Block Inc: Block, formerly Square, started in 2009 with a small white card reader that plugged into a phone's headphone jack and let food trucks, artists and coffee shops take card payments. It now runs Square for sellers, Cash App for 59 million monthly transacting customers, Afterpay for buy now, pay later, and smaller units including the TIDAL music service, the Bitkey bitcoin wallet and Proto mining hardware. Its shares trade on the New York Stock Exchange as XYZ, a ticker adopted in January 2025, and it joined the S&P 500 on July 23, 2025. Co-founder Jack Dorsey, who also co-founded Twitter, has led it since the start.

PayPal Holdings, Inc.: PayPal grew out of the 2000 merger of Confinity and X.com, became the default way to pay on eBay, was owned by eBay from 2002 to 2015, and has been an independent Nasdaq company (PYPL) since July 2015. Today it runs the PayPal wallet and checkout button, Venmo in the U.S., Braintree for large merchants such as marketplaces and ride-hailing apps, Xoom for remittances, Zettle for in-person payments, Paidy in Japan, and the PYUSD stablecoin. In 2025 it handled about $1.79 trillion of payment volume and earned $33.17 billion of revenue.

Block Inc and PayPal Holdings, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Block Inc and PayPal Holdings, Inc..

Block Inc business model: Block runs a two-sided network. On the seller side, Square charges a fee on each card payment (in the U.S. on its free plan, 2.6% plus 15 cents in person and 3.3% plus 30 cents online) and adds paid software, hardware, payroll, banking and Square Loans. On the consumer side, basic Cash App transfers are free; the app earns from Cash App Card interchange, instant transfer fees, Borrow short-term loans, Afterpay pay-in-four plans and the spread on bitcoin sales. Gross profit is the number management steers by: $10.36 billion in 2025, with Cash App contributing $1.83 billion and Square $993 million in the fourth quarter alone. The long-term aim is to connect both sides, so that a Cash App customer pays a Square seller through Cash App Pay, Afterpay or the Neighborhoods local rewards program and Block keeps the economics at both ends.

PayPal Holdings, Inc. business model: PayPal makes most of its money from transaction revenue: fees merchants pay when customers check out with the PayPal or Venmo button (branded checkout), fees on unbranded card processing through Braintree, and consumer fees such as instant transfers, cross-border and currency conversion charges. Branded checkout carries the highest margin because PayPal controls the customer relationship; Braintree adds large volume at thinner margins. A second line, revenue from other value-added services, covers interest on customer balances, PayPal Credit and buy now, pay later loans, partner and referral fees. In Q2 2026, transaction revenue was about $7.8 billion of $8.68 billion total, and transaction margin dollars, the profit after processing costs and losses that management tracks most closely, were about $3.9 billion.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Block Inc stack up against those of PayPal Holdings, Inc..

Block Inc competitive advantage: Block's advantage is owning both ends of many small transactions. Cash App's peer-to-peer network spreads by itself, since receiving money means downloading the app, and every added product (the Cash App Card, direct deposit, Borrow, Afterpay) raises revenue per customer without new acquisition cost. Square sellers run payments, staff, inventory and loans on one system, so switching costs grow with each product they adopt. Square Financial Services, a Utah industrial bank that opened in March 2021, lets Block originate Square Loans and Cash App Borrow loans on its own charter, which few fintechs have.

PayPal Holdings, Inc. competitive advantage: PayPal's edge is a two-sided network: about 439 million active accounts at the end of 2025 on one side and millions of merchants on the other. Shoppers who already store cards and bank accounts in PayPal can pay without typing details, and merchants add the button because it can lift conversion with those shoppers. Processors such as Stripe and Adyen serve merchants but do not own a consumer wallet of that size. Two decades of transaction data also feed PayPal's fraud and risk models, which matters in a business where losses can erase margin.

Future prospects matter as much as current results. The growth strategies below explain how Block Inc and PayPal Holdings, Inc. each plan to expand from here.

Block Inc growth strategy: Block's 2026 plan has four parts. Square is selling to larger and international sellers through a field sales team and independent sales organization partners; international GPV grew 28% in the second quarter of 2026. Cash App wants to be the main bank account for people with several income sources, using direct deposit and Cash App Green rewards status; primary banking actives reached 9.4 million in June 2026, up 17%. Lending is expanding through Borrow, Afterpay and Square Loans, all originated more cheaply now that Block's own bank handles Borrow. And Neighborhoods links Square sellers with nearby Cash App customers; it passed $1 billion of annualized seller GPV in June 2026. Bitcoin remains a long-term bet through Bitkey and Proto mining rigs, which began shipping in late 2025.

PayPal Holdings, Inc. growth strategy: Under Enrique Lores, PayPal's 2026 plan has three parts. First, restore growth in branded checkout, which rose only about 2% in Q2 2026, by improving conversion, Fastlane guest checkout and agentic or AI-assisted commerce. Second, make Venmo and Braintree pull more weight: Venmo is being pushed into merchant payments and debit cards, while Braintree is priced for profit rather than volume. Third, fund reinvestment through cost cuts, including a reported plan to reduce headcount by about 20% over two to three years and roughly $1.5 billion of savings, plus share repurchases supported by at least $6 billion of expected 2026 adjusted free cash flow.

A closer look at the financial trajectory of Block Inc and PayPal Holdings, Inc. rounds out the comparison.

Block Inc: Revenue was nearly flat in 2025, $24.19 billion against $24.12 billion, because bitcoin sales fell from $10.36 billion to $8.50 billion. Gross profit, which strips out the cost of the bitcoin Block resells, rose 17% to $10.36 billion and adjusted operating income rose 30% to about $2.3 billion. Net income attributable to common stockholders was $1.31 billion, down from $2.90 billion in 2024, a year lifted by a large fourth-quarter tax benefit. 2026 opened with a $308.7 million first-quarter net loss as layoff costs landed (about $495 million of restructuring charges across the first half), then second-quarter gross profit grew 25% to $3.17 billion with a record 27% adjusted operating margin. Block now guides to $12.51 billion of 2026 gross profit and $3.47 billion of adjusted operating income. It bought back $2.3 billion of stock in 2025, had $4.6 billion of repurchase authorization left at June 30, 2026, and pays no dividend.

PayPal Holdings, Inc.: PayPal is large and profitable, but growth has slowed. Revenue climbed from $21.45 billion in 2020 to $33.17 billion in 2025, yet annual growth fell from about 21% to about 4%. Net income reached $5.23 billion in 2025, up from $4.15 billion in 2024. In Q2 2026 revenue rose 5% to $8.68 billion (3% currency-neutral), total payment volume rose 10% to $486.4 billion, transaction margin dollars rose 1% to about $3.9 billion, and non-GAAP EPS was $1.38. Management then raised full-year 2026 non-GAAP EPS guidance to about $5.38 and guided to at least $6 billion of adjusted free cash flow, most of which goes to buybacks. The stock still trades at roughly 10 times earnings, which shows how skeptical investors are about long-term branded checkout growth.
