The first corporate action on a Coinbase tokenized stock
At 18:29:45 UTC on 14 September 2026, in Base block 51310619, GOOGLc's multiplier()moved for the first time. Across all thirteen of Coinbase's tokenized equities there had never been a split, a reverse split or a dividend adjustment until this one.
Nothing announced it. It was found by comparing yesterday's multipliers to today's, which is the only reason this page can state the block.
What actually changed
| read | block 51310618 | block 51310620 | |
|---|---|---|---|
| multiplier() | 1000000000000000000 | 1000377118676784179 | changed |
| totalSupply() | 625695500195 | 625695500195 | unchanged |
| balanceOf(Uniswap V4 PoolManager) | 49170507575 | 49170507575 | unchanged |
The multiplier rose by 0.0377%. Supply did not move, so nothing was minted. The largest holder's balance did not move either — and that holder is a contract, Uniswap V4's PoolManager, holding 491.70507575 GOOGLc by the number the chain reports.
Its entitlement is now about 0.185 shares higher than the block before. Every contract, wallet and indexer reading balanceOf shows the number from before.
Check it yourself

Why 0.0377% is the interesting part
A split is a round number. This is not one, and it is far too small to be one — it is the shape of an accrual: a small, irregular entitlement increase of the kind a dividend or a securities-lending return produces.
Base's own Request for Builders said tokenized stocks “may have yield-generating mechanics” and called the result productive assets. This is what that looks like on chain, and it means the next one is a matter of weeks rather than years. Anything built on these assets that caches a balance will be wrong again, on a schedule, without being told.
We are not classifying this as scheduled or emergency, because one sample is not a taxonomy. It is the first sample there has ever been.
What this does not say
It does not say anyone lost money — a multiplier is a unit change, not a price change, and positions are redenominated rather than revalued. It does not say Coinbase did anything wrong; the mechanism is documented B20 behaviour and it worked. It does not predict when the next one lands, or on which ticker.
It says one thing: on these tokens the balance and the entitlement are different numbers, that difference is no longer hypothetical, and anything reading the first while meaning the second is quietly wrong from block 51310619 onward.
