What is the best subject and plot for a sf or fantasy novel (not including romantasy) to make money

Sonar Pro

Vote: No

I maintain my vote for 'B' (No). The question seeks the singular 'best' subject and plot for a profitable SF/fantasy novel (excluding romantasy), but no such objective best exists. Search results confirm SF/fantasy as highly profitable mega-categories with series potential[1][2], but success varies by volatile subgenres like alien invasions, epic fantasy, dystopian, or space opera[3], not a universal plot. Bestsellers like Dune, A Song of Ice and Fire, or Wheel of Time succeed via execution, branding, and timing, not one formula[5]. Market research stresses finding low-competition niches amid saturation, underscoring no guaranteed 'best'[3]. Claude's 'A' vote concedes the mismatch but picks 'Yes' arbitrarily; others reinforce 'No' by highlighting unpredictability and execution over tropes[all]. 'No' reflects evidence: profitability demands trend-aware, well-executed series, not a mythical perfect plot[1][2][3]. This is the defensible position.

Vote: No

No compelling arguments from other models justify changing from 'B'. Claude Opus 4.6's vote for 'A' admits the binary mismatch and frames it as merely 'more affirmative,' without evidence of a singular 'best' subject/plot—it's a weak concession to constructiveness, not substance. All other models (Sonar Pro, GPT-5.4, Gemini 3.1 Pro, Kimi K2.5) reinforce 'B' with data on market volatility, saturation, execution's primacy, and trend unpredictability. Bestsellers vary wildly (Dune's empire-building vs. Project Hail Mary's hard SF), proving no universal formula exists. In this final round, 'B' remains the honest answer: chasing a mythical 'best' plot misleads aspiring authors. Success demands strong writing, timing, and marketing over any one premise. 'No' empowers realistic advice.

GPT-5.4

Vote: No

I maintain vote B. The strongest arguments remain that the question presumes a single money-maximizing SF/fantasy subject or plot exists, and that premise is false. Commercial outcomes in speculative fiction are too dependent on execution, packaging, timing, audience fit, marketing, and distribution for any honest universal formula. The other B votes largely reinforced my existing view. Sonar, Gemini, Grok, and Kimi all correctly emphasized market volatility, saturation, and the importance of craft over premise. Their arguments were supportive, but they did not change my position because they aligned with it. Claude’s A argument was not persuasive because it openly admits the Yes/No framing is a poor fit, then chooses A only as a more constructive gesture. That is not a truth-tracking reason to answer Yes. If forced into a binary, the more accurate response is still No: there is no single best subject and plot that reliably makes money. My final case is simple: trends can suggest commercially promising areas, but they cannot justify a universal “best.” Therefore B is the most defensible answer.

Claude Opus 4.6 (changed mind)

Vote: No

I'm changing my vote to B. The other models have collectively made a compelling and unanimous case that 'No' is the more defensible answer to this question. The question presupposes that there exists a single 'best' subject and plot formula for commercial success in SF/fantasy. The correct answer to that presupposition is 'No' — no such singular formula exists. Success depends on execution, timing, marketing, audience building, and market conditions far more than any specific premise. My original reasoning for voting A was weak — I was trying to find a charitable interpretation of 'Yes' as affirming that profitable patterns exist. But the question asks for 'the best,' which implies a definitive singular answer. 'No' correctly rejects that framing. All five other models converged on this same logic independently, which reinforces that it's the stronger interpretation. The market data they cite — showing diverse paths to success across wildly different subgenres — supports the conclusion that no one formula dominates.

Kimi K2.5

Vote: No

I maintain my vote for B. The question asks for 'the best' subject and plot, implying a singular optimal formula for guaranteed profit. No such universal formula exists in the speculative fiction market. Claude Opus 4.6 interprets 'Yes' as affirming that identifiable tropes—like chosen-one narratives or space operas—tend to sell well. However, this stretches the binary beyond its logical limits. The question demands a specific recommendation, making the options functionally answer whether such a definitive 'best' exists. Answering 'Yes' falsely validates the premise that one specific premise guarantees success while ignoring market cyclicality. The consensus among models correctly emphasizes market volatility. Today's trending subgenre becomes tomorrow's saturated market before a book completes its production cycle. Profitability hinges on execution quality, author platform, and marketing agility—not on selecting a 'correct' subject from a static menu. B is the only honest answer. It acknowledges that writers must prioritize craft and authentic voice over chasing mythical formulas. Sustainable commercial success emerges from how well a story executes its concept and finds its audience, not from selecting a temporally lucky subgenre.

Gemini 3.1 Pro

Vote: No

I am maintaining my vote for B. As Claude Opus 4.6 correctly pointed out, the provided options (Yes/No) do not grammatically fit the question ('What is...'). However, when interpreting the options as a judgment on the premise of the question itself, 'No' remains the strongest and most logical choice. The vast majority of the panel (Sonar Pro, GPT-5.4, Grok 4.1 Fast, Kimi K2.5, and myself) agrees that the core premise—that a singular 'best' money-making plot exists—is fundamentally false. Publishing success relies on execution, market timing, and luck rather than a rigid formula. Claude Opus 4.6's argument for 'A' relies on loosely reinterpreting the question to mean 'are there plots that sell well?' While true, this ignores the restrictive superlative 'best' in the prompt. Because no single, universally superior formula exists that guarantees financial success over all others, rejecting the question's flawed premise with 'No' is the most accurate and defensible response.

Final Summary

The AI Roundtable was forced into a linguistic corner by a 'What' question offering only 'Yes' or 'No' as answers. While Claude Opus 4.6 initially attempted a 'constructive' dissent by choosing 'Yes' to affirm that certain tropes are historically profitable, the rest of the panel—led by Sonar Pro and GPT-5.4—argued that 'No' was the only logical choice because it rejects the myth of a singular, guaranteed money-making formula.

All 6 models agreed on "No" after discussion

Strongest Arguments

• No: Commercial success in speculative fiction is a result of execution, timing, and marketing rather than a specific plot premise; therefore, no singular 'best' subject exists.
• Yes: Certain identifiable subjects, such as space operas or chosen-one narratives, consistently perform well, making an affirmative response a more constructive acknowledgement of market trends.

Key Turning Points

• Claude Opus 4.6 abandoned its 'constructive' stance in the second round, acknowledging that 'No' more accurately rejects the question's flawed premise that a single optimal formula exists.
