Over the five years through 2024-25, revenue has rocketed at a compound annual rate of 14.5% to £2.3 billion. The Online Stock Brokerages industry has gained users quickly, as many investors left their brokers and started trading online. The online space offered a quick and easy way for less knowledgeable people to start investing and experienced traders to get real-time updates. Recovered incomes, volatile stock markets, an increasing number of mobile connections and a growing appetite for online stock trading have fuelled revenue growth. The online stock brokerage industry experienced a rapid upward shift in revenue during the 2020-21 market volatility caused by the pandemic, rewarding commission-free platforms like Trading212. The sector managed to capitalise on surging and declining phases. Innovations became critical, with brokerages like Trading212, FreeTrade and eToro introducing attractive features to win over customers, like replicating other trade moves. Despite the sector's vulnerability during the sharp sink of Bitcoin in 2022, its subsequent rebound in 2024-25 brought renewed prospects. Offering stocks and shares ISAs and SIPPs helped certain brokerages attract more tax-savvy customers. Simultaneously, intense price competition saw various platforms reduce their commissions to lure new users, leading to a climb in revenue of 7.7% in 2024-25. Over the five years through 2029-30, revenue is set to push up at a compound annual rate of 7.9% to £3.3 billion. Investor uncertainty will weaken as macro-headwinds subside and stock markets worldwide stabilise. The value of UK and US stock markets is forecast to strengthen, enticing traders to online platforms. As UK business profits recover due to stability, businesses can manage costs efficiently, leading to increased returns and more trade commissions for online stock brokers. The brokerage industry faces fierce price competition, with companies reducing commissions to attract and retain users alongside developing novel product offerings, like AI insights and advice, ISAs, extended trading hour products and tight cybersecurity. The average profit margin is expected to improve as industry entrants, including eToro (UK) Ltd, become profitable after years of significant losses resulting from investing heavily in R&D and marketing to attract users.
