Mega-Caps Moving at Startup Speed (October 2026)

The giants still moving.

Above a few hundred billion in market cap, growth is supposed to be finished. Sixteen mega-caps moving at startup speed argue otherwise. Mastercard leads with an MGI of 63, Palantir follows at 61, and AMD and ASML match it, all while carrying caps between $332B and $764B.

The median of 50.5 is the honest number, the lowest of our size tiers, because MGI asks how much room a company has left to multiply, and at $1.8T even Taiwan Semiconductor's 21% yearly growth earns only a 52. This list is less a promise of speed than a census of giants that refuse to slow down. Click any name for the full citation-backed analysis.
