Thirteen sectors of the AI economy. A lit sector has a thesis with questions; a dark one lights up when its first thesis arrives.
Semiconductors & Compute Silicon
2 theses7 questions
Who designs, makes and equips the logic chips that do AI compute.
Memory & Storage
No thesis yet
The memory and storage that feed the accelerators and hold the data.
Networking, Interconnect & Optics

What moves data between chips, servers, racks and data centers.
Hyperscalers, Cloud & Compute Services
6 theses26 questions
pulsehouse 64machines 71

9 theses39 questions
pulsehouse 66machines 72
Who lends to, invests in and insures the buildout, and on what terms.
The pulse of a sector: the mean chance that the Call’s side wins over the sector’s open questions with a known side, read three ways (the house, the readers from five, the machines); it shows from two questions.
The pulse, three ways
One index per sector, read by the house, by the readers and by the machines. When the three part by 10 points or more, that is a story.
| Sector | House | Readers | Machines | Spread |
|---|---|---|---|---|
| Foundation Models & AI Intelligence | 76 | — | 84 | 8 |
| Hyperscalers, Cloud & Compute Services | 64 | — | 71 | 7 |
| Power, Energy & Grid | 75 | — | 82 | 7 |
| AI Financing, Credit & Capital Structure | 66 | — | 72 | 6 |

Semiconductors & Compute Silicon
Hyperscalers, Cloud & Compute Services
Is the marginal buyer of AI compute real?
Is the capex spending defense, or is the return not there?
Does the hardware hold its value?
Do the orders turn into profit?
Is AI revenue arriving fast enough for the biggest spenders to pay for their data centers out of their own cash?
How much of the money buying AI chips was lent, guaranteed or invested by the companies selling them?

AI Financing, Credit & Capital Structure
Is the marginal buyer of AI compute real?
SpaceX after the IPO: exit liquidity, or the next ten-bagger?
The debt behind the machines: 1999 capex, 2008 credit, or neither?
Why did the long end climb after the hike: growth, debt, or a missing buyer?
Who writes the checks for the buildout?
Does the hardware hold its value?
Can the AI trade survive a 10-year Treasury above 5% and an oil shock at the same time?
How much of the money buying AI chips was lent, guaranteed or invested by the companies selling them?
How much of the AI buildout is debt the balance sheets do not show yet, and who carries it if a tenant walks away?
