Last week was a bust for initial public offerings (IPOs), with all three scheduled deals either postponing or withdrawing as market activity cratered later in the week. However, new filing activity picked up pace for an anticipated December blow-out, led by long-awaited delivery service unicorn DoorDash. Notably, Airbnb did not disclose its IPO filing last week as expected, but the home rental company still remains on track to go public in December.
