@PurpleTitan No neither Oxford nor Cambridge have £2 billion endowments those are simply the central university funds as I’ve stated each college has their own separate endowment some richer than others. I get my figures from the accounts and financial statements of the universities and not news articles.
Cambridge currently are planning to start a £2 billion fundraising campaign after their successful £1.2 billion campaign that started in 2009. Cambridge has hired leaders of university funding campaigns in the us for instance Alison Traub who led UVA’s $3 billion fund raising campaign.
Oxford university has raised £2 billion and wants to extend it to £3 billion soon they aim to grow by £1 billion per year.
