This week brings a key test for major tech players as four industry giants announce their Q2 earnings, aiming to prove whether hefty investments in AI technology are generating tangible profits.

Microsoft and Meta both report on Wednesday in what analysts expect to be a defining moment. Microsoft is predicted to increase its capital expenditure forecast for 2026 to around $238 billion, signaling a push to balance spending discipline with rising costs in memory chips. On the other hand, Meta faces mounting investor skepticism after some capital shifted toward Google, especially as Alphabet’s cloud business saw an 82% surge last quarter a benchmark Wall Street now expects Meta to approach.

Thursday marks Apple’s final earnings call with Tim Cook at the helm. MarketBeat projects revenue near $108.9 billion. Apple’s strategy of maintaining lighter AI spending has kept it relatively shielded from the heavy expenditure challenges facing its competitors. The company’s stock recently hit an all-time closing high of $333, boosted in part by rising memory prices that have pressured competing smartphone makers.

Earlier in the week, SK Hynix reports its first earnings since debuting on Nasdaq at a record valuation. According to Yonhap Infomax, sales might reach 84.1 trillion won, potentially setting a new operating profit record despite the stock’s recent volatility and the Korean KOSPI index climbing past 7,000.

Adding complexity to this volatile earnings week is the Federal Reserve’s expected interest rate decision on Wednesday. Meanwhile, oil prices, which briefly climbed above $100 a barrel amid Middle East tensions before dropping more than 7% as hostilities eased, are influencing market sentiment and investor calculations.
