Not necessarily. They were unable to convince givewell they could make comparably effective use of additional money. They make have come out and explicitly said "we're fine for the next year", but I don't see givewell saying they did.
It sounds like they did:
Note that last year’s top-rated charity, VillageReach, does not have projected short-term funding needs (it expects to be able to meet these needs with funds not driven by GiveWell), as discussed previously.
It expects, not GiveWell expects. But hey, why argue about it? I've just asked.
As of today, GiveWell has two new top charities:
1. Against Malaria Foundation
2. Schistosomiastis Control Initiative
Their previous top charity, Village Reach, no longer has much room for more funding. Which is a good thing: partly through givewell's influence they now have as much money as they can put to good use.
