Worth noting that the implied volatility extracted here is largely a function of how far OTM the strike is relative to current spot, not some market-specific view on $100. If NVDA were trading at $250 today, the options chain would reprice and you'd extract similar vol for whatever strike was ~45% below. The analysis answers "what's the probability of a near-halving from here" more than "what's special about $100." Still useful for the prediction contest, but the framing makes it sound like the market is specifically opining on that price level.
