FICO GTFO

As if homebuyers don’t already have enough numbers to stress about, the credit score your lender actually cares about may be changing.

Fair Isaac, the company behind FICO scores, plunged 26.52% today after a months-long government effort to bring more competition to mortgage lending took another big step forward.

FICO’s moat got crowded

For decades, one name has dominated the mortgage credit-scoring business: FICO. If a lender wanted to originate a mortgage that could ultimately be sold to Fannie Mae or Freddie Mac, a FICO score was effectively part of the process. Every time that score was pulled, Fair Isaac got paid.

Now, that moat is eroding. Federal Housing Finance Agency (FHFA) Director Bill Pulte announced yesterday that Fannie Mae and Freddie Mac will move to a single mortgage-pricing grid that includes both Classic FICO and VantageScore, a credit score model developed by Equifax, Experian, and TransUnion as an alternative to FICO. The move puts the two scoring systems on more equal footing inside the conventional mortgage market.

Then, the other shoe dropped: Rocket Mortgage said it will make VantageScore 4.0 its preferred scoring model for eligible loans beginning this quarter. That gives investors their clearest sign yet that FICO’s new competition could translate into actual lost business, rather than just another regulatory headache.

It’s not just FICO

Equifax, TransUnion, and Experian, which helped create VantageScore, seem like they’d be big winners now that FICO is losing its competitive advantages. Instead, shares of all three fell today because regulators are also scrutinizing the broader credit-reporting business.

Pulte has accused Equifax, Experian, and TransUnion of overcharging consumers, and said the agency is considering a “bi-merge” system that could let mortgage lenders use reports from only two credit bureaus instead of three. That could reduce a recurring source of revenue for the bureaus, even if VantageScore itself gains market share.

So what does that mean for homebuyers? The truth is, the impact is modest.

VantageScore can weigh some borrowers differently than Classic FICO, potentially helping people with thinner traditional credit histories qualify for mortgages. More competition could also lower some of the costs lenders pay to check credit.

But scoring fees are still a small part of the affordability problem. Freddie Mac’s average 30-year mortgage rate reached 7.03% last week for the first time since early 2025. A new credit score won’t make an expensive mortgage cheap. But it could change who qualifies for one, while forcing some of the companies that have long charged lenders to assess borrowers to compete harder for the business.

As for Fair Isaac shareholders, they’ll have to wait and see whether other large lenders follow Rocket. Regulators have already created the alternative—the only question is how much mortgage volume actually moves away from FICO.—HC
