Rising funding rates and a massive options expiry point to growing bullish sentiment in derivatives markets
Bitcoin derivatives activity is intensifying as traders increasingly position for a potential year-end price move. Recent data shows a steady rise in perpetual futures open interest, accompanied by higher funding rates, suggesting renewed confidence among leveraged market participants despite near-term price resistance.
Perpetual futures open interest increased from 304,000 BTC to 310,000 BTC, coinciding with Bitcoin briefly testing the $90,000 level before pulling back. This rise in open interest reflects fresh capital entering derivatives markets, rather than position closures, highlighting growing speculative interest.
At the same time, the funding rate doubled from 0.04% to 0.09%, signaling that traders are increasingly willing to pay a premium to maintain long positions. This dynamic typically indicates bullish expectations, as perpetual contract prices trade above the spot market.
Elevated funding rates often point to strong directional conviction, but they can also introduce risk. When long positions become crowded, markets may be vulnerable to sharp pullbacks or liquidation-driven volatility if prices fail to move higher.
Bitcoin has so far struggled to hold above $90,000, retreating toward the $88,000 range, underscoring the tension between bullish positioning and spot market momentum.

Market uncertainty is further amplified by an upcoming end-of-year Bitcoin options expiry, with more than $23 billion in notional value set to expire. Call options are concentrated at $100,000 and $120,000, while put interest clusters near $85,000.
With a put-to-call ratio of 0.37 and max pain around $96,000, the data suggests traders are heavily skewed toward upside bets—bets that may face losses if prices fail to rally before expiry.
