Bitcoin futures open interest fell by $1.4 billion in the week through October 4, 2026, while spot taker flows turned from net selling to net buying. That is a more constructive spot-flow reading, not proof of a lasting reversal: long-side funding rose, short-term capital indicators increased, and US spot Bitcoin ETF inflows slowed sharply while remaining positive.
What changed in Bitcoin markets during the week
Glassnode’s BTC Market Pulse: Week 41, published October 5, 2026, compares market readings for the week through October 4. It shows different signals across derivatives, spot trading, on-chain cohorts, and US spot ETFs; they should not be treated as one measure of investor sentiment.
| Measure | Weekly change | What it indicates |
|---|---|---|
| Aggregate Bitcoin futures open interest | $38.0 billion to $36.6 billion, down 3.8% | Less nominal outstanding futures exposure; not a direct measure of account-level leverage or collateral. |
| Spot cumulative volume delta (CVD) | -$102.8 million to +$33.2 million | A shift in aggressive spot taker flows from net selling to net buying. |
| Long-side funding payments | $926,400 to $1.5 million | Higher payments by long positions for perpetual exposure, even as aggregate open interest declined. |
| Hot Capital Share | 18.9% to 19.5% | A larger share of capital classified as recently active. |
| Short-term-to-long-term holder supply ratio | 13.7% to 14.2% | A higher share of supply attributed to short-term holders relative to long-term holders. |
| Weekly US spot ETF netflow | $208.1 million, down 87.7% from the prior week | Net inflows remained positive, but were much smaller. |
What the futures decline does—and does not—show
Open interest is the aggregate nominal value of outstanding futures contracts. Its fall from $38.0 billion to $36.6 billion indicates a contraction in that exposure, but the figure alone cannot show why positions were closed, how much leverage individual accounts used, or what collateral supports them. As CryptoSlate’s October 6 coverage notes, account-level leverage and collateral matter when judging position vulnerability.
Glassnode describes the decline as cooling speculative appetite and positions being unwound, while noting that open interest remained near its high band and aggregate leverage was still elevated relative to its statistical range. A lower open-interest figure therefore should not be read as proof that the market is fully deleveraged or that remaining positions are safe.

Spot buyers returned, but volume did not rise
Spot CVD moved from -$102.8 million to +$33.2 million, which Glassnode interprets as aggressive spot taker flow changing from net selling to net buying. CVD tracks the balance of buyers and sellers acting as takers; it does not establish that new investor capital or fiat entered the market.
The improvement was also not accompanied by higher reported daily spot volume: Glassnode’s figure edged down from $6.0 billion to $5.9 billion. The CVD reading remained within its range, so it supports a recovery in short-term buying conviction without confirming that the shift will continue.

Why rising funding complicates a simple “leverage washed out” story
Long-side funding payments rose from $926,400 to $1.5 million as futures open interest fell. These are compatible movements: aggregate outstanding exposure can contract while long demand for perpetual exposure increases on the funding measure. Glassnode says long-side funding stayed within its statistical boundaries, rather than describing an extreme imbalance.
Funding is a derivatives-market signal, not a guarantee of direction. Its increase is a reason not to characterize the week as only bullish leverage being removed; it also does not by itself show that long positioning has become dangerously crowded.

What the on-chain cohort measures add
Hot Capital Share increased from 18.9% to 19.5%, and the short-term-to-long-term holder supply ratio rose from 13.7% to 14.2%. Glassnode uses these measures to describe a greater presence of recently active and shorter-term capital or supply.
They are cohort and activity indicators, not a count of newly onboarded investors. A higher short-term-holder share does not prove that those coins are being sold. Glassnode’s documentation explains the relevant concepts in its guides to realized-cap age bands and long- and short-term holder supply.

ETF inflows remained positive but lost momentum
Weekly US spot Bitcoin ETF netflow was $208.1 million, an 87.7% decrease from the previous week. ETF trade volume also fell 11.8% to $10.8 billion. Netflow was still positive, but the sharp decline is a counterweight to the improvement in spot CVD—not evidence of a fresh surge in institutional demand.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What would make the spot-demand signal more convincing?
The useful test is whether positive spot taker flow and positive ETF netflows persist while active supply is absorbed. One weekly snapshot cannot establish that absorption or determine Bitcoin’s next move. Renewed spot taker selling or weakening holder profitability would make the more fragile interpretation harder to dismiss.

Glassnode says its market data is informational and educational, not a basis for investment decisions. Its exchange-balance figures also rely on address labels and proprietary clustering, which may not capture all exchange reserves where addresses are undisclosed. For futures open interest, the separate limitation is that aggregate totals do not reveal each account’s leverage or collateral. Glassnode’s derivatives metrics documentation describes the derivatives data category.
