Definition ambiguity risk exists. The rule strictly defines market cap as 'outstanding shares multiplied by closing price', which is the standard secondary market definition. However, IPO valuations cited in media often refer to 'Fully Diluted Valuation' (including option pools). For tech firms, the fully diluted figure can be 10-20% higher than the market cap based on outstanding shares. If Ledger claims a $4B valuation (fully diluted) but the strict market cap is only $3.5B, the market would resolve to 'No', contradicting public headlines.

Ledger's valuation is highly positively correlated with broader crypto market sentiment, specifically Bitcoin (BTC) prices. If BTC crashes pre-IPO (as mentioned in search results dropping from $126k to $70k), Ledger's hardware wallet sales projections and valuation would suffer a structural shock. Coinbase (COIN), as a public crypto infrastructure peer, serves as a direct pricing anchor; its multiple compression would drag down Ledger.

April 27, 2026 - April 30, 2026, the price of the $6B option surged from 19c to 51c, a massive jump of 32c, while the $1B option crashed from 49.75c to 29.95c. This caused an extreme pricing inversion ($6B probability far exceeding $4B, $5B, and $1B), completely deviating from basic logic, presumed to be caused by irrational large buy orders or fat-finger errors in an illiquid market. April 13, 2026 - April 14, 2026, the price of the $4B option surged from 30c to 40.5c, a jump of over 10c, causing a severe pricing inversion with the $3B option (40.5c > 36.5c), likely driven by the impact of a single irrational large buy order. March 27, 2026 - March 30, 2026, the price of the $1B option fell from 75.2c to 55.8c, a drop of nearly 20c, indicating a shake in short-term certainty or capital rotation regarding Ledger's successful IPO or listing at such a low valuation. March 13, 2026 - March 15, 2026, the price of the $4B option crashed from 49c to 12c, a 75% drop, directly causing the severe price inversion at the time (falling below the $5B option). Meanwhile, the $1B option rebounded from 70.9c to 81.4c, indicating increased market confidence in the IPO taking place, but a breakdown in the pricing mechanism for specific valuation ranges. February 23, 2026 - February 24, 2026, the price of the $4B option surged from 26c to 51.5c, reflecting an overheated market reaction to high valuation targets, briefly exceeding the $3B option. February 9, 2026 - February 10, 2026, the price of the $4B option rose from 21c to 37c, a delayed reaction to rumors of Ledger seeking a $4 billion valuation.

The implied probabilities of the options in the current prediction market exhibit severe logical inversions (e.g., $6B is priced higher than $1B, $4B, and $5B). This severely contradicts any rational financial pricing model and mainstream market common sense. This divergence is entirely caused by market microstructure flaws and irrational speculation under extremely low liquidity, rather than a shift in fundamental consensus.
