US LNG Exports Projected to Double, Driving $1 Trillion in New Infrastructure Investment

One trillion dollars. That is the scale of capital expected to flow into the United States liquefied natural gas (LNG) supply chain through 2040, according to a comprehensive new analysis by S&P Global Energy. The figure underscores a massive industrial mobilization, driven by surging global demand and a favorable domestic regulatory environment, that is rapidly reshaping the American energy landscape.[1]

The study projects that U.S. feedgas demand for LNG exports will double to 36 billion cubic feet per day within the next five years. This 25 percent upward revision from previous base-case projections is poised to elevate LNG to the second-largest net export industry in the United States, trailing only civilian aircraft and aerospace parts.[1][3]

This expansion represents a rapid maturation for a sector that only began exporting from the lower 48 states a decade ago. Today, it operates as a $44 billion annual industry that has already positioned the United States as the world's leading LNG supplier. The U.S. Energy Information Administration notes that domestic production continues to scale alongside export capacity, with five major new LNG export projects expected to start operations and ramp up production by the end of 2027.[1][4][6]

The catalyst for this accelerated growth trajectory traces back to the lifting of the U.S. LNG permitting pause in January 2025. Since that regulatory bottleneck was cleared, seven new export projects have reached final investment decisions, with several more anticipated to cross that threshold in the coming months.[1][3]

For the broader economy, the downstream consequences of this infrastructure buildout are substantial. The S&P Global report estimates that the LNG export boom will contribute $1.4 trillion to the U.S. gross domestic product and support 555,000 jobs annually through 2040. Furthermore, future LNG export activity is expected to generate more than $2.9 trillion in total revenues for U.S. businesses and $206 billion in federal and state tax revenues.[1][5]

Notably, the economic benefits are not confined to traditional energy-producing regions like the Gulf Coast or the Permian Basin. The analysis indicates that 42 percent of the supported jobs and 33 percent of the GDP contributions will occur in non-gas-producing areas. This geographic distribution reflects a vast national supply chain requiring steel, specialized engineering, manufacturing, and automation systems to construct and maintain the coastal export terminals.[1][6]

A central tension in the debate over LNG exports has historically been the potential impact on domestic energy affordability. Critics have often argued that sending more gas abroad could squeeze domestic supply and raise prices for American consumers. However, the study projects that even as export volumes double, average U.S. household natural gas costs will increase by a negligible 1.6 percent between 2026 and 2031.[1][3]

This price stability is largely attributed to the sheer abundance of domestic shale gas resources and parallel investments in extraction and transport efficiency. Benchmark Henry Hub natural gas prices have remained well below the levels common before the export era, demonstrating that domestic production can scale to meet both internal and international demand simultaneously.[6]

On a global scale, the United States is expected to capture a one-third share of the international LNG market by the end of the decade. This market dominance provides a critical alternative to Russian gas for European and Asian allies, fundamentally altering global energy geopolitics and enhancing the energy security of U.S. trading partners.[1][3]

The realization of these projections, however, hinges on the continuous buildout of pipeline infrastructure. Industry analysts emphasize that while the resource base is secure, expanding pipeline capacity—particularly into constrained regions like the Northeast—remains the primary hurdle. Ensuring that pipelines can be permitted and built efficiently will be critical to maximizing both export potential and domestic price stability over the next decade.[3][6]
