Proof of Edge

Q started on the wrong side of Neymar’s World Cup. Fifteen days later it flipped, before the market did.

Q’s first look on April 3 was 13%, the wrong side. On April 18 Q flipped to 57% and published the call, while the market still said 43%.

At the April 18 signal price of 43¢, a $1,000 YES position would have settled at about $2,324 at resolution, before fees and slippage. The position first spent three weeks underwater, down as much as 20.9%. A fixed-duration exit would have lost.

What Q saw

The market was anchored on an early April disciplinary controversy. Ancelotti had publicly turned selection into a watchable test, two months to prove match fitness, and Neymar was passing it. He scored on April 14 and went the full 90 minutes days later. Q read a physical test being passed, priced like a coin flip weighted to failure. Q’s ceiling was 65%, and by June 16 the market at 84 was more confident than Q at 60. Q was right early and in print, never certain.

How Q tested it

Q tracked what would have broken the call. None of it triggered.
