MEMX prediction contracts moved a step closer on Tuesday, August 11, when the exchange operator filed proposed rule change SR-MEMX-2026-25 with the SEC. Then the filing was announced the following day from New York. It would adopt a new Chapter 30 of the exchange rules. That chapter permits MEMX Options to list Equities Based Exchange Prediction Contracts.

The structure is straightforward. In practice, investors would trade complementary YES and NO contracts priced between $0.01 and $0.99. Each ties to objective, quantifiable measures of a company’s financial performance. Earnings, revenue, sales and other issuer-specific metrics all qualify. Subject to approval and operational readiness, MEMX targets an early 2027 launch. Interactive Brokers sits among the expected distribution partners.

MEMX Prediction Contracts Are Not the First Filing

One framing around MEMX prediction contracts needs correcting. This is not a challenger exchange getting ahead of larger rivals.

Cboe Global Markets unveiled a comparable plan roughly a month earlier. So MEMX is following rather than leading among established equities and options venues, and the first-mover prize the filing appears to chase has already been claimed. However, that does not make the filing unimportant. It changes what the SEC decision means. Because the agency now faces more than one proposal from registered exchanges, this is no longer a single test case.

Meanwhile, prediction markets have grown quickly through platforms operating under different regulatory regimes. Traditional venues have watched with a mix of alarm and opportunism. CME and other derivatives exchanges moved into event contracts rather than cede the category. MEMX prediction contracts extend that pattern into equities market infrastructure.

The MEMX Prediction Contracts Pitch Is Regulatory

Here the filing language makes the argument clear. MEMX is not primarily selling a new product. It is selling a supervised venue for one that already exists elsewhere.

Under the proposal, the contracts would trade on a registered national securities exchange. They would carry central clearing, know-your-customer requirements, and existing MEMX surveillance programmes. Each of those is a direct contrast with venues operating outside that framework.

Consequently, MEMX prediction contracts are positioned as the compliant version of a category regulators have found difficult. Whether the SEC accepts that framing is the open question. For years, the agency has worked through jurisdictional questions with the CFTC over event contracts. That boundary between a security-based instrument and a conventional event contract remains unsettled.

Notably, the metric choice reflects the same care. Contracts reference company financial measures rather than share price directly, which looks like a deliberate effort to stay clear of security-based swap territory.

Why MEMX Prediction Contracts Make Business Sense

Commercially, the MEMX prediction contracts logic is plain. The company built its reputation undercutting NYSE and Nasdaq on equities trading fees, a commoditised and thin-margin business.

Since then, diversification has followed. MEMX Options received SEC approval in 2022 and launched the following year. MX2 Options, a new pro-rata venue, goes live during 2026 and takes the operator to six markets. Event contracts would extend that push into a product class with better economics than cash equities.

Notably, the distribution question is partly answered already. Naming Interactive Brokers as an expected partner matters more than it might appear, because a new contract type without retail distribution reaches nobody.

What to Watch on MEMX Prediction Contracts

First, the comment period is the checkpoint. Filings of this kind get published for public comment. So objections from incumbent exchanges, investor advocacy groups or consumer protection organisations would preview how the wider fight unfolds.

Then watch how the SEC handles two filings together. With Cboe already in the queue, the agency can approve both, reject both, or treat them differently on their specifics. Divergent treatment would tell the market exactly where the line sits.

Finally, watch the 2027 timeline. MEMX prediction contracts carry a launch target that assumes approval, and slippage past early 2027 would signal the review is going harder than the filing anticipated. Approval would likely bring Nasdaq and NYSE filings quickly. Neither would leave a product category to competitors.
