PayPal vs. Block: Which Fintech Stock Is the Better Buy Right Now?

Read MoreHide Full Article

Key Takeaways

  • PayPal is focusing on checkout, Venmo, payment services' profitability and next-gen vectors.
  • Block is expanding Cash App and Square with new features like Cash App Pools and Square AI.
  • PayPal offers a broader global reach, while Block remains more U.S.-centric and youth-focused.

PayPal Holdings (PYPL - Free Report) and Block (XYZ - Free Report) have long been at the center of fintech investing. Both companies are reshaping digital payments and commerce, but they approach the opportunity from different angles: PayPal with its global two-sided payments and commerce platform, and Block with its dual ecosystem of Square and Cash App. 

Their latest second-quarter 2025 earnings highlight diverging strengths — PayPal’s improving profitability and platform innovation versus Block’s network expansion and product velocity. Let’s weigh the pros and cons of each to find out which deserves a spot in your portfolio.

The Case for PayPal

PayPal delivered a solid second quarter, with revenues up 5% year over year to $8.3 billion, Total Payment Volume (“TPV”) climbing 6% and non-GAAP EPS growing 18% to $1.40. Transaction margin dollars, excluding interest on customer balances, rose 8%, underscoring the health of its core payments engine. Importantly, PayPal raised its full-year EPS and transaction margin dollar guidance, signaling confidence in sustained momentum.

Strategically, PayPal is executing on four growth pillars: winning checkout, scaling omni and Venmo, driving payment services profitability, and investing in next-gen vectors like AI, ads and stablecoins. Venmo, in particular, grew revenues more than 20% year over year, with Venmo Debit Card monthly active account growth of more than 40% and Pay with Venmo TPV soaring 45%. The company is also rolling out PayPal World, connecting major wallets like Mercado Pago, NPCI’s UPI and Tenpay Global to broaden its global reach. These initiatives strengthen its relevance in both e-commerce and offline retail while laying the groundwork for new revenue streams.

That said, PayPal still faces challenges. While TPV rose 6%, payment transactions fell 5% as unbranded processing weighed on volumes. Engagement per user also slipped slightly, with payment transactions per active account on a trailing 12-month basis declining 4% year over year. Still, excluding low-margin processing, engagement improved. 

Compared to Block, PayPal offers greater global scale and a stronger branded checkout presence, but its growth profile is steadier rather than explosive. Investors seeking a combination of resilience, profitability and innovation may find PayPal’s improving fundamentals more compelling.

The Case for Block

Block’s second quarter was a story of strong gross profit growth but softer top-line performance. Revenues declined 2% year over year to $6.05 billion, missing expectations, but the gross profit rose 14% to $2.54 billion, with Cash App up 16% and Square up 11%. Adjusted operating income surged 38% with a margin of 22%, showing that scale and efficiency are starting to pay off.

Block’s strength lies in Cash App’s momentum. With $1.5 billion in gross profit, Cash App continues to serve as a financial hub for younger customers, expanding into P2P, commerce, banking and bitcoin. 

The company introduced new products like Cash App Pools for group payments, Afterpay integrations and enhanced borrowing features — all deepening engagement. Meanwhile, Square is seeing double-digit GPV growth and rolling out innovations like Square AI and Tap to Pay on iPhone. Together, these ecosystems reinforce Block’s ambition to be a comprehensive financial operating system.

Still, Block’s journey isn’t without headwinds. Bitcoin remains a meaningful part of Block’s strategy, but it also adds volatility. Competition is fierce, particularly in consumer payments, where PayPal and other global networks have more entrenched merchant acceptance. While Block’s innovation velocity is impressive, it is still more U.S.-centric and reliant on Cash App’s young demographic, leaving it somewhat narrower in scope than PayPal’s global reach.

Conclusion: PayPal Has the Edge Right Now

Both PayPal and Block posted strong Q2 results, but their paths diverge.
