TMX Group to Acquire Cboe Canada and Australia in US$300M Deal

TMX Group Limited will pay US$300 million (C$409 million) to acquire Cboe Global Markets' Canadian and Australian exchange businesses, a cross-border consolidation that removes one of the last independent competitors to the Toronto Stock Exchange and positions the Canadian operator as a dominant force in global mining and energy-transition listings.

The deal, announced April 22, 2026, folds Cboe Canada (the former NEO Exchange and MATCHNow dark pool) and Cboe Australia (previously Chi-X Australia) into TMX's portfolio, which already includes the TSX, TSX Venture Exchange, and the Montreal Exchange. The combined Cboe businesses generated roughly C$87 million in revenue and C$25 million in adjusted EBITDA in 2025. Management expects the transaction to be accretive to adjusted earnings per share within 12 months of closing, before synergies.

What does this mean for Canadian market participants?

For brokers, issuers, and institutional investors operating in Canada, the acquisition collapses a fragmented equities landscape back toward a single operator. Cboe Canada ran four trading venues: MATCHNow, NEO-L, NEO-N, and NEO-D, alongside listings for ETFs, Canadian Depositary Receipts, and corporate issuers. Under TMX, those venues will sit alongside the TSX and TSX Venture order books, which together already handle the overwhelming majority of Canadian equity volume.

TMX argues the consolidation will cut direct and indirect costs for participants by reducing the complexity of routing orders across multiple marketplaces and shrinking the connectivity, data, and clearing overhead that firms carry to access each venue. The company also points to improved execution quality and resiliency as benefits, though those claims will face scrutiny from the Canadian Investment Regulatory Organization and the Ontario Securities Commission during the approval process.

The competitive implication is less comfortable. Cboe Canada was the only meaningful challenger to TMX's domestic listings franchise after the NEO Exchange merger in 2022. Its removal leaves Canada with no significant alternative senior listings venue, a structural shift that regulators will weigh against the efficiency gains TMX is promising.

Why does Australia matter to TMX?

The Australian leg of the deal is the more strategically ambitious piece. Cboe Australia operates an equities trading venue that competes with the Australian Securities Exchange and recently secured a corporate listings license, opening the door to challenge ASX's near-monopoly on primary listings in a market dominated by resources companies.

That resource concentration is the strategic prize. Australia and Canada are the world's two largest centres for mining finance, and the TSX and TSX Venture already list more mining companies than any other exchange globally, hosting roughly 40% of the world's public mining companies by count. Combining that franchise with an Australian listings venue creates a single operator with meaningful footholds in both ends of the global critical-minerals pipeline, at a moment when Western governments are pushing to reshore supply chains for lithium, copper, nickel, and rare earths away from Chinese control.

The energy transition angle sharpens the thesis. Demand for mining capital tied to battery metals and grid infrastructure has grown sharply, and issuers increasingly seek dual-listing structures to tap both North American and Asia-Pacific investor pools. A unified TMX-Cboe Australia platform gives TMX a credible pitch for that dual-listing flow.

How does this fit TMX's growth strategy?

The acquisition extends a multi-year expansion that has pushed TMX well beyond its traditional Canadian exchange roots. The 2023 acquisition of VettaFi, the index and ETF data provider, for roughly US$848 million was the company's largest international bet to date. The Cboe deal is smaller in absolute terms but more directly aligned with TMX's core marketplace business.

Chief Executive John McKenzie said the transaction represents a chance to "strengthen our domestic marketplace for clients and the entire stakeholder ecosystem" while expanding into a region TMX "knows well." Cboe Global Markets CEO Craig Donohue framed the sale as positioning the two businesses "for their next chapter," a signal that Cboe is redirecting capital toward its core U.S. options and derivatives franchise rather than defending sub-scale international equities operations.

TMX expects revenue growth from the combined businesses to track its long-term financial objectives. Canaccord Genuity and Macquarie Capital are advising TMX on the transaction. Closing for the two businesses will happen separately, each contingent on regulatory sign-off in the respective jurisdiction.

What are the risks to the deal closing?

Regulatory approval is the clearest hurdle. In Canada, competition authorities and provincial securities regulators will examine whether removing Cboe Canada from the market harms price discovery or raises trading costs. The Competition Bureau cleared TMX's 2022 acquisition of Aequitas NEO with conditions, and a similar behavioural remedy package is plausible here.

In Australia, the Australian Competition and Consumer Commission and ASIC will assess the impact on competition with ASX, which itself has faced regulatory criticism over its clearing monopoly. Paradoxically, introducing TMX as a new challenger to ASX may strengthen rather than weaken the competition case on that side of the Pacific.

Why This Matters to FinanceX Readers

The TMX-Cboe deal is a test case for how capital markets infrastructure is consolidating around specialisation. Cboe is retreating from sub-scale international equities to double down on derivatives; TMX is buying scale in the sectors where it already leads.

For investors in listed exchange operators, the transaction reinforces a broader pattern: exchanges are increasingly competing on vertical depth within specific asset classes rather than geographic breadth.

For issuers and institutional participants, the immediate question is whether consolidation delivers the promised cost reductions, or whether reduced competition translates into higher fees once integration is complete.
