Federal Housing Finance Agency (FHFA) Expands VantageScore Use, Triggering Sharp Decline in FICO Shares
9/5/2026, 8:45:03 PM
Core Event
The directive expands a limited rollout that began on May 1, 2026, making the VantageScore model available to every mortgage lender originating loans for the two agencies. The announcement directly challenges the long-standing monopoly of Fair Isaac Corp.’s “Classic FICO” scoring model in the government-backed mortgage market.
Background & Context
The FHFA had previously allowed a restricted use of VantageScore 4.0 for a limited set of lenders starting May 1, 2026. By late August, VantageScore reported that the model accounted for more than 9 percent of mortgage securitizations for Fannie Mae and Freddie Mac. Prior to Pulte’s tenure, FHFA director Sandra L. Thompson had proposed a “bi-merge” framework that would combine VantageScore 4.0 with a newer FICO model (10T) and draw data from only two credit bureaus; that plan was placed on indefinite hold in January 2025. Pulte’s recent posts also referenced a possible “bi-merge” or “single-file” reporting requirement, suggesting further restructuring of the credit-reporting system.
Data & Statistics
- Fair Isaac Corp. (FICO) shares fell between 15 percent (afternoon session) and 21 percent (intraday low) after the announcement.
- Equifax and TransUnion each dropped up to 11 percent; Experian’s movement was not quantified.
- FICO’s stock is down 43.2 percent year-to-date, trading at $933.70, which is 50.3 percent below its 52-week high of $1,880 (recorded in October 2025).
- The VantageScore rollout has involved 50 lenders delivering loans under the new model.
- Pulte alleged that FICO’s per-person credit-score price has risen 1,800 percent since 2020.
- Mortgage-originations represent more than 60 percent of FICO’s total Scores-segment revenue, which rose 41 percent year-over-year in the most recent fiscal quarter.
Official Statements & Responses
- The FHFA, Fannie Mae, and Freddie Mac did not respond to requests for comment at press time.
Conflicting Reports & Gaps
- Share-price impact figures differ: Bloomberg reported a maximum intraday decline of 21 percent for FICO, TradingView noted a 15 percent drop, and The Globe and Mail cited a 15.2 percent decline in the afternoon session.
- No official comment was obtained from the FHFA, Fannie Mae, Freddie Mac, or the three credit bureaus (Equifax, Experian, TransUnion) regarding the immediate implementation or the potential bi-merge proposal.
- Details on how the proposed bi-merge model would integrate the newer FICO 10T score remain unclear.
What’s Next
The FHFA indicated that it is still evaluating “bi-merge” and “single-file” reporting options, which could further reduce reliance on the three-bureau tri-merge system. Industry observers anticipate that expanded VantageScore eligibility may intensify competition for mortgage-originator contracts and could prompt additional regulatory reviews of credit-scoring pricing practices. Future FHFA guidance or formal rulemaking on reporting structures will likely shape the competitive landscape for both VantageScore and Classic FICO models.
