Event-contract exchanges such as Kalshi that let users take positions on sports, elections, politics and other real-world outcomes.
Bitcoin came within $650 of its $87,177 Friday high on Sunday while weekly US spot ETF inflows fell to about $83 million from $2.39 billion. October's seasonal record now has to carry a rally that fund money is backing at a fraction of September's pace.
Reality
Datafolha has Lula at 42% and Flavio Bolsonaro at 38% before Sunday's vote, both short of the 50% that avoids a runoff. Holders of Brazilian assets now carry election risk past Sunday into a second vote that the first-round lead does little to settle.

D. Todd Christofferson, one of the Latter-day Saints' three top leaders, called prediction markets gambling that yields "nothing of value." The speech sets the Utah-based church against the Trump administration's view that Kalshi and Polymarket are not gambling.
Reality
Polymarket has taken $77,507 in positions on whether the world's biggest banks, HSBC and Lloyds among them, fail by year-end. For British lenders the exposure is how fast that price could travel on social media during a period of stress.
Reality
Economist Victor Matheson puts 2025 US sports betting on prediction markets at $50 billion to $100 billion, handle that state regulators cannot see. Kalshi's pending federal appeals will shape whether that money stays outside state gambling law.
Reality
Judge Martha Pacold on October 2 partly enjoined Illinois licensing of Kalshi and Coinbase sports contracts as likely preempted by federal law. Illinois' transaction fees went to further briefing, so the per-trade cost of serving the state is still unsettled.
Reality
Fed policymakers raised rates 12-0 to 3.75%-4% on Sept. 16, and 16 of 18 projected at least one more quarter-point hike this year. Long yields have since risen more than the hike itself, so borrowers have more reason to plan around that projection than around President Trump's complaint.
Reality
South Korea replaced its Prosecutors' Office with two agencies on October 2, leaving prosecutors able to charge but no longer investigate. Anyone facing a serious-crimes probe now deals with investigators at one agency and a charging decision at another.
Reality
CFTC sent the White House two rules on Sept. 28 that would define event contracts as swaps and carve out casino-style gambling products. The agency is trying to settle by rule a state-federal fight that has split appeals courts and now sits before the Supreme Court.

Myriad traders give Bitcoin 48% odds of touching $90,000 in October, a 7.4% climb that is half the month's median gain since 2013. Rates explain that discount better than fund flows do, since September's spot-ETF buyers have so far barely sold.
Reality
Prediction-market odds of a US diesel export ban by October 31 fell to 9.5% from 20% in a day, with diesel at nearly $6.50 a gallon, close to a record. Republicans want relief a month before the midterms, yet traders now price a ban before the contract settles as a long shot.
Reality
Bitcoin rose 0.9% to $84,376 after August core PCE came in at 3.0%, below the 3.3% economists expected. Lower odds of an October Fed hike did little for a market whose September rally ran on ETF inflows that have since faded.

Kalshi is in advanced talks to raise about $1 billion at a $40 billion valuation, 3.6 times the $11 billion it was worth in December 2025. Most of the volume behind that price comes from sports contracts, so the new investors are betting that regulators and courts keep allowing them.
Reality
Former Representative Adam Kinzinger is under CFTC investigation over Kalshi bets on his own pardon that made him $823, Politico reported. Exchanges listing markets on named people must now decide whether being a contract's subject is enough to bar a trade.

Kalshi will end its volume rebate on or after October 13 as the CFTC reportedly reviews over $5 billion in repeated ether perpetual trades. Kalshi says paid market makers produced those prints, leaving investors at a $40 billion valuation to judge how much liquidity was bought.
Reality
Polymarket launched opt-in deposit limits, self-exclusion and mental-health referrals on September 30, six days after New York sued it over sports contracts. The tools come alongside its federal-court claim that commodity law overrides the state's gambling statutes.
Reality
Polymarket has added deposit caps users cannot reverse, plus self-exclusion, after sports and parlays took over 98% of its September trading volume. Kalshi, which the CFTC regulates, already offered the same tools, so they help Polymarket defend itself in New York's gambling suit as much as they make it look like a sportsbook.
Reality
Polymarket, valued at about $21 billion, hired ex-Goldman partner Lisa Mantil to bring big traders onto its US exchange. She starts selling while federal investigators, House members and New York officials still dispute how its contracts should be policed.
Reality
Kalshi took $15.8 billion of the $20.4 billion prediction markets traded last week, per Artemis, the first week above $20 billion. It books each contract at its $1 payout, so the record counts payouts written, well above the cash traders put at risk.
