How a credit is earned
A firm earns one sell-side credit when a public source linked on the deal row names it as financial advisor to the seller. One credit per deal per firm. 2 of the 22 credited deals name more than one sell-side advisor, which is why 22 deals produce 24 credits. Buy-side roles are shown in their own column and do not count toward the rank. Legal, tax and diligence advisors are excluded. A deal belongs to this page when the index labels its sector data infrastructure. The full methodology sits on the all-sector league table.
What this table is not
It is not market share. 161 of the 183 tracked data infrastructure deals name no sell-side advisor, so a credit count measures disclosure, not deal flow. A firm that closed quiet founder exits in this sector shows up here with a zero or a one.
It is not a quality ranking. Large banks cluster near the top partly because their deals involve public companies and sponsors who publish press releases and file 8-Ks. Do not pick an advisor from a league table. Ask for their last three closed deals in your size band and call the founders.
Small counts are noisy. The index holds only 22 data infrastructure deals in 2026 with a named sell-side advisor, so one extra announcement can move a firm several places. 19 of 21 firms have a single credit.
