The lesson
Publish your own transaction data as a recurring public index, with the summary, chart and full table on one page.
"Ramp AI Index" opens with a bulleted summary (Anthropic at 60.1% of AI token spending, AI adoption at 55.9% of U.S. businesses on Ramp) above a line chart against Census estimates. Below it sit one dense table of adoption by vendor, sector and size, a Tokenomics table, then a Subscribe on Substack button and a Methodology section.
Don't imitate the topic or tables if your data isn't proprietary. Keep the recurring cadence, the quotable summary on top, and an honest methodology block.
