Bill Ackman's post sends FNMA stock soaring

Federal National Mortgage Association (FNMA) shares are soaring on Mar 30 after billionaire Bill Ackman dubbed the housing-finance giant “stupidly cheap” in a social media post.

This high-profile endorsement triggered a huge wave of buying pressure, causing Fannie Mae and its sibling, Freddie Mac, to jump more than 30% on Monday morning.

Ackman’s stamp of approval brings much-needed reprieve to a government-backed enterprise that has otherwise struggled to maintain its momentum in 2026.

At the time of writing, FNMA stock is still down some 45% versus its year-to-date high.

Significance of Ackman’s Remarks for Fannie Mae stock

Fannie Mae shares pushed aggressively to the upside this morning primarily because Bill Ackman described their current valuation as “asymmetry at its best.”

According to the billionaire investor, FNMA could realistically see a tenfold increase, signaling to the market that risk-reward in this mortgage giant is currently skewed heavily to the upside.

Importantly, Ackman isn’t alone among famed investors in treating these federal housing-finance firms as undervalued titans.

Notably, “Big Short” investor Michael Burry has also expressed a bullish stance, recently making a sizable wager on the GSEs.

Burry’s involvement adds further weight to the bull case, as his historical expertise in the housing market suggests the current disconnect between FNMA’s earnings power and its suppressed stock price may be a rare buying opportunity.

Why else are FNMA shares attractive in 2026

A significant driver of the constructive sentiment in “Over-the-Counter” FNMA shares is ongoing speculation regarding the mortgage giant’s exit from government conservatorship.

For more than 17 years, Fannie and Freddie have operated under the thumb of the Federal Housing Finance Agency (FHFA), but recent reports suggest the Trump administration may now be nearing a deal to privatize them.

Such an exit will likely involve a initial public offering (IPO) or a secondary offering to recapitalize the titans, enabling them to retain billions in profits rather than sweeping them to the Treasury.

According to analysts, once the “senior preferred” stock overhang is resolved and these GSEs are allowed to operate as private utilities, an NYSE relisting could unlock a massive valuation multiple that Ackman and Burry are currently anticipating.

Bill Ackman says quality is finally on sale this year

While the spotlight remained on mortgage giants, Bill Ackman’s bullish stance extends far beyond the housing sector.

The Pershing Square founder emphasized that Fannie Mae and Freddie Mac are merely symptoms of a broader market disconnect – where some of the “highest quality businesses in the world” are currently trading at steep discounts.

Ackman characterized the present environment as “one of the most attractive” windows for long-term investors in years, suggesting that “quality” is finally on sale.

In short, by framing the GSEs as part of a larger basket of undervalued titans, Ackman is signaling a shift toward high-conviction value plays.

For investors, this broader macro view reinforces the idea that the rally in Fannie Mae stock isn’t just a speculative bubble, but part of a wider recalibration of value in a market that is beginning to reward durable, cash-flow-heavy enterprises once again.
