Bitcoin Crosses $81,000, Lifting Crypto Stocks Alongside It

Bitcoin Rallies Over $81,000 — And Brings BTC-Related Stocks With It

Bitcoin climbed on Thursday, though shares of companies tied to the crypto sector rose at an even faster pace as a rally that began weeks ago regained momentum.

The largest digital currency by market cap reached as high as $81,282 during Thursday's New York session, rising nearly 3% in a 24-hour window.

Over the last month, bitcoin's price has advanced more than 23%, driven by favorable regulatory developments and announcements from the U.S. Treasury Department concerning debt buybacks.

Yet shares of major crypto firms saw even bigger gains. Strategy (NASDAQ: MSTR), a bitcoin treasury company, traded more than 13% higher on Thursday. It resumed bitcoin purchases on Monday after a 10-week pause to restructure its cash balance sheet.

The largest U.S. crypto exchange, Coinbase, also experienced a sharp increase in its stock. Nasdaq-listed COIN was up 11% over the same period.

Bitcoin mining companies also received a boost. Leading public firms in the sector — including Nasdaq-listed HIVE Digital, MARA, and CleanSpark — all posted gains on Thursday.

HIVE Digital led with a 13% rise, while MARA Holdings climbed more than 10% during the day.

Clean energy bitcoin miner CleanSpark surged 9%; IREN, which is gradually winding down mining operations to pivot to AI-compute, rose 4%.

Bitcoin had a strong August — its third best such month on record — after the U.S. Treasury Department announced plans to more than double its government debt repurchases.

That move, intended to curb surging yields not seen in nearly two decades, weakened the dollar but boosted non-yielding assets such as bitcoin and gold.

Shortly after, President Donald Trump pushed lawmakers to finalize the long-awaited crypto Clarity Act, digital asset legislation the industry has sought for years.

Investors consequently poured back into bitcoin exchange-traded funds, funneling over $2.8 billion into the vehicles — the highest level since October, when the coin reached a new all-time high.

Bitcoin spent much of the year trading below $80,000, with June and July mostly under $65,000. The coin hit a record $126,080 in October and now sits nearly 40% below that level.
