Best Small-Cap Fintech Stocks for 2026: Your Growth Guide

Imagine a digital brokerage that's rapidly expanding its reach across the globe, bringing investment opportunities to more people. That's UP Fintech Holding Limited (TIGR), often known for its Tiger Brokers platform. This company is making waves, especially in markets like Singapore and Hong Kong. In the first quarter of 2026, UP Fintech reported a solid 26.3% year-over-year increase in revenue, hitting $154.9 million. Their operating income also saw a healthy jump of 17.5% year-over-year, reaching $47.6 million. This growth isn't just about numbers; it's about more people engaging with financial markets. The company added 28,900 new funded accounts in Q1 2026, bringing their total to an impressive 1.28 million, an 11.3% increase from the previous year. What's more, their total trading volume surged by 49% year-over-year to a whopping $323.9 billion. While they did report a net loss of $26.9 million in Q1 2026, this was primarily due to a one-off regulatory penalty of approximately $59.7 million, which management believes won't materially impact their long-term development. Looking ahead, management expects their Q2 2026 US cash equity trading volume to match the first quarter's total, and anticipates a solid quarter-over-quarter increase in total client assets. They've even approved a $50 million share repurchase program, signaling confidence in their future. For investors interested in the global expansion of digital wealth management, TIGR offers an intriguing play.

Lending might sound traditional, but Upstart Holdings, Inc. (UPST) is anything but. This company is shaking up the lending world by using artificial intelligence (AI) to assess creditworthiness, aiming to provide more people with access to affordable credit. Instead of relying solely on traditional credit scores, Upstart's platform looks at a wider range of data points, which can be a game-changer for many borrowers. The company has been reiterating strong guidance for both fiscal year 2026 and 2028, pointing towards a multi-year path of profitable growth. In the first quarter of 2026, Upstart saw promising loan originations, and their automated originations reached 91%, which is a big deal for improving their profit margins. Their partners funded $15.33 billion in loans in Q1 2026, marking a significant 33.4% increase year-over-year. This growth in partner-funded loans is crucial as it means Upstart isn't holding too many loans on its own balance sheet, reducing risk. With a price-to-earnings (P/E) ratio of 14.95x and a 3-year PEG ratio of 0.40x, the stock looks compelling compared to historical levels and peers. While the company is set to report its Q2 2026 earnings on August 4, 2026, the management's outlook for fiscal year 2026 includes revenues from fees around $1.3 billion (a 23.5% year-over-year increase) and adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) margins of 21%, alongside positive net incomes. Upstart represents a fascinating opportunity in the evolving landscape of AI-driven financial services.

Payments are the backbone of the economy, and Repay Holdings (RPAY) focuses on making them smoother and more efficient, especially in specialized markets. Think about industries like automotive, healthcare, or legal services – they often have unique payment needs. Repay steps in with its integrated payment processing solutions, helping businesses accept payments more easily and securely. As of May 2026, Repay had a market capitalization of approximately $365 million, firmly placing it in the small-cap category. What makes Repay particularly interesting is its adjusted EBITDA-positive business model. EBITDA is a way to look at a company's profitability before accounting for things like interest payments, taxes, and the wear-and-tear on assets. Being EBITDA-positive means the core operations are generating cash, which is a strong sign of financial health. Their focus on specific vertical markets helps them build deep expertise and create 'switching costs,' meaning once a business integrates Repay's solutions, it's often more challenging and costly to switch to a competitor. This can lead to more stable, recurring revenue streams. While specific recent revenue or earnings figures for 2026 weren't broadly available in our search, the company's strategic positioning in niche payment processing, combined with its positive EBITDA, suggests a solid foundation for continued growth in the dynamic fintech landscape. Keep an eye on their upcoming financial reports for more detailed performance metrics.

Even in our increasingly digital world, the physical infrastructure of banking remains critical, and that's where NCR Atleos Corp (NATL) shines. This company is a key player in self-service banking solutions, primarily known for its ATMs, ATM-as-a-Service offerings, and cash distribution networks for banks and retailers. While it might not sound as 'flashy' as some other fintechs, providing essential infrastructure is a vital and often stable business. NCR Atleos had a market capitalization of approximately $2.5 billion, making it a significant small-cap player in the financial infrastructure space. The company has shown steady performance recently, with its revenue growing by around 4%. More encouragingly, its net income is expected to rise sharply in 2025, driven by growth in recurring services and outsourced solutions. This focus on recurring revenue is a big plus, as it provides a more predictable income stream for the company. As banks continue to modernize their operations and look for efficient ways to manage their physical presence and cash flow, companies like NCR Atleos are well-positioned to benefit. Their 'ATM-as-a-Service' model, for instance, allows financial institutions to outsource the management and maintenance of their ATM networks, reducing their operational burden and potentially increasing efficiency. For investors seeking exposure to the foundational technology that keeps the traditional financial system running, NCR Atleos offers a compelling, albeit less talked about, fintech opportunity.
