Today’s selloff in MARA Holdings has sent shockwaves through the crypto mining sector, driven by a massive convertible note offering and aggressive hedging activity. With a 14.16% drop in under 4 hours, the stock’s collapse has ignited a frenzy in options markets and raised urgent questions about its near-term viability. The offering’s terms, coupled with looming conversion risks and hedging dynamics, paint a complex picture of market uncertainty.

Convertible Note Offering Sparks Hedging Chaos
MARA’s 14.16% intraday drop is directly tied to its $850 million convertible note offering, announced on Wednesday. The zero-coupon, 0.00% interest notes maturing in 2032 are convertible into cash, shares, or a mix, with the conversion price linked to the stock’s volume-weighted average price on the pricing date. The offering includes a $150 million over-allotment option, potentially raising $1 billion. However, the notes’ structure—lacking regular interest and featuring capped call transactions to mitigate dilution—has triggered hedging activity by counterparties. These hedgers are expected to purchase MARA shares or enter derivatives, creating a self-fulfilling downward spiral as buying pressure is offset by aggressive shorting in options. The $50 million earmarked for repurchasing existing 1.00% 2026 notes further signals financial strain, with the company’s 50,000 BTC treasury ($5.9B) offering little solace to equity holders.

Crypto Mining Sector Volatility Intensifies as MSTR Falters
The broader crypto mining sector is under pressure, with sector leader MicroStrategy (MSTR) down 3.59% intraday. MSTR’s recent struggles to defend its $230B market cap—backed by a 607,000 BTC treasury—highlight systemic risks in the sector. MARA’s 14.16% drop mirrors MSTR’s recent volatility, as both firms face scrutiny over capital allocation and Bitcoin’s role in corporate treasuries. While MARA’s $850M offering is unique in its zero-coupon structure, the sector-wide trend of leveraging Bitcoin holdings for financing has created a fragile ecosystem. MSTR’s decline underscores that even the largest players are vulnerable to market sentiment shifts, particularly when debt structures introduce conversion and dilution risks.

Bearish Put Pairs and Gamma-Driven Plays in a Volatile Market
• MACD: 1.125 (bullish divergence from 0.99 signal line)
• RSI: 72.09 (overbought territory)
• Bollinger Bands: 17.065 near lower band (14.04), signaling oversold
• 200D MA: 16.999 (current price at 17.065, marginally above)
• Key Resistance: 17.5–18.0 (200D and 30D support-turned-resistance)
• Key Support: 14.04 (lower Bollinger band)

MARA’s technicals present a paradox: a bullish MACD divergence and overbought RSI suggest short-term exhaustion, while the stock’s collapse into Bollinger lower bounds indicates panic-driven overselling. The 200D MA at 16.999 and 30D MA at 16.88 imply a potential rebound to 17.5–18.0, but the 14.04 support level is critical. Aggressive bears should prioritize high-gamma, high-liquidity puts, while cautious bulls may test 17.065 as a short-term floor.

Top Option 1: MARA20250801P17.5
• Strike: $17.50 | Type: Put | Expiration: 2025-08-01
• IV: 96.55% (high volatility)
• Leverage Ratio: 13.51%
• Delta: -0.514 (moderate sensitivity)
• Theta: -0.010766 (slow decay)
• Gamma: 0.145381 (high sensitivity to price swings)
• Turnover: $1.04M

This contract offers a 5% downside payoff of $0.435 (if MARA drops to $16.21), with high gamma ensuring sharp directional response. The 96.55% IV reflects market fear of a breakdown, making this ideal for a short-term bearish bet.

Top Option 2: MARA20250801P17
• Strike: $17.00 | Type: Put | Expiration: 2025-08-01
• IV: 94.82% (high volatility)
• Leverage Ratio: 17.51%
• Delta: -0.442 (moderate sensitivity)
• Theta: -0.015891 (moderate decay)
• Gamma: 0.146569 (high sensitivity)
• Turnover: $214K

This put offers a 5% downside payoff of $0.785 (if MARA hits $16.21), with a 94.82% IV and 17.51% leverage ratio amplifying returns. The 0.146569 gamma ensures it accelerates in value as the stock drops.

If MARA breaks below 14.04, MARA20250801P17.5 becomes a high-probability short-side play. Bulls should test 17.065 as a near-term floor but avoid overexposure until 17.5–18.0 resistance is cleared.

Act Now: Hedge Against MARA’s 14% Drop with Gamma-Driven Puts
MARA’s 14.16% selloff is a red flag for equity holders, driven by a zero-coupon convertible offering and aggressive hedging activity. The stock’s collapse into Bollinger lower bounds and overbought RSI suggest exhaustion, but the 200D MA at 16.999 and 30D MA at 16.88 imply a potential rebound to 17.5–18.0. Investors should prioritize MARA20250801P17.5 and MARA20250801P17 for bearish exposure, while monitoring the sector leader MSTR (-3.59%) for broader sentiment cues. Watch for a breakdown below 14.04 or a rebound above 17.5 to dictate next steps.
