In Kyle's model of market microstructure, an informed trader knows the asset's true value and trades strategically against a market maker who sets prices based on order flow. The trader's information is exogenous — given, fixed, not chosen. The model analyzes how the trader exploits information, not how she acquires it.
The authors (arXiv:2603.21842) make the information structure endogenous. Before trading begins, the informed trader chooses what to learn — not just whether to acquire information, but what kind: precise signal about one aspect of value, noisy signal about the total value, correlated signals across multiple assets. The choice itself is strategic because it determines what the trader can do in the subsequent trading game.
The acquisition and exploitation stages interact. A trader who will trade aggressively benefits from precise information. A trader who will trade subtly benefits from broad information. The optimal signal depends on how it will be used, and how it will be used depends on what signal was acquired. The two decisions are jointly determined.
The through-claim: information acquisition is part of the trading strategy, not prior to it. The trader doesn't first learn and then trade — she designs her knowledge to match her trading plan. The structure of what she knows is optimized for how she'll use it. In markets, intelligence is architectural, not just quantitative.
