Polymarket Crude Oil $100 [Live]: 89% Yes, 3 Weeks Left

Oil Is at $90 and the Market Says $100 by March 31 Is Almost Certain. Here Is Who Is Betting On It.

TL;DR: The Polymarket crude oil $100 market now prices a $100 CME front-month hit by March 31 at 0% ↓ probability. Six weeks ago, that same outcome sat at single-digit odds. U.S. and Israeli strikes on Iran changed everything. With – on this single price tier and $84.2M across the full oil series, the biggest question is no longer whether oil hits $100 — it is whether anything stops it before the deadline. Here is every known large position and what traders need to watch next.

The Market at a Glance

What Just Happened

On February 28, U.S. and Israeli forces confirmed strikes on Iranian targets. Oil markets responded immediately, pushing CME front-month crude above $90 for the first time since late 2023.

That single geopolitical event flipped the Polymarket crude oil $100 market from a long-shot bet into a near-certainty. Traders who bought Yes at single digits in the first days after launch collected the majority of the move. Anyone buying at current 0% ↓ prices is essentially renting certainty at a very high premium — not finding edge.

The odds have cooled slightly from their peak as ceasefire talks emerged in the Iran space. However, the market still prices $100 as a near-certainty, not a close call. That reflects where CME oil currently sits — just under $10 away from the resolution threshold with three weeks remaining on the clock.

Resolution Rules: What Traders Need to Know

This market resolves on CME data only. Spot price, Brent crude, or retail gasoline prices do not count. The specific contract is the front-month CL futures settlement price from CME Group.

Crucially, it resolves Yes if the CME front-month CL hits $100.00 or higher on any single trading day by March 31. It does not need to close at $100 — it only needs to touch $100 intraday on the CME settlement during any session between now and the final trading day of March.

That structure matters because even a brief spike during a news event — a fresh Iran escalation, a surprise OPEC cut, or a U.S. inventory miss — could trigger resolution before the deadline. Traders holding 100% ↑ shares do not get time to exit if oil spikes through $100 on a single bad headline.

Candidates & Analysis

Yes Side: Who Is Holding and What They Stand to Make

This market is still active and resolves March 31. All positions below show unrealized PnL only. No confirmed payouts exist yet.

GRIFONESPERANTO — Wallet: 0xb66d20bea38e293b44846c9bec5f208f98f6cb0d — Vol: –

The most visible Yes holder in the market’s comment section and public profile data. GRIFONESPERANTO holds multiple Yes shares on the $100 tier and appears across related price tiers in the same oil series. At current 0% ↓ prices, the Yes position sits deep in the money. If oil hits the CME threshold before March 31, the position settles at 100¢ and GRIFONESPERANTO collects the full payout.

Ralphi — Wallet: 0xf9696cc0b44224545e5a5a13aed16b8a65817ce8

Ralphi holds a large Yes position visible across both the $100 tier and the related $150 tier, with approximately 1,900 shares confirmed on the $150 level alone. The cross-tier exposure signals strong conviction — traders who load both the $100 and $150 tiers simultaneously believe the supply disruption story runs further than a single threshold. That is a classic escalation ladder structure in commodity prediction markets.

Early Buyer via Whale Alert — $42,500 Yes @63¢

An untagged wallet loaded $42,500 on Yes at approximately 63¢, flagged by on-chain order-book alerts roughly two days before current prices. At current 0% ↓ prices, this position carries an unrealized gain of roughly $40,000+ without a single resolution event. This entry point at 63¢ reflects the market before Iran ceasefire chatter pushed odds slightly back from their peak.

No Side: Who Is Underwater and by How Much

0xF9009e251a87B8B96Fb184591Da93546AF96cd0C — Vol: –

The most exposed public No holder. This wallet holds 3,725 No shares on the $100 tier at an average entry of 79.6¢. At current No prices of 100% ↑, this position is severely underwater — the wallet paid 79.6¢ for shares the market now values around 10¢. The unrealized loss runs deep into five figures. The only recovery scenario requires geopolitical de-escalation, a credible ceasefire deal, and CME front-month crude staying below $100 for every remaining session.

Other Public No Bets

No additional large No wallets surface in public alerts right now. However, the current 100% ↑ price means anyone who bought No above 20¢ is already looking at a 50%+ mark-to-market loss. On February 27, buying No on $100 oil seemed reasonable. One day later, the Iran strikes changed the entire supply picture.

Late No Buyers at High Prices

Scattered No buyers entered above 50¢ in the week following the strike news, likely betting that ceasefire talks would deflate the oil risk premium before March 31. Those positions now sit at 100% ↑. Anyone who paid 50¢ for No shares has absorbed an approximate 80% mark-to-market loss. At current prices, the rational move is to decide: hold and pray for a diplomatic breakthrough, or cut the loss now and recover 10–12 cents on the dollar.

What Flips This Market to No

Three scenarios could push the Polymarket crude oil $100 market back toward 100% ↑ before March 31:

A confirmed Iran ceasefire deal. If the U.S., Iran, and regional parties agree to a formal ceasefire that markets believe, the supply disruption premium in oil prices deflates. CME front-month crude would pull back, and the probability of touching $100 before March 31 drops sharply.

A surprise OPEC production increase. OPEC members responding to political pressure by flooding supply could cap price action below $100 before the deadline. However, this scenario looks unlikely given current cartel discipline and member incentives to keep prices elevated.

A broader risk-off event. A sharp equity selloff or dollar strengthening event could drag oil lower even without a direct supply change. A significant risk-off week could push CME crude below the range where $100 looks inevitable before March 31.

For context: the current Polymarket Iran ceasefire market prices a deal before June at around 70% No. That market and the oil $100 market run in opposite directions. A Yes on ceasefire is a No on oil $100 reaching the threshold.

Key Takeaways

At 0% ↓, there is almost no edge in buying Yes now. The traders who made money here bought at 5–30¢ in the first days after February 28. Current prices reflect near-certainty already. The risk-reward on a fresh Yes entry is poor.

The No side is a pure ceasefire bet. Buying No at 100% ↑ only pays off if Iran diplomacy moves fast and definitively enough to cool CME crude below $100 for every trading day through March 31. That is a specific, low-probability scenario.

The single-day resolution rule creates spike risk for No holders. Oil does not need to stay above $100 — one intraday breach on the CME settlement resolves this Yes. A single bad headline in the next three weeks ends the No case immediately.

Watch the Iran ceasefire market in parallel. The two markets move in opposite directions. Any meaningful move in the Iran ceasefire odds signals where the Polymarket crude oil $100 market is heading next.

CME data only means no Brent or spot price confusion. If Brent crude hits $100 but CME CL does not, this market does not resolve Yes. Track CME front-month CL specifically.
