Several prominent funds run by investors like Ackman, Buffett, and Ken Griffin are holding heavy stakes in Alphabet. The article highlights that instead of taking risks on pure-play quantum stocks like IonQ or D-Wave, Alphabet offers exposure to the sector with less downside. Google's Quantum AI team had a breakthrough with their Willow processor last year. Along with the quantum exposure, the stock also includes their cloud division, Gemini AI, and Waymo. It seems to be a more stable way to invest in the technology without betting on highly speculative companies.
