Polymarket user wins $22,000 in KPMG earnings bet streak

Polymarket accounts won about $22,000 on earnings bets tied to KPMG-audited companies, Bubblemaps said. The 42-bet pattern drew scrutiny.

A 42-bet earnings pattern

The blockchain forensics firm said it found trades across 18 companies with KPMG as auditor, including Wells Fargo, the Home Depot and DoorDash. The wagers began in November last year and ran for several months, giving the activity a longer footprint than a single earnings cycle.

Bubblemaps described 19 Polymarket accounts that it said were connected through transfers of digital funds. The firm said those flows formed a transaction web that could indicate one person or a coordinated group, though it said the analysis was not proof of insider trading.

The contracts were structured as binary bets on whether reported earnings would come in above analyst expectations. Of 42 wagers tied to KPMG audit clients, 41 were profitable, a 98% win rate compared with one losing bet, according to Bubblemaps.

General Mills trade stands out

One example came on March 18, when General Mills reported weaker earnings that included a decline in snack sales. Its shares fell 3% that day following the release, while a Polymarket account called greatfan1983 made $654.40 from the miss, Bubblemaps said.

Greatfan1983 was among the 19 accounts Bubblemaps linked in its review. The firm said the account mainly placed wagers on companies that used KPMG as auditor, a concentration that made the trading pattern more visible on-chain.

The open question is whether the same user is connected to a KPMG employee reportedly under federal investigation over alleged Polymarket trading. Bubblemaps said it could not establish that link, and its findings should be read as blockchain pattern analysis rather than a legal conclusion.

Prediction markets face probes

The case lands in a market where event contracts have moved from niche crypto-adjacent products into a wider political and corporate information business. Authorities in the US and Israel have charged military personnel with using restricted information for Polymarket trades, while officials have accused other traders of relying on sensitive corporate data or knowledge of President Trump’s planned speeches.

KPMG pushed back against any use of client information for trading. A spokesman said the firm has “zero tolerance for violations of our well-understood and clear policies against trading on nonpublic client information, including on prediction markets.”

If Bubblemaps’s account-linking holds under official review, Polymarket would face pressure to show that its market-surveillance tools can detect clustered accounts before payouts become public case studies. If the pattern cannot be tied to nonpublic information, the episode still leaves prediction-market operators with a harder compliance problem: high win rates may be legal, but they can look indistinguishable from information leakage until investigators reconstruct the trade path.
