Kalshi launched in 2021 as the first CFTC-regulated prediction exchange in the US. It's a legitimate product — but it's built for US residents with a US bank account. If you're outside the US, you simply cannot use Kalshi.
PolyGram has no geographic restrictions. You can sign up from anywhere, deposit USDC via Polygon in minutes, and trade on the same prediction markets — without submitting government ID, without a US bank, and without paying maker/taker fees on every trade.
The 0% house edge is structural: PolyGram uses a Central Limit Order Book (CLOB) model where prices are set by supply and demand from other traders. Kalshi charges a fee on every side of every trade, which compounds significantly on active accounts.
Kalshi's fee schedule: 0% maker fee + 0.35%–1% taker fee depending on volume tier. On a $100 trade this costs $0.35–$1.00 per fill. On $10,000/month volume: $35–$100 in fees.
PolyGram charges no platform fee. Revenue comes from the spread between your fill price and the live CLOB price — which mirrors exactly what you'd pay on Polymarket, but with PolyGram's Telegram-native UX, copy-trading, and VIP rakeback on top.
No. Kalshi requires you to be a US resident and to complete full KYC (identity verification) with a US address. Non-US residents are blocked at registration. PolyGram has no geographic restrictions and supports users worldwide.
Kalshi is regulated by the CFTC (US Commodity Futures Trading Commission). PolyGram operates as a decentralised prediction market using on-chain settlement via the UMA oracle on Polygon — no central counterparty, fully transparent. Regulatory environment for crypto prediction markets varies by jurisdiction; always check your local laws before trading.
PolyGram provides access to 500+ live prediction markets spanning politics, crypto, sports, and pop culture via the Polymarket CLOB API. Kalshi offers around 200 markets, primarily focused on US economic and political events.
