The investment question

You now know MSFT reports about 13× SMCI's revenue, and MSFT keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to artificial intelligence, including “Azure and other cloud services consumption, including AI services” at MSFT, and which evidence in the next filings would prove that assumption wrong.

SEC filing comparison and disclosure evidence

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end June 30, so annual reports line up, but check segment definitions before comparing growth or margins.

The current verified House and Senate snapshot contains 204 matched transaction rows for MSFT and 11 matched transaction rows for SMCI. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you

This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.

A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
