The effective shelf creates persistent overhang — monitor daily ATM volume and any 424B5 prospectus supplements for actual takedowns. The cross-filing amplifier (effect-ipo-context + effect-shelf-context) supports elevated impact. Historical calibration shows score-6/7/8 filings on this ticker have negative net alpha at T+20, reinforcing bearish bias.

Executive Summary
Serve Robotics' $300M universal shelf registration (S-3, File No. 333-295746) became effective on May 14, 2026. This unlocks the ability to sell up to $300M in securities, including a $150M at-the-market (ATM) program, creating immediate dilution overhang for a company with a $676M market cap and rapid cash burn ($49M net loss on $3M Q1 revenue).

- Total offering size up to $300M, including $150M ATM program

- Filed 4 days after Q1 2026 revenue of $3.0M and net loss of $(49.0M)
