Bitcoin Open Interest Surges to 2026 Record, Blowing Past Every 2025 ATH Session

TLDR:

• Bitcoin Open Interest has posted its largest increase of 2026, now exceeding levels recorded during the 2025 ATH formation.
• Binance leads derivatives market share at 34%, with a monthly average Open Interest of $2.5 billion recorded on May 5.
• Gate.io and Bybit follow with $1.75B and $1.15B respectively, showing broad capital return across major crypto exchanges.
• The $80,300 level remains a critical resistance zone, tied to the average cost basis of Bitcoin’s newest whale cohort.

Bitcoin Open Interest has recorded its largest increase of 2026, now exceeding levels seen during the 2025 all-time high formation.

This shift signals a gradual return of traders to derivatives markets after weeks of subdued activity. Funding rates have stayed broadly negative, yet the rise in Open Interest tells a different story.

Capital is slowly flowing back into futures, pointing to growing risk appetite among market participants.

Futures Market Drives Bitcoin’s Recent Bullish Momentum

The Bitcoin futures market is showing clear signs of renewed trader activity in 2026. Open Interest — a measure of total outstanding derivative contracts — has surged past its 2025 peak levels. This move is notable because it comes even as funding rates remain largely negative across major exchanges.

Binance continues to lead the pack in terms of market share in this segment. The exchange holds roughly 34% of total Open Interest, with its monthly average reaching $2.5 billion on May 5. Other platforms are also seeing notable capital flows alongside Binance.

Gate.io recorded approximately $1.75 billion in Open Interest during this period. Bybit followed with around $1.15 billion. Together, these figures show how broadly capital is returning across the derivatives landscape, not just on one platform.

This environment is a stark contrast to conditions earlier in 2026. Traders appear more willing to take on risk exposure through leveraged positions. However, leveraged markets can shift quickly, and any large liquidation event could amplify price swings significantly.

Key Resistance at $80,300 Remains Critical for Bitcoin Price

While futures activity climbs, Bitcoin’s spot price faces a key technical hurdle at the $80,300 level. According to market analyst Ali Charts, this price point represents the average cost basis of new whales — entities that purchased Bitcoin within the last 155 days.

When Bitcoin trades below $80,300, these newer large holders are sitting at a loss on their positions. Yesterday, Bitcoin briefly pushed to a high of $82,800 before retreating back below this threshold. That pullback brings renewed concern about selling pressure from these holders.

Ali Charts noted that whales holding at a loss are incentivized to exit positions near their break-even price. This behavior can trigger a chain reaction of selling that pushes prices further down. It is a pattern commonly seen during uncertain market phases.

On the other hand, a sustained move above $80,300 could change the dynamic entirely. Once these holders return to profit, the urge to sell diminishes. That shift in sentiment is typically what sets the foundation for a fresh upward trend in Bitcoin’s price.
