Opendoor (OPEN): Unit Economics Arrive as Inventory Rebuilds

Opendoor is the listed cash-offer platform that buys and resells houses as principal, and the second-quarter print is the first clean look at whether the Opendoor 2.0 reset actually changed the machine. Kaz Nejatian, hired from Shopify in September 2025 with co-founders Keith Rabois and Eric Wu back on the board, spent three quarters shrinking the book, tightening spreads, and shipping product instead of buying demand with advertising. The investment debate is no longer whether the old iBuyer model survived the rate shock. It is whether a thinner, software-heavier version can rebuild volume inside a target contribution-margin band without reopening the inventory wound that nearly broke the company.

The operating evidence in the June quarter is the first time that volume and unit economics moved together rather than as substitutes. Management generated more than six thousand nine hundred acquisition contracts on $5 million of marketing. That compares with $81 million the last time contract volume cleared six thousand, which was the second quarter of 2022. Homes purchased rose seventy-seven percent sequentially to 4378, while contribution margin reached 5.8 percent. Combined marketing and operations cost per contract printed at the lowest level in company history. That pairing is the entire turnaround: demand earned by product rather than purchased by spend.

The income statement still refuses to celebrate. GAAP net loss widened to $162 million. Stock-based compensation and the inventory rebuild dominate reported earnings. Adjusted EBITDA only reached a $4 million loss. Shares last traded at $2.56, near the fifty-two-week floor. The stock sits far below the $9.69 high, for a market value near $2.5 billion. The August zero-coupon convertible and the September exit of Opendoor Home Loans from beta are the next tests of whether capital and adjacent attach rates support the rebuild. The question the next two quarters resolve is whether contribution margin holds as the book scales, or whether a frozen housing market forces another retreat.
