BTC Tests $80K as Spot ETFs Pour in $2.8B Over Eight Days — BlackRock's IBIT Leads

Headline: Bitcoin ETFs Keep the Money Flowing — $2.8B in Eight-Day Streak as BTC Tests $80K Lede: Bitcoin traded around $79,520 on Thursday after an intraday high of $80,475, as U.S. spot Bitcoin ETFs extended an eight-session inflow streak that brought in $2.8 billion. The run highlights continued institutional demand for spot exposure and a bifurcation within the ETF complex that’s reshaping flows and price dynamics. Key facts - BTC price: about $79,520 (intraday high $80,475). - Eight consecutive trading sessions of net inflows into U.S. spot Bitcoin ETFs totaling $2.8 billion (Farside Investors). - BlackRock’s IBIT accounted for $2.02 billion — roughly 72% of the eight-day total. - Grayscale’s GBTC lost money over the stretch, including a $50.4 million outflow on Wednesday. - Since launch, cumulative net inflows into the spot-BTC ETF category stand at $54.7 billion: IBIT +$63.1 billion, GBTC -$27.6 billion. Context and market reaction Bloomberg ETF analyst Eric Balchunas highlighted that gold and Bitcoin funds together pulled in about $7 billion over the past week — a record for a five-day period — and suggested that a “debasement” trade (inflation/monetary concerns) is drawing capital away from AI trades. He also noted IBIT has climbed back into positive year-to-date flows after a long stretch of outflows. Trading and volume signals - Algoz Technologies’ Stephen Wundke said weekly trading volumes topped $90 billion — roughly double the average — with Bitcoin accounting for just under $40 billion. Weekly ETF inflows of nearly $2 billion matched the previous 30 days combined; if August holds, it could be the strongest month since October 2025 by this metric. - Inflow intensity has eased after peaking: the largest single-day inflow was $606.3 million on Aug. 20; none of the more recent sessions exceeded $340 million, and Wednesday’s $232.2 million was the smallest of the eight-day run. Caution from researchers Tim Sun, senior researcher at HashKey, urged caution about over-interpreting single-day flows. His analysis shows a positive but modest long-term correlation between flows and price (coefficient below 0.5), implying roughly a 0.4% BTC price move per $100 million of net inflow. Sun calls ETF flows a trend-confirmation indicator rather than a reliable day-to-day price predictor. Where this matters: sustained demand vs. momentum - Sun said streaks longer than five days are meaningful because they point to “sustained spot demand.” This current inflow run follows a steep correction from the $60k–$70k range, suggesting ETF capital is increasingly comfortable with the new price band and that market consensus on a temporary bottom may be firming. - He sees near-term resistance around $85,000. A key test, according to Sun, will be whether prices can pause or dip slightly while inflows persist — that would indicate fresh capital absorbing selling rather than momentum-driven froth. The slip back below $80,000 on Thursday offers an early read; full flow data for the day were not yet available at the time of reporting. - Wundke added that a sustained hold above $72,000 would likely reassure investors that pullbacks are buying opportunities. Bottom line: Institutional ETF demand is still a major driver for BTC, with BlackRock’s IBIT taking the lion’s share of new capital. The recent streak matters because it signals deeper acceptance of current prices, but analysts caution that flow strength has softened from earlier peaks and single-day inflows aren’t a foolproof short-term price signal. Watch whether inflows persist if prices stall — that dynamic will help determine whether this is consolidation with new buyers or the tail end of momentum.
