Opendoor is the market’s latest Meme Stock w/insane trading volumes. Shares of the San Francisco-based tech group that focuses on the stagnant real estate sector have nearly tripled in value over the past week. The rally appears to have been sparked by a prominent investor discussing the stock on social media, which drew the attention of retail traders. The company has struggled since peaking at a $20.6bn valuation in February 2021, shortly after merging with the SPAC (special purpose acquisition company) Social Capital Hedosophia Holdings Corp II, led by Chamath Palihapitiya. That decline isn’t surprising: Opendoor’s core business is in the "instant buyer" market, where it aims to make home sales faster and bypass traditional realtor fees—an idea that has faced serious challenges in a cooling housing market.
