The IPO Comeback: Why Tech Giants Are Finally Going Public | All-In Liquidity IPO Panel
Key insights
Companies
- Cerebras Systems - Andrew Feldman's wafer-scale AI chip company, IPO'd weeks before this panel at a $185 price (upsized twice), opening near $320/share, ~$50-60B market cap
- Planet Labs - Will Marshall's earth-imaging satellite company, went public via SPAC in 2021 at ~$2B, stock 10x'd from $5 to $50/share over the following year
- Google - Cerebras's and Planet Labs's largest single investor (has not sold a share); also a partner testing TPUs launched into space with Planet Labs
- Nvidia - Reference architecture Cerebras deliberately avoided copying; GPUs used in early space-compute experiments
- SpaceX - Cited as the comparison case for a possible future mega-IPO and pioneer of the 'dribble lockup' share-release structure
- Altimeter Capital - Brad Gerstner's firm; early Cerebras investor still under lockup at time of the panel
- Capricorn - Early Planet Labs VC investor that held shares through the 2021 SPAC and the subsequent run-up
- Founders Fund - Early Planet Labs investor (Peter Thiel's fund)
- DST Global - Yuri Milner's fund, later-stage Planet Labs investor
- OpenAI - Cited as a Cerebras customer running inference 15-18x faster than on GPUs
- Anthropic - Referenced alongside OpenAI and SpaceX as one of the era's mega-valuation private companies
Techniques and frameworks
- Dribble lockup - A post-IPO share-release structure (pioneered by Cerebras/SpaceX-adjacent bankers) that releases locked-up shares gradually over ~6 months tied to performance hurdles, instead of a single lockup-expiry cliff
- Wafer-scale chip architecture - Cerebras's core design bet: build a dinner-plate-sized chip with memory next to compute, rejecting the GPU form factor entirely to avoid competing head-on with Nvidia
Summary
This is a live panel recorded at an All-In event, moderated primarily by Altimeter Capital's Brad Gerstner (with Jason Calacanis present and opening the segment), featuring two CEOs of newly public, AI-adjacent companies: Andrew Feldman of Cerebras Systems (the AI chip maker that had IPO'd roughly three weeks earlier) and Will Marshall of Planet Labs (the earth-imaging satellite company that went public via SPAC in 2021). The conversation opens with both founders describing the anticlimax of going public: enormous procedural overhead, a celebratory moment for employees and their families, and then a return to the exact same operational problems the business had the day before. Feldman is candid that Cerebras got its IPO timing right only after nearly a decade of getting it wrong, while a shift in market conditions over the final twelve months made the offering wildly oversubscribed.
The panel then turns to the economics of staying private too long. Gerstner argues, using Planet Labs's own trajectory (a ~$2B SPAC entry in 2021 followed by 90% of the company's value creation arriving in years three and four, and a later 10x stock move) as Exhibit A, that the venture industry's decade-long "stay private forever" doctrine cost LPs enormous upside by keeping high-growth companies out of public markets during their steepest value-creation years. He shares a personal story of an LP-driven decision to distribute shares early in a company that later ran from $3-4B to $50B, and frames the newer "dribble lockup" structure (gradual, performance-gated share releases instead of a hard lockup-expiry cliff) as one mechanism the market is building to make later, staged liquidity events more palatable to both founders and investors.
Marshall and Feldman then each explain the technical bets underlying their businesses. Marshall lays out the case for space-based data centers: launch costs have fallen roughly 10x in a decade and are still a few years from the $200-300/kg threshold where space-based compute becomes cheaper than terrestrial, largely because continuous, unobstructed sunlight in a dawn-dusk orbit delivers about five times the usable solar energy per panel with no batteries required. He also credits satellite miniaturization (from billion-dollar, 20-ton satellites to sub-hundred-kilogram units) as a bigger unlock than launch costs alone. Feldman explains Cerebras's core architectural bet: AI unlocked entirely new categories of compute problems (images, language, real understanding rather than storage), and rather than build a faster GPU, Cerebras built a wafer-scale chip with memory placed directly next to compute, reasoning that matching Nvidia's own architecture could never produce the 15-18x speed advantage Cerebras eventually delivered to customers like OpenAI.
The episode closes with both founders framing the next several years as an acceleration point where AI and space converge: Marshall's vision of "planetary intelligence," where large language models trained only on internet text gain access to real-world sensing data, and a shared view among the panelists that public-market scrutiny sharpens execution rather than distracting from it.
