What are the margin requirements for an initial public offering (IPO)?

To hold shares of an IPO overnight, regulations governing IPOs state that new issues are non-marginable for a minimum of 30 days following pricing.

This means that IPO shares must be paid for using cash or cash available to borrow*.

For day trading purposes, margin requirements are determined by the clearing house the day of the IPO.
