Two Best Fintech Stocks to Buy With $500 Today

The fintech revolution has fundamentally reshaped how investors access markets and how consumers manage their finances. Over the past decade, financial technology companies have outpaced traditional institutions by offering streamlined services powered by digital innovation. This trend shows no signs of slowing. According to Fortune Business Insights, the global fintech sector is projected to grow at a compound annual growth rate (CAGR) of 16.2% through 2032, as more people migrate from legacy banking systems to modern digital alternatives. For investors seeking the best fintech stocks to buy, identifying industry leaders with early-mover advantages is critical.

Two standout opportunities—Robinhood Markets and Affirm Holdings—demonstrate how disruption in financial services can create substantial wealth. Both companies have exhibited volatility, yet their long-term trajectory suggests a $500 investment today could potentially multiply several-fold over the next decade.

Robinhood: How Commission-Free Trading Captured Retail Investors

Robinhood fundamentally altered the competitive landscape by eliminating trading commissions and introducing an intuitive mobile-first platform. The company’s user-friendly app gamified the investment experience, drawing millions of retail customers away from traditional brokerages.

The growth metrics tell a compelling story. Between 2020 and 2024, Robinhood’s funded customer base more than doubled—rising from 12.5 million to 25.2 million. During this same period, annual revenue expanded at a 32% CAGR, despite a temporary slowdown in 2022 when pandemic-era enthusiasm for meme stocks and cryptocurrencies cooled. By Q3 2025, the company had grown to 26.8 million funded customers, demonstrating sustained momentum.

A particularly striking development is Robinhood’s Gold subscription tier, which provides margin trading privileges, enhanced interest rates, and premium features for $5 monthly. Gold subscriber count surged 77% year-over-year to 3.9 million users, indicating strong monetization traction.

Looking forward, Wall Street analysts forecast Robinhood’s revenue and adjusted EBITDA will grow at respective CAGRs of 27% and 37% through 2027. This expansion will be fueled by the company’s evolution into a comprehensive fintech platform—expanding beyond stock trading into banking services, wealth management, and AI-enhanced investment tools. At an enterprise value of $118.2 billion, Robinhood commands a valuation of 36 times next year’s adjusted EBITDA, which appears reasonable given its growth profile and runway to capture additional customers from legacy brokerages and banks.

Affirm: Buy-Now-Pay-Later as a Disruptive Financial Service

Affirm operates in the “buy now, pay later” (BNPL) space, offering consumers the ability to split purchases into installment plans without traditional credit cards or compound interest charges. This model has profound implications for two constituencies: cost-conscious consumers who lack credit cards, and merchants seeking lower transaction costs than the 1.5%-3.5% fees levied by credit card networks.

Affirm’s expansion has been remarkable. From fiscal year 2021 through fiscal 2025 (ended June 2025), the company’s active consumer base grew from 7.1 million to 23.0 million—a more than threefold increase. Simultaneously, active merchants exploded from 29,000 to 376,800. The company’s gross merchandise volume (GMV) climbed from $8.3 billion to $36.7 billion, reflecting accelerating adoption.

By Q1 of fiscal 2026, momentum continued: active consumers reached 24.1 million and active merchants expanded to 419,000. Importantly, the company maintained disciplined underwriting, keeping 30+ day delinquencies below 3%, demonstrating it could grow without sacrificing credit quality.

Affirm’s business model exhibits natural resilience during economic downturns. Consumers typically intensify their use of BNPL services as discretionary spending becomes constrained, making Affirm’s revenue stream relatively insulated from macroeconomic headwinds. Analysts project Affirm’s revenue and adjusted EBITDA will expand at respective CAGRs of 25% and 131% from fiscal 2025 through 2028—with EBITDA growth particularly explosive as the company reaches profitability scale. Trading at an enterprise value of $27.2 billion, or 24 times current-year adjusted EBITDA, Affirm appears surprisingly affordable for a company poised to convert cost-conscious consumers and merchants away from legacy credit card infrastructure.

Why These Best Fintech Stocks Merit Investor Attention

The case for owning the best fintech stocks to buy rests on a straightforward thesis: digital financial services are displacing entrenched incumbents at accelerating speed. Both Robinhood and Affirm possess the market position, user traction, and financial leverage to dominate their respective categories over the coming decade. A $500 investment in either company today could represent meaningful portfolio exposure to the fintech transformation reshaping how people invest and consume financial services.
