Bill Ackman to Demolish SNL Studio for Major Brain Research Institute on Upper West Side

American hedge fund manager Bill Ackman, a prominent figure known for his activist investing strategies through Pershing Square Capital Management, has unveiled ambitious plans to redevelop a significant parcel of real estate on Manhattan's Upper West Side. The centerpiece of this redevelopment will be the Ackman Oxman Institute, a cutting-edge facility dedicated to brain research and medical rehabilitation. Ackman revealed these intentions during a discussion with Mansueto Ventures CEO Stephanie Mehta at the Fast Company Innovation Festival. The impetus for this substantial investment in the life sciences sector appears to be a deeply personal one: his 26-year-old daughter suffered a brain hemorrhage in February 2026, a medical emergency that has clearly galvanized his commitment to advancing neurological care and research.

Ackman first publicly shared details of his real estate acquisition strategy via an X (formerly Twitter) post on August 19. He disclosed that the Pershing Square Foundation, a philanthropic arm of his broader financial endeavors, had successfully acquired a nearly vacant 400,000-square-foot biotech facility. This property is strategically located on West End Avenue, between 65th and 66th Streets, an area already recognized for its burgeoning life sciences presence. Complementing this acquisition, Ackman also detailed plans to secure an adjacent 120,000-square-foot space situated on 66th Street. This adjoining property is notably the location of a studio utilized by the iconic television program *Saturday Night Live* (SNL), a show produced by Broadway Video and broadcast on NBC.

While Ackman initially indicated that the SNL building was scheduled to cease operations in December, he maintained a degree of suspense regarding the specific future of the structure until a subsequent panel discussion on September 15. During his appearance at the Fast Company Innovation Festival, Ackman offered a candid, albeit somewhat playful, glimpse into his intentions for the SNL site, stating, “Don’t tell Saturday Night Live yet, but we’re going to tear that down. They’ll probably do an episode about me when we tear down the building.” This remark underscores the high-profile nature of the project and the potential for public interest and commentary.

Reports suggest that Ackman's combined investment for the biotech facility and the adjacent properties amounted to nearly $260 million. The overarching vision extends beyond a single institute, aiming to cultivate a comprehensive medical research campus. Ackman articulated the immense potential of the site, noting, "We have potentially 2.5 million square feet of buildable area where we’re going to bring a ton of jobs." This ambitious undertaking signifies a major commitment to fostering innovation, creating employment opportunities, and advancing critical medical research within the heart of New York City, positioning the Ackman Oxman Institute as a potentially transformative force in brain health.
