The Globe and Mail reports in its Thursday edition that TMX Group, parent of the Toronto Stock Exchange and the TSX Venture Exchange, said Wednesday it will pay $300-million (U.S.) for the Canadian and Australian assets of Cboe Global Markets. The Globe's Jameson Berkow writes that the purchase price for both operations is less than the $350-million (U.S.) that Chicago-based Cboe paid for two acquisitions -- MATCHNow in 2020 and the NEO Exchange in 2021 -- to establish its Canadian trading business. The deal would allow TMX to consolidate its already dominant position in Canadian capital markets, raising questions about the state of competition in the sector. While Cboe Canada has lost part of the 16-per-cent domestic market share it held when the NEO deal closed in early 2022, its platforms still handled 12.5 per cent of Canadian equity trading volumes during the first three months of 2026. "This would be a step in the wrong direction," Som Seif, who runs Purpose Investments Inc., said in a LinkedIn post. "Every country that has ceded monopoly control of market infrastructure has paid a price in innovation, cost and ambition." Purpose offers multiple exchange-traded funds that trade on both the TSX and Cboe Canada.
