The ? Word event organizer announced Monday that Tesla and Spacex CEO Elon Musk will be a featured speaker, along with Square and Twitter CEO Jack Dorsey and Ark Investment Management (Ark Invest) CEO Cathie Wood.

The event is scheduled to start at 12 p.m. EDT on Wednesday, July 21. It will feature a live discussion with Musk, Dorsey, and Wood.

Musk and Dorsey initially agreed to have a discussion about Bitcoin at The ? Word event in June. Dorsey tweeted to Musk at the time: "Let's you and I have a conversation at the event. You can share all your curiosities."

According to the event website, "The ? Word is a Bitcoin-focused initiative that aims to demystify and destigmatize mainstream narratives about Bitcoin, explain how institutions can embrace it, and raise awareness around areas of the network that need support."

The event is hosted by the Crypto Council for Innovation (CCI), a global alliance of crypto industry leaders.
