Block wants credit to look at more of the truth. This week it agreed to open Cash App Score, its internal read on a customer’s financial life, to outside lenders through Nova Credit’s underwriting platform. The case for it is genuinely strong. The reason Block is doing it now is not the one in the press release.
The Strong Case, Stated First
Start with what Block can actually show. Its own figures say Cash App Borrow approves 38 percent more customers than a traditional credit score would, at the same loss rate, and that 70 percent of active Borrow customers carry a FICO score below 580, the range where conventional underwriting mostly says no. Nova Credit’s platform will let outside lenders plug that same score into underwriting for credit cards, auto loans, device financing, personal loans and tenant screening, verticals the release is careful to note are ones “where Cash App does not compete.” Juan Hernandez, Block’s head of credit and underwriting, put the mission in plain terms: “At Block, we believe people should be able to use their own financial history to unlock opportunity, on their terms.”
That is a real problem, honestly described. Cash flow data, spending, saving, repayment behavior, paycheck deposits, peer-to-peer transfers, genuinely does capture financial reliability that a FICO score misses, particularly for the sizable share of Cash App’s own user base sitting below the conventional lending line. A lender who can see that behavior has a better basis for a yes than one working from bureau data alone.

The Part the Press Release Undersells
Here is the counter-argument the release does not make, because press releases do not make it for themselves: opening Cash App Score to competitors is not simply generosity toward underserved borrowers. It is a way for Block to monetize its data advantage without expanding its own balance-sheet lending, which carries capital and regulatory costs Block has been visibly careful about. Notice the boundary the release itself draws: the score goes to lenders in verticals where Cash App does not compete. That is not an accident of scope. It is Block deciding it makes more money selling the signal than fighting for the loan.
That is a defensible business decision. It is not the same decision as “expanding access,” even though the two overlap in this case. A data supplier optimizing for distribution across many lenders’ underwriting stacks, through a single intermediary in Nova Credit, is building a business model that looks less like alternative credit and more like a proprietary bureau, one built on Cash App’s own transaction data rather than the tradelines the incumbent bureaus rely on.
Why the Distinction Matters
Alternative data has been pitched as a fix for traditional credit scoring’s blind spots for years. Even the incumbent bureaus are now racing to make their own scores more visible and more portable, which suggests the industry accepts that the old model of an opaque, infrequently updated score is losing ground. The open question is not whether cash-flow-based scoring is more accurate. On Block’s own numbers, it plainly can be. The question is who ends up owning the new scoring layer once it scales, an incumbent bureau retooling with new data, a bank-chartered lender bringing underwriting in-house, or a payments company that reaches this data first because it already sits inside the transaction flow.
Other AI-native underwriters have chosen to become the lender directly, charter and all, rather than sell their model to someone else’s book. Block chose distribution over ownership of the loan. That is a narrower bet, and a lower-risk one, but it is worth naming as a strategic choice, not treating it as a philanthropic one.
What It Means for the Credit Leader
Lenders evaluating this partnership should ask Nova Credit and Block the question the release does not answer: what happens to pricing and access once Cash App Score becomes a standard input across many underwriting stacks rather than a niche one. A score that changes lending outcomes for millions of thin-file borrowers is valuable exactly because it is scarce today. Its value to any single lender, and its price, will change once every competitor has the same input. Evaluate the score on what it predicts, not on the inclusion narrative attached to its launch.
