Block, the payments company behind Cash App, just made a quiet move that could reshape how millions of Americans get approved for loans. For the first time, Block is opening its proprietary credit scoring system to outside lenders, partnering with Nova Credit to share the data it has spent years building inside Cash App. Wall Street noticed: the company's full-year profit forecast just went up, and analysts are pointing to lending as the reason.

The number that matters is 59%. That is how much Block's consumer lending origination volume grew in the second quarter compared to a year earlier. The product driving it is Cash App Borrow, a short-term credit feature built into the app. While the total number of monthly active users grew only modestly (about 3%), the people already on the platform are borrowing more. That is a meaningful distinction. Block is not just adding users; it is deepening what existing users do inside the app.

From payment app to credit bureau

The Credit Score Block has built, called Cash App Score, was previously kept internal. It drew on transaction data flowing through Cash App to assess how creditworthy a user actually is, rather than relying on traditional credit history the way most lenders do. Now, Block is licensing that signal to outside lenders through Nova Credit's platform.

This matters for ordinary people in two ways. First, it could help people who are effectively invisible to traditional credit systems get access to loans they currently can't get. If a lender can see that you reliably receive direct deposits, pay your bills through Cash App, and have a consistent spending pattern, that tells a story that a FICO score often misses. Second, it creates a new revenue line for Block from the same data it already holds, without needing to make any new loans itself.

That is a shift in what kind of company Block actually is. It started as a payment processor. It became a consumer finance app. It is now beginning to look like a financial data business, selling insight rather than just transactions.

The quarter that prompted all this optimism

Block's second quarter results gave the company room to make these moves with confidence. Revenue came in at $6.62 billion, up 9.3% from the same period last year. Gross profit grew 25%, reaching $3.17 billion. Adjusted earnings per share hit $1.02, up 65% year over year. The operating margin hit a record 27%.

On the back of those numbers, management raised its full-year guidance. The company now expects gross profit to exceed $12.5 billion for 2026, with an adjusted operating margin of 28% and earnings per share growth of roughly 70%.

The lending business is doing most of the heavy lifting. Block said its Financial Solutions gross profit growth was driven primarily by Cash App Borrow, and commerce volume through the platform grew 17%. AI-driven cost efficiencies are contributing too, though the specifics on those savings were not broken out in detail.

The risk hiding in the growth story

There is a tension worth naming here. Consumer lending grows fastest when people need credit most. A 59% jump in borrowing through a short-term credit app could reflect healthy engagement, or it could reflect users who are stretched thin and turning to Cash App when other options run out. Block has not disclosed its delinquency rates or loss provisions in the summary data available, so the credit quality underlying that growth remains a question.

What is clear is that Block is betting its next chapter on becoming the financial infrastructure for people who have historically been underserved by traditional banks. If that bet holds, the data it collects becomes more valuable every quarter. If credit quality deteriorates, the optimism built into that 70% earnings-growth forecast comes apart quickly.

For now, the numbers are pointing one direction. The question is whether the borrowers behind them are.
