Microsoft's market value tops $500B for the first time since 2000, after its Q2 earnings beat analyst expectations

Context & Ripple Effects
In January 2017 Microsoft crossed $500B in market value for the first time since the dot-com peak, with a Q2 earnings beat doing the work that its post-2000 stagnation had undone. The milestone looked symbolic at the time, but the coverage that followed turned it into an inflection point: within eighteen months Microsoft had surpassed Alphabet's market value for the first time in three years.
First-order effects
- Investors immediately re-rated Microsoft on the earnings beat, restoring a valuation last seen at the height of the dot-com era and ending a seventeen-year discount to its own 2000 peak.
Second-order effects
- Alphabet and other mega-cap peers lost relative standing as capital rotated toward Microsoft's cloud-and-software story — a rotation confirmed when Microsoft passed Alphabet by roughly $10B the following year.
Third-order effects
- The 2017 crossing proved durable rather than cyclical: Microsoft went on to briefly touch $1T in 2019 and reach $4T in 2025, second only to Nvidia, making this the first marker in a compounding hyperscaler valuation arc driven by successive earnings beats.
The trend: Mega-cap tech valuations are compounding around cloud and AI earnings power, with each of Microsoft's round-number crossings since 2017 marking a step in hyperscalers' decoupling from the rest of the market.
