A wide-moat market utility at a pivotal moment: ASX’s monopoly-like cash equity infrastructure remains resilient, but the CHESS/ASIC reset must succeed to unlock rerating upside.
Overview
ASX Limited is Australia’s primary multi-asset exchange group and a cornerstone of national financial market infrastructure, providing an integrated chain from listings and trading to clearing and settlement across equities, derivatives, fixed income, and commodities. In 1H26 (to 31 Dec 2025), operating revenue rose 11.2% to $602.8m, driven by volatility-fueled strength in cash trading, clearing/settlement, and interest-rate futures, while Technology & Data also grew on rising market-data demand. Underlying NPAT increased only 3.9% to $263.6m as operating expenses surged 20% amid a comprehensive regulatory/technology reset. ASX’s moat is primarily structural—network effects, high switching costs, and near-natural-monopoly clearing/settlement—supported by the superannuation system’s steady capital inflows. However, the company is at an inflection point following the 2026 ASIC Inquiry, with a legally binding commitments roadmap, a $150m capital charge, a pivot in CHESS Replacement approach, and increased competition from TMX-backed Cboe, all elevating execution risk and keeping valuation below historic premiums.
