ADIA buys into a Saudi endowment's $1 billion sale

Abu Dhabi's two funds bought on both sidesRevelar files a continuation fund for RAYUS Radiology

The Abu Dhabi Investment Authority has bought into a portfolio of at least $1 billion that a Saudi university endowment is selling, Secondaries Investor reported overnight. Mubadala, Abu Dhabi's other fund, put about $1 billion into a vehicle Centurium built for its Luckin Coffee shares. Norway's fund, meanwhile, said it will buy property fund stakes to fill a $60 billion allocation. So the sovereigns are this month's bid, and Korea's is the offer.

Number of the day
21%
Sovereign wealth funds' share of the fund interests sold in the first half, up from 12% in 2025, in Evercore's count. Two of them are now buying.

Abu Dhabi's two funds bought on both sides

Abu Dhabi's two sovereign funds have bought in both halves of the secondary market this month. ADIA took part of a portfolio of at least $1 billion that the KAUST endowment is selling, Secondaries Investor reported early on Tuesday. The sale is still running, so the funds in it, the other buyers and the price are not known. The purchase reverses the pattern of the first half, when Evercore counted sovereign funds as 21% of the sellers and endowments as about a tenth.

Mubadala's purchase is the other half, a GP-led that never used the name. On 5 September a subsidiary of CCM Success, a new partnership, agreed to buy 241 million Luckin preferred shares from two Centurium funds. The 13D/A of 9 September names Mubadala's MIC Industrial Investments 4 as "a significant limited partner" in the new vehicle. The filing expects a bank loan secured on the shares to finance the purchase, and Centurium's own 22.1% stake does not change, because it manages the buyer as well as the sellers. Mubadala announced the investment on 10 September at "approximately US$1 billion aggregate value". So a 2018 fund sold a listed holding to a vehicle its own manager runs, with a sovereign as the new money. The filing gives the reason in a sponsor's words, because the deal will "allow Centurium Holdings to reaffirm its commitment to, and extend its investment horizon in" Luckin.

An investor selling a $1 billion portfolio this autumn therefore bids into a market with sovereigns on both sides. Korea Investment Corp hired PJT last week to sell more than $1 billion of fund interests, and ADIA raised its private equity range to 15% to 20% in 2025. That buying money sits outside the advisors' dry powder, because Evercore's estimate "excludes a growing pool of capital from non-traditional buyers, including institutional LPs, evergreen funds, insurers, sovereigns". So a seller running a full process collects those bids next to the secondaries funds', which is how 88% of the half's LP-led volume ran through an advisor.

Revelar files a continuation fund for RAYUS Radiology

Revelar Capital has started raising a continuation fund for RAYUS Radiology, the Minneapolis imaging chain it bought in March 2019. Three partnerships filed with the SEC on Monday from the firm's Third Avenue address, with Piper Sandler as placement agent, of indefinite size and with nothing raised yet. Their names describe the structure. Revelar RAYUS Continuation Fund takes the new money, and the Rollover Continuation Fund takes the investors who roll. The Continuation Fund Seller partnership is the channel through which the selling fund passes its stake. Revelar is the name Wellspring Capital Management took in October 2025, and its site puts assets under management at $4.6 billion across healthcare, business services and specialty manufacturing.

RAYUS is most probably the fourth company to leave the same fund this way. Wellspring bought Center for Diagnostic Imaging fourteen months after closing Wellspring Capital Partners VI at $1.415 billion in January 2018. It gave the company the RAYUS name in 2021 and grew it from 123 to 148 centers in the twelve months to October 2021. In March 2024 the firm moved SupplyOne, Cadence and Pentec Health out of Fund VI into a $975 million continuation fund led by Lexington and Neuberger Berman. Campbell Lutyens advised, and a month later NorthSands led a single-asset vehicle for SupplyOne alone. The filings do not name the selling fund, though, so the honest alternative is that RAYUS sits in an older Wellspring vehicle. The 2024 fund kept $125 million unfunded for add-ons. Its release said the vehicle "will provide more time and additional capital to assist each portfolio company in achieving its growth potential".
