Bitcoin Rally Meets a Key $81K–$86K Supply Wall After Biggest Short Squeeze Since 2019

Bitcoin's August rebound is approaching what analysts describe as its most consequential technical and on-chain hurdle so far: a heavy supply band between $81,000 and $86,000 that could shape whether BTC can push toward its early-2026 highs. BTC was trading around $80,000 on Thursday after the rally gained traction following the US Treasury's expanded buybacks of long-dated bonds. The move has briefly lifted Bitcoin above $81,000 this week, extending gains supported by falling yields, a softer dollar and renewed appetite for scarce assets. Glassnode flags the zone overhead as the market's main decision area. Supply builds as holders return to breakeven A first pressure point sits near $80,800, where a sizable pool of self-custodied Bitcoin is moving back toward breakeven. Long-term holders who have sat through months of drawdowns may be more inclined to sell once positions return to flat. Derivatives positioning could add friction. Glassnode estimates dealer hedging dynamics begin to shift around $82,300, which may amplify sell-side flows if price climbs further. The same area also contains a dense cluster of short-liquidation levels remaining after last week's squeeze. That surge triggered the largest short-liquidation event since 2019 and cut futures open interest by 11% in BTC terms. It follows an earlier breakout above $72,000, when more than $3 billion in bearish positions were liquidated as Bitcoin cleared key resistance. The squeeze helped translate improving spot demand into a sharper move higher. ETF inflows strengthen the demand backdrop This advance has not been fueled solely by leverage. Institutional participation has picked up, with US spot Bitcoin ETFs posting more than $2.8 billion in net inflows over eight straight sessions, according to Glassnode. Wallet accumulation increased as BTC moved off exchanges. The rebound in ETF demand surfaced earlier in the upswing. Bitcoin funds saw their strongest inflows since May as BTC reclaimed $69,000, while larger Treasury bond-buyback operations helped ease financial conditions. Since then, renewed ETF buying has become one of the rally's more durable supports. For bulls, Glassnode says a sustained break above $83,300, paired with continued ETF inflows, would indicate overhead supply is being absorbed. Until then, the $81,000–$86,000 band remains the clearest test of whether Bitcoin's rebound can evolve into a broader recovery.
