Adira turns three two days after this page was checked and Olympia turns nine twelve days after it, so both ages here have a countdown on them

Serena Williams’ 2 Children: Olympia and Adira

Olympia is the elder by almost six years, and her date is the firmest in the family record. She was born on 1 September 2017, a date her father announced at the time and one that TODAY’s dated file on both girls still carries. Adira is the younger, and her anchor is the announcement her parents published on 22 August 2023, the day Tennis.com and the rest of the tennis press ran the news. Both daughters sit on the same parent branch, Williams and Ohanian, with no stepchildren, no half-siblings and no earlier family to untangle. That is rarer than it sounds in a guide like this one, and it makes the arithmetic clean.

Almost every contradiction you will find in search results is an age problem rather than a fact problem. Pages written when Olympia was six and Adira was a newborn were never recalculated, so they still print a six-year-old and a baby three years on. On 20 August 2026 Olympia is eight and Adira is two, and both numbers are about to move: Adira turns three on 22 August 2026 and Olympia turns nine on 1 September 2026. An age published without a date tells you the year the page was written, not the age of the child.

Both daughters are minors, which draws a hard line under this page. Williams and Ohanian have volunteered two names, two dates, the order they came in and a handful of milestones, and that volunteered set is the whole of what appears here. No school, no routine, no address, no account in a child’s name, and no guessing about which of them might one day pick up a racket. Everything below about careers, ownership stakes and investment attaches to the adults, which is where the evidence actually sits.

Serena Williams’ children at a glance

Two children, two daughters, one parent branch. That has been the complete answer since 22 August 2023, and it is still the complete answer. Forbes, which keeps a maintained record on Williams and last updated it on 20 February 2026, lists two children. Nothing published since names a third, and nothing in the family’s own announcements points toward one.

The table is built around birth dates rather than ages on purpose, because a birth date stays true and an age does not. Olympia’s is documented to the day. Adira’s is fixed to the announcement her parents published, which is the strongest artefact in her public record and the one the tennis press treated as her birth day. Both are unpacked in full below, so you can see exactly what each date proves and what it does not.

Who are Olympia and Adira’s parents?

Serena Williams is their mother. The WTA’s own legends profile sets out what she brought to the family name: 23 Grand Slam singles titles, the most by any woman in the Open Era, 73 tour-level singles titles, 319 weeks at world number one and Olympic singles gold at London 2012. The same profile carries the detail that ties her elder daughter to a famous match, because Williams beat her sister Venus in the 2017 Australian Open final while pregnant with Olympia.

Alexis Ohanian is their father. He co-founded Reddit and now runs the venture firm Seven Seven Six, which is the description Chelsea FC Women used in its own announcement when he joined that club as a minority investor. In the same club statement he describes himself as the founding control owner of Angel City FC. Those are institutional records published by the organisations involved, not press speculation, which is why this guide leans on them.

Venus Williams is the girls’ aunt, and that distinction carries more weight than it looks. It is the single most common identity error attached to this family: pages that describe Olympia as Venus’s daughter have quietly merged two branches of the same household. The WTA record shows the sisters won 14 Grand Slam doubles titles and three Olympic doubles golds together, in 2000, 2008 and 2012. Sharing a surname, a sport and a doubles court does not make a niece a daughter.

Alexis Olympia Ohanian Jr., born 1 September 2017

Olympia was born on 1 September 2017 and goes by her middle name, which is why she appears in most coverage as Olympia Ohanian rather than Alexis. Her father announced her arrival himself with the line that has followed her ever since: “Welcome, Alexis Olympia Ohanian, Jr., we’re so happy to meet you.” TODAY’s file on both daughters carries the same date, which is why it has survived every rewrite of this story. What a child does with an inherited name is a decision that arrives later: Bryan Cranston’s daughter works under her mother’s surname so the credit lands before the connection does.

On 20 August 2026 Olympia is eight. She turns nine on 1 September 2026, twelve days after this check. A profile printing a different number is not disagreeing about her birthday; it is showing you the month it stopped being maintained. If you want to age her yourself at any future point, the only number you need is 1 September 2017.

There is one moment worth keeping, because readers ask about it constantly and it is usually stretched out of shape. In her Vogue farewell essay of 9 August 2022, Williams described a car journey in which an app asked her daughter what she wanted to be when she grew up. Olympia whispered, “I want to be a big sister.” A year later she was one. That is a dated, parent-published moment in the mother’s own words, and it is the right level of detail for a child of this age.

What this guide will not do is turn an eight-year-old into a tennis prospect. TODAY’s file records Williams saying in 2022 that she does not push her daughter, and a photograph on a court is not a career path. Every line published here about Olympia is a date, a name, or something her parents chose to put into public view themselves. That is the whole standard, and it is the reason this section is short.

Adira River Ohanian and the 22 August 2023 anchor

Adira River Ohanian is the younger daughter, and her parents introduced her on 22 August 2023. Tennis.com reported that day that Ohanian had announced the birth, quoting him directly: “I’m grateful to report our house is teaming with love: a happy and healthy newborn girl and happy and healthy mama.” The couple had revealed the pregnancy three months earlier at the 2023 Met Gala, with Williams noting that the invitation had been extended to three of them.

Two separate things are true about that date, and keeping them apart is the difference between a date you can trust and a number you are asked to take on faith. What is documented to the day is the announcement: 22 August 2023, published by her parents and reported the same day. What that announcement establishes about the birth is that it had happened by then, which is why most profiles print 22 August 2023 as her birthday and why this guide uses the same date. The distinction costs you nothing and tells you exactly how firm the number is.

On 20 August 2026 Adira is two. She turns three on 22 August 2026, two days after this check, on the third anniversary of the announcement that introduced her. Her record is thinner than Olympia’s by design rather than by oversight: Olympia is eight, has been photographed courtside since she could sit up and has a football club named in her honour, while almost nothing about a two-year-old belongs in a reference page at all.

Why both ages on this page change within a fortnight

This family is an unusually clean demonstration of why KidsCo dates every age. Adira’s birthday falls two days after the evidence date and Olympia’s falls twelve days after it, so a guide written on 20 August 2026, one written on 25 August 2026 and one written on 5 September 2026 would print three different pairs of numbers while agreeing perfectly about both birth dates. None of them would be wrong. Only the undated ones would be useless.

The third row is the one that trips people up. A magazine writing on 9 August 2022 that Olympia “turns five this month” was rounding a fortnight, not disputing a birth date; her fifth birthday landed on 1 September that year. Where a loose phrase and a documented date appear to disagree, the documented date wins, and the documented date here is the one her father published. That is the ranking this guide applies every time.

Is Olympia really a co-owner of a football club?

She was named in one, and the detail is narrower than the headlines. In 2020 her parents included Olympia in the ownership group behind Angel City FC, the National Women’s Soccer League club in Los Angeles, and Tennis.com recorded her as the youngest owner of a professional sports team at three years old. Sports Illustrated reported the group’s later additions in February 2022, when other families joined on the same footing.

KidsCo treats that for exactly what it is: a parent-led announcement. It fixes a name on a founding ownership group at a dated moment. It does not establish a job, a role at the club, a decision-making seat, a salary or a career, and no financial figure is attached to it here. The club’s own site is where a reader checks what Angel City FC is doing now; the family announcement is where a reader checks what was announced then.

The same test is why this guide separates parents from children throughout. A father’s stake in a football club is a father’s stake in a football club. Anyone comparing how other athlete households handle the same line will find it drawn very differently in the guide to Lionel Messi’s three sons, where three boys in a club’s youth environment are still not professional players, and in the guide to Steph and Ayesha Curry’s four children, where a family brand and four young children are kept firmly apart.

What Serena Williams does now, with dates attached

Williams stepped away from tennis after the 2022 US Open. The WTA states that plainly at the top of her legends profile, and her farewell essay for Vogue is dated 9 August 2022 and written in her own words rather than filtered through a statement. Those two records together are why the retirement question has a clean answer while the “what does she do now” question needs more care.

Several of the current records are first-party, which makes them unusually easy to check. Serena Ventures, the early-stage venture firm she founded, maintains its own live site. Forbes, in a profile last updated on 20 February 2026, describes her as active as an investor through that firm, records the multimedia production company Nine Two Six Productions, launched in 2023, and a licensing deal with the cosmetics brand Wyn Beauty entered in early 2024, and notes a small stake in the Miami Dolphins. Those are dated business records, and they are reported here as dated business records.

Her most quoted current role needs its date most of all. On 3 March 2025 the Toronto Tempo, the WNBA’s first Canadian franchise, announced in an official release that Williams was joining its ownership group alongside Larry Tanenbaum, that she would help shape the club’s jersey designs and merchandise collaborations, and that the team would begin play in 2026 at the Coca-Cola Coliseum. The same release states that her investment was pending final league approval. A dated announcement carrying a stated condition is strong evidence of what was announced. It is not, by itself, proof of a settled 2026 position, and the club’s own site is where a reader confirms the current one.

One further thing belongs on a family page. Williams has spoken publicly about the pulmonary embolism she suffered after an emergency caesarean, an account TODAY traces back to the essay she wrote the following year, and she has used it since to push maternal health up the agenda. That is her account of her own body, told by her, and for a reader who arrived asking about the children it is probably the most useful thing on this page. A parent’s diagnosis reshaping what a family guide can date, and what it has to leave alone, is the same problem faced in Céline Dion’s three sons, where a 2022 announcement changed the whole shape of the coverage.

What Alexis Ohanian does now, including the Chelsea stake

Ohanian’s current record is easier to verify than most, because the institutions publish it themselves. Chelsea FC Women announced him as a minority investor on the club’s own site, describing him as a tech entrepreneur and the founder of Seven Seven Six, and setting out that the existing ownership group remains the controlling shareholder. That is a club setting out its own ownership, which sits at the top of any evidence ladder.

The club then put him on its own We Are Chelsea podcast to mark his first year as a shareholder, which places the deal in 2025 without anyone needing to estimate. In that interview he supplied his own figure, saying that is why he “invested tens of millions of dollars”, and explained that the draw was building the club’s brand in the United States. For a UK reader this is the part of the family story closest to home, because the money landed in the Women’s Super League.

None of it belongs to his daughters, and this guide keeps that line hard. The same separation is applied in the KidsCo guide to Dwyane Wade’s four children and his nephew Dahveon, where a widely repeated count is corrected rather than copied, and in the guide to Michael Jordan’s five children, where adult careers and young twins are handled under completely different rules.

What current Serena Williams family profiles should correct

Four of those five errors are the same mistake wearing different clothes: a dated fact printed as a permanent one. Repairing it takes three moves and no judgement. Attach the date to the claim, state what the record fixes, and stop there. Readers comparing how other two-athlete households are handled will find the same method applied in the KidsCo guide to Steffi Graf and Andre Agassi’s two children, where two adult children are dated to the day rather than described in general terms.

Serena Williams family timeline

Sort those six dates by who they belong to and the record explains itself. Two belong to the children and are fixed. Three belong to the adults and carry conditions or reporting periods. One is a maintenance check on the count itself. Anyone wanting to see the same timeline discipline applied to a larger tennis household will find it in the KidsCo guide to Roger and Mirka Federer’s four children, where two sets of twins are dated to two single days, and in the guide to Kobe and Vanessa Bryant’s four daughters, where a family record had to be rewritten around a fixed and painful date.

Questions people ask about Serena Williams’ two daughters

How many children does Serena Williams have?

Serena Williams has two children, both daughters with her husband Alexis Ohanian: Olympia, born 1 September 2017, and Adira, announced on 22 August 2023. Forbes, whose profile was last updated on 20 February 2026, still lists two children, and no credible source names a third.

What are the birth dates of Serena Williams’ children?

Olympia was born on 1 September 2017, a date her father announced at the time. Adira’s arrival was announced by her parents on 22 August 2023 and the tennis press reported it that day. Those two dates are the durable anchors for both girls.

How old are Olympia and Adira on 20 August 2026?

Olympia is eight and Adira is two. Both numbers move within a fortnight, because Adira turns three on 22 August 2026 and Olympia turns nine on 1 September 2026. That is exactly why this guide publishes birth dates first and ages second.

Who is the father of Serena Williams’ children?

Alexis Ohanian, the Reddit co-founder who now runs the venture firm Seven Seven Six, is the father of both daughters. Chelsea FC Women used that same description in its own announcement when he joined the club as a minority investor.

Does Serena Williams have a son?

No. Both of her children are daughters. The confusion usually comes from pages that merge Serena with her sister Venus, or from profiles written before Adira was announced in August 2023 that were never updated afterwards.

Is Olympia Ohanian a co-owner of Angel City FC?

Her parents included her in the club’s founding ownership group in 2020, when she was three, and the tennis press recorded her as the youngest owner in professional sport. That is an announcement made by adults, not a job, a salary or a role.
