TMX Group CFO Outlines Potential for Prediction Markets in Canada Tied to MEMX Developments

TMX Group, parent of the Toronto Stock Exchange, could introduce prediction markets in Canada if client demand develops. The exchange operator is monitoring US advancements, particularly those from Members Exchange (MEMX), as it deepens cross-border ties.

TMX Group Chief Financial Officer David Arnold said clients would ultimately determine the approach. “I think that is something that we could replicate in Canada,” he told Bloomberg. Arnold spoke at the Bloomberg Canadian Finance Conference in New York.

MEMX Deal Positions TMX for Event-Based Products

The comments align with TMX’s proposed combination with BOX Options Market, announced in July. The transaction would create a new US exchange group valued at roughly US$2.3 billion, with TMX owning about 59%. Completion is targeted for the second half of 2027, pending regulatory approval. As part of the deal, TMX plans to contribute approximately US$800 million in cash plus its existing stake in BOX. The resulting entity would operate three US-listed options exchanges, an equities exchange, and a market technology business.

MEMX filed in August for regulatory approval to offer binary contracts tied to corporate earnings measures. These yes-or-no products would settle on whether a company exceeds analysts’ earnings expectations. Arnold indicated such offerings could provide a model for TMX should demand emerge in Canada. As reported by Yogonet International, this would extend prediction-market products to established exchanges beyond traditional event-contract platforms. TMX’s majority position also grants closer exposure to US event-based trading trends.

Regulatory Patchwork Shapes Canadian Demand Outlook

Canadian access to prediction markets differs across provinces and product categories. Polymarket maintains limited availability in Ontario, Alberta, British Columbia, and Quebec. Ontario enforces a two-year ban after a settlement with the Ontario Securities Commission on short-term binary contracts. Kalshi operates via a partnership with Wealthsimple under the Canadian Investment Regulatory Organization, but its range is narrower than in the US, covering economic forecasts, environmental outcomes, and financial indicators while excluding short-term sports or political markets.

Arnold separately addressed potential extensions to trading hours, stating, “If there is enough demand, we will be very, very quick to follow suit,” though he questioned whether sufficient demand exists for some Canadian equities. Established operators continue exploring these products, as seen in Polymarket’s May partnership with Nasdaq Private Market for contracts on private company valuations, IPOs, and corporate events.

The core limitation remains unproven demand within Canada’s varied rules. Without clear client signals, TMX is unlikely to advance. Operators and investors must track how provincial frameworks respond to traditional exchanges entering this space, as regulatory alignment could accelerate product integration.
