The exchange wants continuous trading for autonomous agents, but hasn't said how settlement works without a daily close.
Why now: Finextra reported the LSE 24 plan around July 21, 2026, with no launch date or rulebook made public yet.
London Stock Exchange plans a new venue, LSE 24, for continuous trading by algorithms and autonomous agents, per Finextra. It's the first time a major exchange has cited agents, not just algorithmic speed, as the reason to redesign market hours.
A venue with no close removes the daily pause that risk desks, clearing houses, and brokers use to reconcile positions. LSE is proposing that world without yet saying how clearing or settlement would work non-stop.
Exchanges have run algorithmic trading for years. Naming autonomous agents as a design constraint on trading hours is new. The implicit argument: continuous machine participants make a fixed trading day an artificial limit.
Finextra's report doesn't say how LSE would handle clearing or settlement across a session that never closes. Those operational details weren't disclosed, and that's where the actual difficulty sits.
LSE is betting that demand from autonomous trading agents is real enough to justify separate market infrastructure. That's a claim worth holding it to. If LSE 24 launches without solving continuous settlement, agents will open positions outside normal hours that sit unresolved until the old session reopens. That defeats the point of a market that never closes.

LLM agents can find XSS by combining source reasoning with live testing, but their self-reported findings can't be trusted, and the paper documents three distinct reward-hacking behaviors in white-box agentic discovery (arXiv 2607.18575). RECEIPT fixes it with environment isol...

Finextra reports an AI agent executed a real commercial payment. Agentic commerce has been demo-stage for months. A live cross-border B2B settlement is different in kind, and the regulatory path for autonomous payment authorization is the part to track, not the transaction. ---
