Options desks are loading up on high-strike BTC calls again—and the skew is flashing its loudest signal this month. Behind the scenes, institutional desks report aggressive demand for upside exposure despite recent sell-offs, hinting that pros expect an upside test into month-end while watching ETF flows and volatility compression as confirmation. Here’s what’s shifting under the hood—and how traders can position with defined risk.

What the options market is signaling

Recent flow shows a near-monthly-high positive call skew across major venues, a classic sign of demand for upside exposure. QCP Capital flags notable interest in high-strike August calls—including BTC 29 Aug 2025 calls around 118k/124k/126k—suggesting traders are paying up for convexity if momentum accelerates.

At the same time, Blofin notes long-dated sentiment has cooled toward neutral, with the 180-day skew approaching zero. Translation: near-term traders want upside, but the market isn’t betting on a runaway trend without validation from flows and macro.

Why this matters for traders

- Persistent call demand can pull spot higher via dealer hedging (gamma effects), especially into expiries and key levels. - ETF inflows can underpin spot bids, turning dips into entries; outflows can quickly unwind this. - Volatility is a swing factor: if IV compresses while price grinds up, outright long calls can suffer; if IV expands on a breakout, upside convexity pays.

Key validation signals to watch

• ETF net flows: sustained daily inflows support trend continuation; outflows argue for fade/hedge.
• Skew and IV: positive skew with rising IV favors debit spreads; rising skew with flat/down IV favors calendars/diagonals.
• Dealer positioning: watch open interest and large strikes (e.g., 118k–126k) for potential gamma “magnets” on fast moves.
• Macro prints: CPI, jobs, and Fed commentary can flip risk quickly—size accordingly.

Actionable setups with defined risk

• Bull call spread (near-dated): capture directional upside while offsetting IV risk; pick strikes around local resistance and a target zone.
• Diagonal call spread: buy near-dated call, sell farther OTM call in a later expiry to monetize skew while keeping upside.
• Spot + covered call: for dip buys on ETF inflow confirmation; sell OTM calls to harvest elevated skew.
• Put spread hedge: if chasing upside, cap downside with a debit put spread into macro events or if ETF flows wobble.

Risk factors to respect

- IV crush if price stalls: hurts outright long options—favor spreads to reduce vega exposure. - Flow reversals: ETF outflows and leverage flushes can erase gains quickly. - False breakouts: long-dated neutrality (180d skew ~0) implies hurdles to new ATHs without strong catalysts.

The bottom line

Near-term options are leaning bullish, but the market demands proof from ETF inflows and stable macro. Align entries with flow confirmation, prefer defined-risk structures over naked calls, and let spreads work with skew and volatility rather than against them.
