Stacks (STX) Plunges Amid Regulatory Shock and Market Selloff

Stacks (STX) dropped 8-9 percentage points over the last day due to regulatory shock and market selloff. The failure of the US Digital Asset Market CLARITY Act on September 15, 2026, triggered a sharp decline across crypto markets. Bitcoin fell below $75,000, while total crypto market cap slipped around 0.9 percent in a short span.

The defeat of the bill increased regulatory uncertainty and coincided with heavy outflows from US spot Bitcoin ETFs. Major coins like BTC, ETH, XRP, and SOL also experienced broad weakness. Stacks (STX) is considered a mid-cap coin with daily spot volume in the tens of millions of dollars.

The token's price moved from around $0.25 to $0.23 in several steps, while its market cap slid from approximately $461 million to $424 million. This represents a relatively modest absolute dollar move but a large percentage swing due to the low base price. STX's behavior aligns with that of high beta altcoins during regulatory shocks.
