Kalshi recorded its highest monthly trading volume in June as activity surged across prediction markets tied to the 2026 FIFA World Cup. According to Cointelegraph, DefiLlama data shows Kalshi logged nearly $9.4 billion in June trading volume, up from about $5.3 billion in May, while Polymarket International rose to roughly $4.3 billion from about $3.5 billion a month earlier. The tournament, which kicked off on June 11 and is the first FIFA World Cup to feature 48 teams instead of 32, became the biggest driver of prediction-market trading during the month, CNBC reported. Dune Analytics data cited by CNBC showed record notional trading volumes on both Kalshi and Polymarket, with knockout-stage matches drawing some of the strongest interest. Specific Round of 16 markets were among the most active. Canada’s Round of 16 match against Morocco, scheduled for Saturday, had generated over $48 million in trading volume on Kalshi and over $26.8 million on Polymarket at the time of writing. The United States’ Round of 16 match also attracted notable participation, with Kalshi’s market on which team will advance generating more than $2.1 million in volume, while a comparable market on Polymarket drew around $1.6 million as of Saturday. The surge in trading comes as prediction markets face intensifying legal and regulatory scrutiny in the United States. By March, nearly a dozen US states had moved against companies including Kalshi and Polymarket, with some seeking to halt the markets and others aiming to bring them under existing gambling laws and state tax frameworks. Federal regulators have pushed back against state efforts to police prediction markets. The following month, CFTC Chair Michael Selig accused states of pursuing “illegal enforcement actions” against federally regulated exchanges, arguing Congress granted the agency sole authority over commodity derivatives markets, including prediction markets. Selig said that states seeking to nullify federal law and seize authority over these markets would face court challenges. The debate has also expanded beyond regulators. In June, casino operators, tribal organizations, and labor groups urged Congress to remove sports-event contracts from the CFTC’s authority through an amendment to the Digital Asset Market Clarity (CLARITY) Act, arguing such contracts should remain under state gambling laws and existing gaming oversight. In Europe, regulators signaled a different stance: on Friday, the European Securities and Markets Authority reminded firms that many event contracts may already fall under restrictions on binary options, stating regulation depends on a product’s characteristics rather than the “event contract” label.

According to Lianhe Zaobao, Japan’s Immigration Services Agency issued new rules on July 3 to raise visa fees starting in October, as the government seeks to tighten immigration requirements while addressing labor and domestic-demand needs amid a low birthrate. Under the changes, visa fees will rise from the current cap of JPY 10,000 to JPY 33,000 for one year, JPY 48,000 for more than one year up to three years, JPY 64,000 for more than three years up to five years, and JPY 75,000 for more than five years; approved applications for permanent residency will cost JPY 200,000. The report said Japan has more than 4 million foreign residents, most of whom must renew visas periodically. Japanese media also reported that authorities plan to formally make Japanese-language proficiency a condition for permanent residency, including a proposed “Japanese Language Life Learning Program” that would require applicants to take classes and be assessed via exam results. Justice Vice Minister Fukuyama Mamoru said on July 3 the government will set up an expert panel this summer to design the details. The report estimated the visa-fee increase could bring nearly JPY 90 billion in revenue to Japan’s treasury, which authorities said would be used to support immigrant integration, including more Japanese-language classes for immigrants’ children.

According to CNBC, President Donald Trump said he agreed to attend next week’s NATO summit in Turkey after Turkish President Recep Tayyip Erdogan urged him to come, and Trump hinted he could make an announcement related to jet engines and the potential sale of F-35 fighter jets to Ankara. Trump told reporters he would “probably do something” that would make Erdogan “very happy” when asked about a “gift bag,” as Turkey seeks F-110 jet engines and F-35s; Turkey was barred from the F-35 program in 2019 after buying Russia’s S-400 missile defense system. CNBC reported that Vice President JD Vance said the U.S. was exploring ways to sell the jets while ensuring Turkey complied with U.S. law, and that the State Department last week notified key lawmakers it planned to bypass congressional opposition to more than $700 million in F-110 jet engine sales, according to two people familiar with the nonpublic notice.
