Top 3 Performing AI Stocks Over the Past 4 Weeks

May 22, 2025

The AI sector continues to chart new territory, and this week, we look at top three companies that have demonstrated exceptional stock price performance over the last four weeks. Each is carving out a distinct niche in the AI ecosystem: Nebius (NBIS), an AI infrastructure powerhouse, up 59%; CoreWeave (CRWV), a specialised GPU cloud maverick, soaring an impressive 157%; and Evolv Technologies (EVLV), a pioneer in AI-driven physical security solutions, rising 67%.

Let’s start with the best performer over the past four weeks, CoreWeave.

1. CoreWeave CRWV — The Specialised GPU Cloud Maverick

CoreWeave has more than doubled since its IPO in March, partly because of strong financial results and also because Nvidia has a major stake in the company. It has carved out a significant niche by focusing intensely on GPU-accelerated cloud computing.

AI Angle: CoreWeave is central to AI development and deployment. Their expertise in securing and deploying the latest generation of GPUs, such as the highly sought-after H100s, provides a critical competitive advantage and positions them as a key partner for companies pushing the boundaries of AI.

Latest Updates: The company reported a staggering 420% revenue growth in the first quarter. Earnings per share met expectations, although near-term profitability remains impacted by strategic investments in expanding capacity — a common trait among hyper-growth firms. CoreWeave also announced significant new customer wins, particularly in the generative AI space.

2. Nebius NBIS — The AI Infrastructure Powerhouse

Nebius is rapidly emerging as a critical “picks and shovels” participant in the AI expansion. They specialise in providing high-performance cloud infrastructure specifically optimised for AI and machine learning workloads, designed to support the rigorous demands of training and deploying sophisticated AI models.

AI Angle: Nebius does not merely utilise AI; they enable it at scale. Their core business is to provide the raw compute power and scalable infrastructure that AI developers and large enterprises require for everything from Large Language Model (LLM) training to complex data analytics and generative AI applications.

Latest Updates: The company recorded $55 million in revenue for its March-ended quarter, representing a 385% year-over-year increase, driven by strong demand for AI-focused cloud services. Management emphasised rapid customer base expansion and raised full-year guidance, citing a robust pipeline and sustained high demand for AI compute capacity.

3. Evolv Technologies EVLV — The AI-Driven Security Innovator

Evolv Technologies specialises in AI-powered physical security solutions, providing advanced screening systems that improve safety while enhancing throughput at venues and public spaces.

AI Angle: Evolv’s platform leverages AI and sensor fusion to detect weapons and threats swiftly and accurately without impeding the flow of people. This integration of AI into security operations addresses growing demand for smarter, faster, and less intrusive security screening.

Latest Updates: The company has reported growing adoption of its AI-driven screening technology across industries including entertainment, transportation, and critical infrastructure. Recent earnings reflect steady quarterly revenue growth of 41.4%, supported by increased deployments and long-term contracts.

The AI Stock Tracker

To help distinguish notable movements within this dynamic sector, our in-house growth-weighted model scans 173 AI-linked names twice weekly. To earn Watchlist status, a stock must score of ≥ 70 (out of 100) and rank in the top 20 percent for momentum (RS ≥ 80).

Nebius (NBIS) shows strong momentum that aligns with its recent price surge, but it falls short on several key fundamental metrics. CoreWeave (CRWV) shows also strong momentum and growth, yet it narrowly misses the fundamentals threshold due to valuation concerns, which are common following rapid stock price increases. Similarly, Evolv Technologies exhibits solid momentum and growth but also falls just below the fundamentals threshold, primarily because of stretched valuation metrics.

As a result, none of these stocks qualify for our Watchlist at this time.

The AI landscape is evolving rapidly, with Nebius, CoreWeave, and Evolv Technologies each playing unique and influential roles within this broad and dynamic sector. Our AI Stock Tracker highlights that even the strongest performers differ significantly when evaluated through a comprehensive, multi-dimensional framework. While impressive recent gains catch the eye, a well-rounded assessment that balances growth, valuation, and momentum is vital for making informed decisions in the emerging world of AI-driven innovation.
