Bitcoin's nominal price may be hovering near highs, but when adjusted for the broad money supply, the picture looks less rosy. The BTC-to-M2 ratio is flashing a warning pattern after the 2023–2025 climb, according to M2-adjusted analysis. At the same time, Polymarket bettors are pricing in a 99.95% probability that Bitcoin will remain above $56,000 — a level that has become a key psychological floor.
Behind the BTC-to-M2 warning
The BTC-to-M2 ratio measures Bitcoin's price against the global money supply. After the 2023–2025 rally, the ratio is now signaling that Bitcoin's real strength relative to liquidity has weakened. The same analysis suggests the S&P 500 also appears weaker than its nominal highs imply when adjusted for M2. This isn't a crash call — it's a caution that nominal prices may be outstripping underlying monetary expansion.
The S&P 500's own M2 adjustment
The S&P 500's M2-adjusted performance mirrors Bitcoin's pattern. Both assets have climbed in dollar terms, but once you account for the trillions added to the money supply since 2020, the gains look more modest. The M2 metric doesn't predict a sell-off, but it does suggest that the easy tailwind from liquidity expansion is fading. For crypto and equities alike, the next leg may need to come from genuine demand rather than monetary inflation.
Polymarket's near-certain floor
Polymarket's 99.95% probability for Bitcoin staying above $56,000 is about as close to certainty as prediction markets get. That level has held since mid-2025 and is now baked into options and derivatives pricing. The tension is clear: the M2-adjusted view warns of weakening momentum, while the market is betting the floor holds. If the M2 signal is right, the Polymarket probability could eventually reprice — but for now, bettors see no reason to doubt $56K support.
The coming weeks will test whether the Polymarket probability holds or adjusts to the M2 reality. If the BTC-to-M2 ratio continues to weaken, that $56,000 floor could face its first real challenge since the metric turned cautious.
