In mega-round venture financing, sequential share placements rapidly expand enterprise valuation. Adding four billion dollars in Round A and two point five billion in Round B lifts post-money valuation from twenty-five to thirty-one point five billion dollars. Because ownership shares reweight against increasing capital totals, rapid funding compresses earlier equity. Baseline founder ownership recedes from sixty-six percent to fifty-two point four percent as new tranches absorb twenty point six percent of equity. Shortening the cadence interval to just two months concentrates dilution velocity to three point eight percent per month. Concurrently, net capital injection builds thirty-one point five months of operational runway against hefty compute burn.
