Tax reporting for Polymarket traders
Polymarket won't send you a 1099. Resolver does the math anyway.
Link your wallet and Resolver syncs your trade history, tracks FIFO cost basis, and computes realized gains under whichever tax treatment fits how you trade — gambling or capital gains.
The tax report Polymarket won't send you
Polymarket issues no 1099 — every trade, redemption, and abandoned position is on you to track. Resolver computes FIFO cost basis and realized gains under whichever US tax treatment actually fits your trading.
Every position, synced automatically
Link your Polymarket wallet once and Resolver keeps your trade history and daily position snapshots up to date, with an on-demand live refresh whenever you want current values.
Read-only by design
Resolver connects with your public wallet address, never a private key or trading credential. It can't place orders or move funds — it only reads what's already public.
