-
FCG captures upstream producers up 19% year to date while MLPX’s toll-road pipeline fees have delivered 25% YTD and 173% over five years.
-
AMLP pays a 7% yield with quarterly distributions climbing to $1.03, offering concentrated income exposure to AI-driven natural gas pipeline volume growth.

Gas-fired plants can be sited next to data centers in two years, making natural gas the fastest dispatchable answer to AI’s surging power demand.
Data center construction across the United States is running headfirst into a power supply problem, and natural gas is emerging as the fastest available answer. Hyperscalers building AI training clusters need firm, dispatchable megawatts, and the U.S. Department of Energy projects data centers will account for up to 12% of U.S. electrical demand by 2028. That has drawn attention to three exchange-traded funds that map the natural gas supply chain from wellhead to power plant: First Trust Natural Gas ETF (NYSEARCA:FCG) on the upstream side, Global X MLP & Energy Infrastructure ETF (NYSEARCA:MLPX) covering hybrid midstream, and Alerian MLP ETF (NYSEARCA:AMLP) for pure master limited partnership exposure.
Each fund captures a different segment of the same trade. FCG owns the producers extracting gas, while MLPX and AMLP own the pipelines and processing plants that move it. Henry Hub spot prices are sitting in the $2.73 to $3.34 range in July, well below the $30.72 spike hit on January 23, 2026 during winter storms, which frames the current entry point for anyone playing this theme.

Why Gas Is Winning the Data Center Power Race
Gas-fired combined-cycle plants can be sited in roughly two years next to a data center campus, offering the around-the-clock reliability AI workloads require on a faster build timeline than new nuclear capacity, which takes a decade to permit and construct. The EIA’s May outlook forecasts the Henry Hub price to average about $3.50/MMBtu in 2026 and $3.18/MMBtu in 2027, and projects power sector gas consumption to climb from 35.2 Bcf/d in 2025 to between 38.1 and 50.4 Bcf/d by 2050. LNG export capacity is also expanding, with U.S. terminals adding roughly 0.9 Bcf/d of export capacity in April.
FCG: The Upstream Producer Trade
U.S. natural gas exploration and production companies are what FCG holds, giving it the most direct commodity price leverage of the three funds. When gas prices rise, the earnings sensitivity of E&P names tends to be greater than that of fee-based midstream operators. According to the fund’s disclosures, FCG manages $648.60 million in assets with an expense ratio of 0.99%, and its top holdings include Western Midstream Partners at 4.89%, Hess Midstream at 4.72%, and ConocoPhillips at 4.28%.
Performance has closely tracked the AI power narrative. FCG is up 19% year-to-date, trades around $28, and has returned 122% over five years. The tradeoff is straightforward: FCG rises and falls with the gas curve. If AI demand pulls prices toward the EIA’s late-decade forecast levels, upstream operators capture that lift. If new supply from the Permian and Haynesville outpaces demand, producers absorb the pressure first.
MLPX: Midstream With Cleaner Tax Plumbing
A different route is what MLPX takes. The fund holds a blend of midstream C-corporations and MLPs, deliberately capping partnership exposure at below 25% to avoid the corporate-tax drag that pure MLP funds carry. Investors receive a 1099 instead of a K-1, which matters for anyone holding the fund inside a retirement account or trying to avoid unrelated business taxable income complications.
The portfolio leans heavily toward large-cap pipeline operators. As of the February NPORT filing, top positions included Williams Companies at 9.39%, TC Energy at 8.86%, Enbridge at 8.25%, Kinder Morgan at 8.24%, and ONEOK at 6.45%. LNG exposure comes through Cheniere Energy at 6.44% plus smaller positions in Venture Global and NextDecade. Total net assets stood at $3.23 billion.
The economics here are toll-road revenue. Pipelines earn fees on volume moved, largely insulated from where gas prices settle. That has translated into strong 2026 numbers, with MLPX up 25% year-to-date and 173% over five years. Recent quarterly distributions climbed from $0.74 in February to $0.757 in May, extending a multi-year growth trend.
AMLP: Pure MLP Exposure With a High Distribution
The income-focused option is AMLP. The fund holds only master limited partnerships and tracks the Alerian MLP Infrastructure Index, giving concentrated exposure to the pipeline economy. Because the fund itself is structured as a C-corp, investors receive a 1099 rather than a K-1, sidestepping the tax-filing headache that direct MLP ownership creates.
Portfolio concentration is meaningful at the top of the book. The top six holdings account for roughly 72% of net assets, led by MPLX at 12.76%, Sunoco at 12.26%, Western Midstream at 12.24%, Enterprise Products at 12.23%, Plains All American at 11.98%, and Energy Transfer at 11.39%. LNG shows up through Cheniere Energy Partners at 4.44%, and gas compression through USA Compression Partners at 3.91%.
Income is the headline for this fund. AMLP carries a 7.34% dividend yield, with the trailing twelve-month distribution reaching $4.02 per share and the most recent quarterly payment of $1.03 in May 2026, up from $0.97 in the same quarter of 2025. Shares are up 21% year to date. Expense structure is the caveat. The fund’s fact sheet cites an expense ratio of 1.01%, higher than most peers, and it carries deferred tax liabilities that can reduce NAV growth relative to the underlying index during strong bull markets.
Matching the Fund to the Investor
The three funds solve different problems. FCG suits investors who believe AI-driven demand will push Henry Hub prices meaningfully higher and who want the operating leverage of upstream producers. It carries the most commodity price risk and the least income.
The middle ground belongs to MLPX. Large-cap midstream operators earn fees on gas throughput regardless of where prices settle, and the C-corp-heavy structure delivers 1099 reporting without a distribution yield cap. It reads as the diversified pick-and-shovel play on the theme, and it has produced the strongest 2026 total return of the three.
Income is the focus of AMLP. The 7% yield range and rising quarterly distributions reflect the cash flow midstream partnerships generate from moving gas, oil, and NGLs. Investors comfortable with concentration in a handful of partnerships and a higher expense ratio get direct exposure to the volume growth thesis without needing to file K-1s. The commodity call is covered by FCG, balanced infrastructure exposure by MLPX, and the payout by AMLP.
