The bank told Bloomberg it is now "working with exchanges" to resolve faulty options trades from this morning.
Trades in tickers beginning with the letters H through L during the first 17 minutes of trading today are being examined by NYSE Amex Options, Bloomberg also reported.
The development came after a large number of trades outside the normal price range flooded US options markets in the opening minutes of trading, stemming from NYSE Euronext and spilling out to rival exchanges.
A Goldman spokesman confirmed the error to Bloomberg news, saying that any losses "would not be material."
