Liquidnet has introduced SuperBlock Targeted Invitations, a new feature allowing traders to share large order interests with specific counterparties. The tool is designed to help institutional investors find liquidity for large trades while limiting the risk of information leakage.
Why it matters
By connecting traders with natural block liquidity in a controlled environment, this feature aims to minimize the market impact often associated with large buy-side transactions. This helps firms optimize their execution quality and manage costs more effectively during high-volume trading periods.
The SuperBlock initiative delivered $55 million in total savings to buy-side members from January 2025 through June 2026, representing 64.5 basis points of savings. These gains were realized across more than 1,500 large trades conducted globally.
The players
Liquidnet
A global institutional trading network providing liquidity and execution services to over 1,100 buy-side members.
SuperBlock Advisory Group
A coalition of senior buy-side members from EMEA, the Americas, and APAC that collaborates on trading solution development.
The details
The platform functions by requiring each invitation to be backed by a live, tradeable client order to ensure authenticity. Users maintain control by selecting their own recipients and determining the timing of information distribution, a process refined through collaboration with a senior buy-side advisory group. This controlled transparency helps traders avoid revealing their full hand to the broader market, which can otherwise trigger unfavorable price swings.
Timeline
2024: Liquidnet introduced the broader SuperBlock initiative.
January 2025 - June 2026: SuperBlock delivered $55 million in total savings.
May 2026: Over 1,500 SuperBlocks were traded globally.

Money Landscape
This development marks an expansion of the SuperBlock trading framework introduced by Liquidnet in 2024. It follows a growing industry shift toward minimizing market impact by fragmenting large orders into smaller, private, and highly targeted segments.
Institutional investors and asset managers should review their current execution workflows to determine if targeted invitations can reduce the market impact on their portfolio rebalancing. Traders should discuss with their internal teams how this tool integrates with existing algorithmic and liquidity desk strategies.
The takeaway
The addition of targeted invitations represents a broader effort to reduce transaction costs in the institutional equity market. Traders should track the performance of their block trades against previous benchmarks to assess if these new tools yield tangible cost improvements for their funds.
