In 2025, Apple undertook its largest investment initiative to date, announcing a commitment to spend over $500 billion in the United States over the following four years, including the opening of a new manufacturing facility in Houston to produce servers supporting Apple Intelligence, expansion of research and development in fields like silicon engineering and AI, and the establishment of a new advanced manufacturing academy in Detroit. The company also pledged to double its US Advanced Manufacturing Fund and increase collaboration with American suppliers, aiming to create tens of thousands of jobs related to R&D, AI, and manufacturing technologies. The software landscape at Apple underwent a transformation in 2025, with Apple introducing the new Liquid Glass design language, rolling out unified system design updates across iOS 26, iPadOS 26, macOS Tahoe, and other platforms, and significantly expanding the capabilities of Apple Intelligence, the company's personal AI system, to address previous criticisms of fragmented interfaces, and use on-device and cloud-based AI to improve privacy and user experience. Despite continued growth in its services sector, including a new all-time high for services revenue in the March quarter and the launch of updated models such as the iPhone 16e and M4 MacBook Air, Apple faced significant challenges, contending with a 19% decline in stock value year-to-date, ongoing antitrust investigations by the US Department of Justice, and legal disputes involving the App Store. Competition in the AI space escalated, with rivals gaining ground, and high-profile departures and political tensions, including calls for Apple to manufacture iPhones domestically or face tariffs, added to the pressure, making 2025 one of the most challenging years for CEO Tim Cook. In December 2025, Cook met with US House members to push back against the App Store Accountability Act which could require that Apple authenticates users' ages and possibly collect sensitive data on children. On the 12th of January 2026, Apple announced a partnership with Google Gemini for AI-powered Siri, and in January 2026, Apple acquired Q.ai, an Israeli artificial intelligence startup specializing in imaging and machine learning technologies for audio processing, with the financial terms not disclosed, though media reports estimated the acquisition at nearly US$2 billion, Apple's second-largest purchase to date, and following the deal, Q.ai's founders and approximately 100 employees joined Apple. As of 2023, there are over 2 billion Apple devices in active use worldwide, and in February 2023, that number exceeded 2 billion devices. In 2023, the World Intellectual Property Organization's Madrid Yearly Review ranked Apple's number of trademark applications, filled under the Madrid System, as 10th in the world, with 74 trademark applications submitted during 2023, and Apple was ranked the No. 3 company in the world in the 2024 Fortune 500 list. Apple's product lineup includes portable and home hardware like the iPhone, iPad, Apple Watch, Mac, and Apple TV, several in-house operating systems such as iOS, iPadOS, and macOS, and various software and services including Apple Pay and iCloud, as well as multimedia streaming services like Apple Music and Apple TV. Since 2011, Apple has for the most part been the world's largest company by market capitalization, and, as of 2025, is valued at just over $4 trillion, making it the largest manufacturing company by revenue, the fourth-largest personal computer vendor, the largest vendor of tablet computers, and the largest vendor of mobile phones. Apple has received criticism regarding its contractors' labor conditions, its relationship with trade unions, its environmental practices, and its corporate ethics, including anti-competitive tactics, materials sourcing, and its acquisitions of smaller businesses, but nevertheless, the company has a large following and enjoys a high level of customer loyalty, and has consistently been ranked as one of the world's most valuable brands since the late 2000s.
