A $26.6B Trust Test Haunts Polymarket U.S. Comeback

$26.6 billion in combined trading volume across Polymarket and Kalshi is the scale behind the Polymarket U.S. comeback: this is no longer a niche crypto sideshow, it’s a fight over whether event markets can become a regulated consumer finance product in America.

Polymarket is preparing a U.S. marketing push built around influencers, sports partnerships, Major League Baseball, and media deals with outlets including CNBC and CNN, according to CoinDesk. The company’s real problem, though, isn’t awareness. It’s credibility after a four-year U.S. absence, a $1.4 million CFTC settlement, and fresh questions over marketing practices.

The Polymarket U.S. comeback is a trust campaign disguised as a marketing blitz

Polymarket wants policymakers, regulators, partners, and potential users to see a different company from the one pushed offshore in 2022. That requires more than TikTok reach and sports logos. It requires convincing the market that Polymarket U.S. is legally separate, operationally controlled, and safer than the international platform that became famous online.

The company’s own U.S. operations chief framed the challenge directly.

“I think having the international business being the bulk of the volume, it often sort of masks the progress we are making here in the U.S. to broaden Polymarket’s acceptance,” Lee said.

That quote matters because it reveals the split at the center of the relaunch. Polymarket’s international business still carries the brand’s energy and scale. The U.S. business needs the legitimacy.

XOOMAR analysis: The marketing blitz is best read as a compliance story with an advertising budget. Polymarket isn’t just buying attention. It’s trying to recast event trading as a mainstream, rules-based product before regulators, media partners, and skeptical users decide the old reputation still fits.

A $1.4 million CFTC settlement left a brand problem money can’t fix

Four years ago, Polymarket agreed to stop serving U.S. customers as part of a $1.4 million settlement with the Commodity Futures Trading Commission, which alleged the company offered unregistered event-based derivatives. That enforcement action turned access itself into a trust issue.

The problem didn’t end with the settlement. In late 2024, federal law enforcement officials raided CEO Shayne Coplan’s home as part of an investigation into whether Polymarket continued serving U.S. users despite the agreement. CoinDesk said at the time it confirmed U.S. residents were able to trade on the platform despite the agreement. Prosecutors and the CFTC later dropped the investigations without charges after a change in presidential administration.

That sequence gives critics a simple story: Polymarket left the U.S., Americans still found access, and enforcement questions followed. Polymarket now has to replace that story with a cleaner one.

Prediction markets are also easy targets because they combine finance, sports, politics, news, and internet virality. XOOMAR analysis: That mix makes classification hard and reputational risk high. A platform can regain legal access faster than it can regain institutional comfort.

For readers tracking the broader regulatory angle, XOOMAR’s related coverage on the CFTC Investigation Drags Polymarket Into Compliance Fight sits in the same trust-and-oversight lane.

The $26.6 billion volume figure explains why Polymarket is rushing back

The Associated Press reported that trading volume across Polymarket and Kalshi reached $26.6 billion, according to blockchain analytics firm Dune, up from $9.75 billion in October last year. About two-thirds of that activity is on Kalshi, which AP said dominates the U.S. market on the strength of sports wagering.

That scale explains the urgency. If event markets are becoming a larger consumer trading category, Polymarket can’t afford to remain known mainly as the offshore crypto-native venue.

The social metrics show another gap. CoinDesk reported Polymarket’s X account has 1.7 million followers and posts about current events several times a day. Kalshi has 431,400. Polymarket has the internet-native audience. Kalshi has the more established U.S. regulatory posture, having operated under CFTC supervision since 2020.

The business logic is clear. More users can improve market depth, pricing, and visibility. But there’s a catch. Spending heavily before trust is repaired can turn every ad, influencer post, and partnership into another compliance test.

Influencers, MLB, CNBC, and CNN raise the stakes for disclosures

Polymarket’s relaunch is already running into the exact issue that can damage a trust campaign: marketing transparency.

CoinDesk said the push follows a Wall Street Journal investigation alleging Polymarket used paid influencers to promote simulated trades and winnings on social media without adequate sponsorship disclosures. The company told the WSJ it was “committed to maintaining accurate, fair, and transparent markets.”

AP also reported that Polymarket hired social media influencers for viral marketing on TikTok and other platforms, signed deals with major sports teams and Major League Baseball, and partnered with news organizations including CNBC and CNN.

That combination is powerful but risky. Sports teams bring mainstream reach. News outlets bring credibility by association. Influencers bring distribution. If disclosures are weak, all three can backfire.

This is the same broad problem that hits trust-sensitive fintech and crypto figures when financial incentives aren’t clear to the audience. XOOMAR’s related piece on Undeclared Crypto Gifts Pull Nigel Farage into Trust Storm is useful context for how quickly disclosure issues can turn into reputation damage.

Polymarket U.S. has to look different from Polymarket International

AP reported that Polymarket U.S. operates through a more centralized structure regulated by the CFTC and funded with traditional U.S. dollars. Polymarket International is built on blockchain technology and requires users to trade with cryptocurrency.

That distinction is central to the company’s pitch. U.S. users may not see much difference beyond funding, AP reported, but the underlying structure matters. The U.S. version is expected to offer a narrower number of contracts and more regulation than the international platform.

Polymarket has also hired compliance, surveillance, and regulatory specialists. AP reported that Megan McGrath joined from Robinhood as chief compliance officer, while Dan Lee and Natalie Oblazny came from Coinbase. The company also hired former Department of Justice and FBI officials as head of enforcement and surveillance head.

Lee’s strongest line to AP was blunt:

“Trust is the product we are building here,” said Dan Lee, head of U.S. operations at Polymarket.

That’s the right message. The test is whether the operating model matches it.

Regulators, traders, media partners, and skeptics are not judging the same product

To traders, Polymarket’s appeal is speed. Real-money markets can move faster than pundit commentary or polling narratives. That’s the pitch AP described: real-time markets as a more accurate read on the future than traditional polling or punditry.

To regulators, the same speed can look like risk. Event contracts tied to politics, sports, news, or public outcomes invite hard questions about market integrity, consumer disclosures, manipulation, and jurisdiction. The source material doesn’t establish that these risks occurred on Polymarket U.S., but they are the obvious pressure points for any regulated event market.

Media partners have a different concern. If prediction market prices become part of election or breaking-news coverage, outlets need confidence that prices reflect real market activity and clear rules, not promotional theater.

Crypto skeptics will likely care less about the elegance of prediction markets and more about controls: surveillance, enforcement, user access, funding rails, disputes, and auditability. Polymarket’s hiring spree directly targets that concern.

The next test is whether compliance can scale as fast as the audience

The Polymarket U.S. comeback now rests on a narrow question: can the company keep the cultural momentum of its international brand while operating under the tighter rules of the U.S. market?

Evidence that would support the comeback thesis includes clean influencer disclosures, visible compliance controls, durable CFTC-supervised operations, and partnerships that survive scrutiny. Evidence that would weaken it includes more marketing controversies, blurred lines between U.S. and international activity, or renewed enforcement pressure.

If Polymarket earns trust, prediction markets could become a more visible layer in financial media, sports discourse, and political analysis. If the relaunch stumbles, the U.S. return may harden the opposite lesson: in event markets, liquidity gets attention, but compliance decides who gets to stay.
