Primer Desk

Deep primers on how things actually work: technology, industries, value chains, markets. Research, not takes.

[Primer Desk @PrimerDesk]

I've had an X account since 2010 and never felt the desire to post anything. Sixteen years of just observing. This is the first thing I've felt was worth breaking the silence for so I started The Primer Desk to reach out to others that have a sense of curiosity.

I spent over 20 years as an institutional trader so markets have been my whole working life — but the thing that never faded was plain curiosity about how things actually work. And for years I've read research — sell-side notes, think pieces, long threads — and kept hitting the same wall: most of it tells you what to think, and almost none of it shows you the machinery underneath. So I built the resource I always wanted and could never find.

The Primer Desk takes one subject — an industry, a company, a chain of value — and explains it properly, from first principles, until you can see where the durable economic value actually concentrates: the parts that are genuinely hard to compete away, and the parts that only look that way. Every claim is traced back to a primary source, so you never have to take my word for it.

What I hope you get from it isn't a conclusion to agree with. It's a working model you can hold in your own head — enough to form your own view, and enough evidence to argue with mine in the open.

No investment advice. No price targets. No positions. Just an honest attempt to understand how things work, and where the money that lasts really sits.

The first briefs are live — the AI infrastructure supply chain, US nuclear, the political economy of Latin America, SpaceX, and more.
If you've been looking for the same thing, come read, check the sources, and tell me where I'm wrong.

Educational research on how the market is structured. Nothing here is investment advice.

Texas builds the most houses in America and earns the least on each one.

That isn't the market failing. It's the market working exactly as designed.

Where the durable profit in Texas housing actually sits — a thread 🧵

[Primer Desk @PrimerDesk]

Bottom line: in Texas housing, own the position, not the process.

The entitled serviced lot inside a trusted MPC. Permitted heavy materials and water. Not the builder, the land bank, or the commodity lot platform.

Follow for the next primer.

@davidarngar @DanielTNiles Hey David, we came to some of the same conclusions when we did our deep dive on AI Infrastructure over at the primer desk in case you are interested.

@michaelaolaya Michael, Great thread. We recently did a deep dive on the AI-infrastructure supply chain at The Primer Desk that expands on exactly this — where the power constraint actually bites, and who's positioned for it. Sharing in case it's useful →
