Opendoor

Opendoor makes instant cash offers on homes using a valuation model trained on hundreds of property and market signals, letting sellers skip the traditional listing process and close on their own timeline. The iBuyer business model got hit hard once interest rates rose in 2022 and home price appreciation slowed, and Opendoor's stock became something of a meme-stock rollercoaster in 2025 — worth knowing that the underlying real-estate cycle has mattered as much to the company's fortunes as the AI valuation technology itself.
