Kalshi spent $990,000 in the first half of 2025. That is nearly equal to the company’s entire 2024 lobbying budget. For a startup still fighting for regulatory clarity, this number is not a line item. It is a survival signal.
We do not build in the dark; we audit the light. And the light reveals a fundamental shift: the battle for prediction markets has moved from code to Capitol Hill.
Context: The Regulatory Tipping Point
Kalshi and Polymarket represent two ends of the compliance spectrum. Kalshi is a CFTC-regulated exchange for event contracts, while Polymarket operates with a permissionless model using USDC on Polygon. Both have grown rapidly—Polymarket settled over $3 billion in volume during the 2024 election cycle—but their biggest growth obstacle is no longer liquidity or UI. It is legal definition.
Traditional casinos, backed by state compacts and decades of political donations, view prediction markets as a direct threat. They have the structural advantage of ingrained regulatory capture. The American Gaming Association spends millions annually lobbying to keep sports betting under state control. Prediction markets, which allow bets on anything from election outcomes to Fed rate decisions, challenge that monopoly.
Core: Quantifying the Political Arms Race
Let me be direct: I have audited dozens of protocol financials. When a company’s lobbying spend doubles in six months, it signals that the management perceives an existential threat—or a golden opportunity. In Kalshi’s case, it is both.
- Kalshi’s H1 2025 lobbying outlay ($990K) nearly matches its full-year 2024 spend ($1.1M). The company is now on pace to allocate over 50% of its operational cash flow to influence policy.
- Polymarket spent only $180K in the same period, roughly 18% of Kalshi’s level. This asymmetry reveals a strategic divergence: Kalshi is going all-in on regulatory capture; Polymarket is free-riding.
- The casino industry’s lobbying budget increased 30% in 2025, according to the article’s data. They are not sleeping.
The ledger remembers what the narrative forgets. The narrative says prediction markets are a technological revolution. The ledger says they are a political liability with a cost structure dominated by legal compliance.
But numbers alone miss the texture. Kalshi has hired former officials from the Obama and Biden administrations. It has onboarded Donald Trump Jr. as an advisor. This is not just lobbying; it is building a “revolving door” network to ensure access at the highest levels of the incoming administration (likely Republican-controlled after 2026 midterms). The company is placing a leveraged bet on political connectivity.
Polymarket’s lighter approach carries its own risk. If Kalshi fails and regulation turns hostile, Polymarket becomes the primary target—with no shield of political capital. Its permissionless model is both its strength (censorship resistance) and its Achilles’ heel (no friendly regulator to call).
Contrarian: The Overlooked Insider Threat
Most analysts focus on the lobbying war between Kalshi, Polymarket, and casinos. But the elephant in the room is the insider trading scandal that emerged in late 2025. Reports revealed that a trader with advance knowledge of a Trump rally used Polymarket to profit on a yes/no contract on rally attendance. This event crystallizes a genuine regulatory risk: if prediction markets become synonymous with insider trading, no amount of lobbying will save them.
Codifying the intangible: how art becomes asset. Prediction markets turn future events into tradable instruments. But when those instruments can be gamed by non-public information, they become liabilities. The CFTC could step in and ban certain event types—especially sports or political contracts—citing market integrity concerns. That would be a far more surgical strike than a blanket prohibition.
The contrarian angle? The insider trading problem may actually force faster regulatory clarity. Incumbents like Kalshi will push for strict KYC and surveillance mechanisms to differentiate themselves from “wild west” platforms. In the long run, a well-regulated prediction market is more defensible than one that tolerates insider activity.
Takeaway: The Next 18 Months Decide Everything
The 2026 midterm elections will act as a catalyst. If Republicans sweep Congress, Kalshi’s political capital (via Trump Jr. connections) pays off. If Democrats retain control, the casino lobby—historically Democratic-friendly—wins the day.
Investors should watch three signals: (1) Kalshi’s ability to raise new funding at a higher valuation (validating its strategy), (2) the introduction of any federal bill that explicitly exempts or bans event contracts, and (3) the outcome of the insider trading investigation. The ledger of political capital is being written now.
Will the next bull run belong to prediction markets, or will they be regulated into oblivion? The answer lies not in a GitHub repository, but in a Washington committee room. We do not build in the dark; we audit the light. And the light shows a war of attrition—where the cost of compliance may exceed the value of innovation.
