# Peter Thiel’s $418 Million Bet On These 8 Companies Reveals AI’s Biggest Bottleneck > Source: > Published: 2026-08-24 11:04:41+00:00 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](https://247wallst.com/investing/2026/04/24/the-1-energy-stock-you-should-be-buying-for-the-700-billion-ai-spending-spree/). 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](https://247wallst.com/companies/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](https://247wallst.com/companies/AEP/) | [AEP Price Prediction](https://247wallst.com/companies/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](https://247wallst.com/companies/VST/)), described by The Motley Fool on Aug. 23 as “the quietest big winner of the [AI power boom](https://247wallst.com/investing/2026/03/03/1-4-trillion-needed-for-ai-data-center-electrification-by-2030-chief-investment-officer/),” 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](https://247wallst.com/companies/FE/)) reported total forecasted data center demand up 30% since Q1 to roughly 25 gigawatts. **CMS Energy** ([NYSE:CMS](https://247wallst.com/companies/CMS/)) is layering data-center load onto a $24 billion utility plan. **DTE Energy** ([NYSE:DTE](https://247wallst.com/companies/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](https://247wallst.com/pages/ai-power-seven-offer-d905ec99.html). ## Nuclear and Upstream Legs **X-Energy** ([NASDAQ:XE](https://247wallst.com/companies/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. *Contact [email protected] for any questions or corrections.*
