Five United States stock exchanges have confirmed plans to begin extended overnight trading sessions on December 6, 2026. This move follows industry discussions at a Security Traders Association conference regarding evolving market liquidity.
Why it matters
The expansion reflects an industry-wide effort to capture more volume outside of standard hours as firms leverage AI to better assess dark liquidity. This shift aims to utilize cheaper liquidity options while adapting to new regulatory approvals for tokenized stock trading.
Overnight trading currently accounts for 1% of total US equity volume, with average sessions valued at $4.5 billion. Five exchanges are set to expand these offerings under a 20% price boundary limit for overnight activity.
