Polymarket x Spark: Instant Bitcoin Deposits
Polymarket now supports instant Bitcoin deposits over Lightning, powered by Spark, making funding your account faster, cheaper, and more private than a standard on-chain Bitcoin transaction.
Polymarket, the world's largest prediction market, now supports instant Bitcoin deposits over the Lightning Network, powered by Spark. Deposits that used to require an on-chain transaction and confirmation wait now settle in seconds, at near-zero cost.
What's New
Polymarket users can now deposit Bitcoin directly via Lightning. Compared to a standard on-chain BTC transaction, Lightning deposits are:
- Faster: funds arrive in seconds, not 30 minutes to an hour
- Cheaper: near-zero fees instead of on-chain network fees
- More private: no public on-chain footprint tied to your deposit
Deposits work out of the box with the apps and exchanges people already use, including Cash App, Coinbase, Kraken, Binance, OKX, Wallet of Satoshi, Tether Wallet, Cake Wallet, and many others. Withdraw over Lightning from any of them and your balance is ready on Polymarket almost instantly.
This is just the beginning: we're working closely with the Polymarket team to expand their on-chain Bitcoin infrastructure and build a world-class Bitcoin experience with more to share in the months ahead.
Why Spark?
Integrating Lightning has historically meant wrestling with liquidity, node management, and channel complexity. Spark abstracts all of it away: Polymarket gets full Lightning interoperability with none of the operational overhead, and users get an experience that feels like a modern payment app while staying native to Bitcoin.
More broadly: as a platform scales, getting Bitcoin infrastructure right (on-chain, Lightning, and everything in between) stops being optional. Hundreds of millions of people hold Bitcoin, including the super users who make the biggest deposits, and they expect to move it instantly wherever they go. Spark makes supporting them the easy default.
