Welcome to spread betting at CMC Markets
Tax free profits
Profits made by a UK resident from spread betting are exempt from capital gains tax (CGT) and there is no stamp duty unlike traditional share dealing which can make it cost effective. Tax treatment depends on the individual circumstances.
Risk-free trading
Spread bet with CMC Markets and take advantage of risk-free trading for a week* on our special UK100 index. Buy and sell as many times as you want at £2 per point max and perfect your trading technique using our award wining platform Marketmaker
Tight spreads and low margins
Trade indices, currencies, shares and commodities with some of the tightest spreads in the market. Spread betting margins start from just 5% on UK shares. You can view spreads and margins on our full range of markets.
* CMC Markets will refund net losses (netting off the value of any opposing short or long positions) on our special UK100 instrument on each trading day. A week runs Monday to Friday for this promotion. To trade risk free for five full days you must start trading at the beginning of the week. Days cannot roll over to a following week.
