Bitcoin ETF Flows Return to Net Inflows as BTC Tops $81,000

US spot Bitcoin exchange-traded funds (ETFs) finished the last five trading sessions roughly flat, as sizable inflows at the start and end of the stretch offset a sharp two-day bout of redemptions. Data from Farside Investors show spot Bitcoin ETFs logged $159.9 million in net inflows on Sept. 14, before sentiment turned. Investors withdrew $450.4 million on Sept. 15 and another $295.9 million on Sept. 16, taking the two-day outflow to about $746.3 million. Buying interest then re-emerged. The ETFs brought in $159.5 million on Sept. 17, followed by $433 million on Sept. 18, the strongest daily tally across the five-session window. In total, net inflows for the period came to about $6.1 million. Fidelity's FBTC led the Sept. 18 gains with $310.7 million in inflows, while BlackRock's IBIT added $108.4 million. IBIT also drew $183.7 million on Sept. 17 after posting sizeable withdrawals over the prior two sessions. The swings in ETF demand tracked a notable move in Bitcoin's price. BTC began the week in the upper-$70,000s and briefly cleared $79,000 before selling pressure intensified. On Sept. 15 and Sept. 16, Bitcoin dropped below $76,000, coinciding with the two heavy ETF outflow days. Momentum improved later in the week. Bitcoin reclaimed $77,000 on Sept. 17 and pushed through $80,000 around Sept. 18 as institutional inflows returned. Over the weekend, BTC held up relatively well, trading around $81,000–$81,500, dipping toward the low $80,000s and then rebounding. By early Sunday, it was changing hands near $81,000. Overall, the week delivered a mixed but strengthening signal: ETF investors briefly reduced exposure aggressively, yet most of those outflows were effectively reversed by week's end, alongside BTC's recovery from below $76,000 to above $81,000.
