# Prediction Markets and Gambling Sector The newest sector in the vault and the fastest-moving: prediction markets went from FBI-raided gray market to a CFTC-blessed, Trump-family-advised industry worth tens of billions in under two years — while functioning as an end-run around state gambling regulation and, increasingly, as America's de facto election forecasting infrastructure. Casino money remains the old-money wing of the same politics. ## The duopoly **[[Kalshi]]** is the leader (~$21B monthly volume, ~57% share, $2B+ annualized revenue): valued at $2B in early 2025, $22B by March 2026, and reportedly raising at ~$40B by mid-2026 — with [[Donald Trump Jr.]] as paid strategic advisor since January 2025. **[[Polymarket]]** ran the redemption arc: Shayne Coplan's apartment was raided by the FBI in November 2024, DOJ/CFTC closed their investigations without charges in July 2025, and the company bought its way back into the US market via the CFTC-licensed QCEX exchange (~$112M; CFTC approval for brokered U.S. access November 2025). NYSE parent [[Intercontinental Exchange]] committed up to $2B (October 2025) and has put in about $1.6B. Then [[Donald Trump Jr.]]'s [[1789 Capital]] led a **$1B round at ~$21B** (August 31, 2026), with Trump Jr. on the advisory board. He advises both sides of the duopoly — the house always wins, and so does he. [[Trump Media and Technology Group]]'s own entry, "Truth Predict" (built with [[Crypto.com]]'s derivatives arm), was **scrapped in August 2026** in favor of a marketing tie-in with Crypto.com's app. Founder profile: [[Shayne Coplan]]. ## The regulatory end-run The business model is jurisdictional arbitrage: sports "event contracts" under exclusive [[CFTC]] jurisdiction reach bettors in states where sportsbooks are illegal (California, Texas), bypassing state licensing, taxes, and tribal compacts. Sports are now ~70% of Kalshi's activity. The litigation map has hardened into a circuit split. The Third Circuit sided with Kalshi in New Jersey (April 2026). The Ninth (Nevada, August 28) and Sixth (Ohio and Tennessee, September 25) sided with the states, and the question is headed to the Supreme Court (table on [[Kalshi]]). Kalshi separately beat California tribes' challenge under the Indian Gaming Regulatory Act. The regulator itself was nearly captured outright: Trump nominated Kalshi board member [[Brian Quintenz]] to chair the CFTC before the White House withdrew the nomination on October 1, 2025 (the [[Winklevoss Twins]] helped sink it). Quintenz is now a senior adviser to the industry's trade group, and Polymarket's advisory board is chaired by former CFTC chairman [[J. Christopher Giancarlo]]. Under [[Michael Selig]], the CFTC went further than defending its turf: in April 2026 it **sued Illinois, Arizona, Connecticut and New York** to stop them enforcing gambling law against prediction markets. The states are pushing back: Nevada won an injunction against Polymarket in June 2026, and New York sued Polymarket on September 24 (see [[Sports Betting]]). Congress is circling with integrity bills (Blumenthal, Gillibrand) after a wave of insider-trading cases — including congressional candidates suspended by Kalshi for betting on their own races. ## The incumbents pile in The regulated gambling industry, rather than fighting, joined: [[Robinhood]] ran its prediction hub on Kalshi rails (more than half of Kalshi's volume in Q2 2025 — retail brokerage as betting terminal) before moving to its own exchange, Rothera, in mid-2026; [[DraftKings]] launched DraftKings Predictions (December 19, 2025, 38 states, on CME, with its Railbird exchange to follow); and [[FanDuel]] Predicts followed with CME (December 22, 2025) after FanDuel and DraftKings quit the American Gaming Association and gave up on Nevada. [[Fanatics]] Markets launched in 24 states with [[Crypto.com]] (December 2025). The platforms lobby as the [[Coalition for Prediction Markets]]. Meanwhile [[Miriam Adelson]]'s [[Las Vegas Sands]] wing plays the long game in statehouses: after her ~$106M+ to [[Preserve America PAC]] in 2024, Sands-backed PACs poured ~$10M into 2026 Texas primaries to elect casino-legalization legislators, with a Dallas arena-casino complex as the prize. ## Markets as political infrastructure Since Kalshi v. CFTC (2024) legalized election contracts, prediction markets have become midterms infrastructure: 2026 cycle volume is projected past $5B, with the markets pricing Democratic House control around 78–81% as of mid-2026 (see [[2026 Midterms Hub]]). The open questions the vault tracks: manipulation and insider trading (a Polymarket user cleared $400K+ on the Maduro capture), thin-market distortion of media narratives, and what it means that the president's son advises the platforms pricing his party's odds. ## The gambling side - [[Sports Betting]] — how the legal market was built after [[Murphy v. NCAA]], its 2025 numbers ($166.9B wagered, $17.0B kept), the federal-versus-state war over event contracts, the 2025 NBA and MLB rigging cases, the industry's $72M+ in 2026 political money, and the SAFE Bet Act. - [[Problem Gambling]] — the UCLA/USC finding that bankruptcies rose 25–30% in states with online betting, the counter-study, and why prediction markets slip past self-exclusion and age limits. ## Coverage gaps Built 2026-10-03: [[Shayne Coplan]], [[Intercontinental Exchange]], [[J. Christopher Giancarlo]], [[Brian Quintenz]], [[Sports Betting]], [[Problem Gambling]].
