Glassnode’s liquidation map put Bitcoin’s largest overhead cluster of vulnerable short positions near $90,000, while BTC was trading around $85,000–$86,000 on Oct. 4, 2026. That made $90,000 a potential pressure point: if price reached the cluster, forced short closures could add buying to the move. It did not mean Bitcoin was certain to reach that level.

How a short squeeze can accelerate a move
A short position makes money if the asset’s price falls. If Bitcoin instead rises far enough, a leveraged short may be forced to close. Closing a short involves buying back Bitcoin, adding demand as the price rises. If that buying pushes price into more liquidation thresholds, further forced closures can intensify the move.

The effect can work in the other direction, too. If Bitcoin falls into a cluster of leveraged long positions, forced closures can add selling pressure. Glassnode’s reported map showed smaller clusters below the market near $83,000 and $75,000.

Price levels to watch around the map
The $90,000 zone was the largest overhead cluster in the report, but it was not the only level traders were watching. The same coverage noted smaller clusters near $83,000 and $75,000, with shorter-term levels around $84,000 and $85,700. It also identified a recent local range between roughly $82,500 and $87,500.

Bitcoin had also recently met selling pressure around $87,000, making that area an intervening test on the way to the larger $90,000 cluster—not a guarantee of what would happen next.

What previous liquidation events show—and what they don’t
In September, Bitcoin’s move above $85,000 coincided with substantial short liquidations across crypto markets. That episode illustrates how forced buying can contribute to a rally, though liquidation figures vary by source and market coverage.

Glassnode also described a record short-liquidation event in mid-August that helped ignite a roughly 26% rebound from the low. The rally then ran into a concentration of supply around $81,000–$86,000, a reminder that short covering can fuel a move without guaranteeing that it will continue.

Why a liquidation heatmap is not a price forecast
A heatmap estimates where leveraged positions may be at risk of liquidation; it does not show a guaranteed future path for Bitcoin. Glassnode describes its futures heatmap as a model that uses recent open-interest flows and price moves to estimate likely liquidation exposure across price levels.

The estimate depends on the data, exchanges, and lookback window used. Glassnode’s methodology notes that its liquidation metrics draw on positions tracked on Hyperliquid, while its futures heatmap describes estimated exposure from perpetual-futures data.
