Bitcoin futures open interest fell by $1.4 billion in the week through October 4, 2026, while spot taker flow shifted from net selling to net buying. The combination points to a mixed market snapshot—not proof of a lasting reversal: long-side funding payments rose, short-term capital measures edged higher, and US spot ETF inflows slowed sharply but stayed positive.
What changed in the week to October 4?
Glassnode’s BTC Market Pulse: Week 41, published October 5, 2026, recorded changes across futures, spot trading, on-chain indicators, and US spot ETFs. Those measures track different parts of the market, so they should not be compressed into a single bullish-or-bearish signal.
| Measure | Reported change | What it indicates |
|---|---|---|
| Aggregate Bitcoin futures open interest | $38.0 billion to $36.6 billion, down 3.8% (Glassnode, week to October 4, 2026) | Less nominal outstanding futures exposure; not a direct measure of account-level leverage |
| Spot cumulative volume delta (CVD) | -$102.8 million to +$33.2 million (Glassnode, week to October 4, 2026) | A shift in aggressive spot taker flow from net selling to net buying |
| Long-side funding payments | $926,400 to $1.5 million (Glassnode, week to October 4, 2026) | Higher funding payments associated with long positions, even as open interest declined |
| Hot Capital Share | 18.9% to 19.5% (Glassnode, week to October 4, 2026) | A larger share of capital recently active, according to Glassnode’s metric |
| Short-term-to-long-term holder supply ratio | 13.7% to 14.2% (Glassnode, week to October 4, 2026) | A higher relative presence of supply attributed to short-term holders |
| Weekly US spot Bitcoin ETF netflow | $208.1 million, down 87.7% from the previous week; still positive (Glassnode, week to October 4, 2026) | Net inflows continued, but at a much slower pace |
What does the $1.4 billion futures decline mean?
Open interest is the aggregate value of outstanding futures contracts. The decline from $38.0 billion to $36.6 billion means that measure of nominal exposure contracted by 3.8% over the reporting week. Glassnode described the move as cooling speculative appetite and positions being unwound, while noting that open interest remained near its high band and aggregate leverage remained elevated relative to its statistical range.
That does not establish why specific positions closed or how vulnerable the remaining positions are. Aggregate open interest does not reveal account-level leverage or collateral; assessing that risk requires information the aggregate figure does not provide. Glassnode’s derivatives metrics documentation describes the relevant market measures, but the weekly total is not a view into individual accounts.

Did spot buyers step in?
In the limited sense measured by spot CVD, yes: the metric moved from -$102.8 million to +$33.2 million. Glassnode interprets that shift as aggressive spot taker flows changing from net selling to net buying. CVD reflects the balance of trading aggression; it does not prove new investor capital or fresh fiat entering Bitcoin.
The change also came without a rise in reported daily spot volume: Glassnode’s figure edged down from $6.0 billion to $5.9 billion. The CVD reading supports a recovery in short-term buyer conviction, but Glassnode said it remained within its range. Neither that reading nor the volume figure establishes that buying will continue.

Why rising funding matters alongside falling open interest
Long-side funding payments increased from $926,400 to $1.5 million as aggregate open interest fell. Glassnode said funding remained within its statistical boundaries; it did not characterize the increase as an extreme imbalance. The two measures therefore tell different parts of the story: aggregate futures exposure contracted, while this measure of payments associated with long positions rose.
It would be misleading to describe the week simply as bullish leverage being wiped out. The data do not show that remaining futures positions are safe, nor do they establish the market’s next direction.

What the on-chain indicators add—and what they cannot prove
Glassnode reported Hot Capital Share rising from 18.9% to 19.5%, a 3.1% increase, and the short-term-to-long-term holder supply ratio moving from 13.7% to 14.2%, a 4.2% increase. These indicators add evidence of a greater recent or short-term capital and holder presence. They do not count every new buyer, show that the coins are being sold, or prove that all recently active supply has entered the market.
Glassnode explains the holder-supply measure in its long- and short-term holder supply guide and its realized-cap age-band guide. These are cohort and activity lenses, not a direct census of new investors.

ETF flows are a counterweight to the stronger spot-flow reading
Weekly US spot ETF netflow was $208.1 million, still positive but 87.7% lower than the prior week. ETF trade volume also fell 11.8% to $10.8 billion, according to Glassnode for the week to October 4, 2026. Positive netflow means inflows exceeded outflows over the measured period; the sharp slowdown does not indicate a fresh surge in demand.
The ETF figures cover US spot products and should not be treated as a complete measure of global Bitcoin demand. Taken with the CVD change, they show why the snapshot is mixed: spot taker flow improved, but another demand measure weakened substantially.

What to watch next
The useful follow-up is whether positive spot CVD and positive net ETF flows persist while active supply is absorbed. A single week cannot answer that. Renewed spot taker selling or weakening holder profitability would make the demand picture more fragile; sustained buying alongside continued positive netflows would provide stronger evidence that demand is holding up.
Glassnode states that its data are informational and educational, not a basis for investment decisions. It also cautions that exchange-balance estimates rely on address labels and proprietary clustering and may miss reserves at exchanges that do not disclose addresses. Those limits matter when interpreting aggregate on-chain indicators as well as derivatives totals.
