Shares of Cipher Mining
(NASDAQ: CIFR) experienced a significant downturn, closing at $11.64, a decrease of 17.7%. Trading activity saw a substantial increase, with approximately 153 million shares changing hands, exceeding its typical three-month trading volume by about 4.1 times.
The broader market also showed weakness, as major indices closed in negative territory. The
S&P 500
(SNPINDEX: ^GSPC) ended the day at 6,604.72, down 0.5%. Similarly, the
Nasdaq Composite
(NASDAQINDEX: ^IXIC) also fell by 0.5%, closing at 22,384.70, weighed down by losses in technology sector stocks.
Other companies in the Bitcoin mining
industry also faced headwinds.
Riot Platforms
(NASDAQ: RIOT) saw its stock price decline by 7% to $16.74, while
Hut 8 Corp
(NASDAQ: HUT) dropped 7.9% to $34.88. These declines were largely attributed to the overall weakness in
Bitcoin
(CRYPTO: BTC), which decreased by 3.4% to $109,534.50, impacting related stocks across the cryptocurrency market.
Cipher Mining’s decline occurred despite a recent announcement regarding a significant 10-year agreement with Fluidstack for artificial intelligence (AI) hosting services. The deal is valued at approximately $3 billion, with potential extensions that could increase the total value to nearly $7 billion.
Alphabet
(NASDAQ: GOOGL)
(NASDAQ: GOOG) is set to guarantee $1.4 billion of lease obligations under this agreement and will receive
warrants
representing approximately 5.4% equity in Cipher. Although the agreement underscores Cipher’s movement into the high-performance computing sector, the day’s trading activity highlights the stock’s continued susceptibility to fluctuations in the price of Bitcoin.
