Miami International Holdings (MIAX) Q2 2026 earnings review
Record Revenue and Margin Expansion Mask Emerging Market Share Cracks
MIAX delivered another quarter of accelerating financial metrics in Q2 2026, with Net Revenue climbing 35% YoY to a record $141.1 million and Adjusted EBITDA surging 57% to $76.8 million. Operating leverage is shining through, driving Adjusted EBITDA margin up 700 basis points to 54%. However, the pristine financial picture is clouded by a $30 million litigation settlement that severely compressed GAAP operating income growth to just 2%. Furthermore, while elevated macro volatility pushed options volumes up 25%, MIAX's actual market share slipped to 16.5%, cracking the company's long-standing narrative of continuous share capture.
🐂 Bull Case
The company's technology investments are paying off. An Adjusted EBITDA margin of 54% demonstrates MIAX's ability to efficiently scale its operations alongside industry volume growth.
Management lowered the top end of its FY26 adjusted operating expense guidance by $5 million. Following periods of heavy investment, cost controls are strengthening.
🐻 Bear Case
Options market share dropped to 16.5% from 16.7% YoY, and is down significantly from the 18.2% peak seen in 25Q4. MIAX is losing ground to competitors despite absolute volume growth.
The Futures business remains a structural drag, generating an Adjusted EBITDA loss of $9.5 million on just $5.1 million in revenue.
⚖️ Verdict: ⚪
Neutral. The sheer cash generation, margin expansion, and successful execution of M&A (TISE) make MIAX a financial powerhouse. However, the reversal in options market share and persistent cash burn in the Futures segment signal that competitive pressures are mounting. The $30M litigation charge further distracts from an otherwise excellent quarter.
Key Themes
Macro Volatility Powers Core Options Engine
Elevated market volatility acts as a direct macro tailwind for MIAX. Options average daily volume (ADV) jumped 25.3% YoY to 11.0 million contracts. This underlying demand drove a 34% YoY increase in Options net revenue to $124.4 million, confirming the core segment remains the primary growth engine.
Margin Expansion Through Operating Leverage
Adjusted EBITDA margin accelerated to 54% from 47% a year ago. The incremental revenue from non-transaction fees (higher member connections, new market data products, and the expiration of Sapphire fee waivers) is dropping straight to the bottom line, proving the scalability of MIAX's proprietary tech stack.
International M&A Proving Accretive
The International segment is establishing a stable, higher baseline following the June 2025 acquisition of The International Stock Exchange (TISE). Net revenue grew 151% YoY to $5.7 million, firmly cementing it as a reliable contributor to the top line and producing a positive $2.0 million in Adjusted EBITDA.
Options Market Share Narrative Busted
Throughout late 2025, management touted record market share gains, peaking at 18.2% in 25Q4. That trend is now reversing. Q2 2026 market share fell to 16.5%, below the 16.7% reported in the prior-year period. While total industry volumes pushed MIAX's absolute contract numbers higher, the company is fundamentally losing slice-of-pie to competitors, contradicting their core growth narrative.
Litigation Settlement Destroys Operating Profit Growth
A sudden $30 million litigation settlement charge (allocated heavily to the Options segment at $22.5M and Corporate at $7.5M) severely distorted GAAP metrics. Because of this, Operating Income grew a mere 2% to $27.8M despite the 35% surge in net revenues.
Futures Segment Remains a Profitability Sinkhole
The Futures business generated $5.1 million in net revenue (up only 2% YoY) while posting an operating loss of $12.7 million and an Adjusted EBITDA loss of $9.5 million. The highly anticipated launch of the Bloomberg index products (Tini B100 and B500) occurred this quarter, but the segment's financials show zero structural improvement. The aggressive investment spend here must eventually yield operating leverage.
Product Innovation: Launch of Tini Index Futures
During the quarter, MIAX successfully launched the Tini B100 Index Futures, Tini B500 Index Futures, and B500 Index Futures. These retail-sized contracts are designed to disrupt incumbent monopoly franchises by offering low fees. Execution here will be critical to fixing the broken profitability of the Futures segment.
Other KPIs
Accelerating significantly (+88% YoY) despite the $30M litigation hit. This was artificially bolstered by a massive $15.4 million income tax benefit, driven by a discrete tax benefit of $22.4 million related to share-based compensation.
Improving. Net revenue grew 27% to $5.5 million due to higher net transaction fees and improved pricing, narrowing the Adjusted EBITDA loss from $(0.9) million in the prior-year period. Management's focus on maximizing Equities revenue capture is working.
Guidance
Decelerating. Management lowered guidance from the previous $265 - $275 million range. This signals a shift from aggressive capacity building toward tighter cost discipline, which should further support EBITDA margins in H2 2026.
Accelerating. Raised from previous guidance of $27 - $30 million, increasing the gap between GAAP and non-GAAP earnings and acting as a stealth dilution mechanism for shareholders.
Accelerating slightly. Raised from previous guidance of $33 - $38 million, reflecting the heavy technology and infrastructure capitalization over the past 18 months, specifically in the Futures and Sapphire initiatives.
Key Questions
Options Market Share Erosion
Your options market share has slipped from a peak of 18.2% in Q4 2025 to 16.5% this quarter. Is this an intentional sacrifice of share for better revenue capture, or are you seeing intensified pricing competition from incumbent exchanges?
Early Traction on Tini Futures
With the Tini B100 and B500 index futures now live, what are the early adoption metrics among retail brokers? When do you project the Futures segment will reach breakeven Adjusted EBITDA?
Litigation Details and Finality
Regarding the $30 million litigation settlement, does this completely extinguish the outstanding Nasdaq matter, and are there any ongoing royalty or licensing obligations moving forward?
Pyth Token Strategy
You realized another mark-to-market unrealized loss on derivative and digital assets ($337K this quarter). What is the strategic rationale for continuing to hold the locked Pyth tokens on the balance sheet instead of divesting them?
