No. TEDx does not allow speakers to pay or be charged in any manner, including production costs, recruiting sponsors, buying ticket blocks, or hiring coaches. Speakers give generously of their time, giving their ideas to the world for free. That is enough!
TEDx also does not pay speakers; however, many events offer benefits like covering travel costs and hotel accommodations where necessary, and access to exclusive networking events.
More information about speaking at a TEDx event can be found here.
