AI is no longer just about the mega caps at the top of every headline. With central banks reacting to inflation, oil prices swinging on Middle East tensions, and trade patterns shifting from China to Europe and beyond, smaller AI focused stocks are where early product ideas, niche data tools, and automation platforms are being built. This AI Small Caps screener is designed to filter for those under the radar opportunities that sit inside these global cross currents. In this article, you will see 3 stocks from the screener that stand out for further research.

Pagaya Technologies (PGY)

Overview: Pagaya Technologies runs an AI driven platform that helps banks, fintechs, auto lenders and real estate partners assess loan applications, approve more customers and package those loans into asset backed securities for institutional investors, using its data network and tools such as Decline Monetization, Dual Look and First Look.

Market Cap: US$1.22b

Pagaya is interesting if you are looking at how AI is reshaping credit decisions and securitization, with a platform already used across personal loans, auto finance and point of sale partners like Sezzle. The company is profitable on a GAAP basis, has raised full year 2026 guidance and is growing its ABS issuance. At the same time, it trades on a P/E that is described as well below both its estimated fair value and many software peers. Set against that, investors need to weigh a recent US$140.2m one off loss, share price volatility and a funding model that relies entirely on external borrowing. This makes a deeper look at its cash flows, ABS program and partner concentration important before deciding how it fits in a portfolio.

Pagaya’s profitable GAAP earnings and low P/E against peers raise a clear question: is the market underpricing its AI credit engine, or correctly factoring in that US$140.2m one off loss and funding risk revealed in the 4 key rewards and 2 important warning signs?

SoundHound AI (SOUN)

Overview: SoundHound AI builds voice and conversational AI systems that let cars, call centers, restaurants, devices and apps understand natural speech, answer questions and handle customer requests across multiple languages and use cases.

Operations: SoundHound AI currently generates about US$168.9m in annual revenue from Internet Software & Services, with sales spread across the United States, Korea, France, Germany and other international markets.

Market Cap: US$4.0b

SoundHound AI may be worth a closer look for investors seeking exposure to voice and agentic AI that is already embedded in real world use cases, from cars and restaurants to customer service. Its partnerships, acquisitions and products such as OASYS and the planned LivePerson deal reflect an ambition to provide end to end conversational experiences. Revenue of US$168.9m in 2025 and guidance of US$225m to US$260m for 2026 are reported alongside ongoing losses, high P/S multiples and heavy reliance on external funding, as well as recent insider selling and substantial stock based compensation that add dilution risk. A key consideration for investors is whether this expanding platform, patent base and enterprise pipeline justify the current valuation and cash usage, or whether the risks around profitability and capital structure are more significant.

SoundHound AI’s expanding voice and agent platform, rising revenue targets, and heavy funding needs create a tension that many investors may be glossing over. Put the full story in context with the 1 key reward and 4 important warning signs (1 is major!)

Ambarella (AMBA)

Overview: Ambarella develops low power AI system on chips and software that help cameras, cars, and connected devices see, understand, and react to the physical world in real time, supporting uses from driver assistance and telematics to security, robotics, and video conferencing.

Operations: Ambarella generates all of its US$390.7m in revenue from semiconductors, with sales concentrated in Taiwan at US$271.9m and the rest spread across other Asia Pacific markets, Europe, North America, and the United States.

Market Cap: US$3.31b

Ambarella sits at the intersection of edge AI and computer vision, with a unified software platform and CVflow chips that are already in security cameras, automotive systems, and a growing set of physical AI devices. Revenue of US$390.7m provides evidence of current scale, while recognition from the IEEE for its CEO and upcoming events such as Embedded World 2026 highlight a technology story that is resonating with developers and partners. At the same time, the company is still loss making, heavily exposed to cyclical IoT demand and relies on a concentrated set of customers. Investors may wish to weigh whether its expanding AI design wins and buyback activity can offset these risks and support the current valuation.

Ambarella’s edge AI story, real world revenue of US$390.7m and ongoing losses raise a bigger question: the 2 key rewards and 2 important warning signs could reveal what the market might be missing right now
