Wintermute&#8217;s Head of OTC Trading, Jake Ostrovskis, described current liquidity conditions in prediction markets as having &#8220;the demand profile of a major asset class but the liquidity profile of an early-stage one.&#8221; The firm&#8217;s stated goal is to tighten bid-ask spreads and deepen order books enough to support institutional-scale position sizes without significant price impact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The move arrives as the sector posts numbers that are increasingly difficult to dismiss. Prediction markets have cleared more than <strong>$60 billion<\/strong> in cumulative trading volume in 2026, with monthly turnover on leading platforms now running above <strong>$20 billion<\/strong>, <em>per Wintermute&#8217;s own figures<\/em>. Kalshi alone has seen its annualized volume surge from <strong>$52 billion<\/strong> to <strong>$178 billion<\/strong> in the six months through early 2026, with the CFTC-regulated venue now accounting for over <strong>90%<\/strong> of U.S. prediction market activity. Lifetime combined volume across Polymarket and Kalshi has crossed <strong>$150 billion<\/strong>, <em>according to data cited by The Block<\/em>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wintermute joins Jump Trading and Galaxy Digital, both of which already provide liquidity on event contracts, <em>per The Block<\/em>. The entry of a third major market maker signals a structural shift: prediction markets are no longer niche venues but are beginning to attract the same liquidity infrastructure as crypto spot and derivatives markets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Regulatory pressure is rising in parallel. The CFTC issued an Advanced Notice of Proposed Rulemaking in March 2026 addressing manipulation risks in event contracts. Spain this month became the fifth country to order ISP-level blocks on both Polymarket and Kalshi over unlicensed gambling concerns. At least 11 U.S. states have advanced legislative measures targeting the sector. Kalshi has filed suit in federal court to block a Minnesota law that would criminalize prediction market activity starting August 1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For now, the institutional direction of travel is clear. Wintermute&#8217;s entry effectively treats prediction markets as another derivatives frontier \u2014 one with stablecoin settlement, on-chain clearing, and the kind of automated risk management already standard in institutional DeFi.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wintermute, the London-based algorithmic trading firm that processes more than $3.5 trillion in annual volume, confirmed Friday it<\/p>\n","protected":false},"author":2,"featured_media":401,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[3],"tags":[],"class_list":["post-400","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-market"],"brizy_media":[],"_links":{"self":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/400","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=400"}],"version-history":[{"count":1,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/400\/revisions"}],"predecessor-version":[{"id":402,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/posts\/400\/revisions\/402"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=\/wp\/v2\/media\/401"}],"wp:attachment":[{"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=400"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=400"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/1stblock.info\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=400"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
