Firstly, from the plot that you link (at least the one on the right) there actually seems to be a clear jump (total in 2017 is 300M from 150M the year before).
Secondly, I think the main reason is that Open Philanthropy didn’t just come into existence out of nothing, they started a partnership with GiveWell in 2014 (as the Wikipedia article says as well) and Good Ventures have already been giving through that, so it’s not that suddenly a new funder was there in 2017, it’s that a funder has been easing in over a long time and the founding of Open Philanthropy as an organisation was just one step in this process.

Cool, yep. This checks out.
Thanks!
