Bitcoin miner Riot Platforms stock jumps nearly 9% as Starboard urges AI data center expansion

Shares of Riot Platforms (RIOT) rose nearly 9% Wednesday after activist investor Starboard Value LP released a letter pressing the company to accelerate its transition from bitcoin mining to AI infrastructure provider. The aim is for Riot to pursue high-margin artificial intelligence and high-performance computing (AI/HPC) hosting deals.

Riot’s 1.7 gigawatts of fully available power capacity make the company “well positioned to execute high-quality AI/HPC deals,” said Starboard, highlighting two of Riot’s Texas-based sites, Corsicana and Rockdale, as “premier” locations for data center development.

Starboard said that if Riot can monetize its power in line with recent transactions in the space, “it could generate more than $1.6 billion” in annual EBITDA. The group praised Riot’s recent deal with AMD, which is projected to yield $311 million over 10 years.

With a market cap of $4.25 billion, Texas-based Riot is the fifth-largest bitcoin mining company in the U.S. Its shares have risen by 19% in the past year, but remain lower by about 80% from highs hit during the 2021 bitcoin bull market. They've also underperformed miners like IREN, Cipher Mining, and Hut 8, which were quicker to recognize and transition to AI strategies.

Starboard was Riot’s fourth-largest shareholder as of the end of last year, and this isn't its first push on the company. In December 2024, Starboard requested that Riot convert some of its bitcoin mining sites into data centers capable of hosting HPC machines to support big tech companies.

While Riot Platforms has built its business around bitcoin mining, the pivot toward AI infrastructure could diversify revenue as power-hungry models like OpenAI’s GPT-4o and others drive data center demand. Riot’s power access, a rare commodity in the current energy-constrained data center market, could be used to lease capacity to major AI firms.

Starboard urged CEO Jason Les and Executive Chairman Benjamin Yi to act “with urgency” and position Riot as a long-term infrastructure provider for AI workloads.
