Artificial intelligence (AI) within the consumer, enterprise, government, and defense sectors is no longer considered a technology that is “nice to have.” Tractica believes the global market has entered a new era where AI is viewed as an essential technology to driving improvements in quality, efficiency, and speed. In some industries, such as consumer services and telecommunications, AI has already become commonplace. Numerous vendors have established client rosters with both Fortune 500 bellwethers and nimble upstarts. Although the market is still nascent and significant work remains to be done before AI becomes a mainstream technology, end users and solutions providers must identify the technologies and use cases where they want to invest in AI. Tractica has built a taxonomy of more than 330 AI use cases across 28 industry sectors that captures the business-to-business (B2B) software opportunity related to AI. The use cases cover three major meta categories: vision, language, and analytics. Analytics is a major driver for AI and is a continuation of business analytics and classical machine learning (ML) techniques. However, according to Tractica’s analysis, deep learning (DL)-based human perception derived from vision and language is a bigger driver for AI in the long run. Annual global AI software revenue is forecast to grow from $10.1 billion in 2018 to $126.0 billion by 2025. This Tractica report provides a quantitative assessment of the market opportunity for AI across the consumer, enterprise, government, and defense sectors. The study includes market sizing, segmentation, and forecasts for 333 AI use cases, including more than 200 unique use cases. Tractica has added use cases spread across multiple industries, including energy, manufacturing, retail, consumer, transportation, public sector, media and entertainment, telecommunications, and financial services. We have also removed or combined use cases to better reflect the current and future AI market landscape. Global market forecasts, segmented by use case, technology, geography, revenue type, and meta category, extend through 2025.
