ASIC acknowledges TMX Group Limited’s (TMX) announcement that it has completed its acquisition of Cboe Australia.
TMX’s purchase of Cboe Australia was subject to ASIC’s regulatory approval under 852DG of the Corporations Act 2001 (Cth).
Formal lodgement, regulatory assessment and approvals of TMX’s application took place in July 2026.
TMX and Cboe, which will be rebranded as TMX Australia Exchange, will now work together on finalising the transaction elements and ensuring a smooth transition of ownership. ASIC will continue to provide regulatory oversight over the transition process, including timely consideration of any market operating rule changes that are required to ensure clarity for issuers and participants of the market during the transition.
ASIC is committed to facilitating competition in Australia’s financial markets. Greater competition provides more choice for investors and encourages greater foreign investment and international alignment.
Background
The acquisition follows TMX’s proposal to acquire Cboe Australia, following the entities’ previous announcement to enter a purchase agreement.
TMX is a global exchange group. It is Canada’s largest financial market infrastructure group and operates Canada’s core financial market infrastructure, including the Toronto Stock Exchange and TSX Venture Exchange for equities, Montréal Exchange for derivatives, and post‑trade services that provide central counterparty clearing, clearing, settlement, custody, and depository functions for Canadian securities markets.
Chi-X Australia was launched in Australia in 2011 as a competitor to the ASX, introducing an alternative trading venue for ASX-listed securities and contributing to increased competition and innovation in the Australian equities market. It was acquired by Cboe Global Markets in 2021, becoming Cboe Australia.
Cboe Australia currently has around 20% of Australia’s equity market turnover, representing approximately $2 billion of trades each day.
ASIC has worked closely with Cboe throughout the sale process to date to encourage an orderly transition to new ownership, including:
- In April 2026, ASIC acknowledged TMX Group entering into an agreement to purchase Cboe Australia and Cboe Canada.
- In November 2025, ASIC noted it would work closely with Cboe throughout the sale process (25-261MR).
Prior to the sale process, in October 2025, ASIC also approved Cboe Australia’s listing application (25-227MR).
