Nvidia And 2 AI Infrastructure Stocks With Fast Growth And High Insider Ownership

With services sectors in the US and Eurozone showing stronger growth through recent PMI readings, investors are seeing fresh interest in companies that can turn this resilience into earnings momentum. Fast growing stocks with high insider ownership can be especially interesting when management teams are aligned with shareholders. This article highlights three stocks from that screener that merit a closer look right now.

The three stocks below are just a small sample, and the full screen surfaces 1,310 more fast growing companies with high insider ownership and equally compelling stories that are not covered here. To identify and analyze the ideas that best fit your own criteria, head straight into the Fast Growing Stocks With High Insider Ownership screener.

IREN (IREN)

Overview: IREN is a Sydney based company that owns and operates vertically integrated data centers and computing hardware in Australia and Canada, using that infrastructure to mine Bitcoin as its core growth facing business while also offering colocation and infrastructure services. The Bitcoin mining operation is the clearest link to the fast growing, insider backed theme, with the data center and services activity providing additional, but more diversified, revenue sources.

Operations: IREN currently generates most of its reported revenue in Australia at about $691 million, with around $65 million coming from Canada.

Market Cap: $15.2b

Investors looking at IREN today are not just getting exposure to a large scale Bitcoin miner that owns its data centers and power infrastructure; they are also seeing a business that is now plugged directly into the AI data center boom through multi year contracts with heavyweight customers such as Microsoft and Nvidia. A long runway of earnings and revenue growth forecasts above 20% a year lines up with that story, but it comes with important caveats that include heavy use of external funding, past dilution and a very rich P/E multiple. For investors who can handle volatility, the combination of contracted AI cloud revenue and high growth expectations makes IREN a stock worth understanding in more detail.

IREN’s AI data center contracts and Bitcoin exposure point to powerful momentum, yet the real story sits in the growth assumptions reflected in today’s rich P/E. Get the full context in the analyst forecasts for IREN

Nebius Group (NBIS)

Overview: Nebius Group is a technology company focused on full stack AI infrastructure, offering large scale GPU clusters, cloud platforms, and tools for developers, with additional exposure to edtech through TripleTen and autonomous driving technology through Avride. Its AI cloud business, supported by an alliance with Nvidia, is the clearest link to the fast growing, insider backed screener theme, even though the company also runs these other segments.

Operations: Nebius Group generates most of its revenue from the Nebius AI Cloud segment at about $1.3b, with smaller contributions from TripleTen at about $53 million and Avride at about $3 million, partly offset by $10 million of eliminations.

Market Cap: $60.3b

For investors following the Fast Growing Stocks With High Insider Ownership theme, Nebius Group offers a full stack AI cloud business backed by large GPU clusters, a deep Nvidia partnership, and multi billion dollar customer contracts that support recurring revenue and capacity buildout. Q2 2026 results showed very strong AI cloud momentum and a large backlog, yet profit margins remain thin at 3.1% and recent earnings fell sharply, reflecting heavy capital spending and pricing pressure in a crowded AI infrastructure market. Significant insider selling, high non cash earnings, and sizeable convertible debt issues also add funding and dilution risk. Investors considering direct exposure to large scale AI compute may want to research Nebius further and assess whether its risk profile fits their objectives and tolerance for volatility.

Nebius Group’s accelerating AI cloud scale and Nvidia partnership can look like the whole story, yet the real signal sits in the 1 key reward and 4 important warning signs (2 are major!) that could reshape how you think about its contracts and capital spend

Klarna Group (KLAR)

Overview: Klarna Group is a digital bank and flexible payments provider best known for its pay now, pay later and fair financing products that let consumers split purchases over weeks or up to 48 months. These buy now, pay later tools, combined with Klarna’s app, merchant integrations and membership programs, are the main connection to the fast growing consumer fintech theme. Its advertising and banking services add extra, but less central, revenue streams.

Operations: Klarna Group generates about $4.0b of revenue from its Data Processing segment, with most sales coming from the United States at about $1.5b, followed by Germany at about $921 million, other countries at about $1.1b and the United Kingdom at about $479 million.

Market Cap: $5.3b

Investors looking at Klarna Group today are seeing a BNPL focused fintech that is still unprofitable but is forecast for rapid earnings growth of about 55.5% a year, supported by expected revenue growth of around 14.1% and an expanding ecosystem of fair financing, memberships and card products. Recent Q2 results with a $9 million profit, 27% revenue growth to $1.04b and strong U.S. traction indicate the model can generate better margins. At the same time, lowered 2026 GMV and revenue guidance and heavy reliance on external borrowing keep risk firmly on the table. With the stock trading on a P/S near 1.3x versus higher peer averages, Klarna presents a combination of growth optimism, funding and competition risk, and potential valuation upside that may warrant closer scrutiny.

Accelerating BNPL growth, a P/S near 1.3x and fresh profitability make Klarna Group hard to ignore. Get the full story in the analyst forecasts for Klarna Group and see what the current forecasts might be missing.
