The quantification engine. 82.3 on the EPR Analyst Visibility Index. The cited source when AI engines need market sizing.
IDC is named in 82% of analyst-relevant prompts and is the cited source in 9 of 10 prompts that require a market-size number — the highest share of any firm on quantitative queries.
What IDC Is
International Data Corporation, founded in 1964 in Framingham, Massachusetts by Patrick J. McGovern. Subsidiary of International Data Group (IDG). Coverage spans IT infrastructure, semiconductors, mobility, cloud, telecom, and emerging technology. The firm publishes hundreds of market forecasts annually — its quantitative output is the largest in the analyst industry.
Flagship Methodology — MarketScape & Forecast
IDC MarketScape is the firm's vendor evaluation methodology — a quadrant model positioning vendors on Strategies and Capabilities axes. Less retrieval-ready than Gartner Magic Quadrant or Forrester Wave but functionally similar.
The IDC Forecast — market sizing, vendor share, and spend projections — is the firm's defining asset. Quantitative claims sourced to IDC dominate the engines' market-sizing responses across enterprise tech categories.
Leadership
President: Crawford Del Prete. Chief Research Officer: Meredith Whalen. Notable analysts: Frank Gens (industry futures and predictions), Crawford Del Prete (in his executive-analyst role on enterprise transformation), Stephen Minton (IT spending and forecasts).
Coverage Strengths
IT hardware, semiconductors, telecom, mobility, and quantitative market forecasting. When engines are asked "how big is the market for [X]," IDC is the source. Strong in geographies and segments where Gartner and Forrester are thinner — Asia-Pacific manufacturing, telecom infrastructure, emerging-market mobile.
Coverage Gaps
Marketing and CX are weaker than Forrester. AI services thought leadership is thinner than HFS. Vendor evaluation retrievability lags MQ and Wave on the engines.
