Lesson & Term of the Day

Today's lesson

What is a Compute Reservation?

A compute reservation secures defined GPU or accelerator capacity for a buyer over an agreed period. Why it matters today: Today's lesson connects the Compute Market Structure track to the compute market readers are watching.

Term of the Day

Capex

Capex, or capital expenditure, is money spent on long-lived assets such as data centers, servers, chips, power equipment, and networking. AI infrastructure requires heavy capex because capacity must be built before it can generate revenue.
