CMC Invest vs CommSec 2026: Share Trading Platform Comparison
CMC Invest prices the first ASX stock or ETF buy under $1,000 at $0. CommSec Pocket charges $2 per trade up to $1,000, but caps the instrument set at 10 themed ETFs.
Mozo's 2026 head-to-head frames the pair as opposing endpoints on the Australian retail broking stack. CMC Invest operates as the disruptor: 16 markets, 40,000+ shares and ETFs, $0 brokerage on US, UK, Canada, and Japan equities. CommSec is the incumbent: Commonwealth Bank-backed infrastructure, 55%+ retail market share by accounts, approximately 3 million users, ~40,000 trades per day, ~$575 million combined daily volume.
Fee Architecture
CMC Invest: $0 on the first daily buy of an ASX-listed stock or ETF under $1,000; standard schedule applies beyond that threshold. Zero commission on entry trades across US, UK, Canada, and Japan venues.
CommSec Pocket: $2 flat per trade up to $1,000. The constraint is binding — 10 themed ETFs covering Australian shares, global shares, technology, and sustainability. Outside this list, the standard CommSec brokerage schedule applies. The 10-instrument ceiling is not a market; it's a curated subset.
Market Context and Capital Signals
ASX Australian Investor Study 2023: 7.7 million Australians hold on-exchange investments, the highest proportion in over a decade. ETF adoption sits at 20% and growing, per Mozo. CMC Invest has claimed four consecutive Mozo Experts Choice Awards, including Highly Commended for Online Share Trading 2025 and category wins in Regular Investor and Active Trader.
On the listed side, CMC Markets (LON:CMCX) closed Tuesday at £4.58, £6.50 Wednesday (+42%), £7.00 Thursday — a two-day move of 53%. Friday added another 2% to £7.14, clearing £2 billion market cap for the first time. FX News Group attributes the move to an upward revision of FY2027 revenue and EBITDA guidance alongside a multi-year front-of-shirt sponsorship deal with Everton FC. Comparables: IG Group market cap above £6 billion; Plus500 just above £3.5 billion.
Stability Assessment
Both platforms clear the smoke test. CommSec's bank-backed rails and bundled deposit-side infrastructure offset the restricted instrument list; CMC Invest's wider venue access and zero-commission entry trades compress cost for active retail flow. The binding variable is order routing — and on that metric, CMC's spec sheet runs longer. CommSec's edge lies in infrastructure inertia and account-side convenience. Choose by trade frequency and instrument breadth.
