After years of hints and preparation, electric bike and scooter rental startup Lime has filed for an initial public offering. A micromobility company going public? In 2026? It’s a gamble.

Lime CEO Wayne Ting has talked about an IPO for years. The S-1 document reveals interesting risk factors: $1 billion in current liabilities, and revenue concentrated in the U.K., among other challenges. Will these hurdles be enough to stop Lime?

Uber, which invested in Lime several years ago, still plays a significant role. About 14.3% of Lime’s revenue comes through its partnership with Uber, allowing customers to find and rent scooters and e-bikes through the app.

Lime also warned that a significant portion of rides are concentrated in a few markets. One such market, which accounted for 22.2% of its revenue in 2025, is the U.K. If these markets cool down, it could spell trouble for Lime’s growth plans.

Meanwhile, Uber and Nuro are moving forward with their autonomous vehicle initiatives. A source reveals that Uber’s total financial commitment to Nuro, including its participation in the startup’s Series E round last year and future milestone-based investments, is nearly $500 million.
