Blackstone wanted a simple thing: raise cash from an older fund and hand it back to the investors waiting for it. The tool it chose turned out to be anything but simple.
The plan was to raise about $3 billion through a deal code-named Project Eclipse for an older fund in Blackstone's secondaries business. That business buys and sells stakes in private funds.
The fund held about 700 underlying investments, and Blackstone spent months preparing the deal. The structure was a collateralized fund obligation, or CFO, which bundles private fund stakes and sells debt notes backed by them.
The cash from those notes would go to the older fund's investors. CFOs also give fixed-income investors, like insurers, a way to earn returns from private funds they normally cannot reach.
Jefferies Financial Group advised Blackstone on the deal, and a Jefferies spokesperson declined to comment. People with knowledge of the deal asked to remain anonymous because the details were not public.
CFOs are structured in layers. The safest layers collect their money first, and the riskiest layer - the equity tranche - takes the first loss if the underlying stakes lose value.
That same layer earns the biggest returns when the deal works out. The equity tranche can account for 10% to 20% of the total money raised in a CFO.

Issuers often keep up to 20% of that equity for themselves to show new investors they share the risk. Blackstone went further and signaled it would keep the entire equity tranche just to close the deal.
It still struggled to find a buyer, according to people familiar with the deal.
As of August 12, 2026, executives could still push the deal through, or they could find another route to return cash to existing investors.
Even with this deal stuck, the wider market for CFOs is picking up speed. A multiyear slump in deal-making has cut profits at asset managers and made traditional fundraising harder.
That has pushed more money toward secondary markets and toward CFOs. Secondary markets are where investors buy existing stakes in private funds from other investors.
CFOs give managers a way to keep cash moving when raising new money is tough. Evercore expects new CFO volume to more than double this year to $30 billion.
Ardian is raising a $1 billion CFO right now, and Pantheon completed its first CFO earlier this year. Pantheon backed its deal with secondaries funds, co-investment strategies, and a portfolio of seeded private equity investments.
Carlyle's AlpInvest and Dawson Partners have raised multiple CFOs tied to their secondaries or credit funds. In May, Carlyle put together an $8.5 billion structured credit package in a CFO-like structure.
Most investors will never buy a CFO. But insurers and pension funds do, and that is the money behind your insurance policy and your retirement account.
So when the biggest names in private markets struggle to sell the riskiest slice of a $3 billion deal, that says something about the market. Pickier buyers push prices around, and those prices ripple into the returns of the institutions holding the debt.
If Blackstone walks away, it is not a disaster. Executives can find other ways to get cash back to investors.
For a regular investor, the story is a window into how complex private investing has become. The machinery behind the returns is getting more complicated, and even the pros sometimes have to stop and rethink it.
The bigger these deals get, the more they depend on someone willing to take the first loss. That is the quiet risk hiding inside a booming corner of finance.
