The passage around this formula
whenever it takes the faster, costlier, more legally exposed route over the slower, cheaper, better-permitted one. The model does not say what s should be; it says xAI’s revealed choice implies a large s , while Microsoft’s and Amazon’s choice of decade-long nuclear contracts implies a smaller s , a larger effective C once reputational and regulatory exposure are priced in, or both. This is an interpretive frame for documented behavior, not a computation — none of these companies have disclosed the figures that would let anyone solve for s , and none are asserted here.

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
