Jonathan D. Gray (born February 4, 1970) is an American billionaire entrepreneur who holds the roles of president and chief operating officer at the New York-based asset management company, Blackstone Group. Additionally, he serves as chairman of Hilton Worldwide.

Early life and education

Gray was raised in Highland Park, Illinois within a Jewish household. His father, Allen Gray, operated a modest auto parts manufacturing business called Blackstone Manufacturing, while his mother, Susan, later remarried James Florsheim and managed a catering enterprise. His parents separated during his childhood. Gray earned dual degrees in 1992 from the University of Pennsylvania: a Bachelor of Arts in English from the School of Arts & Sciences and a Bachelor of Science from the Wharton School, graduating magna cum laude. He was also inducted into Phi Beta Kappa.

Career

Beginning his career at Blackstone in 1992, Gray initially worked within the mergers and acquisitions and private equity divisions before transitioning in 1993 to the firm’s newly established real estate private equity group. He advanced to co-lead this division in 2005 and was appointed global head in 2011, overseeing a broad range of properties including hotels, offices, retail spaces, industrial facilities, and residential developments throughout the United States, Europe, and Asia.

Gray orchestrated Blackstone’s leveraged acquisition of Hilton Hotels, recognized as the most lucrative private equity real estate transaction ever completed, yielding $14 billion for investors. He continues to chair Hilton Worldwide’s Board following its public offering in December 2013.

Honors

In 2009, Gray was featured on Fortune’s "40 under 40" list. By 2016, he had attained the top position on Commercial Observer’s "Power 100," highlighting the most influential individuals in New York City real estate, and was also named to Vanity Fair's "New Establishment" roster.

Residential homes

In 2013, Gray played a key role in launching Invitation Homes through Blackstone to acquire foreclosed single-family houses for conversion into rental properties. The Wall Street Journal characterized this initiative as the “largest home buying spree in history,” with expenditures reaching $10 billion within its initial four years. This venture later attracted criticism for its operational model, drawing public attention including remarks from US Senator Elizabeth Warren, who condemned Blackstone for capitalizing on the aftermath of the 2008 housing crisis.

Blackstone president

Gray assumed the position of president and chief operating officer at Blackstone in February 2018, succeeding Hamilton "Tony" James in overseeing daily operations.

In this capacity, he emphasized a thematic investment approach focused on sectors poised to benefit from major macroeconomic trends such as e-commerce expansion, advancements in life sciences, AI-driven demand for data center infrastructure, energy transition initiatives, and growth in private credit markets. Furthermore, he expanded Blackstone’s investor base beyond traditional large institutional clients to include insurance companies and high-net-worth individuals.

Under Gray’s guidance, Blackstone became the first alternative asset management firm to surpass $1 trillion in assets under management and secured a place on the S&P 500 index by 2023.

Politics

During the formation of the Donald Trump administration in 2016, Gray was considered a candidate for Treasury Secretary. However, due to his affiliation with the Democratic Party, Blackstone chairman Stephen A. Schwarzman—a Trump supporter—rejected this possibility. Consequently, Gray withdrew his candidacy and Steven Mnuchin was nominated and confirmed for the role.

Gray has been an active donor to Democratic causes, supporting Hillary Clinton’s 2016 presidential campaign as well as various Democratic candidates in 2020. In 2023, he co-hosted a fundraising event for the Joe Biden 2024 presidential campaign.

Hong Kong

Gray was scheduled to speak at the November 2022 Global Financial Leaders' Investment Summit, but faced criticism from the Hong Kong Democracy Council, which argued that his participation lent legitimacy to efforts by Hong Kong authorities to obscure concerns about diminishing freedoms under the national security law. An editorial in The Wall Street Journal titled "Wall Street and Hong Kong's Strongman" mentioned Gray among executives whose alignment with Hong Kong’s leadership could harm their personal reputations as well as those of their organizations. After contracting COVID-19 himself, Gray delegated CFO Michael Chae to attend the summit on his behalf.

Philanthropy

Established in 2014, The Gray Foundation concentrates its efforts on combating inherited BRCA gene mutations and enhancing educational opportunities and healthcare access for economically disadvantaged youth in New York City.

By 2025, Jonathan Gray had contributed $245 million through philanthropic endeavors. In 2018 alone, he donated $23 million, ranking him #49 among Forbes' America's Top 50 Givers. On May 7, 2025, he announced a $125 million gift to Tel Aviv University’s Faculty of Medicine; this faculty will be renamed as the Jon and Mindy Gray Faculty of Medicine.

In February 2023, Jonathan and Mindy Gray were recognized among The Chronicle of Philanthropy's list of the top 50 donors for 2022.

Cancer research

The Grays have provided over $150 million toward research focused on BRCA-related cancers. In May 2012, they founded the Basser Research Center at the University of Pennsylvania—named after Mindy Gray’s sister Faith Basser who passed away from ovarian cancer at age 44—donating $25 million to establish it. The center is dedicated to prevention strategies, treatment development, and research into hereditary cancers linked to BRCA mutations. Their initial gift also created the Basser Global Prize to honor groundbreaking cancer research worldwide. In January 2014, they added $5 million specifically allocated for external research grants. Their philanthropy was featured in Town & Country magazine’s "Top Philanthropists of 2016."

In May 2017, they pledged an additional $21 million toward expanding the Basser Center’s work at Penn University—bringing their total commitment there to $55 million—and by July 2019 contributed another $25 million focused on genetic mutations associated with breast and ovarian cancers.

In October 2022, they donated $55 million to establish the Basser Cancer Interception Institute within the Basser Center for BRCA research. This institute aims to pioneer novel approaches that detect and treat BRCA-related cancers early enough to avoid invasive treatments such as surgery or chemotherapy. This latest contribution raised their total donations to Penn beyond $125 million.

Other philanthropy

In November 2016, The New York Times reported that the Grays gave $10 million toward a pilot initiative creating college savings accounts for thousands of New York City public school kindergartners. Jonathan Gray serves on boards including The Trinity School and Harlem Village Academies, a network of charter schools based in New York City; he contributed $10 million toward purchasing property for Harlem Village Academies’ second elementary school located in northern Manhattan. In 2019, he donated $10 million supporting first-generation low-income students attending the University of Pennsylvania. In 2021, The Gray Foundation provided $15 million to open college savings accounts seeded with $100 each for every child enrolled in New York City public kindergarten programs. In May 2025, The Gray Foundation committed $125 million to Tel Aviv University’s Faculty of Medical and Health Sciences—which will be renamed accordingly as The Gray Faculty of Medical and Health Sciences.

Personal life

Gray wed Mindy Basser in 1995 at Temple Beth Zion Israel in Philadelphia, with Rabbi Ira F. Stone presiding over the ceremony. The couple resides in Manhattan alongside their four daughters. As of August 2013, Bloomberg assessed his net worth to be slightly above $1 billion, factoring in his ownership of 40.6 million Blackstone shares valued at approximately $913 million, combined with more than $120 million earned through bonuses and salary.
