Bitcoin has climbed to a new high of $81,000, coinciding with an unusual signal from the derivatives markets: the longest continuous period of negative funding rates seen in the past decade.
The top cryptocurrency is up by 2.9% over the last 24 hours and currently trades around $81,250, according to CoinGecko data.
For 66 consecutive days, the 30-day average funding rate for Bitcoin perpetual swaps—which track Bitcoin’s spot price without an expiry date—has stayed negative, as reported in a tweet by Vetle Lund, head of research at K33 Research, on Monday.
This marks the longest streak of negative 30-day average funding rates this decade. “I’m focused on this regime for one simple reason: timing,” Lund stated. “Persistent negative funding rates have historically signaled optimal buying opportunities with conviction.”
The negative funding situation means that short positions pay longs a daily fee to maintain the contract’s price relative to the spot rate, a cost that compounds over time.
During this period, Bitcoin has seen a 12% rally in April, prompting the question: is the ongoing negative funding indicative of genuine market fear or something more structural? Derek Lim from Caladan suggests it reflects institutional supply mechanisms rather than bearish sentiment. “Funding rates indicate flows, not sentiments, especially when markets are dominated by institutions,” he told Decrypt. The continuous negative funding appears to stem from structured short supply sources including hedge funds managing investor redemptions, basis traders exploiting equity premiums through delta-neutral strategies, and miners hedging as they transition towards AI compute.
U.S. spot Bitcoin ETFs experienced $2.44 billion in net inflows for April, marking the strongest inflow month of 2026, as institutions accumulated spot while managing risk via short positions in futures, Andri Fauzan Adziima from Bitrue Research Institute explained to Decrypt. “This reflects a maturing market rather than fear-driven retail activity.”
Currently, shorts are paying approximately 12% annualized carry on their positions, despite the market not declining further.
Historical data across six similar negative funding periods since 2018 shows that each resulted in positive returns at 90 days, with a win rate ranging from 83% to 96%, compared to 55%-75% for random entries, Lund noted. The average maximum drawdown during these intervals dropped significantly from 16% to just 5%.
Analysts agree that a breakout above key resistance levels is the most probable catalyst for a short squeeze. “If shorts are forced to unwind and funding rates turn positive, Bitcoin could surge past $100K,” Matthew Pinnock, COO at Altura DeFi, told Decrypt. Conversely, if spot demand wanes before this occurs, prices may stabilize around $70K to $75K.
On the prediction market Myriad, owned by Decrypt’s parent company Dastan, participants remain optimistic, giving Bitcoin an 84% chance of breaking towards $84,000 next.
Lim identifies a critical threshold: “A clean break above $82K, backed by ETF flows, could trigger this shift,” he said. The question remains whether the squeeze signals a broader structural change or a tactical event within the existing institutional framework.
QCP Capital from Singapore echoes this sentiment, identifying $82,000 as a pivotal resistance level for Bitcoin’s recovery. This range also aligns with the 200-day exponential moving average, presenting a significant challenge to overcome.
The 66-day streak continues. “Bears were paying,” noted Glassnode analyst cryptovizarts in recent positioning data analysis from April. “Yet there was someone on the other side who wasn’t selling.”
