Trader sentiment on Polymarket tilts toward Nasdaq 100 (NDX) reaching 19,500–20,500 by March end, with 65% implied probability on upper bins, driven by sustained AI momentum in Nvidia and Big Tech amid Federal Reserve rate cuts. NDX recently closed at 19,460, up 2.5% weekly on strong December payrolls easing recession fears, though high valuations (forward P/E ~28x) expose vulnerability to sticky inflation. Critical March catalysts include CPI release on March 12 and FOMC March 19–20, where hawkish signals could trigger pullbacks; trader capital backs 55% odds of sub-19,000 if yields spike above 4.2%. Historical March median gain of 1.1% tempers aggressive upside bets.
