U.S. spot Bitcoin ETFs added $1.63 billion final week, bringing four-week web consumption to $3.96 billion and marking 9 optimistic weeks out of the final twelve.
The 12-week rolling sum stands at $6.08 billion, roughly mid-range for 2025 based mostly on CryptoSlate’s inside tracker constructed from fund disclosures and public move tables.
12 months up to now, web inflows whole $22.78 billion, with $58.44 billion since inception.
An assets-under-management proxy is $155.9 billion, whereas the typical weekly worth traded over the previous 4 weeks is $16.17 billion in contrast with a 12-week common of $17.90 billion.
Flows re-accelerated into the flip of the quarter because the coverage and macro backdrop shifted.
The Federal Reserve minimize charges in September, and market pricing tilts to additional easing within the fourth quarter, reducing the hurdle for rate-sensitive allocators that use ETFs so as to add publicity.
The primary day of the U.S. authorities shutdown pushed gold to report highs and the greenback decrease, a cross-asset combine that has traditionally coincided with stronger crypto ETP prints. World product information corroborate the flip.
CoinShares logged consecutive weekly inflows by late September, with Bitcoin capturing nearly all of tickets, and $1.03 billion went into digital asset funds within the week to Sept. 29, together with $790 million into Bitcoin autos. Liquidity stays ETF-centric.
Kaiko Analysis finds that U.S. hours have held a bigger share of depth for the reason that ETF launch and that ETF web flows clarify solely a modest share of day by day BTC returns, with an R² close to 0.32. It is a reminder that derivatives and macro nonetheless drive a big portion of variance.
With This autumn underway, easy situation math frames the trail for web flows and the way a lot Bitcoin could possibly be absorbed from circulating provide.
The previous 4 weeks annualize to roughly $12.9 billion for the quarter, whereas the 12-week run-rate implies about $6.6 billion. The outer bands are offered by the 2025 extremes.
At an illustrative Bitcoin value of $115,000, every $1 billion over a four-week window maps to about 8,700 BTC of web shopping for, roughly 311 BTC per day.
Submit-halving issuance averages close to 450 BTC per day, or roughly 41,400 BTC over a 92-day quarter. The desk under interprets these charges to This autumn totals.
| Situation | Assumption | This autumn web flows (USD) | BTC absorbed at $115k | vs. miner issuance |
|---|---|---|---|---|
| Bull, retouch 2025 greatest 12-week tempo | +$17.1B per 12 weeks | ~+$18.5B | ~161,000 BTC | ~3.9× quarterly issuance |
| Base, maintain final 4-week tempo | +$3.96B per 4 weeks | ~+$12.9B | ~112,000 BTC | ~2.7× |
| Average, revert to 12-week common | +$6.08B per 12 weeks | ~+$6.6B | ~57,000 BTC | ~1.4× |
| Bear, revisit 2025 worst 12-week run | −$4.56B per 12 weeks | ~−$4.9B | ~−43,000 BTC | ≈−1.0× |
Within the Base path, U.S. spot Bitcoin ETFs would retire about 112,000 BTC from float this quarter, or roughly 2.7 occasions new issuance. This magnitude tends to tighten spot availability and maintain foundation supported when threat urge for food is regular.
August’s CPI printed 2.9 % yr over yr, serving to reinforce the disinflation plus easing narrative that underpins allocator demand.
Seasonality provides a behavioral layer, with traders pointing to October’s historic power for crypto.
The rolling 12-week sum of web flows reveals flows falling towards the typical after equaling the 2024 peak in mid July. Thus, latest weekly inflows surpass the present common pattern, indicating a possible reversal in previous patterns.
Nevertheless, if the historic pattern continues, web outflows may attain round $500 million per week by December.
Microstructure continues to evolve round ETF exercise.
Kaiko’s work reveals extra buying and selling clustered round U.S. creation and redemption home windows, and that liquidity throughout these hours carries extra weight in discovery than it did earlier than ETF launch, which helps clarify why value can grind even when move prints are blended.
The correlation framework, with ETF move explaining solely a part of day by day returns, additionally means macro releases, funding, and positioning on CME matter for the day-to-day path. Merchants watching futures open curiosity and quantity can use CME metrics to cross-validate threat urge for food alongside fund flows, with Kaiko’s dashboards offering a consolidated view of depth and spreads throughout venues.
Rotation stays a subplot. U.S. spot Ethereum ETFs have drawn regular allocations since July, and a sell-side replace this week framed ETH as a relative gainer on the margin. Reuters reported Citi lifted its year-end ETH goal and trimmed BTC based mostly on perceived shifts in investor flows.
For now, the U.S. stays the marginal purchaser on this cycle, and CoinShares’ late-September replace confirmed Bitcoin nonetheless dominating weekly tickets throughout world ETPs.
Brief-term dangers focus round information and coverage timing.
The federal government shutdown could delay or distort early-month macro prints, together with nonfarm payrolls and CPI, amplifying narrative swings when traders have fewer anchors.
That makes the ETF tape an much more seen thermometer for threat sentiment as This autumn begins.
If the latest four-week run fee holds, quarter-to-date web consumption would monitor close to $13 billion by year-end.
