Bitcoin’s Resurgence: Spot ETF Inflows Fuel Breakout Past $87,000, But Leverage Looms

Bitcoin (BTC) has recently demonstrated an impressive acceleration in its rally, breaching the significant $86,000 institutional cost zone and briefly touching above $87,000 to mark an eight-month high. Crucially, this upward momentum appears to be more than just a short squeeze; it’s now significantly bolstered by a renewed influx of capital into US spot Bitcoin Exchange Traded Funds (ETFs).

According to Binance’s latest market data, BTC hit a 24-hour peak of $87,363.76 on September 22nd. As of early morning on September 22nd (Taiwan time), Bitcoin was trading around $85,776, still reflecting an approximate 5.2% gain over 24 hours with a robust trading volume of around $58.1 billion. While BTC has seen a slight retreat from its $87,000 peak, it continues to hold firm around the pivotal $85,600 to $86,000 institutional cost area.

Simultaneously, the latest funding data for US spot Bitcoin ETFs has shown a marked increase in strength.

Market tracking data reveals that on September 21st, US spot Bitcoin ETFs collectively recorded approximately $617.6 million in net inflows. This marked the third consecutive trading day of capital accumulation, following net inflows of about $433 million on September 18th and $159.5 million on September 17th. Cumulatively, these three trading days saw a substantial net inflow totaling approximately $1.21 billion.

While previous breakthroughs, particularly between $82,000 and $85,000, were heavily characterized by short covering, the sustained inflows into ETFs suggest the market is entering a more critical phase. The key question now is whether the price surge can transition from being driven by “forced buybacks” to being genuinely propelled by fresh spot capital.

Spot ETFs: From Market Drag to Driving Force

The turnaround in ETF capital flows is particularly noteworthy. Just recently, on September 15th, US spot Bitcoin ETFs experienced a single-day net outflow of approximately $450.4 million, followed by another $295.9 million outflow on September 16th. At that time, the market was clearly under significant institutional withdrawal pressure.

• September 17th: +$159.5 million
• September 18th: +$433.0 million
• September 21st: +$617.6 million

However, the situation reversed dramatically starting September 17th, culminating in a cumulative net inflow of approximately $1.21 billion over three trading days. The $617.6 million inflow on September 21st alone significantly surpassed the previous day’s figure. This indicates that as BTC crossed the $85,000-$86,000 threshold, there wasn’t an immediate, large-scale withdrawal from ETF investors “breaking even.” Instead, current funding data suggests an increase in new buying activity.

Glassnode previously estimated the average cost basis for US spot Bitcoin ETFs to be around $85,600 to $86,000. Bitcoin’s current breach of $86,000 means that a large number of ETF positions, which were previously at a paper loss for several months, are now approaching or entering profitability.

If these investors were simply looking to “break even and exit,” a significant wave of redemptions would theoretically be expected around the $86,000 mark. Yet, the latest ETF data presents the opposite scenario.

Trapped ETF Investors Hold, New Funds Chase – But Leverage Returns

This shift alters the market’s most pressing question. Previously, concerns revolved around whether “trapped” ETF investors would collectively liquidate their positions once BTC returned to their average cost. The initial answer appears to be: “Not yet, at least.” The recent three consecutive days of ETF inflows suggest that the $85,000 to $87,000 range is not merely a “break-even selling zone,” but rather a region attracting new institutional allocation demand.

Bitbo tracking data further shows that as of September 21st, US spot Bitcoin ETFs collectively hold approximately 1.263 million BTC, valued at about $109.2 billion at the time, representing roughly 6.0% of Bitcoin’s maximum supply of 21 million coins. BlackRock’s IBIT alone holds about 786,000 BTC, while Fidelity’s FBTC holds around 177,000 BTC. Recent changes in holdings further indicate that on September 21st, IBIT’s BTC holdings increased by approximately 1,336 BTC, and FBTC’s by about 3,827 BTC.

Following this breakthrough past $86,000, at least some major ETFs are not reducing their holdings but are actively increasing their BTC exposure. This makes the market structure healthier than a mere “short squeeze.”

However, stronger ETF buying doesn’t necessarily imply reduced market risk. Coinalyze data points out that since BTC broke above $82,000 overnight, traders have added over $2 billion in new Bitcoin futures exposure, pushing the total open interest (OI) to over $31 billion.

An increase in OI signals that the market is once again employing leverage to bet on future price movements, encompassing both long and short positions. When price rises alongside increasing OI, it typically suggests that new leveraged capital is entering the market to establish directional positions, rather than just old positions closing out. While this can fuel further price continuation, it also heightens the risk of cascading liquidations during the next significant price fluctuation.

Futures OI Surpasses $31 Billion Post-$82K Breakout

BTC’s journey from approximately $82,000 to $87,000 represents a gain of about 6%. Yet, during the same period, the market added over $2 billion in futures positions. This indicates that after the initial short squeeze, investors chose not to broadly reduce leverage but instead re-entered with increased bets.

This dynamic was evident in the early trading hours of September 21st. CoinGlass data shows that around the time BTC broke above $85,000, approximately $750.5 million in leveraged positions were liquidated across the entire market within 24 hours. Of this, about $648 million, or 86%, were short positions, with Bitcoin itself accounting for around $360 million in liquidations. Later data even revealed that as BTC continued its ascent, the total scale of short liquidations across the crypto market further increased, with Bitcoin shorts making up a significant proportion.

In essence, the initial phase of this rally was indeed driven by a short squeeze. However, the real risk now is whether long positions will begin to accumulate excessive leverage after the shorts have been flushed out.

Why is the $87,000 Breakthrough More Significant Than $85,000?

When BTC first broke above $85,000 the previous day, a lingering question was whether “someone was genuinely buying” or if “shorts were simply being forced to cover.”

At that time, a striking data point was Binance’s net taker volume, which surged from approximately $11 million to $618 million within about an hour, indicating a sudden influx of aggressive buy orders.

The latest single-day net inflow of approximately $617.6 million into spot Bitcoin ETFs on September 21st, while numerically very close, represents a fundamentally different market dynamic. The former reflects short-term aggressive buying on exchanges, while the latter signifies traditional financial markets increasing Bitcoin exposure via ETFs. The true significance of this rally lies in the simultaneous emergence of both these powerful forces.

Another technical shift in Bitcoin’s current rebound is its reclaim of the 50-week moving average for the first time in approximately ten months. This long-term moving average is considered a crucial indicator for discerning major cycle structures. While BTC’s breakthrough past $86,000 to an eight-month high, with multiple spot Bitcoin ETF prices simultaneously breaking technical levels, is positive, the moving average breakthrough itself doesn’t guarantee an uninterrupted upward trend. The more critical factor remains whether capital is willing to stay in the market after the breakthrough.

And the current $617.6 million in ETF net inflows provides precisely the validation signal this rally needs to see.

$85.6K Cost Wall Breached: Can It Turn Into Support?

The most important market question in the previous phase was whether BTC could reclaim the average cost basis of ETF investors. Now that the price has achieved this, it signifies that the overall institutional cost zone for US spot ETFs, roughly $85,600 to $86,000, has been breached intraday. Glassnode research suggests that if BTC can consistently hold above $86,000, it would indicate that the previous ceiling of large institutional cost is being absorbed by the market.

The next key observation, therefore, is no longer just “can it break through,” but whether the $85,600 to $86,000 range can successfully transition from resistance to support. If the price pulls back and finds strong buying interest in this area, it would signal that the previously “trapped” supply has been genuinely digested. Conversely, if BTC quickly falls back below $85,000, and ETF inflows simultaneously weaken, this breakthrough might still be predominantly a short squeeze rather than the beginning of a new trend.

BTC Retreats From $87K: Initial Profit-Taking Emerges

Bitcoin did not continue its linear ascent after touching $87,363. Binance data for Asian morning trading on September 22nd shows BTC retreating from its 24-hour high of $87,363.76 to approximately $85,776. Real-time indices also indicate that BTC briefly returned to around $85,600 during Asian trading hours on September 22nd, after surging from about $81,165 to a high of $87,374 on September 21st.

This suggests that an initial wave of profit-taking has begun around the $87,000 mark. However, the current pullback is merely retesting the $86,000 area and is not yet sufficient to negate the earlier breakthrough. Instead, this retest can be viewed as the market’s first true stress test: “Are new ETF funds willing to buy in the $85,000 to $86,000 range?”

From a market psychology perspective, $90,000 is undoubtedly a very prominent psychological barrier. However, from a structural viewpoint, three lines may be more crucial to track:

1. The first is $85,600 to $86,000. This is the previous ETF average cost zone and currently the most important short-term support test.
2. The second is around $87,300. This is the latest 24-hour high, and a breakthrough here would signal the market creating a new high.
3. The third is $90,000. If BTC can break $90,000, the market will enter another psychological price bracket, and some short positions above this level may be forced to cover, providing additional buying pressure.

However, if OI continues to increase rapidly before breaking $90,000, risks will simultaneously escalate. The healthiest scenario would be: price rises, ETF buying continues, but leverage doesn’t increase too quickly. This is where the current market presents a contradiction: good news from returning spot funds, but also the rapid return of leverage.

Since BTC broke out from $82,000, futures OI has increased by over $2 billion, pushing the total scale past $31 billion. Therefore, for bulls, the ideal scenario isn’t BTC immediately surging to $90,000 or even $92,000 with high leverage. Instead, it would be for the price to consolidate within the $85,000 to $87,000 range for a few days, with ETFs maintaining net inflows, but futures OI and funding rates not overheating too quickly. This would allow the rally to gradually transition from being “liquidation-driven” to “spot demand-driven.” Conversely, if OI continues to rise vertically before the $90,000 breakthrough, and ETF inflows begin to weaken, newly established long leverage could become the fuel for the next wave of liquidations.

From “Trapped Zone” to “Chase Zone”: $86,000 Completes Its First Role Reversal

Just three days ago, the market was debating whether Bitcoin could break through the corporate treasury cost of approximately $80,500. A day ago, the question shifted to whether it could overcome the ETF cost of about $86,000. Today, BTC has briefly reached $87,363, and ETFs have seen a single-day inflow of approximately $618 million. The market’s question has therefore changed again: “Now that ETFs are back in profit, how much more are new funds willing to pay at higher prices?”

At least the first day’s answer leans positive.

However, the additional $2 billion in leverage in the futures market serves as a reminder to investors: this rally is rapidly transitioning from an “undervalued rebound” to a phase where “the market is beginning to re-price.”

The biggest risk in a re-pricing phase is often not a lack of buying interest, but rather buying interest and leverage increasing too quickly simultaneously. Therefore, while $90,000 is the next most prominent psychological barrier, the true determinants of whether this rally can be sustained remain two sets of data: whether ETF net inflows can continue, and whether the pace of futures OI growth can moderate.

If the former continues to increase and the latter stabilizes, $87,000 may just be a midpoint in a new trend. If the situation reverses, a leverage flush might occur before $90,000 is even reached.
