What is EA Global?

EA Global is the annual conference of the effective altruism community. This year there will be three conferences held in Boston, San Francisco, and London.

It is a gathering of people who have made helping others a core part of their lives. Speakers and participants discuss new thinking in the field of effective altruism, share new research, familiarize themselves with core concepts, and coordinate on global projects.

What is EA Global X?

In addition to the annual EA Global event organized by the Centre for Effective Altruism, we also support local groups to run their own conferences to promote and discuss effective altruism, through the EAGx series. See the EAGx page for more information.

What is effective altruism?

Effective altruism is about using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis. For more information about effective altruism, visit

How much does EA Global cost?

The standard registration cost for EA Global Boston is $384, and for EA Global San Francisco is $279, and the early bird price for London is £260. This is about half of our estimated cost per participant.

Extensive financial aid is available! We don't want cost to keep anyone away. This is true even if you are not low-income but, for example, are prioritizing donation. Please take financial aid rather than stay home!

Can I volunteer?

We have a few spaces left for volunteers at EA Global London. You can apply here.

What kind of food will be served?

Vegetarian and vegan food will be served at all three events.

Where will the events be held?

EA Global Boston will be at the Harvard University Science Center in Cambridge, MA.

EA Global San Francisco will be at the Palace of Fine Arts Exhibition Center in San Francisco, CA.
