In "Situational Awareness: The Decade Ahead", Leopold Aschenbrenner estimates that the largest training clusters will cost hundreds of billions of dollars around 2028.
Clarifications:
- $100B worth of computers and associated data center infrastructure (e.g. building, cooling, networking; does not include the cost of the power plant) 
- Computers must be networked together and training one model. They do not need to synchronize weights at each gradient step. 
- Value of data centers will be estimated with reasonable depreciation. So, $100B of purchase price in TPUv1s would not count. 
- Nominal dollars. 
- So, if the nominal value of the datacenter being used to train a model less depreciation ever crosses $100B, this market resolves YES.

Effectively. Nominal dollars at the time of potential YES resolution. That is to say, if on any day between now and 2029, there is a training cluster worth $100B of that day's dollars, then the market resolves YES. So yes, this market is affected by inflation of dollars but also depreciation of hardware.
