A Polymarket took an important step to bring users even closer to Bitcoin. The prediction markets platform now accepts instant cryptocurrency deposits via the Lightning Network, reducing a process that previously took between 10 and 60 minutes to less than one second.
The update removes one of the main barriers for those using Bitcoin on the platform. Until then, deposits depended on blockchain confirmations, which delayed the start of trading and required higher minimum amounts due to network costs.
With the Lightning Network integration, resources are made available in practically real time and with fees close to zero. In practice, this allows traders to move their bitcoins to Polymarket much faster, taking advantage of market opportunities without long waits.
Lightning Network changes the experience for Bitcoin users
The news is enabled by the protocol Spark, developed by Lightspark. The technology verifies several transaction parameters right after it is sent, including the risk of double-spending, the fee level, and indicators related to the replace-by-fee mechanism. After this validation, the deposit can be credited almost instantly.
Tether CEO Paolo Ardoino summarized the technology’s potential by saying:
“A path to programmable Bitcoin through Lightning.”
Spark uses the technology known as statechain, which makes it possible to transfer ownership of bitcoins outside the main blockchain without giving up self-custody. This means that users continue to keep control of their own private keys until they decide to use the assets in trading.
Another benefit lies in simplifying Polymarket’s infrastructure. Instead of running their own Lightning Network nodes or managing blockchain confirmation policies, the platform uses a single software development kit (SDK), responsible for integrating on-chain payments, Lightning, and even transactions with stablecoins.
Bitcoin gains more space within Polymarket
The arrival of instant deposits also removes a step that kept some investors away. Many users needed to convert their bitcoins into stablecoins before sending funds to the platform. Now, that process is no longer necessary, making Bitcoin use far more direct.
The move also expands Polymarket’s access to the largest pool of capital in the cryptocurrency market, made up of Bitcoin holders.
At the same time, other companies in the sector start adopting the same technology. Wallets like Breez, Xverse and Cake are already developing integrations based on the Spark protocol, indicating that instant settlements could become a standard for applications targeting the cryptocurrency market.
Dispute with Kalshi increases pressure for innovation
The update comes as competition between prediction market platforms grows. Kalshi moved US$ 5,42 billion in taker volume during April, surpassing the US$ 1,99 billion recorded by Polymarket. In the same period, the sector reached approximately US$ 8,6 billion in monthly trading.
Beyond the race for market share, Polymarket also expanded its offering by announcing perpetual futures contracts for the United States.
In this increasingly competitive environment, deposit speed, reduced costs, and native support for the Bitcoin become decisive factors for attracting new users and maintaining liquidity within the platform. Integration with the Lightning Network puts Polymarket in a more competitive position precisely by removing one of the biggest obstacles for those who prefer trading using the market’s leading cryptocurrency.
