Apple Inc. (NASDAQ:AAPL) kicks off its Worldwide Developers Conference today at 1 p.m. ET, in what will be CEO Tim Cook’s final keynote before John Ternus takes over.

WWDC is Apple’s annual developer event, where the company unveils its new operating systems and software roadmap. Two years of broken Siri promises hang over today’s stage.

Kalshi has a market for what words will be spoken at the event.
