Prediction markets<\/strong> exploded in popularity over the past two years, and now millions of Americans face a new tax puzzle. Platforms like Polymarket<\/strong> and Kalshi<\/strong> let you bet on everything from elections to economic data, but the IRS treats these trades differently than stocks or crypto. Understanding what is a prediction market<\/strong> and how to report your gains is critical before April 15 rolls around.<\/p>\n

A prediction market definition<\/strong> is simple: it’s a platform where you buy and sell contracts that pay out based on whether a real-world event happens. If you think inflation will hit 3% next quarter, you buy a “Yes” contract. If you’re right, the contract settles at $1. If you’re wrong, it’s worth zero. This binary structure makes prediction market basics<\/strong> feel like betting, but the IRS sees them as either commodity contracts or miscellaneous income depending on the platform.<\/p>\n

Kalshi 1099-MISC vs swap treatment<\/h2>\n

Kalshi<\/strong> is a CFTC-regulated exchange, so your trades fall under commodity rules. Most users receive a 1099-MISC for net winnings rather than a traditional brokerage 1099-B. That means you report your total profit as “Other Income” on Schedule 1, line 8z, unless you elect mark-to-market accounting under Section 1256. The catch? Section 1256 gives you 60\/40 capital-gains treatment (60% long-term, 40% short-term) even if you held contracts for one day, but you must file the election by your tax return due date.<\/p>\n

Where each platform issues forms<\/h3>\n

Kalshi mails 1099-MISC forms to any user who nets $600 or more in a calendar year. Polymarket<\/strong>, built on the Polygon blockchain, does not issue tax forms because it operates offshore. You are still legally required to self-report every trade, but the platform won’t send a summary to the IRS. Always download your transaction history in January and reconcile it against your wallet records.<\/p>\n

Polymarket self-reporting basics<\/h2>\n

Polymarket operates as a decentralized protocol, so you track every buy and sell manually. Each winning contract is a taxable event when you redeem it for USDC. Your cost basis is what you paid for the contract, and your proceeds are the $1 settlement value. If you bought a “Yes” contract at 65 cents and redeemed it at $1, you report 35 cents of short-term capital gain on Schedule D. Losing contracts create capital losses, which offset gains up to $3,000 per year against ordinary income.<\/p>\n

Wash-sale considerations<\/h2>\n

The wash-sale rule blocks you from claiming a loss if you repurchase a “substantially identical” security within 30 days. In 2026, the IRS has not issued formal guidance on whether prediction market contracts qualify as securities. Most CPAs advise caution: if you sell a “Biden wins” contract at a loss and buy it back two days later, the IRS may disallow the loss. Crypto traders learned this lesson the hard way, and prediction markets<\/strong> may follow the same path as regulations tighten.<\/p>\n","protected":false},"excerpt":{"rendered":"
