While the rule explicitly specifies LM Arena as the source, there are two significant risk points: 1. The definition of 'second best' can be complicated by ties; although the rule mentions alphabetical resolution, this adds complexity. 2. Model attribution issues, for example, if models from xAI or DeepSeek are renamed or merged, could spark disputes. Additionally, the 'Second Best' spot is highly volatile, making the exact moment of settlement crucial.

Since insiders (researchers, engineers at AI labs) may know the performance benchmarks (SOTA levels) of upcoming models in advance, there is significant information asymmetry. This event correlates directly with the stock prices of AI giants. If a model from Google or OpenAI unexpectedly underperforms or excels, it directly impacts market confidence in their AI competitiveness, affecting GOOGL or MSFT prices. Hedging is significant.

2026-04-28 to 2026-05-02, Google's price rebounded strongly from 13c to 24.5c, as market expectations warmed up regarding its model's chances of securing second place. 2026-04-26 to 2026-05-02, OpenAI's price steadily declined from 14.9c to 9.05c, reflecting growing market belief that its latest model will comfortably secure the #1 spot, thus lowering the likelihood of it resolving as #2. 2026-04-22 to 2026-04-25, Google's price dropped from 24.5c to 12c, as market confidence in its next-generation models surpassing Anthropic or OpenAI by the end of June significantly weakened. 2026-04-19 to 2026-04-25, OpenAI's price steadily climbed from 9.15c to 22.35c, reflecting market sentiment that amid intensified competition, some of OpenAI's flagship models might settle in the second position. 2026-04-16 to 2026-04-18, Anthropic's price surged from 45.5c to 57c, as market confidence significantly increased regarding its ability to maintain or capture the second spot on the LMSYS leaderboard. 2026-03-29 to 2026-04-04, OpenAI's price steadily declined from 18c to 7.5c, reflecting market expectations that its next-generation model had firmly secured the #1 spot on the leaderboard, thereby reducing the probability of it resolving as #2. 2026-03-25 to 2026-03-28, Google's price fell from 33.5c to 21c, likely because the market lost confidence in Google's ability to release a product that surpasses new models from OpenAI and Anthropic in the short term. 2026-03-25 to 2026-03-28, Anthropic's price rose from 35c to 42.5c, due to the strong performance of its recent models, leading the market to expect a high probability of it securing a top-two spot.

The Bank of England's rate decision directly impacts the valuation of the British Pound and liquidity expectations for UK equities. A surprise hike or cut will immediately trigger significant tradable movements in the GBP/USD exchange rate and the FTSE 100 index. Additionally, because the Pound is a key component of the US Dollar Index, DXY will also experience some spillover effects.

2026-04-27 to 2026-04-28, the price of the 'No change' option plummeted from 70.5c to 42.5c, while the '25 bps increase' option surged from 27c to 49.5c. This sharp volatility reflects a sudden shock from unexpectedly strong macroeconomic data or hawkish central bank rhetoric, causing rate hike expectations to briefly overtake expectations of a hold. Over the following days, 'No change' expectations rapidly recovered to around 66.5c, while hike expectations retreated to roughly 28.5c. 2026-04-22 to 2026-04-23, the price of the 'No change' option plunged from 78c to 55c, while the '25 bps increase' option surged from 21.5c to 37c, reflecting a sudden spike in rate hike concerns influenced by hawkish macroeconomic data or official statements during this window, though expectations partially retraced in the following days. 2026-04-07 to 2026-04-08, the price of the '25 bps increase' option surged from 33.5c to 44c, reflecting rising market expectations for a rate hike due to persistent inflation concerns or recent macroeconomic data releases.

Predicting reality TV show winners is fairly standard in prediction markets, but a specific regional edition like Big Brother Argentina remains a moderately niche entertainment topic requiring local cultural context for the average global trader.

Between April 28, 2026, and April 29, 2026, the price of Juan "Juanicar" Caruso surged from 34c to 50c, Jennifer "Pincoya" Galvarini surged from 35.5c to 50c, and Daniela "Dani" de Lucía and Lola Tomaszewski surged from 40c to 50c. This was caused by low market liquidity and AMM mechanisms pulling prices back to a default 50c level. No other price movements exceeding 10c were observed in the last 3 days.

Between April 28, 2026 and April 29, 2026, Brendan Allen's Yes price surged from 37.5c to 49.5c, with other options also approaching 50c. This exacerbates the extremely irrational phenomenon where cumulative probabilities far exceed 100%, likely driven by extreme illiquidity or blind buying. Between April 12, 2026 and April 13, 2026, the Yes prices for all listed options spiked significantly (e.g., Brendan Allen from 28.5c to 45c, Anthony Hernandez from 29.5c to 51.5c, Dricus Du Plessis from 21c to 46c). This is highly irrational as the options are mutually exclusive and their probabilities cannot simultaneously surge by such margins. This is likely due to extremely poor market liquidity or irrational trading behavior causing severe mispricing.

This is a statistic-specific question for the crypto industry. While not as mainstream as general elections or sports, analyzing the 'survival rate and explosiveness of new coins' is a relatively routine market cycle topic for crypto natives. It's not entirely exotic but falls under niche sector data prediction.

April 28, 2026 - April 29, 2026, the price of the '>10' option surged from 24.5c to 51c, and '>12' surged from 22c to 40c, driven by a recent concentrated explosion of new 2026 tokens, causing over-optimism about the number of year-end survivors with high market caps and triggering short-term speculation. April 20, 2026 - April 22, 2026, the price of the '>6' option plummeted from 54c to 41c, as the market reassessed the actual year-end survival rate of most new 2026 tokens after a short-term issuance frenzy, causing mid-tier thresholds to revert to the mean. April 12, 2026 - April 15, 2026, the price of the '>4' option surged from 54c to 66c, driven by the strong performance of several newly launched 2026 tokens that rapidly climbed the market cap rankings, boosting confidence in reaching this baseline threshold. March 3, 2026 - March 17, 2026, the price of the '>8' option plummeted from 46.5c to 33c as the market corrected the speculative surge seen in early March. Lacking sustained macro catalysts, traders reassessed the extreme difficulty of having 'more than 8 top-100 projects from the same vintage', causing prices to revert to the mean. March 1, 2026 - March 2, 2026, the price of the '>8' option surged from 32c to 46.5c, likely driven by short-term liquidity flows or over-optimism sparked by breakouts in specific sectors like Meme or AI.

This event is directly linked to UK monetary policy expectations. Inflation data for 2026 will dictate the Bank of England's (BoE) interest rate path for that year. Significantly higher-than-expected inflation (e.g., >4.5%) would boost the British Pound (GBP) and UK Gilt yields, while potentially weighing on UK equities (FTSE) due to tightening fears. As core macro data for a major economy, it has clear hedging value.

Apr 24, 2026 - Apr 26, 2026, the price of '<1.0%' surged from 0.25c to 11.25c, likely driven by short-term speculative buying on economic slowdown concerns. Mar 6, 2026 - Mar 10, 2026, the price of '2.5–2.9%' crashed from 36c to 21.5c, as OBR officials warned on Mar 10 that the Middle East conflict could push inflation to 'around 3%' by year-end 2026, shifting expectations out of this moderate band into higher risk territories. Mar 6, 2026 - Mar 9, 2026, the price of '1.0–1.4%' dropped from 37c to 28c, a partial correction of its extreme overvaluation, though it remains surprisingly high. Feb 9, 2026 - Feb 11, 2026, the price of '<1.0%' crashed from 30.5c to 7.5c as the market capitulated to the Bank of England's Feb 5 report anchoring forecasts at 2%.

The primary trap is the condition that if Fuse does not launch a token by the end of 2027, all options resolve to 'No', exposing bettors to project delay/failure risks. Furthermore, Fully Diluted Valuation (FDV) calculations rely on the total token supply, which can sometimes be opaque or disputed during the initial stages of a token launch.

April 28, 2026 - May 1, 2026, prices for several options like $1B, $3B, and $4B fluctuated wildly. The 'Yes' price for $3B surged from 26c to 49c, $1B from 23c to 39.5c, and $4B from 23.5c to 35.5c. The reason is extremely poor market depth, where tiny speculative buys triggered significant price jumps and severe probability inversions. April 14, 2026 - April 16, 2026, the prices of the $4B and $7B options experienced dramatic fluctuations exceeding 10c. The 'Yes' price for $4B dropped from 27.5c to 16.5c before rebounding to 25c, while the 'Yes' price for $7B surged from 9c to 19.5c. The reason is extremely low liquidity, where small orders can significantly alter market pricing and expose obvious mispricing. April 10, 2026 - April 13, 2026, the market remained relatively stable under low liquidity, with no price movements exceeding 10c observed.

This is a typical celebrity gossip market. While not as absurd as 'Jesus Resurrection', it is a niche topic for those focused on macro or hard finance, falling squarely into entertainment and fan economy domains.

Apr 25, 2026 - Apr 26, 2026, Option_'Yes' price spiked from 18.5c to 53c, primarily because a new wave of intense pregnancy speculation erupted on social media and in tabloids (fueled by over-analysis of TikTok videos and gossip about family pressure), drawing massive speculative capital despite the lack of official confirmation. Mar 21, 2026 - Mar 26, 2026, Option_'Yes' price dropped from 39c to 26.5c, a decrease of more than 10c, primarily because the passage of time without new pregnancy evidence or media hype led early speculative capital to gradually take profits or cut losses. Mar 1, 2026 - Mar 5, 2026, Option_'Yes' price slowly drifted down from 20c to the 17.5c-18c range due to an information vacuum. Since the last media hype cycle (early Feb) faded, the lack of new catalysts caused bullish patience to wear thin, leading to a slow capital outflow. Feb 9, 2026 - Feb 11, 2026, Option_'Yes' price drifted down from 23c to 20c, likely due to the absence of a speculated announcement during the Feb 8 Super Bowl, causing short-term speculators to exit despite unchanged fundamentals. Feb 5, 2026 - Feb 7, 2026, The market faced conflicting sentiment shocks. Viral cheating rumors on Feb 5 initially suppressed prices, but subsequent Feb 7 media reports claiming Kylie is in 'nesting mode' and an announcement is 'imminent' provided support, causing price consolidation.

There is a significant divergence between the current prediction market price (implying a 53% probability) and mainstream media consensus. Mainstream entertainment outlets and official representatives have not confirmed any pregnancy, and previous rumors of a similar nature have been explicitly debunked. However, the market is currently pricing this at a better-than-coin-flip probability (>50%), indicating that it is heavily driven by social media sentiment and unverified gossip rather than the credible announcements required for market resolution.

This is a relatively niche policy prediction. While AI energy consumption is a hot topic, a full 'moratorium' is an extreme policy measure, not the standard path of discourse (like carbon taxes or efficiency standards). It sits on the border between legitimate concern and extreme hypothetical policy.

If a bill passing a moratorium on AI data center construction is enacted, it would be a devastating blow to the AI hardware supply chain (Nvidia, AMD) and cloud giants (Microsoft, Amazon, Google). It implies the physical path for AI compute expansion is severed, leading to a cliff-edge drop in demand for AI chips. Companies like Nvidia, whose core business is data centers, would likely face an extreme stock crash (Score 5). The Nasdaq 100 would also suffer significantly. This is a highly destructive 'black swan' scenario.

April 22, 2026 - April 26, 2026, Option_'Yes' price surged from 81c to 98.65c. This was driven by the Maine legislature passing a statewide AI data center moratorium bill (LD 307), which caused blind optimism, with most traders failing to digest the news of the governor's veto on April 24. April 9, 2026 - April 12, 2026, Option_'Yes' price surged from 33.5c to 39.5c, as some investors continued to bet that local restrictions might trigger federal follow-up or misjudged the rules regarding bans anywhere in the US. February 11, 2026 - March 10, 2026, Option_'Yes' price drifted down from 35.5c to 24.5c, as the market digested the news of NY Senate Bill S9144, realizing a state-level proposal is unlikely to translate into federal law given the Administration's pro-AI stance, causing panic to subside. February 9, 2026 - February 10, 2026, Option_'Yes' price surged from 31c to 36.5c, driven by the introduction of a NY bill to pause AI data center approvals, triggering fears of a domino effect or rule ambiguity (mistaking state law for a valid trigger).

There is a severe divergence. The Polymarket price for Yes is near 96c, implying an almost certain enactment of a moratorium. However, mainstream media and official records confirm that the only bill to pass a state legislature (Maine's LD 307) was vetoed by the governor on April 24 [9] and did not become law. Furthermore, the federal government is aggressively pushing deregulation to accelerate AI data center construction [7]. The market price is entirely divorced from current political and legislative realities.

This is a highly niche and conditional political market. It speculates not just on an election winner, but on an election that is itself contingent on the outcome of another event (the Presidential election). For a global audience, a by-election in Galway West is extremely obscure.

April 27, 2026 - April 30, 2026, due to indiscriminate speculative capital inflows, multiple candidates (e.g., Seán Kyne, Míde Nic Fhionnlaoich, Niall Murphy) saw their prices abnormally surge by 10c to 23c, pushing the total implied probability sum well over 100% and reflecting extreme market irrationality. April 13, 2026 - April 15, 2026, Noel Thomas's price dropped from 70.5c to 56c as the market began to correct his overvaluation following a previous irrational surge. April 13, 2026 - April 15, 2026, Mark Lohan's price rose from 3.7c to 9.45c as the market re-evaluated his potential as a left-wing candidate to contest the vacant seat. April 14, 2026 - April 15, 2026, Helen Ogbu's price surged from 1c to 8.35c, likely due to favorable polling or electoral analysis prompting capital inflows. March 30, 2026 - March 31, 2026, Noel Thomas's price plunged from 51c to 38c as the market initiated a belated correction on his extreme overvaluation, increasing selling pressure. March 29, 2026 - March 30, 2026, Niall Murphy's price surged from 3.75c to 20.6c due to speculative retail capital flowing into low-priced options searching for unpriced dark horses. March 28, 2026 - March 30, 2026, Seán Kyne's price surged from 7c to 21.5c (and further to 25.5c) as the market corrected its massive historical undervaluation of the strong Fine Gael candidate. March 12, 2026 - March 15, 2026, Sheila Garrity's price rose from 11c to 16.3c as the market re-evaluated her potential to inherit Catherine Connolly's vote base. February 24, 2026 - February 26, 2026, Noel Thomas's price dropped from 52c to 41c, and Seán Kyne from 50c to 38c, serving as a correction from an earlier period of extreme overvaluation (aggregate sum > 400%).

There is a severe logical divergence in the market. Since this is a single-seat by-election with only one possible winner, the sum of all candidates' win probabilities must mathematically equal exactly 100% (or slightly less, accounting for fees/slippage). However, the current implied probability sum is approximately 230%, meaning market prices are completely detached from basic reality and mainstream electoral forecasting, driven primarily by blind speculative buying.

This event is highly significant for Turkish assets. Any referendum announcement likely involves extending President Erdogan's term or shifting power structures, triggering volatility in the Turkish Lira and Turkish equities (e.g., ETF ticker TUR). While negligible for global macro assets like DXY or Gold, it is a high-impact event for country-specific exposure.

April 24, 2026 - April 27, 2026, the price of Option_'Yes' surged from 28c to 50.5c. This was driven by rising market expectations that the Erdogan government might reach a compromise with other parties (such as the pro-Kurdish party) to secure enough votes for constitutional changes, along with intensified political speculation regarding the new constitution and early elections. April 12, 2026 - April 14, 2026, the price of Option_'Yes' plummeted from 49c to 27c before rebounding to 38c. This was caused by wild swings in market expectations regarding whether the Turkish ruling party could reach a constitutional compromise with the opposition in the short term, with potential news or rumors triggering panic selling followed by dip-buying.

The prediction market currently assigns a nearly 50% probability (49c) to the referendum, whereas mainstream political analysis generally asserts that reaching a cross-party constitutional consensus is extremely difficult. This is due to the ruling coalition's lack of the 360 parliamentary seats required and the tense political atmosphere exacerbated by the crackdown on major opposition leaders. The market's optimistic pricing likely overestimates Erdogan's short-term ability to win over enough opposition MPs [4, 8, 10].

April 29, 2026 - May 1, 2026, the price of the Democratic Party option plunged from 93.5c to 72.5c (later rebounding to 80.5c), while the Republican Party option spiked from 4.65c to 24.9c. Given that the district's fundamentals (D+25) remain unchanged, this drastic volatility was highly likely caused by a lack of market depth, where a few large trades or dried-up liquidity triggered irrational price jumps. April 11, 2026 - April 16, 2026, price action remained stable. Neither Republican nor Democratic options experienced significant changes, failing to meet the 10-cent threshold for high volatility. The market consensus regarding a safe Democratic victory remains unchanged. March 26, 2026 - April 1, 2026, price action remained stable. Neither Republican nor Democratic options experienced significant changes, failing to meet the 10-cent threshold for high volatility. The market consensus regarding a safe Democratic victory remains unchanged. March 10, 2026 - March 16, 2026, price action remained stable. Although the Republican option saw minor fluctuation (rising from 3.8c to 5.2c), it did not meet the 10-cent threshold for high volatility. The market consensus regarding a safe Democratic victory remains unchanged.

The prediction market currently assigns the Democratic Party an ~80.5% probability of winning, which diverges significantly from mainstream political consensus (e.g., Cook Political Report, Sabato's Crystal Ball). The mainstream view considers LA-02, a D+25 deep-blue district, to have a near 100% Democratic win probability. The discounted market price reflects capital efficiency issues in prediction markets (the opportunity cost of locking up funds for half a year on a guaranteed outcome) and short-term liquidity fluctuations, rather than true election odds.

While anime awards have a dedicated fanbase, the specific category for Best Voice Artist in 'German' is highly niche and obscure. Outside of hardcore fans, the general public rarely thinks about this.

April 19, 2026 - April 21, 2026: The YES prices of multiple options (e.g., Dirk Bublies, Gerrit Schmidt-Foß) crashed to 15-17c on the 20th and quickly rebounded to around 37-39c on the 21st. The reason is the extremely low trading volume (around $54) and lack of liquidity, causing small trades to trigger massive price swings rather than any fundamental news. Previous Analysis: The market maintained relative stability with no moves >10c.

Apr 21, 2026 - Apr 23, 2026, the price of '10-12' spiked from 0.25c to 16.15c before retreating to 10.5c, likely due to an anomalous trade (fat finger) in a very low-liquidity order book or minority speculation on a long-shot event. Apr 4, 2026 - Apr 8, 2026, the price of '25+' plunged from 52c to 35c. This is likely due to a dominant album holding the #1 spot for consecutive weeks recently, reducing expectations for extreme annual turnover. Mar 22, 2026 - Mar 23, 2026, the price of '10–12' crashed from 44c to 3.15c. The previous high price was likely due to a data glitch, fat-finger trade, or irrational speculation on a low-probability outcome, which the market swiftly corrected to align with fundamentals. Mar 11, 2026 - Mar 14, 2026, the price of '25+' slowly recovered from 38.5c to 42c. Market sentiment stabilized after the extreme volatility of late February, placing bets back on high turnover. Feb 24, 2026 - Feb 25, 2026, '25+' previously crashed from 39.5c to 8.5c as the market misjudged a potential multi-week hold. That expectation was falsified in subsequent weeks, leading to a V-shaped recovery.

This is a market share competition question specific to the crypto derivatives sector. While very niche (exotic) for the general public, Hyperliquid's dominance is a hot topic for crypto natives and DeFi traders. Thus, it ranks as moderately exotic.

This event is directly related to the fundamentals of Hyperliquid and its ecosystem token (HYPE). If Hyperliquid is flipped in 2026 (Yes result), it would be a strong signal of weakening competitive moats, likely causing a drop in HYPE price (Score 3). Competitors (like dYdX or Solana-based DEXs like Jupiter/Drift) might benefit, though the correlation is weaker. The impact on broad market assets (BTC/ETH) is negligible.

April 28, 2026 - April 29, 2026, the price of Option_'Yes' surged from 18c to 51c, and subsequently retreated to 28c over the following days. This dramatic volatility was likely driven by short-term speculative rumors in the market regarding major updates or capital injections into potential competitors (such as Jupiter, dYdX, or other decentralized derivative platforms), causing an irrational overreaction that quickly corrected when rumors remained unconfirmed. April 14, 2026 - April 17, 2026, the price of Option_'Yes' retreated from 20c to 12.5c, as the market returned to rationality after brief speculation on competitors' dynamics, confirming that Hyperliquid's lead is hard to shake in the short term. The move did not exceed the 10c threshold. March 3, 2026 - March 18, 2026, the price of Option_'Yes' drifted upwards from 14c to 17.5c, likely reflecting defensive hedging against anticipated competitor incentives (e.g., upcoming TGEs or airdrops) or simply low-liquidity drift, without breaching the >10c volatility threshold. February 24, 2026 - March 2, 2026, the price of Option_'Yes' recovered slightly from 12c to 14c, as the market digested the latest DEX competitive landscape data (e.g., OI growth of Lighter and Aster), entering a repricing phase weighing Hyperliquid's recent volume drop against its long-term moat.
