You can download the daily stock prices of AI stocks at Nasdaq.com. The AI market is much too large and complex to be manipulated by anyone.

I never said AI can be manipulated, but the stock market can be manipulated by AI. Blackrock makes money on the margins. They only need to push a stock up or down by a small bit to make a lot of money and they can do that continuously.
The average person cannot use AI to the same point that the giant venture firms can. The average person is almost helpless on that point.
