The probability of the U.S. Department of Homeland Security (DHS) shutdown ending by March 31 has decreased to 54% on Polymarket, following the U.S. Senate's confirmation of Senator Marlin as Secretary of Homeland Security. This marks a 26% drop in the past hour, with trading volume approaching $1 million. Meanwhile, the odds for the shutdown ending between March 28 and 31 have risen to 24%, up 13% in the same period. Senator Marlin, during his nomination hearing, expressed support for the Trump administration's immigration policies and urged Democrats to pass the DHS budget bill to "reboot" the agency. The DHS has been shut down since February 14 due to funding issues, with Democrats demanding reforms before supporting the budget bill.
