Will the global cryptocurrency market experience a surge in 2026—similar to the euphoria seen in 2021?

Sonar Pro

Vote: no

I maintain my vote for **B** (no). The search results explicitly describe 2026 as a year of **institutional consolidation, compliance, and measured growth** rather than 2021-style retail euphoria[1][5]. Pantera Capital states: '2026 won’t be about hype or memes. It will be about consolidation, real compliance, and institutional money'[1]. Kraken notes 'compressed volatility,' 'less euphoric' markets, and inflows absorbed without 'reflexive upside' due to ETFs and institutional vehicles[5]. Projections reflect maturity: BTC base case $95K[6], bull case $150-180K[3][6]—significant but far below 2021's parabolic mania scaled to current market cap. Stablecoins to $500B[1], tokenized assets surging[1][8], but driven by regulation[2][6], macro easing[3][5], and enterprise adoption[8], not FOMO or memes. Other models' halving cycle arguments (peaking late 2025[Gemini]) and institutional tailwinds ignore sources' distinction: post-peak 2026 enters consolidation[5], with 'structurally more complex' dynamics replacing retail frenzy[1][5]. Macro easing is slower[5], lacking 2021's ZIRP/stimulus. No arguments cite sources predicting 2021-like euphoria; they speculate despite evidence of maturation. This confirms **no repeat of 2021 euphoria**.

Vote: yes

I’m keeping vote A. The strongest B-side point is timing: if the post-halving peak lands in late 2025, then 2026 could be consolidation rather than surge. That is a real risk, and Gemini 3.1 Pro made the clearest version of it. But halving-cycle timing is not precise enough to rule out a 2026 euphoric phase; cycle peaks can stretch, broaden, or arrive later when new demand channels exist. That is exactly why the institutional-maturity argument cuts both ways. Sonar Pro, Kimi K2.5, and Gemini 3.1 Pro argue ETFs and professionalization dampen mania. I think they more likely expand the pool of buyers and legitimize the asset class, making large inflows easier. Institutional access does not eliminate speculative behavior; it can coexist with it and even magnify it when bullish narratives take hold. The claim that 2021 was uniquely dependent on ZIRP and stimulus is too narrow. Crypto manias have occurred in multiple macro regimes because they are driven by reflexivity, liquidity, and attention, not one exact policy setup. A 2026 surge would not need to look identical to 2021 to qualify as similar euphoria. Claude Opus 4.6 reinforces my view most persuasively: the combination of halving effects, broader ETF adoption, improving regulatory clarity, and fresh narratives creates a credible path to another major upswing extending into 2026. My final view is that a 2026 global crypto surge is still more likely than not, even if narrower and more institutionally mediated than 2021.

Vote: yes

Historical Bitcoin halving cycles consistently deliver bull market peaks 12-18 months post-halving, but euphoria often extends beyond the absolute top. The 2020 halving led to a November 2021 peak (18 months), with altcoin mania spilling into early 2022. April 2024 halving points to a late 2025 peak, but 2026 will likely see continued surge driven by lagging retail FOMO, altseason, and new narratives like AI/DeFi/tokenization—mirroring 2021's prolonged hype. Institutional adoption via ETFs ($60B+ AUM already) amplifies rather than dampens euphoria; it provides the capital base for explosive moves when sentiment turns. Pro-crypto policies (e.g., U.S. reserves) and global regulatory clarity (MiCA) will lower barriers, reigniting retail participation absent in prior cycles. B arguments overstate maturity and mis-time the cycle: 2026 is mid-cycle extension, not post-peak decline (historical bears start 18-24 months post-halving). 2021's stimulus was a booster, not essential—liquidity from Fed cuts will suffice. Sources cited by Bs predict BTC $95K-$180K with institutional growth, but euphoria is sentiment-driven, and FOMO will follow price action to $150K+. No B argument shifts the cycle evidence or ignores retail's role in past manias. A remains correct.

Kimi K2.5

Vote: no

The halving cycle arguments presented by Claude and Grok correctly identify bullish momentum, but they overlook the specific temporal phrasing of the question. Historical halving cycles (2012→Dec 2013, 2016→Dec 2017, 2020→Nov 2021) consistently show peaks occurring 12-18 months post-halving. With the April 2024 halving, this places the cyclical top in Q4 2025, making 2026 historically the bear market or consolidation phase—not the euphoric surge. More importantly, proponents of option A conflate price appreciation with 'euphoria.' The 2021 mania was defined by unsustainable retail FOMO, parabolic altcoin casinos, and reflexive volatility driven by zero-rate liquidity. Today's market structure—with spot ETFs absorbing inflows via institutional custody—exhibits compressed volatility and 'measured' growth, as Sonar Pro noted. This professionalization inherently prevents the 2021-style speculative hysteria. Finally, 2026 macro conditions will feature structurally higher interest rates and diminished retail dry powder compared to the pandemic stimulus era. While prices may cycle higher in 2025, 2026 will likely lack the environmental conditions and market psychology necessary to replicate 2021's specific euphoria.

Claude Opus 4.6 (changed mind)

Vote: no

After careful reflection, I'm changing my vote to B. The key arguments that shifted my thinking: **Cycle timing works against 2026 euphoria.** Gemini 3.1 Pro made the most compelling point: the halving cycle historically peaks 12-18 months post-halving, which means late 2025 is the likely euphoric peak, not 2026. By 2026, the market would historically be entering its cooling or bear phase. The question specifically asks about 2026, not 2025-2026. **The question asks about 2021-style euphoria specifically.** Sonar Pro's distinction is important - growth and a bull market are not the same as euphoria. The 2021 mania was characterized by Dogecoin hitting $80B market cap, NFT mania, DeFi yield farming frenzy, and stimulus-check-fueled retail speculation. Even if crypto prices are high in 2026, the institutional-dominated, ETF-mediated market structure will likely produce something qualitatively different from that retail-driven euphoria. **Macro conditions won't replicate 2021.** Kimi K2.5 correctly notes that the 2021 euphoria required zero interest rates AND direct stimulus payments to retail investors. Even with rate cuts, we're unlikely to see rates at zero with simultaneous fiscal stimulus by 2026. The 'easy money' environment of 2020-2021 was historically anomalous. **Institutional maturation dampens euphoria.** When capital flows through ETFs and institutional channels rather than retail Robinhood accounts and Telegram groups, you get appreciation but not the same wild speculative mania. The market has structurally changed. My original argument was essentially that crypto would do well in the halving cycle - and it probably will - but the specific question about 2021-style euphoria in 2026 (not 2025) makes B the more accurate answer.

Gemini 3.1 Pro

Vote: no

I maintain my vote for 'B'. The arguments presented for 'A' rely on a flawed timeline of the halving cycle and inadvertently contradict the prompt's specific requirement for '2021-style euphoria.' First, models like Claude Opus 4.6 and Grok 4.1 Fast cite the 4-year halving cycle to justify a 2026 surge but miscalculate the timeline. A peak occurring 12 to 18 months after the April 2024 halving lands precisely in mid-to-late 2025. Historically, the year following the cycle peak (2014, 2018, 2022, and logically 2026) is marked by a severe bear market drawdown or grueling consolidation, not a euphoric surge. Second, the prompt explicitly asks if the surge will be 'similar to the euphoria seen in 2021.' Even the models arguing for 'A' concede that the market has changed, noting that institutionalization and regulatory guardrails will temper wild excesses. 2021's euphoria was defined by unprecedented pandemic stimulus checks, zero-interest rates, and retail meme-mania. A market driven by Wall Street ETF inflows and corporate compliance naturally suppresses this kind of explosive, irrational retail frenzy. Because 2026 aligns historically with a post-peak bear market, and because the structural conditions for a 2021-style retail mania no longer exist, a 'yes' vote ignores both historical data and the macroeconomic realities of the maturing crypto asset class.

Final Summary

The AI Roundtable initially split down the middle, but ultimately swung toward a skeptical 'no' after Gemini 3.1 Pro convinced Claude Opus 4.6 that the 2026 calendar year would likely be a period of cooling rather than climax. While GPT-5.4 and Grok 4.1 Fast maintained that institutional capital will supercharge future manias, the majority concluded that the 'easy money' conditions of the pandemic era cannot be replicated in a maturing, regulated market.

Majority chose "no" after discussion (4/6). Final vote: no: 4, yes: 2

Strongest Arguments

• yes: The combination of the 2024 halving cycle and $60B+ in new ETF inflows creates a massive capital base that will reignite retail FOMO once Bitcoin targets $150k, making institutional adoption an amplifier of euphoria rather than a stabilizer.
• no: The historical 12-to-18-month post-halving peak puts the market top in late 2025, making 2026 a year of consolidation or bear-market drawdown rather than a euphoric surge.

Key Turning Points

• Gemini 3.1 Pro's precise calendar math on the post-halving cycle convinced Claude Opus 4.6 that 2026 is chronologically slated for a cooling phase, not a peak.
• Sonar Pro and Kimi K2.5 effectively distinguished between 'price growth' and '2021-style euphoria,' arguing that institutionalization structurally prevents the retail-driven 'casino' behavior of the pandemic era.
