The 30 most profitable political traders on Polymarket have $229K betting on Democratic Senate control, compared with just $59K on Republicans.
That’s nearly a 4-to-1 advantage for Democrats, which looks pretty convincing with Polymarket pricing Democratic control at 73.5%.
There’s just one catch. Of that $229K, a single wallet accounts for $145K. Remove it, and the midterm elections picture changes considerably.
Senate race driven by one trader at Polymarket
PredictionPro tracks Polymarket’s most profitable political wallets and combines their positions across related markets. That matters because traders can bet on Democratic Senate control in more than one way, including buying Democratic Yes or Republican No.
Most of the Democratic money is actually sitting on Republican No, which trades at 72.5 cents compared with 73.5 cents for Democratic Yes. Looking at just the Democratic listing would make the group appear net short by $26K, even though its combined positioning strongly favors Democrats.
The biggest player is wallet 0x4488…e319, ranked No. 13 among political traders with $1 million in profit and a 77% win rate across 129 closed positions.
This wallet has built a substantial election portfolio:
- $145K on Republican Senate No, entered at 70.7 cents.
- $143K on Democrats sweeping both chambers, entered at 68.6 cents.
- $151K across the two Texas Senate listings.
Remove this prediction market trader, and the remaining Senate positions fall to $84K Democratic versus $59K Republican. That’s a 59/41 split, considerably less bullish than the market’s 73.5% Democratic price.
Not everyone is buying the Democratic wave, either. Wallet 0x011f…1122, ranked No. 23 with $664K in political profit, is positioned for Republicans to retain the Senate while Democrats take the House. It’s also betting against Democrats in Maine and Michigan.
Those four positions are currently down about $21K as markets have moved in the opposite direction.

Smart money agrees on Texas Senate race
Texas tells a much different story.
Across its Senate markets, the top political wallets hold $365K on Democrats against just $4.9K on Republicans, making it the largest individual race position in the group.
More importantly, that conviction extends well beyond one trader. Remove wallet 0x4488 and Democrats still lead $214K to $5K. Nine wallets are involved in each of the two Texas listings, including the No. 25 wallet, 0x614d…1546, which holds $121K across both.
The market has been moving their way. Republican odds have dropped from 35.5% on October 26 to 24.5% this morning, with $1.08 million traded over the past 24 hours.
PredictionPro’s broader Smart Money tool, which tracks a separate group of top wallets ranked across all trading categories, tells a similar story. Every tier favors Democrats, producing an implied probability of 86.7% compared with the market’s 75.5%.
That’s an 11.2-point difference between what the tool suggests and what traders are currently paying.
Unlike Senate control, Texas looks like genuine agreement across multiple profitable wallets rather than one trader making an oversized bet.
The seven-state sweep is a bet on a Democratic wave
Some traders are going considerably further than simply picking Democrats to win the Senate.
Four of the top political wallets hold $120K on Republicans losing all seven of Alaska, Iowa, Kansas, Maine, Michigan, Ohio and Texas. None of the tracked wallets is betting against that outcome.
The contract has jumped from 18 cents on October 28 to 31.5 cents today.
What’s notable is how much more expensive that bet is than the individual races would suggest.
If the seven outcomes were completely independent, multiplying their Democratic win probabilities together would produce just a 7.3% chance of a clean sweep. Polymarket is charging 31.5%.
That difference comes down to correlation. Traders aren’t treating these as seven unrelated races. They’re betting that if the national environment is strong enough for Democrats to win one difficult state, several others are likely to follow.
Iowa is the biggest obstacle, with Democrats priced at just 49.5%. At current prices, the sweep market effectively implies that if Democrats win Iowa, there’s roughly a 64% chance they also take the other six states.
The tracked wallets lean Democratic in Iowa as well, $22.6K to $2.6K, although the positions are relatively small.
The largest sweep holder, wallet 0x6139…a99e, has $74K on the seven-state outcome and another $38K on Republicans finishing with 47 or fewer Senate seats. Its historical win rate is only 40%, suggesting a strategy built around larger payoffs rather than consistently winning a high percentage of trades.
Where the smart money disagrees
The Democratic positioning looks overwhelming in Texas, but several other races tell a more complicated story.
Maine is the clearest disagreement. PredictionPro’s broader Smart Money group is unanimously Democratic, while the politics-only cohort actually leans 64% Republican, with $42K against Democrats and $24K supporting them. That Republican group includes the No. 2, No. 4 and No. 8 ranked political wallets.
Their individual positions are relatively small, however, generally around $6K to $7K. Maine’s Democratic odds have also climbed from 59.5% to 74.5% over the past week, putting those bets on the wrong side of the recent move.
Michigan is much closer than its market price suggests. Democrats trade at 80.5%, but the cohort holds $68.5K Democratic against $60K Republican. One tracked wallet sold $16.7K of Republican Yes at 25 cents last night, suggesting at least some traders are abandoning that side.
Alaska is another concentrated bet. Democrats are priced at 73.5%, with wallet 0x000d…758e holding nearly $70K on Mary Peltola. Just $9K is positioned against her across five other wallets. That leading wallet ranks No. 10 in politics profit and has a 77% historical win rate.
South Carolina is the exception. The cohort is 84% Republican, although $61K of that positioning comes from our familiar wallet 0x4488. That trader bought Annie Andrews No at 75.5 cents, and the contract has since fallen to 68.5 cents.
The takeaway is that even highly profitable traders don’t agree on every race, and some of the largest positions are already underwater.
The bigger picture: traders are positioned for a blue wave
Across the broader election markets, PredictionPro’s top political wallets are clearly positioned for a strong Democratic night.
Democratic House control, already priced at 94.5%, has $386K of cohort positions on Yes against just $11K on No. The Democratic sweep of both chambers has another $275K supporting it, compared with $11K against.
And outside South Carolina, there isn’t a single state where the cohort favors Republicans by more than a few thousand dollars.
But the strength of that signal depends on where you look.
Texas has broad agreement across multiple profitable traders. Senate control looks much less convincing once its biggest holder is removed. Maine has two groups of successful wallets taking opposite sides, while Alaska is dominated by one large position.
There’s also the question of how much of this bullish outlook is already reflected in prices. Kansas has moved 24 points toward Democrats, Maine 15 and Texas 11 over the past week. Anyone buying now is paying considerably more than traders who built positions earlier.
With Election Day tomorrow, November 3, the opportunity isn’t simply identifying which party smart money likes. It’s figuring out where its conviction is strongest and whether the current price still leaves enough upside.
The trade: Texas Democrats at 75.5 cents
Texas is my favorite way to express the Democratic wave thesis.
At 75.5 cents, it offers broader agreement across profitable wallets than the Senate control market. The contract has a roughly 1-cent spread and $1.6 million in resting liquidity, making it relatively easy to enter and exit compared with thinner state markets.
PredictionPro’s broader Smart Money tool implies an 86.7% Democratic probability. Even splitting the difference between that estimate and Polymarket’s 75.5% price produces a fair value around 81 cents, leaving approximately 4.5 points of potential edge after accounting for the spread.
For additional upside, the seven-state Democratic sweep at 31.5 cents offers a more aggressive way to bet on election night. It has roughly $1.4 million in liquidity, but all seven races must go Democratic for the contract to pay. I’d treat it as a small addition to Texas rather than the primary position.
