After a volatile week that saw all three major US stock indices end lower, investors are heading into what could be the most important trading week of the quarter. Four of the Magnificent Seven will report earnings, the Federal Reserve will announce its latest policy decision, while easing tensions in the Middle East have sent Brent crude back below the $100-a-barrel mark, removing one of the market's biggest short-term inflation risks.
The earnings spotlight now shifts to Microsoft and Meta on Wednesday, followed by Apple and Amazon on Thursday. After last week's sharp sell-off in Alphabet and Tesla, investors are no longer rewarding AI spending alone—they want evidence that billions of dollars in investment are translating into stronger earnings and cash flow.
Alphabet delivered better-than-expected revenue and profit, with Google Cloud revenue surging 82% year-on-year. Yet the company also raised its 2026 capital expenditure guidance to $195-205 billion, while free cash flow turned negative for the first time since listing. Tesla also reported negative free cash flow alongside rising capital spending, triggering a combined market-value loss of roughly $500 billion after earnings.

The market's message has become increasingly clear: AI spending is no longer enough—investors want returns.
The other major event this week is the Federal Reserve's July policy meeting. Markets still expect policymakers to leave interest rates unchanged, but expectations for further tightening have strengthened in recent weeks.
According to CME FedWatch, markets currently price a 63.7% probability that the Fed will hold rates steady this week, while the chance of a 25-basis-point hike has risen to 36.3%, up sharply from around 10% following the June CPI report earlier this month.

Recent data has complicated the policy outlook. The US labor market remains remarkably resilient, with initial jobless claims recently falling to their lowest level since 1969, while inflation remains well above the Fed's target despite softer monthly CPI and PPI readings. At the same time, elevated energy prices, renewed tariff measures and continued AI-driven investment have all added to concerns that inflation could prove more persistent.
Even if the Fed stays on hold this week, markets will be watching Chair Kevin Warsh's guidance closely for any signal that another rate hike could arrive as early as September.
With heavyweight earnings, a pivotal Fed meeting and shifting macro expectations all arriving within days, this week's market reaction may be driven less by headline results and more by what they reveal about the outlook for AI profitability, inflation and interest rates.
