Bitcoin climbed back above $80,000 this week for the first time since January, but Wintermute says the move is standing on weak footing. In its weekly market report published on May 12, the algorithmic market maker argued that the rally was fueled primarily by forced short covering in perpetual futures rather than genuine spot demand. The firm’s message was blunt: without spot-driven demand, the rally is fragile and vulnerable to a sharp reversal.
Open interest surged while spot activity dried up
The firm pointed to a clear divergence between derivatives and spot markets over the past month. Data cited from NS3.AI showed Bitcoin futures open interest rising from $48 billion to $58 billion, an increase of more than $10 billion. Over the same period, spot trading volume fell to its lowest level in nearly two years.
That gap matters. A price move driven by leveraged positioning and liquidation flows looks very different from one supported by fresh spot accumulation. In Wintermute’s reading, Bitcoin’s break above $80,000 reflected forced rebalancing in the futures market, not broad-based buying from investors in the spot market.
How the short squeeze pushed BTC toward $83,000
Wintermute outlined the mechanics behind the move. As Bitcoin consolidated near $70,000, many traders added short positions, expecting another leg down. Price action then broke higher instead. That put short sellers under pressure, triggered exchange liquidations, and turned closed short positions into market buy orders. The effect fed on itself. As the squeeze spread, Bitcoin moved above its 200-day EMA and briefly reached around $83,000.
The report added that perpetual funding rates remain below normal levels, a sign that bearish positioning may not be fully washed out yet. If Bitcoin breaks above another resistance zone, more short liquidations could still be triggered.
Longer-term signals remain constructive, but chase risk is high
Wintermute did not frame the setup as outright bearish across all time horizons. The report noted that spot Bitcoin ETFs recently recorded about $623 million in net inflows. It also highlighted that Morgan Stanley’s BTC ETF product attracted $194 million within its first month and had not posted a day of net outflows. At the same time, Bitcoin balances on exchanges have dropped to a seven-year low, pointing to continued accumulation by long-term holders.
Those signals support a firmer medium- to long-term picture. Still, Wintermute separated that view from the question of whether current prices offer an attractive entry. The report said a move toward $85,000 remains technically possible, but the present setup does not offer appealing risk-reward, with RSI also approaching overbought territory.
CPI data and Fed leadership remain near-term variables
Macro conditions also remain in focus. The U.S. Bureau of Labor Statistics reported 4% CPI year-over-year growth of 3.8%, slightly above market expectations and enough to revive concerns that inflation is not yet fully under control. The article also cited the Cleveland Fed’s Nowcast model, which had projected 3.56% for April CPI. The actual reading came in nearly 0.25 percentage points higher, keeping the risk of delayed policy easing on the table.
A second uncertainty comes from the nomination of Kevin Warsh as Federal Reserve chair. Because he is widely seen as hawkish, the outcome of that appointment could affect how markets price the future path of interest rates.
The signal Wintermute wants to see is a pickup in spot demand
Wintermute’s central point is not that Bitcoin is about to collapse. It is that the market has not yet shown the kind of spot participation that would make the breakout look durable. ETF inflows and lower exchange balances can support the broader thesis, but they do not immediately repair the near-term gap left by weak spot turnover.
Until spot volume starts to recover in a meaningful way, each fresh push higher may still carry reversal risk. That is especially true in a market where leveraged short exposure has not been fully cleared.
