Bitcoin Spot ETFs See $131M Outflow Led by Fidelity and Ark

Bitcoin News

US spot Bitcoin (BTC) exchange-traded funds posted a net outflow of $131.13 million on Aug 13, fund-flow data shows, a sharp pullback in demand for Bitcoin products. Spot ETF flows — the net creation and redemption of fund shares — are watched as a proxy for institutional demand, and the window for this reading is the single US trading session of Aug 13. Redemptions were concentrated among two issuers: Ark Invest and 21Shares' ARKB fund lost $58.82 million — the largest single outflow — while Fidelity's FBTC shed $55.12 million, with the pair together accounting for $113.94 million of the day's total. Across that same session, the two largest crypto assets' fund vehicles moved in opposite directions. Even as Bitcoin funds bled capital, spot Ethereum exchange-traded funds attracted a modest $6.72 million, leaving the combined two-asset complex with roughly $124.41 million in net outflows. Total trading volume in the Bitcoin ETF complex reached $1.24 billion, a sign of active rotation rather than a clean exit from the market; the Ethereum funds traded $339.77 million on the day. Since inception, US spot Bitcoin ETFs have accumulated $51.85 billion in net inflows, with total net assets of $77.27 billion — about 6.07% of Bitcoin's market capitalization. The Ethereum products, by contrast, hold $10.57 billion in net assets against $11.45 billion in cumulative inflows, roughly 4.64% of Ethereum's market cap. Our reading of the split is that it reflects asset-specific positioning rather than a blanket risk-off move across the whole crypto ETF complex: capital is rotating within the major-asset and altcoin universe instead of fleeing it outright. That divergence — Bitcoin outflows against Ethereum inflows — is the defining feature of the session, and the concentration of withdrawals in Fidelity and Ark products, set against small inflows elsewhere, points to profit-taking or rebalancing in the largest non-BlackRock funds rather than a broad redemption wave.

The fund-level breakdown shows withdrawals spread across most major Bitcoin products, with only a few pockets of inflow. Grayscale's GBTC saw $36.29 million leave, Bitwise's BITB recorded a $9.28 million outflow, and Invesco's BTCO lost $7.88 million. Even BlackRock's IBIT — the largest spot Bitcoin ETF by assets — posted a modest $5.74 million net outflow, a small figure for a fund of its size but notable because it signals that even the market leader was not immune to the day's selling. Against that tide, Grayscale's mini Bitcoin Trust (BTC) drew $38.93 million — the largest single inflow of the session — and Morgan Stanley's MSBT added $7.08 million, though those gains were not enough to offset the Fidelity and Ark redemptions. By scale, BlackRock's IBIT remains the dominant vehicle, holding $47.34 billion in net assets against $61.15 billion in cumulative net inflows since launch. Fidelity's FBTC ranks second with $10.79 billion in net assets and $9.88 billion in cumulative inflows. The day's pressure nonetheless fell on the ARKB and FBTC pair rather than on the market leader, which limits the read-through for the broader Bitcoin ETF structure and keeps the episode issuer-specific for now. On the Ethereum side, the modest inflow was led by Grayscale's mini Ethereum trust, which took in $6.47 million, with Morgan Stanley's MSSE adding $811,330. BlackRock's ETHA shed $569,200, while Fidelity's FETH and Grayscale's ETHE saw no notable flow. BlackRock's ETHA kept its position as the largest Ethereum fund with $5.66 billion in net assets and $11.63 billion in cumulative inflows, and Grayscale's ETH product holds $1.6 billion in net assets against $1.82 billion in cumulative inflows. The outstanding question for coming sessions is whether Bitcoin's outflow streak extends and whether Ethereum's inflows can broaden into the larger BlackRock and Fidelity products — the signal that would turn a one-day rotation into a durable trend.

COINOTAG's proprietary 42-indicator composite scoring engine reads Bitcoin in a downtrend, spot $62,931, RSI 43. It rates the $63,787 resistance at 82/100 — Pivot Point, SMA 50 and Fibo 0.236 — and the $62,884 support at 68/100 off the Ichimoku Cloud bottom. Derivatives lean long: long/short ratio 2.02, open interest $13.66 billion, funding near flat at 0.0045%, Fear & Greed at 29 (Fear), far from all-time high euphoria. Below $63,787 the bias stays bearish — a step short of a bear market; a close above invalidates the read, while a break under the 61/100 $62,222 support opens the $61,056 floor. Our flow and price series currently agree: $131.13 million in outflows alongside a 1.54% daily decline.
