Bitcoin (BTC) Holds $83K as ETFs Record Best Weekly Inflow of 2026

TLDR

• BTC hovers around $83,150 following a retreat from recent highs above $87,000.
• Spot Bitcoin ETFs in the U.S. recorded approximately $2.39 billion in inflows last week—the best weekly performance of 2026.
• Bitcoin is currently challenging ascending trendline support in the $82,000-$83,000 region on daily charts.
• Technical indicators show RSI at 59.54 with MACD remaining positive, indicating momentum has slowed but remains intact.
• Elevated Treasury yields and hawkish rate expectations continue to limit upside potential in the short term.

Bitcoin was trading around $83,150 on Sunday following another rejection near the $85,000 level. Market participants are closely watching whether bulls can maintain the upward trend established since August.

Bitcoin (BTC) Price

BTC started the session near $84,463 and climbed to an intraday peak of $84,992 before declining to $82,675. The daily candle registered approximately a 1.6% decline.

This downturn comes after last week’s failure to sustain momentum above $87,000. Bitcoin reached approximately $87,350 in September before encountering significant selling pressure that drove prices back toward the low-$80,000 territory.

However, BTC remains significantly elevated compared to its August trough near $63,000. Highlighting this resilience, trader Bull Theory (@BullTheoryio) noted that Bitcoin had secured a close above $84,000, marking its highest weekly finish in eight months, while emphasizing that BTC has rallied 45% from its June bottom.

Bitcoin Challenges Ascending Trendline Near $83K

The critical question facing traders is whether BTC can maintain support above its ascending trendline. Price action is currently testing a demand zone spanning $82,000 to $83,000 that has consistently attracted buying interest throughout September.

A breakdown beneath this trendline could expose Bitcoin to a move toward $75,000-$77,000. A more substantial support area exists further below in the $65,000-$67,000 range.

For the upside scenario, bulls must first recapture $85,000. Following that, a decisive break above $87,000-$88,000 would shift focus to resistance near $94,000-$97,000.

Technical momentum has decelerated but maintains a constructive bias. The daily RSI registers 59.54, positioned above neutral territory but below overbought conditions. The MACD indicator also shows modest bullish signals, with the MACD line at approximately 2,285 versus a signal line around 2,232.

Crypto analyst Benjamin Cowen (@benjamincowen) provided his perspective on market structure. He observed that BTC closed above its May peak, which favors bullish scenarios, and stated that bears now carry the burden of proof. However, he noted the rally has been more subdued compared to previous cycles, when BTC typically surged 20-30% within one to two weeks following similar breakouts, suggesting seasonality concerns and rising yields may be restraining price action.

ETF Inflows Hit 2026 Peak

The most significant bullish catalyst has emerged from spot Bitcoin ETF demand. These investment vehicles captured approximately $2.39 billion during the week of Sept. 21-25, representing the largest weekly accumulation of 2026.

Friday’s session contributed $134.5 million, marking the seventh consecutive day of positive flows. BlackRock’s IBIT product dominated with $97 million in inflows, while Fidelity’s FBTC contributed approximately $49 million.

This sustained inflow streak has returned 2026 ETF flows to net positive territory following substantial net outflows earlier this year. The divergence between strong ETF demand and sideways price action suggests fresh capital is being absorbed by existing holders distributing in the $84,000-$87,000 zone.

U.S. Treasury yields have climbed to their highest levels since 2007 as market participants anticipate additional Federal Reserve rate increases. Bitcoin continues to trade near $83,150, positioned directly above its ascending daily trendline support, with bulls requiring a reclaim of $85,000 followed by $87,000-$88,000 to resume the upward trajectory.
