An IXPE quick-response target of opportunity was approved and executed to observe the Gamma-Ray Burst GRB 221009A, detected by Fermi-GBM on 10/9/22. As the x-ray brightest afterglow recorded, numerous observatories are studying its properties and evolution. Quick-look analysis of the low-level instrument data set a preliminary 99%-confidence upper limit of 11% polarization, with a complete analysis of the processed data products to follow.
