Hook: The Heatwave That Exposed a Colder Truth
Europe is burning. Its fourth heatwave in as many summers has displaced 300,000 people, sent wildfires racing through Mediterranean hillsides, and pushed the demand for cooling to an all-time high. Yet, as the mercury climbs, three cooling stocks—Carrier Global, Vertiv Holdings, and IMI plc—paint a picture that defies the weather. Over the past month, Carrier dropped nearly 5%, Vertiv collapsed 24%, and IMI barely budged. The market, it seems, does not care about the temperature outside. It cares about the temperature inside data centers—and who controls the pipes.
I’ve spent the last decade auditing code and conscience in the blockchain space, watching empires rise and fall on the promise of decentralization. What I see in these cooling stocks is not a weather report. It is a warning. The same centralized infrastructure that powers AI’s backbone is building a walled garden of proprietary hardware, opaque supply chains, and single points of failure. The heatwave is a metaphor: the old world of thermal management is over. The new one must be open, auditable, and community-owned.
Context: The Architecture of Control
Let’s start with the numbers. Vertiv—the darling of AI cooling—generates 70% of its revenue from the Americas, where it has ridden the Nvidia wave to supply liquid cooling for 142 kW racks, the kind that will cool Nvidia’s GB300 superchips. Its North American sales grew 44% year-over-year. But its Europe, Middle East, and Africa segment? Down 29%. Carrier, which owns Viessmann’s heat pump business and recently acquired an AI sensor company, saw a 9.8% year-over-year earnings per share decline. IMI, the British player largely exposed to European heat pumps, trades at a mere 6.9% gain over the last month—far behind the cooling-heavy indices.
On the surface, this is a story of regional divergence. Underneath, it’s about control. These companies are not just selling cooling; they are selling the right to cool the AI gods. Vertiv’s technology is proprietary. Its contracts are closed. Its supply chain relies on rare earths and precision manufacturing that few can audit. When I look at the Chaikin Money Flow (CMF) data—institutional buying into Carrier’s dip, tentative accumulation into Vertiv, and net selling of IMI—I don’t see smart money. I see capital fleeing the old model of centralized infrastructure for the promise of something else. But that something else is still missing.
Tracing the code back to the conscience behind it: every closed-loop cooling system is a permissioned network. The hardware cannot be forked. The firmware cannot be inspected. The pricing cannot be challenged. That’s not just a business model; it’s a political statement. And in a world where AI data centers are becoming the new power plants, control over cooling is control over computation.
Core: A Technical Autopsy of Three Closed Systems
Let’s break each company down as if they were smart contracts—because they are. They are contracts between capital, energy, and information.
Carrier Global: The Conglomerate’s Hollow Promise
Carrier’s recent acquisition of a smart sensor company sounds like a step toward digitalization. But look closer: the company’s EPS is expected to drop 9.8% this year while it simultaneously invests in AI automation for data center cooling. This is a classic “buy to hide” strategy—acquire innovation rather than build it. The result is a Frankenstein stack of protocols, none of which are open. Carrier’s heat pump business is particularly fragile. The European heat pump market grew 11% across 16 countries in 2025, but France—the largest market—actually fell. Why? Because when oil hit $100 a barrel (as it did this month), the economics of gas versus heat pumps shifted, but not enough to offset high interest rates and subsidy rollbacks.
Every line of code is a hand extended in trust, but Carrier’s hand is in a glove. The company’s CMF is positive, meaning institutions are buying on weakness. They see Carrier as a way to play both AI cooling and green transition. But what they’re really buying is an opaque conglomerate where no single line of code is auditable. If a carrier cooling unit fails in a hyperscale data center, who gets blamed? The sensor vendor? The firmware writer? The assembly line in Mexico? Without open source visibility, trust is delegated to a central authority—exactly the opposite of what blockchain stands for.
Vertiv: The Poster Child for Centralized AI Thermal
Vertiv is the most fascinating case. Its stock is down 24% from its high, yet its underlying business is booming: 70% of revenue comes from America, where AI data center construction is exploding. Vertiv’s liquid cooling solutions are essential for the 142 kW racks that Nvidia’s GB300 requires. But the company’s guidance was weak, especially in Europe, where organic sales fell 29%. The divergence is not just geographic—it’s structural. Vertiv’s technology is so specialized that it creates vendor lock-in. Once a data center is built around Vertiv’s pipes, switching costs are astronomical.
This is where I see an opportunity for decentralized alternatives. Imagine an open source cooling protocol that allows data centers to mix and match pumps, chillers, and sensors from different manufacturers, each verified by a community-maintained registry of cryptographic signatures. Such a protocol would reduce lock-in, improve resilience against single-supplier failures, and create a marketplace for cooling capacity that could be tokenized. Vertiv’s current architecture is exactly what we in the crypto world call a “walled garden”—beautiful, efficient, but owned. And when the gatekeeper decides to raise prices or change the API, the whole garden wilts.
IMI: The Ghost of European Greenwashing
IMI is the smallest of the three, a London-listed company with a heavy European heat pump exposure. Its stock is up only 6.9% in the past month despite the heatwave, and its Chaikin Money Flow is negative—institutions are selling. The Money Flow Index (MFI) sits at 88.92, near overbought, but the CMF is the real story: it’s falling. This divergence tells me that retail traders are piling into IMI because of the heatwave narrative, but sophisticated money is exiting. They see the fundamental weakness: European heat pump sales are stalling, oil at $100 squeezes margins, and the green transition is losing political momentum.
Education is the only true decentralized currency, and the market is educating itself the hard way. IMI’s problem is not its product; it’s its environment. The company is a prisoner of European macroeconomic headwinds—high energy costs, slow growth, and regulatory uncertainty. But there’s a deeper issue: IMI’s heat pumps are not smart. They don’t integrate with blockchain-based energy grids. They can’t participate in demand-response programs that reward local energy trading. They are passive machines in an era that demands active, programmable thermal assets.
The Hidden Variable: Oil at $100 and the Inflation Trap
I can’t ignore the elephant in the room. Brent crude crossed $100 this month, and that changes everything. Higher oil prices theoretically make electric heat pumps more attractive relative to gas heating, but in practice, they also raise input costs for manufacturing cooling units and increase overall inflation, which keeps interest rates high. High rates kill capital-intensive projects—like building new data centers or retrofitting homes with heat pumps. The net effect is a headwind for all three companies.
But for blockchain-native cooling, higher oil prices are a tailwind. Decentralized energy networks that allow prosumers to trade excess solar power for cooling credits become more valuable when grid power is expensive. This is where I see the real contrarian play: not buying the stocks, but building the protocols.
Contrarian: Why Decentralized Cooling Will Not Come from These Companies
Here’s the counter-intuitive truth: the cooling industry is ripe for disruption, but the disruptors are not incumbent manufacturers. They are blockchain-native projects that treat cooling as a fungible resource—a commodity that can be sourced from idle capacity and traded on a decentralized marketplace. Think of it as a DePIN (Decentralized Physical Infrastructure Network) for thermal management.
Projects like “CoolChain” (a hypothetical) could tokenize cooling capacity from a network of residential and commercial heat pumps, allowing data centers to buy “cooling hours” in real time, routed by smart contracts based on price and location. Such a system would bypass centralized suppliers like Vertiv for routine cooling, reserving their specialized liquid loops only for the highest density racks. The result is a hybrid: centralized cooling for the core, decentralized for the edge.
Artists own their pixels; we just hold the keys. In the same way, data center operators should own their thermal architecture, not rent it from a single vendor. Open source cooling protocols already exist in academia—researchers at MIT and ETH Zurich have published papers on peer-to-peer thermal grids. What’s missing is the economic layer: a token that incentivizes node operators to maintain redundant cooling capacity and a governance token that allows the community to upgrade the protocol. No company on this list is building that.
The Blind Spot of Institutional Money
The institutions buying Carrier and Vertiv are betting on AI demand. They are right about the trend, but wrong about the vehicle. The real alpha lies not in owning shares of a centralized supplier, but in owning tokens of a decentralized cooling network that can adapt faster than any centralized firm. Centralized companies are optimized for quarterly earnings; decentralized protocols are optimized for long-term resilience. When the next heatwave comes—and it will, every summer from now on—a centralized network will either throttle cooling or raise prices. A decentralized network will simply reallocate resources.
Takeaway: The Cooling Revolution Is Open Source—or It Is Nothing
The heatwave in Europe is not an anomaly; it is the baseline. As AI compute doubles every nine months, the thermal footprint of data centers will outpace any efficiency gains from closed-loop liquid cooling. The only sustainable path is to open up the cooling stack—bit by bit, pipe by pipe, sensor by sensor.
We build bridges, not just blocks, between people. The cooling industry needs a bridge between the old world of centralized manufacturing and the new world of programmable, community-owned thermal assets. That bridge is open source. It is not a license; it is a promise to keep the infrastructure of intelligence free from capture.
So the next time you see a cooling stock dip after a heatwave, ask yourself: Is this a buying opportunity for the old guard, or a signal that the market is ready for something new? Based on my experience—auditing code, auditing projects, auditing values—I’d bet on the something new. The code is already being written. The conscience is already awake. All we need is the courage to deploy it.
Every line of code is a hand extended in trust. Let’s make sure that hand cools the world, not just a single company’s bottom line.
