Artificial intelligence stocks sit at the crossroads of several forces that investors are watching in 2026. Global growth signals are mixed, central banks continue to weigh inflation data, and energy costs remain a key swing factor. At the same time, demand for AI related chips, software, cloud and large language models links into real investment and trade flows across the US, Europe and Asia. This article uses an AI Stocks screener focused on companies directly involved in the ChatGPT and broader AI transformation. It will highlight 3 of the most interesting stocks from that screener for your watchlist.

RingCentral (RNG)

Overview: RingCentral is a US based provider of cloud communication tools that use agentic voice AI to handle business phone calls, SMS, video meetings and contact center workloads on one platform for customers ranging from small firms to large enterprises across sectors such as healthcare, finance, retail and government.

Operations: RingCentral generates about US$2.58b from Internet Software & Services, reflecting its focus on cloud based communication and contact center solutions.

Market Cap: US$4.75b

RingCentral provides exposure to the shift toward AI powered customer communications, with products like RingCX and AI Receptionist operating within a platform that already serves a broad base of business users. The company combines this with tighter cost control, rising profitability and capital returns through buybacks and a higher dividend. These factors can matter for investors who view the stock as trading below estimated fair value based on analyst assessments. The risk side is also significant. High debt, negative equity, intense competition from bundled suites such as Microsoft Teams and recent insider selling all raise questions about how durable the story is. Taken together, these elements help explain why some investors are paying close attention to RingCentral at the moment.

RingCentral’s rising profitability and capital returns could be masking a deeper story around its AI push and balance sheet pressure. Before you decide where it fits on your watchlist, unpack the 3 key rewards and 4 important warning signs (1 is major!)

Nebius Group (NBIS)

Overview: Nebius Group builds full stack AI infrastructure, providing large scale GPU clusters, cloud platforms and developer tools, alongside its TripleTen tech education platform and Avride autonomous driving technology, for customers across the US, UK and other international markets.

Operations: Nebius Group generates most of its US$878.9m in revenue from its Nebius AI infrastructure platform at US$828.6m, with smaller contributions from TripleTen at US$55.2m, Avride at US$2m and eliminations of US$7.9m.

Market Cap: US$37.94b

Nebius Group provides direct exposure to the build out of AI compute, combining full stack infrastructure, Nvidia backed financing and long term contracts such as the reported multi year Reflection AI deal and major hyperscaler partnerships. At the same time, heavy capital needs, a high valuation, reliance on large customers like Meta and Microsoft, and sector wide volatility mean the stock carries meaningful execution and concentration risk. Questions around brand strength outside core regions and the move toward an asset light model are also important for assessing the durability of future margins and returns. If you want to see how these growth drivers and pressure points fit together into a single picture, the 2 key rewards and 3 important warning signs (2 are major!)

Nebius Group’s full stack AI story looks powerful; however, the real tension sits between capital intensity, big ticket contracts and concentration risk. See how that balance plays out in the 2 key rewards and 3 important warning signs (2 are major!)

Klaviyo (KVYO)

Overview: Klaviyo is a Boston based software company that helps consumer facing businesses run email, SMS, social and customer service in one cloud platform, using AI tools to design campaigns, talk to customers and analyze what is driving sales in real time.

Operations: Klaviyo generates about US$1.31b in revenue from Internet Software, with sales spread across the United States, Europe, the Asia Pacific region and other international markets.

Market Cap: US$5.65b

Klaviyo offers focused exposure to AI driven marketing and customer service, with products like its AI Marketing Agent, Customer Agent and new Social Marketing tools feeding into a single data rich B2C CRM platform. Revenue is growing, guidance for 2026 was raised, and recent results moved the company from a loss to a profit. However, the stock still trades well below some analyst fair value estimates. The flip side is important: margins are under pressure from messaging costs, the business is still building its track record at scale, and competition from large cloud suites is intense. Understanding how these growth drivers and risks fit together is crucial if you are weighing Klaviyo against other AI stocks.

Klaviyo’s shift from losses to profit with AI at the core of its marketing engine could be only half the story. See how the analyst forecasts for Klaviyo reshapes expectations around what comes next
