Bitcoin ETFs See Largest Outflow Since January As $630M Leaves Funds

U.S. spot Bitcoin ETFs recorded their largest daily outflow since January 30, adding pressure to Bitcoin as the asset struggles to regain momentum near the $80,000 level.

Farside Investors recorded $630.4 million in net outflows from spot Bitcoin ETFs on May 13. The figure is close to the widely circulated $635 million estimate and marks the heaviest single-day redemption since late January, when funds were hit by a sharper institutional pullback.

The selling was broad across major products. Fidelity’s FBTC lost $284.7 million, Ark 21Shares’ ARKB lost $177.1 million, BlackRock’s IBIT lost $133.2 million, and Bitwise’s BITB lost $35.4 million. Several other products were flat on the day, leaving the four largest redemptions to drive the full market total.

The outflow reverses the stronger ETF demand that had helped stabilize Bitcoin earlier this month. Recent market coverage had noted that spot Bitcoin ETFs were coming off their longest inflow streak in nine months, with about $3.4 billion entering the funds across six consecutive positive weeks through May 8.

ETF Demand Weakens As Bitcoin Stalls Near Resistance

Bitcoin was recently trading around $79,768, down about 1.4% on the day, after moving between roughly $78,762 and $81,276. The price action keeps BTC below the 200-day moving average area that traders have treated as a major resistance zone.

That technical backdrop makes the ETF outflow more important. A single day of redemptions does not define the trend, but heavy selling from funds can reduce one of Bitcoin’s clearest institutional demand channels just as spot buyers are trying to defend the upper-$70,000 range.

The timing also overlaps with other pressure signals. Bitcoin recently failed to reclaim the 200-day SMA near $82,500, while the 50-day SMA around $75,000 remains the next major downside level if buyers lose control. That setup has already kept traders focused on whether BTC can hold its recovery structure or retest lower support.

ETF flows are not always direct price signals. Redemptions can reflect portfolio rebalancing, hedging, arbitrage, tax planning, or short-term risk reduction rather than a simple directional bet against Bitcoin. Still, the size of the May 13 outflow makes it harder to ignore because it comes after several sessions of uneven demand.

Market Focus Turns To Follow-Through

The immediate question is whether the May 13 outflow becomes a one-day reset or the start of a deeper redemption stretch. If ETF flows stabilize quickly, Bitcoin can keep trading inside its current range while buyers focus on reclaiming the $82,000 to $82,500 area. If outflows continue, the market may need stronger spot demand to prevent a retest of $75,000.

Farside’s data now leaves traders with a clean institutional-flow checkpoint. May 13 delivered the largest Bitcoin ETF outflow since January 30, led by redemptions from Fidelity, Ark 21Shares, BlackRock, and Bitwise. Bitcoin’s next move depends on whether those withdrawals stop at one session or continue while price remains pinned below its 200-day trend line.
