By 2026, best prediction market sites will allow traders to exploit pricing discrepancies between competing venues. Other things being equal, two sites may offer differing probabilities for the same instrument. In such a case, a trader can take positions on both ends of the instrument and capture a profit regardless of the outcome, as long as the total purchase costs are less than 100 cents and the costs are incurred prior to the venue making an adjustment to the instrument’s odds.
There are three venues available for examination. Polymarket, Kalshi, and Manifold collectively processes in excess of $12 million in daily volume.
