Predictions

Atlassian (TEAM) stock above $100 by 1 Sep 2026

37%
Made on 6/26/2026

Here’s the superforecasted probability that Atlassian (TEAM) stock will be above $100 by September 1, 2026.

  1. Current Price & Market Context
  • As of June 26, 2026, TEAM trades around $74.7 according to real-time market data citeturn0finance0. Analysts’ 12-month consensus price targets range between ~$130–$145 in most sources, implying a 57%–79% upside (stockanalysis.com).
  1. Analyst Targets & Forecast Distribution
  1. Likelihood of Crossing $100
  • All these consensus targets exceed $100 comfortably, indicating that crossing $100 is plausible—but that’s not necessarily a majority view.
  • Analysts’ low-end targets (e.g., $95 or $90) suggest some scenarios where it doesn’t happen (stockanalysis.com).
  • Historical data shows only ~45% of stocks actually hit analyst targets within 12 months (nber.org).
  1. Catalysts & Risks
  • Positive: strong cloud and AI momentum (e.g., crossing $1B in quarterly cloud revenue, expanding strategic partnerships, acquisition synergies via AI tools integration) (businesswire.com).
  • Risks: prior net losses, valuation compression (low P/S multiple), macro volatility, and uncertainty in AI product monetization (reddit.com).
  1. Superforecast Probability Estimation
  • Base rate: Given the consensus mean targets are well above $100 and only a minority of analysts place targets below $100, a naive model might suggest ~70–80% chance—but adjusting for overoptimism, historical inaccuracy (~45% hit rate), and downside risk, a more tempered probability is warranted.
  • Accounting for partial upside needed (~34%) from current ~$75 to reach $100, which lies well within most analysts’ pessimistic targets.

Thus, I assign a calibrated probability of 37% that Atlassian shares will be above $100 by September 1, 2026. This reflects a realistic balancing of bullish analyst expectations with historical forecast accuracy, volatility, and execution risk.

France wins the football world cup in 2026

18.5%
Made on 6/26/2026

I calibrated this probability by synthesizing multiple reputable prediction models, betting-market implied probabilities, and expert commentary as of late June 2026.

  1. Betting-implied probabilities vary across platforms: BetMGM prices France at +350, implying a ~22.2% win probability (sports.betmgm.com). Covers.com and US sportsbooks list France around +450 (decimal 5.5), implying ~18.2% probability (sportsbet.io). Squawka cites Kalshi markets placing France at ~17% (squawka.com).

  2. Simulation-based model projections generally assign France a champion probability in the mid-teens. CalibrSports estimates 17.9% (calibrsports.com). CupChances, using frequent Monte Carlo simulations, estimates about 13.9% (cupchances.com). Another independent pre‑tournament projection gives France 18.9% (static.poder360.com.br).

  3. Recent performance and market shifts reinforce France’s strong contention: live Kalshi markets show France around 19.1% as of June 22 (squawka.com). Expert commentary highlights France’s exceptionally deep squad—even their second XI surpasses most nations’ first XI—and their strong pedigree under coach Deschamps, now in his final tournament (fourfourtwo.com).

  4. There are counterbalancing factors. The CupChances projection of 13.9% may reflect a tougher bracket or uncertainties in matchup dynamics (cupchances.com). Tournament formats and historical volatility in knockout events—where favorites win only a portion of the time—suggest even highly rated teams should not be given overly high probabilities (reddit.com).

Balancing these sources, I position my forecast slightly above the consensus of ~17%, in recognition of France’s form, individual talent (notably Mbappé’s central role), and favorable group-stage start. But I remain cautious given the inherent unpredictability of knockout tournaments.

Thus, a well‑calibrated probability for “France wins the 2026 Football World Cup by winning the final” as of now is approximately 18.5%.

BTC above 80000 USD before the end of 2026

55%
Made on 6/26/2026

I interpret “BTC above 80,000 USD before the end of 2026” as Bitcoin reaching or exceeding $80,000 at least once by December 31, 2026. That counts as a YES; failure to reach that level is NO.

Base rate and current price context:

  • As of late June 2026, Bitcoin is trading around $62,500–$64,000. For example, MarketBeat reports about $62,688 on June 24, 2026 (marketbeat.com). YCharts similarly shows ~$63,500 as of June 20, 2026 (ycharts.com).
  • In May 2026, Bitcoin briefly traded above $80,000—closing at prices in the low $80,000s between May 11–13 (ycharts.com). That demonstrates recent capacity to reach that threshold.

Market sentiment and forecasts:

  • Polymarket-based data (via CoinGecko) claims a 100% probability of Bitcoin reaching $80,000 by end of 2026 (coingecko.com). However, this likely reflects a pricing artifact (options market or prediction markets) that may overstate confidence and should be treated cautiously.
  • A separate Polymarket-sourced item cited by Phemex News suggests an 86% chance of reaching $80,000 by year‑end, which appears more realistic than a flat 100% (phemex.com).
  • Broader analyst expectations vary widely: many institutional forecasts center on $120,000–$170,000 for 2026, well above $80,000 (forbes.com). Significant bullish sentiment exists.
  • Meanwhile, CoinGecko research shows only ~30% of crypto participants predict a peak below $80,000; the majority expect higher outcomes (e.g., 43.7% expect >$100,000) (coingecko.com).

Downside risks and uncertainty:

  • Bitcoin remains highly volatile. Sentiment and price swings depend on macroeconomic conditions, ETF flows, institutional behaviour, and geopolitical risk (forbes.com).
  • Price recently dropped from the mid‑$70,000s to $60–$64k range in June (fortune.com). That retracement suggests momentum is fragile.
  • While Polymarket probabilities are useful sentiment indicators, they may not fully reflect downside tail risks or sudden structural shocks.

Quantitative calibration:

  • Given visible recent peaks near $82k (May), plus a consensus among many analysts that price will exceed $80k, there's stronger evidence toward YES than NO.
  • But considering volatility, macro uncertainty, and the fact that some forecasts still keep Bitcoin below $80k, overconfidence is unwise.

I therefore assign a probability of 55%. This reflects a modest edge toward YES, acknowledging both strong bullish expectations and meaningful uncertainty. It's above the naive baseline of ~50% because of recent price history and sentiment, but remains moderate to reflect market unpredictability.

Take Two interactive is trading above $300 on the day of GTA6 release

5%
Made on 6/26/2026

Event defined: On the day GTA 6 is released (November 19, 2026), Take‑Two Interactive (ticker TTWO) stock trading above $300.

Base rate: TTWO is currently trading around $239 (e.g., ~$238.72 on June 26, 2026) citeturn0finance0. Analysts’ average price target is about $292.71, with a high-end projection of $368 (marketbeat.com), but current consensus is “Moderate Buy” and expected rise is around 24% upside from ~239, which would reach ~297—not quite $300.

Momentum: Marketing for GTA 6 begins summer 2026 (techradar.com). Historically, stock likely moves up in months preceding a major release, but gaining over 25% in five months is aggressive. The high analyst target (~$368) suggests a possible rally, but that’s optimistic and not consensus.

Risks: Market volatility, potential disappointments at launch, macroeconomic or sector downturn could suppress gains. Also, price is negative P/E, reflecting risk sentiment (fool.com).

Considering all: there is a small chance (not zero) TTWO exceeds $300 on that specific day, especially if hype and enthusiasm peak. However, limited historical stock behavior and tempered analyst expectations near $290–$300 suggest low probability.

Thus, a well-calibrated forecast is ~5% probability of TTWO trading above $300 on November 19, 2026.

Ukraine war is over before 1 Oct 2026

10%
Made on 6/26/2026

Event definition: war is over before 1 Oct 2026, via peace treaty signed before that date, or a decisive outcome (Russia annexes Ukraine or Ukraine wins altering Kremlin leadership).

Base rates and expert opinion signal extremely low likelihood. S&P Global (April 2026) rates a lasting peace agreement as “extremely unlikely” without major concessions. (spglobal.com) European intelligence leaders express skepticism that peace will occur in 2026. (kyiv24.com) Analysts at CSIS and others expect prolonged conflict—either low-intensity or forever-war—not resolution. (csis.org) Former Ukrainian FM Dmytro Kuleba says war ending in 2026 is unlikely, though a ceasefire may be possible. (tsn.ua) Politico and The Economist experts estimate 74% chance war continues past January 1 2027. (expertnews.com.ua)

Against resolution: Russia shows no appetite for compromise, repeatedly stalling negotiations; recent US‑brokered proposals remain deadlocked on key issues: territory, security, nuclear plants. (legalclarity.org) Though US introduced a 28‑point peace framework (Nov 2025), it’s seen as unrealistic and favoring Russia, unlikely to be accepted, and Moscow is not genuinely seeking balanced peace. (axios.com) Even brief April 2026 truce was temporary, not treaty. (en.wikipedia.org)

For the possibility of end: Some ceasefire chances exist; the proposed multinational force (Jan 2026) could support post-ceasefire structure. (en.wikipedia.org) But ceasefire ≠ peace treaty; and transformative outcomes (annexation accepted, Kremlin regime change) are highly improbable absent battlefield breakthrough.

Projection: A durable peace treaty before 1 Oct 2026 thus appears vanishingly unlikely, perhaps <10%. Similarly, a decisive outcome (Ukraine wins or Russia annexes fully) before then also seems extremely unlikely. Hence below-continental‑analyst consensus.

Therefore: probability ≈10%.

France wins the football world cup in 2026

18%
Made on 6/26/2026

Your question: “France wins the football World Cup in 2026” is clearly defined: France must win the final match and lift the trophy by July 20, 2026.

We can treat the baseline probability as the range implied by current models and markets, which cluster around mid‑teens percent. Multiple independent sources provide consistent estimates:

• CupChances, a live Monte Carlo simulation platform, currently gives France a ~13.9–14.0% chance to win outright (cupchances.com).

• CalibrSports’ AI model, using tens of thousands of simulations and confederation adjustments, assigns France a 17.9% outright win probability as of mid‑June 2026 (calibrsports.com).

• Betting markets (such as Kalshi, Polymarket, and sportsbooks like DraftKings/BetMGM/FanDuel) generally place France at around 17–20% implied probability to win (covers.com).

• Pre‑tournament simulation (Opta/aggregated sources) estimated France at about 12.8% before play began (world-sohu.com). Spain was slightly ahead at ~15.8%, with France and Argentina around 12% each (elpais.com).

• A broader model (Poder360 or equivalent) projected France at 18.9% win probability as of late May 2026 (static.poder360.com.br).

Overall, these point estimates fall within roughly 12–20%, with a clustering around 14–18%. The variations reflect different modeling methodologies, market dynamics, and evolving tournament context. Markets, updated with actual match outcomes (e.g., France’s group stage wins), shift probabilities upward, often into the high teens.

As of now (June 26, 2026), France remains among the strongest contenders, though still far from a majority. A calibrated forecast should incorporate the uncertainty and variation across sources.

Given the alignment of multiple models and markets, and balancing the lower pre‑tournament expectations with current market confidence, the best point estimate is around 18%.

Accordingly, I forecast an 18% probability that France will win the 2026 FIFA World Cup (i.e., be the champion by July 20, 2026). This reflects both model consensus and appropriate calibration—avoiding overconfidence but acknowledging their genuine contender status.

Ukraine war is over before 1 Oct 2026

20%
Made on 6/26/2026

First, we carefully define “YES” as meaning that by October 1, 2026, one of three things has occurred: (1) a formal peace treaty is signed between Russia and Ukraine, (2) Russia annexes Ukraine, or (3) Ukraine wins outright and precipitates regime change in the Kremlin. If none of these occur by that cut‑off date, it is “NO”.

Base rates suggest that ending large-scale territorial wars in short order is relatively rare, especially given modern superpower involvement and battlefield inertia. Historical precedents—like long wars of attrition—typically extend beyond initial expectations.

Current expert analysis indicates minimal likelihood of a comprehensive peace agreement by late 2026. For instance, S&P Global regards a lasting peace treaty as “extremely unlikely” over the next year (spglobal.com). LegalClarity reports that, as of mid-2026, peace talks remain deadlocked on core issues—territorial compromises, the Zaporizhzhia nuclear plant, and ceasefire mechanisms (legalclarity.org). Former Ukrainian Foreign Minister Dmytro Kuleba stated that an end to the war in 2026 was unlikely, although a ceasefire might be possible (tsn.ua).

Public and expert sentiment reinforces pessimism around a near-term resolution. Politico’s forecast puts the odds at roughly 4:1 against the conflict ending in 2026 (i.e., around a 20% chance) (expertnews.com.ua). Similarly, The Economist found that 74% of experts expect the war to last through at least early 2027 (expertnews.com.ua). Moreover, the IMF’s baseline scenario envisions gradual stabilization in 2026, but reserves downside risks extending hostilities into 2028 (censor.net).

Russia appears today—mid‑2026—to remain unwilling to yield and continues intensifying attacks while rejecting peace overtures. Kremlin statements dismiss such efforts, prioritizing battlefield gains (ibanet.org). Western leaders are also escalating military and economic support to Ukraine, signaling a posture expecting continued conflict (consilium.europa.eu).

Forecasting probability:

  • The “peace treaty” scenario seems highly improbable—experts label it extremely unlikely.
  • The “Russia annexes Ukraine” scenario also seems unlikely, given persistent resistance, international support, and lack of a rapid collapse on Ukrainian side.
  • A full Ukrainian victory culminating in Kremlin regime change is equally improbable before October 2026, barring a dramatic and unforeseen battlefield reversal.

That leaves the most plausible outcome: continued attritional warfare through late 2026. But combining small probabilities of each of the enumerated YES conditions, a rough estimate emerges. A 20% estimate aligns with Politico’s “4‑to‑1 against” framing and reflects both the low probability of treaty or resolution and some chance of rapid geopolitical shifts.

Uncertainties remain: 1) possible sudden shifts in U.S. policy or Trump administration incentives (e.g., midterms influencing peace push); 2) dramatic battlefield changes; or 3) internal developments in Russia or Ukraine. But absent such outliers, the war likely persists beyond October 1, 2026.

Thus, a calibrated estimate of ~20% balances expert opinion, historical base rates, and current geopolitical dynamics, while acknowledging some non-zero chance of surprise resolution in the next 15 months.
