Fair Isaac Corp. shares plunge 21% as Bill Pulte orders end to FICO’s credit scoring monopoly

FICO’s decades-long grip on the credit scoring market just got pried open. Fair Isaac Corp. shares cratered as much as 20.9% intraday on September 4, falling to around $885, after Federal Housing Finance Agency Director Bill Pulte ordered Fannie Mae and Freddie Mac to immediately approve VantageScore 4.0 for all lenders.

The directive transforms what had been a small pilot program with roughly 50 lenders into a sweeping mandate that could fundamentally alter how American mortgages get underwritten. Pulte, never one to mince words, put it bluntly on social media: “FICO has enjoyed a monopoly. No more.”

What Pulte is actually doing

The FHFA directive does two things simultaneously. First, it forces the two government-sponsored enterprises that backstop the majority of US mortgages to accept VantageScore 4.0 alongside FICO scores from all lenders, not just a handpicked group of 50. Second, it puts a spotlight on what Pulte characterizes as runaway pricing in the credit reporting industry.

VantageScore 4.0 is jointly owned by Equifax, Experian, and TransUnion, the three major credit bureaus. Unlike traditional FICO models, it incorporates rental and utility payment histories into its calculations. That’s a meaningful difference for the roughly 26 million Americans who are “credit invisible,” meaning they have too thin a file for conventional scoring.

Pulte has been building toward this moment for months. His past statements flagged that per-score costs for credit reporting had surged by as much as 1,800% since 2020. In 2026 alone, average credit report costs rose by 40-50%, according to his public remarks. His position is straightforward: credit bureaus have been overcharging Americans for too long, and competition is the fix.

The market fallout

FICO wasn’t the only stock caught in the blast radius. TransUnion also tumbled on the news, though FICO bore the brunt of the selling. A 21% single-day decline for a company that had been trading above $1,100 earlier this year represents a destruction of billions in market capitalization.

The math behind the fear is simple. FICO’s business model relies heavily on scoring fees collected every time a lender pulls a credit score for a mortgage application. If VantageScore captures even a modest share of that volume, FICO’s revenue per mortgage origination drops. If VantageScore competes on price, which is the entire point of Pulte’s intervention, FICO faces margin compression whether it loses market share or not.

Why this matters beyond Wall Street

VantageScore’s inclusion of rental and utility payments could meaningfully expand mortgage eligibility. Someone who pays rent on time every month for a decade but has never carried a credit card balance might finally get scored in a way that reflects their actual reliability as a borrower.

For the mortgage industry, the transition introduces operational complexity. Lenders will need to decide which score to pull, or whether to pull both, and how to calibrate their underwriting models for a scoring system with different distributions and risk characteristics. FICO and VantageScore don’t produce identical results for the same borrower, and the divergence can be meaningful at the margins where approval decisions get made.

Investors watching FICO’s next few quarters should pay close attention to two metrics: the company’s average revenue per score and the volume of scores sold into the mortgage channel.
