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 evolution from a bitcoin mining-centric company to one focused on AI 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 anticipated to generate approximately $636 million over a 10-year period, as per the earnings transcript.

Additionally, 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. As Matthew Sigel, head of digital assets research at VanEck, noted, '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 by opening their data centers to non-mining activities.

However, with activist investor Starboard urging the management to accelerate its transition to an AI infrastructure provider, Riot's strategic expansion of its data center business to host AI computers appears to be yielding positive results. The company 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 heightened mining competition, the company's shares have surged approximately 147% over the last 12 months, while bitcoin has fallen nearly 17%. Furthermore, Riot, which had previously retained all its mined bitcoin, is now accelerating its bitcoin sales.

As per Bitcoin Treasuries data, the company sold 3,688 BTC during Q1, ending March with 15,679 BTC and $282.5 million in cash.
