How They Trade with 10x and 20x Leverage

Hyperliquid specializes in perpetuals (derivatives without expiry), enabling easy leverage up to 50x (though Alpha Arena caps at ~20x for safety). Leverage amplifies exposure without full capital outlay, speeding feedback loops for AI learning.Mechanics:Margin Types: Isolated (risk limited to position) or cross (shares margin across trades). AIs prefer isolated to contain losses.

Calculation: Leverage = Notional / Margin. E.g., $10,000 account, 10x long BTC ($100K notional) uses $10K margin. A 1% price rise = +10% PnL ($1,000 gain); 1% drop = -10% (-$1,000, or liquidation if margin exhausted).

10x Usage: Balanced for moderate volatility—e.g., DeepSeek's default for diversified holds (ETH long at 10x during rallies). Requires ~10% price move against to liquidate.

20x Usage: Aggressive for high-confidence signals—e.g., Grok's "doubling down" on SOL surges. Only ~5% adverse move triggers liquidation. Used sparingly with tight SL (1–2%).

Why Leverage?: Boosts capital efficiency (trade $200K with $10K) and outcomes—winners like Grok hit +38% in days via 15–20x longs. But it magnifies risks: Claude's 20x ETH long liquidated on news dips, causing -15% overall.

The Alpha Arena is an AI trading benchmark hosted by nof1.ai, where large language models (LLMs) from various providers compete autonomously in real-market conditions using live capital ($10,000 per instance across strategies like "Situational Awareness" or "Max Leverage"). Season 1.5 focused on U.S. stock trading (e.g., volatile tech names like TSLA, NVDA, MSFT, PLTR) over two weeks ending December 3, 2025, with 32 instances totaling $320,000 deployed. Models generate trade ideas, size positions, time entries/exits, and manage risk without human input, using market data, news, and sentiment feeds.The official site for live results, leaderboards, verifiable trade logs, and methodology details is https://nof1.ai/.
