Key moments

Jump directly to management's words in the synchronized transcript.

“We remain very excited about our Bloomberg Index Futures products and plan to launch B100 and B500 Futures in the second quarter of 2026. While we previously communicated a February launch date, we recently made the decision to reschedule it to ensure we have the same reliability and performance profile on our futures platform that we pioneered in options markets.” Thomas P. Gallagher, CEO
“In late '25, we announced the strategic sale of 90% of MIAX Derivatives Exchange or MIAXdx to Robinhood Markets in partnership with Susquehanna International Group while retaining a 10% equity stake. This transaction, which closed in January of 2026, provides MIAX with expedited access to the growing prediction markets through our retained equity position while also enabling us to maintain focus on our core product offerings.” Thomas P. Gallagher, CEO
