RTB House survey shows consumers warming to agentic AI shopping

A new survey from RTB House found that 42% of U.S. millennials would let AI agents make purchases up to $250 with return protection, while 44% of consumers trust AI tools for shopping decisions. Commerce teams must recognize that agentic AI is shifting how customers discover brands and make purchase decisions, with the U.S. agentic commerce market projected to reach $1 trillion by 2030.

Consumer adoption of agentic AI shopping is accelerating, according to a survey of over 1,800 customers by performance marketing firm RTB House. Forty-two percent of U.S. millennials said they would allow AI agents to buy items on their behalf within a $250 budget if they could return purchases within seven days; without that safeguard, about a third would permit such purchases (Retail Dive - Technology). Additionally, 59% of U.S. consumers credit AI platforms with highlighting brands they didn't know, and 62% have relied on AI tools to compare prices, brands, models and reviews (Retail Dive - Technology).

Despite openness to agentic purchasing, consumers still prefer human oversight. Over a third (35%) of survey respondents said they would prefer a human to review transactions before AI agents make purchases, rising to 44% for baby boomers (Retail Dive - Technology). AI has surpassed traditional information sources in trustworthiness, with 44% of consumers trusting AI tools compared to 59% who trust friends and family, outpacing influencers, newspapers, and social media platforms (Retail Dive - Technology). In the U.S., Google AI Overviews and ChatGPT lead at 43% each, followed by Claude (23%) and Grok (21%) (Retail Dive - Technology).

The agentic commerce market is poised for explosive growth. By 2030, the U.S. agentic commerce market is projected to reach $1 trillion (Retail Dive - Technology), and 68% of survey respondents said they had used at least one AI platform in the past three months to shop. Amazon's Alexa for Shopping saw interactions skyrocket fivefold year-over-year, with more than 350 million customers using it in the past year, signaling that retailers are investing heavily in their own agentic AI tools (Retail Dive - Technology).
