Stock market concentration is hitting unprecedented levels. The seven largest companies now account for 36% of the S&P 500's total market capitalization—a stunning milestone that tells you everything about current market dynamics.

Consider the trajectory: this concentration has doubled over the past seven years alone. Even more striking, it now surpasses the 2000 Dot-Com Bubble peak by 13 percentage points, suggesting we're in genuinely uncharted territory.

These same seven stocks represent approximately 26% of broader market valuations. The math here matters because when this few companies dominate this heavily, market movements become increasingly volatile and concentrated. For crypto investors tracking macro trends and systemic risks, this concentration pattern mirrors similar dynamics we've seen emerging in digital asset markets. Asset concentration remains one of the most critical indicators for understanding overall market health and downside risk.
