US-BASED GLOBAL INVESTMENT bank William Blair has entered into a definitive agreement to acquire Inner Circle Sports, a leading boutique investment bank focused on the global sports, media, and entertainment ecosystem.
Financial terms were not disclosed. The transaction, subject to regulatory approval, is expected to close towards the end of the second quarter and expands William Blair’s investment banking platform. Inner Circle Sports will continue to operate with its same name for a period of time post-acquisition.
Founded in 2002, Inner Circle Sports is an advisory across the sports, media, and entertainment space including team owners, leagues, investors, sports operating companies, municipalities, universities, and media/entertainment companies.
Inner Circle Sports advises clients across the full lifecycle of sports, media, and entertainment investments, including buy-side and sell-side M&A, limited partner transactions, capital raising, valuations, as well as debt financing. Notable among these is Fenway Sports Group’s roughly $480 million (£300 million) takeover of Liverpool in 2010. Four years later, the group advised Wes Edens and Marc Lasry on their $550m purchase of the Milwaukee Bucks, the highest price ever paid for an NBA team until Steve Ballmer bought the Clippers a few months later for $2 billion.
“Inner Circle Sports has built an outstanding franchise anchored by deep sector expertise, trusted relationships, and a strong entrepreneurial culture,” William Blair CEO Brent Gledhill said. “Their approach aligns closely with William Blair’s client‑first philosophy and independent partnership model. As our investment banking activity continues to accelerate, we look forward to expanding opportunities with Inner Circle Sports across our exceptional financial services platform.”
“Expanding our capabilities in sports, media, and entertainment is a key strategic priority for William Blair,” said Matt Zimmer, global head of investment banking. “The sector is experiencing strong secular tailwinds, spanning professional sports as well as youth and collegiate athletics, alongside meaningful opportunities across the broader sports, media, and entertainment ecosystem. Inner Circle Sports further enhances our ability to serve clients and deliver value across these markets, including our private equity clients with exposure to the asset class.”
“When we founded Inner Circle Sports, I could not have imagined how much the industry would evolve,” said Rob Tilliss, co-founder of Inner Circle Sports. “Partnering with William Blair is a natural fit, given our shared values and their ability to further expand our platform and resources. This combination will provide our clients with even greater opportunities going forward, and we are thrilled to be joining Brent, Matt, and their team.”
“Joining William Blair represents a compelling next chapter for Inner Circle Sports,” added Steve Horowitz, co-founder of Inner Circle Sports. “Since our founding, we have been one of the most active advisors on control transactions in the team sports industry across the U.S. and Europe. We have had the privilege of supporting exceptional clients during some of their most important and visible decisions.”
“From our early efforts with Liverpool FC and the Philadelphia 76ers to today, we take great pride in the breadth and impact of our work across the global sports, media, and entertainment sector,” Horowitz said. “Our success has been driven by the talent, integrity, and commitment of the people at Inner Circle Sports.”
