This in-depth comparison examines Afterpay Limited and Block Inc across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching Afterpay Limited on its own, evaluating Block Inc, or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Afterpay Limited and Block Inc is widest.

On the headline numbers, annual revenue is ~$596.4M (FY2021) for Afterpay Limited and $24.2B (FY2025) for Block Inc, while their respective market capitalizations stand at N/A and $44.5B. Afterpay Limited is headquartered in Australia and Block Inc in United States, and those different home markets shape how each company competes.

Afterpay Limited: Nick Molnar and Anthony Eisen founded Afterpay in Sydney in 2014. The listed company maintained its corporate base in Melbourne, expanded internationally, and used the Clearpay name in the United Kingdom. Block acquired all issued shares through a scheme of arrangement completed on January 31, 2022. The company is headquartered in Melbourne, Australia. Originating in Sydney, Australia, the fintech darling effectively mainstreamed the global "Buy Now, Pay Later" movement before being swallowed by Block (formerly Square) in a historic multibillion-dollar buyout.

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. The company is headquartered in Oakland, California (officially distributed). The financial technology powerhouse (formerly Square) was famously founded in San Francisco, California by Twitter co-founder Jack Dorsey to allow small merchants to accept credit cards via a tiny plastic headphone jack plug.

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

Afterpay Limited business model: Before the Block acquisition, Afterpay earned most income from merchant fees on purchases processed through its platform, with a smaller contribution from customer late fees. Customers generally paid four installments over six weeks and paid no interest. Block now reports Afterpay within its consolidated results rather than as a standalone public company.

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.

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

Afterpay Limited competitive advantage: Afterpay combines installment checkout with a merchant directory and an established consumer brand. Block can connect the product to Square sellers and Cash App customers, although Block identifies merchant retention and product integration as acquisition risks.

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.

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

Afterpay Limited growth strategy: Block stated at closing that it intended to add Afterpay BNPL to Square checkout, let Afterpay customers manage installments in Cash App, and help Cash App customers discover sellers and BNPL offers. Subsequent expansion has focused on those seller and consumer connections.

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.

A closer look at the financial trajectory of Afterpay Limited and Block Inc rounds out the comparison.

Afterpay Limited: Afterpay reported standalone results in Australian dollars before Block acquired it. Total income rose from ~$903,000 (A$1.4 million) in FY2016 to ~$596 million (A$924.6 million) in FY2021, while FY2021 statutory loss after tax was ~$103 million (A$159.4 million). Block does not publish a comparable standalone Afterpay revenue series after the January 2022 close. Afterpay was acquired by Block, Inc. (formerly Square) in 2022 for approximately $29 billion, one of the largest acquisitions in Australian corporate history.

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. Block, Inc. maintains a formidable presence in the fintech space, with a market valuation generally exceeding $40 billion.
