Shares of Fair Isaac Corporation plunged 10.7% to $999 on September 4 after FHFA Director Bill Pulte ordered Fannie Mae and Freddie Mac to immediately approve all mortgage lenders for VantageScore 4.0, escalating what was already the biggest competitive threat FICO has faced in three decades. The broader market held steady, making this a company-specific blow.

• A Government-Granted Monopoly Faces Government-Driven Competition

FICO's dominance wasn't built on innovation alone — it was cemented by a regulatory framework that for nearly 30 years required lenders selling to government-backed mortgage buyers to use FICO scores exclusively. That era is ending. Fannie Mae and Freddie Mac are now accepting VantageScore 4.0 from all approved lenders, effective immediately, completing the full implementation of the 2018 Credit Score Competition Law. VantageScore is owned by the three big credit bureaus — Equifax, Experian, and TransUnion — giving it built-in distribution muscle.

• Aggressive Pricing Made FICO a Target

Over the past five years, FICO raised its per-score wholesale royalty for mortgage originations from $0.60 to $10.00 — a sixteen-fold increase, including a doubling from $4.95 to $10.00 for 2026.

Senator Josh Hawley opened an investigation in March 2026, urging the FTC and DOJ to examine whether those hikes constitute monopoly pricing. Meanwhile, Equifax is offering VantageScore 4.0 at $4.50 — more than 50% below FICO's $10 price — and TransUnion is providing VantageScore free through 2026 to mortgage customers who already buy a FICO score.

• The Financial Stakes Are Enormous

FICO's Scores segment generated $475 million in Q2 revenue, up 60% year-over-year, with mortgage origination revenue surging 127%.

The Scores segment alone produced $1.17 billion at roughly 88% operating margins in fiscal 2025. Any meaningful share loss in mortgage scoring — where the margins are fattest — directly threatens the profit engine.

• Wall Street Is Losing Conviction, Not Just Patience

In early August, Wolfe Research downgraded FICO, citing real VantageScore competition, and shares fell roughly 7%.

With the stock now down roughly 50% from its 52-week high, the question is whether the VantageScore threat justifies erasing half the company's value. FICO's own newer model, Score 10T, hasn't yet launched for mortgage use, and an adopter program already covers 70 lenders and 55% of top-50 originator volume — but time is no longer on the company's side. The regulatory wind has shifted, and today's selloff shows the market is pricing that in.
