X charges $0.015 per created post and $0.20 per post containing a URL, according to X Developers' announcement and third-party rate guides.
The legacy Basic ($200 a month) and Pro ($5,000 a month) plans are gone, and Pro subscribers migrate after September 1, 2026.
A $5,000 Pro budget buys about 1,000,000 post reads or 25,000 link posts at today's rates.
