Yes, well the narrative that rocked the stock market is different. Its looking at what DeepSeek did and assuming they may have competitive advantage in this space and could outperform OpenAI at their own game.
If the narrative is actually that DeepSeek can only reach whatever heights OpenAI has already gotten to with some new tricks, then markets will probably refocus on OpenAI's innovations and price things accordingly, even if the initial cost is huge. It also means OpenAI probably needs a better moat to protect its interests.
I'm not sure where the reality is exactly, but market reactions so far have basically followed that initial narrative and now the rebuttal.
