In the Ultimate Marvel universe, the X-Mansion does not differ much. However, it is not entirely funded by inheritance. Though the school originally was funded from Magneto's inheritance, allowing them to neither accept nor seek out donations. Its policies have since changed after Magneto's departure and Xavier's subsequent control over the facility. Later, the students question and ridicule the unlikeliness of the facility simply being funded by inheritance. It is then revealed that numerous donors fund Xavier's projects and remain anonymous due to heavy anti-mutant sentiments present in public opinion. One of the biggest donors was the Hellfire Club, who were revealed to have an ulterior motive for doing so. In Xavier's conversation with Lilandra Neramani, it's discovered that S.H.I.E.L.D. were former financiers before their falling out with Xavier; it is unknown what their intentions were. The Church of the Shi'ar have become major investors.
