Michael Burry, the investor known for his bet against subprime mortgages ahead of the 2008 financial crisis, has disclosed a new position in the preferred stock of Fannie Mae and Freddie Mac, according to a filing dated Oct. 10, 2026. The disclosure marks a notable shift in focus toward the two government-sponsored enterprises that have operated under federal conservatorship for more than a decade and a half.
In the filing, Burry framed the move around what he characterized as dilution risk in U.S. Treasury securities. The concern centers on the possibility that continued federal borrowing and the expansion of government liabilities could erode the value of existing Treasury holders’ claims. Preferred shares of Fannie and Freddie, by contrast, sit in a different part of the capital structure and carry their own set of risks and potential payoffs tied to the enterprises’ earnings and any eventual exit from conservatorship.
Why Fannie and Freddie Preferred Shares Draw Attention
Fannie Mae and Freddie Mac were placed into conservatorship by the Federal Housing Finance Agency in September 2008 as mortgage losses mounted during the housing crisis. Since then, the two enterprises have continued to guarantee and securitize a large share of U.S. residential mortgages, while their common and preferred shares have traded over the counter rather than on major exchanges. The preferred securities are particularly sensitive to any signal from Washington about the enterprises’ capital structure, dividend payments, or a potential release from government control.
Investors who hold the preferred shares have long debated how any restructuring would treat their claims relative to the Treasury’s senior preferred stake, which was established through the original bailout agreements. Changes to those arrangements, including adjustments to the dividend or liquidation preference, have historically moved the preferred prices sharply. The filing did not specify which series of preferred stock Burry purchased or the size of the position, leaving the precise structure of the trade unclear.
Dilution Concerns and the Broader Macro Picture
The dilution argument Burry is said to be making is not new. Fiscal hawks and some bond investors have periodically warned that sustained deficits and rising federal debt could pressure the value of outstanding Treasuries, whether through higher issuance, inflation, or changes to the terms of existing obligations. Treasury securities remain the benchmark safe asset for global markets, and any perceived erosion of that status would carry wide implications for interest rates, mortgage pricing, and the broader financial system.
For Fannie and Freddie, the investment case rests on a different set of variables: the trajectory of their guarantee fees, credit losses on the mortgages they back, and the political will in Washington to revisit conservatorship. The two enterprises have been profitable in recent years, which has kept attention on how those earnings are allocated between the Treasury and the companies’ own capital reserves. Any move toward recapitalization or release would be closely watched by holders of both common and preferred shares.
What to Watch
Market participants will look for further detail on the position, including the specific preferred series and any subsequent filings that clarify the size of the stake. Attention will also remain on any policy signals from the Federal Housing Finance Agency or the Treasury regarding the future of the conservatorship. For now, the disclosure places a prominent investor’s name behind a trade that depends on two distinct bets: skepticism about the long-term treatment of Treasury holders and optimism about the value of Fannie and Freddie’s junior capital.
