What is the Capper Tracker?
The Capper Tracker is a public leaderboard of sports-betting cappers on X. Their public picks are collected, graded automatically against official game data, and ranked by verified units profit and loss. Nothing is self-reported and records cannot be edited or deleted.
What are the biggest active markets?
The markets the tracked cappers currently have the most money on, ranked by units staked and limited to games that have not finished. The percentage beside each side is the share of that tracked stake, not a probability that the side wins.
How are the winnings on this board taxed?
Gambling winnings are taxable income, and they do not net against losses. Losses come back only as an itemized deduction, capped at total winnings and, from 2026, limited to 90% of the losses. So a bettor who won and lost the same amount can still owe tax, because a tenth of the losses is no longer deductible.
Are prediction markets taxed the same way?
Not necessarily. Prediction market event contracts trade on CFTC-regulated exchanges, and one treatment argued for them is Section 1256, which nets gains against losses and splits the result 60/40 between long and short term instead of taxing gross winnings. That treatment is unsettled: there is no IRS guidance and no court ruling on event contracts specifically, so it is a position to weigh with a tax professional rather than a settled rule.
