Acquisition Supply Dataset 2026

167 U.S. industries at four digit NAICS: 152 ranked and 15 unranked low confidence. The top 100 is by index score.

Business Buyer School calculation and score. These counts measure how many small firms exist, not how many are for sale. The top 100 is the 100 highest scores on the Acquisition Supply Index, which combines density, share and count of small firms; it is not a ranking by pool size.

Business Buyer School Report 3, shown separately and not part of the index

This is the data behind the full study and the short version. How it was built is on the methodology page. The index is largely a measure of how small an industry's typical firm is; the staffed small firm counts are a separate lens.
