Prime Day Starts Today. The Bigger Test Is Amazon's AI Shopping Bet.

With billions in sales expected over four days and a new AI shopping assistant front and center, Amazon is using its biggest retail event of the year to answer a question Wall Street actually cares about.

Prime Day Starts Today

Amazon's Prime Day kicked off this morning and runs through Thursday, June 26 β€” four days of discounts on electronics, household goods, and just about everything else. But beyond the deals, this year's event is an early real-world test of whether Amazon's AI shopping layer can lift conversion at scale. It is the first Prime Day since Amazon folded Rufus into the more prominent Alexa for Shopping experience, and the question investors are actually watching is whether artificial intelligence can get people to spend more.

The financial scale of the event is not in question. Bank of America estimates Prime Day will generate roughly $21.6 billion in gross merchandise volume, up about 5% from last year β€” though that comparison is somewhat favorable to 2025, whose 55% surge was inflated by the first year of the four-day format. Adobe, which tracks visits to retail sites, forecasts $26.3 billion in total US online spending across retailers during the four-day period, up 9% from last year's July event. That would make Prime Day week larger than Black Friday and Cyber Monday 2025 combined, which together drove just over $26 billion.

The real story: Alexa for Shopping

The star of this year's event is Alexa for Shopping, Amazon's upgraded AI assistant. Unlike a simple chatbot, it can take actions on a shopper's behalf: building personalized deal guides based on purchase history, setting price alerts, surfacing up to a year of price history for any product, and even auto-buying an item when it hits a target price. Amazon is using Prime Day, with its captive audience of tens of millions of bargain hunters, to introduce the tool to the broadest possible audience β€” betting that customers who try it now will stick with it and spend more over time.

The financial logic behind that bet is substantial. Bank of America analyst Justin Post, who rates Amazon a Buy with a $310 price target, believes Alexa for Shopping could eventually add more than $200 billion in gross merchandise volume and over $20 billion in retail profit by 2035. The thesis is that an effective AI assistant protects Amazon's direct traffic β€” keeping shoppers from starting their searches on Google or TikTok β€” lifts conversion rates, and nudges shoppers toward incremental purchases they might not otherwise make.

The early evidence comes from Rufus, the predecessor AI assistant that Alexa for Shopping now builds on. Amazon says more than 300 million customers used Rufus in 2025, and that shoppers who used it during a browsing session were more than 60% more likely to make a purchase. Those numbers underpin the optimism that a more capable, action-taking assistant could move the needle further on a platform of Amazon's scale.

The consumer backdrop

There is a broader consumer story here, and it is more cautious. Prime Day arrives as shoppers face elevated prices and tighter budgets. Adobe's own survey data found that spending intentions remain strong even as inflation concerns weighed on consumer sentiment heading into the event. That backdrop cuts both ways. Bargain hunters may be more motivated than ever to take advantage of deals β€” Adobe expects discounts of 12% to 23% across major categories. But stretched households may also simply buy less, AI assistant or not.

Adobe also expects buy now, pay later to account for about 7.8% of e-commerce spending during the event, up from last year β€” a signal worth watching. A higher-than-expected BNPL share would suggest shoppers are stretching to participate, which has different implications for sustained consumer demand than outright cash purchases.

The rival response is more intense than ever. Walmart and Best Buy launched competing sales on Monday, a day ahead of Prime Day, and Target is running overlapping promotions. Research from digital marketing agency Tinuiti found that nearly 60% of consumers planning to shop Prime Day will also browse Walmart's offers, and 35% plan to visit Target. Amazon remains dominant β€” eMarketer estimates it will capture roughly 60% of total US online spending during the Prime Day period, its largest share since 2019 β€” but the competition for the same consumer wallets is real and growing.

What to watch

  • Alexa for Shopping engagement: Amazon will not report real-time usage data, but watch for any company statements during or after the event about assistant adoption rates, interactions per session, or conversion lift. Those metrics are the leading indicator of whether the AI bet is working.
  • GMV vs. revenue: Bank of America estimates Prime Day will contribute roughly $8.5 billion in incremental Q2 revenue. Watch for whether Amazon's Q2 results, due in late July, confirm or exceed that figure β€” and whether management comments on AI-driven shopping behaviors.
  • Competitors' results: Walmart, Target, and Best Buy are all running simultaneous sales. How those events perform relative to Amazon will reveal whether Prime Day is growing the overall e-commerce pie or redistributing existing consumer spending.
  • BNPL usage: Adobe's $2.04 billion BNPL forecast for the event is a useful barometer of consumer financial health during what is supposed to be a spending boom. Watch whether the final number comes in above or below that estimate.

The bottom line

Prime Day has evolved from a simple sales event into a proving ground for the AI-powered future of shopping. The discounts will drive the headline numbers, but the real question for investors is subtler: can Amazon turn AI engagement into measurable, incremental spending at scale? If Alexa for Shopping delivers, it validates a multibillion-dollar bet and raises the long-term ceiling on Amazon's retail economics. If it falls flat with a cautious consumer, it is a reminder that even the best technology cannot conjure demand that is not there.

The deals are live. The experiment has started.
