Marathon Digital, a leading Bitcoin miner, is set to join the S&P SmallCap 600, propelling its shares up by 18%. Announced to replace Aaon in the index on May 8, the move reflects Marathon's growing influence in the cryptocurrency mining sector.

Marathon Digital Stocks Surge 18% as It Joins S&P SmallCap 600, Showcasing Robust Growth Ahead of Earnings Report

In a recent report by Cointelegraph, Marathon Digital, the world's most significant Bitcoin (BTC) miner by market capitalization, saw its stock price climb 18% after being confirmed to join the S&P SmallCap 600 index fund.

Marathon will replace Aaon, a heating and ventilation manufacturing corporation, in the S&P Dow Jones Indices index on May 8, according to a statement issued after trade on Friday, May 3.

The S&P SmallCap 600 index measures 600 US companies with market capitalizations ranging from $1 billion to $6.7 billion that reported earnings in the most recent quarter and the previous four quarters.

According to Google Finance, Marathon Digital (MARA) shares rose 18% on Monday, May 6, to $20.67.

Its stock price has risen 25.2% since the April 20 Bitcoin halving, which reduced miner block rewards from 6.25 BTC to 3.125 BTC, approximately $198,000 at current levels.

However, MARA is down 9.86% year to date, having set a 2024 high of $31.03 on February 28. Marathon is likely to be one of the larger-weighted stocks, given its $5.6 million market capitalization and the fact that the S&P SmallCap 600 employs a float-adjusted market cap weighting approach.

Marathon's inclusion in the index comes as it prepares to report its first-quarter earnings on May 9, which investment research company Zacks estimates will show a 280% year-on-year (YOY) revenue increase to $193.9 million and $0.02 earnings per share — a 166.7% YOY increase.

Rival Bitcoin Miners CleanSpark and TeraWulf See Stock Gains Amid Market Shifts Post-Halving

On May 6, shares of Marathon's competing Bitcoin mining firms reacted well, with CleanSpark (CLSK) and TeraWulf (WULF) up roughly 8% and 10.7%, respectively.

The increase in Bitcoin mining stocks coincides with a fall in miner revenue due to the halving.

For the first few hundred blocks after halving, transaction costs remained continuously over 3.125 BTC, compensating for the newly halved block subsidy.

However, transaction costs have since dropped and are presently hanging between 0.2 and 1 BTC at block 842,350, according to mempool—space data.
