Key Takeaways
  • • Blackstone is taking over Equity Office Properties Trust, the US real estate investment trust founded by Sam Zell, in a deal the headline describes as the world's biggest private equity deal ever.
  • • The source article does not disclose a transaction value, financing structure, or closing timeline.
  • • The report, dated 23 January 2013, cites warnings that the collapse of large buyouts across all sectors of private equity is "inevitable."
  • • The article is from January 2013, so the transaction should be read as historical context rather than a current development.
Summary
According to a 23 January 2013 report by Robin Marriott on pei-privaterealestate.com, US buyout firm Blackstone is taking over Equity Office Properties Trust, a US real estate investment trust associated with Sam Zell. The article's headline characterizes the transaction as the world's biggest private equity deal ever.

The report places the acquisition alongside warnings that the collapse of large buyouts across all sectors of private equity is "inevitable." The source does not specify the transaction value, financing terms, or closing timeline, so those details cannot be confirmed from this article.

The story is categorized under deals, fundraising, people, and regional coverage of Europe and North America. Because it is dated January 2013, its reference to the Blackstone transaction should be treated as historical context and not as a current development as of July 2026.
