New York City's pension systems yesterday announced a $5 billion sale of private equity stakes, with Blackstone as the lead buyer.

Why it matters: This appears to be the largest PE secondaries deal ever, in terms of dollar value, and highlights how large limited partners are seeking to streamline their manager rosters.

• It's also NYC's first-ever secondaries sale, having abandoned two prior processes — one due to COVID and one due to pricing.

By the numbers: NYC's five pensions sold positions in over 125 funds managed by 74 different firms.

• That means it's now got active relationships with only around 45 different managers, and plenty of allocation headroom.
• Blackstone acquired over 95% of the portfolio.

Behind the scenes: Steve Meier, NYC's chief investment officer and deputy comptroller for asset management, tells me that the sale process began more than a year ago and arguably has its genesis in private equity's "Golden Age."

• "A number of the holdings we sold dated back to 2007 and 2008, right before the financial crisis," he explains. "New York City had hired a consultant in 2007 that brought in 50 deals in 52 weeks. Obviously that wasn't great."
• NYC picked the assets it wanted to sell, intentionally including a few strong performers as "sweeteners," rather than asking buyers to cherry-pick from a vast universe (which is sort of what Yale is currently doing).
• He declined to discuss pricing, except to say that NYC went to market with a $5 billion price tag.

Zoom in: Meier acknowledges the lack of recent private equity distributions, but says the sale was about "strategic realignment" instead of generating liquidity.

• In short, the glut of managers added a ton of work and expense — extra legal, reporting, etc. — whereas NYC now can do more co-investing and fund investing with a smaller number of partners.
• It's a refrain that lots of large LPs have been spouting, and has contributed to the recent PE secondaries boom.
• Meier also hopes that the sale will allow each of NYC's underlying pension systems to do more customization — although he cautions that there would be additional staffing needs that haven't yet been approved.

The bottom line: Private equity fundraising already is a slog, particularly for emerging managers, and the culling trend is likely to make it even more challenging.

Neuralink, the brain-implant startup founded by Elon Musk, raised $600 million at a $9 billion pre-money valuation, per Semafor.

Why it's the BFD: The company seeks to help people with quadriplegia communicate. It's a noble goal, no matter what one might think of Musk.

• It's also yet another Elon unicorn that's sparked VC-backed copycats, which means that every dollar counts.

Zoom in: Semafor didn't report on any new investors. When I asked a source about who led the $600 million round, the response was that Neuralink usually sets its terms.

• Some reports put Neuralink's prior valuation at $3.5 billion and others at $5 billion. Either way, this is a major step-up.

The bottom line: "Neuralink last year received the 'breakthrough device' clearance from the U.S. FDA. Three people have so far received implants made by Neuralink. Earlier this month, a nonverbal patient posted a video about how he uses a Neuralink implant to edit and narrate YouTube videos with just his brain signals." — Ivan Mehta, TechCrunch
