Hook
Kalshi spent $990,000 on lobbying in the first half of 2025. That is nearly its entire 2024 annual spend. In six months. The number is not a rounding error. It is a declaration of war—filed with the Senate Office of Public Records.
Polymarket, its closest peer, spent $180,000. A fraction. The asymmetry is not an oversight. It is a strategic bet that either Kalshi wins the regulatory battle for both of them, or Polymarket quietly absorbs the fallout.
Traditional casinos increased their lobbying spend by 30% in the same period. Their war chest dwarfs both. The American Gaming Association alone budgets over $5 million annually for political influence.
This is not a market narrative. It is a balance sheet line item. And the alpha is not in the trading volume—it is in the silenced code of campaign finance disclosure forms.
Context
Prediction markets exist in a regulatory gray zone defined by two competing frameworks. Kalshi operates under CFTC jurisdiction as a designated contract market. Its event contracts are classified as derivatives, not gambling. Polymarket, built on Polygon, uses USDC and smart contracts, positioning itself as a decentralized information market. Neither has a native token that captures value. Their business model is pure fee extraction—the platform takes a cut of every trade.
The core legal tension: are prediction contracts "gambling" or "price discovery"? If gambling, state laws apply—and casino lobbies have centuries of precedent. If price discovery, federal commodities law applies—and CFTC oversight is manageable for well-capitalized firms.
The 2022 midterms and the 2024 presidential race created a surge in political event contracts. But the real growth driver has been sports. According to data from Dune Analytics, Polymarket’s monthly active traders in sports markets grew 340% between January 2024 and June 2025. Kalshi does not publish user numbers, but its regulatory filings show a 200% increase in contract volume.
This growth attracted attention. The casino industry sees prediction markets as direct competitors for the same gambling dollar. In June 2025, the American Gaming Association sent a letter to Congress urging lawmakers to classify all event contracts as illegal gambling under state law.
Kalshi’s response: hire the best-connected lobbyists money can buy. Its roster includes former Obama and Biden administration officials. Its advisory board includes Donald Trump Jr. The cost is $1.8 million in total lobbying since 2024—more than any blockchain-native company of comparable size.
Core
Let me walk through the numbers using the methodology I developed for the 2020 DeFi arbitrage scripts. Raw data is only useful if you know where to look.
The first signal is the step-change in Kalshi’s lobbying expenditure.
2024 full year: $1.02 million H1 2025: $990,000 Run-rate: $1.98 million annually
This implies Kalshi expects the next 12-18 months to be decisive. The reason is the Congressional Review Act—if a new administration tries to expand CFTC authority over event contracts, there will be a 60-day window for Congress to overturn it. Lobbying during that window is critical.
The second signal is the ratio of Kalshi to Polymarket lobbying.
Kalshi H1 2025: $990,000 Polymarket H1 2025: $180,000 Ratio: 5.5x
On-chain data from Polygon shows Polymarket has roughly 4x the daily active users of Kalshi. So Polymarket has 4x the user base but spends 1/5th on lobbying. This is a deliberate arbitrage: let Kalshi bear the regulatory cost while Polymarket focuses on product. But it creates a dependency. If Kalshi fails, Polymarket inherits the regulatory attention without the defense.
The third signal is the casino industry’s response.
Traditional gambling lobbying in 2024: $68 million (across all segments) Increase in H1 2025: 30% → run-rate of ~$88 million
That is 88x Kalshi’s spend. Prediction markets are not in the same league. They are playing a different sport.
The leverage point: state-level regulation. The casino industry has deep ties to state legislators and tribal gaming commissions. In February 2025, the Committee on Indian Affairs introduced a bill that would prohibit federally recognized tribes from engaging in prediction market contracts. If passed, it effectively bans the largest potential liquidity pool.
Kalshi’s counter-move: hire lobbyists with ties to the executive branch, not just congress. The appointment of Donald Trump Jr. as advisor is a play for White House influence. The former administration’s CFTC chairman, Heath Tarbert, was a vocal supporter of prediction markets. A second Trump term with a friendly CFTC could create a favorable regulatory glide path.
But the calculation ignores an overlooked risk: the cost of capital. Kalshi has raised approximately $65 million to date. At a $2 million annual lobbying burn rate (plus legal fees, compliance, and senior political hires), its cash runway for political operations is about 2-3 years. If the regulatory battle extends beyond 2027, the company will need a new round of financing at unfavorable terms.
During my 2017 ICO due diligence audits, I saw this pattern before. Projects that spent heavily on regulatory engineering often ran out of cash before the legal framework materialized. The collateral damage was their token price—but Kalshi has no token. Its valuation is entirely dependent on fee revenue. And fee revenue from sports contracts is notoriously seasonal and correlated with major events.
Internal documents from a competitor (obtained via FOIA) show that the CFTC’s Enforcement Division has opened 12 investigations into potential insider trading on prediction markets since 2023. Six of those involved employees of federally regulated exchanges. The agency is not just reacting to casino pressure—it sees a genuine enforcement gap.
Contrarian
The popular narrative is that prediction markets are fighting a noble battle against entrenched gambling interests. That the underdog will prevail because the technology is superior—on-chain settlement, censorship resistance, global liquidity.
I disagree. The data suggests the opposite.
The real threat to prediction markets is not regulation itself. It is the _cost of being regulated first_.
Kalshi is spending $1.8 million to be the first-mover in compliance. That money does not build better contracts, improve user experience, or attract liquidity. It is a defensive expenditure that generates negative ROI until the regulatory outcome is known. And if the outcome is unfavorable, the money is wasted.
Polymarket’s strategy is the inverse: spend nothing on compliance, accept the risk of enforcement. If enforcement comes, the cost of defense (legal fees, potential fines, forced shutdown) may far exceed Polymarket’s saved lobbying budget. The asymmetry is a gamble in itself.
The casino industry understands this dynamic. They are not trying to beat prediction markets on technology. They are trying to make regulation _so expensive_ that only a few players survive. And those survivors will be so depleted that they cannot compete for market share.
This is a textbook example of regulatory capture. The incumbents use the state to raise the cost of entry for challengers. The challengers respond by hiring the incumbents’ former employees. The system self-perpetuates.
But there is a blind spot in the casino strategy: they assume prediction markets operate on the same risk profile as traditional gambling. They do not.
Prediction markets are essentially information clearinghouses. The profit margin is structural: the platform always wins the fee, and the participants trade risk among themselves. Casinos, by contrast, carry the risk of the house edge. If a prediction market becomes large enough, it can offer better odds than a casino because it distributes risk globally.
The casino industry cannot match that cost structure without adopting the same technology. But if they adopt the technology, they become prediction markets. This is the contradiction they are trying to legislate away.
The contrarian trade: short the casino operators that are most exposed to sports betting, long the prediction market infrastructure (if it survives).
But this requires a catalyst. And the catalyst is the midterm elections.
Takeaway
If you are reading this in October 2025, the signal to watch is not Polymarket’s next feature release or Kalshi’s new contract type. It is the campaign contributions to members of the House Financial Services Committee.
By November 2026, we will know if prediction markets have a future in the United States. If the industry wins, the ETFs will follow. If they lose, the token prices of related projects will decouple from fundamentals entirely.
The alpha is not in the trade. It is in the lobbyist disclosure form. I don't trade on narratives—I trade on data. And the data says: whoever controls the CFTC nomination process controls the prediction market industry. Period.
Scarcity is an algorithm, not a belief system.
