Three of the world's largest asset managers have joined forces to bring institutional-style public-private portfolios to individual investors for the first time.
Wellington Management, Vanguard, and Blackstone on Wednesday launched two interval funds designed to give eligible investors simplified access to professionally managed portfolios that combine public and private markets, marking the first products from a strategic alliance announced last year. The WVB All Markets Fund will allocate 40 percent to 60 percent of assets to public equities managed by Wellington, 15 percent to 30 percent to Vanguard's active fixed-income and index strategies, and 25 percent to 40 percent to Blackstone's perpetual private markets platform. The WVB Blackstone All Privates Fund offers a single allocation spanning Blackstone's private equity, infrastructure, real estate, and credit strategies.
"The launch of the WVB All Markets and WVB Blackstone All Privates Funds reflects the strength of our strategic alliance with Vanguard and Blackstone," said Jean M. Hynes, chief executive officer and managing partner at Wellington Management, which will serve as portfolio manager for both funds. "By combining our deep active management and asset allocation capabilities with Vanguard's scale and expertise in fixed income and indexing and Blackstone's leadership in private markets, we are delivering thoughtfully constructed solutions designed to meet investors' evolving needs."
The funds will be available initially to clients of Merrill and Bank of America Private Bank, two of the industry's largest wealth management platforms. Wellington oversees more than $1.35 trillion in assets as of April 30, while Blackstone manages over $1.3 trillion as the world's largest alternative asset manager. Vanguard, the largest ETF issuer with a 50-year track record, reported that 77 percent of its funds outperformed the average return of their peer group over the 10-year period ending June 30, according to LSEG Lipper data. The WVB All Markets Fund will trade under tickers WVBIX, WVBAX, and WVBMX.
The partnership addresses a structural shift in wealth management as advisors seek to replicate the endowment-style allocation models that have long given institutions an edge over retail investors. Private markets have historically delivered premium returns and lower volatility compared with public equities, but access for individual investors has been limited by high minimums, lock-up periods, and complex fund structures. The interval fund vehicle — which offers quarterly liquidity through tender offers rather than daily redemptions — has emerged as the preferred structure for bridging that gap, following similar launches by Capital Group and KKR in 2025.
A Growing Wave of Public-Private Partnerships
The Wellington-Vanguard-Blackstone alliance is the highest-profile entry in a wave of joint ventures between traditional and alternative asset managers seeking to democratize private markets access. Capital Group and KKR launched two interval funds focused on fixed-income investments in 2025, while State Street Investment Management acquired a strategic minority stake in Coller Capital late last year to broaden private markets access for clients. Morningstar's Wealth division in June announced plans to work with Apollo, Franklin Templeton, and J.P. Morgan Asset Management on a suite of public-private model portfolios.
Kimberly Flynn, president at XA Investments, which tracks interval funds and tender offer funds, said the launch is expected to accelerate the trend. "The WVB interval fund series represents three powerhouse brands and is designed to open up private markets investing for investors who have little to no alts investment exposure," Flynn said. "A number of public/private market asset blends are in the SEC registration process now and should launch in the next six to nine months."
The funds carry important structural caveats. There is no expected secondary trading market for shares, and liquidity will be provided only through quarterly tender or repurchase offers at net asset value, with no guarantee that repurchases will occur or that investors can sell all desired shares. The underlying private market vehicles managed by Blackstone affiliates are themselves illiquid, with redemption limits and no regular secondary market.
Wellington, Vanguard, and Blackstone said they are actively exploring additional product structures to support retirement savers, financial advisors, and individual investors, signaling that the three firms view the interval fund format as a starting point rather than a final destination. The alliance also anticipates broader participation from the registered investment advisor community and will explore additional distribution channels over time.
