Kalshi at $22B, Polymarket Raises $400M, and Our Portfolio Is Up 33.6%

Issue #2 · April 22, 2026 · By John Leslie

This week: Kalshi is valued at $22 billion and heading to the Supreme Court. Polymarket is raising $400M with the NYSE parent company backing it. Meanwhile, IRGC gunboats are seizing ships in the Strait of Hormuz and our fictional portfolio is up 33.6% in two days. The money is flooding in and the stakes keep rising.

The Big Story: The $37 Billion Week

Three developments this week prove prediction markets have crossed from crypto curiosity to financial infrastructure:

1. Kalshi raised $1B+ at a $22 billion valuation

Coatue Management led the round. Kalshi controls 89% of the regulated U.S. market (Bank of America, April 9). At $22B, Kalshi is now valued higher than the Chicago Board Options Exchange was at its 2005 IPO. This is not a bet on prediction markets. It is a bet that event contracts become a permanent asset class.

2. Polymarket is raising $400M at $15 billion

Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, has committed up to $2 billion. When the NYSE parent company writes a $2B check into prediction markets, the institutional legitimacy question is settled. The remaining question is who wins: regulated (Kalshi at $22B) or crypto-native (Polymarket at $15B)?

3. The Supreme Court is next

Kalshi's fight with states over whether prediction markets are derivatives or gambling is heading toward the Supreme Court. The outcome determines whether the industry operates under one federal framework (CFTC) or 50 state gaming commissions. Sports betting is currently 85% of volume for both major platforms. If the Court rules prediction markets are gambling, those contracts vanish overnight. If it rules they are derivatives, the CFTC becomes the sole regulator and institutional capital pours in.

What this means: The prediction market industry is expected to hit $200B in volume this year. Bernstein projects $1 trillion by 2030. The infrastructure war between Kalshi and Polymarket will define market structure for the next decade. For traders: enjoy the promotional pricing and tight spreads. This is two platforms spending billions to buy your order flow.


The Markets

Hormuz: IRGC Seizes Two More Vessels

Our call from Issue 1: April normalization at 38% was overpriced (fair value 5-10%), May at 69% was overpriced (fair value 40-50%).

Current prices: April 9% YES, May 59% YES. Both moved sharply in our direction.

The week timeline:

April 17: Iran declares the strait completely open. Oil drops 10%. Markets surge.

April 18: Iran reverses course. IRGC gunboats fire on two Indian-flagged ships. India summons the Iranian ambassador. Iran claims communication gap.

April 19: US Navy seizes Iranian cargo ship Touska after 6-hour standoff. Marines rappel from helicopters. Tehran vows retaliation. Iran parliament drafts a law requiring hostile country ships to get approval and pay tolls.

April 20: Zero tankers cross the strait. One of the quietest days since the crisis began.

April 21: Trump says he will not extend ceasefire. Warns of lots of bombs. US forces board oil tanker M/T Tifani in the Indian Ocean.

April 22 AM: Trump reverses, announces open-ended ceasefire extension, but the blockade stays fully in place. Iran FM Araghchi calls the blockade an act of war and a violation of the ceasefire.

April 22 PM: IRGC seizes two more vessels in the Strait of Hormuz. Negotiations deadlocked. About 800 vessels queued in the Gulf.

Updated call: April is effectively resolved as NO. May at 59% is still overpriced. Revised estimate: 30-40%. The blockade is becoming structural, not tactical. Iran is institutionalizing it with transit fees. The negotiating gap is massive (US wants 20-year enrichment pause, Iran offered 5 years). 3-8 ships per day are transiting vs. 60 needed. This does not unwind in 5 weeks.

Iran Regime Change: The Cheap Hedge

Will the Iranian regime fall by April 30 has $32M in volume despite trading at just 2% YES. Why does a 2% market have $32M?

Traders are using it as a cheap hedge. At 2 cents per share, a YES position is a lottery ticket. If Mojtaba Khamenei (installed as Supreme Leader on March 8 after his father's assassination) faces a coup, that 2-cent share becomes worth $1.

The longer-dated markets:

  • By May 31: 3%
  • By June 30: 7.5%
  • By end of 2026: 20%

The market says there is a 1-in-5 chance of regime change within 9 months.

2028 Presidential: Democrats Still Elevated

$548M in volume. Current top candidates:

  • JD Vance: 18.8%
  • Gavin Newsom: 17.8%
  • Marco Rubio: 10.2%
  • Alexandria Ocasio-Cortez: 5.9%
  • Kamala Harris: 4.1%

Democrats remain elevated, driven by backlash to Iran. Historical base rates suggest regression toward 50/50 this far from an election. I would not trade this either direction until the Hormuz situation resolves.

Eurovision: Finland Still Leads

Finland leads the overall winner market at 36%. Finland is the consensus pick but is not dominant in either the jury (13%) or televote (17%) sub-markets. Israel leads the televote at 38%. At 36%, Finland is probably fairly priced. The value, if any, is in Israel for the televote.


The Feature: Prediction Markets vs. The National Weather Service

The most underrated story in prediction markets right now.

ForecastEx has been offering daily high-temperature markets via Interactive Brokers ForecastTrader since November 2025. Patrick Brown, head of climate analytics at Interactive Brokers, found that prediction markets were more accurate than the National Weather Service.

Why would traders beat meteorologists with billion-dollar supercomputers?

They are not beating them. They are aggregating them. A prediction market on tomorrow's high temperature in Chicago does not replace the weather models. It combines them. Traders who follow the European model, the GFS model, local radar, and even look out the window all contribute to the price. The result is an ensemble of all available information, weighted by confidence.

This is the prediction market thesis in its purest form: markets as information aggregators. Not better than any individual expert, but better at combining all available expertise.

If markets can improve weather forecasting, they can improve forecasting of economic indicators, disease outbreaks, and supply chain disruptions. The category is about to get much bigger.


The Regulatory Corner

Federal wins:

  • CFTC enforcement advisory issued, signaling intent to regulate rather than kill the space
  • Third Circuit ruled prediction markets cannot be regulated by state gambling laws
  • New Jersey lost its appeal against Kalshi on sports contracts

State pushback:

  • Nevada issued a temporary ban on Kalshi
  • Arizona accused the platform of unlicensed gambling
  • Massachusetts secured preliminary injunction
  • 40+ lawmakers led by Sen. Warren pushing for insider trading rules

The insider trading problem:

  • A trader made $400K correctly predicting the Maduro ouster in January
  • Another made about $300K on Biden pardon timing
  • A political candidate was caught trading on his own candidacy (fined $2,246, 5-year ban from Kalshi)

My read: federal primacy wins. The CFTC is suing states, which means they want jurisdiction. Kalshi regulatory moat deepens with each court victory. Long-term bullish for the industry. Short-term, expect volatility around rulings.


Track Record

Market Issue Call Entry Current Status
Hormuz April 1 NO at 38% 38% 9% Virtually resolved. +46.7%
Hormuz May 1 NO at 69% 69% 59% Tracking right. +34.3%

Fictional $1,000 portfolio (started April 20): now worth $1,336 (+33.6% in 2 days). Two calls, both correct direction.
