Bitcoin (BTC) ETFs Draw $242.24 Million in Ninth Straight Inflow Day

Ninth Straight Inflow Session

U.S. spot Bitcoin (BTC) exchange-traded funds drew $242.24 million in net inflows on Aug. 27, extending the category's run to nine consecutive trading sessions, according to daily Bitcoin ETF flow data. The streak dates to Aug. 17 and has not broken since, and the daily total widened roughly 1.0x versus the prior session. Six of the twelve funds in the category absorbed money on the day. Cumulative net inflows across all U.S. spot crypto ETFs tracking bitcoin now stand at $54.83 billion since launch. Steady creations pull coins off spot exchange order books, a supply dynamic that has historically supported price through past accumulation phases. Bitcoin itself traded near $80,000 on Thursday, up 2.12% over 24 hours, with no visible pause in institutional demand at the nine-day mark.

BlackRock's IBIT Absorbs the Bulk

BlackRock's iShares Bitcoin Trust (IBIT) took in $277.61 million on Aug. 27 — more than the category's entire net figure, since redemptions elsewhere offset part of its intake. IBIT's cumulative net inflows have reached $63.4 billion, and its net assets stand at $62.29 billion, making the fund the dominant whale among spot bitcoin issuers. The rest of the inflow list was thinner: Ark Invest and 21Shares' ARKB added $29.75 million, Bitwise's BITB $21.74 million, Grayscale's BTC trust $11.66 million, Morgan Stanley's MSBT $6.66 million and VanEck's HODL fund $5.66 million. The concentration matters for market structure: a nine-day streak resting overwhelmingly on one issuer is more sensitive to a single desk's allocation decisions than a flow spread evenly across twelve products.

Fidelity and Grayscale Shed $111 Million

Fidelity's FBTC redeemed $83.63 million on the day and Grayscale's GBTC shed $27.21 million — the only two funds to log outflows. Despite the redemptions, total net assets across U.S. spot bitcoin ETFs stand at $100.93 billion, equal to roughly 6.28% of Bitcoin's total market capitalization. Category trading volume reached $3.45 billion, led by IBIT at $2.77 billion, followed by FBTC at $332.19 million and GBTC at $110.75 million. The rotation — money leaving the two legacy-heavyweight funds and landing in BlackRock's product — echoes a pattern that has held since the ETFs launched in January 2024. It also fits the broader risk backdrop: Nuveen's Saira Malik has tied equity appetite, including a software rebound, to bitcoin's resilience this month.

Ethereum Funds Match the Pace

Spot Ethereum (ETH) ETFs added $234.51 million the same day, their own ninth straight session of net inflows, bringing the combined two-asset daily haul to roughly $477 million. BlackRock's ETHA absorbed $130.22 million of that, with cumulative inflows of $12.65 billion and net assets of $8.63 billion; Fidelity's FETH added $56.23 million, BlackRock's ETHB $20.67 million and Grayscale's ETH fund $14.31 million. Last week marked the two categories' biggest combined week since October, drawing $2.3 billion — evidence institutions are building positions in both assets rather than rotating between them. Smaller funds joined as well: spot Solana (SOL) ETFs drew $60.91 million and spot Hyperliquid (HYPE) ETFs $24.42 million on Aug. 27. Combined net assets across the bitcoin and ether ETF categories now total about $116.5 billion. Readers tracking the market in real time can follow live spot and futures prices on MEXC.

$81,200 Resistance in Focus

A separate macro catalyst has since emerged: bitcoin pushed intraday to $80,808 on Aug. 27, aided by Nvidia's surprise Q2 revenue of $96.2 billion — roughly $4 billion above expectations — which lifted risk appetite across assets and sent the chipmaker's stock up more than 9%, adding over $400 billion to its market cap while the Nasdaq rose 1%. Attention now turns to the Jackson Hole economic symposium, where Fed Chair Kevin Warsh delivers a keynote on Aug. 28; Nationwide chief economist Kathy Bostjancic called the address highly significant given elevated long-term yields and inflation uncertainty. Meanwhile, the $6.4 billion Deribit options expiry — about 81,700 contracts with max pain near $68,000-$70,000 — has cleared, and analysts flag $82,000 as the level whose break would open a cleaner path above $85,000.

A structural read on the rally has also taken shape: analysis framing the week's surge argues this advance is driven by institutions rather than retail chase-buying. U.S. spot bitcoin ETFs absorbed $2.5 billion in net inflows over the past seven trading days — the largest such stretch since last October — with $1.6 billion arriving between Monday and Thursday alone, per Wall Street Journal figures. Grayscale CEO Peter Mintzberg noted that daily ETP flows repeatedly exceeded $500 million in 2025, roughly 12 times the value of newly mined supply, shifting price formation toward institutional capital. A Coinbase and EY-Parthenon survey of 351 institutional investors found 73% plan to raise digital-asset allocations this year, 66% already hold exposure via ETFs or ETPs, and 81% prefer regulated vehicles for spot exposure. Separately, Galaxy Research flagged bitcoin's 50-week moving average near $82,470 — a weekly close above which has marked cycle bottoms in 11 of 13 prior bear markets.

(as of 16:18 UTC) COINOTAG's proprietary 42-indicator composite S/R scoring engine rates the $79,881.48 resistance at 80/100, driven by the confluence of the Fibonacci 0.000 retracement, the Donchian upper channel, the ATR upper band and the pivot point, while the $78,846.86 support scores 71/100 on a flip of resistance into support, the S1 pivot, the Fibonacci 0.114 level and a MACD cross. Bitcoin changes hands at $77,623.12, down 3.56% over 24 hours, with RSI at 77.48 — stretched — and a bullish MACD inside an uptrend. Funding sits at a mild 0.0040% and the long/short account ratio reads 1.19, so leverage is not yet crowded, while sentiment prints 73/100, or Greed. With spot now below $78,846, a daily close back above $79,881 opens the $87,919 Fibonacci extension, rated 50/100; losing $78,847 shifts focus to the $73,043.16 support at 76/100. Open interest across tracked perps stands at $15.15 billion, counting leveraged positions on Binance, Bybit and HyperLiquid.
