Masayoshi Son and Greg Hayes share headlines from December 2016 but nothing more. That month, Son pledged $50 billion toward U.S. investment through SoftBank. Meanwhile, Hayes defended a Carrier plant decision that put Indiana jobs in the spotlight. Searchers often wonder whether the two leaders are relatives, partners, or former colleagues.
Public records confirm no such ties. Son built a global technology investment group from a small software distributor. Hayes climbed the corporate ladder at United Technologies before steering RTX through a landmark merger. Their stories collided in a single December news cycle. Here’s what each man actually did, why people link them, and where their careers stand in 2026.
Who Is Masayoshi Son?
Masayoshi Son is a Japanese entrepreneur, investor, and founder of SoftBank Group. He was born on August 11, 1957. Over the decades he earned a reputation for placing huge bets on technology before most people saw the payoff.
Son started the business that became SoftBank in 1981. It began as a software distributor. Then it grew. Telecommunications, internet services, investment funds, semiconductor technology, and artificial intelligence all joined the mix over time.
Think of him less as a manager and more as a talent scout with a very large checkbook. He spots a young company, decides it could shape an industry, and commits serious capital. Alibaba and Arm stand out among his best-known investments. More recently, he has tied SoftBank to OpenAI.
That approach carries risk. Big wagers can produce big wins. They can also produce costly misses, and Son’s career includes both. Artificial intelligence, advanced computing, and semiconductor infrastructure now sit near the center of SoftBank’s long-term strategy.
Here’s the key point for comparison. Son built his name as a founder and investor. He didn’t climb through an established industrial company. That difference matters when you set his story beside Greg Hayes.
Who Is Greg Hayes?
Gregory J. Hayes is an American business executive known for leading United Technologies Corporation and RTX. His career followed a classic corporate path. He moved through finance, planning, and strategy roles inside large organizations.
Hayes joined United Technologies in 1999 after its merger with Sundstrand. Several senior finance and strategy positions followed. In 2014, he became CEO. Two years later, in 2016, he added the title of chairman.
His education shaped that path. Hayes earned a bachelor’s degree in economics from Purdue University and qualified as a Certified Public Accountant. Those financial roots show up in how he ran companies. He focused on acquisitions, restructuring, and operational efficiency.
His biggest career moment came in 2020. United Technologies’ aerospace businesses combined with Raytheon Company. The new organization became Raytheon Technologies and was later renamed RTX. Hayes served as chairman and CEO of the combined business before stepping back from executive leadership.
He stepped down as executive chairman and left the RTX board in April 2025. Since then, his work has centered on corporate governance and board responsibilities. In 2026, that includes roles at Phillips 66 and Becton, Dickinson and Company.
What Connects Masayoshi Son and Greg Hayes?
The link between Masayoshi Son and Greg Hayes is historical rather than personal. Both men found themselves in prominent American business headlines during December 2016. Their companies had no shared project. The headlines simply landed in the same news cycle.
Both stories touched the same themes: investment, employment, industrial competitiveness, and the economic priorities of the incoming U.S. administration. Yet the companies and goals behind them were separate.
The December 2016 Investment and Jobs Announcements
In December 2016, Son met then-President-elect Donald Trump. He announced that SoftBank planned to invest roughly $50 billion in the United States. The announcement focused on technology businesses. It also carried expectations of supporting tens of thousands of American jobs.
Around the same time, Hayes faced a very different problem. Carrier, then owned by United Technologies, planned to move manufacturing jobs from its Indiana facility to Mexico. Trump publicly pressured United Technologies and Carrier to keep those jobs at home.
Negotiations followed. The resulting arrangement let hundreds of positions stay in Indianapolis. Carrier also planned a $16 million investment in the facility.
However, Hayes explained that part of that money would go toward automation. That detail matters. Automation can raise productivity and lower costs. It can also reduce the number of workers needed for certain tasks.
Look at the two stories side by side. Son’s announcement was about funding future technology. Hayes was dealing with factory costs, plant operations, and a politically charged jobs debate. One leader promoted new investment while the other defended an existing industrial base.
That contrast explains why people mention them together. It doesn’t mean the two men worked on anything jointly.
Are They Direct Business Partners?
No. Reliable public records don’t show that Masayoshi Son and Greg Hayes ever ran a business together. They haven’t served on the same corporate board either. No shared venture has been documented.
Their work points in different directions. Son’s world covers SoftBank, technology investments, telecommunications, semiconductors, and artificial intelligence. Hayes’s world covers United Technologies, RTX, aerospace, defense, and corporate governance.
One possible source of confusion is Rene Haas, the CEO of Arm. Haas has a real corporate connection to Son because SoftBank owns Arm. Hayes holds no comparable role within SoftBank. Mixing up similar-sounding names can create a false impression of a partnership.
So the accurate description is a historical news connection. It isn’t a documented business partnership or a family relationship.

Masayoshi Son’s Net Worth and SoftBank Ownership
Masayoshi Son ranks among the wealthiest business figures in Japan. His fortune comes mainly from his ownership interests in SoftBank and other technology investments. The reference estimate for 2026 puts his net worth at about $80 billion. Treat that as an approximation. Market conditions, company valuations, and share prices can shift it quickly.
The reason is simple. A large share of his wealth ties to stock prices. When technology shares climb, his net worth rises. When they fall, it can drop sharply.
Greg Hayes’s personal net worth hasn’t been reliably confirmed. During his executive career, he received compensation through salary, performance incentives, and equity awards. Executive pay isn’t the same as total personal wealth, so any specific figure would be a guess.
The financial backgrounds of Masayoshi Son and Greg Hayes reflect their different careers. Son’s wealth rests on entrepreneurship and investment ownership. Hayes’s earnings came from corporate leadership and executive compensation.
How Much of SoftBank Does Masayoshi Son Own?
Exact figures change over time. Son has been the largest individual shareholder of SoftBank Group for years. Reports in recent years have generally placed his stake in the high-twenties percent range. Share sales, buybacks, and financing arrangements can move that number.
Because of that, you should check SoftBank’s latest filings for a current figure. A precise percentage isn’t confirmed here. What’s well established is the broader point. Son remains tightly linked to SoftBank both as its founder and as its leading personal shareholder.

What Are Masayoshi Son and Greg Hayes Doing in 2026?
Masayoshi Son continues to guide SoftBank’s strategy. His focus includes artificial intelligence, semiconductor technology, data centers, and advanced computing. He believes increasingly capable AI systems could transform industries and have a deep effect on society. That belief drives much of SoftBank’s capital allocation.
Greg Hayes has moved away from daily executive duties. After leaving RTX, he took on corporate board and governance work. His experience with mergers, acquisitions, financial planning, and restructuring still carries weight. Companies such as Phillips 66 and Becton, Dickinson and Company benefit from that background.
The two men now sit at different stages of their careers. Son remains hands-on in running his investment group. Hayes now oversees and advises established businesses rather than managing them every day.
If you follow both names in the news, expect different kinds of headlines. Son’s will revolve around AI deals, chips, and funding. Hayes’s will revolve around boardrooms and governance.
