Cisco Systems Inc.
Cisco Systems has been benefiting from strong product orders from hyperscalers, enterprises, service providers, the public sector and cloud customers. In the last reported quarter, CSCO generated record-high revenues primarily due to its networking portfolio, powered by Silicon One, AI-native security solutions and operating systems.
CSCO expects total AI infrastructure orders to reach $9 billion in fiscal 2026, an increase of 4.5X from fiscal 2025. Overall product orders grew by a sizable 35% year over year in the third quarter. Of this, data center switching orders grew 40% from the year-ago period, supported by massive AI-powered data center buildout.

The platform's comprehensive observability and security suite addresses critical enterprise needs for cloud infrastructure monitoring, application performance management, security analytics, LLM observability, data observability and cloud cost management in increasingly hybrid, multi-cloud and AI-driven environments. Enterprise customers typically deploy multiple Datadog products, creating significant expansion opportunities through cross-selling and upselling.
DDOG’s leadership in AI-powered observability and security establishes significant competitive advantages as enterprises increasingly prioritize intelligent monitoring solutions.

Palantir Technologies Inc.
Palantir Technologies’ AI strategy is comprehensive, combining its proprietary Foundry and Gotham platforms with a solid plan to promote AI adoption across both government and commercial sectors. PLTR’s AI Platform (AIP) is the backbone of these capabilities, enabling organizations to process large datasets and derive real-time insights. This is especially valuable in sectors requiring extensive data integration, such as defense, healthcare, finance and intelligence, where operational efficiency and decision-making speed are critical.
In the government sector, Palantir is aligning its AI strategy with U.S. defense priorities. Its work in high-profile initiatives, such as the Department of Defense’s Open DAGIR project, highlights its ability to modernize military operations through AI-driven solutions where data interoperability and real-time decision-making capabilities are imperative. These capabilities solidify PLTR’s position as a key player in the defense sector.
In the commercial space, Palantir’s AIP boot camps — providing hands-on experience to over 1,000 companies — have proven instrumental in customer acquisition. Boot camps showcase the platform’s capabilities and demonstrate its adaptability across logistics, manufacturing, and supply-chain management. PLTR’s core customer base comprises businesses seeking tailored AI/ML services, particularly large government and corporate clients willing to invest heavily in its systems.
Palantir has an expected revenue and earnings growth rate of 71.8% and 98.7%, respectively, for the current year. The Zacks Consensus Estimate for the current year’s earnings has improved 11.2% over the last 30 days.
