Sourcing and executing very large equity orders can be challenging in fragmented markets, particularly when concerns over information leakage discourage traders from exposing their intentions, according to Chris Jackson, Global Head of Equities at Liquidnet.

“Sourcing and executing very large orders can be difficult in fragmented global equity markets. The fear of information leakage for these highly sensitive orders can also discourage participation in large block trades through a lack of trust,” Jackson told Traders Magazine.

On Tuesday, October 6, Liquidnet announced the launch of SuperBlock Targeted Invitations (TI), a liquidity discovery solution designed to help traders find natural block liquidity by improving interactions between buyers and sellers.

SuperBlock TI builds on Liquidnet’s existing Targeted Invitations capability, which allows buy-side traders to notify potential counterparties of their intent to trade. According to Liquidnet, the new offering extends that approach to SuperBlocks, allowing traders to share trading interest in exceptionally large orders with a broader audience while maintaining control over its distribution.

Under SuperBlock TI, senders can choose who receives an indication of interest, what information it contains and when it is distributed, Jackson said. “SuperBlock TI addresses these challenges by putting the buy-side in full control of how trading interest is distributed. Senders can choose who receives their indications of interest, the information it conveys and when it is sent.”

Jackson said the solution expands liquidity discovery by allowing traders to share an IOI with a broader group of relevant counterparties, while retaining control over who receives the trading interest and what information is disclosed. “This takes place within Liquidnet’s trusted, unconflicted agency environment, helping participants access liquidity while limiting information leakage and market impact,” he said.

Every SuperBlock TI must also be backed by a live, tradeable client order, according to Jackson, who said the requirement is intended to reassure recipients that an invitation represents genuine trading interest and an actionable opportunity. “To be successful, SuperBlock TI needs the trust of traders by ensuring that indications of interest are backed by genuine intent. This is why every SuperBlock TI is backed by a live tradeable client order.”

According to Jackson, linking each invitation to an active order is intended to give recipients greater confidence when deciding whether to engage. “This gives recipients reassurance that each SuperBlock TI represents an actionable trading opportunity from an active order. Credibility is crucial: our ambition is to issue the highest quality IOIs in the industry.”

The launch follows Liquidnet’s introduction of the broader SuperBlock initiative in 2024. Jackson said more than 1,500 SuperBlocks were traded globally between its launch and May 2026. “We have learned that there is significant demand for very large block orders,” he said. “The discretion, market impact savings and trade cost savings are significant benefits to our clients.”

Liquidnet separately reported that from January 2025 through June 2026, SuperBlock delivered total savings of 64.5 basis points, or $55 million, to its buy-side members. The firm defines total savings as spread savings plus market impact savings.

The firm also said its global network includes more than 1,100 members and more than $110 billion of global resting daily liquidity in the Liquidnet pool. SuperBlock TI is designed to help participants access more of that liquidity by connecting buyers and sellers of large orders, according to Liquidnet.

Buy-side traders were also involved in developing the new functionality. Jackson said SuperBlock TI was created in collaboration with Liquidnet’s SuperBlock Advisory Group, which is made up of senior buy-side members across EMEA, the Americas and APAC.

“By working closely with them, we built a solution designed around their needs and the way they trade, helping them address some of their most complex trading challenges,” he said.

According to Jackson, SuperBlock TI is part of a broader shift in how Liquidnet serves clients in global equities. He said the business is being built around three main workflows: block trading; algorithmic trading through Meridian, its upgraded offering for algorithmic workflows; and the Liquidity Desk, where coverage specialists help clients use the Liquidnet pool for complex orders.

Jackson said block trading remains an important part of that strategy, with SuperBlock TI intended to help clients find additional natural liquidity while maintaining discretion. “What comes next is our drive for growth in each of these areas as we build new solutions to help clients leverage our network, unlock more liquidity and execute their most complex orders,” he said.
