How Fair Isaac (FICO) Is Deepening Its Mortgage Lending Moat Through Broader FICO Score 10T Adoption

Fair Isaac Corporation (NYSE:FICO) is one of the high-growth wide-moat stocks to buy. On June 4, FICO announced that Optimal Blue integrated FICO Score 10T into its capital-markets platform. The integration allows lenders to use the score for pricing, eligibility decisions, hedging, trading, and loan-portfolio valuation across the mortgage lifecycle. Optimal Blue said it supports about 60% of the top 50 U.S. mortgage lenders.

The development is relevant because it extends FICO Score 10T beyond a standalone credit metric and embeds it more deeply in lending infrastructure. A score that is integrated into pricing engines, secondary-market tools, and servicing workflows becomes harder to replace than one used only at loan origination. FICO also said Score 10T is available alongside its classic score through a free-access program, which gives lenders room to test it before wider implementation. The company faces regulatory scrutiny and competition from VantageScore, particularly in mortgage lending. Even so, FICO's long-standing position, lender familiarity, and broad adoption give it a structural advantage that is difficult to rebuild from scratch.
