Bitcoin’s 26% rebound from its mid-august low has carried the market into an $81,000-to-$86,000 zone where several measures point to concentrated selling pressure, even as US spot Bitcoin ETFs posted their strongest weekly net inflow of the year at $2.23 billion.
The rally was initially driven by an unusually sharp unwinding of bearish futures positions. Short liquidations accounted for 85% of all liquidations during the squeeze, while Bitcoin futures open interest measured in BTC fell 11%. That combination indicates much of the move came from traders closing forced or losing short positions rather than from a rapid build-up of new leveraged longs.
Bitcoin reached roughly $80,735 after the squeeze, placing it immediately below resistance levels identified by on-chain cost-basis data, options dealer positioning, liquidation clusters and visible order-book supply. The cluster of indicators makes the $81,000-to-$86,000 range a test of whether spot demand can absorb coins offered by holders who bought at higher prices or have been waiting for an exit point.
Short squeeze reduced leverage rather than adding it
About 86% of modeled liquidation clusters along Bitcoin’s upward path were triggered and absorbed during the move, leaving the largest remaining pockets above the market between $82,000 and $86,000. A separate downside concentration sat between $60,500 and $62,400.
Perpetual swap funding rates remained near neutral during the rebound and occasionally turned negative, a pattern more consistent with reluctant derivatives traders than with broad speculative enthusiasm. Open interest’s nominal dollar value rose mainly because Bitcoin itself appreciated, while BTC-denominated open interest contracted.
That distinction matters for the durability of the rally. A sharp price advance accompanied by rapidly rising open interest and positive funding can signal a crowded leveraged long trade. In this case, the futures market appears to have shed risk as prices climbed. That reduces the immediate danger of a long-liquidation cascade, but it also means the next leg higher would likely need sustained spot buying rather than another large wave of forced short covering.
ETF inflows provide a spot-market counterweight
US spot Bitcoin ETFs recorded $2.23 billion in weekly net inflows without a single daily outflow, according to the figures supplied in the market analysis. The weekly intake was described as the strongest of the year.
Average daily ETF trading volume was about $2.4 billion during the squeeze week. That was approximately half the average seen at the peak of the prior one-to-two-month period and about one-third below the level recorded last august. The figures suggest the fund inflows were substantial, though market-wide ETF trading activity did not match the intensity seen during earlier high-volume phases.
On-chain holding patterns also pointed toward transfers into very large custody-linked entities. Wallets holding between 1,000 and 10,000 BTC reduced their combined balances by about 50,500 BTC from the june 30 low, while the cohort holding more than 100,000 BTC added about 59,100 BTC.
The custody-linked cohort added roughly 31,500 BTC during the short-squeeze week, close to the scale of ETF net creations during the same period. The figures do not establish a coin-for-coin link between whale selling and ETF purchases, but the matching direction and similar magnitude indicate that institutional custody channels absorbed a meaningful share of the supply leaving large private wallets.
Broad accumulation contrasts with narrow token performance
A 30-day accumulation trend score showed all six tracked wallet-size cohorts at or above the neutral 0.5 threshold for 20 consecutive days since aug. 5. The analysis described that as the longest period of cross-cohort accumulation since a 22-day stretch in late 2024.
A cycle composite based on the median of 45 on-chain indicators also rose to the 40 neutral threshold after seven months in “cold” or “cooling” conditions. Comparable extended cooling periods were identified in 2014–2015, 2018–2019, 2020 and 2022–2023.
The improvement was not reflected evenly across the digital-asset market. Larger-cap tokens delivered an average return of about 20.6% over the prior month, close to Bitcoin’s performance, while smaller-cap tokens gained around 6.0%. The gap suggests liquidity has remained concentrated in Bitcoin and the market’s largest assets rather than spreading through more speculative tokens.
Bitcoin also rose about 25% during the squeeze window while the S&P 500 fell 1.7%, pushing the one-month rolling return correlation close to zero. Its negative relationship with the US dollar persisted, though similar episodes of decoupling during 2025 had faded within weeks.
Supply wall meets thinning bids
The overhead barrier begins near $80,800, where an on-chain self-custody cost-basis platform identified a dense cluster of held supply. A dealer gamma flip was estimated near $82,300, meaning options dealers’ hedging activity could become more sensitive to price gains beyond that level.
Liquidation orders extended toward $86,000, while a supply wall was identified from $83,000 to $86,000. Static sell orders placed 100 to 1,000 basis points above the midprice increased about 41% during the final five days of the rally. At the same time, visible bid depth across the order book fell 32% over the final seven days.
Those conditions place greater importance on spot inflows. Bitcoin can continue rising through an offer-heavy range if buy demand remains persistent, but thinner bids leave the market more exposed to abrupt pullbacks if sellers gain control.
Below the market, cost-basis maps identified a buyer-heavy area between $62,000 and $65,000, with nearly two-thirds of that supply attributed to short-term holders. Short-term holder cost basis was estimated near $70,000, creating a nearer level that could shape sentiment if Bitcoin retreats.
Options positioning projected a broad but relatively contained range into late september. The nearest friday expiry carried about $10.4 billion in notional open interest, while the september quarterly expiry held roughly $13.7 billion. About 70% of implied outcomes through sept. 25 fell between $69,000 and $89,700, with the median only slightly above spot. Maximum-pain levels were estimated at $69,000 and $70,000, placing the largest options exposure below the rally’s recent highs.
