Wall Street Now Values Google Search at 10 Times Earnings
Bank of America's analysts now value Google's core search business at about 10 times earnings, below the energy sector, after Alphabet's worst day on October 29. The reason is AI Mode: the first quarter in which AI visibly slowed search.
For two decades Google Search was the business investors paid a premium for. After Alphabet's 12.6% fall on Thursday, October 29, Bank of America's analysts calculated that the market now values it at about 10 times earnings. Justin Post and Nitin Bansal estimated that Alphabet as a whole trades at about 19 times 2027 earnings, down from 22 three months ago, and that once the cloud and other businesses are valued separately, the search core is priced at roughly 10 times, Fortune reported. The S&P 500 trades at 18.7 times forward earnings and the energy sector at 13.
The analysts' explanation fits in one sentence of their note: "Search AI transition will fuel the bears." Revenue from Google Search and other grew 12% in the third quarter, down from 17% in the second and 19% in the first, and InvestingLive reported that Google linked slower search advertising growth to greater use of AI Mode, the conversational version of search that answers questions directly. Pivotal Research's Jeffrey Wlodarczak said bears would argue that this was the first quarter in which AI seriously hurt the search business. Bank of America cut its price target to $380 from $430.
The mechanism is simple to describe and hard to measure. A traditional results page shows several paid links; an AI answer may show fewer, or none, and keep the user on the page instead of sending them to advertisers. Google has said AI Mode lets it show ads on queries it could not monetise before, and Philipp Schindler said on the call that ad experiments there had "shown promising results". JPMorgan's analysts, quoted by NBC News, called the slowdown in search "steeper than expected".
The shares closed at $283.82, erasing about $482 billion of market value, the largest one-day loss in Alphabet's history. What investors were pricing was a switch in roles: Google Cloud revenue more than doubled to $30.71 billion, but capital spending of $51.36 billion left free cash flow at minus $9.07 billion, so the business that used to fund Alphabet's bets now looks like the one most exposed to them.
A multiple of 10 is what the market usually pays for a business it expects to shrink, and that is the real claim embedded in Thursday's price. It can be tested every quarter: if search revenue growth stabilises while AI Mode usage keeps rising, the cannibalisation case weakens; if growth keeps falling by five points a quarter, the bears will say the 10 was generous.
