How Realize was born

For years we’ve built products that help sports bettors and traders keep more of their own money. It’s the whole idea behind trylayup.com. Along the way we kept noticing the same thing: people were quietly losing money at tax time.

Prediction markets made it worse. The trades sit on a CFTC-regulated exchange, but the exports are raw and the tax treatment is unfamiliar, so most filers, and plenty of CPAs, leave real money on the table every April.

So we spoke with hundreds of bettors and traders. The pattern was hard to miss: for a lot of them a refund isn’t an abstraction. It’s rent, a flight home, a little breathing room. Getting money back just makes people’s lives better.

That’s why we built Realize. Connect your account read-only, and we turn years of raw trades into transparent, traceable tax figures. We don’t promise a magic number. We show the work, cite current federal precedent, and hand you and your advisor something you can review and stand behind.

Building in public

Straight from the founder.

We share what we’re learning about prediction-market taxes as we build. Here are a few of the latest.

What we build by

Trust is the product, not a badge.

Transparency over correctness

We don't promise a guaranteed-right return. We organize and compute, show our work, and make every figure trace back to the underlying trades, so you and your CPA can review it and file with confidence.

Read-only, least access

We never ask for write access to your account. We guide you to a read-only connection so we can read your trade history. We can’t place trades or move your money.

Clear about what’s unsettled

The tax treatment of prediction-market contracts is genuinely new. We write to current federal precedent, show the reasoning, and flag the open questions honestly. We never overstate certainty.

Your data stays yours

We use your trade history to generate your tax figures and nothing else. No ad networks, no resellers, no selling your data.
