BlackBerry is effectively a bet on QNX, which holds the safety-critical software layer of Physical AI. QNX has about 38% of the global auto OS market, in over 275M vehicles; Q4 revenue rose 20% to $78.7M and its royalty backlog reached $950M. Integration with Nvidia's IGX Thor extends it into robots, medical and industrial systems, where years-long safety certification makes it hard to replace. Its other businesses grow slowly, so a QNX slowdown would leave no second engine. x.com
