SKN | Bitcoin Options Flip Bearish as Traders Rush to $85K Puts After 25% Price Slide

Key Points:
• Bitcoin’s options market has rotated sharply from bullish calls at $140,000 to downside protection centered on $85,000 puts.
• Open interest on the $85K strike now exceeds $2 billion, surpassing last year’s most popular upside bet.
• Analysts say bearish sentiment is peaking, but whale accumulation and oversold indicators suggest downside exhaustion may be approaching.

Bitcoin’s Derivatives Market Executes Full Sentiment Reversal

Bitcoin’s relentless drop from its October highs has triggered one of the fastest sentiment reversals in the options market in over a year. Once dominated by highly bullish positioning — with traders targeting $100,000, $120,000 and even $140,000 strikes — the market has now turned decisively defensive, mirroring bitcoin’s slide to around $91,000.

At the peak of bullish euphoria late last year, the $140,000 call option was the single most crowded trade on Deribit, with notional open interest consistently above $2 billion. Today, that same strike has fallen to $1.63 billion, overtaken by the $85,000 put, which now leads all contracts with $2.05 billion in open interest.

Options flow shows a dramatic shift: traders are loading up on downside insurance across the $80,000–$90,000 band, diverging sharply from the upside-heavy structure that dominated most of 2024 and early 2025.

Downside Protection Takes Center Stage

Deribit data shows open interest “stacking” at lower put strikes, a sign that traders fear further losses as bitcoin remains down more than 25% since Oct. 8. While call positions still outnumber puts in absolute terms, the pricing tells a different story: put premiums have jumped significantly, reflecting a strong skew toward downside hedging.

“Short-dated puts at $84K to $80K have seen the strongest volumes today,” said Deribit Chief Commercial Officer Jean-David Pequignot. “Front-end implied volatility is near 50%, and the curve shows a heavy put skew of 5–6.5% for downside protection.”

On decentralized options platform Derive.xyz, the 30-day skew has dropped to -5.3% from -2.9% just days ago, confirming an industry-wide rush for hedges. Dr. Sean Dawson, head of research at Derive.xyz, noted that December 26 expiries are seeing “large put concentrations” around the $80,000 strike.

The macro backdrop is also feeding caution. Weakening U.S. job market data and fading expectations for a December rate cut have depressed bullish conviction, while broader risk assets continue to exhibit elevated volatility.

Are Bears Overstaying the Trade?

Despite the increasingly defensive outlook, several indicators suggest the selloff may be nearing exhaustion. Bitcoin’s Relative Strength Index (RSI) is approaching 30 — a level traditionally associated with oversold conditions — while sentiment gauges have collapsed to rare extremes.

“With a Fear & Greed Index near 15 and RSI close to oversold territory, whale wallets holding more than 1,000 BTC have accumulated meaningfully over the past week,” Pequignot said, hinting that institutional players may be quietly positioning for a rebound.

Historically, periods of deep put-skew and extreme bearish sentiment have preceded notable reversals — not necessarily immediate trend shifts, but relief rallies that force hedged traders to unwind positions.

Still, with options markets pricing in elevated volatility and macro uncertainty clouding the remainder of the year, traders see little reason to aggressively re-risk until economic data stabilizes.

A Market Bracing for More Pain — But Primed for Reversal Risks

Bitcoin’s options landscape is now heavily tilted toward further downside, with $80,000–$85,000 emerging as the market’s new focal range. That may reinforce short-term bearish momentum, but such lopsided positioning also increases the likelihood of a sharp counter-move if selling pressure cools or macro data surprises positively.

For now, momentum remains tilted lower. Yet the combination of oversold conditions, whale accumulation, and historically extreme put positioning suggests that an abrupt shift — whether a relief bounce or a larger trend correction — could catch the market off guard.
