Microsoft and Alphabet Diverge as AI Spending Rewards Differ

Microsoft and Alphabet both reported strong revenue, but investors reacted differently: Microsoft shares rose about 3% after hours, while Alphabet fell nearly 10% due to weaker earnings and higher planned AI spending. Microsoft beat revenue and earnings expectations, with Azure growing 43% and AI investments generating an estimated 30% return on invested capital. Alphabet narrowly beat revenue but missed earnings per share badly at $2.12 versus $3.02 expected, and its free cash flow turned negative in 2026. Alphabet’s capital expenditure is rising sharply, with more spending planned for 2027, while Microsoft’s heavy investment is already showing returns. Both companies depend on future AI payoffs, but Microsoft currently has stronger near-term momentum, trading near $550 resistance, while Alphabet faces a weaker technical position.
