Key findings
- Accenture leads this sample alone, named in 198 of 322 ChatGPT responses (61.5%) to the question “What are the best managed IT service providers?”, collected August 8, 2026–October 1, 2026.
- 15 firms cleared the reporting threshold on “What are the best managed IT service providers?” in ChatGPT as of October 1, 2026; the full table with response counts is below.
- Dataprise appears in 6 of the 16 managed IT service providers reports published by The Shortlist Report, the widest coverage of any firm named on this page.
- No firm paid to appear in this ranking; placement cannot be bought, and the counts come from ChatGPT responses rather than from submissions.
Why the tiers fall where they do
Tier 1 holds Accenture, named in 198 of 322 ChatGPT responses (61.5%). No other firm in this sample comes close enough to be grouped with it.
Tier 2 holds Kyndryl and NTT, named in 173 to 184 of 322 responses (53.7–57.1%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
Tier 3 holds CDW and Ntiva, named in 133 to 157 of 322 responses (41.3–48.8%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
Tier 4 holds IBM, Thrive, Rackspace, SHI, HCLTech and Dataprise, named in 110 to 122 of 322 responses (34.2–37.9%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
Tier 5 holds Cognizant, DXC, Wipro and Presidio, named in 90 to 106 of 322 responses (28.0–32.9%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
The test is McNemar’s at 95%, applied against the same 322 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
Accenture leads on its own, named in 198 of the 322 responses to this question (61.5%).
367 firms were named at least once across the sample. 15 of them cleared the threshold of 2 responses and appear above; the rest were named once and are inside the noise.
How to read this
Firms are grouped into tiers, not ranked one to fifteen. A tier holds every firm whose 95% confidence interval overlaps the leader's, which is a long way of saying the sample cannot tell them apart. Order within a tier is arbitrary — read the counts, not the position.
Share is the percentage of responses that named the firm — not a quality score. A firm scoring low here may be excellent and simply under-written about online, which is a finding about its visibility rather than its work.
The same question was asked repeatedly because AI assistants do not answer identically twice. A single response would tell you almost nothing.
What this measurement does not tell you
- It is not a quality ranking. Share reflects how much has been written about a firm online, which is what an AI assistant reads. A capable firm nobody writes about scores low here.
- It is a reading from a date range, not a permanent standing. This sample was collected August 8, 2026–October 1, 2026; models change and so do their answers.
- It covers ChatGPT only. Other assistants answer differently, and we do not extrapolate across engines we have not measured.
- Order within a tier is arbitrary. Read the counts, not the position. Why we use tiers.
