Introduction
The net worth of Masayoshi Son and Greg Hayes attracts attention because both executives have played important roles in major global businesses. Son is a Japanese entrepreneur and the founder of SoftBank Group, an investment company with significant interests in technology and artificial intelligence. Hayes is an American business executive best known for leading United Technologies Corporation and RTX, a major aerospace and defence company.
However, their personal fortunes differ considerably in scale. Masayoshi Son has accumulated billionaire wealth through his ownership interests and investments in technology companies. Greg Hayes has built substantial wealth through executive compensation, shareholdings and a long career in corporate management.
When researching Masayoshi Son and Greg Hayes net worth, it is important to distinguish verified financial information from estimates. A person’s net worth includes assets and investments minus liabilities, whereas an executive’s annual salary represents only one component of their overall financial position.
This article explores their estimated fortunes, professional achievements, income sources and the business decisions that have shaped their financial standing.
Masayoshi Son Net Worth in 2026
Who Is Masayoshi Son?
Masayoshi Son was born in Japan in 1957 and later studied in the United States at the University of California, Berkeley. He founded SoftBank in 1981, initially focusing on software distribution before expanding into telecommunications, technology and international investment.
Son became one of Japan’s most prominent entrepreneurs by identifying opportunities in businesses that could benefit from technological change. His investment decisions have helped shape his reputation as an ambitious, forward-looking business leader.
How Much Is Masayoshi Son Worth?
In June 2026, Forbes estimated Son’s wealth at approximately $80 billion for its annual Japan’s 50 Richest ranking. A separate Forbes real-time profile subsequently displayed an estimate of $83.7 billion as of 10 September 2026. These figures reflect different valuation dates and should not be treated as a fixed amount.
His fortune places him among the world’s wealthiest businesspeople and reflects the market value of his investments and ownership interests, rather than cash held in a bank account.
Main Sources of Masayoshi Son’s Wealth
1. SoftBank Group Ownership
SoftBank is the foundation of Son’s business empire. As its founder and leading executive, he has benefited from the company’s expansion into telecommunications, internet services, technology investments and artificial intelligence.
Changes in SoftBank’s share price can significantly influence estimates of his personal wealth.
2. Technology Investments
Son has invested in businesses operating across several technology sectors, including digital commerce, financial technology, transport and software.
Some investments have generated substantial gains, while others have experienced major losses. This mixture of successes and setbacks demonstrates the risks associated with backing rapidly growing businesses.
3. Artificial Intelligence and Advanced Computing
Artificial intelligence has become a central theme in SoftBank’s investment strategy. The company has pursued opportunities involving AI infrastructure, semiconductor technology and businesses developing advanced computing systems.
These investments may create considerable long-term value, although their eventual returns depend on commercial demand, competition, financing costs and the ability of individual businesses to achieve sustainable growth.
Greg Hayes Net Worth in 2026
Who Is Greg Hayes?
Gregory J. Hayes is an American corporate executive who became widely recognised through his leadership of United Technologies Corporation and Raytheon Technologies, subsequently renamed RTX.
He joined United Technologies in 1999 and held several senior financial positions before becoming its chief executive in 2014. His experience in finance and corporate management helped prepare him to oversee complex industrial operations and major strategic changes.
Hayes became chief executive of Raytheon Technologies following the 2020 merger of United Technologies and Raytheon Company. He later served as executive chairman before leaving that position in April 2025.
How Much Is Greg Hayes Worth?
Unlike Son, Hayes does not have a consistently published billionaire-style fortune estimate from Forbes that can be compared directly with Son’s ranking.
Commercial financial-data services have published estimates of his wealth based partly on reported shareholdings. For example, GuruFocus estimated his net worth at at least $114 million in July 2026, while Benzinga reported an estimate of $169 million in May 2026. These figures use different methodologies and should be regarded as indicative estimates rather than audited statements of his complete personal finances.
A cautious assessment is therefore that Hayes has accumulated wealth worth tens or potentially hundreds of millions of dollars, but his exact net worth is not publicly established.
Main Sources of Greg Hayes’ Wealth
1. Executive Compensation
Hayes earned substantial compensation during his years in senior management. His remuneration included a base salary, annual incentives and long-term awards linked to company shares.
RTX’s 2024 proxy statement reported approximately $14.6 million in total compensation for Hayes for that year, reflecting his transition from chief executive to executive chairman. This was compensation reported under corporate disclosure rules, not a calculation of his personal net worth.
2. Shares and Investments
Shareholdings can form an important part of an executive’s wealth. The value of publicly traded shares changes with market conditions, and reported holdings do not necessarily represent money that has been realised through a sale.
Financial-data services use disclosed shareholdings and market prices to estimate part of Hayes’ financial position. However, such calculations may not capture all private investments, liabilities or other assets.
3. Long-Term Corporate Leadership
Hayes’ career has extended across decades of senior financial and executive responsibilities. His leadership roles brought opportunities to earn substantial compensation and participate in long-term incentive programmes.
These earnings help explain how an executive can accumulate significant personal wealth without owning a business that makes up a large proportion of a global billionaire’s fortune.
Masayoshi Son and Greg Hayes Net Worth Compared
Understanding the Difference in Their Fortunes
The financial gap between Son and Hayes is substantial. Son’s estimated fortune is measured in tens of billions of US dollars, while Hayes’ publicly reported wealth estimates are measured in millions.
| Financial factor | Masayoshi Son | Greg Hayes |
|---|---|---|
| Main source of wealth | Technology ownership and investments | Executive compensation and shareholdings |
| Primary business association | SoftBank Group | United Technologies and RTX |
| Estimated wealth in 2026 | Approximately $80–84 billion at selected valuation dates | Third-party estimates range from $114 million to $169 million |
| Main financial influence | Technology valuations and investment performance | Stock holdings, compensation and investment performance |
| Publicly confirmed exact net worth | Not available as a fixed figure | Not publicly established |
These estimates are not perfectly comparable because they come from different sources and valuation dates. Nevertheless, they illustrate the difference between the wealth of a major technology investor and that of a highly compensated corporate executive.
Why Is Masayoshi Son Much Wealthier?
Son’s financial position reflects his ownership interests in a large technology investment group. When companies in which SoftBank invests increase in value, the market value of relevant assets and Son’s own fortune can rise considerably.
Hayes’ earnings, by contrast, have primarily come from executive remuneration and financial investments accumulated throughout his career. Even substantial salaries and share awards generally do not produce the same wealth as a large ownership stake in a successful investment business.
The Importance of Equity Ownership
Equity ownership can create wealth on a scale that salaries alone rarely achieve. A founder who retains valuable shares may benefit from years of business growth without receiving all that value as cash income.
This distinction helps explain why entrepreneurs and major shareholders often appear much wealthier than executives who have managed equally important organisations.
The Role of Risk in Their Financial Success
Masayoshi Son’s High-Risk Investment Strategy
Son has built his reputation around ambitious investments and a willingness to commit substantial capital to emerging industries. This strategy can deliver significant rewards when a business grows rapidly, but it can also expose investors to considerable losses.
SoftBank’s experience with WeWork demonstrated the dangers of investing heavily in a business whose valuation and commercial prospects later deteriorated. Conversely, successful investments in major technology companies have contributed significantly to Son’s reputation and wealth.
His recent emphasis on artificial intelligence introduces further opportunities alongside substantial financial commitments. The eventual outcome will depend on whether investments in computing infrastructure and AI businesses generate sustainable commercial returns.
Greg Hayes’ Approach to Corporate Management
Hayes’ career demonstrates a different way of creating value. Rather than relying primarily on venture-style investments, he managed large industrial businesses with established customers, complex production systems and substantial engineering requirements.
The merger that created Raytheon Technologies was intended to combine complementary aerospace and defence capabilities. Such transactions can create opportunities for efficiency and growth, but they also require careful integration, financial planning and operational management.
Balancing Growth and Financial Discipline
Both executives operated in environments where financial decisions carried significant consequences. Son’s investment strategy required assessing the uncertain future value of technology businesses. Hayes’ leadership required balancing investment, production, profitability and the needs of major commercial and government customers.
Their careers show that wealth creation involves more than identifying opportunities. It also depends on execution, timing, risk management and the ability to respond when expectations change.
What Can Investors Learn from Their Financial Journeys?
1. Understand the Difference Between Income and Wealth
A high annual salary does not automatically make someone a billionaire. Net worth measures the overall value of assets after liabilities, while income measures money earned over a period.
Investors should distinguish between salary, bonuses, investment gains, unrealised share appreciation and the actual proceeds from selling assets.
2. Recognise the Risks of Concentrated Investments
Son’s career demonstrates how concentrated investments can create enormous opportunities while exposing investors to volatility. A business may have promising technology but still struggle with competition, excessive costs or financing requirements.
Diversification and careful valuation remain important considerations when building a long-term portfolio.
3. Consider the Benefits of Long-Term Thinking
Both executives worked with businesses requiring sustained investment. Technology development, industrial engineering and corporate restructuring rarely produce all their benefits immediately.
Long-term planning can support growth, provided that financial commitments remain realistic and businesses adapt to changing market conditions.
4. Evaluate Business Performance Rather Than Publicity
An executive’s reputation does not necessarily reflect the financial performance of every company associated with them. Investors should consider earnings, debt, cash flow, asset values and business risks rather than relying exclusively on headlines or ambitious forecasts.
