Thiel Macro LLC resurfaced in mid-August with a $418.7 million book spread across exactly eight positions as of June 30, 2026, according to 13f.info’s rendering of the filing. Seven of the eight are bets on the physical energy bottleneck constraining the AI buildout. The eighth is Amazon, the company creating the bottleneck.
This is a point-in-time snapshot of long US equity positions only. It excludes shorts, derivatives, private stakes, and non-US listings. It is Thiel Macro LLC’s disclosed book, not Peter Thiel’s personal wealth, and the filing states no reasoning for any holding.
Eight Positions, One Thesis #
Per 13f.info and Quiver Quantitative, the disclosed positions are Amazon at $118.0M (28.2%), Vista Energy at $75.9M (18.1%), Vistra at $59.1M (14.1%), American Electric Power at $42.2M (10.1%), DTE Energy at $40.3M (9.6%), FirstEnergy at $39.9M (9.5%), CMS Energy at $39.6M (9.4%), and X-Energy at $3.7M (0.9%). HedgeCo.Net corroborated the eight-name structure on Aug. 19, 2026.
The market noticed Vista first. Shares of Vista Energy (NYSE:VIST) closed at $68.31 on Friday, Aug. 14, and $72.16 on Monday, Aug. 17, a close-to-close move of 5.64%. The pop faded. Vista finished at $69.58 on Friday, Aug. 21, below the Aug. 17 close. The fund disclosed a stake in a stock already up 42.99% year to date and 1,568.59% over five years.
Power, Not Chips, Is the Constraint #
The seven bottleneck plays reflect a visible mechanism in utility earnings calls: expanding existing generation is cheaper and faster than building new capacity, and hyperscaler demand arrives before new plants can be permitted. American Electric Power (NASDAQ:AEP | AEP Price Prediction) disclosed 69 gigawatts of contracted load additions through 2030, backed by a $78 billion five-year capital plan, and is advancing a 10-gigawatt Ohio project with SoftBank and federal agencies announced around March 2026.
Vistra (NYSE:VST), described by The Motley Fool on Aug. 23 as “the quietest big winner of the AI power boom,” leverages an existing nuclear-heavy fleet plus the pending Cogentrix deal. CEO Jim Burke framed the Helix venture with NVIDIA, KKR, and the Kuwait Investment Authority as a “rack-to-grid, one-stop-shop solution.” FirstEnergy (NYSE:FE) reported total forecasted data center demand up 30% since Q1 to roughly 25 gigawatts. CMS Energy (NYSE:CMS) is layering data-center load onto a $24 billion utility plan. DTE Energy (NYSE:DTE) has 2.4 gigawatts of executed agreements, anchored by a 1.4 GW Oracle facility and a 1 GW Google contract.
Utility Dive’s first-quarter 2026 roundup described utilities as “divided on data centers” over ratepayer affordability. That tension applies squarely to DTE, FirstEnergy, and CMS, and it is the same picking-shovels-not-gold angle we broke down across seven non-chip AI beneficiaries in a free report on the power, cooling, and networking names behind the buildout.
Nuclear and Upstream Legs #
X-Energy (NASDAQ:XE) completed its Nasdaq IPO in April 2026, raising approximately $1.1 billion net. The fund disclosed a stake in a company public for roughly one quarter. X-Energy’s 144-reactor pipeline across the US and UK, roughly 11.5 gigawatts electric, is anchored by Dow, Amazon, and Centrica. Amazon invested roughly $500 million in X-Energy’s Series C-1 round announced Oct. 16, 2024, targeting more than 5 gigawatts of SMR capacity by 2039. The fund disclosed both the reactor supplier and its largest announced customer. Shares closed at $18.67 on Aug. 21, down from the $29.20 April 24 open.
Vista Energy is harder to read. It is the largest independent operator in Argentina’s Vaca Muerta shale, producing 134,700 boe/d in Q1 2026, with extraction costs near $4.30/boe. Direct reporting framed the stake as a conventional oil and gas position tied to Thiel’s ties to the Milei administration. Crusoe Energy Systems announced a 2026 Vaca Muerta digital flare mitigation project with local partner Unblock, placing containerized data centers at wellheads. Vista has no confirmed AI power contract.
Demand-Side Anchor #
Amazon sits alone on the other side. AWS revenue reached $42.2 billion in Q2, up 36.7% year-over-year, the fastest growth in 18 quarters, with Q2 cash capex of $53.1 billion. One analyst cited in coverage put hyperscaler capex broadly at $1.5 trillion to $1.6 trillion by 2027. Amazon’s own X-Energy check makes it an active participant solving its own power problem.
Read together, the disclosed book reads as a wager on the physical resource AI growth is straining. Whether the thesis holds depends on rate cases, ERCOT and PJM queue reviews, and NRC construction-permit decisions expected over the next three quarters.
