Rocket Mortgage's Shift to VantageScore Triggers 26% Plunge in FICO Shares
Rocket Mortgage announced it will adopt VantageScore 4.0 as its primary credit scoring model for eligible loans, marking the first major departure from the FICO standard in the mortgage sector. This move, following four months of testing, aims to lower costs and expand access for borrowers with limited credit histories. The announcement triggered a 26.5% drop in Fair Isaac Corporation (FICO) shares on September 30, 2026, as investors reacted to the potential erosion of FICO's market dominance.
