On September 21, Riot Platforms rose 5.26% in regular trading, trading at $25.04 per share, with turnover of approximately $183 million. The rally extends a multi-session advance in crypto-related equities fueled by Bitcoin reclaiming the $80,000 level and a series of favorable U.S. regulatory developments.

On the regulatory front, the SEC recently issued guidance permitting qualified platforms to trade tokenized stocks, while the CFTC advanced a new crypto regulatory framework. Bitcoin ETF inflows also resumed, with funds managed by BlackRock and others recording approximately $160 million in net inflows in a single session, ending a prior streak of outflows. These developments collectively boosted risk appetite across crypto concept names.

Riot Platforms also benefits from company-specific catalysts. The firm signed a 20-year, 191-megawatt data center lease with Anthropic valued at an estimated $9.1 billion in total revenue, marking a pivotal step in its strategic pivot from pure bitcoin mining toward AI-driven high-performance computing infrastructure. Morgan Stanley initiated coverage with an Overweight rating.

Within the Application Software sector, Strategy rose 8.6%, Circle Internet Corp. gained 3.18%, Palantir Technologies added 2.43%, and IREN Ltd advanced 2.02%.
