Bitcoin Derivatives Surge as Traders Hedge with Puts

Bitcoin derivatives are expanding rapidly as the cryptocurrency trades around $84,000. Futures open interest is nearing $60 billion, and options open interest has risen above $50 billion. Although call contracts dominate the existing positions, recent trading volume shows a clear preference for puts, suggesting traders are seeking insurance against a price decline.

Futures Open Interest Rebounds

According to Coinglass data, total Bitcoin futures open interest has risen back toward $60 billion after spending June and July in the mid‑$40 billion range. The top venues by open interest are:

• Binance: $11.72 billion
• CME: $9.83 billion
• Bybit: $5.79 billion
• MEXC: $5.30 billion
• Gate: $5.21 billion
• Hyperliquid (decentralized perpetuals): $3.53 billion
• OKX: $3.27 billion

These eleven platforms together account for more than $49 billion of open BTC futures positions. Leverage usage is being trimmed on several exchanges, with Binance, MEXC, Hyperliquid and Bitunix reporting declines in open interest over the past 24 hours.

Options Open Interest Tops $50 Billion

Bitcoin options open interest has surged above $50 billion, the highest level observed since late 2025. Calls represent roughly 60 % of the total open interest, amounting to about 363,000 BTC, while puts account for about 242,000 BTC.

In contrast, fresh options trading volume is put‑heavy: puts made up 58.2 % of 24‑hour volume (≈40,200 BTC) versus calls at 28,900 BTC. This divergence indicates that traders are building bullish exposure while simultaneously purchasing downside protection.

Key Contracts

• Oct 30 $95,000 call – 23,275 BTC open interest
• Oct 30 $90,000 call – 15,590 BTC open interest
• Oct 30 $100,000 call – 12,850 BTC open interest
• Thursday $80,000 put – highest 24‑hour volume

Funding Rates and Liquidations

Annualized funding rates across major venues remain positive, generally between 1 % and 4 %, with Deribit posting occasional spikes above 5 %. Longs are paying funding to shorts, reflecting a still‑upward bias.

Recent liquidation data show short positions taking the brunt of market moves: over $250 million of short contracts were liquidated on September 21, and another $130 million on September 18. Earlier in the month, long positions faced $150 million in liquidations on September 3.

Max‑Pain Levels and Upcoming Expirations

Max‑pain calculations—prices where the greatest amount of expiring options would expire worthless—cluster around $76,000 for the September 25 expiry on Deribit and OKX, while Binance’s max‑pain sits near $80,000. Bitcoin’s spot price of $84,416 sits above these levels, creating a gap that could influence price action as contracts expire.

Further out, max‑pain estimates range from $86,000 for September 26 down to $60,000 by mid‑2027 across various platforms.

Outlook

The derivative market shows a split personality: a bullish open‑interest profile dominated by calls, paired with active put buying for protection. With roughly $16 billion of options set to expire on September 25, the outcome of that expiry could shape short‑term price dynamics.
