Bank of America flags generative AI as a potential threat to Google’s next wave of ad revenue

Bank of America is drawing attention to a new competitive front for Alphabet’s Google advertising machine, according to commentary carried by Yahoo Finance. The bank’s view, as described in the report, is that ChatGPT-like generative AI systems may increasingly influence how people search, compare, and purchase, potentially taking away not just ad engagement but a future share of the ad dollars Google expects to monetize.

The underlying concern is that generative AI can change the user journey. Instead of starting with a list of links, users may ask a tool a question and receive a synthesized response. That shift, BofA’s framing suggests, could make it harder for traditional search-linked advertising formats to capture demand at the moment it is created.

For Google, the timing matters. Google’s ad business is often discussed in terms of near-term auction dynamics, but the report’s premise is about “next” ad dollars, implying that the competitive threat is directed at where budgets will go as AI-powered discovery becomes more common. If more buying activity moves upstream into AI-driven recommendation and explanation, ad placements that depend on standard search and browsing pathways may face incremental pressure.

Google has substantial infrastructure for advertising, including search ads and other placements across its properties. But generative AI introduces a different kind of intermediary. Rather than merely presenting results, AI systems can summarize and suggest, which changes the surface area available for ads. That does not eliminate advertising opportunities, but it can alter what counts as an “optimal” ad insertion point and how much inventory remains tied to classic query intent.

Sector context is also important. The race to commercialize generative AI has put pressure on incumbents to adapt product experiences, including how information is displayed and monetized. In Google’s case, any meaningful change in how users reach content or products can ripple through advertisers’ expectations for targeting and measurement, especially if AI responses shape which brands users consider.

The market news report does not provide additional specifics about what exact products or deployments BofA believes are most at risk, nor does it lay out numerical scenarios for Google’s revenue. It also does not indicate whether BofA expects an immediate impact or a longer-term reallocation of ad spend. As with many sell-side observations, the key details are likely to be in the assumptions behind the bank’s analysis, which were not included in the brief description.

What to watch next is whether Alphabet discloses any quantified commentary on AI-driven discovery and how it plans to preserve advertiser ROI in generative experiences. Investors will also look for whether rivals’ AI offerings demonstrate measurable effects on search behavior, traffic, or ad engagement, because that would help translate a strategic risk into observable market outcomes.
