Bitcoin surged Thursday as a short squeeze took hold of the derivatives market, with open interest in Bitcoin futures approaching $25 billion for the first time since late 2025. The leading cryptocurrency climbed 7.2% to $68,450, erasing losses from the prior session and marking its largest single-day gain in three weeks.

Market Context

Broader risk asset sentiment turned positive as Federal Reserve officials signaled a more dovish stance on monetary policy ahead of next week's FOMC meeting. The S&P 500 gained 1.1% while the tech-heavy Nasdaq rose 1.4%, creating a favorable environment for digital assets. Ethereum rose 5.8% to $3,420, mirroring Bitcoin's momentum but trailing the leading cryptocurrency's percentage gain.

Analysis

The short squeeze was driven by a rapid unwinding of bearish positions as Bitcoin breached key resistance at $66,000. On-chain data from Glassnode indicated that short-term holders who had accumulated positions below $65,000 began taking profits, while institutional buyers added to spot exposure through purpose-built vehicles. The funding rate on major exchanges flipped positive for the first time in 12 days, signaling that market participants were willing to pay a premium for long exposure.

Retail traders on platforms including Robinhood and Coinbase reported elevated buying activity, though institutional flow data from Bloomberg suggested that over 60% of Thursday's price appreciation came from aggregated over-the-counter desk activity. The rapid compression of short positions triggered a cascade of stop-loss orders, amplifying the move higher.

Key Numbers

- Bitcoin price: $68,450, up 7.2% ($4,590)

- Bitcoin futures open interest: $24.8 billion, approaching record high

- 24-hour trading volume: $89.2 billion across major spot and derivatives exchanges

- Ethereum price: $3,420, up 5.8%

- Long-to-short ratio on Binance: 1.42, up from 1.18 Wednesday

What to Watch

Next week's FOMC meeting represents the primary catalyst for near-term volatility. Markets are pricing in an 82% probability of a 25 basis point rate cut, according to CME Group data. A more hawkish-than-expected outcome could reverse Thursday's gains and trigger a new wave of short positioning. Key resistance sits at $70,000, while support has shifted to $66,000 following the breakout. Bitcoin ETF flows will also be monitored closely after three consecutive days of net outflows totaling $412 million.

The derivatives market's elevated open interest suggests heightened leverage on both sides, increasing the potential for sharp reversals if sentiment shifts. Traders should monitor funding rates and exchange whale activity for early warning signs.
