Blackstone’s infrastructure success sparks surge in transition-focused funding and secondary markets

Blackstone’s infrastructure arm closed out 2025 on a notably strong note, with performance and capital-raising both powering a step-change in its open-ended strategy, according to reporting by Infrastructure Investor and company statements. The firm’s infrastructure business delivered a 23.5 percent gross return across the year, and Blackstone Infrastructure Partners (BIP) has produced an 18 percent net return since inception, figures the firm highlighted during its fourth-quarter earnings call. “One of the best years yet,” Blackstone president Jonathan Gray said on the call, pointing to the QTS data-centre platform as the single largest contributor to returns.

Fundraising momentum accompanied performance. Blackstone said it secured roughly $4.2 billion for infrastructure in the fourth quarter and $13.3 billion for the full year, surpassing 2024’s haul. Industry reporting notes BIP expanded about 40 percent year-on-year to roughly $74.5 billion–$77 billion including co-investments–as investors added to allocations to digital, energy and transport infrastructure. The firm also announced the launch of Blackstone Energy Transition Partners V; Gray said the vehicle will be “meaningfully larger” than its $5.6 billion predecessor, with a spring first close anticipated.

Blackstone’s reach into secondary markets was underscored by the final close of Strategic Partners Infrastructure IV L.P. at $5.5 billion, which the company described as the largest dedicated infrastructure secondaries fund raised to date. The vehicle is intended to capitalise on growing liquidity and restructuring opportunities in infrastructure secondaries, the firm said.

Asia-focused manager Seraya Partners has itself advanced fundraising and deployment. Infrastructure Investor reported a first close of about $650 million on Seraya’s Fund II, bringing it nearly halfway to a $1.5 billion target. Seraya confirmed its inaugural Fund II investment is a controlling stake in G&B Infratech, a South Korean developer and operator with some 200MW of operating solar and onshore wind assets under long-term 20-year contracts and exclusivity over a proprietary 1GW development pipeline. Seraya is committing $250 million of equity to the platform with the stated aim of building it to roughly 1GW of capacity; the firm’s first fund has been recognised by Preqin as a top performer in its size category and has delivered an approximate 21 percent net IRR to date, according to Seraya.

In Europe, debt-focused managers are also finding investor interest for energy-transition lending. Paris-based LBP AM European Private Markets has reached the €500 million target for its Article 9 energy transition infrastructure debt fund, which prioritises financing low-carbon and decarbonisation assets, renewables, clean transport, circular economy and energy-efficiency projects, with a particular focus on France. The manager says the vehicle has already deployed about two-thirds of its capital and attracted new institutional limited partners, including anchors such as Aegon AM and CNP Assurances.

SWEN Capital Partners, meanwhile, has closed SWIFT 3 at €440 million for its third renewable fuels vehicle. Launched in January 2025 with a €1 billion goal, the fund falls short of that target and of the previous vintage’s take, but SWEN reports a diversified investor roster including the European Investment Fund and North American pension capital. The strategy targets early-stage and greenfield investments across biomethane, e‑fuels, biofuels and complementary low-carbon infrastructure, and the vehicle has completed five investments against an aim of 15–20.

Taken together, the sector’s recent activity illustrates two parallel trends: greater institutional appetite for both primary and secondary infrastructure exposures, particularly where assets can deliver energy-transition outcomes or digital infrastructure scale; and a willingness among managers to press forward with larger or follow-on vehicles after strong track records. Blackstone’s mix of performance-driven fundraising and sizeable secondary capability, Seraya’s rapid move from a high-performing debut fund into sizeable renewables platform build-out, and the successful closes of specialist debt and fuels vehicles in Europe all signal a market still flush with capital for transition-oriented infrastructure, even as some funds fall short of ambitious targets.
