Bitcoin's Rebound Near $86,000 Draws Spot Buyers as Leverage and ETF Outflows Build

Bitcoin's 11.65% rebound over the past week has drawn in genuine spot and on-chain buyers, broadening a rally that began largely as a squeeze on short sellers, according to CryptoSlate.

The recovery has also rebuilt leverage and profit-taking, however, while exchange-traded funds continued to record net outflows.

From squeeze to spot demand

CryptoSlate market data put Bitcoin at $85,877 during European trading hours on 22 September. Glassnode's latest market snapshot showed a gain of more than 10% from the prior Sunday's close, which lifted the price back over $80,000, a level it had not reached in almost two weeks.

The first leg of the move was largely mechanical. When Bitcoin broke above $85,000 on 21 September, CoinGlass data showed more than $648m of crypto short positions were liquidated. Traders who had bet on falling prices were forced to buy back their positions, adding momentum to the advance.

Forced buying of that kind runs out once vulnerable positions are cleared. The question the rally left behind was whether willing buyers would stay once the squeeze faded.

Signs of genuine participation

Glassnode's data suggests they have, at least so far. On exchanges, spot taker flow turned from net selling into net buying while volume increased, and the monthly change in realised capitalisation moved above its upper band.

Realised capitalisation values each coin at the price at which it last moved on-chain, so it is best read as an estimate of the market's aggregate cost basis rather than a literal measure of cash coming in. The metric had contracted on 15 September after 27 consecutive days of growth, according to an earlier CryptoSlate report.

Taker flow in perpetual futures shifted in the same direction, with heavy net selling giving way to net buying. That reflects derivatives positioning, though, rather than spot purchases.

Leverage and fund outflows

Better demand has come with a new vulnerability. Futures open interest, funding and realised profit-taking all sat above Glassnode's bands.

Elevated funding means traders holding long positions are paying to keep them open, a sign of crowded bullish positioning. Options open interest was also above its upper band, at close to $41bn.

The spread between implied and realised volatility fell below its lower band, meaning options were pricing in less movement than Bitcoin had recently delivered. Skew leaned towards puts but stayed within its normal range.

About two-thirds of Bitcoin's supply was in profit, which gives holders room to sell into strength.

The fund channel has not confirmed the recovery either. Glassnode's 21 September report put weekly ETF net flows at roughly minus $300m.

That divergence matters. Buying on exchanges has improved, but a major route for institutional demand was still losing capital during the rebound. If fund outflows persist while leverage keeps rising, the advance would rest more heavily on derivatives traders than on longer-term capital.

What to watch

The next test is whether spot buying holds as funding cools. If spot participation can absorb leveraged longs and sales from holders sitting on gains, the move has a firmer base.

If it cannot, crowded positioning combined with relatively cheap options leaves room for a sharp reversal in either direction.

Deribit's Bitcoin options expiry on 25 September at 08:00 UTC is the next near-term marker, with the potential for hedging flows and higher volatility around it. Weekly ETF flow figures will show whether fund investors start to follow exchange buyers back into the market.
