The SpaceX IPO has pulled fresh attention to mega cap technology, with investors reassessing which giants might gain or lose as money shifts around the sector.

This article looks at three Mega Cap Technology Leaders that are closely tied to the current buzz, and breaks down how the recent news may affect each stock so you can decide whether they deserve a closer look or a wider berth.

ServiceNow (NOW)

Overview: ServiceNow runs a cloud platform that helps large organisations automate and connect their IT, customer service, HR, security and other workflows, so work moves through a single system rather than across disconnected tools and emails. Its software and AI tools are used across sectors like government, finance, healthcare and technology to manage tickets, approvals, assets and data at scale.

Operations: ServiceNow generates about US$14.0b in revenue from internet software and services, with roughly US$8.3b from the United States and the rest mainly from EMEA at about US$3.6b and Asia Pacific and other regions at about US$1.6b.

Market Cap: US$106.3b

ServiceNow sits right in the cross section of two big themes investors care about today: workflow automation and enterprise AI. The SpaceX driven enthusiasm for mega cap tech only adds attention to stocks like this. The company already produces billions in free cash flow from highly recurring subscriptions and is pushing deeper into AI agents, data fabric and governance through partnerships with players like IBM, NVIDIA and major cloud providers. At the same time, the stock carries a rich valuation, insider selling has picked up and funding is described as higher risk, so execution and AI monetisation really matter. If you are trying to separate durable compounders from the rest of the AI crowd, ServiceNow is a business that deserves a closer look.

ServiceNow’s AI push and rich valuation make a powerful mix, but the real story is how much is already priced in versus what its workflow platform could still become, according to the 3 key rewards and 1 important warning sign

Oracle (ORCL)

Overview: Oracle provides cloud infrastructure, databases, and business software that help companies, governments, and hospitals run core functions such as finance, HR, supply chains, customer service, and healthcare systems, often on a single integrated stack.

Operations: Oracle generates about US$34.0b from Cloud services, US$24.5b from Software, US$5.7b from Services, and US$3.1b from Hardware, with most revenue coming from the Americas, followed by Europe, the Middle East and Africa, and Asia Pacific.

Market Cap: US$529.5b

Oracle sits at the heart of the current AI build out, supplying cloud infrastructure and databases for heavyweight customers like OpenAI while carrying a very large backlog of contracted work that gives visibility into future demand. Analysts are watching how its premium P/E, high margins, and rising dividend compare with concerns around heavy data center capex, high debt, and potential dilution from planned funding. With recent enthusiasm around mega cap technology companies and Oracle positioned as an AI infrastructure partner, the key question is whether the market is fully appreciating the trade off between its growth pipeline and the risks tied to financing that expansion.

Oracle’s AI cloud story is accelerating, but the real tension sits between its premium P/E, heavy data center spend and sizeable debt load. Get the full picture in the 3 key rewards and 2 important warning signs (1 is major!)

CrowdStrike Holdings (CRWD)

Overview: CrowdStrike provides cloud based cybersecurity software that protects laptops, servers, cloud workloads, identities and data, sold as subscriptions on its Falcon platform. It helps customers spot and stop attacks in real time, increasingly using AI tools and automation so security teams can respond faster with fewer manual tasks.

Operations: CrowdStrike generates about US$5.1b from Security Software and Services, with around US$3.4b from the United States and roughly US$1.7b from Europe, the Middle East and Africa, Asia Pacific and other regions combined.

Market Cap: US$176.0b

CrowdStrike sits at the intersection of interest in mega cap tech, AI and security, which helps explain why it often trades on lofty expectations and why the SpaceX and AI enthusiasm wave is pulling fresh attention toward it. The Falcon platform now spans 33 products and is used to secure AI workloads as well as traditional endpoints, with offerings like Falcon Flex and AI assistants designed to deepen customer commitment and expand contract spend. At the same time, the stock carries a very high P/S multiple, insider selling has been significant and the company is only expected to reach profitability within the next few years. Investors therefore need to balance the potential impact of these growth drivers with a rich price tag and tight expectations that leave little room for disappointment.
