Kalshi the U.S.-based regulated prediction market platform, has announced support for deposits using the Solana (SOL) cryptocurrency.

This new funding option allows users to fund their accounts directly from their Solana wallets, with SOL deposits converting to cash instantly. Kalshi already supports other cryptocurrencies including Bitcoin (BTC), USD Coin (USDC), WLD, RLUSD, and XRP.

The addition of Solana positions Kalshi to expand its presence in the crypto space and compete with platforms like Polymarket. Separately, the Photo Finish game has introduced openTote, a custom smart contract protocol designed for fast, low-cost betting pools with instant settlement, which is launching with the Photo Finish Live off-track betting site and is accessible via a single API for any game or partner. This development is part of the Solana Accelerate 2025 initiative.
