Bitcoin's $14,775 Weekly Surge Is the Biggest in Its History, Powered by ETF Flows

Bitcoin (BTC) gained $14,775 in a single week, the largest one-week dollar increase in its history. Galaxy Research says the rally also drove the strongest US spot Bitcoin ETF inflow week since October 2025.

The weekly close jumped from $62,818 to $77,593, a 23.5% move ranked 41st by percentage increase since 2010. By percentage increase, it was Bitcoin’s best week since March 2023. What Drove Bitcoin’s Record Week Galaxy Research linked the rally to two catalysts.

The US Treasury said it would double its long-bond buyback operations, used to ease pressure on Treasury yields. Last week's BTCUSD weekly candle was the single largest weekly gain by dollar amount in Bitcoin history.
