While the S&P 500 has trudged to a 4.7% gain year-to-date, the dullest pocket of the energy complex has been a quiet bull. Natural-gas pipeline operators — the toll-takers that move molecules from the Permian and Marcellus to LNG docks and power plants — are up 20-30% YTD, beating the broad market by five to six times. The trade has a name nobody is using yet, but two themes are doing the work: the AI data-center power buildout and a U.S. LNG export wave that is finally landing volumes.
The scoreboard: midstream vs the index
The headline names are all running well ahead of the S&P. Williams Companies, the operator of Transco (the biggest U.S. interstate gas pipeline by throughput), leads the pack.
| Ticker | Company | YTD Return | Mkt Cap | Div Yield | P/E (TTM) |
|---|---|---|---|---|---|
| WMB | Williams Companies | +30.5% | $96.0B | 2.68% | 34.4x |
| OKE | ONEOK | +27.9% | $59.2B | 4.55% | 16.8x |

| ET | Energy Transfer | +21.7% | — | — | — |
| ENB | Enbridge | +20.8% | $126.7B | 4.86% | 27.0x |
| SPX | S&P 500 | +4.7% | — | — | — |
Five of the six biggest North American gas-leveraged pipeline names are within a percentage point or two of 52-week highs. ONEOK, for instance, is trading at $94.03 against a 52-week high of $96.07. This is not a one-stock story or a short squeeze — it is a coherent sector move.
Why now: three converging tailwinds
1. AI data centers want gas, not just kilowatts
Data-center power demand has gone from a long-tail growth story to an immediate planning constraint. The EIA’s latest Short-Term Energy Outlook (May 2026) projects total U.S. electricity consumption rises 1.3% in 2026 to roughly 4,250 billion kWh, and 3.1% in 2027 — rates the U.S. grid has not seen since the early 2000s. EIA attributes the acceleration to commercial and industrial users, with data centers explicitly called out as a top driver. A separate EIA Today in Energy piece on May 19, 2026 projects server electricity use could reach 22-33% of all commercial-sector electricity by 2050.
Critically, hyperscalers want power that is firm, dispatchable, and on a multi-decade contract horizon. Solar and storage are growing fast, but the marginal molecule for new gigawatt-scale loads in Texas, Virginia, and the Mid-Atlantic is gas. That is the asset pipeline operators already own.
2. LNG export volumes are landing — finally
The U.S. LNG export buildout has been an investment thesis for half a decade. In 2026 it is becoming a cash-flow event. EIA’s STEO forecasts U.S. LNG exports averaging 17.0 Bcf/d in 2026, rising to 18.2 Bcf/d in 2027 — up from roughly 13 Bcf/d two years ago. The ninth U.S. export terminal, Golden Pass LNG, shipped its first cargo in April 2026. Pipelines feeding those terminals (Transco, Permian Highway, Gulf Coast Express, Whistler) get paid per molecule moved.
3. A geopolitical bid on top
EIA flagged in late April that a Strait of Hormuz disruption has affected roughly 20% of global LNG trade, widening the U.S. vs international gas-price gap and pulling buyers toward Henry-Hub-linked supply. Combined with European storage rebuild demand, U.S. LNG cargoes are clearing at a premium that was not in 2025 contracting forecasts.
What the YTD gap looks like
The gap is wide enough that midstream is no longer a defensive carry trade. It is doing the work of a growth allocation while still paying dividend yields north of the 10-year Treasury.
What’s actually changed in the business
Three numbers reframe how the cash-flow profile has shifted:
- Production base: U.S. marketed gas production averaged 120.2 Bcf/d in Q1 2026, up about 4% year-on-year, per the May 2026 STEO. Pipelines do not need to bet on rig counts — they get paid on volumes.
- Industrial demand: U.S. industrial natural-gas consumption hit a record 23.6 Bcf/d in 2025 per EIA Today in Energy (May 15, 2026), and is forecast to keep rising through 2027 as reshored manufacturing comes online. Industrial is a sticky, contracted customer base.
- LNG export base: The jump from ~13 Bcf/d two years ago to a projected 17.0 Bcf/d in 2026 is mostly contracted volume, not spot. Operators of Gulf Coast feeder pipelines have visibility into that ramp.
In other words, midstream is benefiting from rising volumes and rising willingness-to-pay at the same time — a combination the sector last saw in the 2014-era shale boom, but with stronger demand-side fundamentals this time.
The bear case — in case you need one
Three risks deserve airtime before declaring the trade obvious:
- Multiples are no longer cheap. WMB at a 34x trailing P/E and ENB at 27x are not deep-value setups. ONEOK at 16.8x looks more reasonable, but it has also re-rated. A move higher in long-end yields would hit these dividend-sensitive names disproportionately.
- Pipeline approval is political. Williams’ Northeast Supply Enhancement (NESE) project and other Marcellus-to-Northeast capacity additions have been blocked or delayed for years on state-level permits. A change of stance in any individual state can move years of expected EBITDA.
- Commodity exposure is not zero. Headline midstream is fee-based, but most names have processing and gathering tails that are sensitive to Henry Hub and NGL prices. A glut scenario — warm winter, slow LNG capacity ramp, demand surprise to the downside — would compress the marginal earnings dollar.
How investors are likely playing it
The clean-line argument is that midstream is the “picks-and-shovels” expression of two of the most durable structural themes in U.S. equities: the AI/data-center power buildout and the U.S.-as-energy-exporter trade. It is hard to own those themes purely; midstream lets you own them via long-dated, contracted cash flows, and get paid 3-5% to wait. That is why the sector is being bid by income, value, and thematic-growth funds at the same time.
What to watch from here: (1) the next EIA STEO release for any revision to the 2027 LNG export forecast, (2) any state-level decision on pending Northeast pipeline expansions, and (3) the 10-year Treasury — a sustained move above 5% would be the cleanest reason for the trade to take a breather.
