Bitcoin logs record $14,775 weekly gain on ETF inflows

In a single week, bitcoin (BTC) surged by $14,775 — a record dollar increase for any seven-day period. According to Galaxy Research, the rally also produced the most substantial week of US spot bitcoin ETF inflows since October 2025.

The weekly closing price rose from $62,818 to $77,593, representing a 23.5% gain. That ranks as the 41st-largest weekly percentage increase since 2010 and the strongest for bitcoin since March 2023.

What Drove Bitcoin’s Record Week

Galaxy Research attributed the surge to two factors. The US Treasury announced it would double its long-bond buyback operations, a measure designed to relieve pressure on Treasury yields.

President Trump also called on Congress to pass the CLARITY Act. The legislation would establish federal guidelines for determining whether digital assets are securities or commodities.

The price action also set off a short squeeze. Traders holding short positions on bitcoin were compelled to close them, fueling the cryptocurrency's fastest bull flip in a year.

Approximately $2.7 billion in short positions were liquidated across the crypto market during that week, per CNBC.

Market sentiment also shifted dramatically. The Crypto Fear and Greed Index hit 74 on August 25, marking its highest reading since October 2025.

ETF Inflows Confirm the Rebound

Concurrently, demand for spot bitcoin ETFs revived. Weekly inflows posted their strongest level since October 2025, according to Galaxy Research.

August is poised to record the largest monthly net inflow since bitcoin's previous all-time high. Such a figure would flip months of ETF outflows that had made the funds net sellers in 2026.

Despite the rally, ETF holders are still roughly 6% below break-even. Their average cost basis is $84,029, compared with a spot price of $78,955, according to Galaxy Research.

On Thursday, bitcoin's spot price traded above $80,000.

The sustainability of the rebound may hinge on whether ETF inflows persist into September. Traders will also be monitoring whether last week's short squeeze proves durable or transitory.
