Who owns the robots, the power, and the compute

The public argument in technology is still the video: a humanoid doing a backflip, a warehouse tote changing hands on a clean floor, or a benchmark chart in a launch post.

Machine Economy is a daily file and research desk about the other half of the page. Everyone watches the flashy robot demos and LLM benchmarks. Almost nobody tracks the supply chains, the unit economics, and the physical bottlenecks that decide whether a machine can actually be built, plugged in, and kept on a shift.

We cover three layers, in the order the physical world imposes them:

1. The Robots (The Bill of Materials and the Shift)

The industry has moved past whether a machine can walk. The question inside a buying committee is whether anyone can afford to build it at volume and keep it working.

Humanoids get the photograph, but the work—and the cost—is in the stack. Actuators alone account for roughly 56 percent of a humanoid’s bill of materials: the harmonic drives, planetary roller screws, strain gauges, and brushless motors where heat and failure actually live. Structure and battery packs take another 26 percent; sensors and edge compute take the rest. A precise joint does not get cheap because a demo looked fluent.

On the factory floor, the sticker price is secondary to utilization. An industrial lease at $8,500 a month is $51 an hour on a single eight-hour shift—well above the warehouse wage the robot is meant to stand beside. Only when a machine runs three shifts—roughly 6,000 hours a year, without waiting on a charger or a human reset—does the math drop toward $17 an hour. Western labs currently lead on world models. The metal is a different contest, run down Tier-1 automotive supply lines. We report on who makes the joints, who placed the firm order, and what is actually on a customer floor versus what is still a memorandum of understanding.

2. The Compute (The Silicon and the Tactile Record)

The models behind physical AI are being bought at a scale that no longer looks like ordinary corporate spending, with hyperscaler capital expenditure tracking toward $1 trillion and single frontier campuses pricing near $41 billion per gigawatt.

But compute spent on internet text and video has a ceiling. A language model can describe a doorway; a robot has to pass through it without taking the frame along. A model trained on video can look fluent and still put a foot through wet snow, because a video frame does not contain friction, glare, or contact force. Closing that gap requires tactile failure data recorded in the physical world, and edge silicon small enough to run vision-language-action models without waiting on a distant data centre.

3. The Power and Infrastructure (What Can Actually Run)

A data centre cluster or an automated fleet is only as real as the megawatts behind it. Compute schedules are now governed by gas turbine bookings, transformer lead times, grid interconnection queues, and cooling water.

Alongside physical power, we track machine infrastructure and decentralized physical networks (DePIN)—strictly when they change what a machine can do. Our filter is simple: if you remove the token and the price chart, does a robot, a fleet operator, or a data buyer still have a reason to care? A machine identity tied to a secure element that survives a repair or an ownership transfer is infrastructure. A simulated door in a press release is not.

How This Desk Works

  • The headline states the constraint. If a press release announces a 10,000-robot target, a benchmark lead, or a gigawatt turbine booking, our headline notes whether the order is actually placed, whether the model is on sale, or whether the turbines are running.
  • The timeline and the file. Daily breaking updates and chart notes are filed first on X at @MechEconomy. www.machineeconomy.co.uk is the permanent record: daily briefings, Q4 supply-chain models, and plain-English primers on the hardware stack.
  • The weekly letter. Every Friday morning, we send the week’s filings by email. The news and the numbers only. No advertisements, no sponsored tokens, and no filler.
