Competition cases ask courts to understand how markets really work: who competes with whom, how customers choose, how prices and terms are set, and how businesses respond to rivals. Antitrust expert witnesses supply that understanding, and the top antitrust expert witnesses pair rigorous analysis with clear explanation. Economists who are top antitrust expert witnesses typically lead on market definition and competitive effects, while industry experts such as Scott Steinberg provide the real-world context about sample areas like AI, technology platforms, app stores, online marketplaces, video games, digital media, and consumer technology that grounds the economic analysis.

Technology markets have become a major focus of competition litigation. App store policies, platform rules, exclusive deals, bundling of digital services, acquisitions of fast-growing startups, and pricing for digital content all raise competition questions. These markets move quickly and operate in ways that differ from older industries, which makes industry expertise especially valuable.

This guide explains how industry experts fit into the antitrust expert team and how their market knowledge supports economic analysis in technology and gaming cases.

The Antitrust Expert Team

Economic experts analyze market definition, market power, competitive effects, and damages using economic theory and data.

Industry experts explain how a market operates in practice: business models, customer behavior, product development, distribution channels, partnerships, and the history of competition.

Technical experts describe how products and platforms function where technology is central to the claims.

Damages experts quantify financial harm, often in coordination with economic and industry experts.

Each expert addresses different questions, and their work is most persuasive when it fits together into a consistent account of the market.

How Industry Experts Contribute

Describing How the Market Works

Industry experts explain who the participants are, how products reach customers, how companies make money, and how relationships among platforms, developers, publishers, and consumers are structured.

Customer Choice and Substitution

Courts often need to understand which products customers consider interchangeable. Industry experts describe how consumers and businesses actually shop, switch, and compare options, providing context for economic analysis of market boundaries.

Business Practices and Their Rationale

Platform rules, exclusive agreements, and bundled offerings may have competitive explanations, such as quality control, security, or efficiency, as well as potential competitive concerns. Industry experts describe common practices and the business reasons companies typically give for them.

Market History and Entry

Experts explain how a market developed, which companies entered and exited, how innovation changed competition, and what barriers or opportunities new entrants faced.

Antitrust Issues in Gaming and App Stores

Video game and app markets have generated significant competition questions. Issues may include storefront commission rates, rules on in-app payments, exclusivity arrangements for games or content, console platform policies, subscription services, cloud gaming, and acquisitions of studios and publishers. Industry experts with gaming and app store knowledge can explain how developers distribute games, how players discover and purchase them, how platform holders and publishers negotiate, and how business models have shifted over time.

Platform Markets and Network Effects

Many technology markets involve platforms that connect different groups: app stores connect developers and users, game consoles connect publishers and players, marketplaces connect sellers and buyers, and social networks connect users and advertisers. These platforms often benefit from network effects, where each additional participant makes the platform more valuable to others.

Platform markets raise distinctive questions in competition cases. How should a market be defined when a platform serves two sides at once? How do fees on one side affect participation on the other? How easily can users or developers move to alternatives? Industry experts help courts understand how these platforms actually work, how participants on each side behave, and how platforms have evolved, giving economic experts a solid factual foundation.

Acquisitions in Technology and Gaming

Acquisitions of startups, studios, and technology companies can draw scrutiny from regulators and competitors. Questions may include whether a deal removes a potential competitor, whether the merged company could restrict access to important products, or whether the acquisition brings efficiencies that benefit consumers. Industry experts explain the strategic rationale for such deals, how similar acquisitions have played out in the industry, how content and technology are typically licensed across platforms, and how competitors and customers are likely to respond.

Pricing, Commissions, and Business Models

Digital markets use many pricing approaches: commissions on transactions, subscriptions, free products supported by advertising, freemium models, bundled services, and variable pricing. In competition disputes, courts often need to understand why companies adopt particular models and how those models affect developers, partners, and consumers. Industry experts explain the history and rationale of pricing structures in the relevant market and how participants typically respond to changes.

Documents, Testimony, and Market Reality

Antitrust cases often involve vast document productions, internal strategy presentations, and executive testimony. Industry experts help counsel interpret these materials in context, explaining industry terminology, common strategic language, and how internal documents typically reflect competitive planning. This interpretation helps courts read routine business language accurately and focus on the evidence that matters most.

Exclusive Deals and Content Access

Exclusive arrangements are common in technology and entertainment. A console maker may secure a game that launches only on its platform. A streaming service may license content exclusively. An app may partner with a single payment provider. These deals can bring investment, marketing support, and better products, and they can also raise questions about access for rivals.

Industry experts explain why companies pursue exclusives, how such deals are typically negotiated, how long they usually last, and how customers and competitors respond. They provide the factual context economists need to evaluate whether a particular arrangement is likely to help or hinder competition in the market at issue.

Developers, Creators, and Small Businesses

Many technology antitrust cases involve the businesses that depend on large platforms: app developers, game studios, online sellers, and content creators. These businesses may challenge platform fees, ranking rules, data access, or policy changes. Industry experts describe how such businesses operate, how much they rely on particular platforms, what alternatives exist, and how platform decisions affect their costs and customer reach. This perspective helps courts understand the practical stakes for businesses on each side of the platform.

How Antitrust Cases Use Industry Testimony Over Time

Antitrust matters often run for years and involve multiple phases. Early on, industry experts help counsel understand the market and frame the issues. During discovery, they help identify the documents, data, and witnesses that will matter. In expert reports, they describe market structure, industry history, and business practices, providing a foundation for economic analysis. At class certification in private actions, they may describe how pricing and terms applied across groups of customers. At trial, they help judges and juries understand the market in concrete, relatable terms.

Consumer Perspective in Technology Markets

Consumer behavior often decides how a market is defined. Do players view mobile games and console games as substitutes? Would app users switch platforms if fees rose? How attached are customers to the ecosystems they have invested in, with their purchased content, saved progress, and connected devices? Industry experts draw on market research, usage patterns, and years of observing the industry to describe how consumers choose and switch, giving economic analysis a grounded starting point.

Illustrative Antitrust Scenarios

The App Store Fee Challenge

A group of developers challenges a platform’s commission on digital sales and its rules on alternative payment options. An industry expert can describe how developers distribute and monetize apps, how payment rules affect their businesses, what alternatives exist, and how commission structures developed across digital storefronts.

The Console Exclusive

A competitor argues that exclusive deals for major game releases limit its ability to attract players. Industry experts explain how exclusives are negotiated, how players choose platforms, how often games eventually arrive on other systems, and how exclusives affect investment in new titles.

The Startup Acquisition

Regulators question whether a large platform’s purchase of a promising startup removes a future competitor. Industry experts describe the startup’s product, its growth trajectory, the competitive options available to users, and how similar acquisitions have influenced the market.

Explaining Markets to Juries

Antitrust trials can involve abstract concepts like market definition, substitution, and network effects. Industry experts make these ideas concrete. They describe how a developer decides where to launch a game, how a consumer picks a smartphone, or how a seller chooses which marketplace to list on. These stories help jurors understand the economic analysis and see how the conduct at issue affects real businesses and people.

Market Changes Over Time

Technology markets change quickly. A dominant product today may face formidable challengers tomorrow, and new business models can upend established players. Industry experts provide a timeline of market developments, helping courts evaluate conduct in light of conditions at the relevant time and understand how competition has evolved.

Preparing an Industry Expert for an Antitrust Matter

Counsel can support their industry expert by sharing pleadings, key strategy documents, market research, pricing histories, and testimony from industry witnesses. Access to the economic expert’s framework helps the industry expert focus on the factual questions that matter most to the analysis. Regular coordination among counsel, economists, and industry experts keeps the presentation consistent, and early engagement allows the industry expert to help identify the documents and data that best illustrate how the market works.

Consumers, Prices, and Quality

Competition affects more than prices. In technology markets, rivalry also drives innovation, product quality, privacy features, and choice. Industry experts help courts appreciate these dimensions by describing how products have improved over time, how companies compete on features and experience, and how consumers weigh factors beyond price when choosing platforms, games, and services.

Independence Across the Market

Antitrust disputes often involve the largest companies in an industry. Industry experts who have worked with platforms, developers, publishers, and consumers bring a rounded perspective and can describe market realities from several vantage points. That balance strengthens their credibility and helps courts trust their account of how the market operates.
