The video sorts AI infrastructure into three lanes and assigns one company to each: Amphenol for connections, nVent for cooling, Eaton for power. The headline numbers it cites are all real, and I traced each one to a filing, an earnings call, or a conference appearance. The lanes are the problem: Eaton closed its acquisition of liquid cooling maker Boyd Thermal on March 12, 2026, which puts it in nVent's business more than six months before this video was posted. The "no matter whose chip wins, these three get paid" thesis also rests on an exclusivity that NVIDIA's own published partner list contradicts.

This is a summary of someone else's stock thesis and a fact-check of the claims in it. It is not investment advice, and nothing here is a buy or sell recommendation.

Amphenol: 63% is right, but it describes an end market, not a business unit

The video says Amphenol's "data center and networking business grew 63% just last quarter." The number is accurate. The unit is wrong.

Amphenol reports three segments: Communications Solutions, Harsh Environment Solutions, and Interconnect and Sensor Systems. There is no "data center and networking" segment. IT datacom is an end market that Amphenol discusses on earnings calls and sits mostly inside Communications Solutions.

For Q2 2026, the quarter ended June 30, 2026 and reported on July 29, 2026, CEO Adam Norwitt said on the call: "The IT datacom market represented 43% of our sales in the quarter," at $3.784 billion, "growing 89% in U.S. dollars and 63% organically." So 63% is the organic rate for an end market that now makes up 43% of the whole company.

The segment that contains it grew differently. Communications Solutions posted $5,383.6 million, up 85% in U.S. dollars and 42% organically. Total company sales were $8,758.1 million, up 55% reported and 30% organically, with a book-to-bill of 1.23:1 and adjusted operating margin of 29.8%.

The 26-point gap between 89% reported and 63% organic is acquisitions. Amphenol's own release credits "contributions from the Company's acquisition program." The largest contributor is CommScope's Connectivity and Cable Solutions business, which Amphenol closed in January 2026. Anyone citing the 89% figure as organic AI demand is double counting a purchase.

The video also says Amphenol supplies parts to NVIDIA's own AI systems. Amphenol does not name customers in its quarterly release or on the call, so that specific claim cannot be checked against a filing.

nVent: the name is nVent Electric plc, and the $2 billion came from a call, not a filing

Whisper transcribed the company as "Envent." The correct name is nVent Electric plc, ticker NVT, with a lowercase n and a capital V. It is an Irish-domiciled plc, the same corporate form as Eaton.

The $2 billion claim is real and comes from CEO Beth Wozniak on the Q2 2026 earnings call on August 4, 2026: "We expect our total data center sales to be $2 billion in 2026, more than double last year's sales." It does not appear in the quarterly press release filed with the SEC, so it is forward guidance stated verbally, not a reported result.

On whether the doubling is organic: Q2 2026 sales were $1,471 million, up 53% reported and 47% organically. CFO Gary Corona said acquisitions added $52 million to sales, or 5 points of growth. Systems Protection, the segment that carries the liquid cooling and rack business, grew 70% with 7 points from the Electrical Products Group acquisition, leaving 62% organic. So the data center growth is mostly organic.

The company producing those numbers is not the company from two years ago. nVent sold its Thermal Management business in January 2025, acquired Trachte in July 2024, and acquired Avail Infrastructure Solutions' Electrical Products Group in May 2025. It now reports two segments, Systems Protection and Electrical Connections, rather than the older three-segment structure. Year-over-year comparisons span a reshaped portfolio even when the organic line looks clean.

On NVIDIA: nVent joined the NVIDIA Partner Network in 2025 and publishes a page about collaborating with NVIDIA on liquid cooling for GB200 NVL72 deployments. The NVIDIA Partner Network is a channel and solutions program. Membership is not the same thing as being designed into a rack.

Wozniak's own framing on the call is the more useful number: liquid cooling is currently 10% to 15% of data center cooling, with a modular liquid cooling platform launching in fall 2026. The runway is the argument. The lock-in is not established.

Eaton: 85% is real, and the number came from a conference stage in September

The video says "last quarter, their data center orders were up 85%." That figure exists, but it is not in Eaton's Q2 2026 results.

Eaton's Q2 2026 release reported revenue of $8.5 billion, up 21% with 14% organic growth. Electrical Americas hit a record $4.0 billion with 27.5% operating margins and 18% organic growth. Electrical Global hit a record $2.5 billion at 19.8% margins and 18% organic growth. Rolling 12-month orders were up 41% in Electrical Americas and 33% in Electrical Global. Backlog rose 33% in Americas and 103% in Global. Book-to-bill in the electrical businesses was 1.2.

None of those are data center specific. On the July 31, 2026 earnings call, CEO Paulo Ruiz said "data center organic revenues were up 65% and much, much faster than the underlying market," which the company put at 23%. CFO David Foster said the Electrical Americas negotiations pipeline was up 60% year to date.

The 85% orders figure came later. Ruiz gave it at Morgan Stanley's Laguna Conference on September 17, 2026, eleven days before this video posted: data center revenue up about 65%, orders up about 85%, negotiation pipeline up more than 130%. The on-screen clip in the video is a third-party post summarizing that appearance.

The more interesting number Ruiz gave at Laguna is content per megawatt. Eaton's content was $1.5 million per megawatt in cloud applications and $3 million in AI applications, rising to $3.4 million after the Boyd acquisition. That is the actual mechanism behind the growth, and the video does not mention it.

NVIDIA wrote the 800 VDC spec first and named three power vendors

The video says Eaton was "picked by NVIDIA to help redesign how power gets into their next generation AI racks." The chronology runs the other way, and the list is longer than one name.

NVIDIA published the 800 VDC architecture on its developer blog on May 20, 2025, targeting 1 MW racks with full-scale production aligned to Kyber rack-scale systems in 2027. That same post named the ecosystem:

  • Silicon providers: Analog Devices, Infineon, Innoscience, MPS, Navitas, OnSemi, Renesas, ROHM, STMicroelectronics, Texas Instruments
  • Power system components: Delta, Flex Power, Lead Wealth, LiteOn, Megmeet
  • Data center power systems: Eaton, Schneider Electric, Vertiv

Eaton is one of three named power systems vendors, alongside two direct competitors. Eaton then published its own 800 VDC reference architecture at the OCP Global Summit in October 2025, explicitly in support of the architecture NVIDIA had announced. ABB separately announced its own 800 VDC collaboration with NVIDIA. Trade coverage describes ABB and Eaton as co-anchoring the standard rather than either being uniquely chosen.

NVIDIA set the spec. Vendors aligned to it. That is a different story from a sole-source design win, and it matters because a published architecture with a dozen-plus named partners is closer to an open standard than a moat.

The three lanes already overlap

The video's thesis needs each company to own its niche. None of the three does.

Eaton completed its acquisition of Boyd Thermal on March 12, 2026, a liquid cooling business with more than 6,000 employees and plants in North America, Asia, and Europe. Ruiz said the goal was an integrated grid-to-chip offering. Eaton now sells the thing the video assigns to nVent, and the Boyd deal is what pushed Eaton's content per megawatt from $3 million to $3.4 million.

In connectors, Amphenol competes with TE Connectivity, Luxshare Precision, Molex, and Corning. TE's Digital Data Networks business has been posting its own AI-driven growth. In power, NVIDIA's own partner list puts Eaton next to Schneider Electric and Vertiv, with ABB building to the same 800 VDC spec. In cooling, nVent competes with Vertiv, Schneider Electric, and now Eaton.

Each of these companies is growing fast off genuine AI demand. The growth rates in the video check out. The step the video skips is from "this company is growing" to "this company cannot be replaced," and the evidence for the second claim is thinner than the first.

Key Takeaways

  • Amphenol's 63% is correct as the organic growth rate of the IT datacom end market in Q2 2026, which was 43% of company sales at $3.784 billion. It is not a segment, and the 89% reported figure includes the CommScope CCS acquisition.
  • nVent's $2 billion data center figure is 2026 guidance that CEO Beth Wozniak gave verbally on the August 4, 2026 call. It is not in the SEC filing. The underlying growth is mostly organic, with acquisitions adding 5 points in Q2.
  • Eaton's 85% orders growth is a real number, but it came from the CEO at Morgan Stanley's Laguna Conference on September 17, 2026, not the Q2 release. The quarterly filing's data center disclosure is 65% organic revenue growth, stated on the earnings call.
  • NVIDIA announced the 800 VDC architecture in May 2025 and named Eaton, Schneider Electric, and Vertiv as data center power systems partners, plus ten silicon and five component vendors. Eaton's reference architecture came five months later, in support of that spec.
  • The clean three-way split is already broken. Eaton bought Boyd Thermal in March 2026 and sells liquid cooling in direct competition with nVent.
  • The company name is nVent Electric plc. The whisper transcript's "Envent" is a transcription error.
