Sixth Street backs women's football platform Bay Collective amid private capital surge

Global investment firm Sixth Street has backed Bay Collective, a multi-club women's football ownership platform, as private capital flows into women's sport at scale. The NWSL franchise's value rose from $2 million in 2021 to over $200 million in 2026, while McKinsey research found women's sports revenue grew 4.5 times faster than men's between 2022 and 2024. Bay Collective currently owns Bay FC in San Francisco and acquired a majority stake in Sunderland AFC Women in June 2026. Nielsen research found NWSL viewership up 61% in 2025, with 64% of fans identifying as male. CEO Kay Cossington MBE said the platform benefits from "the patient capital of Sixth Street" alongside expertise in sustainable deployment specifically for women's football. The platform spans marketing, commercial strategy and match-day experience across two major women's football markets.

Beam Therapeutics secures $500M credit facility with Sixth Street for sickle cell treatment launch

Beam Therapeutics has secured a $500 million senior secured credit facility with Sixth Street to support the anticipated launch of ristoglogene autogetemcel (risto-cel) for sickle cell disease. The agreement includes $100 million funded at close, up to $300 million available upon clinical, regulatory and commercial milestones, and an additional $100 million at Beam's option. The facility has a seven-year term maturing in early 2033, with an annual interest rate of approximately 10% based on SOFR. No scheduled amortization payments are required, with all principal due at maturity. Beam expects to draw at least $200 million under the facility. The financing provides non-dilutive capital to support risto-cel's commercialisation whilst allowing Beam to direct resources towards pipeline growth and developing precision genetic medicines.
