Tax rules are complex, individual, and — for prediction markets specifically — still evolving. Nothing here is a substitute for advice from a qualified tax professional who knows your full situation. Use this as background before that conversation.
Prediction markets have grown quickly, and tax guidance has not fully caught up. What is clear is that if you make money trading them in the US, that income generally matters for tax; what is less settled is exactly how it should be classified. This guide covers what is broadly understood, and flags where the genuine uncertainty lies.
Are winnings taxable?
As a general rule, yes. For US taxpayers, net profit from prediction-market trading is typically treated as taxable income and is expected to be reported, just like other income. That holds whether the platform is a regulated exchange or not, and whether or not you receive any paperwork. The safest assumption is that your net gains are reportable, and to plan for the tax accordingly rather than being caught out later. Our tax estimator gives a rough sense of the amount.
Will you get a tax form?
Possibly. Regulated US platforms can issue tax forms — such as a 1099 — reporting your proceeds or activity to you and to the tax authorities. If you receive one, the information on it has already been shared with the IRS, so your own reporting should line up with it. Crucially, the absence of a form does not mean income is untaxable: you are generally responsible for reporting your gains regardless of what paperwork arrives, which is why your own records are so important.
How prediction-market gains are taxed
This is where the genuine uncertainty sits, and where general guidance can only take you so far. Because these are a relatively new instrument sitting between financial markets and betting, how gains should be classified is not fully settled, and it can depend on how the specific contracts are characterised and on your individual circumstances. Different treatments have been discussed, and the right answer for you is fact-specific.
Rather than guess at a category, the sensible approach is to keep complete records and let a professional determine the correct treatment for your situation. Two people with similar-looking activity can end up in different places depending on the details, so a definitive rule of thumb would do more harm than good here.
Keep good records
Whatever the eventual treatment, thorough records make everything easier. Keep a log of every position — the market, dates, amounts staked, proceeds, and fees — so you can calculate your net result and support it if asked. This is the same discipline that makes you a better trader, covered in our record-keeping guide. Remember too that tax is often federal and state: your state may tax this income on top of any federal liability.
Assume your net winnings are taxable, keep detailed records, expect that a regulated platform may report your activity, and get advice from a qualified tax professional on the correct treatment — especially while the rules for prediction markets are still developing.
Frequently asked questions
Do you pay tax on prediction market winnings?
In general, yes. For US taxpayers, net winnings from prediction markets are typically treated as taxable income and need to be reported. The details depend on your circumstances, so confirm your position with a qualified tax professional. This is general information, not tax advice.
Will I get a tax form from a prediction market?
You may. Regulated US platforms can issue tax forms (such as a 1099) reporting your activity or proceeds to you and to the tax authorities. Whether or not you receive a form, you are generally responsible for reporting your income, so keeping your own records matters.
How are prediction market winnings taxed?
This is genuinely unsettled. Depending on how the contracts are characterised and on your own situation, gains may be treated in more than one way, and your state may tax them as well. Because the treatment is evolving and fact-specific, this is exactly the kind of question to take to a qualified tax professional.
