Bitcoin Jumps into High $79,000s as Spot-ETF Inflows and Short Squeeze Fuel Rally

Bitcoin surged into the high $79,000s this week, nearing $80,000 after a rally of roughly 20% over Aug. 19-21, as heavy inflows into U.S. spot-Bitcoin exchange-traded funds and a large short squeeze combined to fuel the move.

The advance stood out because it appeared to be driven by more than thin speculative trading. Traders pointed to two forces working at once: fresh institutional demand flowing through spot Bitcoin ETFs and forced buying in derivatives markets as bearish bets were unwound. Market coverage and historical exchange data cited in the research showed bitcoin trading in roughly the $79,393 to $79,500 range on Friday, but did not independently confirm a print at or above $80,000.

The Block reported that U.S. spot Bitcoin ETFs took in about $606.3 million in net inflows on Thursday alone and about $1.6 billion for the week ending Aug. 21. Those totals can vary somewhat depending on the tracker and time zone used, but the overall picture was one of strong demand. For context, The Block also reported that combined assets in U.S. spot Bitcoin ETFs had climbed to more than $85 billion by around Aug. 21.

At the same time, a short squeeze accelerated bitcoin’s rise. In a short squeeze, a rising price forces traders who had bet on a decline to buy back the asset to close positions or meet liquidations, which can push prices even higher. Coverage citing CoinGlass said about $2.7 billion of short positions were liquidated over a 24-hour period around Aug. 19-21. As with ETF-flow data, liquidation totals can differ by vendor and by the time window measured.

Traders and analysts also cited a macro catalyst from Washington. On Aug. 19, the U.S. Treasury said it would “increase, by at least double, the size of liquidity support buyback operations for longer-dated nominal coupon securities,” raising the previous $2 billion maximum per operation to at least $4 billion. The change applies to operations from Sept. 9 through Nov. 4, 2026. Bernstein analysts, quoted by The Block on Friday, said: “We are not macro experts, but we do know bitcoin historically has had a positive reaction to liquidity expansion.”

A separate sentiment boost came from crypto policy headlines. The Block reported that President Donald Trump met with crypto executives around Aug. 19-20 and urged passage of the CLARITY Act along with other industry-friendly regulatory steps. That was treated by traders as supportive background for a market already moving sharply higher, though it was secondary to the ETF flows and derivatives activity.

The ETF piece matters because the funds, which began trading in the United States after Securities and Exchange Commission approvals in early 2024, are generally backed by purchases of spot Bitcoin when new shares are created. Sustained net inflows are therefore widely viewed as evidence of real buying demand rather than purely speculative positioning.

The rally also spread beyond bitcoin itself. Crypto-linked stocks including Coinbase, the U.S. crypto exchange; Strategy, the company formerly known as MicroStrategy and a major corporate holder of bitcoin; and Circle, the stablecoin company, moved higher alongside the token, according to market coverage. That broader rise suggested the week’s move was being felt across the crypto market, not just in bitcoin’s price alone.
