The oil companies that won every auction went broke
In the 1960s, offshore drilling rights sold to the highest bidder — and the highest bidders kept losing money for decades before anyone figured out why.
For years, oil companies bidding on U.S. offshore drilling leases noticed something strange: whoever won the auction usually lost money on the deal. Not sometimes — reliably, year after year, across different fields and different decades. In 1971, three petroleum engineers at Atlantic Richfield finally wrote up the pattern and gave it a name that stuck: the winner's curse.
The mechanism is almost embarrassingly simple. Nobody knows exactly how much oil sits under a given patch of seabed, so every company sends in its own geologists to estimate. Some estimates run high, some run low, and the true value sits somewhere in the middle of all of them. But the auction doesn't award the lease to the company with the most accurate guess — it awards it to the company with the most optimistic one. Being right doesn't win you the auction. Being wrong in the generous direction does.
The fix, once someone named the problem, was almost as simple: bid less than your honest estimate, on purpose, and bid less aggressively the more competitors are in the room, since more bidders means a higher chance the top estimate is wildly inflated.
The same trap catches art buyers, corporate acquirers, and anyone bidding on a house in a market with twelve other offers. Winning isn't proof you valued it correctly. Sometimes it's the only proof you needed.
