Shares of Riot Platforms (RIOT) experienced a significant 8% increase on Friday, driven by the announcement that Advanced Micro Devices (AMD) would be expanding its capacity at Riot's Rockdale, Texas campus. This development highlights Riot's ongoing pivot 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 potential for further expansion to 150MW.

The agreement is anticipated to generate approximately $636 million over a 10-year term, as per the earnings transcript. Furthermore, Riot has secured more favorable terms on 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 bitcoin.

This move signals growing lender confidence in Riot's expanding data center business. The combined impact of the AMD deal and improved credit terms has led investors to pay a premium for the stock. 'The market is factoring in a lower cost of capital as the expanded AMD deal boosts lender confidence,' noted Matthew Sigel, head of digital assets research at VanEck.

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. Recently, activist investor Starboard urged the management to accelerate its transition from bitcoin mining to an AI infrastructure provider.

The decision to expand its data center business to host AI computers appears to be yielding positive results for the Castle Rock, Colorado-based company. The firm reported total revenue of $167.2 million for the quarter ended March 31, up from $161.4 million in the previous year, supported by $33.2 million in initial data center revenue. However, revenue from bitcoin mining declined to $111.9 million from $142.9 million, primarily due to lower bitcoin prices and increased mining competition. Over the last 12 months, the mining company's shares have surged by approximately 147%, while bitcoin has fallen by nearly 17%.

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