The previous record holder was 2.2m bushels in Mason City, IA in 2021.

Janesville is the future site of the construction of what will be the world’s largest grain bin, with a capacity of 2.3 million bushels.

Projects like this aren’t just about size — they’re about performance. More capacity. Faster handling. Better efficiency. And infrastructure built to serve agriculture for decades to come.

We’re proud to be part of projects that help move the industry forward and support the producers and operations that depend on facilities like this every day.

This is what Building the Backbone of America looks like.

[Fortunately, some comments identify this Janesville as the one in MN.]

This looks like an ethanol plant. The 2021 record holder was also an ethanol plant. I presume that ethanol plants don't care how clean the corn is so they can store everything that comes to the plant in one bin.

2.3 million bu that’s 2,300 semi loads this is the largest grain bin in the world just outside of Janesville. This image was taken last night and the bin is not finished.

Brian Fuhrmann: I’s at Guardian Energy Ethanol. [This confirms that it is an ethanol plant.]

Brian Mittelstaedt: And the one behind it is a Million bu. Pretty good comparison
