FICO Shares Plunge in Worst Daily Drop Since 2022 as Mortgage Monopoly Ends
Key Facts
1Fair Isaac Corp shares are heading for their worst single-day decline in over two years following moves to end its mortgage scoring monopoly.
Fair Isaac Corp shares recorded their worst single-day decline in over two years on September 29, 2026. The Federal Housing Finance Agency (FHFA) announced a unified mortgage pricing grid placing VantageScore on equal footing with FICO, effectively ending the company's credit scoring monopoly according to Schaeffers Research.
TransUnion committed to maintaining low VantageScore pricing through 2028, intensifying downward pressure on FICO shares as it became one of the session's bottom performers. These structural changes aim to break the company's long-standing dominance in the US mortgage pricing sector and impact its historical competitive moat.
