Butterfly Network And 2 Other AI Stocks To Watch

Simply Wall St · 1d ago

US GDP just grew at a 3.4% annual rate, helped by a surge in AI related investment, which tells you where serious capital is flowing today. Large platforms are spending heavily to build the infrastructure. That spending can feed into smaller AI focused businesses working on machine learning, automation and data tools. This article highlights three such small cap stocks that sit on that theme and warrant closer examination.

The three small cap examples covered below are only a sample of what is available in this corner of the market, and the full screen surfaced 33 more AI focused companies with equally compelling business stories that are not covered here. If you want to zero in on the AI stocks that best fit your own risk profile and time horizon, head straight into the AI Small Caps screener to identify, compare, and analyze the highest conviction opportunities.

Butterfly Network (BFLY)

Overview: Butterfly Network develops handheld ultrasound devices and AI-powered software like Compass AI and ScanLab that connect imaging, workflows, and real-time guidance across healthcare settings.

Operations: Butterfly Network generates about US$112 million from its AI-enhanced personal ultrasound solution, with roughly US$92 million from the United States and US$20 million internationally.

Market Cap: US$2.0b

Butterfly Network matters for the AI Small Caps theme because its handheld scanners are increasingly tied to software intelligence, not just hardware units. This is where the potential long-term leverage sits for early-stage medical imaging platforms.

"Midjourney’s partnership reflects growing industry interest in Butterfly’s ultrasound-on-chip innovation, coinciding with the company's launch of Compass AI, its latest AI-powered enterprise software platform aimed at improving healthcare workflow, compliance, and revenue capture."

The real swing factor for Butterfly Network is what happens if one quiet assumption about future AI-led usage patterns in healthcare shifts meaningfully.

If that usage pattern really shifts, you will want the full narrative for Butterfly Network that maps how Butterfly Network’s AI, pricing power and adoption could evolve from here.

SoundHound AI (SOUN)

Overview: SoundHound AI builds voice assistants and conversational AI tools that power hands-free interactions across cars, devices, restaurants, and customer service.

Operations: SoundHound AI generates about US$203 million from internet software and services, with roughly US$136 million from the United States and US$46 million elsewhere.

Market Cap: US$2.0b

SoundHound AI matters for the AI Small Caps theme because Houndify and SoundHound Chat AI push voice interfaces into everyday settings, from car dashboards to drive-thru lanes, where conversational agents can quietly become the default way people interact with technology.

"Accelerating global adoption of voice-enabled and AI-powered interfaces across new and existing verticals, including automotive, enterprise, restaurants, and healthcare, continues to drive expansion of SoundHound AI's addressable market, supporting sustained double and triple digit year over year revenue growth and improved customer diversification."

The real test for SoundHound AI now is how one unresolved cost and funding pressure shapes the journey from rapid rollout to durable margins.

That funding question is exactly what the full narrative for SoundHound AI unpacks. It ties SoundHound AI's rollout pace to contract quality, cash runway, and where upside could still be underestimated.

Operations: Penguin Solutions generates about US$1.7b in revenue, with US$558.8 million from Advanced Computing, US$924 million from Integrated Memory, and US$248.7 million from Optimized LED.

Market Cap: US$3.6b

Penguin Solutions gives this AI Small Caps screen exposure to the less flashy but essential plumbing behind AI. Full-stack infrastructure and memory capacity quietly determine how far training and inference workloads can actually scale.

"Increasing demand for scalable and energy-efficient data center solutions, driven by edge computing and new AI workloads, aligns with Penguin's differentiated, customizable hardware and software offerings, supporting higher-margin solution sales and long-term improvement in net margins."

The real tension for Penguin Solutions now lies in how one emerging pressure on profitability shapes the payoff from all that AI infrastructure demand.

That pressure point is exactly where the full narrative for Penguin Solutions shows how Penguin Solutions could convert AI demand into accelerating cash generation while masking key risks in the current headline story.
