The only fetched page with usable content was https://coinpost.jp/?p=25907, and it is materially unrelated to the claim, so it cannot support the statement. Both user-provided X links could not be fetched, and web-search corroboration did not surface a clearly matching authoritative page confirming that Bitcoin's market capitalization rose above $1.5 trillion and that this was its highest market value since January 2026. Given the mismatch in the CoinPost source and lack of accessible corroborating primary evidence, the claim cannot be verified from the evidence gathered in this run.
