Abstract
I derive the incentive compatible and individually rational mechanism that maximizes the sum of the buyers’ ex-ante expected utilities. I also show that this mechanism minimizes the seller’s revenue. When payments are required to be non-negative, my mechanism takes the form of an arbitrarily weighted lottery with no participation fees, and the resulting allocation is generally not ex-post efficient. This means that before learning their valuations and if side payments from the seller to the buyers are not allowed, buyers as a group would be better off if they gave up ex-post efficiency in order to avoid positive payments. When transfers are allowed, the optimal mechanism is a standard auction with no reserve price and where the seller’s income is redistributed back to the buyers. This mechanism is robust to speculators if a buyer with value 0 never partakes in the redistribution.

Notes
Corchón and Serena (2018) provide a good summary of the recent contest theory literature.
Specifically, New Zealand Government’s Explorer Grants and Volkswagen’s Experiment! Grants.
I thank an anonymous reviewer for pointing out this particular point.
This is so because:
$$\begin{aligned} \textrm{E}_{\theta _i}\left[ \frac{1}{\lambda _i\left( \theta _i\right) }\right] =\int _{\varTheta _i}\left( 1-F_i\left( \theta _i\right) \right) d\theta _i=\overline{\theta }-\theta _iF\left( \theta _i\right) \Big |_0^{\overline{\theta }}+\int _{\varTheta _i}\theta _if_i\left( \theta _i\right) d\theta _i=\textrm{E}_{\theta _i}\left[ \theta _i\right] \end{aligned}$$
