About Riot Blockchain, Inc.

Riot Platforms, Inc. (formerly Riot Blockchain, Inc.) is a U.S.-based company listed on the NASDAQ in the United States, operating at the intersection of Bitcoin mining and large-scale digital infrastructure. Over time, the company has shifted from a broader blockchain theme toward a more focused Bitcoin-mining model, and more recently toward a diversified data-center and digital-infrastructure platform. The company is headquartered in Castle Rock, Colorado. ([riotplatforms.com](https://www.riotplatforms.com/?utm_source=openai)) Originally established under a different corporate identity and subsequently repositioned through strategic changes, Riot has become one of the most visible publicly traded Bitcoin miners in North America. Its core business centers on industrial-scale data-center operations, the deployment and management of Bitcoin mining hardware, and the buildout of supporting power and infrastructure assets. In recent disclosures, Riot explicitly describes its strategy as evolving from a bitcoin-mining-focused business into a broader digital infrastructure company. ([riotplatforms.com](https://www.riotplatforms.com/?utm_source=openai)) From a competitive standpoint, Riot benefits from meaningful scale in the North American mining landscape and emphasizes ownership and operation of one of North America’s largest Bitcoin mining facilities by developed capacity. Its operational footprint is concentrated in the United States, including mining facilities in Kentucky and Texas referenced in its fiscal 2025 annual report. This U.S.-only concentration gives the company strong exposure to domestic power markets, data-center demand, and Bitcoin economics, while also leaving it highly sensitive to electricity prices, network difficulty, regulatory shifts, and crypto-cycle volatility.

The company is effectively a specialized digital-infrastructure operator, where performance depends on mining efficiency, power economics, and the market value of Bitcoin rather than on conventional industrial margins. ([riotplatforms.com](https://www.riotplatforms.com/?utm_source=openai)) Recent highlights include the company’s fiscal 2025 annual report, filed in March 2026, which showed deployed hash rate rising to 38.5 EH/s at December 31, 2025, from 31.5 EH/s a year earlier, signaling continued operational scaling. Riot has also maintained its strategic push into data centers and AI/HPC infrastructure. On the market and governance side, the stock is closely followed on NASDAQ, including through SEC Form 4 filings that track insider transactions.
