What Block, Inc. told the SEC could break it.
Block's disclosures reflect a fintech exposed both to bitcoin and to financial plumbing it doesn't control. Selling bitcoin to Cash App customers made up 35% of total 2025 revenue (though only about 4% of gross profit), and that line swings with bitcoin's price and trading volume — it fell $1.9 billion, or 18%, in 2025 on lower volume. To move money at all, it depends on third parties it doesn't own — card networks, acquiring and issuing processors, card issuers, bank partners, and the Federal Reserve's ACH — and relies on only a limited number of acquiring processors in some markets. That places it under heavy financial regulation (AML, anti-corruption, OFAC sanctions, and money-transmitter licensing), and tariffs on its imported Square hardware further pressure those products' margins.
4 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Regulatory & policy
- AML / FCPA anti-corruption / OFAC sanctions and money-transmitter licensingmedium
Block is subject to anti-money-laundering, anti-corruption (FCPA, UK Bribery Act), and OFAC economic/trade sanctions laws across jurisdictions, plus state/federal money-transmitter and lending licensing with examination authority — noncompliance risks license loss, enforcement actions, and penalties.
“We are subject to anti-money laundering ("AML"), anti-corruption, and economic and trade sanctions laws and regulations in the United States and other jurisdictions in which we operate.”
SEC filing →As of 2026 - tariffs on imported Square hardware devicesmedium
Some of Block's Square hardware devices are manufactured outside the U.S. and subject to import tariffs that negatively affect gross margin on those products; resulting price increases may reduce demand or competitiveness.
“Some of our hardware devices manufactured outside of the United States are subject to tariffs when imported to the United States. These tariffs negatively affect our gross margin on the impacted products, and increases in our pricing as a result of tariffs may adversely affect demand for our products or reduce the competitiveness of our products if our competitors do not make similar pricing adjustments.”
Commodity & input dependence
- bitcoin price and trading volume (Cash App bitcoin)medium
Bitcoin ecosystem revenue (primarily the sale amount of bitcoin sold to Cash App customers) was 35% of Block's total 2025 revenue (though only ~4% of gross profit) and fluctuates with customer demand and the market price of bitcoin — 2025 bitcoin revenue fell $1.9B (18%) on lower trading volume.
“As bitcoin ecosystem revenue is primarily the total sale amount of bitcoin sold to customers, the amount of bitcoin ecosystem revenue recognized will fluctuate depending on customer demand as well as changes in the market price of bitcoin.”
Supplier concentration
- third-party payment infrastructure (card networks, processors, issuers, bank partners, ACH)medium
Block depends on third parties it does not control — payment card networks, acquiring/issuing processors, card issuers, a carrying broker-dealer, bank and financial-institution partners, and the Federal Reserve ACH — to process transactions and settle funds, and relies on a limited number of acquiring processors in some jurisdictions; their failure or withdrawal could materially harm its business.
“To provide our products and services, we rely on third parties that we do not control, such as the payment card networks, our acquiring and issuing processors, the payment card issuers, a carrying broker-dealer, bank partners, various financial institution partners, systems like the Federal Reserve Automated Clearing House, and other partners.”

“In addition, we rely on app marketplaces, such as the Apple App Store and Google Play, to drive downloads of our mobile apps. Apple, Google, or other operators of app marketplaces regularly make changes to their marketplaces, and those changes may make access to our products and services more difficult.”
