OKX Ventures and Korea Investment & Securities (KIS) will invest 80 billion won each (about $53 million) in Coinone, buying a combined 19.6% stake in a transaction totaling roughly $106 million. The deal is pending regulatory approval. Coinone CEO Cha Myunghun will remain the largest shareholder with a 27.8% stake. OKX Ventures and KIS will become joint third-largest shareholders. KIS is positioning for opportunities in security tokens and stablecoins as Korea’s digital-asset regulatory framework takes shape. OKX Ventures is expected to contribute its global compliance and risk-management expertise. The investment comes amid broader institutional moves into Korea’s regulated crypto sector. Three Samsung affiliates this week reportedly moved to acquire a stake in Upbit operator Dunamu for about $408 million. Mirae Asset has also been pursuing a 92% buyout of Korbit since February. The flurry of deals is fueling speculation that Korea’s compliant exchanges are increasingly being treated as institutional-grade assets.

CME Group has rolled out near round-the-clock trading for cryptocurrency futures and options on its Globex platform starting May 29, according to CoinDesk, aligning regulated-market hours more closely with crypto's always-on trading cycle. The extended schedule covers contracts tied to XRP, Bitcoin and Ethereum, and also brings additional tokens into the nearly continuous session, including Solana, Cardano, Chainlink, Stellar, Avalanche and Sui. Under CME's timetable, crypto derivatives shift into continuous trading at 4:00 p.m. Friday and remain largely available through the weekend, with at least a two-hour system maintenance window. The change allows institutional investors to hedge, rebalance and manage risk during weekends and holidays rather than waiting for traditional market hours to reopen. Trades executed on weekends and holidays will still be settled, cleared and reported on the next business day, as CME keeps its existing back-office processing schedule while extending front-end trading to almost 7×24. Beyond Bitcoin and Ethereum, CME said the expansion reflects growing institutional appetite for risk-management tools across a broader set of crypto assets. The notional trading volume of XRP futures over the past year totaled $62.87 billion. In 2025, notional volume across crypto futures and options reached about $3 trillion. Tim McCourt, CME's head of Global Equities, Foreign Exchange and Alternative Products, has previously said client demand for cryptocurrency risk-management tools has accelerated, supporting continued growth in related futures and options activity. CME views near 24/7 access as a response to volatility that can emerge when traditional markets are closed, and as a step that may narrow weekend-to-weekday price gaps, improve cross-time-zone liquidity and bring regulated-market price discovery closer to on-chain and spot-market tempo.

CME Group, headquartered in Chicago, plans to introduce round-the-clock trading for its cryptocurrency futures and options.

CoinMarketCap reports that Kalshi has received approval from the U.S. Commodity Futures Trading Commission (CFTC), making it among the first firms authorized to offer Bitcoin perpetual contracts in the United States. The decision creates a regulated onshore route for crypto-derivatives trading, bringing a product long dominated by offshore venues into the domestic market. Kalshi said the CFTC has permitted it to list and trade a Bitcoin reference-based perpetual contract under the ticker BTCPERP. The regulator requires the product to remain in ongoing compliance with the Commodity Exchange Act and other applicable rules. Perpetual contracts, unlike standard futures, do not have an expiration date, allowing positions to be held indefinitely. The CFTC also issued a no-action letter to Coinbase, allowing its perpetual futures products to accept Bitcoin, Ethereum and stablecoins as collateral. Those products will be processed through Coinbase Bermuda and treated as offshore futures products for eligible customers. Kalshi CEO Tarek Mansour said the launch marks the company's move beyond prediction markets into regulated derivatives trading. Kalshi continues to address regulatory disputes tied to prediction markets, including ongoing litigation in Minnesota.

President Donald Trump said the United States will lift its naval blockade as part of terms requiring Iran to permanently abandon any pursuit of nuclear weapons and immediately reopen the Strait of Hormuz to unrestricted international shipping. Under the proposed arrangement, the blockade would be eased to allow commercial vessels to depart while Iran completes the removal of remaining maritime mines in the Gulf. Trump added that no financial transfers will be authorized until further notice, as he heads to the Situation Room for a final decision.
