Canadian exchange operator TMX Group has agreed to acquire Cboe Australia and Cboe Canada from Cboe Global Markets for $409 million AUD, marking a significant cross-border push into Australia’s capital markets. The deal brings together two mid-tier exchange platforms that generated roughly $89 million AUD in revenue in 2025 and positions TMX as a direct challenger to ASX Limited.
At its core, TMX runs stock exchanges, the infrastructure that allows companies to list their shares and investors to trade them. Its flagship is the Toronto Stock Exchange, Canada’s equivalent of the ASX. Cboe operates similar platforms globally, but with a stronger focus on derivatives and trading technology. In Australia, Cboe already acts as a smaller rival to the ASX, handling around 20% of equity trading. TMX is effectively buying a competing version of the ASX, including the technology, licences, and market relationships needed to run an exchange, giving it an immediate foothold in Australia.
The strategic rationale is clear. Australia and Canada share structurally similar markets: both are resource-heavy economies with strong mining and energy pipelines, and both rely heavily on equity markets to fund growth. By combining these platforms, TMX is building a cross-border listings and trading ecosystem, particularly attractive for resource companies seeking dual listings or deeper pools of capital.
For Cboe, the sale reflects a broader strategic shift. The firm is exiting smaller equities markets to focus on higher-growth areas like derivatives, data, and digital assets. For Australia, the timing is critical. Cboe Australia only recently received regulatory approval to list companies, opening the door to long-awaited competition in IPOs, an area historically dominated by the ASX. Backed by TMX, that competition could now become far more credible.
The deal remains subject to regulatory approvals, with the Australian Securities and Investments Commission (ASIC) expected to fast-track its assessment given Cboe’s role in maintaining competition in local markets.
The implications are meaningful: more competition could drive lower fees, better technology, and greater choice for issuers and investors. More broadly, TMX’s entry signals growing global interest in Australia’s capital markets, particularly as demand rises for commodities critical to the energy transition.
