Gartner Market Share Momentum

Market Share Momentum (MSM) is a proprietary Gartner publication that projects the future trajectory of vendor market share and revenues based on recent historical performance, peer-index performance and forecasted market conditions. It provides a comprehensive view of how a vendor's prior-year momentum positions them for future market share outcomes if they continue to operate at that trajectory. 

MSM empowers clients to make data-driven strategic decisions without internal bias. Opportunities clients can leverage this publication include: 

• Benchmarking Performance: Compare projected vendor performance by market and region for competitive benchmarking. 
• Validating Strategies: Compare your internal revenue goals against Gartner's projections for your respective market segment(s) and validate your go-to-market strategies. 
• Identifying Risks and Opportunities: Spot rising competitors early, identify which market segments are poised for disruption, and understand where market dynamics are shifting. 
• Scenario Planning: Evaluate what your future market share trajectory looks like if current trends and momentum persist. 

The initial launch of Market Share Momentum is scheduled for July of 2026. 

MSM is built upon Gartner's proprietary data and intellectual property. It depends on two core publications: Gartner's Market Share results (annual for most markets, quarterly for others) and our quarterly Market Forecasts. The methodology combines these inputs using two distinct elements: 

• Peer-Indexed Performance (PIP): An algorithm used to evaluate past performance by measuring a vendor's momentum relative to its peers. 
• Forecast-Constrained Revenue Gap Analysis: A proprietary process that identifies the "gap" between historical vendor performance and the overall market outlook. MSM projections are calibrated to Gartner’s published market forecasts, ensuring that the aggregate market outlook is reflected in individual vendor trajectories. 

Peer-Indexed Performance (PIP) is a proprietary Gartner metric that measures a vendor’s growth against the collective growth rate of its market peer group, excluding the vendor itself. By normalizing performance against this peer average, PIP objectively shows how much a vendor is outperforming or underperforming the broader market. A positive PIP indicates the vendor is gaining market share at the expense of competitors, while a negative PIP signals a loss of market share relative to peers. A Peer-indexed performance growth rate of 5% would convey that a vendor grew at a rate of 5% above that of their peers in a market (not the market overall). Likewise, a PIP growth rate of -5% would convey that a vendor grew at a rate of 5% below that of their peers in a market (not the market overall).

Each MSM report covers a four-year period for each market or segment. The first two years reflect historical estimated vendor revenues sourced from the most recent Market Share publications. The following two years provide forward-looking trajectory projections based on recent peer-indexed performance momentum, and Gartner published forecasts. 

Gartner’s Market Share methodology and the Financial Statement Scorecard are distinct and complementary tools. The Market Share methodology leveraged by MSM provides Gartner’s independent estimates of vendor revenue within specific market segments. These estimates may incorporate a range of inputs (including public financial statements, supplemental disclosures, and proprietary research) but are ultimately adjusted to align with Gartner’s market definitions and segmentation standards. As a result, even for public vendors, published financials are not used “as-is”; instead, they are evaluated and, if necessary, adjusted to reflect only the revenue relevant to the defined market segment. 

The Financial Statement Scorecard, by contrast, is used to assess a vendor’s overall financial health and viability based on standardized financial ratios from public filings. While both methodologies may leverage public financial data, the Scorecard focuses on financial strength, while Market Share estimates focus on market positioning and segment-specific revenue for the markets within which the vendor participates. 

Gartner’s Market Share encompasses realized IT technology revenues across Gartner covered markets. All revenues outside of Gartner-covered Market Share markets are not included (i.e. vendor advertising revenues as an example). Gartner’s Market Share leverages a Calendarized earnings approach.  We ensure included revenues are reflected from January to December for all vendors. Individual vendor corporate filing dates are translated to Calendarized earnings. 

No, revenue will only be provided by the market. Because Gartner’s published market share vendor revenue reflects Gartner’s estimates in all cases, the data does not intend to align with GAAP reported revenue, even for public companies.

Yes, when regional level data is available. However, certain markets, such as Enterprise Network Equipment, are only tracked at a worldwide level and will not have regional splits. Also, in cases where new markets are incorporated into MSM, their initial publication may include worldwide only totals – which may or may not incorporate more detailed regional splits in future publications.

No, Market Share Momentum as a publication will not evaluate vendor actuals. However, Gartner analysts may leverage the MSM data as a foundation to evaluate actuals and market shifts in future research.

MSM is a single, central publication serving as a light wrapper which provides a tabular data set. Evolving market dynamics are best addressed in Gartner's Forecast Analysis publications and other market-aligned research.
