- Robinhood and Susquehanna will acquire 90% of MIAXdx, gaining regulatory infrastructure that enables listing and clearing of scalable, compliant event-based derivatives in the U.S.
- The partnership combines Robinhood’s retail distribution with Susquehanna’s market-making depth, creating a structure where prediction markets can function with reliable liquidity and standardized contracts.
- The exchange plans to launch in 2026, positioning prediction markets for mainstream adoption as regulated financial products rather than experimental or limited-access trading instruments.
Robinhood and Susquehanna are acquiring MIAXdx to build a regulated exchange for event-based derivatives, signaling a major shift in prediction markets and retail finance.
A SHIFT YEARS IN THE MAKING
When Robinhood and Susquehanna International Group announced plans to acquire a majority stake in MIAXdx — formerly LedgerX — the news didn’t immediately spark headlines. Yet beneath the surface, this move represents a structural shift: the convergence of retail brokerage access, institutional liquidity, and fully regulated derivatives infrastructure.
LedgerX had once been associated with the now-bankrupt FTX empire. After the collapse, Miami International Holdings acquired the exchange in 2023, giving it a new identity and regulatory lifeline under the MIAX umbrella. MIAXdx retained a valuable advantage: approval from the Commodity Futures Trading Commission as a Designated Contract Market and Derivatives Clearing Organization.
Now, another transformation is underway. MIAX will retain about 10% of the business, while the remaining 90% will transfer to a group led by Robinhood. Financial terms haven’t been disclosed, but the ambition is clear: this isn’t just an acquisition. It is an attempt to control the full lifecycle of listing, clearing, and trading event-based derivatives.
WHY THIS DEAL MATTERS
While Robinhood and Susquehanna already have exposure to prediction markets, they have always operated through third-party platforms. Robinhood offers event contracts to retail users through Kalshi, and Susquehanna serves as a market-maker there. But relying on external exchanges comes with limitations — particularly around listing flexibility, settlement rules, and contract expansion.
This acquisition removes those constraints. Instead of participating in someone else’s marketplace, the two companies will own the infrastructure. Robinhood will serve as the controlling partner, while Susquehanna will act as the initial liquidity provider, ensuring that once the exchange goes live, traders will have active counterparties from day one.
The pairing of a retail-focused trading platform with a major institutional liquidity engine is rare — and intentional. It positions both companies to shape the next phase of regulated prediction-based products.
REGULATION AS A COMPETITIVE ADVANTAGE
Prediction markets have always attracted interest, especially from users looking to trade outcomes rather than traditional assets. However, regulatory uncertainty in the United States has slowed widespread adoption.
MIAXdx changes the equation. With its CFTC-regulated market and clearing approvals, the exchange offers a pathway to scaling event contracts under a framework traditionally reserved for futures and options. Rather than operating under narrow exemptions or limited contract caps, the new partnership has the regulatory positioning to expand into larger, standardized products designed for both retail and professional users.
This gives prediction markets something they have historically lacked: regulatory stability at industrial scale.
THE STRATEGIC PLAY BEHIND 2026
The new exchange is expected to begin operations in 2026, and the timing is deliberate. Prediction markets tend to attract attention during periods of heightened political or economic uncertainty. Beyond election-driven interest, traders increasingly use event-based products to express views on economic releases, policy outcomes, commodity disruptions, and macro-level forecasts.
Retail investors want new instruments beyond equities and crypto, while institutions are seeking ways to model probability more directly. Robinhood brings distribution. Susquehanna brings liquidity. MIAXdx brings regulatory legitimacy.
Together, they form a structure capable of scaling these products far beyond niche experimentation.
A NEW PHASE FOR MARKET DESIGN
Financial markets have expanded steadily toward alternative assets, fractional access, and more flexible contract structures. Prediction markets push that progression one step further: trading the probability of real-world outcomes.
Rather than simply speculating on price movement, traders gain the ability to price information itself. If successful, this model could evolve into something closer to a real-time forecasting layer for finance, policy, and even public decision-making.
The acquisition positions MIAXdx not just as a rebranded LedgerX, but as a potential foundational layer for this emerging category of event-based financial infrastructure.
WHERE THIS GOES NEXT
There are still open questions:
Will the marketplace remain focused solely on event-driven contracts, or expand into crypto-adjacent derivatives?
Will regulators impose new limits, or normalize these products as they did with options decades ago?
And will retail investors treat event markets as a tool for speculation, hedging, or something new entirely?
None of those answers are clear yet. What is clear is that prediction markets are no longer operating at the fringe of finance. With this acquisition, they are moving into the regulated mainstream — with retail access, institutional liquidity, and clearing infrastructure aligned under one ecosystem.
This marks the beginning of their institutional era.
