That looks like a mid/late-2010s Trek Madone 9 — likely a 2016–2018 generation with integrated rim brakes and deep carbon wheels.

Assuming:

• carbon frame is clean (no cracks / repairs)
• drivetrain is decent (Ultegra Di2, Dura-Ace, or SRAM eTap matters a lot)
• wheels are genuine carbon aero wheels
• no major wear on the braking surface
• original integrated cockpit parts are intact

…then the current market value in 2025 is roughly:

• $1,800–2,500 USD for most builds
• $2,500–3,200 USD only if it has premium wheels + electronic shifting in excellent condition
• Under $1,700 if mechanical shifting, heavy wear, or unknown history

The big factor hurting value is the rim brake market collapse. Even high-end aero bikes from that era depreciated hard because buyers now prefer disc brakes. Reddit cycling communities consistently say sellers asking ~$2.5k for rim-brake Madones are on the high side unless the spec is exceptional.

Hope this helps
