Bit Digital (BTBT) surges 10.40% after S&P Software & Services Select Industry Index inclusion

Bit Digital Inc. (BTBT) surged 10.396% in pre-market trading on Dec. 22, 2025, following its inclusion in the S&P Software & Services Select Industry Index. The addition, effective Dec. 21, positions the miner as a focal point for investors tracking the index, which highlights key players in the software and services sector.

The move underscores growing institutional interest in Bitcoin mining equities as part of broader portfolio diversification strategies. Analysts note that index inclusion often enhances liquidity and visibility for smaller-cap names, though operational performance remains critical for sustained momentum.

With the S&P's benchmark status, the listing could attract passive fund flows tracking the index. However, market participants remain cautious about macroeconomic headwinds and energy cost volatility, which continue to weigh on the sector's long-term outlook.

Investors are also evaluating the potential for increased trading volume and volatility around the index inclusion, which could influence short-term price action. While the fundamental business model of Bitcoin mining remains sensitive to energy prices and regulatory developments, the recent listing offers a new narrative for the stock.

As the market digests the broader implications of the index addition, long-term holders are advised to monitor both technical indicators and the company's operational efficiency to gauge the strength of this new momentum.
