Opendoor Technologies Inc (OPEN) shares plummeted 5.04% during intraday trading on Wednesday, reflecting significant downward pressure on the stock.

The decline appears linked to rising mortgage rates which are dampening housing market activity. Recent data shows the average rate on a 30-year fixed mortgage rose to 6.30%, reaching its highest level since late 2025. This increase has hit refinancing demand hard, with applications falling 19% from the prior week, while overall mortgage application volume has declined.

For Opendoor, whose business model is closely tied to housing turnover and transaction speed, higher borrowing costs can reduce affordability for buyers and decrease the incentive for homeowners to move, potentially weighing on the company's core transaction activity.
