Two High-Growth Stocks Worth Investing In Right Now: Robinhood and Nu Holdings

If you’re looking for good stock to invest your capital in right now, consider this: the most impactful investment decisions often begin with a simple $1,000 position. What matters is not the initial amount, but identifying businesses with rising revenue and expanding profit margins—hallmarks of sustainable growth. Two fintech companies currently meet these criteria and could shape your investment portfolio: Robinhood Markets and Nu Holdings.

Both companies operate in fast-growing niches within the financial services sector. One dominates the retail investment trading space in North America, while the other leads the digital banking revolution sweeping through Latin America. Their contrasting markets and complementary business models make them compelling candidates for investors seeking exposure to different growth drivers.

Robinhood Markets: Capitalizing on Active Trading and Market Innovation

Robinhood Markets (NASDAQ: HOOD) has built an impressive user base of more than 27 million funded customers on its trading platform, and there’s significant runway for expansion ahead. The platform attracted a 7% increase in its customer base year-over-year in 2025, while simultaneously boosting the average revenue per user by 16%—a powerful combination that demonstrates both customer acquisition efficiency and monetization strength.

The company’s core revenue engine is performing exceptionally well. Total revenue surged 27% year-over-year, with particular strength in stocks and options trading revenue. While cryptocurrency revenue experienced a 38% decline year-over-year (a function of Bitcoin’s recent weakness), this segment demonstrated dramatic recovery potential by more than quadrupling in the third quarter alone, suggesting it can reaccelerate rapidly once digital assets regain momentum.

Profitability metrics have also strengthened. Net income climbed year-over-year, and excluding a one-time $424 million tax benefit and regulatory adjustment from Q4 2024, the company still generated solid earnings growth. This stock to invest in has positioned itself at the intersection of two major market forces: the ongoing digitization of retail investing and the explosive growth in prediction markets.

The prediction market segment represents the newest catalyst for Robinhood’s expansion. Event contract trading volumes reached 8.5 billion in Q4 2024, and the momentum has carried into 2026 with 3.4 billion event contracts traded in January alone. This emerging category could become a significant revenue contributor as regulatory clarity improves and adoption accelerates.

From a valuation perspective, Robinhood’s stock has declined more than 30% year-to-date despite gaining more than 100% over the past five years. This pullback presents a potential buying opportunity for investors convinced of its long-term dominance in retail trading infrastructure.

Nu Holdings: Dominating Emerging Market Digital Banking

Nu Holdings (NYSE: NU) operates as Latin America’s largest bank and has built its entire business model on a branch-free, entirely digital platform. This structural advantage translates directly into lower operating costs, higher profit margins, and more competitive product offerings compared to traditional banking competitors.

The company’s penetration in its core market is already substantial: over 60% of Brazil’s adult population uses Nu Holdings’ services. Beyond its home market, the company is expanding aggressively into Mexico, Colombia, and throughout the broader Latin American region. This geographic expansion combined with a high-growth market environment produced 39% year-over-year revenue growth during Q3 2025.

Customer acquisition remains strong, with 4 million net new customers added in Q3 to reach a total user base exceeding 127 million. More importantly, the 83% activity rate indicates that the vast majority of these users actively engage with the platform for investing, saving, and borrowing—a metric that has remained consistently high throughout the past year.

Multiple product lines within Nu’s ecosystem are experiencing exceptional expansion. Credit card balances and loans grew 45% year-over-year, while interest-earning investment portfolios expanded 58% from the prior year. These revenue streams carried through to the bottom line: net income surged 41%, resulting in an impressive 41% net profit margin that rivals or exceeds many technology-focused financial institutions.

This combination of rapid product growth, margin expansion, and geographic opportunity in one of the world’s fastest-developing regions suggests Nu Holdings possesses the fundamental ingredients for sustained outperformance. For investors right now seeking exposure to emerging market financial services disruption, this stock represents a compelling option.

Why These Stocks Stand Out for Your Portfolio Today

Finding good stocks to invest in requires identifying companies that prove both growing and increasingly profitable. Robinhood and Nu Holdings satisfy both requirements while operating in distinct market ecosystems. Robinhood benefits from active trading cycles, prediction market adoption, and cryptocurrency adoption waves. Nu Holdings captures the structural shift toward digital banking in high-growth emerging markets.

The appropriate investment decision depends on your risk tolerance, geographic exposure preferences, and market cycle positioning. Both companies have experienced volatility reflecting broader market conditions and sector-specific dynamics. However, their fundamental business models—high-growth revenue combined with expanding profitability—remain intact.

Before committing capital, examine each company’s quarterly earnings reports, competitive positioning, and regulatory environment. The most successful long-term investors combine thorough research with conviction in the underlying business thesis. A $1,000 position today in the right stock can compound into substantial wealth over a decade-plus timeframe, and these two fintech leaders merit consideration as potential core holdings in a growth-focused portfolio.
