The upgrade replaces a funding flow that previously took anywhere from 10 to 60 minutes, with the new route crediting deposits in under a second with near-zero fees.<\/p>\n<p>The change is a sharp departure from the standard onchain <span>bitcoin<\/span> deposits Polymarket added in October 2025, which required three to six network confirmations before the platform credited an account. They carried a higher minimum deposit that reflected bridging costs, but the Lightning route changes that status quo, settling transactions in seconds while keeping minimums low.<\/p>\n<p><\/p>\n<p>Tether CEO Paolo Ardoino, whose company issues the <span>USDT<\/span> <span>stablecoin<\/span>, praised the underlying technology, describing it as:<\/p>\n<blockquote>\n<p>\u201cA route to programmable <span>Bitcoin<\/span> over Lightning.\u201d<\/p>\n<\/blockquote>\n<h2>How Spark\u2019s Zero-Conf Rails Work<\/h2>\n<p>Spark was developed by Lightspark and is built on statechain technology, a design that moves <span>bitcoin<\/span> ownership off the main chain while preserving user custody. The protocol validates a <span>bitcoin<\/span> transaction at the moment it is broadcast, checking for double-spend risk, fee adequacy, and replace-by-fee flags before crediting the deposit.<\/p>\n<p>The structure also lightens Polymarket\u2019s operational load as the platform does not have to manage confirmation thresholds or run its own Lightning <span>nodes<\/span>, because a single Spark software development kit (SDK) handles onchain, Lightning, and <span>stablecoin<\/span> rails. Deposits remain self-custodial, with each wallet tied to the user\u2019s own keys, so traders retain control of their funds until they place a trade.<\/p>\n<p>As things stand, wallet providers including Breez, Xverse, and Cake are building on the protocol, indicative of the fact that instant <span>bitcoin<\/span> settlement could become a standard feature across consumer <span>crypto<\/span> apps rather than a niche add-on.<\/p>\n<h2>A Funding Arms Race With Kalshi<\/h2>\n<p>The upgrade lands in the middle of an intensifying battle for <span>prediction market<\/span> <span>volume<\/span> as rival exchange Kalshi posted <a href=\"https:\/\/news.bitcoin.com\/prediction-market-traders-push-april-2026-volume-to-8-6b-kalshi-takes-the-lead\/\">$5.42 billion in April taker volume<\/a>, overtaking Polymarket\u2019s $1.99 billion for the first time as the sector\u2019s monthly total hit $8.6 billion.<\/p>\n<p>The latter also recently unveiled <a href=\"https:\/\/news.bitcoin.com\/polymarket-unveils-perpetual-futures-trading-for-us-markets-in-2026\/\">perpetual futures trading<\/a> for U.S. markets, broadening its offering beyond simple event contracts as it works to reclaim ground from its regulated rival.<\/p>\n<p> <span>Bitcoin<\/span> deposits give Polymarket access to the deepest pool of capital in <a href=\"http:\/\/www.bitcoin.com\/get-started\/a-quick-introduction-to-crypto\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">crypto<\/a> and by meeting <a href=\"https:\/\/www.binance.com\/en\/price\/bitcoin\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">bitcoin<\/a> holders where they are, the platform is removing a conversion step that previously pushed some would-be depositors toward <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-are-stablecoins\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">stablecoin<\/a> funding instead.<\/p>\n<p>With Kalshi setting monthly records and both platforms courting the same pool of traders, deposit speed, fees, and asset coverage are likely to decide where the next wave of <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-are-prediction-markets\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">prediction market<\/a> capital lands.<\/p>\n<\/p><\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/polymarket-switches-on-instant-bitcoin-lightning-deposits-cutting-60-minute-waits-to-under-a-second\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways Polymarket now credits bitcoin Lightning deposits in under 1 second via Spark, versus 10\u201360 minutes onchain.
