution. For the British tennis establishment, the implication is equally clear: Boulter’s story works best when told with the firm ground of her match results and the soft ground of her personal life.
