AI Finally Showed the ROI. Rates Raised the Price.
GOOD MORNING, Amazon gave Wall Street the AI proof point it had been waiting for. AWS grew 37%, Amazon raised its 2026 capex plan to about $220 billion and the stock surged as investors decided the spending was already producing measurable returns. But Friday also delivered the other side of the trade: the 10-year and 30-year Treasury yields climbed to multi-year highs, while Brent finished July up 24% as Hormuz disruptions persisted. AI earnings are getting stronger. The discount rate investors apply to them is getting harder too. MARKETS | TLDR
AI ROIAmazon Earned the Right to Keep SpendingAmazon's second-quarter results gave investors the clearest answer yet to the AI-capex question. AWS revenue grew 37%, its strongest pace in more than four years, while Amazon said both its AI business and internally designed chip business had surpassed a $25 billion annualized revenue run rate. The company also raised its 2026 capital-spending plan by 10% to about $220 billion. That matters because Big Tech's AI spending had become one of the market's biggest sources of anxiety. Investors were increasingly willing to penalize companies that raised capex without showing enough near-term revenue or margin payoff. Amazon broke that pattern. Faster AWS growth gave the market a visible link between the money going into data centers and the revenue coming out of them. The caveat is cash flow. Amazon's trailing 12-month free cash flow swung to a $7.6 billion burn from positive $18.2 billion a year earlier, meaning the company is still front-loading enormous infrastructure costs. CEO Andy Jassy argued that much of the capacity being built is already reserved through 2027 and partly into 2028. Friday's rally therefore did not end the ROI debate. It showed the standard investors are increasingly using: spend aggressively, but prove that customers are already there. DISCOUNT RATEAI Earnings Improved. The Bond Market Got Less Friendly.Long-term Treasury yields rose sharply Friday, with the 10-year reaching about 4.75% and the 30-year touching roughly 5.25%, both near multi-year highs. Several Fed officials argued that rates may need to rise again if inflation stays elevated, pushing markets toward a roughly 65% probability of a September hike. That matters because the same week that produced stronger AI revenue also raised the cost of valuing it. Higher long-term yields reduce the present value of future earnings and increase the borrowing cost for the data centers, power systems and networking equipment required to deliver those earnings. The AI trade can therefore improve fundamentally while becoming more expensive financially. Oil adds another layer. Brent finished July up 24% and WTI gained 21%, keeping inflation pressure alive through energy, freight and input costs. The market enters August with a cleaner AI monetization story but a less forgiving macro backdrop. The next leg of the rally may depend on whether earnings can keep accelerating faster than the discount rate. HEADLINES

DEEP INSIGTHSAmazon's AI Capex Is Producing Measurable ReturnsRead this for the clearest public-market example of what investors now want from AI spending: faster cloud growth, identifiable AI revenue and evidence that capacity is already reserved. The article also highlights the trade-off — Amazon is spending so aggressively that free cash flow has turned negative. Oil Ends July Up 24% as Hormuz Risk PersistsThis is useful for understanding why stronger AI earnings do not automatically translate into easier financial conditions. The same month that cloud growth accelerated also produced a major energy shock, keeping inflation and Treasury yields elevated and raising the hurdle rate for long-duration investments. |
