US Spot Bitcoin ETFs Post $517.2M Largest Single-Day Inflow Since May

US spot Bitcoin ETFs recorded $517.2 million in net inflows on Wednesday, the largest single-day capture for the Bitcoin fund cohort since May 4 and the third straight session of inflows for the week-to-date. Exchange data confirms the Wednesday print lifted this week’s net total past $1 billion, marking the strongest weekly accumulation since the period ended Jan. 16, when the funds took in roughly $1.42 billion. The move extended August inflows to $1.47 billion and arrived as Bitcoin traded near $72,000. A corresponding $189.2 million flowed into spot Ether ETFs on the same day, pushing their weekly tally to about $291.5 million.

The inflows surfaced as crypto markets rallied in tandem with a US Treasury decision to broaden buybacks of longer-dated government debt, a step that pushed yields and the dollar lower while gold and silver outperformed equities. The regulatory backdrop added to the bid after President Donald Trump urged Congress to advance the CLARITY Act during a White House event. Analysts read the session as a currency-driven rather than growth-driven move, with Bitcoin moving alongside precious metals in what market participants describe as a working debasement trade. The $517.2 million print marks a return of institutional demand after weeks of comparatively subdued flows.

Thursday’s session saw Bitcoin touch $72,659 before easing to $72,606, a 10% 24-hour gain that still leaves the asset 40% below its October record of $126,080. The White House meeting where Trump pressed for the CLARITY Act included Coinbase CEO Brian Armstrong and SEC Chair Paul Atkins, according to attendees. The bill passed the House last year but has been deadlocked; lawmakers now expect a vote in September. BlackRock's iShares Bitcoin Trust has absorbed $588.5 million since Monday, while Morgan Stanley’s Bitcoin Trust also saw notable trading. Separately, the Treasury said it would more than double its government debt repurchases, amplifying the currency-driven bid that has underpinned the sector's rally.

Still, the $1 billion weekly figure is a preliminary reading: SoSoValue data through Aug. 19 excludes two trading sessions yet to close this week, leaving room for the final tally to expand beyond current levels. The jump also marks a decisive turnaround from the prior week, which closed with roughly $389.7 million in net outflows before demand swung back into net inflows. That week-over-week flip suggests institutional buyers are rebuilding exposure rather than making a one-off bet, even as Bitcoin consolidates near the $72,000 level.

(as of 03:23 UTC) COINOTAG’s proprietary 42-indicator composite S/R scoring engine rates the immediate $74,587 resistance at a moderate 59/100, driven by the confluence of low-volume node, R1, RSI overbought and stochastic overbought, while the stronger $76,842 level scores 61/100 on Fibo 0.786. The $70,152 support holds a 51/100 score on a mix of flip resistance→support, Fibo 0.500 and S1, with $68,384 equally weighted on Fibo 0.382, low-volume node, S2 and Supertrend. Funding remains tame at 0.0023% perp, open interest sits at $14.46 billion and the long/short account ratio of 1.10 (52.3% long) shows mild directional length. With RSI at 82.32, MACD bullish and the Fear & Greed Index at 72, momentum firmly favors the bulls, though a daily close below $70,152 would invalidate the breakout thesis.
