Key Points

  • Marex handled approximately 20% of contracts traded during the CME’s first weekend of 24/7 trading, concentrated in crypto-based derivatives.
  • The CME launched its continuous trading session over the weekend of May 30-31; Marex enabled several active clients on the opening day.
  • Marex plans to expand extended-hours availability to additional institutional clients in the coming weeks as round-the-clock trading grows at the CME and other exchanges.

Marex reported that it accounted for approximately 20% of the contracts traded on the CME during the exchange’s inaugural weekend of round-the-clock trading, the firm said on Tuesday. The continuous session ran over the weekend of May 30-31.

The company said it had enabled several active trading clients to participate on the opening day of 24/7 trading and that its flow represented about one-fifth of total contracts executed on the CME in crypto-based derivatives during that span.

Marex indicated it will broaden access to extended trading hours for additional clients over the coming weeks. The firm framed this rollout as part of a wider effort to supply institutional customers with new services as asset classes migrate toward around-the-clock trading at the CME and at other exchanges.

"We’re delighted to offer 24/7 trading services to our clients on the first weekend of trading. The direction of movement, especially for crypto markets requires agility and responsiveness. We are proud to be front-runners in the arena," said Gabe Scianella, Head of Clearing Risk, Americas for Marex.

The participation level reported by Marex was concentrated in crypto-linked derivative products during the weekend session. Beyond the initial group of active clients who traded on opening day, the company’s statement emphasized plans to make extended-hours connectivity available to a broader set of institutional users in the near term.

Market participants and infrastructure providers watching the adoption of continuous trading hours will observe how liquidity and client engagement develop as more market participants gain access. Marex positioned itself as an early provider of 24/7 services and highlighted the need for operational agility when trading hours extend beyond traditional sessions.


Context and takeaways

  • Marex reported handling about one-fifth of CME contracts traded in the first weekend of continuous trading, focused on crypto-based derivatives.
  • The CME’s continuous session spanned May 30-31, and Marex supported several active clients on the opening day.
  • Marex intends to expand extended-hours access to more institutional clients in the coming weeks as round-the-clock trading on the CME and other exchanges develops.

Risks

  • The pace and scope of Marex’s planned expansion of extended-hours access are subject to timing uncertainty - impacts trading services and client onboarding.
  • Crypto markets’ rapid directional moves, referenced by Marex, imply that volatility and the need for operational agility could challenge participants and infrastructure providers.
  • As asset classes shift toward round-the-clock trading at the CME and other exchanges, liquidity distribution and market structure adjustments remain uncertain for exchanges and institutional traders.
