Housing policy, trading frenzy, and a sharp analyst downgrade collide in this high-stakes real estate tech story, today, Jan. 9, 2026.

Opendoor Technologies (OPEN +13.45%), an online home-buying platform, closed Friday at $7.29, up 13.37%. Opendoor Technologies IPO’ed in 2020 and has fallen 33% since going public. Trading volume reached 165.2 million shares, about 64% above its three-month average of 101 million shares.

Friday’s catalyst was President Donald Trump’s $200 billion U.S. mortgage bond purchase plan, and investors are now watching how lower mortgage rates could support housing activity.
