Opendoor Technologies Inc. (Nasdaq: OPEN) completed its public debut through a merger with Social Capital Hedosophia Holdings Corp. II, a special purpose acquisition company sponsored by Chamath Palihapitiya's Social Capital. The SPAC filed its final prospectus on Form 424B4 in April 2020, marking the blank-check company's IPO before its merger target was identified. The de-SPAC transaction with Opendoor, an online residential real estate marketplace operating in the iBuying and proptech sector, closed in December 2020, with shares trading under the ticker OPEN on Nasdaq. The company remains active in the digital home-buying space, where it operates as one of the most prominent post-SPAC proptech names.
