US Spot Bitcoin ETF Flows Turn Sharply Negative — Week of July 7–13, 2026
Editor's note: this inaugural recap is seeded from bryptoflows' local development dataset to establish the weekly format ahead of the first fully live edition. Treat the figures below as illustrative of the article's structure rather than as a current market report — the automated routine that replaces this note publishes fresh, live numbers every Saturday night.
The week in flows
US spot Bitcoin ETFs shed $493.0M net over the five sessions through July 13 — an average of -$98.6M a day, and $46.5M per session worse than the five sessions before it. Momentum, in other words, wasn't just negative, it was deteriorating.
Almost all of the damage landed in a single session. July 13 alone accounted for -$424.7M, roughly 86% of the week's entire net outflow, and it broke the pattern that has defined this cycle: BlackRock's IBIT, the fund that has otherwise absorbed more net inflow than the rest of the category combined, posted a -$185.5M outflow of its own that day — its worst showing in weeks. Fidelity's FBTC was worse still, at -$245.6M, the single largest line item of the session. Grayscale's GBTC added another -$53.1M, partially offset by +$53.4M into Grayscale's newer BTC "mini" trust and a small +$6.1M into VanEck's HODL — the only product that closed the day green.
Breadth confirms this wasn't a broad, category-wide rotation so much as a narrow, concentrated air-pocket concentrated in the two largest funds: only 2 of 12 reporting products closed the latest session positive, a 16.7% breadth reading. Pulling back to the 20-session window, net flow sits at -$2,682.3M, and the move is statistically unusual against the category's own two-year history — a -1.67σ flow z-score puts the latest reading in roughly the bottom 6% of all sessions since spot ETFs launched in January 2024. In plain terms: the z-score measures how far the latest rolling flow sits from its own recent average, in standard deviations — a reading past -1.5σ or so shows up only a handful of times a year, which is what makes this week worth flagging rather than shrugging off as ordinary chop.
For scale, this is nowhere near the record: the single worst day on record remains February 25, 2025, at -$1,113.7M, and the best remains November 7, 2024, at +$1,373.8M. July 13 doesn't rewrite the history books — but a -1.67σ reading is rare enough that it's worth watching for follow-through rather than dismissing as noise.
Where the outflows are concentrated
Life-to-date, the category's flow picture is still dominated by two funds pulling in opposite directions. BlackRock's IBIT has absorbed +$60.1B net since inception — a 59.8% gross share of all category volume, and on its own more than the entire complex's net inflow — while Grayscale's legacy vehicles (GBTC plus its newer BTC "mini" trust) have shed a combined -$24.8B, by far the category's largest drag. Fidelity's FBTC (+$9.9B) and Bitwise's BITB (+$2.0B) round out the next tier of net absorbers, with ARK 21Shares' ARKB (+$1.25B) and VanEck's HODL (+$1.14B) close behind.
The smaller end of the category is worth naming too, even if the dollar figures are modest: Morgan Stanley's MSBT (+$408M) is the newest entrant and already net-positive since launch; Valkyrie's BRRR (+$329M), Franklin Templeton's EZBC (+$328M), Invesco Galaxy's BTCO (+$165M), and WisdomTree's BTCW (+$96M) round out the field. None of them move the category total meaningfully on their own, but they're a reasonable cross-check on breadth — when even these smaller funds go quiet, as they did this week, it confirms the softness wasn't isolated to one or two names.
None of the smaller ten funds posted a positive session on July 13 either, which is the detail that separates a genuinely broad risk-off session from an IBIT-specific wobble. In a category this concentrated, it's common for the smaller funds to sit out a quiet day regardless of direction — simply because their reporting flow is thinner and lumpier week to week. Seeing all ten go quiet on the same day the two largest funds turned negative is a mildly stronger signal than either fact on its own.
What stands out about this particular week is how broad-based the softness was among the funds that normally move the needle. Every issuer except VanEck's HODL — on a 3-day positive streak, the lone green shoot in the data — closed the period flat or negative. Product concentration (HHI 0.40) and issuer concentration (HHI 0.43) both sit high enough that a wobble in IBIT alone can usually swing the whole category one way; this week, it wasn't only IBIT.
Zooming out
Despite the drawdown, the category remains a substantial net absorber of Bitcoin since inception. Cumulative net flow stands at +$50.9B, down from a $62.7B peak reached earlier in the cycle — an $11.8B, or roughly 19%, retracement from the high-water mark. That's a meaningful pullback, but it's a pullback from a peak, not a reversal into net redemptions for the category as a whole.
The period-total figures put the week in sharper relief: month-to-date net flow (-$299.8M) and quarter-to-date net flow (-$299.8M) are identical, which means essentially all of this quarter's net damage to date arrived inside the single week covered here. Year-to-date net flow stands at -$5,689.6M — a reminder that even a category with a multi-billion-dollar cumulative cushion can still be running behind for the year.
Strategy adds 203,000 BTC in a single filing
The period's other headline sits on the opposite side of the demand ledger. Strategy's July 18 8-K disclosed the acquisition of 202,967 BTC for roughly $16.5B, at an average price of $81,294 — pushing total holdings to 843,775 BTC against a $63.69B aggregate cost basis ($75,476 average cost per coin).
For scale: the five weekly filings before it added 6,911, 11,145, 15,670, 21,021, and 12,017 BTC respectively. This single filing is larger than those previous five combined. It's a genuine outlier against the company's own recent cadence, and it lands in the same window as the ETF category's worst week in months. Whether that's coincidence, a rotation of institutional demand from fund wrappers toward direct corporate treasury exposure, or simply Strategy's own capital-raising calendar catching up with itself is exactly the kind of question the next few weeks of data should start to clarify — worth flagging as an open question rather than a conclusion this early.
Financing the accumulation
Strategy funded part of the period through its at-the-market common stock program, netting $263.5M from 2.73M shares sold. Its four preferred stock programs — STRC, STRD, STRF, and STRK — saw zero issuance this period but carry a combined ~$25.2B of remaining available capacity, against ~$48.8B available across all five programs together. Dry powder isn't the constraint on further accumulation here; deployment pace is the only open variable.
What to watch next week
- Whether breadth recovers past 2 of 12 products, or the outflow stays this concentrated in the two largest funds.
- Whether the negative streak — just one day old as of this writing — extends or reverses at the next reporting session.
- Whether Strategy's acquisition pace reverts toward its recent weekly average, or another outsized filing follows the July 18 print.
- Whether the flow z-score, currently pinned near a two-year low, mean-reverts the way statistically stretched readings typically do.
