Over the five years through 2024-25, revenue is set to climb at a compound annual rate of 2% to £6.4 billion. This growth stems from recovering business confidence, which was previously shaken by Brexit, the COVID-19 pandemic and soaring inflation, deterring investments. Mounting demand for online and digital research services and intense political activity has also fuelled expansion. Facing stiff competition, market research and public opinion polling companies have innovated to gain a competitive edge, embracing acquisitions in order to gain access to new technology and niche markets, as well as heavily investing in technology to improve data collection and analysis. The shift towards digital advertising has driven the adoption of advanced data gathering and research methods to better understand online consumer behaviour, though there’s been a growing trend towards in-house research as an alternative. Revenue saw a 16.3% downturn in 2020-21, a reflection of the financial strain created by COVID-19 curtailing spending on research activities. The severity of this decline, however, was cushioned by increased market research investment from the public sector and private companies looking to navigate the aftermath of the pandemic. Revenue is forecast to grow by 2.7% in 2024-25, propelled by easing inflationary pressures and the collective effort of businesses to stabilise the economy and financial markets. Public-sector demand is also escalating, driven by the General Election and the continued political discourse necessitating insights into public opinion. Looking ahead, revenue is projected to rise at a compound annual rate of 3.1% over the five years through 2029-30, reaching £7.5 billion. Growth will be fuelled by a rebound in business confidence and an uptick in spending. Demand for companies specialising in web-based market research and social media marketing is expected to surge, supported by strong advertising activity and a mounting need for media research. As e-commerce continues on a steady growth path, there will likely be an increased emphasis on investing in novel research technologies and specialised data analytics capabilities.

Stock and commodity exchanges can benefit from various sources of revenue, ranging from fees charged through the purchasing and selling of stocks and commodities to the listing of companies on exchanges with IPOs. Yet, this hasn't meant exchanges have been free of challenges, with many companies looking to more attractive overseas markets in countries like the US that embrace stronger growth. The most notable culprits have been ARM and CRH, refusing to put up with the increasingly cheaper valuations offered by UK stock exchanges. Stock and commodity exchange revenue is expected to boom at a compound annual rate of 11.5% over the five years through 2024-25 to £15.4 billion. Boosted by the London Stock Exchange Group's Refinitiv purchase in 2021-22, the growth numbers seem inflated. The industry saw ample consolidations, aided by MiFID II's initiation in 2018. However, M&As have now decreased because of high borrowing costs. New reporting demands have bumped up regulatory costs, resulting in thinner profits. Banks, aligning with Basel IV, are pulling back on investments. Post-COVID market turbulence fuelled trades, but it's slowing down with economic stabilisation. The inflation slowdown pushes investors towards higher-value securities, boosting trade value despite lower volumes. The weak pound has been beneficial for revenue, especially for the LSEG, bolstered by dollar-earning companies in the FTSE 100. Stock and commodity exchange industry revenue is expected to show a moderate increase of 1.3% in 2024-25. Revenue is forecast to climb at a compound annual rate of 4.1% over the five years through 2029-30 to £18.8 billion. The cautious descent of interest rates from the Bank of England will slow down volatility and ensure greater business confidence in the UK. This will bring back up consolidation activity to support revenue growth, reviving the digital information and exchange markets. The most pressing concern for the industry will be potential limitations on access to the EEA for the clearing segment of the industry, which could shatter short-term growth and keep the tap running for companies exiting UK exchanges.

Social media platforms are integral to people's lives, offering ways to communicate, create and view content and share information. According to Ofcom, approximately 89% of UK internet users in 2023 used social media apps or sites. Teenagers and young adults are the biggest users, although there is rapid uptake among older age groups. Advertising is the primary revenue source for social media platforms, although subscription-based services are gaining momentum as platforms seek to diversify their incomes. TikTok is the success story of the last few years, becoming the most downloaded app between 2020 and 2022, according to Apptopia. The short-form video platform reported that it averaged revenue growth of over 450% between 2019 and 2022. After Musk's takeover, X, formerly known as Twitter, adjusted its content moderation and allowed previously banned accounts to return. As a result, over 600 advertisers have pulled their ads from the site because of fears their brand may be associated with malcontent. In response to falling ad revenue, X has introduced a subscription-based service which enables users to verify themselves and boosts the number of people who view their tweets. Meta-owned Facebook and Instagram have responded by introducing a similar service. Revenue is expected to grow by 14.3% in 2024-25, constrained by a slowdown in user growth for most major social media platforms. Over the five years through 2024-25, revenue is forecast to expand at a compound annual rate of 32.8% to reach £9.8 billion. Looking forward, regulations relating to how data is collected, stored, and shared will force advertisers and platforms to rethink how they can target their desired demographics. The rising prominence of AI will require the introduction of adequate regulations. The Online Safety Bill sets out new guidelines for social media platforms to abide by, with hefty fines in store for those who do not. Operating costs will swell as platforms look to meet consumers’ expectations, weighing on profit. Over the five years through 2029-30, social media platforms' revenue is projected to climb at an estimated 9.4% to reach £15.4 billion.
