Adyen‘s (AMS: ADYEN) latest Retail Report for the US unveils a surge in consumer trust for AI-driven shopping. Released this month, the report highlights how artificial intelligence is evolving from a mere recommendation tool to a full-fledged autonomous buyer, potentially reshaping the entire commerce landscape. The main finding is striking: over half (51%) of US consumers are willing to let AI handle their entire shopping process, including making the final purchase, once their preferences are set.

This marks a significant leap in adoption, with AI assistant usage more than doubling year-over-year from 12% to 35%.

Among those using AI, 66% report it saves time, while 62% appreciate how it cuts through online clutter and delivers proactive product recommendations.

Generational differences are evident—Millennials lead with 59% openness to AI purchases, followed by Gen X at 55%, Gen Z at 48%, and Baby Boomers trailing at 26%.

Shoppers’ priorities for trusting AI include optimizing for the lowest price and best value (45%), clear accountability for wrong purchases (45%), and transparency in product selection (41%).

Loyalty remains a cornerstone, with 59% of consumers more likely to engage with brands offering discounts or benefits.

Brand apps for checkout and loyalty points have seen 29% adoption overall, rising to 35% among Millennials and 33% for Gen Z.

On the retailer side, enthusiasm is high: 60% plan to boost AI investments in the coming year to improve customer experiences.

A whopping 88% are open to enabling AI to complete purchases on behalf of shoppers, with 56% marking it as a top strategic priority and 37% committing to investments within 12 months.

Key adoption factors include seamless system integration (38%) and robust data security (37%).

However, hurdles persist—31% of hesitant retailers fear AI’s unpredictable decisions leading to financial losses, and 27% worry about eroding direct customer relationships.

This trend signals a move from AI-assisted browsing to autonomous buying, but it raises questions about brand loyalty in an intermediary-driven world.

Trevor Nies, SVP and Global Head of Digital at Adyen, notes:

“We are starting to move beyond just the ‘browsing’ phase and entering into the ‘buying’ phase… This shift will fundamentally reshape how commerce operates.”  

Carlo Bruno, VP of Product at Adyen, adds:

“The biggest hurdle isn’t the technology, it’s the relationship.”  

The report recommends that retailers prioritize AI solutions that safeguard customer ties, integrate loyalty rewards, and enable direct upsell opportunities.

As payments infrastructure evolves, brands must balance responsible innovation with trust to thrive in this AI-enabled environment. With consumers increasingly delegating decisions, the future of retail lies in human-AI collaboration, ensuring efficient experiences for all participants.
