FICO Stock Tumbles on Report of Credit Bureau Requirement Change
FICO stock fell sharply after hours on October 1 after a report said the Federal Housing Finance Agency (FHFA) is considering requiring mortgage lenders to pull credit data from two major credit bureaus instead of three. The reported change would add another potential challenge for Fair Isaac as the U.S. mortgage industry moves toward greater competition in credit scoring and reporting.
Fair Isaac shares fell about 7% in after-hours trading, while TransUnion also declined about 6%, according to the report. The market reaction reflects concerns that a two-bureau system could reduce demand for traditional three-bureau, or “tri-merge,” credit reports.
Importantly, the two-bureau change was reported as a potential future move, not a finalized FHFA requirement. FHFA's current published policy says the introduction of VantageScore 4.0 has not initially changed existing credit-reporting requirements, including tri-merge and bi-merge reporting.
What Is Behind the FICO Stock Selloff?
The latest decline comes after an already difficult period for FICO stock.
Investors have been reassessing Fair Isaac's position in the U.S. mortgage market after FHFA expanded access to VantageScore 4.0. On September 9, FHFA said all approved Fannie Mae and Freddie Mac lenders could use VantageScore 4.0 when originating and selling eligible loans, while Classic FICO remained an approved option.
That change gives lenders greater choice between the traditional Classic FICO model and VantageScore 4.0.
The latest report adds another potential layer to the disruption. Instead of pulling credit information from all three major bureaus — Equifax, Experian and TransUnion — lenders could eventually be allowed or required to use data from only two.
For FICO, the concern is indirect but important: changes to the underlying mortgage-credit process can affect how often scores are ordered, which scoring models are used and how much lenders are willing to pay.
What Does a Two-Bureau Credit Report Mean?
The U.S. mortgage industry has traditionally used a tri-merge credit report, which combines information from Equifax, Experian and TransUnion.
A two-bureau, or “bi-merge,” approach would reduce that requirement to data from two of the three major credit reporting companies.
The idea is part of a broader effort to lower costs and increase competition in mortgage credit reporting. FHFA has previously explored bi-merge reporting as part of its modernization of credit-score requirements.
The distinction matters because credit bureaus provide the underlying consumer credit data, while FICO and VantageScore provide credit-scoring models that use that information to generate scores.
So the reported policy would potentially affect both sides of the ecosystem, although in different ways.
For Equifax, Experian and TransUnion, fewer required bureau reports could mean less demand for traditional three-bureau reports. For FICO, the concern is that a smaller reporting process could make the economics and workflow around mortgage credit scoring more competitive.
FHFA Has Already Opened the Door to VantageScore
The credit-reporting story cannot be separated from the earlier changes to mortgage scoring.
FHFA and the government-sponsored mortgage enterprises have been modernizing the credit-score framework for several years. In April 2026, FHFA announced implementation of VantageScore 4.0 and FICO 10T as part of the transition.
By September 9, all approved Fannie Mae and Freddie Mac lenders were permitted to use VantageScore 4.0 without obtaining prior written approval.
Under the current interim framework, lenders can choose Classic FICO or VantageScore 4.0 for eligible loans. FHFA says lenders must use the same scoring model for all borrowers on a particular loan, but can choose different models across different loans.
This is a significant change from an environment in which Classic FICO had been the established model for mortgage loans sold to Fannie Mae and Freddie Mac.
Rocket Mortgage Adds to the Pressure
The competitive shift became more tangible when Rocket Mortgage announced on September 28 that it would make VantageScore 4.0 its preferred scoring model for all eligible loans during the fourth quarter of 2026.
Rocket said testing showed that VantageScore helped more clients qualify and reduced credit-scoring costs. It said that, so far in 2026, it had obtained 1.4 million credit reports using both VantageScore and FICO as part of its evaluation.
The decision does not eliminate FICO from Rocket's mortgage business. Rocket said FICO scores would continue to be used for certain products, including investment-property and second-home mortgages, home-equity loans, FHA loans and jumbo loans. Its broker-facing Rocket Pro business will also provide both VantageScore and FICO.
Nevertheless, the announcement demonstrates how lenders could respond when multiple scoring models become available.
Why This Matters for FICO's Business
FICO's scoring business is highly important to its overall financial model, and mortgage scoring has historically provided the company with a particularly strong position.
The introduction of competing models creates a different commercial environment. If lenders increasingly choose VantageScore for eligible mortgages, FICO could face pressure on score volumes, pricing and its position in mortgage underwriting.
The potential bi-merge change could add to that pressure by reducing the number of credit reports required for mortgage applications.
However, it would be premature to assume that a two-bureau system automatically translates into a proportional decline in FICO's revenue.
FICO has several scoring products and serves lenders across credit cards, auto finance, personal lending and other financial services. It also continues to develop newer models.
For example, FICO Score 10T is scheduled to become available for FHA mortgage underwriting beginning January 1, 2027. FICO says the model uses trended credit and rental-payment data and is designed to provide a more detailed view of borrower behavior.
That means the mortgage-market transition is likely to involve competition between multiple newer scoring models rather than a simple replacement of FICO by VantageScore.
The Report Is Not Yet a Final Policy
This is one of the most important points for investors.
The October 1 report said FHFA could direct Fannie Mae and Freddie Mac toward a two-bureau requirement and that an announcement could come as early as October 12, when FHFA Director William Pulte is scheduled to speak at a mortgage-industry conference in Chicago. FHFA had not immediately commented on the report.
Meanwhile, FHFA's published September policy says the current inclusion of VantageScore 4.0 does not initially change existing credit-reporting requirements, including tri-merge and bi-merge reporting.
Therefore, investors should distinguish between the reported potential policy change and the rules currently in effect.
That distinction is particularly important after the sharp move in FICO shares because market expectations can change well before a regulatory proposal becomes final.
What Investors Should Watch Next
The next major catalyst is likely to be any formal FHFA announcement regarding credit-reporting requirements.
Investors should monitor:
FHFA policy announcements: Whether a bi-merge requirement is formally proposed or adopted.
Fannie Mae and Freddie Mac guidance: The actual implementation rules will determine how lenders operate.
VantageScore adoption: Greater lender use could increase competitive pressure on FICO.
Rocket Mortgage results: Its VantageScore rollout provides an early real-world test of lender adoption.
FICO 10T adoption: Its planned FHA availability from January 2027 could give FICO another opportunity to compete with VantageScore.
Pricing and volumes: Changes in the number of scores ordered and the price paid for them could have direct financial implications for FICO.
The credit bureaus also deserve attention because a move away from mandatory tri-merge reporting could affect the economics of their mortgage-reporting businesses.
Bottom Line
FICO stock's latest decline reflects investor concern over a reported potential shift toward two-bureau mortgage credit reporting, coming shortly after FHFA expanded lender access to VantageScore 4.0.
The reported bi-merge change is not yet a finalized requirement, but it highlights how quickly the U.S. mortgage-credit ecosystem is changing. FICO now faces a more competitive scoring environment, while Equifax, Experian and TransUnion also face possible changes to traditional credit-reporting volumes.
For investors, the key issue is not simply whether FICO remains widely used. It is how regulatory changes affect score volumes, pricing power, model adoption and the economics of mortgage credit reporting. The next FHFA policy announcement and the industry's response will be important indicators.
