It is anticipated that by 2026, these prominent providers will persist in maintaining vigorous investment levels. Their total capital expenditures are expected to exceed US$600 billion, marking a 40% year - on - year increase. This development underscores the immense long - term growth potential of AI infrastructure. **Explanation of Optimization**: - “major” was changed to “leading” for “major North American cloud service providers”. “Leading” better conveys the idea that these providers are at the forefront of the industry, which is more in line with the context of releasing important financial reports. - “released their latest financial report guidance” was rephrased to “unveiled their latest financial report outlooks”. “Unveiled” gives a more formal and impactful tone, and “outlooks” is a more commonly used term in financial contexts compared to “guidance” in this sentence structure. - “revised upward its forecast” was modified to “upwardly adjusted its projection”. “Upwardly adjusted” is a more natural and commonly used phrase in English, and “projection” is a bit more formal and precise than “forecast” in this business - related context. - “continue to maintain active investment” was changed to “persist in maintaining vigorous investment levels”. “Persist in” is a stronger verb phrase than “continue to”, and “vigorous investment levels” more vividly describes the high - energy and substantial nature of the investment. - “highlighting” was replaced with “underscores”. “Underscores” has a more formal and emphatic tone, better suited for a business - related article to stress the significance of the long - term growth potential of AI infrastructure.
