The San Francisco Giants ownership group is likely adding another voice to the board.

Thrive Eternal is poised to purchase a minority stake in the team, founder Joshua Kushner announced on Friday. Thrive Eternal is based in New York and calls itself a permanent capital holding company.

Kushner, brother to President Donald Trump’s son-in-law Jared Kushner, announced the partnership with the Giants as the group’s first, adding in a statement on X that the firm was expanding to invest in “assets with qualities that cannot be replicated by technology.”

“Our first partnership is expected to be with the San Francisco Giants,” Kushner wrote on X. “An institution built on more than a century of shared identity and community, and among the most iconic sports franchises in America. We have reached an agreement, subject to league approval, to acquire an ownership stake. We feel privileged by the opportunity to be long-term partners to the Giants.”

The Giants confirmed the partnership in a statement: “We have reached an agreement for Thrive Eternal to join our investor group, subject to MLB approval. We are thrilled with the prospect of Eternal becoming a long-term partner for the Giants.”

The Giants ownership group has been steadily taking on private equity groups since last year. Last March, the organization sold 10% of the team to Sixth Street, a San Francisco-based private equity firm that also owns the local National Women’s Sports Soccer team Bay FC.

“This is our first significant investment in three decades,” Giants president and CEO Larry Baer said in a statement when that deal was made public.

Arctos Sports Partners, a Dallas-based firm, owns about 2% of the Giants and owns a stake in the Golden State Warriors.

The terms of the Giants’ partnership with Thrive Eternal are yet to be announced pending MLB approving the deal, the Giants said. 

Briefly: A pair of former Giants were designated for assignment on Friday. The Toronto Blue Jays DFA’d former Giants infielder Tyler Fitzgerald to make room on their roster for catcher Willie MacIver. Additionally, the Milwaukee Brewers DFA’d outfielder Luis Matos in a series of roster moves. The Giants earlier this season DFA’d and traded Fitzgerald and Matos for cash considerations. Matos was a top prospect in the organization who couldn’t find his footing on the big league team. Fitzgerald had a breakout month-plus in 2024 but struggled in 2025 before San Francisco cut him loose early in the 2026 season.
