TL;DR
- Senator Chris Murphy claims that insiders close to the White House earned over $1 million from prediction market contracts related to the US military attack on Iran
- Murphy plans legislation that would ban betting on government actions in prediction markets
- The case highlights the regulatory debate surrounding decentralized prediction markets like Polymarket
- Market experts argue that such markets provide valuable information aggregation — but the insider risk is real
Murphy Targets White House Circles
Senator Chris Murphy of Connecticut has strongly criticized what he describes as blatant insider trading on prediction markets. According to The Block, Murphy claims that individuals with ties to the White House allegedly positioned themselves on contracts related to a US military strike against Iran — and that these positions yielded over one million dollars in returns.
Murphy has not publicly disclosed the names of the alleged insiders, and the claims are currently unverified. 24Krypto emphasizes that the accusations are currently political claims from a single senator, not documented findings from an independent investigation.
The claims are currently unverified — but political dynamite at a time when prediction markets are growing explosively
Legislation in the Pipeline
In response to what he considers a serious conflict of interest, Murphy plans to introduce legislation that would make it illegal to place bets on government actions through prediction markets. This would effectively mean a ban on markets that price in the probability of military operations, legislative acts, and other public decisions.
The proposal comes at a time when the prediction market sector is experiencing strong growth. According to industry data, the decentralized prediction market segment was valued at $1.4 billion in 2024 and is expected to reach $95.5 billion by 2035 — an annual growth rate of nearly 47 percent.
Polymarket in the Storm — Again
This case is a new chapter in a long history of regulatory pressure against leading players in the sector. Polymarket, considered the world's largest decentralized prediction market and operating on the Polygon blockchain, was fined $1.4 million by the US financial regulator CFTC in January 2022 and ordered to cease services for US users. Nevertheless, the company is experiencing strong growth — with a private market valuation of $9 billion and an investment from Intercontinental Exchange (ICE) of $2 billion in October 2025.
Murphy's bill, if passed, would potentially affect the entire category of political and military markets — not just Polymarket, but also decentralized competitors like Augur and Gnosis-based platforms.
Industry Defenders: Markets Uncover Truth
Proponents of prediction markets reject that a ban is the solution. They point out that such markets have consistently proven more accurate than opinion polls on political outcomes. Among other things, research showed that prediction markets provided more precise estimates than 74 percent of opinion polls for the five US presidential elections between 1988 and 2004. During the 2024 presidential election, Polymarket was highlighted as particularly accurate in states where polls failed.
Vitalik Buterin, co-founder of Ethereum, has referred to prediction markets as the very core of what he calls “information finance” — systems that provide financial incentives to produce reliable knowledge.
Insider Risk is Real — and Difficult to Solve
It is nevertheless difficult to dismiss Murphy's core point: if actors with access to non-public government information can trade freely on prediction markets, there is an obvious and serious market distortion. The issue is in principle identical to insider trading in stock markets — and regulated accordingly in traditional finance.
Decentralized prediction markets, however, are designed to resist censorship and centralized control, which makes enforcement challenging. Smart contracts execute trades automatically, and pseudonymous wallets make it difficult to track who actually profited from such positions.
What Happens Next?
Murphy's bill is currently in the proposal stage, and it is unclear whether it will receive sufficient support in the Senate. Republicans have recently signaled a more crypto-friendly stance, and the political climate in Washington is not necessarily favorable for new restrictions on decentralized financial markets.
However, the case will likely contribute to increased pressure on the CFTC and other regulatory bodies to clarify the rules for prediction markets with political content — something the industry itself has called for for years.
With Bitcoin trading around $73,000 and a fear-and-greed index at 22 out of 100, the mood in the crypto market is cautious. News of potential tightening of regulation is unlikely to boost risk appetite in the short term.
