Introduction

Ken Griffin is an American hedge fund manager and billionaire.

Griffin is the chief executive of the investment firm Citadel, which he founded in 1990.

Citadel operates with an estimated $32 billion in investment capital.

Ken Griffin’s net worth is estimated to be $28 Billion. 

 

Early Life 

Kenneth Cordele Griffin was born on the 15th of October, 1968, in Daytona Beach, Florida.

In high school, he excelled academically and was president of his math club.

In 1986, Griffin started to invest during his freshman year at Harvard University. 

During his second year at Harvard, he started a hedge fund focused on convertible bond arbitrage.

The fund was capitalized with $265,000 from friends and family, including money from his grandmother. 

 

Career 

After graduating from Harvard College in 1989, Ken Griffin began working with the founder of Glenwood Captial Investments, Frank Meyer. 

Meyer gave Griffin $1 million in capital from his company to trade, and Griffin made a 70% return that year. 

A year later, he started Citadel LLC, a hedge fund and financial services company helped by Meyer’s contributions. 

Entering the 2000s, Griffin founded Citadel Securities and became the youngest person on the Forbes 400, worth $650 million at 34. 

However, inspired by the wealthiest people in the world, this was only the beginning for Ken Griffin. 

 

Making Millions

From 2003 to 2009, Ken Giffin was the leading investor in Aragon Global Management, a hedge fund his then-wife ran. 

Griffin took a hit during the 2007-2008 financial crisis and, at the time, barred his investors from withdrawing money. 

While this move was met with criticism, as he was losing hundreds of millions a week, his company was able to bounce back. 

By 2009, Citadel had rebounded with a 62% return after dropping by 55% the previous year. 

Giffin earned $900 million from his company in 2009, which skyrocketed to $1.4 billion in 2014. 

By 2020, his earnings had increased even further to $1.8 billion, up from $1.5 billion the previous year. 

Now one of the wealthiest people in America, Ken Giffin formed Griffin Catalyst in 2023 as a platform for his philanthropic ventures. 

Focusing on science and education, this organization has partnered with many others to benefit those who need it most. 

Griffin also often donates to political campaigns, including the campaigns of Marco Rubio, Rahm Emanuel, and Bruce Rauner. 

 

Griffin’s Philanthropy

Ken Griffin has donated hundreds of millions to various causes throughout his career and doesn’t seem keen on stopping. 

Notably, Giffin has worked with the Bill Gates Foundation to help promote charter schools across the U.S. 

In 2014, he donated $150 million to Harvard University’s financial aid program. 

Griffin donated $21.5 million to the Field Museum of Natural History and its Griffin Dinosaur Experience. 

He then gifted the Museum of Science and Industry $125 million, prompting it to be renamed the Kenneth C. Griffin Museum of Science and Industry. 

Griffen also supports the arts, donating $19 million to the Art Institute of Chicago and $40 million to the Museum of Contemporary Art. 

During the COVID-19 pandemic, he donated $2 million to Weill Cornell Medicine and $2.5 million to Chicago Public School. 

In 2022, Griffin created the Ukraine Math and Science Achievement fund with $3 million to support Ukrainian refugees at Cambridge. 

Soon after, he donated $5 million to start the Miami Disaster Resilience Fund, which would help prepare the city for hurricanes. 

Most recently, he has partnered with Eric Schmidt to launch Convergent Research, a scientific research project. 

Around the same time, he donated $25 million to the Nicklaus Children’s Hospital and pledged $400 million to the Sloan Kettering Cancer Center.

Teresa Heinz Kerry Net Worth

Teresa Heinz Kerry Net Worth
Net Worth:$750 Million
Age:86
Born:October 5, 1938
Gender:Female
Height:1.64 m (5 ft 5 in)
Country of Origin:Mozambique
Source of Wealth:Entrepreneur
Last Updated:Jul 21, 2025

Introduction

Teresa Heinz Kerry is a well-established businesswoman and philanthropist with an estimated net worth of $750 Million. 

 

Wrongful Death Lawsuit

Following the death of her first husband, Senator John Heinz, in 1991, Kerry filed a lawsuit for wrongful death against the owners of two aircraft involved in a mid-air collision. The plane her husband was travelling in collided with a Bell 412 helicopter, killing everyone who was on board both the aeroplane and the helicopter. Following their investigation of the crash, the National Transportation Safety Board determined that the pilots of both aircraft were at fault due to errors in judgment.

In 1997, Kerry successfully sued both the owners of the helicopter and the plane, Piper Aerostar, and the lawsuit was settled for $15 million in Kerry’s favor. $3 million was given directly to Kerry in her role as co-executor of the Heinz estate, and the remaining $12 million was split between Kerry and her two sons.

 

Chinese Investment Firm Controversy

Although not strictly a legal issue, Kerry found herself in the spotlight in 2021 when government filings revealed that she had an interest in Chinese investment firms. This was an issue as her husband, John Kerry, was the U.S. climate envoy at the time and regularly negotiated with China on climate cooperation. The former U.S. chief ethics lawyer, Richard Painter, stated that it could create legal and ethical issues as Chinese officials could hold the investments hostage.

According to the Office of Government Ethics, Kerry has an interest of at least $1 million in Teng Yue Partners. This hedge fund specialises in Chinese equity investments, though the assets were held in trust and not managed by Kerry or her husband. Despite the speculation, there’s no public record showing that Kerry was asked to sell her investments, and John Kerry continued his work as the U.S. climate envoy.

 

Philanthropy

Although Kerry chose not to take a leadership role at Heinz, she did take the lead in the family’s philanthropic activities. She oversees the Heinz Endowments and the Heinz Family Philanthropies, two of the largest private charitable foundations, whose annual grants total more than $90 million. The Heinz philanthropic donations support a range of diverse initiatives, with a focus on environmental conservation, women’s issues, health, education, and community development.

 

Alliance for Health homes

With environmental issues at the heart of Kerry’s philanthropic endeavors, she has launched several green initiatives, including the Alliance to End Childhood Lead Poisoning in 1990. It later changed its name to the Alliance for Healthy Homes, with the sole aim of preventing lead poisoning in children throughout the United States.

In 1993, Kerry co-founded Second Nature with her husband, U.S. Senator John Kerry, environmental scientist Dr. Anthony D. Cortese, and Bruce Droste, an environmental educator. Second Nature is a nonprofit dedicated to making sustainability a core part of campus life, collaborating with U.S. colleges to integrate sustainability into research, teaching, and campus operations.

 

Women’s Retirement Initiative

In addition to focusing on the environment, Kerry has founded charities that support the financial security of women’s futures. In 1997, Kerry launched the Women’s Retirement Initiative. The following year, she founded the Women’s Institute for a Secure Retirement (WISER), which has since become a leading advocate for policies that benefit older women facing financial insecurity.

Kerry has acknowledged the roots of the Heinz company, which was founded in Pittsburgh, and has gifted the city numerous grants through Heinz Endowments. Heinz has helped to improve many aspects of the city, including parks and concert halls. For example, in 2021, they donated over $30 million to support community projects, including Bike Share Pittsburgh, which received $750,000 to purchase electric bikes. $1.75 million was allocated to the historic New Granada Theater in the Hill District, allowing it to be renovated and restored.

Kerry’s philanthropic endeavors have not gone unnoticed. In 2003, she received the Albert Schweitzer Gold Medal for Humanitarianism. In 2007, the Carnegie Medal of Philanthropy was awarded to her on behalf of the Heinz family, recognizing her impact on the institutions and initiatives she had helped establish.

 

Real Estate

Kerry is the proud owner of a six-floor, $7 million townhouse in Boston’s Beacon Hill neighborhood. She and her husband also own a $5 million ski retreat in Idaho, a $4 million estate in Pennsylvania near their home base in Pittsburgh, and a $5 million home in Washington, D.C.’s Georgetown neighborhood.

Net Worth:$28.2 Billion
Age:67
Born:August 11, 1957
Gender:Male
Height:Unknown
Country of Origin:Japan

Last Updated:Jul 21, 2025

Introduction   

Masayoshi Son is a Japanese billionaire entrepreneur, investor, and philanthropist with an estimated net worth of $28.2 Billion. 

 

Net Worth History

YearNet Worth
2016$11.7 Billion
2017$21.2 Billion
2018$22.7 Billion
2019$21.6 Billion
2020$16.6 Billion
2021$45.4 Billion
2022$21.3 Billion
2023$22.4 Billion
2024$32.7 Billion
2025$29.4 Billion

Masayoshi Son’s net worth is heavily tied to his 29.7% stake in SoftBank, the Japanese conglomerate that centers around technology investments. Back in 2016, Son’s fortune was estimated to be approximately $11.7 billion. Between 2017 and 2019, the amount typically ranged between $21.2 billion and $22.7 billion, before declining to $16.6 billion in 2020. 

Son experienced a sharp increase in his wealth in 2021, which was one of the best-performing years for SoftBank’s Vision Fund. Midway through the year, Vision Funds 1 & 2 reached a combined value of $154 billion, with the company recording $45.9 billion in annual profits. It was the most profitable year in SoftBank’s history, leading to Masayoshi’s net worth increasing to an estimated $45.4 billion. 

This was a somewhat inflated sense of wealth, as the estimate was revised to roughly $21.3 billion the following year. In recent years, SoftBank has invested billions in AI projects, including Stargate, OpenAI, MGX, and Oracle. Masayoshi’s net worth shot up again to $32.7 billion in 2024. However, as of this year, he is worth approximately $28.2 Billion.

 

SoftBank Compensation

YearTotal Earnings (JPY)USD
2019608,000,000$4,600,000
2020635,000,000$4,800,000
2021647,000,000$4,900,000
2022574,000,000$4,300,000
20231,281,000,000$9,600,000
Totals3,745,000,000$28,200,000

Although Masayoshi’s wealth is predominantly held through his stake in SoftBank, he also earns several million dollars annually as the company’s CEO. The above data regarding Masayoshi Son’s annual compensation comes directly from SoftBank’s official ESG disclosures. For the last several years, his annual salary has remained at ¥120 million, equivalent to approximately $808,000 USD. 

However, his additional earnings, and the biggest contributor to his yearly compensation, come from various performance bonuses and stock options. From 2019 to 2022, his total annual compensation ranged between $4.3 million and $4.9 million. His highest recorded year was 2023, when he received ¥1.28 billion in compensation, equivalent to approximately $9.6 million. 

Between 2019 and 2023, based on the ESG disclosures, Masayoshi Son earned a total compensation of $28.2 million from SoftBank.

Alexis Ohanian Net Worth

Alexis Ohanian Net Worth
Net Worth:$100 Million
Age:42
Born:April 24, 1983
Gender:Male
Height:1.96 m (6 ft 5 in)
Country of Origin:Canada
Source of Wealth:Entrepreneur
Last Updated:Jul 21, 2025

Introduction

Alexis Ohanian is an American Internet entrepreneur and investor with an estimated net worth of $100 Million.

 

Reddit

Over several decades, Ohanian has created numerous successful companies in tech, investing, and sports. In 2005, he co-founded Reddit with his University of Virginia roommate, Steve Huffman, and the two pitched the idea to venture capital firm Y Combinator. They were fortunate to secure $12,000 in seed funding from the VC firm, which enabled them to launch Reddit. Within 12 months, Reddit was sold to Condé Nast for a reported $10-$20 million. Ohanian stayed with Reddit until 2009, returning briefly in 2015 as their Executive Chairman until his resignation in 2020.  

 

Initialized Capital

Inspired by his own startup journey, Ohanian teamed up in 2011 with Harjeet Taggar and Garry Tan of Y Combinator and launched Initialized Capital, a venture capital firm. Ohanian and his co-founders wanted to support software and tech founders at the seed stage of their businesses with mentorship and access to influential networks within Silicon Valley. Over ten years, Initialized Capital raised more than $3.2 billion in assets and has invested in 23 companies, including Coinbase, Cruise Automation, Instacart, and CoinTracker.

 

Seven Seven Six

Ohanian left Initialized Capital in 2020 to set up another venture capital firm, Seven Seven Six (776). He wanted to leverage his experience and extensive network of contacts to help launch and scale early startups, many of which were still just ideas. Ohanian scaled 776 rapidly, with a portfolio of 38 companies, managing $750 million in assets. 

 

Angel City FC Acquisition

In 2020, Ohanian became the largest shareholder and founding controlling owner of Angel City FC (ACFC). The professional women’s soccer team is based in Los Angeles and was established by actress Natalie Portman, venture capitalist Kara Nortman, and entrepreneur Julie Uhrman. In July 2024, Walt Disney CEO Bob Iger and his wife Willow Bay acquired a controlling stake in the club, valued at $250 million. Ohanian played a key role in the club’s growth and remains on the club’s board.

 

Los Angeles Golf Club Acquisition

Continuing his interests in sport, Ohanian was named as the principal Owner of the Los Angeles Golf Club (LAGC) in June 2023. The club’s ownership group also includes Ohanian’s wife, her sister Venus Williams, and Michelle Wie West. Ohanian’s key aim with the club is to make golf more accessible and to blend the sport with technology and entertainment to appeal to a new and more diverse fan base.

 

Athlos Track & Field

In 2024, Ohanian and the American Olympic Track and Field Champion Gabby Thomas launched Athlos, a women-only professional track and field event. He was motivated by the lack of lucrative opportunities for women in track and field outside of the Olympics. The first meet was held at New York’s Icahn Stadium in September of that year and featured 36 top competitors.

The meet had a record-breaking $663,000 prize purse, with $60,000 awarded to each event winner to highlight the value of women’s athletics. Ohanian was responsible for the event being shown on platforms like ESPN+, YouTube, and DAZN, to ensure that Athlos reached millions of viewers and attracted new fans to the sport. He also introduced distributing 10% of all commercial income evenly among the athletes, which was unusual and possibly a first, as funds are usually distributed based on performance or contract.

 

Chelsea F.C. Investment

Following his success with ACFC, in May 2025, Ohanian bought a 10% stake in Chelsea Women’s Soccer Club in the United Kingdom. The investment was worth around £20 million ($26.86 million) and valued the club at £200 million ($268.57 million), making it one of the most valuable women’s soccer clubs in the world. He said his goal is to help Chelsea FC Women’s Club become a global brand and to use his expertise and network to boost the club’s international profile, particularly in the United States.

Ohanian has consistently shown his passion for backing tech founders and his commitment to giving women’s sport the recognition and investment it has lacked for so many years.

 

Bored Ape Yacht Club Lawsuit

In 2023, Ohanian was named in a class action lawsuit along with several other high-profile celebrities, including his wife, Gwyneth Paltrow, Madonna, and Snoop Dogg. Investors in Yuga Labs’ Bored Ape Yacht Club (BAYC) non-fungible tokens (NFTs) and Apecoin alleged that the celebrities, including Ohanian and Williams, fraudulently promoted NFTs.

However, the celebrities had never revealed their financial interests or how much compensation they would get as a result of their involvement. The case alleged that the celebrities who had endorsed the NFTs were benefiting from the inflated value. Yuga Labs stated that the claims were false, and as of today, the case is ongoing. 

 

Real Estate

Brooklyn Condo

In 2011, Ohanian purchased a two-bedroom, 1,385-square-foot apartment in Brooklyn Heights for $1.245 million. Before he sold the unit, Alexis had been renting it out to people for $7,500 per month since 2016. In May 2022, he listed the apartment for sale at $2.3 million. It was scooped up in December that year for $2.05 million.

 

Highlights 

Here are some of the best highlights of Alexis Ohanian’s career: 

  • Co-founder and executive chairman of Reddit
  • Ohanian launched Breadpig (2007)
  • Ohanian spoke at TED about a whale named Mister Splashy Pants (2009)
