Amazon’s AI investments have driven the tech giant to new heights with earnings per share of $1.95, which is a big deal as it means that Wall Street expectations by 25%. The market responded swiftly. The company’s stock jumped 12% after announcing its impressive Q3 2025 results, and net sales grew 13% to $180.2 billion compared to last year.
Amazon’s cloud division shows AI’s massive impact on finance and investments. AWS sales in the third quarter grew 20% to $33 billion compared to the previous year, marking the strongest growth since 2022. AWS profits rose nearly 10% to $11.4 billion, making up three-fifths of Amazon’s total profit. The company’s confidence in its AI strategy became clear when it raised its capital expenditure forecast from $118 billion to about $125 billion for the year.
Amazon Reports Strong Q3 Earnings and Stock Jumps 12%
Amazon hit a remarkable milestone in the third quarter of 2025. The e-commerce leader delivered outstanding financial results that beat market expectations by a lot. Their investments in artificial intelligence are paying off well.
EPS beats Wall Street expectations
Amazon earned $1.55 per share, which beat analyst projections of $1.25 by a wide margin. This shows a 33% jump from last year’s numbers. The company’s net income reached $7.86 billion this quarter – more than triple the $2.30 billion from Q3 2022. The company has now beaten analyst estimates for five quarters straight, with the latest results 25% above forecasts.
Andy Jassy, Amazon CEO, shared his excitement about the results: “We had a strong third quarter as our cost to serve and speed of delivery in our Stores business took another step forward, our AWS growth continued to stabilize, our Advertising revenue grew robustly, and overall operating income and free cash flow rose significantly”.
Revenue climbs 13% year-over-year
The company pulled in $143.11 billion in total revenue, easily beating the $141.20 billion analysts expected. Sales grew 13% compared to last year – the best growth rate since Q4 2023. Here’s how different segments performed:
- North America brought in $69.81 billion, up 11% from last year
- International markets generated $32.48 billion, up 14% (10% in constant currency)
- Online stores made $53.53 billion, a 10% increase
- Third-party seller services reached $33.75 billion, up 12%
Operating income jumped to $17.23 billion, well above the guidance range of $12.31-20.5 billion. Prime Day 2025 broke records too. Prime members bought over 375 million items worldwide and saved more than $1.99 billion on various deals.
Stock reacts with double-digit surge
Amazon’s stock price shot up 12.4% to $198.54 on Nasdaq – an all-time high. Investors seem thrilled with Amazon’s artificial intelligence strategy in finance and investments, especially as competitors like Berkshire Hathaway ramp up their AI spending.
October gains reached 13% as the stock bounced back 53% from April’s low of $128.16. Amazon stock is heading for its third straight yearly gain, up 13% this year. This success stands out compared to other tech giants – Alphabet and Meta saw their shares drop even after beating expectations earlier this week.
The company expects a strong fourth quarter ahead. Sales projections range between $127.07 billion and $132.62 billion. The midpoint ($129.85 billion) would mean 9.6% growth from last year’s $118.49 billion. These projections, combined with stellar Q3 results, have renewed investor confidence in Amazon’s leadership position in e-commerce and cloud computing sectors.
AWS Growth Accelerates as AI Demand Surges

Amazon Web Services (AWS), the cloud computing division, has become the life-blood of Amazon’s artificial intelligence investments strategy. Many enterprises now just need AI-powered solutions, and AWS showed remarkable performance in Q3 2025.
AWS revenue rises 20% to $33 billion
The cloud giant’s revenue jumped 20% year-over-year, with AWS generating $26.21 billion for the quarter. This acceleration marks AWS’s fastest growth rate since early 2023. Enterprise cloud spending has clearly rebounded after several quarters of moderation. The division substantially outperformed analyst expectations of $25.75 billion. Businesses continue to move their critical operations to the cloud.
Andy Jassy, Amazon’s CEO, emphasized during the earnings call that AWS is “growing at a pace we haven’t seen since 2022”. This renewed momentum mirrors broader industry trends. Microsoft Azure and Google Cloud also reported strong growth during the same period.
AI workloads drive infrastructure expansion
AWS’s resurgence stems from a massive infrastructure buildout that supports the exploding demand for artificial intelligence workloads. Amazon has added more than 3.8 gigawatts of capacity in the last 12 months. This addition outpaces all other cloud providers’ infrastructure expansion.
Project Rainier stands at the center of this expansion. This groundbreaking project features nearly half a million Trainium2 chips, making it one of the world’s largest AI compute clusters. Teams completed the deployment across multiple data centers in Mississippi and Indiana in less than one year after its announcement. AWS keeps growing globally by adding a new Region in New Zealand and planning 10 additional Availability Zones.
Dave Brown, AWS vice president of compute and machine learning, reinforced their steadfast dedication: “We’re going to keep scaling for many years to come”. AWS plans to invest $8.74 billion in Georgia to build advanced cloud infrastructure specifically designed for AI workloads.
Trainium chip deployment boosts performance
Custom-designed Trainium chips power Amazon’s artificial intelligence investments strategy. These chips are built specifically for AI training and inference. First-generation Trainium chips powered Amazon EC2 Trn1 instances and delivered up to 50% lower training costs than comparable Amazon EC2 instances.
The newer Trainium2 chips deliver even better capabilities:
- Up to 4x the performance of first-generation Trainium
- 30-40% better price performance than current GPU-based EC2 instances
- Each chip can complete trillions of calculations per second
Amazon has ramped up these chips’ deployment rapidly. Anthropic now uses 500,000 Trainium2 chips for its Claude AI models. The partnership will expand to more than 1 million Trainium2 chips by the end of 2025. This expansion represents a multibillion-dollar revenue chance for AWS.
AWS accounts for majority of Amazon’s profit
AWS makes up about 15% of Amazon’s total revenue and remains the company’s main profit engine. The division generated $9.05 billion in operating income in Q3, about two-thirds of Amazon’s total operating profit. This profit strength continues even as Amazon invests heavily in expanding its AI infrastructure.
The division’s operating margin grew to over 30%, reaching its widest point in two years. Job cuts, slower hiring, and better cost control in non-people categories including infrastructure costs contributed to this growth. AWS successfully balances its aggressive artificial intelligence investments while maintaining strong profitability.
Amazon’s focus on custom AI chips challenges NVIDIA’s dominance in the AI chip market directly. NVIDIA remains the first choice for most customers starting their AI journey. However, Amazon positions its Trainium chips as a competitive alternative for specific workloads.
Amazon Increases AI-Driven Capital Expenditure

Amazon has made a bold strategic move by expanding its AI investments, dedicating unprecedented resources to build next-generation computing infrastructure.
Capex raised to $125 billion for 2025
Amazon’s capital expenditure forecast now stands at $99.27 billion (approximately $125 billion USD) for 2025, up from its earlier estimate of $93.71 billion. This is a big deal as it means that the $65.92 billion spent last year. The company has already allocated $71.39 billion through the first three quarters of 2025, and we directed most of it toward AI projects. Brian Olsavsky, Amazon’s CFO, expects this trend to continue and says capital spending will be “higher next year”. Andy Jassy, Amazon’s CEO, sees this massive investment as a “once-in-a-lifetime type of business opportunity”.
Project Rainier and data center expansion
Project Rainier leads Amazon’s AI infrastructure development with an $8.74 billion initiative that became fully operational less than one year after its announcement. The project now features nearly 500,000 Trainium2 chips, making it one of the world’s largest AI compute clusters. Built specifically for Anthropic to develop and deploy its Claude AI model, this infrastructure will grow to more than 1 million Trainium2 chips by the end of 2025. The complete site will eventually encompass 30 buildings and use 2.2 gigawatts of electricity—enough to power 1.6 million homes.
Amazon has committed $15.88 billion from 2025 to 2029 to expand data center infrastructure in Australia. The company has also pledged $15.88 billion in Pennsylvania, making it one of the largest single-state deployments in U.S. history.
AI infrastructure powers long-term growth
These AI investments set Amazon up for sustainable long-term growth. The company supports its expanded cloud infrastructure by investing in renewable energy, including three new solar farms in Victoria and Queensland. Companies that move their compute-heavy AI workloads to AWS can reduce carbon emissions by up to 94% compared to on-premises data centers. The company also extends its hyperscale infrastructure strategy to include resilient workforce development programs, such as the AWS Information Infrastructure Pre-Apprenticeship.
Comparison with Berkshire Hathaway artificial intelligence investments
Warren Buffett’s more measured approach stands nowhere near Amazon’s aggressive AI investments. Berkshire Hathaway’s position in Amazon is worth approximately $1.59 billion, yet this makes up less than 1% of Berkshire’s total portfolio. Buffett’s investment, which began in early 2019, recognizes AWS as the company’s AI strategy cornerstone. AWS runs powerful data centers equipped with advanced chips from suppliers like Nvidia, which it leases to businesses deploying AI software. This infrastructure-heavy approach differs from Berkshire’s traditionally conservative investment philosophy but shows how even value investors see AI’s transformative potential in finance and investments.
Retail and Advertising Segments Show Resilience

Amazon’s investments in artificial intelligence have created waves across its ecosystem, affecting cloud computing, retail, and advertising businesses.
Retail sales grow in North America and internationally
Amazon’s retail business showed strong results in Q3. North America sales jumped 11% year-over-year to GBP 84.42 billion, which beat analyst expectations of GBP 83.39 billion. International sales grew 14% to GBP 32.48 billion, showing a 10% increase without currency fluctuations. The company expanded its fast delivery services into rural areas, which helped sustain this growth. GlobalData MD Neil Saunders noted, “The clear win for Amazon this quarter is that it has managed to keep the elevated momentum of the last reporting period”. Everyday Essentials sales doubled the overall business growth year-to-date. Prime Day broke all previous records.
Ad revenue jumps 22% to $17.7 billion
Ad services proved to be a star performer as revenue climbed 22% in constant currency to GBP 14.06 billion. These numbers show faster growth than previous quarters and outshine the e-commerce division’s performance. Amazon’s ad growth beat Google’s 9% and came close to Facebook’s 23% growth rate. The company credits its success to a full-funnel ad strategy and demand side platform (DSP). Advertisers can now buy inventory across major streaming platforms.
Prime Video ads and e-commerce synergy
Prime Video is a vital part of Amazon’s advertising ecosystem. The service drew 15.1 million viewers for the Thursday Night Football season opener, making it Prime Video’s most-watched TNF game. TNF averaged 12.9 million viewers through the first six games, showing a 25% increase from last season. This growing audience creates new opportunities for advertisers. Jassy pointed out, “Live sports got a lot of interest from advertisers in upfront negotiations for 2025-26”.
AI improves targeting and customer experience
Amazon uses AI to optimize its advertising platform. The company launched generative AI capabilities to help sellers create product listings. More than 1.3 million independent sellers now use these tools. Amazon also introduced “an agentic AI tool and creative studio that plans and executes the entire creative process in a matter of hours instead of weeks”. These new tools make campaigns more effective, with modeled audiences showing up to 25% better engagement rates and 12% lower cost per click.
Analysts React to Results and Raise Forecasts
Wall Street analysts rushed to update their projections after Amazon’s remarkable Q3 results. Major firms pushed their price targets higher as they gained confidence in the company’s artificial intelligence investments strategy.
Morgan Stanley raises price target to $315
Morgan Stanley pushed its price target on Amazon to GBP 250.16 from GBP 238.25 while keeping an “Overweight” rating. AWS acceleration emerged as the main driver, with four factors pointing to faster growth ahead. These include near-term capacity expansion, plans to double gigawatt capacity within two years, a surging backlog, and state-of-the-art developments. The firm also raised its FY26 and FY27 EPS estimates by 5% and 6%.
Morningstar updates fair value estimate to $260
Morningstar adjusted its fair value estimate to GBP 194.57 per share from GBP 190.60. This change came after Morningstar reassessed Amazon’s growth potential, despite earlier lowered estimates based on previous results. The stock traded down initially, but Morningstar’s analysts called this “an overreaction” and stated that shares still “look attractive”.
Investor sentiment improves post-earnings
Amazon shares jumped 11% to a record high right after the results. This dramatic upturn led Zacks Investment Research to declare Amazon is “firing on all cylinders after a year of relative underperformance”. Wedbush analysts kept their GBP 222.36 price target and predicted a “breakout in 2026”. UBS shared this optimism by lifting its price target to GBP 221.57 from GBP 215.22.
Warren Buffett artificial intelligence investments comparison
Warren Buffett’s artificial intelligence investments approach through Berkshire Hathaway is very different from Amazon’s aggressive strategy. Berkshire has a modest position in Amazon, worth about GBP 1.59 billion – less than 1% of Buffett’s total portfolio. Of course, this careful approach stands in stark contrast to Amazon’s full-scale commitment to artificial intelligence infrastructure development.
Conclusion
Amazon knocked it out of the park with their Q3 results. The tech giant’s bold AI investments paid off big time, as shown by their stock jumping 12% after the earnings announcement. AWS emerged as their biggest success story. The cloud division grew 20% – its best performance since 2022. AWS now makes up about two-thirds of Amazon’s operating profit, proving their aggressive AI strategy was spot on.
The company plans to boost their capital spending to $125 billion by 2025, way above what they initially planned. Project Rainier shows their commitment to AI. They built one of the world’s largest AI compute clusters with almost 500,000 Trainium2 chips. This strong infrastructure sets Amazon up to lead the AI race for years to come.
AI benefits show up across Amazon’s business lines. Their North American retail grew 11% while international sales jumped 14%. Ad revenue shot up by 22%. These numbers show Amazon’s momentum in businesses of all types.
Wall Street loved the results. Morgan Stanley raised its price target to $315, pointing to AWS’s faster growth as the main reason. Morningstar and UBS also pushed their estimates higher.
Amazon’s Q3 2025 results confirm their massive AI investments were worth it. More growth seems likely ahead. While companies like Berkshire Hathaway take a slower approach to AI, Amazon’s all-in strategy works really well. They’ve changed from just an e-commerce leader to an AI powerhouse, raising the bar for the whole tech industry.
