A new pool of capital is increasingly finding its way into America’s LNG and pipeline infrastructure, changing how some of the country’s major energy projects are financed. Alternative asset managers including Apollo Global Management, Blackstone and KKR are deploying money from their insurance businesses into LNG terminals, pipelines and other midstream assets, providing developers with long-term funding as energy infrastructure requires billions of dollars in new investment.
The scale of the shift is already becoming visible. Alternative investors participated in $20.35 billion worth of LNG and midstream transactions in 2026, according to Infralogic — more than twice the value recorded across the whole of 2024. The influx comes as the US expands LNG export capacity while pipeline operators invest in the infrastructure needed to move natural gas to growing markets.
The financing model is particularly attractive to insurance-linked capital because LNG terminals and pipelines can generate relatively predictable, long-term revenues. LNG projects can secure contracts lasting up to 20 years, while fixed-price construction agreements can provide greater certainty over development costs. Together, these characteristics make energy infrastructure increasingly suited to investors looking for long-duration assets.
LNG Finds a New Pool of Long-Term Capital
The trend is already visible across several major US projects. Sempra Infrastructure’s second phase of Port Arthur LNG attracted a $7 billion investment, while Woodside Energy’s Louisiana LNG project received a $5.7 billion commitment from Stonepeak, which acquired a 40% stake. NextDecade’s Rio Grande LNG Train 4 also brought together BlackRock’s Global Infrastructure Partners, GIC, Mubadala and TotalEnergies as equity investors.
This broadens the financing options available to developers beyond conventional project finance, bank lending and corporate equity. It also comes as expectations for US LNG demand strengthen, supported by European and Asian buyers, geopolitical concerns around energy security and rising electricity consumption from data centres and artificial intelligence infrastructure.
The result is a changing investment landscape in which LNG projects are increasingly being viewed not simply as commodity plays, but as long-term infrastructure assets with contracted revenue streams.
Pipelines Become Part of the Same Investment Story
The financing trend is extending into the pipelines that connect gas production to LNG terminals, power plants and industrial consumers. Blackstone Credit & Insurance invested $3.5 billion in 2024 for a 49% stake in a joint venture holding EQT’s midstream assets, while Williams and ONEOK have also used alternative financing structures to support infrastructure expansion.
ONEOK’s $9 billion deal with Apollo, announced in August, is particularly notable because it was structured as a minority investment directly in the company rather than being tied to a single project. In Canada, KKR and Apollo have also agreed to invest about C$2.7 billion in Enbridge’s Westcoast Pipeline expansion projects, showing that the model is spreading beyond the US.
The significance goes beyond individual transactions. Energy projects can remain stuck between planning and construction when developers cannot assemble sufficient capital on acceptable terms. The growing involvement of insurers and alternative asset managers creates another route through that bottleneck.
For emerging gas markets such as Africa, the development is worth watching. Countries with significant gas reserves but large infrastructure financing gaps may increasingly need the same combination of long-term institutional capital, reliable offtake agreements and bankable infrastructure structures to turn resources into pipelines, processing facilities and LNG capacity.
America’s LNG expansion therefore points to a broader reality for the energy industry: the next generation of gas infrastructure may depend as much on finding the right capital structure as on finding the gas itself.
