Bitcoin derivatives traders are entering September with elevated open interest and diminished confidence, a combination that historically precedes outsized price swings.

Bitcoin futures open interest climbed to $54.82 billion as derivatives traders positioned for heightened volatility heading into September, following a month that saw BTC swing from the low-$60,000s to above $81,000 before retreating below $78,000.
"The market is still in limbo with no clear directional views after a short squeeze due to a record liquidation in leveraged bearish bets on digital assets last week," said Jasper De Maere, OTC trader at Wintermute. "Despite a slight hawkish tilt from Warsh, the market is digesting all of this relatively well so far."
Open interest for Bitcoin futures has not seen a significant recovery after the wipeout, according to Coinglass data. Roughly $3 billion in short positions were liquidated as BTC accelerated from $62,000 to $80,000 in little more than a week. Spot Bitcoin ETFs attracted about $2.5 billion over seven trading sessions, the strongest run since October, per Dow Jones Market Data cited by The Wall Street Journal. Bitcoin slipped as much as 2.9 percent to $77,813 on Friday after Federal Reserve Chair Kevin Warsh pledged to bring inflation back to target, pushing short-term Treasury yields higher.
The $81,000-$83,000 resistance cluster, anchored by the 50-week simple moving average near $81,087, separates a strong recovery from a confirmed trend reversal. A $6.4 billion Bitcoin options expiry on Deribit leaves market makers facing key positioning decisions that could amplify volatility in either direction.
Open Interest Builds as September Approaches
The rise in futures open interest comes at a delicate moment for the market. Bitcoin's August rally — up roughly 28 percent at its peak — was driven by renewed spot ETF inflows, Treasury actions aimed at improving liquidity in the long end of the bond market, concerns about U.S. fiscal sustainability, and forced short covering. But the underlying structure remains contested.
Galaxy Research found that in four of the five completed crypto bear markets, once the 50-week moving average was first broken to the upside, the bear market bottom was definitively in. Bitcoin closed above its 50-week exponential moving average for the first time since November 2025, but the broader 50-week simple moving average near $81,087 has yet to be reclaimed on a weekly basis.
What a Leveraged September Means for BTC
Rising open interest combined with trader uncertainty could produce amplified price swings. If leveraged long positions unwind, the market could face significant downside pressure toward the $75,000-$73,000 support region, where recent market data indicate new capital has entered. Conversely, any positive development — a regulatory breakthrough, sustained ETF inflows, or a dovish pivot from the Fed — could trigger another short squeeze.
Bitcoin traded at $77,813 as of Friday's session, down from an all-time high of around $126,000 reached last October. The 50-week moving average needs to hold on a weekly close for the bullish structure to stay intact, said Mostafa Al-Mashita, co-founder of Secure Digital Markets. "The rally looks structurally healthier than a typical leverage-driven crypto move."
