Crypto-related stocks including Galaxy Digital (GLXY), Circle Internet (CRCL) and Bitfarms (BITF) posted double-digit gains on Thursday as bitcoin (BTC) rose the highest since mid-August.Galaxy, a digital asset investment and data center conglomerate led by Mike Novogratz, added 12%. The company was a lead investor in Forward Industries' $1.65 billion fundraising closed today to build a Solana (SOL) treasury vehicle.It might also be benefiting from rising appetite for data center plays, as big tech firms make billion-dollar artificial intelligence (AI) hosting contracts such as Microsoft's deal with Nebius on Tuesday.The same logic applies to bitcoin miner Bitfarms (BITF), which has set out to expand in high-performance computing and appointed Wayne Duso, a former executive of cloud service giant Amazon Web Services, to the board last month. The stock advanced another 18% today, extending gains to more than 60% this week.For USDC stablecoin issuer Circle, Thursday's 16% rally could be a technical rebound absent any clear news catalyst, breaking the downtrend that started in June and saw the stock decline roughly 60% from its post-IPO peak.Crypto exchange Coinbase (COIN), digital trading platform Robinhood (HOOD) and bitcoin miners MARA Digital (MARA) and Riot Platforms (RIOT) also advanced.The companies outpaced the broader equity markets, with the S&P 500 index recently up 0.82% and the Nasdaq 100 index 0.69% higher.Meanwhile, bitcoin treasury vehicles Metaplanet (3355) and Nakamoto (NAKA) declined 10% and 14%, respectively. Strategy (MSTR), the largest corporate owner of BTC, was little changed.The declines occurred even as bitcoin advanced toward $115,000, rebounding from an initial dip on rising CPI inflation and higher jobless claims reports in the early U.S. morning hours.Read more: Strategy's S&P 500 Snub Is a Cautionary Signal for Corporate Bitcoin Treasuries: JPMorgan
