A letter that went out to investors in Blackstone’s flagship retail fund this month carried a figure the firm had never printed for the vehicle before. Class I shares of the Blackstone Private Equity Strategy Fund, the retail-oriented fund known as BXPE, returned 4.3% on a net basis in May, the strongest single month since the fund’s launch, according to people familiar with the matter.
The gain carried the fund’s return for the first five months of 2026 to 11.4%, the people said. Blackstone has attributed the performance in part to its stake in Anthropic, the artificial-intelligence company whose revenue growth has made it one of the most sought-after private assets in the technology industry. The fund also booked gains across a cluster of holdings tied to the AI build-out that were marked up in recent appraisal cycles.
BXPE deployed more than $2.5 billion in the second quarter, the firm said, including a follow-on investment in Anthropic and a new position in Stripe, the payments processor. The two names illustrate the fund’s strategy of concentrating capital in companies on either side of the AI boom: the model makers that sell intelligence and the payment networks that move the revenue it generates.
Blackstone created BXPE in late 2021 as the centerpiece of a push to sell private equity to wealthy individuals. The vehicle buys stakes in buyout deals once reserved for pension funds and endowments, reports performance monthly and permits limited redemptions each quarter. Its Class I shares are marketed through financial advisers, and Blackstone has folded the fund into a family of retail vehicles spanning real estate, credit, infrastructure and secondaries.
Anthropic, founded in 2021 by siblings Dario and Daniela Amodei, has become one of the defining private investments of this cycle. The startup, backed by Amazon and Alphabet, has raised successive rounds at rising valuations as businesses pay for its Claude models and developers build on its application programming interfaces. Blackstone has built its position through a series of direct investments, adding to it again during the second quarter, and the stake has appreciated sharply as private-market appraisals have caught up with the company’s commercial momentum.
The May number stands out against the fund’s own history. BXPE has posted steady single-digit gains in most months since its launch, and its managers have been careful to tell investors that monthly returns will vary with appraisal cycles. A 4.3% month, by that standard, is an outlier, and for Blackstone’s distribution teams it is also a useful one.
Analysts said the result shows how AI exposure has become a selling point for retail private-asset vehicles. Private-markets firms have pushed hard into wealth distribution over the past three years, signing up advisers and building client apps for investors who want a piece of buyout returns without committing to decade-long lockups. A fund that can cite a double-digit return driven by the industry’s most sought-after startup gives advisers a concrete number to repeat.
The concentration cuts both ways. Private funds value holdings with periodic appraisals rather than daily marks, and the same process that lifted May’s number could reverse if AI valuations cool. BXPE also caps quarterly redemptions, a structure that steadied Blackstone during the 2022-2023 real-estate redemption crunch but has drawn complaints from advisers who want faster exits for their clients.
Rivals are watching the numbers as closely as investors are. KKR, Apollo Global Management and Ares Management have all built retail products of their own, and each has been hunting for headline AI exposure. Blackstone’s scale in the channel remains the largest, and a fund with momentum makes it harder for competitors to pitch their own vehicles to the same advisers.
Part of BXPE’s appeal has been its price. The fund’s Class I shares carry a fee structure Blackstone defends as reasonable for a product with active management and quarterly liquidity, though critics note that retail investors pay more for the same buyout exposure than institutions do. The firm has said the extra cost buys access and reporting that individuals could not otherwise obtain, and its distribution network, the largest in the private-markets industry, has made the fund a default holding in many adviser-managed portfolios.
Investors should also weigh what the fund does not show. Monthly performance figures reflect Blackstone’s own valuations of private holdings, updated on a schedule and reviewed by third-party firms, and those marks can lag public-market moves by months. When technology stocks sold off in earlier cycles, BXPE’s appraisals took time to catch up, a lag that flattered the fund in one direction and stung in the other.
The stakes extend beyond one fund. Blackstone has told investors that wealth clients will be its largest source of new capital over the coming decade, and BXPE is the flagship of that effort. A run of strong monthly numbers makes the sales pitch easier; a reversal would test the firm’s argument that private assets deserve a permanent place in individual portfolios, not just in institutional ones.
Blackstone declined to comment beyond what it has told investors. For now, the May figure gives the firm a fresh number for its pitch to advisers and gives investors a fresh reason to watch what the appraisal cycle does next.
