Alphabet $80B Raise Signals AI Capex Entering Rational Phase

The latest development shows Alphabet launching an $80 billion equity offering to fund AI data-center expansion, raising concerns that hyperscaler spending may slow after a massive capex wave. This follows weeks of institutional rotations beginning May 17, with Whale Rock buying AI supply-chain names, Michael Platt exiting Nvidia for TSMC, Bill Ackman swapping Alphabet for Microsoft and Amazon, Tiger Global adding Nvidia shares, and Stanley Druckenmiller slashing Amazon 94% while initiating an Intel position. The pattern highlights selective profit-taking in mega-cap AI leaders alongside bets on semiconductor infrastructure, with Nvidia remaining the central reference point amid potential near-term spending caution.
