Prediction markets were May's breakout theme — but the story that mattered wasn't volume, it was jurisdiction. In a single month, the CFTC moved to claim regulated prediction markets as federal futures while the SEC stalled two dozen related ETFs and a widening list of states and foreign regulators moved to shut them down. The bull case and the existential risk arrived at the same time, which is exactly why the cross-source read on the sector landed neutral rather than euphoric: the same calendar that legitimized these venues also put their right to operate on trial. ## The CFTC's claim The clearest throughline of the month was a federal regulator planting a flag. The CFTC sued Minnesota over its prediction-market ban [[1]](/s/HOqvRm79QWeVtH66oYKtcA), filed in support of Kalshi in an Ohio dispute [[2]](/s/G5OFNUpIQkmKBlCrxRqJBg), and granted no-action relief that let a regulated market operate [[3]](/s/x1efYbInSUiDBd8RHqXKSg). It moved to streamline prediction-market rules after fielding more than 1,500 comments on its rulemaking [[4]](/s/MYiKqf2-Q7elWKDOva55Dg)[[5]](/s/RsThN_O2TLq9i42yJcFZ_w), and it reaffirmed jurisdiction in a Sixth Circuit brief [[6]](/s/X2CgFuHNT5iehR7vKsCLkQ). The capstone was approval of the first Bitcoin perpetual futures on Kalshi — a first-of-its-kind endorsement that, our sources noted, frames these venues as regulated financial infrastructure rather than novelty [[7]](/s/UrBEEdpgReObDUu3z_UGrQ). The White House was reported to be reviewing the CFTC's prediction-market rulemaking with administration backing [[8]](/s/KnMdWtkeSCmFiqPBeBItXQ). ## The SEC's hesitation The other federal agency pulled the opposite way. The SEC delayed roughly two dozen prediction-market ETFs set for a near-term debut [[9]](/s/GErq1oeZQv-WKSIUbug2cg)[[10]](/s/82iIn_Z-RIWj2h4FZvBHyw), a move flagged across publications and by an ETF-focused insider as a brake on the institutional on-ramp [[11]](/s/nLegLu_dSnGQsL9MdQXfuA). The split-screen — one regulator approving perpetuals while another stalls fund wrappers — is the cleanest illustration of how unsettled the sector's federal status remains [[7]](/s/UrBEEdpgReObDUu3z_UGrQ)[[10]](/s/82iIn_Z-RIWj2h4FZvBHyw). ## The bans While Washington argued over how to regulate, others moved to prohibit. Minnesota became the first US state to ban prediction markets outright, prompting an immediate federal suit and a separate challenge from Kalshi [[12]](/s/6kYgqo7-Ts6AwMp9ZKGFJw)[[13]](/s/sAGzu8jpSuyy-XJlWkyv0g). Abroad, Spain blocked the two largest event-trading platforms for operating without licenses [[14]](/s/-WiMIRFvQKCSZI_CrPrxig) and Indonesia blocked a leading venue on gambling-law grounds [[15]](/s/Lv9Pu1IJTXmRxT3_dKqAsQ). Domestically, two of the largest platforms lost legal bids to halt gambling cases in Nevada and Washington [[16]](/s/awmZ3-fmTCGfp5g08rrJdg). The pattern across May: federal legitimization and sub-federal prohibition advancing in parallel. ## Integrity questions The month also surfaced the sector's governance gap. A House Oversight committee opened a probe into insider trading on the two largest platforms [[17]](/s/apPVXO1ZSNqwRJrOrqWDJg), and a Google engineer was charged in a $2.75M insider-trading case tied to a leading event-trading venue [[18]](/s/NWPq1UVqT06V28sm4Vnr0w). In response, the CFTC and the NHL signed a data-sharing MOU aimed at safeguarding sports-related prediction markets [[19]](/s/cRuElbzEQ9K_tvEWPy1OSw)[[20]](/s/rKsC7vy-QXWIbNz7YKBWJQ), and one venue addressed a suspected exploit of a UMA oracle adapter on Polygon [[21]](/s/ML-2ifIXRd-akeI1O4ehLQ). These are the integrity problems that arrive once a market is large enough to be worth gaming. ## Institutionalization, in the same breath Underneath the legal noise, the sector kept maturing. Market maker Wintermute began providing liquidity to the leading prediction-market venues [[22]](/s/gz7pzkEXT1y1OpBItIHXHw)[[23]](/s/FLi0NSnBRrSFdof_vNVA-Q), Hyperliquid launched validator-governed prediction markets [[24]](/s/v_tJa3s7RVuGAX0VCQb2Ew), and a major platform extended into markets for private-company IPOs and valuations [[25]](/s/KLe5TnN8TmWdyZe0UPY4JA) and named an executive to lead a Japan expansion [[26]](/s/JnPzDr71Q8ei8MXE7wlI0A). Gemini reported prediction-market metrics alongside 42% revenue growth [[27]](/s/gjfUdAmLS32j1RZLs6qUsQ), and esports reportedly grew to 27% of one platform's sports volume [[28]](/s/StspzrvYS9K7MnIOQdAFmg). To raise its policy profile, Kalshi launched an advocacy group, Americans for Fair Markets, to promote prediction markets [[29]](/s/-snANUv1RKCVGGAD-c9e9w). ## The open questions May leaves the sector at a fork: a federal regulator treating these venues as legitimate futures markets, a second federal regulator withholding the ETF wrapper, and a growing list of states and countries trying to close them. Whether the CFTC's jurisdictional claim holds in court [[1]](/s/HOqvRm79QWeVtH66oYKtcA)[[6]](/s/X2CgFuHNT5iehR7vKsCLkQ), and whether the integrity probes reshape how these markets police themselves [[17]](/s/apPVXO1ZSNqwRJrOrqWDJg)[[19]](/s/cRuElbzEQ9K_tvEWPy1OSw), will decide if May was the month prediction markets graduated — or the month their growing pains went public. --- *MoonWire surfaces and summarizes public crypto news.* **General information only — not financial advice.** MoonWire Ltd. is not licensed by ASIC and holds no AFSL.
