The Great Trading Boom: Why Brokers Must Act Now to Stay Relevant

Retail trading volumes surged in 2025—about $308 billion in US equities—driven by commission-free platforms, smartphone-native access, social media-driven information flows and AI trading agents, sustaining momentum into 2026. The piece argues this structural shift increases market liquidity and opportunity for brokers but raises retention and customer-acquisition cost risks: higher volumes only translate to durable revenue if brokers retain traders. It recommends brokers invest in real-time, AI-driven behavioural engagement (eg. inactivity triggers, personalised prompts) to convert episodic traders into long-term clients. Vendors like Solitics are highlighted as enabling rapid integration (up to 45 days) and improved retention, deposit volumes and engagement. The near-term market impact is greater retail participation and liquidity, while longer-term winners will be brokers that build real-time engagement infrastructure before volumes normalise.
