DataSnack's read

Apple leads on policy exposure, not earnings, and Nvidia's report can reverse it

The race matters because it shows how investors price AI regulation and AI-driven costs across AI-linked valuations. The model's case rests on short-run moves in Apple's 63% chance partly reversing, giving 68%, though it trails no-change.

How the model works

Apple and Nvidia are only about $149 billion apart and swap the top spot on daily moves. The model starts from the market's own number, applies the partial pull-back, then adds the day's change in the reading of stories that Nvidia has retaken the top spot, so a real swap in standing can carry the number.

• About 0.301 in log-odds of each recent move in Apple's chance carries into next week, so a negative number means the move partly reverses. DataSnack's author expected -0.339 in log-odds; the data say 0.301 in log-odds ± 0.066. A rough rule.
• Each full point the reading of Nvidia retaking the top spot rises in a day moves Apple's chance of being largest by about 0 in log-odds in log-odds. DataSnack's author expected -0.5 in log-odds; the data say 0 in log-odds ± 0.28. A rough rule.
