Common questions from Iowa users
Can I use Polymarket from Iowa with a VPN?
Yes, technically — and the typical US-user path. A non-US IP via VPN plus crypto deposits (USDC on Polygon) gets you a working Polymarket account with no KYC at signup. KYC triggers at fiat offramps, where a US ID can result in restrictions. Keep withdrawals to self-custody crypto wallets if you want to avoid that.
Does Kalshi report my gains to the IRS?
Yes. Kalshi issues 1099s. Gains are federal ordinary income or short-term capital gains depending on activity.
Does Polymarket report my gains to the IRS?
No 1099 from Polymarket. US users are personally responsible for reporting gains.
What happens if Iowa passes its own prediction-market rule?
State-level rules cannot override federal CFTC designation for event contracts — this is the preemption question at the heart of several 2024–2026 court cases between Kalshi and various state regulators. Kalshi has consistently prevailed at federal court level.
