SI, a meme coin on the Solana network, briefly reached a record $64.54 million market capitalization on Sept. 30 as its 24-hour gain exceeded 150%. The token’s market cap later stood at $58.67 million. The figures were recorded at about 7:44 a.m. ET (11:44 UTC), placing the token’s value nearly $6 million below its session high. SI’s move followed market attention toward the “superintelligence,” or SI, narrative in meme-coin trading. President Donald Trump previously said he had signed artificial-intelligence development documents with executives from several technology companies. He described the documents as “a form of constitution” with “moral binding force.” Trump also said artificial intelligence should be called “superintelligence,” a phrase that has appeared in related meme-coin themes.
