Fair Isaac (NYSE: FICO) is down about 17%, to roughly $931, per Investing.com, with TheStreet clocking the intraday drop at 17.5%. Thursday's close was $1,118.93 (TradingView). No earnings, no guidance cut — the whole move came from one post by a regulator.

What happened

Late Thursday, FHFA Director Bill Pulte wrote on X: "Effective immediately, I'm instructing Fannie and Freddie to approve all lenders to use VantageScore." He added that "FICO has enjoyed a monopoly. No more." (Benzinga). Until Thursday, VantageScore inside the Fannie/Freddie system was a pilot of about 50 lenders. Now it's every lender. FHFA had already made VantageScore 4.0 and FICO Score 10T eligible models on 22 April 2026; Thursday removed the last gate.

Why it moved — the number that explains it

Here's what the headline misses. In fiscal Q3 2026, FICO's mortgage originations revenue grew 97% year-on-year — and the company's own slides say that came despite only modest volume increases (Investing.com). Mortgages weren't booming. FICO was charging far more per score.

Q3 revenue was $674m, up 26%; Scores alone was $459m, up 41%, of which B2B Scores was $400m, up 49%. Mortgage originations made up 71% of B2B Scores revenue and 62% of all Scores revenue (AskTraders) — roughly two-fifths of the whole company.

Now the prices. Since 1 January 2026, FICO's direct-licence programme charged $4.95 per score plus $33 per borrower on a funded loan, or about $10 per score through tri-merge resellers (HousingWire). In April, FICO cut the Score 10T upfront fee to $0.99 but lifted the funding fee from $33 to $65 — deliberately revenue-neutral. VantageScore 4.0 is $0.99 per mortgage origination score at Experian, with TransUnion matching. Pulte's claim: FICO's cost per score is up 1,800% since 2020.

So the market isn't marking down lost volume. It's marking down pricing power — the ability to double revenue on flat volumes. That's what a monopoly is worth, and that's what got repriced.

The business — what's actually exposed

• Scores — $459m, about 68% of Q3 revenue. B2B ($400m) covers mortgage, card, auto and personal-loan scores sold through the bureaus; a smaller consumer arm sells myFICO subscriptions direct.
• Software — $215m, up just 2%. FICO Platform, the decisioning and fraud software banks run. Platform revenue $102m, up 66%; legacy Non-Platform down 25% to $95m as customers migrate. Platform ARR passed Non-Platform for the first time: $413m vs $403m.

Mortgage scoring is the crown jewel, not the whole company. Card, auto and personal-loan scores and all of the software business sit outside Thursday's order.

Is it expensive?

At Thursday's close FICO carried a $23.75bn market cap and a trailing P/E of 31.8 on TTM EPS of $34.81 (TradingView). Today's fall pulls that to roughly 27x. In June, Simply Wall St had FICO at 34.8x versus a 26.1x software-industry average — so this is a premium multiple compressing toward the pack, not a bargain.

The peer comparison is the awkward part. Equifax — one of the three bureaus that jointly own VantageScore — trades near 33x trailing (20.6x forward) on a $22.2bn market cap and $6.44bn of revenue (StockAnalysis). FICO carries a similar market cap on FY26 revenue guided around $2.45bn — a third of Equifax's sales for the same price tag. That premium existed because FICO was a toll booth with software margins. The question now is what a toll booth is worth once a rival can charge 99 cents.

Who it touches

• Equifax, Experian, TransUnion — joint owners of VantageScore, and the direct beneficiaries of any switch.
• Lenders and borrowers — TransUnion has described FICO's fee structure as "a $99 penalty fee on each homebuyer ($198 for co-purchasing couples)" (HousingWire).
• Tri-merge resellers — FICO signed agreements covering about 60% of US mortgage volumes; those economics now face a cheaper alternative.
• India — no read-across. CIBIL, Experian, Equifax and CRIF High Mark price under RBI's own bureau framework, untouched by a US housing-agency directive.

What to watch

Permission is not payment, and that's the strongest case against today's move. Typef Capital's research notes VantageScore already climbed from under 5% to nearly 30% of TransUnion's mortgage inquiries by Q2 2026, across more than 900 lenders — while FICO's mortgage revenue grew 97% anyway. The reason is unglamorous: lenders pull the free VantageScore alongside a paid FICO to improve a borrower's qualification odds. Almost nobody buys it as a replacement.

The order changes the rulebook, not the plumbing — underwriting engines, MBS investors and servicers are still wired to FICO. So one dull data point settles it: mortgage originations revenue in the next quarterly report. Holds up while VantageScore usage climbs, and today was a repricing of risk. Rolls over, and the monopoly really did end on a Thursday night post.
