International Data Corporation (IDC)
Definition
International Data Corporation (IDC)
International Data Corporation (IDC) is a global tech market research firm covering IT, telecom, and consumer sectors in 110 countries. Founded in 1964, IDC issues forecasts, surveys, and vendor rankings that shape how enterprise IT buyers plan their yearly tech spend.
The firm sits inside International Data Group (IDG), the private research holding company. IDC’s Needham, Massachusetts headquarters coordinates more than 1,300 analysts across regional offices.
Tracker programs log quarterly shipments, software revenue, and services bookings across every major technology category. Regional practices in London, Sydney, Beijing, and São Paulo add local context for buyers who need country-level demand splits.
Outsourcing operators lean on IDC’s data for two reasons, the trackers turn shipment counts into realistic demand curves, and the vendor MarketScapes name the providers buyers already trust. Both signals feed pricing and capacity decisions.
Key takeaways
- IDC operates in 110 countries and covers technology, telecom, and consumer buyer behaviour.
- Trackers, forecasts, and MarketScape reports drive vendor selection at Fortune 1000 buyers.
- IDC data anchors quarterly briefings inside cloud, semiconductor, and BPO strategy teams.
- The firm holds ~1,300 analysts across regional practices, with Needham HQ setting methodology.
How it works
IDC operates through three product families: syndicated research, custom advisory, and industry events. Analysts publish trackers, forecasts, and MarketScape vendor evaluations that clients access via the IDC portal.
Trackers are the flagship. Each covers a category (PC, smartphone, server, storage, public cloud computing services), logging unit shipments and revenue every quarter and feeding models that project three to five years out.
Coverage cycles matter. IDC updates most trackers on a 90-day cycle, though monthly releases exist for fast-moving categories like public cloud infrastructure and enterprise storage systems. Historical data goes back a decade or more.
The catalogue splits three ways:
| Product | Format | Typical buyer |
|---|---|---|
| Trackers | Quarterly datasets | Vendors, investors |
| Forecasts | Annual reports | Strategy teams |
| MarketScape | Vendor rankings | Procurement leaders |
On the firm’s own count, IDC tracks 15 billion data points annually across more than 800,000 companies, with a research desk that services buyers, sellers, and investors on the same feeds.
MarketScape evaluations use a 2×2 quadrant covering strategies and capabilities. Vendors get rated on price, delivery breadth, product roadmap, and customer sentiment. Procurement teams then use the diagram to shortlist finalists inside RFP processes.
Pricing runs on subscription tiers. A single-analyst desk sits at four figures, while enterprise-wide access with custom advisory reaches into six figures — the trade-off is coverage depth versus report count.
Analysts also field custom advisory requests. A cloud vendor might commission a sizing study; a private equity firm might request an update on the KPO delivery mix. These engagements sit outside the syndicated feed.
Examples
Named vendors use IDC output to size markets and validate roadmaps. The MarketScape circle diagrams double as sales collateral, while the trackers give investors a comparable read on quarterly shipment trends across public and private technology providers.
AWS cites IDC forecasts in re:Invent keynotes to size the addressable cloud market, most recently pinning worldwide public cloud services spending at figures IDC tracks per quarter.
NIST’s $874 million semiconductor R&D program leans on market context that IDC and peer analysts publish, since federal R&D allocations weigh against private-sector chip forecasts.
Lenovo, HP, and Dell rank quarter after quarter inside IDC’s PC Tracker, which is why release day still moves procurement conversations across enterprise IT buyers in North America and Europe.
Financial analysts on the sell side cite IDC’s Worldwide Semiconductor Application Forecast when they model chip demand, since it splits shipments by end use (automotive, industrial, data center, mobile).
Private equity firms scan the MarketScape shortlist before evaluating acquisition targets in software and services. When IDC ranks a vendor as a Leader, valuation multiples usually move a notch upward at term-sheet stage.
Outsourcing operators — global BPO, KPO, and contact center providers — use IDC’s Worldwide Services Tracker to time capacity investments and price against real market growth.
