The Lobbying Report landed on my desk like a poorly audited smart contract—full of hidden variables and unaccounted-for risks. Kalshi, the CFTC-regulated prediction market, spent $990,000 on lobbying in the first half of 2025, nearly matching its entire 2024 expenditure of $1.07 million. Polymarket, its decentralized counterpart, spent a mere $180,000—less than 20% of Kalshi’s outlay. The disparity isn't a margin of error; it's a structural fracture exposing how two platforms are placing fundamentally different bets on the same existential question: Will Washington legitimize or kill prediction markets?
This isn't a story about technology. It's about the moment a nascent industry realizes that its code runs on permission, not just proofs. And permission, in the United States, is bought with relationships, not gas fees. The numbers are stark, but they only hint at the deeper asymmetry: the traditional casino industry, which views prediction markets as direct competition, increased its own lobbying by 30% to $77 million in 2025. The incumbents have a structural advantage, as former Representative Patrick McHenry bluntly noted. The prediction market challengers are trying to outspend a century of entrenched political power with pocket change.
Volatility is just unaccounted-for variables. In this case, the variable is regulatory destiny.
Context: The Two Paths to Legitimacy
Prediction markets occupy a peculiar regulatory niche. They look like gambling—users bet money on the outcome of events, from elections to sports scores—but their proponents argue they are instruments of price discovery and risk hedging. In 2021, Kalshi won approval from the Commodity Futures Trading Commission (CFTC) to operate as a designated contract market for event contracts, effectively becoming a regulated futures exchange for binary outcomes. Polymarket, built on Ethereum and running on Polygon, takes a permissionless approach: users trade via smart contracts using USDC, with no central authority to censor markets. But that freedom comes with costs—Polymarket has faced CFTC scrutiny and a $1.4 million fine in 2022 for failing to register as a swap execution facility.
Both platforms are now in the crosshairs of a broader legislative battle. The American Gaming Association, representing casinos, has lobbied hard to classify sports-related event contracts as illegal gambling under state laws, arguing they siphon revenue from regulated sportsbooks. Meanwhile, a series of insider trading scandals—most notably a Polymarket user who allegedly traded on non-public information about a merger by creating multiple accounts—has handed regulators and legislators ammunition to paint prediction markets as breeding grounds for fraud.
Core: Dissecting the Lobbying Arms Race
Let's treat this as a forensic audit of political capital. The data points are clear:
- Kalshi’s Strategy: Spend heavily on influence. Hire former Obama and Biden administration officials. Bring on Eric Trump (Donald Trump’s son) as an advisor. Target both parties. Their logic: By spending $1.8 million in a single half-year, they are buying a seat at the table where the rules are written. If they fail, the entire regulatory framework they've built under the CFTC could collapse. This is a high-leverage, all-in bet.
- Polymarket’s Strategy: Spend lightly. Rely on the argument that decentralized protocols are inherently outside CFTC jurisdiction because there is no intermediary to register. Let Kalshi fight the political war, and free-ride on any favorable outcomes. Their $180,000 is a token effort—enough to maintain a lobbyist on retainer, but not enough to shift votes.
- The Incumbent Response: The casino industry, with $77 million in lobbying, doesn't need to create new regulatory barriers—it needs to preserve existing ones. State-level gambling laws already ban most event wagering outside licensed sportsbooks. The threat is that Congress could preempt state laws via a federal framework that explicitly allows prediction markets under CFTC oversight, or conversely, that it could ban them outright. The casino lobby's 30% spending increase is a defensive maneuver: they fear a pro-prediction market bill could erode their monopoly.
The core insight here is not about who spends more. It's about who has the better structural position. The casino industry is not just spending more; it has a century of political relationships, PAC contributions, and a web of state-level regulations that would be extremely costly to unwind. Kalshi's $1.8 million is a rounding error compared to the casino industry's cumulative investment. Trust is a vulnerability vector. The casino industry's trust was built over generations; prediction markets are trying to buy it in quarters.
The Insider Trading Variable
The Polymarket insider trading incident—where a user allegedly exploited non-public merger information by opening multiple accounts, violating the platform's terms but not its code—highlights a critical blind spot. The platform's decentralized architecture makes it resilient to censorship but weak against KYC/AML enforcement. Even as Polymarket tightened rules, the internal controls failed to detect the pattern until after the fact. This event has already triggered CFTC inquiries and could be the smoking gun that convinces Congress that prediction markets require tight oversight.
The code speaks louder than the whitepaper. And in this case, the code says: “I have no identity verification built in.” That's a feature for cypherpunks but a liability for regulators. Kalshi, with its centralized KYC and cleared-only model, has a regulatory defense that Polymarket lacks. But Kalshi's centralized model also exposes it to single points of failure—if the CFTC changes its interpretation, Kalshi loses its license. Polymarket, by contrast, could survive a ban on its frontend by retreating to fully decentralized interfaces like Augur or Omen, though at the cost of user experience.
Contrarian: What the Bulls Got Right
Before dismissing the prediction market sector as a doomed regulatory play, consider what the bulls see that critics miss. First, prediction market volumes are growing organically, driven by retail interest in elections and sports. Data from Dune Analytics shows Polymarket's monthly volume exceeding $2 billion in March 2025, up 15x year-over-year. This isn't just hype; it's genuine demand. Second, the political landscape may shift. If the Republican Party wins a clean sweep in the 2026 midterms, Kalshi's relationship with the Trump family could become a massive asset. Eric Trump's role as an advisor is not just for show—it's a direct line to a potential administration that views regulation as a barrier to innovation.
Third, there is a credible legal argument that prediction markets are protected by the First Amendment as a form of information collection and expression. The Cato Institute and other libertarian groups have championed this view. If the Supreme Court ever takes up a case on event contracts, the outcome could fundamentally weaken the government's ability to ban them. The bulls bet on inertia: the longer Kalshi operates without major scandal, the more entrenched it becomes, making it politically costly to shut down.
But even these arguments are cold comfort. Logic does not bleed, but it does break. The bullish narrative ignores the fact that regulatory victories are rarely clean. Even if prediction markets survive, they will be saddled with compliance costs so high that only well-funded entities like Kalshi can afford them, effectively creating a barrier to entry that kills the decentralized ethos Polymarket represents.
Takeaway: The Verdict Is Not in the Code
The lobbying numbers are not just data points; they are signatures of desperation. When a startup spends six months of its burn on political influence, it signals that it believes its survival depends more on a few dozen congressional aides than on its product. That is a fragile foundation. The ultimate outcome will be determined not by technical innovation but by a single question: Does the casino industry's entrenched political machine outweigh the prediction market's narrative of democratized finance?
My bet, based on 24 years of watching blockchain projects fail because they ignored political reality, is that the incumbents will win in the short term—but that the idea of prediction markets will outlive any regulatory crackdown. The real question is which platform will survive to serve that future. The code can be rewritten, but trust cannot be patched. Kalshi is spending to build trust. Polymarket is spending to survive. Neither strategy is a sure thing.
As the CFTC and Congress debate the future of event contracts, remember: Aesthetics are often exploits in waiting. The glossy lobbying reports and hired advisors are just a prettier version of a smart contract with an admin backdoor. The only difference is that this backdoor opens not to a wallet, but to a senator's office. And the key is held by the highest bidder.
