Shares of Riot Platforms (RIOT) experienced a significant 8% increase on Friday, driven by the announcement of Advanced Micro Devices (AMD) expanding its capacity at Riot's Rockdale, Texas campus. This development underscores Riot's ongoing transition from bitcoin mining to artificial intelligence and high-performance computing. According to the company's Q1 financial results, AMD has exercised an option to double its contracted capacity to 50 megawatts (MW), with the potential for further expansion to 150MW. The agreement is expected to generate approximately $636 million over a 10-year period.

Additionally, Riot has secured more favorable terms for its $200 million bitcoin-backed credit facility with Coinbase, reducing the interest rate to a fixed 6.15% from 8.3% and releasing 1,544 pledged collateral bitcoins. This move signals growing lender confidence in Riot's expanding data center business. The combination of the AMD deal and improved credit terms has led investors to pay a premium for the stock, with market pricing reflecting lower costs of capital. Matthew Sigel, head of digital assets research at VanEck, noted that 'market pricing in lower cost of capital as the expanded AMD deal drives lender confidence.' Riot was one of the last remaining 'pure play' mining companies that had not ventured into hosting AI computing, while its peers had begun to diversify their data centers.

However, with the urging of activist investor Starboard, Riot has accelerated its transition from bitcoin mining to an AI infrastructure provider. The expansion of its data center business to host AI computers appears to be yielding positive results for the company. Riot reported total revenue of $167.2 million for the quarter ended March 31, representing a increase from $161.4 million in the same period last year, supported by $33.2 million in initial data center revenue. Although bitcoin mining revenue declined to $111.9 million from $142.9 million due to lower bitcoin prices and increased competition, the company's shares have surged approximately 147% over the last 12 months, while bitcoin has fallen nearly 17%.

Furthermore, Riot, which previously retained all its mined bitcoin, is now accelerating its bitcoin sales. According to Bitcoin Treasuries data, the company sold 3,688 BTC during Q1 and ended March with 15,679 BTC and $282.5 million in cash.
