Substrate Size Divergence
SemiAnalysis's annotated chart drew 27.4K views on X: 0.5x its typical post and #30 of 33 SemiAnalysis charts we track by views. Read Oct 14, 2026.
As industry attention turns to substrates, Japanese and Taiwanese ASP charts look like they're telling completely different stories.
Why it spread
It spread because the post paired a sharp Japan versus Taiwan pricing contrast with 31 likes, 3 reposts, 3 quotes, 14 saves, and 12,501 views, and the quote rate landed in the top quarter while the independent author and source reach also sat in the top quarter.
What worked
- The post text sets up a clear tension by saying Japanese and Taiwanese ASP charts look like they are telling completely different stories.
- It gives a concrete directional claim that Taiwan pricing has tripled since mid-2025 and is at an all-time high, while Japan pricing is increasing but not nearly as sharply.
- The combination of an independent author, top quarter source reach, and top quarter quote rate gave the post credibility and discussion pull beyond its 31 likes and 3 reposts.
What to borrow
We could use the same form by taking two of our own charts that show the same category moving in different directions, naming the contrast in plain language, and stating one measured change without adding extra numbers.
Careful
Do not copy the lack of a source line, the absence of self-labelling, or the missing chart description, and do not over-read the 3 quotes or 14 saves as proof of broad demand.
