The term "$open stock warrant" likely refers to the special dividend of tradable warrants that Opendoor Technologies Inc. (OPEN) distributed to its shareholders. For every 30 shares of $OPEN held, shareholders received one warrant each of three different series (K, A, and Z) with different exercise prices of $9, $13, and $17 respectively. These warrants are now tradable on Nasdaq under the tickers OPENW, OPENL, and OPENZ, giving holders the right to purchase shares at the specified price before the warrants expire. 

 

Details of the warrant dividend

• Distribution: For every 30 shares of Opendoor common stock held as of the record date (November 18, 2025), shareholders received one warrant of each series: Series K, Series A, and Series Z.
• Exercise prices: Each series has a different, predetermined exercise price:
  • Series K: $9.00
  • Series A: $13.00
  • Series Z: $17.00
• Trading: The warrants are tradable on the Nasdaq stock exchange.
  • Series K: OPENW
  • Series A: OPENL
  • Series Z: OPENZ
• Exercise method: The company's warrant agreement allows for cash exercise, but the company has the discretion to implement a net exercise provision. 

 

What this means for shareholders

• Shareholders: Receive warrants for free, which can be sold on the open market for immediate cash or held for potential future gains if the stock price goes above the exercise price.
• Short sellers: May face increased costs, as they are now responsible for delivering these warrants to lenders of the shares they borrowed, potentially leading to a "cascade" of buying pressure as they exit their short positions.
